Japanese Unexamined Patent Publication No. 2006-340777

However, in the tongue movement monitoring device during the sucking motion of the baby, the sensor is placed at the base end portion of the base. Therefore, when the base is placed in the oral cavity of the baby, the sensor is placed at the base of the tongue of the baby. Since it is located in the vicinity, it is difficult to detect the pressure on the tip of the tongue. Further, in the tongue movement monitoring device during the sucking motion of the baby, the sensor detects the external force received by the base because the base is distorted by the external force received during the sucking motion of the baby. That is, the tongue movement monitoring device during the sucking motion of the baby does not directly detect the pressure received from the tongue when the tongue movement is performed during the sucking motion of the baby. For these reasons, it has been difficult for the tongue movement monitoring device during the sucking motion of the baby to reliably monitor the state of the tongue movement during the sucking motion of the baby.

The present invention has been made in view of the above situations, and provides a tongue movement monitoring device during a sucking motion of an infant, which can more reliably monitor the state of the tongue movement during the sucking motion of the baby. That is the issue.

Next, the tongue movement monitoring device 1 and the method during the sucking motion of the baby according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 8.

The tongue movement monitoring device (hereinafter referred to as “infant tongue movement monitoring device”) 1 during the sucking movement of the baby is placed in the oral cavity of the baby to monitor the tongue movement during the sucking movement of the baby. Infants refer to babies up to a predetermined period after birth of mammals, including humans. The sucking motion of an infant refers to the motion of starting a tongue movement (slip-like motion) so that the ridge of the baby's tongue moves from the tip of the tongue to the base of the tongue when the nipple is sucked when collecting milk from the nipple. .. The sucking motion of a human baby is performed about twice a second. The sucking reflex of human infants disappears about 4 months after birth. There are individual differences in the pressure on the nipple (for example, the pressure on the tip of the tongue is extremely weak) and the timing of the peristaltic movement during the sucking motion of the baby. The sucking ability of the baby varies depending on the pressure on the nipple, the timing of the peristaltic movement, and the like.

Next, a specific configuration of the infant tongue movement monitoring device 1 will be described. In the following, the baby will be described as a human baby.
As shown in FIGS. 1 to 4, the baby tongue movement monitoring device 1 includes a base 2, a sensor 100, a control unit 3, and a display unit 4.

The base 2 is configured in the shape of a glove that can be worn on the hand of a worker (a person who monitors tongue movement in the sucking motion of an infant). The base 2 is made of, for example, a natural rubber latex material. Further, the base 2 can be configured in a finger cot shape that can be attached to a worker's finger.
The base 2 can be inserted into the oral cavity of an infant and can be formed in a columnar or finger shape close to the size of a nipple, or can be formed of an artificial nipple or the like. At this time, the base 2 is preferably made of an elastic material in consideration of being inserted into the oral cavity of the baby. Further, when the base 2 is formed in a columnar shape or the like, it is preferable that the base 2 has elasticity so as not to be easily crushed by the sucking motion of the baby in order to prevent the detection accuracy of the sensor 100 from deteriorating.

The sensor 100 is provided on the surface of the base 2. When the base 2 is configured like a glove, the sensor 100 is preferably provided on the surface of the back side (back side of the hand) of the tip such as the thumb part, the index finger part, or the little finger part. By arranging the sensor 100 in this way, it is possible to stimulate the palate of the baby on the ventral side of the finger (the side where the sensor 100 is not arranged) and induce the sucking reflex.
The sensor 100 is a pressure sensor, and detects the pressure received from the tongue (pressure due to muscle contraction) when the tongue is moved during the sucking motion of the baby in the baby's oral cavity. The sensor 100 is composed of a pressure-sensitive sensor (for example, a pressure-sensitive conductive elastomer) having a chip-like elasticity (for example, length: 2 mm, width: 2 mm, thickness: 0.75 mm). Information regarding the pressure of the infant's tongue movement detected by the sensor 100 is transmitted to the control unit 3.
In the baby tongue movement monitoring device 1, the sensor 100 (the surface of the sensor 100) is covered with a sheet member made of a polypropylene material in order to prevent the baby's tongue from coming into direct contact with the surface of the sensor 100.

The control unit 3 controls various operations of the baby tongue movement monitoring device 1. The control unit 3 includes a storage device for storing various information, a clock function (for example, a real-time clock), a communication circuit for communicating various information to the outside by wire or wireless, an A / D conversion circuit, and an MPU (Micro Processing Unit). ) Etc. are provided. The control unit 3 is electrically connected to the sensor 100 via a wire. The control unit 3 determines a predetermined condition (whether or not the baby's sucking motion is good) based on the information about the pressure of the baby's tongue movement detected by the sensor 100, and generates various information. do.
The control unit 3 can also be configured by a PC externally connected to the sensor 100.

The display unit 4 displays various information obtained by the baby tongue movement monitoring device 1. The display unit 4 displays, for example, the result of determination by the control unit 3 based on the information regarding the pressure of the infant's tongue movement detected by the sensor 100 or the information regarding the pressure of the infant's tongue movement detected by the sensor 100. ..
The display unit 4 is connected to the control unit 3 via a wired or wireless device. The display unit 4 is composed of, for example, a PC (Personal Computer) or a monitor connected to the outside.
The display unit 4 may be composed of a liquid crystal display unit 4 or a lamp unit provided on the base 2. With this configuration, the baby tongue movement monitoring device 1 can be configured as a portable device and can be used in each home.

The sensor 100 is arranged within a predetermined range on the surface of the base 2. A plurality of sensors 100 are arranged along the axis of the base 2 in the apical direction of the tongue of the baby (direction of insertion into the oral cavity of the baby) in a state where the base 2 is placed in the oral cavity of the baby (multi-stage). (Like) are arranged .
The sensor 100 includes a first sensor 101 and a second sensor 102. The first sensor 101 and the second sensor 102 are arranged side by side in the apical direction of the tongue of the baby with a predetermined interval so that the pressure during peristaltic movement can be detected. The first sensor 101 and the second sensor 102 are arranged so that the center distance between them is about 7 mm to 10 mm.
The first sensor 101 is arranged on the tongue base side of the baby (tip side of the base 2) of the second sensor 102, and detects the pressure of the baby's tongue movement on the tongue base side of the second sensor 102. The second sensor 102 detects the pressure of the tongue movement of the baby on the tongue tip side (base end side of the base 2) of the first sensor 101.

Next, in the infant tongue movement monitoring device 1, the operation of monitoring the tongue movement during the sucking movement of the baby will be described.

First, in the baby tongue movement monitoring device 1, the base 2 (sensor 100) is inserted into the baby's oral cavity so that the sensor 100 abuts on the upper surface (the surface on the upper jaw side of the tongue) of the baby's tongue. At this time, the alignment direction of the first sensor 101 and the second sensor 102 and the apical direction of the tongue are made to substantially coincide with each other.
In this way, when the base 2 is arranged, the sucking reflex is induced and the baby starts the sucking motion. In such a state, the first sensor 101 and the second sensor 102 detect the pressure received from the tongue when the tongue is moved during the sucking motion of the baby.
At this time, the sensor 100 (first sensor 101 and second sensor 102) is brought into contact with the surface of the baby's tongue for at least 1.5 to 2 seconds. However, in order to more accurately monitor the tongue movement during the sucking motion of the baby, the sensor 100 is kept in contact with the surface of the baby's tongue for a longer time (for example, about 5 to 10 seconds). Is preferable.

Next, a series of movements for determining the quality of the sucking movement of the baby in the baby tongue movement monitoring device 1 will be described with reference to FIG.

As shown in FIG. 5, in the infant tongue movement monitoring device 1, the sensor 100 (first sensor 101 and second sensor 102) detects the pressure received from the tongue when the tongue movement is performed during the sucking motion of the baby. (Step S1).
At this time, the information regarding the pressure of the infant's tongue movement detected by the sensor 100 is transmitted to the control unit 3 and displayed on the display unit 4.
Next, the process proceeds to step S2.

Next, based on the information regarding the pressure of the infant's tongue movement detected by the sensor 100, the control unit 3 determines whether the infant's sucking ability is good or bad (step S2).
At this time, the control unit 3 determines whether or not the baby is sucking with the required force from the information regarding the pressure of the baby's tongue movement detected by the sensor 100, or the baby is swaying at an appropriate timing. Determine if you are exercising.
When the control unit 3 determines whether the baby's sucking ability is good or bad, the operation is terminated.
In this way, the baby tongue movement monitoring device 1 performs an operation of monitoring the tongue movement during the sucking movement of the baby.

In the infant tongue movement monitoring device 1, during the operation of monitoring the tongue movement during the sucking movement of the baby, the sensor 100 receives the pressure received from the tongue when the tongue movement is performed during the sucking movement of the baby. It is constantly detected (for example, about 100 times per second), and every time the sensor 100 detects it, information regarding the pressure of the infant's tongue movement is transmitted to the control unit 3.

As described above, the base 2 is formed in the shape of a glove or a finger cot, and the sensor 100 is provided on the surface of the fingertip of the base 2, so that the tongue or the like is stimulated by the finger placed in the oral cavity of the baby. It becomes easy, and the sucking reflex can be easily promoted. Further, with this configuration, in addition to monitoring the tongue movement of the baby using the baby tongue movement monitoring device 1, the state of the tongue movement of the baby can be confirmed by tactile sensation (finger sensation). Can be done.

As described above, a plurality of sensors 100 are arranged side by side in the apical direction of the infant's tongue, and each sensor 100 directly receives the pressure received from the tongue when performing the tongue movement during the sucking motion of the infant. Since it is detected, it is possible to more reliably monitor the state of tongue movement during the sucking motion of the infant.

As described above, a plurality of sensors 100 are arranged side by side in the apical direction of the baby's tongue, and information on the pressure received from the tongue when the tongue movement during the sucking motion of the baby detected by the sensor 100 is obtained. Since the control unit 3 determines whether the baby's sucking ability is good or bad, it is possible to make the baby's sucking ability good or bad judgment more accurate.

Next, in the operation (step S2) in which the control unit 3 determines the quality of the sucking ability of the baby, FIG. 6 shows the operation of determining whether the baby is sucking with the required force. It will be explained using.

As shown in FIG. 6, the sensor 100 (first sensor 101 and second sensor 102) performed an operation (step S1) of detecting the pressure received from the tongue when the tongue was moved during the sucking operation of the infant. After that, the control unit 3 performs an operation of selecting the first evaluation value P1 and the second evaluation value P2, respectively (step S11).
The first evaluation value P1 and the second evaluation value P2 are values to be evaluated when the control unit 3 determines the quality of the sucking ability of the baby, and the first sensor 101 or the first sensor 101 or the second evaluation value P2 in one sucking cycle. The peak value of the pressure of the infant's tongue movement detected by the second sensor 102 is adopted.
The peak value of the pressure of the infant's tongue movement detected by the sensor 100 (first sensor 101) arranged on the tongue base side of the infant is adopted as the first evaluation value P1, and the second evaluation value P2 is the infant's tongue movement. The peak value of the pressure of the infant's tongue movement detected by the sensor 100 (second sensor 102) arranged on the tongue tip side is adopted.
The pressure of the tongue movement during the sucking motion of the baby is generally higher on the tongue base side than on the tongue tip.
In this way, the control unit 3 performs an operation of selecting the first evaluation value P1 and the second evaluation value P2, respectively.
After the control unit 3 performs an operation of selecting the first evaluation value P1 and the second evaluation value P2, the process proceeds to step S12.

Next, the control unit 3 determines whether or not “second evaluation value P2 / first evaluation value P1 ≧ predetermined ratio Ph” (step S12).
The predetermined ratio Ph is set to a value of about 40% to 50%. The predetermined ratio Ph can be arbitrarily set according to the state of the detection target, the intended use, etc., and is used to accurately determine whether or not the baby is sucking with the required force. It is preferably set to 50%.
If the control unit 3 determines that "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph", the process proceeds to step S13.
If the control unit 3 determines that “second evaluation value P2 / first evaluation value P1 ≧ predetermined ratio Ph” (when the pressure on the apical side of the tongue is too weak), the process proceeds to step S14.

When the control unit 3 determines in step S12 that "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph", the baby's sucking power is strong and the baby's sucking ability is good. The control unit 3 determines (step S13).
At this time, the display unit 4 displays that the baby's sucking ability is good (for example, a “◯” mark is displayed).
If the control unit 3 has "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph" in step S12, it should be noted that, within a predetermined time, a plurality of times or a plurality of times continuously (for example, three times in 3 seconds, Alternatively, the control unit 3 may determine that the sucking power of the baby is strong and the sucking ability of the baby is good only when the judgment is made twice continuously in 3 seconds.

When the control unit 3 determines in step S12 that "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph", it is determined that the baby's sucking power is weak and the baby's sucking ability is poor. The control unit 3 determines (step S14).
At this time, the display unit 4 displays that the baby's sucking ability is poor (for example, an "x" mark is displayed).
As described above, the control unit 3 determines whether or not the baby is sucking with the necessary force.

As described above, since the control unit 3 determines whether or not the baby is sucking with the necessary force, the control unit 3 determines whether or not the baby is performing a specific movement when sucking. , It is possible to make the judgment of the quality of the sucking ability of the baby more accurate.

As described above, when the control unit 3 determines that the relationship of the second evaluation value P2 / first evaluation value P1 ≧ predetermined ratio Ph is satisfied, the baby is sucking with the necessary force. Since the determination to that effect is made, it is possible to determine whether or not the baby's sucking ability is good or bad, and to make the judgment as to whether or not the baby's sucking ability is good or bad.

Next, in the operation (step S2) in which the control unit 3 determines whether or not the baby's sucking ability is good or bad, FIG. 7 shows the operation of determining whether or not the baby is performing a peristaltic-like movement at an appropriate timing. It will be explained using.

As shown in FIG. 7, the sensor 100 (first sensor 101 and second sensor 102) performed an operation (step S1) of detecting the pressure received from the tongue when the tongue movement was performed during the sucking operation of the infant. After that, the control unit 3 performs an operation of selecting the first evaluation value T1 and the second evaluation value T2, respectively (step S21).
The first evaluation value T1 and the second evaluation value T2 are values to be evaluated when the control unit 3 determines the quality of the sucking ability of the infant, and the first sensor 101 or the first sensor 101 or the second evaluation value T2 in one sucking cycle. The time to reach the peak value of the pressure of the infant's tongue movement detected by the second sensor 102 is adopted.
For the first evaluation value T1, the time to reach the peak value of the pressure of the infant's tongue movement detected by the sensor 100 (first sensor 101) arranged on the tongue base side of the infant is adopted, and the second evaluation value T2 is The time to reach the peak value of the pressure of the infant's tongue movement detected by the sensor 100 (second sensor 102) arranged on the tongue tip side of the infant is adopted.
After the control unit 3 performs an operation of selecting the first evaluation value T1 and the second evaluation value T2, the process proceeds to step S22.

Next, the control unit 3 determines whether or not "time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th" (step S22).
The predetermined ratio Th is set to a value of about 6% to 8%. The predetermined ratio Th can be arbitrarily set according to the intended use, etc., and is preferably 8% in order to accurately determine whether or not the baby is performing peristaltic movement at an appropriate timing. Set.
If the control unit 3 determines that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", the process proceeds to step S23.
When the control unit 3 determines that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th" (the movement timings of the tip of the tongue and the base of the tongue are too close to each other, and the peristaltic movement occurs. If not completed), the process proceeds to step S24.
The time difference between the first evaluation value T1 and the second evaluation value T2 is a value obtained by subtracting the second evaluation value T2 from the first evaluation value T1. It indicates that the movement is moving from the tip of the tongue to the base of the tongue. When the baby is sucking normally, the time difference between the first evaluation value T1 and the second evaluation value T2 shows at least a positive value.
When the time difference between the first evaluation value T1 and the second evaluation value T2 is calculated, if the value obtained by subtracting the second evaluation value T2 from the first evaluation value T1 is a negative value, the baby sucks. It indicates that the tongue movement during the sucking motion is moving from the tongue base side to the tongue tip side, and it is considered that the baby is not performing the sucking motion normally. (Ii) It is determined that the time difference from the evaluation value T2 / cycle ≧ predetermined ratio Th ”is not satisfied (the sucking operation is not performed at an appropriate timing). Further, when the time difference between the first evaluation value T1 and the second evaluation value T2 is calculated, if the value obtained by subtracting the second evaluation value T2 from the first evaluation value T1 is a negative value, the step is taken. It is also possible to shift to S1 and repeat the operation until the value obtained by subtracting the second evaluation value T2 from the first evaluation value T1 becomes a positive value.

When the control unit 3 determines in step S22 that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", the baby performs a peristaltic movement at an appropriate timing. The control unit 3 determines that the sucking ability of the baby is good (step S23).
At this time, the display unit 4 displays that the baby's sucking ability is good.

If the control unit 3 determines in step S22 that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", the baby performs a peristaltic movement at an appropriate timing. The control unit 3 determines that the sucking ability of the baby is poor (step S24).
At this time, the display unit 4 displays that the baby's sucking ability is poor.
Further, when the time difference between the first evaluation value T1 and the second evaluation value T2 is calculated in step S22, the value obtained by subtracting the second evaluation value T2 from the first evaluation value T1 is a negative value. Can also be configured to display on the display unit 4 that the determination is impossible.
If the control unit 3 in step S22 is "time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", a plurality of times or a plurality of times continuously (for example, 3 seconds) within a predetermined time. The control unit 3 determines that the baby is performing peristaltic movement at an appropriate timing and the baby's sucking ability is good only when the judgment is made 3 times or 2 times in 3 seconds in a row. It can also be configured.

As described above, since the control unit 3 determines whether or not the baby is performing peristaltic-like movement at an appropriate timing, the control unit 3 determines whether or not the baby is performing a specific movement during sucking. It is possible to make the judgment of the quality of the sucking ability of the baby more accurate.

As described above, when the control unit 3 determines that the relationship of time difference / cycle ≧ predetermined ratio Th between the first evaluation value T1 and the second evaluation value T2 is satisfied, the baby moves in a peristaltic manner at an appropriate timing. Since it is determined that the baby is sucking, it is possible to judge the quality of the baby's sucking ability more concretely and to make the judgment of the baby's sucking ability more accurate.

In the baby tongue movement monitoring device 1, when the control unit 3 determines in step S12 that the control unit 3 is "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph", or in step S22. When the control unit 3 determines that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", the control unit 3 determines that the sucking ability of the baby is good. It can also be configured to be used.
With this configuration, it is possible to determine the quality of the sucking ability of the baby under relatively loose conditions.

In the baby tongue movement monitoring device 1, when the control unit 3 determines in step S12 that the control unit 3 has "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph", and in step S22. When the control unit 3 determines that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", the control unit 3 determines that the sucking ability of the baby is good. It can also be configured to be used.
With such a configuration, it is possible to determine the quality of the sucking ability of the baby under relatively severe conditions and to reliably determine the quality of the sucking ability of the baby.

As shown in FIG. 8, the baby tongue movement monitoring device 1 may be configured to include an operation unit 5.
The operation unit 5 enables the start and end of various operations of the baby tongue movement monitoring device 1 and the setting of various operations by operating the operation unit 5, and is composed of switches, a touch panel, and the like. Tongue. For example, the baby tongue movement monitoring device 1 is configured to start or end the operation of monitoring the sucking motion of the baby by operating the operation unit 5.

Further, the baby tongue movement monitoring device 1 may be configured to include a notification unit 6.
The notification unit 6 notifies various information obtained by the baby tongue movement monitoring device 1 (sensor 100). The notification unit 6 is provided with a speaker, a lamp, or the like provided on the base 2, and notifies various information by emitting sound from the speaker, turning on or off the lamp, and the like. For example, instead of displaying on the display unit 4 that the baby's sucking ability is good, when the control unit 3 determines that the baby's sucking ability is good, a buzzer sound is emitted from the speaker. , Or the lamp is turned on or off.

Next, the baby tongue movement monitoring device 1 and the method according to the second embodiment of the present invention will be described with reference to FIGS. 9 to 11. The description of the baby tongue movement monitoring device 1 and the method according to the second embodiment of the present invention is appropriately the same as the description of the baby tongue movement monitoring device 1 and the method according to the first embodiment of the present invention. The explanation will be focused on the different parts.

As shown in FIG. 9, the sensor 200 is composed of three or more sensors 200 (first sensor 201, second sensor 202, third sensor 203, fourth sensor 204, and fifth sensor 205). .. The first sensor 201, the second sensor 202, the third sensor 203, the fourth sensor 204, and the fifth sensor 205 are spaced apart from each other so as to be able to detect the pressure during peristaltic movement, and the base of the tongue of the baby. They are arranged in order in the sharp direction. The first sensor 201, the second sensor 202, the third sensor 203, the fourth sensor 204, and the fifth sensor 205 are arranged so that the center distance between them is about 5 mm to 7 mm.

Next, in the operation (step S2) in which the control unit 3 determines the quality of the sucking ability of the baby, FIG. 10 shows an operation of determining whether the baby is sucking with the required force. It will be explained using.

As shown in FIG. 10, after the sensor 200 performs an operation (step S1) of detecting the pressure received from the tongue when the tongue moves during the sucking operation of the baby, the control unit 3 is arbitrarily set. The first evaluation area and the second evaluation area are selected from the plurality of areas (step S10).

A single sensor 200 or a plurality (two) sensors 200 are arranged in each of a plurality of arbitrarily set areas. Area A where the first sensor 201 and the second sensor 202 are arranged, area B where the second sensor 202 and the third sensor 203 are arranged, and an area where the third sensor 203 and the fourth sensor 204 are arranged. Is set in advance as Area C, and the area where the fourth sensor 204 and the fifth sensor 205 are arranged is set as Area D.

At this time, the control unit 3 has each sensor arranged in each area arbitrarily set based on the information regarding the pressure of the infant's tongue movement detected by the sensor 200 within a predetermined time (for example, 3 seconds). The total value of the values related to the pressure of the infant's tongue movement for each detection timing detected by the 200 is calculated.
That is, the control unit 3 calculates the total value of the infant's tongue movement pressure for each detection timing detected by the first sensor 201 and the second sensor 202 in the area A within a predetermined time, and the second sensor 2 in the area B. The total value of the infant's tongue movement pressure for each detection timing detected by the sensor 202 and the third sensor 203 is calculated, and the infant's for each detection timing detected by the third sensor 203 and the fourth sensor 204 in area C, respectively. The total value of the tongue movement pressure is calculated, and the total value of the infant's tongue movement pressure for each detection timing detected by the fourth sensor 204 and the fifth sensor 205 in the area D is calculated. In this way, the total value of the pressure of the infant's tongue movement for each detection timing detected by the plurality of sensors 200 adjacent to each other in the predetermined area is calculated.

Then, the control unit 3 has a predetermined time (for example, 3 seconds) based on the total value of the pressure of the infant's tongue movement for each detection timing within the predetermined time among the plurality of areas (areas A to D). The top two areas are selected in descending order of the average value in.
Then, among the areas A to D selected by the control unit 3, the two areas from the highest average value of the infant's tongue movement pressure (descending order) are adopted as the first evaluation area or the second evaluation area. Will be done. In the first evaluation area, the area located on the tongue base side of the baby out of the two selected areas is adopted, and in the second evaluation area, the tongue tip of the baby out of the two selected areas. The area placed on the side is adopted.

For example, when the control unit 3 has the highest average value within a predetermined time based on the total value of the infant's tongue movement pressure at each detection timing in area A and the next highest in area B, The top two areas are selected as Area A and Area B. Since the area A is arranged closer to the tongue base of the baby than the area B, the control unit 3 adopts the area A as the first evaluation area and the area B as the second evaluation area.
In this way, the control unit 3 selects the first evaluation area and the second evaluation area from a plurality of arbitrarily set areas.
When the control unit 3 finishes the step of selecting the first evaluation area and the second evaluation area from a plurality of arbitrarily set areas, the control unit 3 proceeds to step S11.

Next, the operation in which the control unit 3 selects the first evaluation value P1 and the second evaluation value P2 in step S11 at this time will be described.

For the first evaluation value P1, the peak value in the total value of the pressure of the baby's tongue movement for each detection timing in the first evaluation area (the area arranged on the tongue base side of the baby) is adopted, and the second evaluation value P2 is set. Is adopted as the peak value in the total value of the pressure of the infant's tongue movement for each detection timing in the second evaluation area (the area arranged on the tongue tip side of the infant).
In this way, the control unit 3 performs an operation of selecting the first evaluation value P1 and the second evaluation value P2, respectively.
After the control unit 3 performs an operation of selecting the first evaluation value P1 and the second evaluation value P2, the process proceeds to step S12.

Next, the control unit 3 determines whether or not “second evaluation value P2 / first evaluation value P1 ≧ predetermined ratio Ph” (step S12).
If the control unit 3 determines that "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph", the process proceeds to step S13.
If the control unit 3 determines that “second evaluation value P2 / first evaluation value P1 ≧ predetermined ratio Ph” (when the pressure on the apical side of the tongue is too weak), the process proceeds to step S14.

When the control unit 3 determines in step S12 that "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph", the baby's sucking power is strong and the baby's sucking ability is good. The control unit 3 determines (step S13).
At this time, the display unit 4 displays that the baby's sucking ability is good (for example, a “◯” mark is displayed).

When the control unit 3 determines in step S12 that "second evaluation value P2 / first evaluation value P1 ≥ predetermined ratio Ph", it is determined that the baby's sucking power is weak and the baby's sucking ability is poor. The control unit 3 determines (step S14).
At this time, the display unit 4 displays that the baby's sucking ability is poor (for example, an "x" mark is displayed).
As described above, the control unit 3 determines whether or not the baby is sucking with the necessary force.

As described above, the sensors 200 are composed of three or more sensors 200 and are arranged in order in the apical direction of the infant's tongue, and each sensor 200 is the tongue during the sucking operation of the infant. By detecting the pressure received from the tongue when exercising, it is possible to more reliably monitor the state of tongue movement during the sucking motion of the infant.

As described above, the control unit 3 calculates the total value of the pressure of the infant's tongue movement for each detection timing within the predetermined time among the plurality of areas, and the infant's tongue for each detection timing within the predetermined time. Based on the total value of exercise pressure, the top two areas are selected in descending order of average value within a predetermined time, and the top two areas are selected as the first evaluation area or the second evaluation area, and the first evaluation is performed. As the value P1, the peak value in the total value of the pressure of the infant's tongue movement for each detection timing in the area (first evaluation area) arranged on the tongue base side of the infant is adopted, and as the second evaluation value P2, the peak value is adopted. Since the peak value in the total value of the infant's tongue movement pressure for each detection timing in the area arranged on the tongue tip side of the infant (second evaluation area) is adopted, the sensor 200 is used in a more detailed and wide range of the infant. The control unit detects the pressure received from the tongue when performing the tongue movement during the sucking motion, and determines the quality of the sucking ability of the infant based on the information regarding the pressure received from the tongue when the tongue movement is performed. 3 can be done.

Next, in the operation (step S2) in which the control unit 3 determines the quality of the sucking ability of the baby, FIG. 11 shows the operation of determining the quality of the baby's peristaltic movement at an appropriate timing. It will be explained using.

As shown in FIG. 11, after the sensor 200 performs an operation (step S1) of detecting the pressure received from the tongue when the tongue moves during the sucking operation of the baby, the control unit 3 is arbitrarily set. The first evaluation area and the second evaluation area are selected from the plurality of areas (step S20).

A single sensor 200 or a plurality (two) sensors 200 are arranged in each of a plurality of arbitrarily set areas. Area A where the first sensor 201 and the second sensor 202 are arranged, area B where the second sensor 202 and the third sensor 203 are arranged, and an area where the third sensor 203 and the fourth sensor 204 are arranged. Is set in advance as Area C, and the area where the fourth sensor 204 and the fifth sensor 205 are arranged is set as Area D.

At this time, the control unit 3 has each sensor arranged in each area arbitrarily set based on the information regarding the pressure of the infant's tongue movement detected by the sensor 200 within a predetermined time (for example, 3 seconds). The total value of the values related to the pressure of the infant's tongue movement for each detection timing detected by the 200 is calculated.
That is, the control unit 3 calculates the total value of the infant's tongue movement pressure for each detection timing detected by the first sensor 201 and the second sensor 202 in the area A within a predetermined time, and the second sensor 2 in the area B. The total value of the infant's tongue movement pressure for each detection timing detected by the sensor 202 and the third sensor 203 is calculated, and the infant's for each detection timing detected by the third sensor 203 and the fourth sensor 204 in area C, respectively. The total value of the tongue movement pressure is calculated, and the total value of the infant's tongue movement pressure for each detection timing detected by the fourth sensor 204 and the fifth sensor 205 in the area D is calculated. In this way, the total value of the pressure of the infant's tongue movement for each detection timing detected by the plurality of sensors 200 adjacent to each other in the predetermined area is calculated.

Then, the control unit 3 has a plurality of areas (areas A to D) in descending order of the average value within the predetermined time based on the total value of the pressure of the infant's tongue movement for each detection timing within the predetermined time. Select the top two areas in (descending order).
Then, among the areas A to D selected by the control unit 3, the two areas from the highest average value of the infant's tongue movement pressure (descending order) are adopted as the first evaluation area or the second evaluation area. Will be done. In the first evaluation area, the area located on the tongue base side of the baby out of the two selected areas is adopted, and in the second evaluation area, the tongue tip of the baby out of the two selected areas. The area placed on the side is adopted.

For example, the control unit 3 has the highest average value in the predetermined time in the area A and the next highest in the area B based on the total value of the tongue movement pressure of the baby at each detection timing in the predetermined time. If, the upper two areas are selected as area A and area B. Since the area A is arranged closer to the tongue base of the baby than the area B, the control unit 3 adopts the area A as the first evaluation area and the area B as the second evaluation area.
In this way, the control unit 3 selects the first evaluation area and the second evaluation area from a plurality of arbitrarily set areas.
When the control unit 3 finishes the step of selecting the first evaluation area and the second evaluation area from a plurality of arbitrarily set areas, the control unit 3 proceeds to step S21.

Next, the operation in which the control unit 3 selects the first evaluation value T1 and the second evaluation value T2 in step S21 at this time will be described.

The control unit 3 ranks higher in the order of the highest average value of the tongue movement pressure of the baby detected by the sensors 200 arranged in the first evaluation area and the second evaluation area (descending order) within a predetermined time. Select two sensors 200.
Then, the time to reach the peak value of the pressure of the tongue movement of the infant within the predetermined time detected by the two sensors 200 arranged in the first evaluation area and the second evaluation area selected by the control unit 3 is the first. It is adopted as the evaluation value T1 or the second evaluation value T2. For the first evaluation value T1, the time to reach the peak value of the pressure of the infant's tongue movement within a predetermined time detected by the sensor 200 arranged on the tongue base side of the infant among the two selected sensors 200 is adopted. The second evaluation value T2 is the time required to reach the peak value of the pressure of the infant's tongue movement within a predetermined time detected by the sensor 200 arranged on the tongue tip side of the infant among the two selected sensors 200. Is adopted.

For example, the control unit 3 has the first sensor 201, the second sensor 201 arranged in the area A (first evaluation area) and the area B (second evaluation area) regarding the average value of the tongue movement pressure of the infant within a predetermined time. When the highest sensor 202 and the third sensor 203 are the first sensor 201 and the next highest sensor 202 is the second sensor 202, the upper two sensors 200 (first sensor 201 and second sensor 202) are used. ) Is selected, and the time to reach the peak value of the tongue movement pressure of the infant within the predetermined time detected by the two sensors 200 (first sensor 201 and second sensor 202) is the first evaluation value T1 or the second. Select as the evaluation value T2. Then, since the first sensor 201 is arranged closer to the tongue base of the infant than the second sensor 202, the control unit 3 sets the peak value of the pressure of the infant's tongue movement within the predetermined time detected by the first sensor 201. The time to reach is adopted as the first evaluation value T1, and the time to reach the peak value of the pressure of the tongue movement of the infant within the predetermined time detected by the second sensor 202 is adopted as the second evaluation value T2.
In this way, the control unit 3 performs an operation of selecting the first evaluation value T1 and the second evaluation value T2, respectively.
After the control unit 3 performs an operation of selecting the first evaluation value T1 and the second evaluation value T2, the process proceeds to step S22.

Next, the control unit 3 determines whether or not "time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th" (step S22).
If the control unit 3 determines that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", the process proceeds to step S23.
When the control unit 3 determines that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th" (the movement timings of the tip of the tongue and the base of the tongue are too close to each other, and the peristaltic movement occurs. If not completed), the process proceeds to step S24.

When the control unit 3 determines in step S22 that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", the baby performs a peristaltic movement at an appropriate timing. The control unit 3 determines that the sucking ability of the baby is good (step S23).
At this time, the display unit 4 displays that the baby's sucking ability is good.

If the control unit 3 determines in step S22 that "the time difference / cycle between the first evaluation value T1 and the second evaluation value T2 ≥ a predetermined ratio Th", the baby performs a peristaltic movement at an appropriate timing. The control unit 3 determines that the sucking ability of the baby is poor (step S24).
At this time, the display unit 4 displays that the baby's sucking ability is poor.
As described above, the control unit 3 determines whether or not the baby is performing peristaltic-like movement at an appropriate timing.

As described above, the control unit 3 calculates the total value of the pressure of the infant's tongue movement for each detection timing within the predetermined time among the plurality of areas, and the infant's tongue for each detection timing within the predetermined time. Based on the total value of exercise pressure, the top two areas are selected in descending order of average value within a predetermined time, and the top two areas are selected as the first evaluation area or the second evaluation area, and the first evaluation is performed. For the value T1, the time to reach the peak value of the pressure of the infant's tongue movement within a predetermined time detected by the sensor 200 arranged on the tongue base side of the infant among the two sensors 200 is adopted, and the second evaluation is performed. As the value T2, the time to reach the peak value of the pressure of the infant's tongue movement within a predetermined time detected by the sensor 200 arranged on the tongue tip side of the infant among the two sensors 200 is adopted. In a detailed and wide range, the sensor 200 detects the pressure received from the tongue when the infant's tongue movement is performed during the sucking motion of the baby, and based on the information on the pressure received from the tongue when the tongue movement is performed, the infant The control unit 3 can determine the quality of the sucking ability of the above.

When the arrangement distance of the adjacent sensors 200 is short as in the present embodiment, it is desirable to do as follows. That is, when the control unit 3 selects the first evaluation area and the second evaluation area, if the descending order of the adjacent areas is continuous, the first evaluation area is adopted and the second evaluation area is not adopted. By advancing the next order in the order after that, it is possible to prevent the baby's tongue movement from being monitored in a narrow range of the baby's tongue, and the baby's sucking ability. It is possible to make the quality judgment of the above more accurate.
When the arrangement distance of the adjacent sensors 200 is long (for example, 10 mm or more), the sensors having continuous descending order may be adopted.

The number of sensors 200 arranged in the plurality of areas is not limited to two, and may be one or three or more. For example, the area where the first sensor 201, the second sensor 202, and the third sensor 203 are arranged is the area A, and the area where the second sensor 202, the third sensor 203, and the fourth sensor 204 are arranged is the area B. The area where the third sensor 203, the fourth sensor 204, and the fifth sensor 205 are arranged can also be set as the area C. Further, for example, the area where the first sensor 201 is arranged is the area A, the area where the second sensor 202, the third sensor 203, and the fourth sensor 204 are arranged is the area B, and the area where the fifth sensor 205 is arranged. It can also be set as area C.
In addition, the area range setting (sensor 200 set to be located in each area) is the size of the baby's oral cavity, the size of the baby's tongue, the specifications of the base 2, the specifications of the sensor 200, or the sensor. It can be changed as appropriate depending on the arrangement location of the 200 and the like.

In step S10 or step S20, when the control unit 3 selects the first evaluation area and the second evaluation area, if the descending order of the adjacent areas is continuous, the one in the previous order (higher value) is adopted. However, it is also possible to move up and adopt the next order in the subsequent order without adopting the one in the later order.

For example, of Areas A to D, the average value of the tongue movement pressure of the infant in the area within a predetermined time is the highest in Area A, the highest in Area B next to Area A, and the highest in Area C next to Area B. The control unit 3 selects that the area A is the first in the area A to D regarding the average value of the pressure of the infant's tongue movement within a predetermined time, and the area is close to the area A. Instead of selecting area B as the second, move it up and select area C as the second.

In this way, when the control unit 3 selects the first evaluation area and the second evaluation area, if the descending order of the adjacent areas is continuous, the first evaluation area is adopted and the second evaluation area is adopted. By advancing the next order in the following order without doing so, it is possible to prevent the baby's tongue movement from being monitored in a narrow range of the baby's tongue, and to prevent the baby from sucking. It is possible to make the judgment of the quality of the baby ability more accurate.

In step S21, when the control unit 3 selects the first evaluation value T1 and the second evaluation value T2 in determining whether or not the baby is performing peristaltic movement at an appropriate timing, the sensors in close proximity to each other. When the descending order of 200 is continuous, the one in the first order (higher value) is adopted, and the one in the next order after that is not adopted, but the one in the next order is adopted. It can also be.

For example, area A is selected as the first evaluation area, area B is selected as the second evaluation area, and within a predetermined time detected by the first sensor 201, the second sensor 202, and the third sensor 203 arranged in the area A and the area B. Control when the first sensor 201 is the highest, the second sensor 202 is the second highest after the first sensor 201, and the third sensor 203 is the second highest after the second sensor 202, regarding the average value of the tongue movement pressure of the infant in Part 3 selects that the first sensor 201 is the first among the sensors 200 arranged in the first evaluation area and the second evaluation area with respect to the average value of the tongue movement pressure of the infant within a predetermined time. Since it is close to the first sensor 201, the second sensor 202 is not selected as the second sensor, but is advanced and the third sensor 203 is selected as the second sensor. Then, the time to reach the peak value of the pressure of the infant's tongue movement within the predetermined time detected by the first sensor 201 is adopted as the first evaluation value T1, and the infant's tongue movement within the predetermined time detected by the third sensor 203 is adopted. The time to reach the peak value of the pressure of is adopted as the second evaluation value T2.

In this way, when the control unit 3 selects the first evaluation value T1 and the second evaluation value T2, if the descending order of the adjacent sensors 200 is continuous, the one in the previous order (higher value) is selected. By adopting and adopting the one in the next order in the subsequent order without adopting the one in the later order, the baby's tongue movement is monitored in a narrow range of the infant's tongue. It is possible to prevent the baby from becoming a baby and make the judgment of the quality of the sucking ability of the baby more accurate.

The sensors in the left column and the sensors in the right column are arranged so that the center distance between them is about 5 mm to 7 mm.

In the infant tongue movement monitoring device 1, after the sensor 300 performs an operation (step S1) of detecting the pressure received from the tongue when the tongue movement is performed during the sucking operation of the baby, the control unit 3 performs the first evaluation. An operation of selecting an area and a second evaluation area is performed (step S11 or step S21).
At this time, when the control unit 3 selects the first evaluation area and the second evaluation area in step S11 or step S21, the infant detected by the sensor 300 arranged in a plurality of arbitrarily set areas. The operation of calculating the total value of the pressure of the tongue movement will be described. In the present embodiment, a plurality of arbitrarily set areas are set in the apical direction of the baby's tongue, and a plurality (two) of sensors 300 are arranged in the left-right direction of the baby's tongue.

A single sensor 300 or a plurality (four) sensors 300 are arranged in each of a plurality of arbitrarily set areas. Area A is the area where the first sensor 301, the second sensor 302, the sixth sensor 306, and the seventh sensor 307 are arranged, and the second sensor 302, the third sensor 303, the seventh sensor 307, and the eighth sensor 308 are located. Area B is the area where the third sensor 303, the fourth sensor 304, the eighth sensor 308, and the ninth sensor 309 are arranged, and the area C where the third sensor 303, the fourth sensor 304, the eighth sensor 308, and the ninth sensor 309 are arranged. The area where the ninth sensor 309 and the tenth sensor 310 are arranged is set as an area D and is set in advance.
That is, the control unit 3 controls the pressure of the infant's tongue movement at each detection timing detected by the first sensor 301, the second sensor 302, the sixth sensor 306, and the seventh sensor 307 in the area A within a predetermined time. The total value was calculated, and the total value of the infant's tongue movement pressure at each detection timing detected by the second sensor 302, the third sensor 303, the seventh sensor 307, and the eighth sensor 308 in the area B was calculated. The total value of the infant's tongue movement pressure for each detection timing detected by the third sensor 303, the fourth sensor 304, the eighth sensor 308, and the ninth sensor 309 in the area C is calculated, and the fourth sensor in the area D. The total value of the pressure of the infant's tongue movement for each detection timing detected by 304, the fifth sensor 305, the ninth sensor 309, and the tenth sensor 310 is calculated.
In this way, the total value of the pressure of the tongue movement of the baby within the predetermined time detected by the plurality of adjacent sensors 300 is calculated.

Sensors in the same row when the control unit 3 selects the first evaluation value T1 and the second evaluation value T2 in step S21 in determining whether or not the baby is performing peristaltic movement at an appropriate timing. When the descending order of 300 is continuous, the one in the first order (higher value) is adopted, and the one in the next order after that is not adopted, but the one in the next order is adopted.

For example, the first sensor 301, the second sensor 302, the third sensor 303, the sixth sensor 306, in which the area A is selected as the first evaluation area and the area B is selected as the second evaluation area and are arranged in the area A and the area B, Regarding the average value of the tongue movement pressure of the infant within the predetermined time detected by the seventh sensor 307 and the eighth sensor 308, the first sensor 301 has the highest value, the sixth sensor 306 has the highest value next to the first sensor 301, and the third sensor 306 has the highest value. When the second sensor 302 is the second highest after the sixth sensor 306, the control unit 3 is the average value of the pressure of the infant's tongue movement within a predetermined time among the sensors 300 arranged in the first evaluation area and the second evaluation area. The first sensor 301 is selected as the first sensor, the sixth sensor 306 in the same row as the first sensor 301 is not selected as the second sensor, and the second sensor 302 is selected as the second sensor. And the first sensor 3
The time to reach the peak value of the infant's tongue movement pressure detected by 01 is adopted as the first evaluation value T1, and the time to reach the peak value of the infant's tongue movement pressure detected by the second sensor 302 is the second. It is adopted as the evaluation value T2.

As described above, since a plurality of sensors 300 are arranged side by side in the apical direction of the infant's tongue and a plurality of sensors 300 are arranged side by side in the left-right direction of the infant's tongue, a more detailed and wide range is provided.

The control unit 3 can determine the quality of the above.
Since a plurality of arbitrarily set areas are set in the apical direction of the infant's tongue and a plurality of areas are set in the left-right direction of the infant's tongue, the sensor 300 can be used for sucking the infant in a more detailed and wide range. The control unit 3 detects the pressure received from the tongue when performing the tongue movement during the tongue movement, and determines the quality of the sucking ability of the infant based on the information regarding the pressure received from the tongue when the tongue movement is performed.
