Description

  The present invention relates to a biological information detection device that detects information on a living body (for example, a human body, an animal such as a pet), a bed device on which the sensor unit is mounted, and a seating device on which the sensor unit is mounted.

  Patent Document 1 discloses a biological information detection panel and a biological information detector.

This panel is for detecting biological information, and a laying plate portion formed of a metal (aluminum or aluminum alloy) having a predetermined bending rigidity and disposed on the lower side of the user, And a strain detection sensor which is disposed on the floor plate portion and detects a bending strain of the floor plate portion. A strain detection sensor detects a change in bending strain of the laying plate portion generated based on the user's biological activity.
JP 2006-43445 A

  According to the above technique, a base metal plate is essential. For this reason, it may affect the user's sleeping comfort, sitting comfort, etc., and may cause a great sense of incongruity.

  As a method for solving such a problem, for example, if a detection device that does not require the use of a laying plate such as an organic piezoelectric film sensor such as PVDF and the sensor itself is flexible, the sense of incongruity in comfort and the like is reduced. .

  However, when such a sensor is mounted on or inside the bed mattress, the mattress may be greatly deformed depending on the movement / state of the user, so that the film-shaped sensor may be greatly deformed or wrinkled. And the film may break. Further, it is necessary to connect a signal line for transmitting a sensor output signal to the sensor. However, stress may concentrate on the connection portion, and the connection portion may be broken.

  In order to solve this problem, it is conceivable to mount a sensor under the mattress. As a result, the rigidity of the member (bed casing / floor) on which the mattress is placed can suppress excessive deformation of the sensor and application of excessive stress to the sensor, but the deformation of the sensor is suppressed too much. Since the distance between the user and the sensor is increased, the sensor output signal that has detected vibration caused by the heartbeat or respiration of the user, which is originally minute, is further attenuated, and the biological signal cannot be captured and detected.

  In addition, a method of adhering the sensor film and the signal line to the surrounding elastic body may be used to fix the sensor and the signal line. However, depending on the movement and state of the user, stress concentration may occur on the adhered part. This may cause problems such as film breakage and signal line breakage.

  The present invention has been made in view of the above circumstances, and is advantageous in reducing or eliminating the sense of discomfort felt by the living body of a user or the like when detecting biological information, and has high detection sensitivity of biological information and durability. It is an object of the present invention to provide a biological information detection body having a high level, and a bed apparatus and a seating apparatus that detect biological information with high detection sensitivity and high durability.

It is in having.

  The biological information detector according to claim 2 that solves the above-described problem is characterized in that, in claim 1, at least a part of the signal line excluding the vicinity of the mold part is formed of the soft member and the pressure transmission member. It is fixed to at least one of them.

A seating section main body on which the living body is seated, having the soft member in which the detection section of the biological information detection body is disposed;
It is in having.

  The biological information detector according to claim 1 configured as described above exhibits the following operational effects because of the above configuration. First, since a thin-film-like member is employed as a detection unit that detects pressure fluctuations, the user does not feel uncomfortable. And since the stress added to a connection part can be reduced by providing the mold part formed from a hard material in the connection part of a detection part and a signal wire | line, durability is improving. In addition, since a pressure transmission member having a shape that can be brought into close contact with the shape of the detection portion and the vicinity of the detection portion of the mold portion (for example, a shape that is deformed by close contact with elasticity or a complementary shape) is provided, Even a slight pressure change that occurs can be efficiently transmitted to the detection unit, and high sensitivity can be realized. Even if deformation due to a pressure change from the outside occurs, the pressure transmission member is used for the detection unit and the mold unit. Since the same deformation occurs in close contact with both the vicinity of the detection unit, there is no possibility that a large stress is locally applied to the detection unit and the connection part of the detection unit and the signal line. Furthermore, since the relative movement between the pressure transmission member and the surface of the detection unit is possible, even if the pressure transmission member is largely deformed due to deformation caused by a large external pressure application, a large stress is applied in the direction in which the detection unit spreads. There is no participation. That is, even if the pressure transmission member is greatly deformed and greatly differs from the degree of deformation of the detection unit, the stress in the displacement direction (the direction in which the detection unit spreads) is not transmitted as it is between them. As the pressure transmission member is deformed, the detector is not greatly deformed.

  In the biological information detector according to claim 2 configured as described above, the signal line is fixed and the movement of the signal line is restricted by restricting the movement of the signal line, and the signal line is connected to the mold part. It is possible to suppress the occurrence of defects such as breakage in the parts to be performed. When the signal line is fixed, an excessive stress is applied to the portion where the signal line extends from the mold part by fixing to the soft member and / or the pressure transmission member except for the vicinity of the mold part. This can be further prevented. In particular, as in the biological information detector according to claim 3, by arranging the signal lines in a meandering manner in the vicinity of the mold part, stress applied to the part where the signal lines extend from the mold part is applied to the meandering part. Therefore, it is possible to effectively prevent the occurrence of defects at the connection portion.

  In the biological information detection body according to claim 4 configured as described above, the pressure transmission member employs a configuration in which the detection portion and the mold portion are covered without any gap, so that the connection portion between the detection portion and the mold portion is provided. The applied stress can be further reduced. In particular, it can be easily created by configuring as in the biological information detector according to claim 5.

  In the bed apparatus according to claim 6 and the seating apparatus according to claim 7 configured as described above, in order to acquire the biological information from the biological information detection body according to any one of claims 1 to 5 described above. By adopting as a sensor, it is possible to provide a bed device and a seating device with excellent durability that can acquire biological information stably and with high sensitivity.

  The biological information detector, bed device, and seating device of the present invention will be described in detail below based on the embodiments.

(Biological information detector)
The living body information detection body of the present embodiment is a device used inside or in contact with a soft member made of a soft material to which pressure from a living body is applied, and includes a detection unit, a signal line, a mold unit, and a pressure transmission member. And have. Examples of the soft member include a sitting device such as a bed provided with a mattress as a soft member, a backrest as a soft member, and a chair provided with a seat. It is also possible to have a plurality of detection units. By arranging a plurality of detection units dispersed in the spreading direction of the mattress, it is possible to detect pressure fluctuations (body movements) at any part. In that case, it is desirable to adopt a form in which the signal line extends from each of the detection units, and each detection unit can be independently displaced by a pressure change from the outside. The biological information that can be detected as a change in pressure includes the presence or absence of a living body, body movements such as turning over, heartbeat, and breathing.

  The biological information detector of this embodiment has a detection part, a signal wire, and a pressure transmission member. The detection unit has a thin film shape and is a means for detecting the transmitted pressure fluctuation. By using a thin film, it is excellent in flexibility and can reduce or eliminate a sense of discomfort for the user. Although the magnitude | size in the expansion direction of a detection part is not specifically limited, The appropriate magnitude | size which can be determined with the object to which the biological information detection body of this embodiment is applied is employ | adopted. Specifically, if the size of the detection unit in the spreading direction is increased, the pressure fluctuation can be detected satisfactorily, and if it is decreased, local stress concentration can be effectively prevented. For example, when applied to a bed apparatus or chair, it is assumed that a large pressure is applied to the kneecap, elbow, heel, etc., so that a local deformation does not occur even when pressure is applied thereby ( For example, the size can be within a circle having a size of about 60 mm. As the detection unit, it is possible to employ a material that detects strain accompanying pressure fluctuation. Specifically, it is desirable to employ a piezoelectric element such as a piezoelectric polymer or piezoelectric ceramic. In particular, since the piezoelectric polymer is excellent in stretchability, it has a wide frequency characteristic, and is excellent in flexibility, impact resistance, high voltage resistance, water resistance, and chemical stability. An example of the piezoelectric polymer is polyvinylidene fluoride (PVDF).

  The signal line is means for transmitting the pressure fluctuation detected by the detection unit as a pressure fluctuation signal. Examples of the transmission destination include means for processing the biological information detected by the biological information detector. The pressure fluctuation signal can be transmitted electrically or transmitted as light. Processing means for performing signal processing in the vicinity of the detection unit before transmission through the signal line can be provided. Examples of the processing means include means for electrically amplifying or modulating the pressure fluctuation detected by the detection unit in order to enable efficient transmission. The signal line can be accompanied by an energy supply line for supplying energy (such as electric power) required for driving the processing means and the detection unit. The signal line itself can be shared as an energy supply line. The relationship between the signal line and the pressure transmission member will be described in detail in the description of the pressure transmission member.

  The mold part is attached to the connection part between the detection part and the signal line. In the case of having the processing means described above, the connection portion includes both a connection portion between the processing means and the detection unit and a connection portion between the processing means and the signal line. The mold part is formed of a hard material. The hard material is not particularly limited as long as it is more difficult to bend than the connection portion, but it is desirable that the hard material be hard to bend in the environment of the apparatus to which the present biological information detector is applied. The mold part can be formed from a resin. The resin can be filled with a filler such as silica or alumina. The shape of a mold part is not specifically limited, A rectangular parallelepiped etc. can be illustrated.

  The pressure transmission member is a member that effectively transmits the pressure fluctuation transmitted from the soft material on which the biological information detector is disposed and applied to the detection unit and prevents excessive stress from being applied to the detection unit. . The pressure transmission member has a shape that is in close contact with the detection unit. One pressure transmission member may be in close contact with one detection unit, or may be in close contact with a plurality of detection units. Specifically, the detection unit is in close contact with a portion that extends from the mold portion and is exposed (in other words, in appearance, in the vicinity of the portion where the mold portion of the detection unit is attached). The stress applied from the outside concentrates on the part where the detection part is exposed from the mold part and is applied to the boundary part, and the boundary part is most easily damaged as it is. In view of this, the pressure transmission member having a surface shape that can be brought into close contact with the surface shape of the detection unit holds the vicinity including the boundary portion, thereby suppressing the concentration of stress on the boundary portion. The overall shape of the pressure transmission member is not particularly limited, but a form in which a concave portion having a form in close contact with the mold part is formed in the part corresponding to the mold part can be exemplified. Due to the formed recess, the pressure transmission member can be brought into close contact with the entire detection portion and mold portion. In particular, it is possible to exemplify a mode in which the detection part is sandwiched between two flat members, and it is desirable to sandwich the mold part together. In that case, the pressure transmission member and the detection unit are not fixed without using an adhesive or the like at a site corresponding to the detection unit. It can also be fixed with an adhesive or the like between the pressure transmission member and the mold part. It is desirable that the signal line extending from the mold part is not fixed in the vicinity of the mold part. It is desirable to suppress the transmission of stress from the outside by meandering the unfixed signal lines in the vicinity of the mold part.

  The pressure transmission member is made of an elastic material. Although it does not specifically limit as an elastic material, An uncomfortable feeling can be eliminated by forming from the material which has an elasticity comparable as the soft member which the object applied has. Although the pressure transmission member is in close contact with the detection unit, the pressure transmission member is not fixed to the surface of the detection unit, and is disposed so as to be relatively movable with respect to the detection unit surface in the spreading direction of the detection unit. For example, the form which clamps a thin film-shaped detection part from the thickness direction is mentioned. By sandwiching from the thickness direction, the detection unit is stably held. However, since the detection unit is simply sandwiched, it can slide in the spreading direction of the detection unit, so that both can move relative to each other. Since the relative movement is possible, even if a deviation occurs between the movements of the two, the deviation is not transmitted to the detection unit, and an excessive stress is not applied to the detection unit. Examples of the elastic material constituting the pressure transmission member include polymer materials such as rubber and soft resin, and particularly porous materials such as foams.

(Bed device and seating device)
The bed apparatus and the seating apparatus of the present embodiment are apparatuses in which the biological information detection body of the present embodiment described above is provided and the biological information can be detected by the biological information detection body. Examples of the seating device include a chair, an automobile seat device, and a valve seat device for a Western-style toilet. It is desirable that the living body information detection body is disposed as close to the living body as possible as long as the uncomfortable feeling to the living body can be tolerated. Since the living body information detection body of the present embodiment described above can be adjusted to a size that does not cause the living body to feel uncomfortable, it can also be disposed close to the living body.

The method for disposing the biological information detector on the soft member is not particularly limited. For example, it can be fixed to a soft member with an adhesive, a thread, a pin or the like, or can be fixed with a hook-and-loop fastener or a double-sided tape.
-A bed apparatus has the mattress for a biological body to lie down, and the biological information detection body of this embodiment mentioned above. At least a part of the mattress is made of a soft member, and a biological information detector is disposed inside or on the surface of the soft member. By disposing a plurality of detection units in the spreading direction of the mattress and analyzing the detection results of the respective detection units, the state of the living body on the mattress can be detected in more detail. For example, it can be detected that the living body is approaching the end of the mattress and is about to fall.
The seating device includes a seating section main body for seating a living body and the above-described living body information detection body of the present embodiment. At least a part of the seating section main body is made of a soft member, and a living body information detector is disposed inside or on the surface of the soft member. By disposing a plurality of detection units in the spreading direction of the seating unit main body and analyzing the detection results of each detection unit, it is possible to detect the state of the living body on the seating unit main body in more detail.

(Embodiment 1: bed device)
(Constitution)
Hereinafter, the biological information detector of the present embodiment will be specifically described with reference to the drawings. The biological information detector of this embodiment is disposed in the mattress of the bed apparatus. As shown in FIGS. 1 and 2, the biological information detector 1 of this embodiment includes a detection unit 10, a signal line 20, a mold unit 30, and a pressure transmission member 40. The detection unit 10 has a structure in which a PVDF thin film is sandwiched between metal thin films that act as shields. The signal line 20 is derived from the detection unit 10 and transmits the pressure fluctuation detected by the detection unit 10 as a pressure fluctuation signal. The mold part 30 is attached so as to cover the connection part between the detection part 10 and the signal line 20, and its outer shape is a rectangular parallelepiped. The mold part 30 is formed of a hard resin. The length in the thickness direction of the detection unit 10 of the mold unit 30 is larger than each of the detection unit 10 and the signal line 20. The pressure transmission member 40 is made of urethane foam. The magnitude | size which the detection part 10 exposes from the mold part 30 is 40 mm in the direction extended from the mold part 30, and a width | variety is 10 mm. The part where the signal line 20 extends from the mold part 30 may be covered with an elastic tube (not shown). The elastic tube is less deformed by bending stress than the signal line 20, and the stress concentration on the part where the signal line 20 extends from the mold part 30 can be alleviated.

  The pressure transmission member 40 has two flat members, an upper pressure transmission member 41 and a lower pressure transmission member 42. As shown in FIG. 2, the upper pressure transmission member 41 and the lower pressure transmission member 42 have openings 411 and 421 penetrating the front and rear surfaces near the center, respectively. The openings 411 and 421 have such a size that the mold part 30 can be fitted without a gap. The detection unit 10 is held between the upper pressure transmission member 41 and the lower pressure transmission member 42 in a state in which the mold unit 30 is fitted and held by the openings 411 and 421. The upper pressure transmission member 41 and the lower pressure transmission member 42 are not fixed and are relatively movable with respect to the detection unit 10. A portion of the signal line 20 located between the pressure transmission members 40 (a portion near the mold portion 30) is a meandering portion 20a that is meandered.

  The biological information detectors 1 configured as described above are arranged 2 × 3 (six in total), and are sandwiched by urethane foam cushions 91 and 92 from both sides of each pressure transmission member 40. The cushions 91 and 92 are fixed with an adhesive. The signal line 20 held between the cushions 91 and 92 is also fixed to the cushions 91 and 92. The outer side of the cushions 91 and 92 is wrapped with sheet members 81 and 82 made of cloth or the like, and the peripheral part is thermally fused to form the biological information detection unit S (FIG. 3). Each signal line 20 is collectively transmitted to the signal processing unit 50, and pressure fluctuation is calculated. The calculated pressure fluctuation is related to the biological information by the biological information calculation unit 60. The association with the biological information is performed based on the fluctuation range, period, frequency, etc. of the pressure fluctuation. The holding member 70 is fixed to the sheet member 82. The holding member 70 is a hook-and-loop fastener.

  This biological information detection unit S is disposed in the bed apparatus B (FIG. 5). The bed apparatus B has a mattress main body portion 94 (soft member) formed with a concave portion large enough to accommodate a user H who is supposed to lie above the center portion, and a mattress surface that can be fitted into the concave portion without a gap. A holding member 95 formed of a hook-and-loop fastener corresponding to the holding member 70 and extending in the longitudinal direction of the mattress main body 94; and a holding member 95 fixed to the holding member 95. And a biological information detection unit S arranged. The biological information detection unit S is arranged with its longitudinal direction facing the width direction of the bed apparatus B. The biological information detection unit S is arranged in the bed device B where the user's heart, lungs, and shoulders are located.

(Function and effect)
Since it has the above structure, the bed apparatus of this embodiment exhibits the following effects. That is, since it is disposed at a position close to the user's heart or the like, the biological information emitted by the user can be detected with high sensitivity. In particular, since the pressure transmission member 40 is in close contact with the detection unit 10, the pressure fluctuation transmitted from the outside is effectively transmitted to the detection unit 10. The pressure fluctuation transmitted to the detection unit 10 is converted into an electrical signal and transmitted to the signal processing unit 50 through the signal line 20 to calculate the pressure fluctuation. Since the pressure fluctuation from the outside is effectively transmitted to the detection unit 10, the pressure fluctuation signal becomes relatively large and the influence of noise or the like is reduced. The biological information calculation unit 60 calculates and associates the biological information from the calculated pressure fluctuation.

  Next, the operation of other members when pressure is applied to each biological information detection body 1 in the biological information detection unit S will be described. Since the connection part between the detection part 10 and the signal wire | line 20 is coat | covered and protected by the mold part 30, the bending in a connection part becomes difficult to generate | occur | produce. Since the connection part has relatively low durability against bending compared to other parts, if the pressure fluctuation from the outside is transmitted to the connection part as it is, there is a high risk of damage to the connection part. Since it is protected from the generation by the mold part 30, damage to the connection part can be suppressed.

  Moreover, since the detection part 10 is clamped by the pressure transmission member 40, when a big pressure fluctuation is applied from the outside, deviation may arise between both. Since the detection unit 10 and the pressure transmission member 40 are not bonded to each other, even if a deviation occurs between the pressure transmission member 40 and the detection unit 10, the slip direction is left between them (the left-right direction in FIG. 1A). ), And local stress concentration on the detection unit 10 caused by deformation of the pressure transmission member 40 can be prevented. Specifically, as shown in FIG. 4, the upper pressure transmission member 41 and the lower pressure transmission member 42 are not bonded, and the detection unit 10, the mold unit 30, and the signal line 20 sandwiched therebetween are The pressure transmission member 40 can move freely to some extent. Since the cushions 91 and 92 are bonded to each other, the pressure transmission member 40 sandwiched between them is fixed, and the biological information detector 1 is displaced, and the part where the pressure fluctuation is detected moves to an unexpected part. Absent.

  In addition, as a large external force applied on the bed apparatus B, there are those caused by the kneecap and elbow, and if the external force is applied to a part of the detection unit 10 as it is, the detection unit 10 may be damaged. However, since the size of the detection unit 10 is 10 mm × 40 mm, these external forces are applied to the entire detection unit 10, so there is no risk of damage. In particular, even if an external force is locally applied from the pressure transmission member 40 to a part of the detection unit 10, the detection unit 10 is disposed in the pressure transmission member 40 so as to be relatively movable in the sliding direction. By sliding, local stress concentration can be prevented. Further, since the mold unit 30 is held by the openings 411 and 421 and the relative movement is limited, the relative movement of the detection unit 10 connected to the mold unit 30 is also limited. This can prevent the detection unit 10 from being deformed.

  As for the signal line 20, the portion sandwiched between the pressure transmission members 40 can be moved relative to the pressure transmission member 40, so there is no possibility that an external force is applied to the signal line 20 as the pressure transmission member 40 is deformed. . Moreover, since the site | part clamped by the pressure transmission member 40 is the meandering part 20a meandered, even if an external force is applied through the signal wire | line 20 by any chance, an external force is absorbed by the meandering part 20a.

(Embodiment 2: Seating device)
The seating device of this embodiment is a vehicle seat, and includes a seat cushion 96, a seat back 97, and a headrest 98, as shown in FIG. The biological information detector 1 is disposed in the seat cushion 96. Since the biological information detector 1 is the same as that described in the first embodiment, the description thereof is omitted. As shown in FIG. 6B, the biological information detector 1 is disposed between the seat skin 962 on the seating surface 961 of the seat cushion 96 and the pad 963 (soft member). Since the above-described biological information detector 1 is employed, local stress does not concentrate on a part of the detection unit 10 even when an external force is applied locally.
