Description

Nursing device and its system

The present invention provides a nursing device and a system thereof for sensing the movement state of a user on a hospital bed, and is particularly a nursing device and system suitable for judging the movement of the center of gravity or the abnormal condition of the weight sensing value.

In general, patients with mobility impairments, lying in hospital beds for a long time, need someone to help massage regularly, otherwise they are prone to bedsores. However, some nursing or medical staff are responsible for a large number of patients, and it is inevitable that there are omissions, or although there are few patients in charge of nursing, they are easy to be lazy and difficult to manage without the supervision of others. In either case, inadequate care and poor medical results are prone to occur. In the prior art, thermal imaging is used to display high temperature on the patient to determine whether there is a bed sore. However, the body temperature of a patient is different, and it is difficult to judge whether there is a bed sore by comparing it with a standard temperature threshold. In addition, thermal imaging is a non-contact thermal sensing technology, which is susceptible to intermediate barriers. For example, when the patient is covered with a quilt, it is difficult to judge the bed sore of the patient under the quilt by thermal imaging.

In addition, when a patient with mobility impairment or insanity slips from the bed to the ground, because it is already difficult to take care of his own life, he can only start treatment when he is on the ground waiting for the caregiver to pass by. Although there are regular inspections in the ward, it is still difficult to deal with it immediately. It is probably the prime time for first aid, and it is difficult to recover the patient if the time is missed.

The invention provides a nursing device for sensing the movement state of a user on a hospital bed. The nursing device includes: a plurality of force sensors, which are respectively arranged in a plurality of supporting parts between the bed board and the base of the hospital bed; and an analysis unit, which determines the user's center of gravity based on the sensing value of the force sensor Position and weight sensing value, where when the user's center of gravity position appears to move quickly, or the weight sensing value is abnormal, the analysis unit sends out a reminder signal.

In one embodiment, when the user's center of gravity position moves faster than a dangerous speed, or the user's center of gravity position moves rapidly from the edge of the bed to the outside of the bed, the alert signal issued by the analysis unit includes that the user may be suddenly Danger of moving, or falling.

In one embodiment, when the movement history record of the user's center of gravity position shows that the user has not turned over within a predetermined period of time, the reminder signal sent by the analysis unit includes that the user needs to turn over; or when the nursing device is within a predetermined period of time If the first care mode is not entered, the reminder signal sent by the analysis unit includes that the user needs to enter the care mode. In one embodiment, when the nursing device is in this nursing mode, the analysis unit records the user's center of gravity position and weight sensing value, and does not issue a reminder signal based on the center of gravity position and weight sensing value.

In one embodiment, when the user's weight sensing value drops instantly and falls below a predetermined weight ratio, the alert signal sent by the analysis unit includes the risk of the user falling.

In one embodiment, the nursing device further includes an air cushion, which includes a pressure sensor or a flow sensor for sensing the user’s heartbeat and breathing. When the measured value is abnormal, the analysis unit sends out a reminder signal.

In one embodiment, the force sensor includes a pressure sensor or a weight sensor.

In one embodiment, the number of force sensors is three, four, or more than four. In one embodiment, the analysis unit performs the calibration of the sensed value according to the sensed value of the force sensor.

In one embodiment, the base of the hospital bed includes a plurality of wheels or a plurality of bed legs.

The foregoing and other technical content, features, and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

According to Figures 1 and 2, the nursing device 10 provided by the present invention includes a plurality of force sensors 100 and an analysis unit 200 connected to the force sensor 100 with signals. The signal connection method can be achieved by Wired or wireless. The nursing device 10 is used for sensing the movement state of a user P on the hospital bed B. The nursing device 10 includes: a plurality of force sensors 100 respectively disposed in a plurality of supporting parts B300 between the bed board B100 and the base B200 of the hospital bed B; and an analysis unit 200, according to the force sensor 100 Measured value to determine the position of user P's center of gravity on bed B And the weight sensing value. When the center of gravity of the user P moves or the weight sensing value is abnormal, the analysis unit 200 sends out a reminder signal Alarm. The position of the center of gravity GC and the weight sensing value of the user P on the hospital bed B will affect the sensing value of each force sensor 100. For example, from the top view direction (perpendicular to the bed direction of the hospital bed B), the sensing value of the force sensor 100 near the user P (that is, the force sensor 100 near the center of gravity position GC of the user P) When the user P is far away from the force sensor 100 (that is, the user P’s center of gravity position GC is far away from the force sensor 100 Value), its sensing value will be smaller. The weight sensing value of the user P, when the support between the bed board and the base is provided with force sensors 100, can be obtained by adding up the weight sensing values of each force sensor 100 corresponding to the user P Weight sensing value. Alternatively, when the force sensor 100 is provided in a part of the support between the bed board and the base, the weight sensing value of the user P can be obtained by mechanical calculation.

In the foregoing embodiment, the force sensor 100 is disposed in the supporting part B300, and its setting method may include: sensing the force of each supporting part B300 according to the force deformation of each supporting part B300; or, the force receiving The sensor 100 is arranged inside the support part B300, and directly receives the force received by the support part B300 for sensing; or, a pulsation source is installed on the bed B, and according to the pulsation movement of each support part B300 corresponding to the pulsation source, and Different vibration responses of each supporting part B300 are generated to determine the position of the center of gravity GC of the user P on the hospital bed B and the weight sensing value. This calculation method is a known technique in mechanics, and its detailed processing method will not be repeated here. In practical operation, the force sensor 100 may include a pressure sensor, a weight sensor, or other types of sensors.

In addition, the sensing value generated by each force sensor 100 is not only affected by the user P, but also affected by the hospital bed B. The influence of bed B, such as the weight of the bed plank and bed frame, are all fixed values. Therefore, to determine the impact of user P, you only need to exclude the impact of bed B. A sensed value corresponding to the influence of the user P is generated.

In one embodiment, when the position of the center of gravity GC of the user P moves too fast, this is an unreasonable sensing value for a patient who needs long-term care, and represents an abnormal situation. Especially when the moving speed of the GC position of the center of gravity is higher than a dangerous speed (for example, the mattress slips off), or the position of the user's center of gravity moves rapidly from the edge of the bed to the outside of the bed (for example, the user P slides from the bed B to the ground, Figure 2A) . At this time, the analysis unit 200 can send out a warning signal Alarm according to these situations, and the warning signal Alarm message may include that the user P may suddenly move or fall.

In the foregoing embodiment, the judgment of dangerous speed and rapid movement can be preset with a preset value; or, based on a multiple of the historical movement speed of the center of gravity position speed of the user P, set this preset value; or Set this preset value according to a multiple of the historical moving speed average of the moving speed of the user P2 in the previous predetermined time (for example, several days, weeks, or months). In this way, it is possible to flexibly determine whether the user P is likely to move suddenly or fall down according to the habits of each user P.

In addition, sometimes the user may be improperly moved due to other reasons. According to the present invention, the system can also be actively judged for emergency treatment and reduce the workload of nursing or medical personnel.

In one embodiment, regarding bed sore or hygiene care, when the historical record of the movement of the center of gravity of the user P shows that the user P has not turned over within a predetermined period of time (for example, two hours or other time periods), the analysis unit The reminder signal sent by 200 includes reminding the caregiver that user P needs to turn over. However, when performing nursing, the user P may be mistakenly judged as having a sudden movement, or when the movement performed by the nursing staff is slightly larger, it may be mistakenly judged as a risk of falling. At this time, the nursing device 10 can be cut Switching to a care mode, the analysis unit 200 records the user P's center of gravity GC position and weight sensing value related data, and does not issue a reminder signal based on the center of gravity GC position and weight sensing value. At this time, the purpose of the analysis unit 200 to record related data includes recording whether the caregiver actually performed the caregiving action, and can compare the most recent related data to determine whether there is a possibility of mistakes in the caregiving action.

In one embodiment, when the nursing device 10 does not enter a nursing mode within a predetermined time period, the analysis unit 200 may issue a reminder signal to remind nursing or medical personnel that the user P needs to enter the nursing mode.

In one embodiment, regarding the emergency treatment to prevent the user P from falling out of the bed, or the user P from falling out of the bed, when the weight sensing value of the user P drops instantaneously and falls below a predetermined weight ratio, the analysis unit 200 issues a reminder Signals, including user P may be in danger of falling. When the user P rolls out of the hospital bed B, the weight sensing value of the user P will instantly approach zero. Or, when the user P rolls, the head is on the hospital bed B, the lower part of the body is on the ground, or the head is under the hospital bed B, and the lower part of the body is on the hospital bed B. At this time, the user P is still in a dangerous state . The processing method of the system is that when the weight sensing value of the user P is lower than a predetermined weight ratio, the alert signal sent by the analysis unit 200 includes the risk of the user P falling.

3, which shows an embodiment, the nursing device further includes an air cushion 300, which includes a pressure sensor 310 (or a flow sensor) for sensing the heartbeat and breathing of the user P, where When the user P's heartbeat sensing value or breathing sensing value is abnormal, the analysis unit 200 issues a reminder signal.

In the present invention, the generated sensing signals of various sensors can be time-domain or frequency-domain signals as required.

In an embodiment, the number of force sensors 100 may be three, four, or more than four. Referring to FIG. 1, when the number of force sensors 100 is three, the force sensors 100 are not in a common line in the top plan direction. When the force sensor 100 is collinear with the center of gravity GC, the position of the center of gravity GC cannot be determined. When the number of force sensors 100 is four or more, the analysis unit 200 can be based on the combination of different force sensors 100 (for example, grouping any three of the force sensors 100, and then The positions of the center of gravity GC generated by the three force sensors 100) in other groups are arranged and combined, and the sensing values are compared and verified. When one of the force sensors 100 fails, this method can be used to find the failed force sensor 100 to reduce the error of the sensing value.

Referring to Fig. 4, the bed B to which the nursing device of the present invention is applicable is not limited to a base B200 including a plurality of wheels, and may also include a base B200 with a plurality of bed legs. In addition, the nursing device of the present invention can be applied to various types of bases, and is not limited to the examples shown in the drawings.

The related technology of the nursing device provided by the present invention is not limited to the foregoing embodiment. For example, the nursing device of the present invention can be combined with a billboard arranged near the hospital bed. When a reminder signal is issued, the billboard displays relevant information (such as turning over reminder, etc.) to facilitate further processing by nursing or medical personnel.

In addition, the aforementioned reminder signals are not limited to wired or wireless signals, but can also be reminders such as network, color, optical, sound, text, etc. The nursing device can determine the required reminder signal method according to needs.

In one embodiment, the nursing device provided by the present invention may further include an identity recognition function. According to the identified identity, sensor data related to the identity or related medical records are input into the nursing device, nursing or Medical staff can directly inquire about the user's relevant information on the nursing device (or check the information on the aforementioned signboard), which can save a lot of time for consulting medical records. It is more convenient to make comprehensive judgments directly at the bedside, so as to achieve the effect of timely treatment at the first time.

A plurality of force sensors 100 are respectively arranged in a plurality of supporting positions between the bed board and the base of the hospital bed. The analysis unit 200 judges the user’s center of gravity position and weight sensing value based on the sensing value generated by the force sensor 100, wherein when the user’s center of gravity position moves quickly or the weight sensing value is abnormal, The analysis unit 200 sends out an alarm signal Alarm. The warning unit 30 (for example, the aforementioned billboard, or a unit that generates warning messages such as network, color, optics, sound, text, etc.) is used to display the warning signal Alarm. The communication unit 40 is used for wireless communication with a remote device, and transmits the information generated by the analysis unit to the remote device, or transmits the user's nursing information stored in the remote device to the analysis unit. Its function may include using the transmitted information as historical data or auxiliary analysis.

Referring to Fig. 6, a nursing system 2 according to another embodiment is shown. Similar to the nursing system 1 in FIG. 5, the nursing system 2 in FIG. 6 also includes a warning unit 30 and a communication unit 40. However, the nursing device 20 of the nursing system 2 is slightly different from the nursing device 10 (the nursing system 1). The nursing device 20 further includes an air cushion 300 for sensing the user's heartbeat and breathing. For the detailed content of the nursing system 2, please refer to the description of the foregoing embodiment, and will not be described here.

However, the technology of the present invention may not be limited to the application of the bed board, such as the application of the seat cushion. For example, the nursing device of the present invention includes: a plurality of force sensors, which are respectively arranged in a plurality of supporting parts between the main body and the base of a cushion; and an analysis unit, which generates the force sensor The sensed value is used to determine the position of the user’s center of gravity and the weight sensed value. When the user's center of gravity moves rapidly, or the weight sensing value is abnormal, the analysis unit sends out a reminder signal.
