  The present invention relates to a biological information measuring device, a biological information measuring device bed, and a biological information measuring method for measuring biological information of a subject such as sleeping.

  In medical facilities and nursing care facilities, measure biological information (weight, respiration rate, heart rate, body movement, etc.) while a subject is sleeping in order to grasp the health status of the subject such as a sick person, infant, elderly person, etc. Has been done. In recent years, many biological information measuring devices used for this measurement have been developed (for example, refer to Patent Documents 1-3). As one of these devices, one having the following configuration is known.

  That is, in this apparatus, load cells are attached to the lower ends of the four leg portions of the bed as weight sensors, respectively. Then, the total load of the bed where the subject stays is measured by a load cell, and the biological information of the subject is measured based on the measured variation in the load (see, for example, Patent Document 1).

In the above-described apparatus, since the total load of the body weight of the subject and the weight of the bed is measured by the load cell, the absolute weight of the subject can be measured by subtracting the weight of the bed from the measured load. There are advantages.

Specifically, the bed surface component (2) includes an upper body receiving body (3) that receives the upper body of the subject, a buttocks receiving body (4) that receives the buttocks of the subject, and a leg receiving body that receives the legs of the subject. (5). The upper body receiving body (3), the buttocks receiving body (4), and the leg receiving body (5) are arranged at positions corresponding to the upper body, the buttocks and the leg parts of the subject, respectively.

  The bed (1) is a gatch bed, and therefore the upper body receiving body (3) of the bed surface component (2) can be raised at a predetermined angle with respect to the horizontal plane as shown in FIG. Yes.

  The upper body receiving body (3), the buttocks receiving body (4) and the leg receiving body (5) of the bed surface component (2) are all made of a plate material (specifically, a flat plate material), and aluminum (its alloy) The same shall apply hereinafter.) The upper body receptacle (3) is formed in a substantially quadrangular shape in plan view.

It may be plastic. Further, the upper body receiving body (3), the buttocks receiving body (4), and the leg receiving body (5) may be made of an extruded material or a rolled material.

  Further, the bed (1) has a support member (19) for supporting the upper body receiving body (3) as shown in FIG. The support member (19) is disposed below the upper body receptacle (3).

  In this 1st Embodiment, this bed (1) is arrange | positioned as a supporting member (19) on the lower side of the intermediate part of the left-right direction (namely, width direction) of an upper body receiving body (3), and an upper body receiving body (3) A central support frame (6) extending in the length direction of the left and right and a pair of left and right left-hand sides disposed below the left and right sides of the upper body receiving body (3) and extending in the length direction of the upper body receiving body (3) Side support frame (7L) and right side support frame (7R), and a pair of ends arranged in the longitudinal direction of upper body support (3) and extending in the left-right direction of upper body support (3) And supporting frames (8) and (8). The left side support frame (7L), the right side support frame (7R), and both end support frames (8) and (8) are assembled in a substantially rectangular shape in plan view. Each frame is made of metal such as aluminum.

  The center support frame (6) is fixed and attached to the upper surface of the middle part in the left-right direction of both end support frames (8) and (8) by welding or the like. (9) is a reinforcing frame. The reinforcing frame (9) is fixed to the lower surfaces of the left side support frame (7L) and the right side support frame (7R) by welding or the like.

  Of the both end support frames (8) and (8), the frame (8) and the reinforcement frame (9) disposed on the lumbar side of the subject are a pair of left and right movable arms (16) protruding from the shaft frame (15) ( It is fixed to 16) by welding or the like. When the shaft frame (15) is driven to rotate, the movable arm (16) rotates about the shaft frame (15), thereby causing the upper body support (3) to be raised at a predetermined angle with respect to the horizontal plane. It has been made. Reference numeral (17) denotes a bearing arm that rotatably supports the shaft frame (15).

  The upper body receiving body (3) is supported by being fixed to the central support frame (6) by welding or the like at its middle portion in the left-right direction. Furthermore, as shown in FIG. 2 (B), the left and right ends of the upper body support (3) are spaced apart from the left side support frame (7L) and the right side support frame (7R), that is, It is considered as a free end. Furthermore, both ends in the length direction of the upper body receiving body (3) are arranged apart from the both end support frames (8) and (8). Therefore, the upper body receiving body (3) is supported only by the central support frame (6). In other words, the left half (21) located on the left side and the right half (22) located on the right side of the support position of the upper body support (3) by the center support frame (6) are divided into the center support frame (6 ) Are supported in a cantilever shape. Therefore, the left half part (21) and the right half part (22) of the upper body receiver (3) are each a cantilever part (29) of the upper body receiver (3).

  In the present invention, the upper body receiving body (3) may be fixed to the central support frame (6) by a fastening member (eg, bolt-nut, rivet) or the like in addition to welding.

  Here, in this specification, for convenience of explanation, a region from the waist part to the shoulder part of the subject is referred to as “a chest peripheral part including the subject's chest”.

  In the part corresponding to the chest peripheral part including the subject's breast part of the left half part (21) of the upper body receiving body (3), both upper and lower surfaces of the part near the support position by the central support frame (6) of the part are opposed to each other. Two pairs of strain gauges (40a), (40a), (40b), and (40b) are directly attached and attached to the position where they are placed. These two pairs (that is, four) of strain gauges (40a), (40a), (40b), and (40b) are referred to as “left strain gauge group (40L)” for convenience of explanation. In addition, the strain gauges (40a) and (40b) are attached to a predetermined part with an adhesive, for example.

  In the left strain gauge group (40L), of the two pairs of strain gauges (40a) (40a) (40b) (40b), two strain gauges (40a) attached to the upper surface of the left half (21) In (40a), the upper body receiving body (3) receives the upper body of the subject and distorts (bends), whereby a tensile force acts. On the other hand, a compressive force acts on the two strain gauges (40b) (40b) attached to the lower surface of the left half (21). The two pairs of strain gauges (40a), (40a), (40b), and (40b) are electrically connected as shown in FIG. 3 to form a bridge circuit (41) (Wheatstone bridge circuit).

  Similarly, in the region corresponding to the chest peripheral portion including the subject's chest in the right half (22) of the upper body receiving body (3), the upper and lower surfaces of the vicinity of the support position by the central support frame (6) of the region Two pairs of strain gauges (40a), (40a), (40b), and (40b) are directly attached and attached at positions facing each other. The two pairs of strain gauges (40a), (40a), (40b), and (40b) are referred to as “right strain gauge group (40R)” for convenience of explanation.

  In the right strain gauge group (40R), the two pairs of strain gauges (40a), (40a), (40b), and (40b) are electrically connected as shown in FIG. 2 in the same manner as the left strain gauge group (40L). Thus, a bridge circuit (41) is formed.

  The strain gauges (40a) and (40b) are for detecting vibrations of the upper body receiving body (3) caused by biological activities such as breathing, heartbeat (beat), body movement (eg, turning over) of the subject. Further, in the first embodiment, the strain gauges (40a) and (40b) also detect the strain amount (deflection amount) of the upper body receiver (3) generated by the upper body receiver (3) receiving the subject. Has been made. On the other hand, the left half piece (21) and the right half piece (22) of the upper body receiving body (3) to which the strain gauges (40a) and (40b) are attached function as strain generating bodies.

  The output voltage as an output signal from the strain gauges (40a) (40b) is used for measurement of the biological information of the subject. In the first embodiment, since the two pairs of strain gauges (40a) (40a) (40b) (40b) are electrically connected to form a bridge circuit (41), the bridge circuit (41) The output voltage as an output signal from is used to measure the biological information of the subject.

  In the present invention, the types of strain gauges (40a) and (40b) are not limited, and for example, resistance strain gauges, foil strain gauges, and semiconductor strain gauges are used as the strain gauges (40a) and (40b). .

  Further, as shown in FIG. 1, the biological information measuring apparatus (A1) includes a calculation means (50), a display means (55), a communication means (56), and an alarm means (57).

  The computing means (50) is for computing the biological information of the subject based on the output signals (output voltage) from the strain gauges (40a) and (40b). In the first embodiment, since the two pairs of strain gauges (40a) (40a) (40b) (40b) are electrically connected to form a bridge circuit (41), the calculation means (50) As shown in FIG. 4, the biological information of the subject is calculated based on the output signal (output voltage) from the bridge circuit (41). In FIG. 1, (59) is a signal line for transmitting the output signal (output voltage) from the bridge circuit (41) to the computing means (50).

  The display means (55) is for displaying the biological information of the subject calculated by the calculation means (50).

  The communication means (56) is for transmitting the biological information of the subject calculated by the calculation means (50) to a remote place.

  The warning means (57) is for issuing a warning based on the biological information of the subject calculated by the calculation means (50).

  The display means (55) may be configured to display the biological information of the subject transmitted to the remote place by the communication means (56), and the alarm means (57) It goes without saying that an alarm may be issued based on the biological information of the subject transmitted to the remote place by 56).

  Thus, in the calculation means (50), as shown in FIG. 4, after the output signal (output voltage) from the bridge circuit (41) is amplified in the amplification section (51), the A / D conversion section (analog) / Digital conversion unit) (52), the digital signal is converted. Then, this digital signal is transmitted to a central processing unit (53) comprising a computer or the like. In the central processing unit (53), calculation is performed on biological information such as breathing information, heart rate information, and body motion information of the subject according to a predetermined program based on the digital signal. This calculation is performed by a known method, for example, frequency analysis by the FFT method.

  Further, in the central processing unit (53), a calculation is performed for the sleeping position as the subject's lying position on the bed surface component (2) of the bed (1). Briefly explaining this calculation method, for example, in this central processing unit (53), the output signal (output voltage) from the bridge circuit (41) assembled with the strain gauge of the left strain gauge group (40L), The output signal (output voltage) from the bridge circuit (41) assembled with the strain gauges of the right strain gauge group (40R) is compared using a predetermined calculation formula, and based on the comparison result, the bed (1) Calculation is performed on the sleeping position of the subject on the bed surface component (2).

  Further, in the central processing unit (53), calculation is performed on the subject's landing / leaving information.

  In the display means (55), the subject's biological information (breathing information, heartbeat information, body movement information, etc.) calculated by the computing means (50), sleeping position information, landing / leaving information, etc. are stored in a predetermined monitor TV or the like. Is displayed in real time on the display.

  In the communication means (56), the subject's biological information, sleeping position information, landing / leaving information, etc. calculated by the calculating means (50) are used for predetermined wired communication such as a telephone line network, the Internet, a wired LAN, and a wireless LAN. It is transmitted to a monitoring room such as a nursing center via a network or a wireless communication network.

  In the alarm means (57), when the subject's biological information, sleeping position information, landing / leaving information, etc. calculated by the calculating means (50) are out of the predetermined range, the alarm is issued by a nurse, subject, monitor, etc. Issued against.

  FIG. 6 is a diagram (graph) showing an actual measurement example of the output signal from the bridge circuit (41) when the biological information of the subject is actually measured by the biological information measuring device (A1) of the first embodiment. is there.

  In the figure, the output signal from the bridge circuit (41) is represented as a waveform. In this output waveform, a respiratory wave component resulting from the subject's breathing and a heartbeat component resulting from the subject's heartbeat (beat) are superimposed. A wave having a long wavelength and continuous wave is a respiratory wave component, and a pulse wave is a heart wave component. In this output waveform, the respiratory cycle is about 3-4 seconds and the heartbeat cycle is about 1 second.

  As shown in the figure, according to the biological information measuring apparatus (A1) of the first embodiment, the respiratory wave component and the heartbeat component can be clearly observed. Therefore, the respiratory information (respiration rate, etc.) and the heartbeat Information (such as heart rate) can be accurately measured.

  Next, processing executed by the central processing unit (53) of the computing means (50) will be described below with reference to FIGS.

  In the calculation means (50), a suitable sleeping position of the subject on the bed surface component (2) of the bed (1) is set in advance, and the respiratory rate, heart rate and body motion number of the subject are set. A preferable range of is set in advance.

  As described above, the output signals from the two bridge circuits (41) and (41) are amplified by the amplification unit (51) and then converted into digital signals by the A / D conversion unit (52). Then, this digital signal is transmitted to the central processing unit (53).

  In the central processing unit (53), in step (S1), the two transmitted signals are read. The read signal is stored as data in a database (DB) (see FIG. 4). Note that the read signal may be transmitted to a remote place by the communication means (56) and accumulated in the database (DB) as data. Then, the data group of the subject is patterned from the database (DB). For example, the data stored in the database (DB) is previously patterned into a data group when the subject is normal, a data group when the subject has caused a problem in the past, and the like. Note that the pattern of the data group when the subject has caused a problem in the past may be learned and registered and stored in the database (DB). And in a determination means (70), a test subject's condition is determined by comparing the measured data group of a test subject with the data group (it is normal, at the time of a problem) previously patterned. Moreover, you may accumulate | store the data of several other test subjects in this database (DB). By doing so, it can be compared with other people's patterns, and the determination means (70) can also determine problems that the subject has not experienced from other people's past patterns. Further, as shown in the figure, signals from the other plurality of biological information measuring device beds (1) in which the other plurality of subjects are sleeping (lie down) are transmitted to the LAN or the Internet by the communication means (56). Etc., and may be stored as data in a database (DB). By doing so, the patterned data stored in the database (DB) can be shared. Next, the process proceeds to step (S2).

  In step (S2), the read two signals are compared, and the sleeping position of the subject on the bed surface component (2) of the bed (1) is analyzed based on the comparison result. Next, the process proceeds to step (S3).

  In step (S3), it is determined whether or not the sleeping position of the subject is a predetermined position on the bed surface component (2). If it is determined that the sleeping position is not a predetermined position (for example, the sleeping position is an end on the bed surface component (2)), the process proceeds to step (S11) as “No” and an alarm is issued. . Based on this warning, it is possible to take a measure for preventing the subject from falling from the bed (1). On the other hand, when it is determined that the sleeping position is the predetermined position (for example, the sleeping position is the central portion on the bed surface component (2)), the process proceeds to the next step (S4) with “Yes”. .

  In step (S4), the frequency is analyzed by a known method such as the FFT method. Next, the process proceeds to step (S5).

  In step (S5), the respiration rate is detected from the analyzed frequency. Next, the process proceeds to step (S6).

  In step (S6), it is determined whether or not the respiration rate is within a predetermined range. If it is determined that the respiration rate is out of the predetermined range, “No” is determined, and the process proceeds to step (S11) to issue an alarm. On the other hand, when it is determined that the respiration rate is within the predetermined range, the process proceeds to the next step (S7) as “Yes”. In this step (S6), for example, information on a subject's life and death, sleep state, sleep apnea syndrome, and the like can be obtained.

  In step (S7), the heart rate is detected from the analyzed frequency. Next, the process proceeds to step (S8).

  In step (S8), it is determined whether or not the heart rate is within a predetermined range. If it is determined that the heart rate is out of the predetermined range, the process proceeds to step (S11) as “No” and an alarm is issued. On the other hand, if it is determined that the heart rate is within the predetermined range, the process proceeds to the next step (S9) as “Yes”. In this step (S8), for example, information on the state of the subject such as life and death, sleep state, and the like can be obtained.

  In step (S9), body movements such as a subject's rollover are detected from the analyzed frequency. Next, the process proceeds to step (S10).

  In step (S10), it is determined whether or not the number of body movements such as the number of rollovers is within a predetermined range. If it is determined that the number of body movements is out of the predetermined range (for example, there is almost no body movement for a predetermined fixed time), “No” is determined and the process proceeds to step (S11) to issue an alarm. Based on this warning, it is possible to take measures to prevent the occurrence of pressure ulcers. On the other hand, when it is determined that the number of body movements is within a predetermined range (for example, body movements are moderate), the process returns to step (S1) as “Yes”.

  In the present embodiment, the following processing may be performed. That is, the judging means (70) compares the data newly sent to the database (DB) with the data already stored in the database (DB). Then, based on the result, the process proceeds to step (S11) to issue an alarm. The results are transferred to a database (DB) and accumulated.

  Thus, in the biological information measuring apparatus (A1) of the first embodiment, the strain gauges (40a) and (40b) are attached to a part of the bed surface component (2) of the bed (1). Have the following advantages.

  Of the various biological activities of the subject, vibrations of the bed surface component (2) caused by respiration and heartbeat can be reliably detected by the strain gauges (40a) and (40b). Therefore, in addition to the subject's landing / leaving information and body movement information (eg, turning over information), biological information that is extremely difficult to measure with conventional biological information measuring devices, especially with slight load changes, particularly respiratory information And heart rate information can be measured with high accuracy.

  Furthermore, it is not necessary to perform a strict alignment operation when the bed (1) is installed, so that the installation operation of the bed (1) can be easily performed.

  Furthermore, even if a person walks around the bed (1), it is possible to prevent a decrease in detection accuracy due to vibration of the floor on which the bed (1) is installed.

  Furthermore, since there is almost no time difference in vibration transmission, the reliability of the measured value of biological information is improved.

  Furthermore, the biological information of the subject can be measured even when the upper body receiving body (3) of the bed surface component (2) is raised at a predetermined angle with respect to the horizontal plane.

  Of course, since it is not necessary to increase the rigidity of the bed (1), the weight of the bed (1) can be reduced.

  In the biological information measuring device (A1) of the first embodiment, the biological information of the subject is formed by electrically connecting four strain gauges (40a) (40a) (40b) (40b). Since the measurement is based on the output signal from the bridge circuit (41), minute vibrations of the bed surface component (2) can be reliably detected. Therefore, the respiration information and heart rate information of the subject can be measured with higher accuracy.

  Further, the strain gauges (40a) and (40b) are provided on the upper body receiving body (3) among the upper body receiving body (3), the buttocks receiving body (4), and the leg receiving body (5). Since it is affixed, vibrations caused by the subject's breathing and heartbeat can be detected more reliably. Therefore, the respiration information and heart rate information of the subject can be measured with higher accuracy.

  In addition, since the biological information measuring device (A1) includes a predetermined calculation device (50) and a predetermined display device (55), the biological information of the subject can be reliably calculated, and the biological information of the subject can be calculated. It can be displayed reliably.

  Moreover, since the biological information measuring device (A1) is provided with the predetermined communication means (56), the biological information of the subject can be measured at a remote place, so that the sleeping state of the subject can be monitored at a remote place. it can.

  In addition, since the biological information measuring device (A1) is provided with a predetermined warning means (57), a warning is given to nurses, caregivers, monitors, etc. when the condition of the subject is outside the assumed range. I can inform you.

  Further, in the bed (1) used for the biological information measuring device (A1), the left half (21) and the right half (22) of the upper body receiving body (3) are each cantilevered to the center support frame (6). Since it is supported in a beam shape, the left half (21) and the right half (22) vibrate sensitively. The strain gauges (40a) and (40b) are attached to the left half (21) and right half (22), respectively, so that vibration caused by the subject's breathing and heartbeat can be detected more reliably. Can do. Therefore, the respiration information and heart rate information of the subject can be measured with higher accuracy.

  Furthermore, strain gauges (40a) and (40b) are attached to the left half (21) and right half (22) of the upper body receptacle (3), respectively, so that the subject's sleeping position on the bed (1) Can be detected.

  In addition, according to this biological information measuring device (A1), not only can the biological information during sleeping of the subject lying on the bed (1) be measured, but the subject is also in an awakened state (ie, awake). Lies on the bed (1), so that the biological information of the awakened subject can be measured.

  Further, the life activity monitoring system of the first embodiment includes the bed (1), the calculation means (50), the display means (55), the communication means (56) and the alarm means (in the biological information measuring device (A1)). 57). Therefore, according to this monitoring system, it is possible to more reliably monitor the state of body movement, breathing and heartbeat of the subject, and also more reliably monitor the bed leaving / landing situation and the sleeping position situation. Can do.

  FIGS. 7A and 7B are views for explaining a biological information measuring apparatus (A2) according to the second embodiment of the present invention.

It has a support frame (7L) and a right side support frame (7R), and a pair of end support frames (8) (8). These frames are assembled in a substantially square shape in plan view. Furthermore, the bed (1) is disposed as a support member (19) below the middle part in the longitudinal direction of the upper body receiver (3) and extends in the left-right direction of the upper body receiver (3) ( 10). The central horizontal frame (10) is fixed to both end frames (8) and (8) by welding or the like. The bed (1) does not have a central support frame ((6), see FIG. 2).

  The upper body receiving body (3) is divided into a left half piece (23) and a right half piece (24) at an intermediate portion in the left-right direction. Both the left and right half pieces (23) and (24) are substantially quadrangular in a plan view and are formed to have substantially the same size. A gap (G) is formed between the left and right half pieces (23) and (24).

Further, the right half piece (24) is supported by the central lateral frame (10) at its middle portion in the longitudinal direction. Further, the right half piece (24) is supported by being fixed to the corresponding end support frame (8) by welding or the like at the end portion located on the head side of the subject among the both ends in the length direction. On the other hand, of the both ends in the length direction of the right half piece (24), the end portion located on the waist side of the subject is disposed apart from the corresponding end support frame (8). Therefore, the part (29) located on the lumbar side of the subject with respect to the support position by the central horizontal frame (10) of the right half piece (24) is separated into the right side support frame (7R) and the central horizontal frame (10). It is supported like a cantilever. This part (29) is the cantilever part of the right half piece (24). In addition, the cantilever part (29) of a right half piece (24) is a site | part corresponding to the chest peripheral part including a test subject's chest.

  In addition, the strain gauges (40a) (40a) (40b) are located at opposite positions on the upper and lower sides of the vicinity of the support position of the left side support frame (7L) of the left half piece (23) of the cantilever part (29). Two pairs of (40b) are directly attached. These two pairs of strain gauges (40a), (40a), (40b), and (40b) are referred to as “left strain gauge group (40L)”. The two pairs of strain gauges (40a), (40a), (40b), and (40b) are electrically connected as shown in FIG. 2 to form a bridge circuit (41). The cantilever part (29) of the left half piece (23) to which these strain gauges (40a) (40a) (40b) (40b) are attached functions as a strain generating body.
