A second flow path 7b continuous with the sensing cuff 73 and a third flow path 7c connecting the first flow path 7a to the atmosphere are provided. Also, the first flow path 7a includes a first pressure sensor 17A. A first on-off valve 16A is provided between the first flow passage 7a and the second flow passage 7b. The second flow path 7b includes a second pressure sensor 17B. A second on-off valve 16B is provided between the first flow path 7a and the third flow path 7c.

In such a fluid circuit 7, only the first flow path 7a is connected to the pump 14 by the first on-off valve 16A and the second on-off valve 16B being closed, and the pump 14 and the pressure cuff 71 are fluidly connected. . In the fluid circuit 7, when the first on-off valve 16A is opened and the second on-off valve 16B is closed, the first flow path 7a and the second flow path 7b are connected, and the pump 14 and the pressure cuff 71, and the pump 14 and the sensing cuff 73 are fluidly connected.

Next, an example of measurement of a blood pressure value using the blood pressure measurement device 1 will be described with reference to FIGS. 19 to 24. 19 and 20 are cross-sectional views schematically showing the configuration of the pressure cuff 71 of the cuff structure 6 when inflated. FIG. 21 is a flow chart showing an example of blood pressure measurement using the blood pressure measurement device 1, and shows both the operation of the user and the operation of the control unit 55. 22 to 24 show an example where the user wears the blood pressure measurement device 1 on the wrist 100. FIG.

First, the user wears the blood pressure measurement device 1 on the wrist 100 (step ST1). As a specific example, for example, the user inserts one of the wrists 100 into the curler 5 as shown in FIG.

At this time, in the blood pressure measurement device 1, since the device body 3 and the sensing cuff 73 are disposed at the positions opposite to the curler 5, the sensing cuff 73 is disposed in the area where the artery 110 on the palm side of the wrist 100 exists. Thus, the device body 3 is disposed on the back side of the hand of the wrist 100. Next, as shown in FIG. 23, the second belt 62 is passed through the frame 61 d of the tail lock 61 c of the first belt 61 by the hand opposite to the hand where the user placed the blood pressure measurement device 1. Next, the user pulls the second belt 62, brings the member on the inner peripheral surface side of the curler 5, that is, the cuff structure 6 into close contact with the wrist 100, and inserts the rod 61e attached to the small hole 62a. Thereby, as shown in FIG. 24, the first belt 61 and the second belt 62 are connected, and the blood pressure measurement device 1 is attached to the wrist 100.

Next, the user operates the operation unit 13 to input a command corresponding to the start of measurement of the blood pressure value. The operation unit 13 which has performed the input operation of the command outputs an electric signal corresponding to the start of measurement to the control unit 55 (step ST2). When the control unit 55 receives the electric signal, for example, the control unit 55 opens the first on-off valve 16A and closes the second on-off valve 16B to drive the pump 14 to pass through the first flow path 7a and the second flow path 7b. Then, compressed air is supplied to the pressure cuff 71 and the sensing cuff 73 (step ST3). As a result, the pressure cuff 71 and the sensing cuff 73 start to expand.

The first pressure sensor 17A and the second pressure sensor 17B respectively detect the pressure of the pressing cuff 71 and the sensing cuff 73, and output an electrical signal corresponding to the pressure to the control unit 55 (step ST4). The control unit 55 determines whether the pressure in the internal space of the pressure cuff 71 and the sensing cuff 73 has reached a predetermined pressure for blood pressure measurement, based on the received electrical signal (step ST5). For example, when the internal pressure of the pressure cuff 71 does not reach a predetermined pressure and the internal pressure of the sensing cuff 73 reaches a predetermined pressure, the control unit 55 closes the first on-off valve 16A, and Compressed air is supplied through the flow path 7a.

When both the internal pressure of the pressure cuff 71 and the internal pressure of the sensing cuff 73 reach the predetermined pressure, the control unit 55 stops the driving of the pump 14 (YES in step ST5). At this time, as shown in FIG. 19, the pressing cuff 71 is fully inflated, and the inflated pressing cuff 71 presses the wrist 100 and the back plate 72.

Furthermore, the sensing cuff 73 is supplied with a predetermined amount of air so that the internal pressure is the pressure required to measure the blood pressure, is inflated, and is attached to the wrist 100 by the back plate 72 pressed by the pressing cuff 71. It is pushed towards. Therefore, the sensing cuff 73 presses the artery 110 in the wrist 100 and occludes the artery 110 as shown in FIG.

In addition, the control unit 55 controls the second on-off valve 16B and repeats opening and closing of the second on-off valve 16B or adjusts the degree of opening of the second on-off valve 16B to thereby Pressurize the pressure. Based on the electric signal output from the second pressure sensor 17B in the process of pressurization, the control unit 55 obtains measurement results such as blood pressure values such as systolic and diastolic blood pressure and heart rate.

Although the timing of opening and closing the first on-off valve 16A and the second on-off valve 16B at the time of blood pressure measurement can be set appropriately, the example has been described where the control unit 55 calculates blood pressure in the pressurization process of the pressure cuff 71 The blood pressure may be calculated in the depressurization process of the pressure cuff 71, or may be calculated in both the pressurization process and the depressurization process of the pressure cuff 71. Next, the control unit 55 outputs an image signal corresponding to the obtained measurement result to the display unit 12.

When the display unit 12 receives an image signal, the display unit 12 displays the measurement result on the screen. The user visually confirms the display unit 12 to confirm the measurement result. After the measurement is completed, the user removes the rod 61e from the small hole 62a, removes the second belt 62 from the frame 61d, and removes the wrist 100 from the curler 5, whereby the blood pressure measurement device 1 is removed from the wrist 100. Remove.

The blood pressure measurement device 1 according to the embodiment configured as described above can easily manufacture the cuff structure 6 with a small number of parts. That is, by configuring the plurality of cuffs 71 and 73 each formed in a bag shape by using the common sheet members 86 and 87, the number of parts and molds is increased as compared to the case of configuring with different sheet members. Can be reduced, and the manufacturing cost can be kept low.

In addition, the sheet members 86 and 87 integrally including the plurality of cuff parts 86a, 86b, 87a, and 87b are bent at the boundary portion, so that the plurality of cuffs 71 and 73 are overlapped by bending at predetermined positions. The work of aligning and the position can be easily adjusted.

Furthermore, by integrally forming the tubes 82 and 92 connected to the plurality of cuffs 71 and 73 by the common sheet members 86 and 87, the number of parts can be reduced compared to the case where they are formed by different sheet members. Can. Moreover, since the alignment process and the connection process of the tubes 82 and 92 and the cuffs 71 and 73 become unnecessary, the manufacturing process can be simplified.

Furthermore, the tubes 82 and 92 can be easily configured by forming the slit- like cuts 86 k and 87 k between the tubes 82 and 92 and the portions that constitute the air bladders 81 and 91. Moreover, it is easy to arrange the tube 92 and the air bladder 91 on the opposite sides of the cuff structure 6 by passing through the gaps formed by the cuts 86k and 87k, and the connection work becomes easy. Further, by disposing the tubes 82 and 92 on the opposite side to the living body side, it is possible to prevent the blocking of the blood vessel by the pressing cuff 71 from being disturbed, and the measurement accuracy can be improved.
