  Next, the configuration of main functional blocks of the sphygmomanometer 100 will be described. FIG. 2 is a functional block diagram showing the configuration of the sphygmomanometer in FIG.

  Referring to FIG. 2, blood pressure measurement for supplying or discharging air through air tube 31 to air bag 151 contained in cuff 150 for blood pressure monitor is provided inside apparatus main body 110 of blood pressure monitor 100. An air system component 131 is provided. The blood pressure measurement air system component 131 includes a pressure sensor 132 that is a pressure detection means for detecting the pressure in the air bag 151, and a pump 134 and a valve 135 that are expansion and contraction means 133 for expanding and contracting the air bag 151. Have. In the apparatus main body 110, an oscillation circuit 125, a pump drive circuit 126, and a valve drive circuit 127 are provided in association with the blood pressure measurement air system component 131.

  The apparatus main body 110 includes a CPU (Central Processing Unit) 122 for centrally controlling and monitoring each unit, and a memory for storing various information such as a program for causing the CPU 122 to perform a predetermined operation and a measured blood pressure value. Power is supplied to the unit 123, the display unit 114 for displaying various information including blood pressure measurement results, the operation unit 115 operated to input various instructions for measurement, the CPU 122, and each functional block Power supply unit 124 is provided. The CPU 122 also functions as blood pressure value calculation means for calculating blood pressure values.

  The pressure sensor 132 detects the pressure in the air bladder 151 (hereinafter referred to as “cuff pressure”), and outputs a signal corresponding to the detected pressure to the oscillation circuit 125. The pump 134 supplies air to the air bag 151 through the air pipe 31. The valve 135 opens and closes when maintaining the pressure in the air bag 151 or exhausting the air in the air bag 151. The oscillation circuit 125 outputs a signal having an oscillation frequency corresponding to the output value of the pressure sensor 132 to the CPU 122. The pump drive circuit 126 controls the drive of the pump 134 based on a control signal given from the CPU 122. The valve drive circuit 127 performs opening / closing control of the valve 135 based on a control signal given from the CPU 122.

  Next, the flow of blood pressure measurement processing in the sphygmomanometer 100 will be described. FIG. 3 is a flowchart showing the flow of blood pressure measurement processing of the sphygmomanometer in FIG. A program according to this flowchart is stored in advance in the memory unit 123 shown in FIG. 2, and the CPU 122 reads out this program from the memory unit 123 and executes it, thereby executing blood pressure measurement processing.

  Referring to FIGS. 2 and 3, when the subject operates the operation button of operation unit 115 of sphygmomanometer 100 to turn on the power, sphygmomanometer 100 is initialized (step S1). Next, when measurement is possible, the CPU 122 starts driving the pump 134 and gradually increases the cuff pressure of the air bladder 151 (step S2). In the process of gradually increasing the cuff pressure, when the cuff pressure reaches a predetermined level necessary for blood pressure measurement, the CPU 122 stops the pump 134, and then gradually opens the closed valve 135 to open the air bag 151. The air is gradually exhausted and the cuff pressure is gradually reduced. The cuff pressure is detected during the slow cuff pressure reducing process (step S3).

  Next, the CPU 122 calculates a systolic blood pressure value (maximum blood pressure value) and a diastolic blood pressure value (minimum blood pressure value) by a known procedure (step S4). Specifically, in the process of gradually reducing the cuff pressure, the CPU 122 extracts pulse wave information based on the oscillation frequency obtained from the oscillation circuit 125. Then, a blood pressure value is calculated from the extracted pulse wave information. When the blood pressure value is calculated in step S4, the calculated blood pressure value is displayed on the display unit 114 (step S5).

  The measurement method described above is based on a so-called decompression measurement method that calculates a blood pressure value by detecting a pulse wave when the air bag is depressurized. It is naturally possible to adopt a so-called pressurization measurement method for calculating the blood pressure value.
