  The pressurization pump 16 a, the exhaust valve 16 b, and the pressure sensor 16 c correspond to the air system component 16 in the sphygmomanometer 100. The pressurizing pump 16 a and the exhaust valve 16 b correspond to an inflating / contracting mechanism in the sphygmomanometer 100 for inflating and deflating the air bladder 34.

  The air bag 34 has an expansion / contraction space as a lumen therein as described above. The air bag 34 is connected to each of the pressurizing pump 16a, the exhaust valve 16b, and the pressure sensor 16c via an air pipe 80.

  The control unit 11 is composed of, for example, a CPU (Central Processing Unit). The control unit 11 controls the entire sphygmomanometer 100. The display unit 12 is configured by, for example, an LCD (Liquid Crystal Display). The display unit 12 displays measurement results and the like.

  The memory unit 13 includes a processing memory 13a and a data memory 13b. The memory unit 13 stores a program for causing the control unit 11 or the like to execute a processing procedure for blood pressure value measurement, or stores a measurement result or the like, using the processing memory 13a and the data memory 13b.

The operation unit 15 includes a power switch 15a, a measurement switch 15b, a stop switch 15c, and a record call switch 15d. The operation unit 15 receives an operation of each of the switches 15 a to 15 d by a subject or the like, and inputs a command from the outside to the control unit 11 or the power supply unit 14.

  The control unit 11 inputs control signals for driving the pressurization pump 16a and the exhaust valve 16b to the pressurization pump drive circuit 17a and the exhaust valve drive circuit 17b, respectively. The control unit 11 inputs a blood pressure value as a measurement result to the memory unit 13 or the display unit 12.

  The control unit 11 includes a blood pressure information acquisition unit (not shown) that acquires the blood pressure value of the subject based on the pressure value detected by the pressure sensor 16c.

  The pressure sensor 16c inputs an output signal corresponding to the pressure inside the air bladder 34 to the oscillation circuit 17c. The oscillation circuit 17c generates a signal having an oscillation frequency corresponding to the signal input from the pressure sensor 16c, and inputs the generated signal to the control unit 11.

(Processing flow of blood pressure monitor 100)
The processing flow of the sphygmomanometer 100 will be described with reference to FIGS. 4 and 5. A program following the processing flow of the sphygmomanometer 100 is stored in the memory unit 13 in advance. When the control unit 11 reads out and executes this program from the memory unit 13, the process of the sphygmomanometer 100 is executed.

  When measuring the blood pressure value, the subject wears the cuff 40 on the upper arm or the like in advance. In this state, the subject operates the operation unit 15 (power switch 15a) provided in the main body 10 to turn on the blood pressure monitor 100 (step ST1).

  Power as a power source is supplied from the power supply unit 14 to the control unit 11 to drive the control unit 11. The control unit 11 initializes the memory unit 13 (step ST2). Control unit 11 initializes pressure sensor 16c (step ST3).

  The control unit 11 waits for an instruction to start measurement by the subject. The subject operates the operation unit 15 (measurement switch 15b) as an instruction to start measurement (step ST4). The control unit 11 closes the exhaust valve 16b and drives the pressure pump 16a. Pressurization of the air bag 34 is started (step ST5).

  The cuff pressure of the air bag 34 increases. The cuff pressure of the air bag 34 reaches a predetermined cuff pressure or higher necessary for blood pressure measurement (step ST6). The control unit 11 stops the pressurizing pump 16a and opens the closed exhaust valve 16b. The air in the air bladder 34 is exhausted, and the decompression of the air bladder 34 is gradually started (step ST7).

  In sphygmomanometer 100 in the present embodiment, the blood pressure value is measured in the process of gradually reducing the cuff pressure. The sphygmomanometer 100 calculates blood pressure values such as systolic blood pressure values and diastolic blood pressure values by the control unit 11 (step ST8).

  The control unit 11 extracts pulse wave information based on the oscillation frequency obtained from the oscillation circuit 17c in the process of gradually reducing the cuff pressure of the air bladder 34. The control unit 11 determines a blood pressure value based on the extracted pulse wave information (step ST9).

  When the blood pressure value is determined, the control unit 11 opens the exhaust valve 16b to completely exhaust the air in the air bag 34 (step ST10). The control unit 11 displays the blood pressure value as the measurement result on the display unit 12 (step ST11). The control unit 11 stores the blood pressure value in the memory unit 13 and records it as data (step ST12).

  The subject operates the operation unit 15 (power switch 15a) provided on the main body to turn off the power of the sphygmomanometer 100. When the power is turned off, the operation of the sphygmomanometer 100 ends (step ST13).

  The measurement method described above is a so-called decompression measurement method that detects a pulse wave when the air bag 34 is decompressed. The measurement method of the sphygmomanometer 100 in the present embodiment is not limited to the decompression measurement method, and a so-called pressurization measurement method that detects a pulse wave when the air bag 34 is pressurized may be employed.
