  FIG. 1 is an overall external view showing a configuration of a biological information measuring device to which a pressurizing device according to an embodiment of the present invention is applied.

The biological information measuring device 100 shown in FIG. 1 is a pressurizing device that includes a cuff 10 and a device main body 20 that supplies and exhausts air to and from the cuff 10, based on data acquired using the cuff 10. This is a device having a function of measuring blood pressure by using The biological information measuring device 100 is a non-invasive blood pressure (NIBP: Non Invasive Blood Pressure) type biological information measuring device that measures blood pressure and the like using the cuff 10. Further, the biological information measuring device 100 measures the blood pressure by the oscillometric method. In the oscillometric method, the cuff pressure is increased / decreased by supplying / exhausting air to / from a cuff 10 wound around a main part of a patient to be measured, and a pulse wave is detected at that time. In the detected pulse wave, the cuff pressure when the amplitude increase is relatively significant (or when the amplitude exceeds a specific ratio to the maximum value, etc.) is determined as systolic blood pressure (systolic blood pressure). The cuff pressure at a relatively significant time (or when the amplitude falls below a specific ratio with respect to the maximum value) is determined as diastolic blood pressure (diastolic blood pressure). In addition, the main parts to be measured for blood pressure include the upper arm, the thigh, the ankle, and the like.

  FIG. 2 is a block diagram illustrating a configuration of a main part of the device main body 20 in the biological information measuring device 100 to which the pressurizing device according to the embodiment of the present invention is applied.

For example, the apparatus main body 20 includes a measuring unit 201 having an amplifier, a filter, an A / D (analog / digital) converter (none is shown), and a supply / exhaust unit 22. Further, the apparatus main body 20 includes an arithmetic control unit 202, a memory 203, and a communication unit 204. The measurement unit 201 obtains cuff pressure data by performing signal processing such as amplification, high-frequency noise removal, and A / D conversion on a detection signal from a main part of the patient, for example, the cuff 10 mounted on the upper arm. By performing the blood pressure determination process on the cuff pressure data thus obtained, the measurement unit 201 acquires the blood pressure data.

  The supply / exhaust unit 22 of the measurement unit 201 supplies / exhausts air to / from the band-shaped bag body 12 of the cuff 10. The air supply / exhaust section 22 includes a connecting tubular section 24 connected to the band-shaped bag body 12 of the cuff 10. The specific configuration and connection state of the connecting cylinder 24 will be described later. By connecting the air supply / exhaust section 22 to the band-shaped bag body 12 of the cuff 10, the apparatus main body 20 can supply / exhaust air to / from the band-shaped bag body 12 and measure the blood pressure, that is, can determine the blood pressure.

  The air supply / exhaust section 22 includes a pump as an air supply section, and an exhaust valve (neither is shown) of the air supply / exhaust section 22 that functions as an exhaust section. The measuring unit 201 further includes an arithmetic processing unit (not shown) that executes a program for controlling the pump and the exhaust valve and a program for the blood pressure determination process, and a storage device (not shown) that stores these programs. Have. The measurement unit 201 controls the pump and the exhaust valve in the supply / exhaust unit 22 to obtain cuff pressure data and performs a blood pressure determination process. For example, the apparatus main body 20 closes the exhaust valve and starts the pump to supply air to the cuff 10 (specifically, the band-shaped bag body 12) wound around a main part (upper arm in this case) of the patient. When the air is supplied, the cuff pressure of the band-shaped bag body 12 is increased and the band-shaped bag body 12 is inflated. After inflating the band-shaped bag body 12, the device main body 20 (measurement unit 201) performs control to set the opening degree of the exhaust valve to a value corresponding to a predetermined reduced pressure speed, and brings the exhaust valve into a half-open state, Decrease the cuff pressure slowly. While the cuff pressure is being reduced, the apparatus main body (measurement unit 201) 20 performs a blood pressure determination process. For example, while detecting the vibration of the cuff pressure during the depressurization of the cuff by the pressure sensor, the cuff pressure at the time when the amplitude is significantly increased is determined as the systolic blood pressure, and the cuff pressure at the time when the vibration is significantly reduced is determined as the diastolic pressure. Determined as blood pressure. The determined systolic blood pressure and diastolic blood pressure are blood pressure data. The detection signal from the cuff 10 is detected by a signal pressure sensor indicating the air pressure inside the band-shaped bag body 12 of the cuff. The measurement unit 201 that measures blood pressure supplies the result of the blood pressure determination to the cuff pressure data to the arithmetic and control unit 202 as blood pressure data. When measuring the pulse wave, the measuring unit 201 supplies the cuff pressure data to the arithmetic and control unit 202 as pulse wave data.

  The arithmetic control unit 202 includes an arithmetic processing unit and a storage device. The arithmetic control unit 202 executes a control program stored in advance in the storage device in accordance with an input signal from an operation unit (not shown). Controls the operation of the device to realize each function of the device. In particular, the arithmetic control unit 202 controls the measurement execution timing of the measurement unit 201 and receives blood pressure data from the measurement unit 201. The arithmetic control unit 202 stores the received blood pressure data in the memory 203 as readable data. The arithmetic control unit 202 converts the received blood pressure data into display data for display on a display unit (not shown) as visual information such as characters and waveforms, and outputs the display data to the display unit. Note that the blood pressure data to be converted may be data read from the memory 203. The arithmetic control unit 202 can supply the received blood pressure data and the blood pressure data read from the memory 203 to the communication unit 204.

  The memory 203 is a storage device, and can hold blood pressure data input from the arithmetic and control unit 202.

The communication unit 204 can transmit the acquired blood pressure data to an external device by the arithmetic control unit 202. Specifically, the communication unit 204 is a communication module that can communicate the acquired blood pressure data using a wireless communication method such as Bluetooth (registered trademark) or wireless LAN (Wi-Fi). That is, the same communication module is provided in another biological information collecting device such as a bedside monitor or a telemeter, and the blood pressure data is transmitted from the biological information measuring device 100 to another biological information collecting device such as a bedside monitor or a telemeter. Can be sent in real time. In addition, the blood pressure data may be transmitted to another biological information collecting device by wire.

Are formed on the outer periphery of each of them with a female screw and a male screw to be fitted to each other. By screwing the male screw portion and the female screw portion, the protruding tube portion 241 of the connecting tube portion 24 and the connected portion 126 are connected so that the protruding tube portion 241 and the connected portion 126 conduct air. . Thereby, the air supply / exhaust portion 22 and the band-shaped bag body 12 can be connected to each other in conjunction with the behavior of the cuff 10 being attached to the apparatus main body 20 via the connection between the connection cylinder portion 24 and the connected portion 126.

  Further, as long as the connecting cylinder portion and the connected portion are connected in conjunction with the operation of attaching the device main body to the cuff, the attaching direction of the device main body to the cuff may be any direction. For example, in a cuff provided with a band-shaped bag, when the same device main body as the device main body 20 is slid, the connecting tube portion 24 and the connected portion 126 may be connected to each other. In this case, the cuff 10 is provided with a rail to which the apparatus main body 20 is detachably attached, and when the apparatus main body 20 is slid and moved on this rail, the connecting cylinder portion 24 and the connected It is conceivable that the parts 126 are connected. According to this configuration, the device main body 20 is attached to the cuff 10 (specifically, the band-shaped bag body 12) by simply connecting the connecting cylinder portion 24 and the connected portion 126, and at the same time, the air supply / exhaust portion 22 and the band-shaped bag body are connected. 12 can be connected to provide air communication.

  Furthermore, in the biological information measuring device 100, each of the band-shaped bag body 12 and the device main body 20 is provided with two sets of a connecting cylinder portion for connecting the band-shaped bag body 12 and the device main body 20 and a connected portion to be connected thereto. It is good also as a structure provided separately for air supply and exhaust. In this case, a valve is provided in at least one of the paths to supply and exhaust air to and from the band-shaped bag so that the band-shaped bag can be expanded and contracted. In a configuration in which a valve is provided in each of the two paths, the valve provided on the exhaust-side connecting cylinder or the connected portion is closed when supplying air, and the valve is provided on the air-supplying connecting cylinder or exhaust when discharging. The valve provided on the connected part is closed. When a valve is provided in one of the two paths for exhaust air supply, a control valve is used to appropriately control air supply and exhaust to the belt-shaped bag.

  Also, at least one of the connecting cylinder portion of the air supply / exhaust portion of the device main body and the connected portion of the band-shaped bag body of the cuff is opened when the device main body is attached to the cuff, and the connecting cylindrical portion and the connected portion to be connected are connected. A configuration in which a lid or the like for conducting air may be provided.
