Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic sphygmomanometer of the Libaronochi type, which is a non-invasive blood pressure measuring method.

Configuration of conventional example and its problems FIG. 1 is a configuration diagram of a conventional general manual electronic blood pressure monitor. 1 is a cuff, and in this cuff 1 there is a hemostatic rubber band 9.
A sound sensor 3 is provided at 2 and 3. A rubber pipe 4 connects the rubber tube 2, the rubber bulb 6, and the pressure sensor 10. The pressurizing rubber ball 5 is provided with pulp 6. When the button is pressed, the pulp 6 performs a sudden discharge operation, and when the button is not pressed, a slight discharge operation is performed. The pressure in the rubber bag 2 is detected by a pressure sensor 10, converted into a digital signal by a MU/D converter, and inputted to a microcomputer 12. On the other hand, the signal from the sound sensor 3 is amplified by the amplifier 8, the sound component is extracted by the filter 9, and the microcomputer 12
is input. The microcomputer 12 determines the blood pressure value and displays the blood pressure value on the display 13.

Next, the operation of the pulp 6 will be explained using FIG.

After turning on the power, press the button on the pulp 6 to release the residual pressure in the cuff wrapped around your arm.

This operation is especially necessary for blood pressure monitors that use semiconductor pressure sensors or the like and require zero correction. This type of blood pressure monitor corrects zero point drift due to temperature by opening the pressure system to the atmosphere and setting the pressure at that point to zero. When the air is sufficiently exhausted, a zero point correction sound will be heard and measurement preparation is complete.

Next, pressure is applied using the rubber bulb 5 to a pressure sufficiently higher than the systolic blood pressure value of the subject. When the pressurization is stopped, the microscopic function of the pulp 6 is activated and the pressure gradually decreases. Eventually, a sound is detected by the sound sensor 3 and the systolic blood pressure value is determined. The pressure further decreases and the K sound is no longer detected, and the diastolic blood pressure value is determined. When the diastolic blood pressure value is determined, upon completion of the measurement, the button on the valve 6 is pressed to suddenly discharge the blood pressure, and the pressure display becomes zero. exhaust to.

Conventionally, operating the buttons on such valves was cumbersome, especially for elderly people.

OBJECTS OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned drawbacks of the conventional method by making it unnecessary to operate a valve and making it possible to perform measurements simply by applying pressure with a rubber bulb. Furthermore, even if it is necessary to exhaust the air after pressurization, the exhaust valve will operate until the pressure reaches zero by pressing the exhaust key once, thereby providing an easy-to-handle blood pressure monitor. This is the purpose.

Structure of the Invention In order to achieve the above object, the present invention includes a normally closed rapid drainage valve communicating with the arm cuff, a slight drainage valve communicating with the arm cuff,
It is fully equipped with a manual operation of a sudden ejection key, a residual pressure evacuation control means when the power is turned on, and a complete evacuation control means that is operated every time a measurement is made or by manual operation of the sudden ejection key.

DESCRIPTION OF EMBODIMENTS Examples of the present invention will be described below with reference to FIGS. 3 and 4. FIGS. 3 and 4 are diagrams illustrating the configuration of the electronic blood pressure monitor of the present invention and the operation of the quick discharge valve. 21 is a cuff;
22 is a rubber bag, 23 is a sound sensor, 24 is a rubber pipe,
26 is a rubber bulb, 26 is a micro-drain valve, 27U blood pressure monitor body, 35
is a microcomputer. Pressure is pressure sensor 3
o and converted into a digital signal by the A/D converter 31. On the other hand, the signal from the sound sensor 23 is amplified by an amplifier 28, and the sound component is extracted by a filter 29. The sound signal of the filter 29 and the A/fl
'The blood pressure determining means 36 determines the blood pressure value based on the pressure value signal from the converter 31, and displays the blood pressure value on the display 37. The above is the same as the conventional example.

In the present invention, when the power is turned on, the power ON detection means 38 automatically
The residual pressure exhaust control means 42 operates based on the information from the residual pressure reduction detection means 39, and the residual pressure exhaust control means 42 stops based on the information from the residual pressure reduction detection means 39. On the other hand, for each measurement, the complete 111° exhaust control stage 43 moves 1/1 according to the measurement completion information, and the complete exhaust control means 43 is stopped by the 0 mHg detection means 40. Further, the complete exhaust control means 43 can also be operated by manual operation of the sudden exhaust key 34.
The information from the residual pressure exhaust control means 42 and the complete exhaust control means 43 is logically summed by the logical sum means 44 and input to the driver 33 to operate the quick discharge valve 32.

Effects of the Invention The present invention has the above-mentioned configuration and is equipped with an automatically operating emergency drainage valve, so blood pressure can be measured simply by applying pressure with a rubber bulb, and then the system automatically performs rapid drainage. This eliminates the hassle of measuring blood pressure, making it possible to provide a convenient blood pressure monitor for the elderly.
