Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic blood pressure monitor having an automatic pressurization device with a pressurization target value setting function and an automatic exhaust device, and particularly relates to an underpressurization correction device thereof.

(Configuration of conventional example and its problems) Figure 1 shows the progress of the pressure value inside the cuff and the operating status of the exhaust device and pressurization device when insufficient pressurization occurs in this type of conventional automatic blood pressure monitor. It is.

In the conventional example, when insufficient pressurization occurs, the pressurizing device operates and pressurizes to a certain pressure value higher than the pressurization target set by an external switch or the like.

This cumulative method of underpressure correction increases the feeling of tension as the subject's arm is pressed for a long time, and it becomes impossible to measure normal blood pressure due to blood vessel congestion, etc. When a pressure shortage occurs, the above-mentioned phenomenon is magnified, causing the blood pressure value to deviate even further from the normal value.

(Object of the invention) The present invention eliminates the problems of the conventional example described above.
It is an object of the present invention to provide an underpressurization correcting device for an automatic blood pressure monitor that reduces the feeling of tension in a subject and enables prevention of blood vessel congestion.

(Structure of the Invention) In order to achieve the above object, the present invention provides an underpressure correction device for an automatic sphygmomanometer according to the present invention, which includes means for immediately exhausting empty silver in the arm cuff when underpressurization occurs, and an external The method includes a means for adding a certain amount to the pressurization target set by a switch, etc., and a pressurizing means for automatically starting re-measurement after exhaustion is performed by the exhaust means when insufficient pressurization occurs. As a feature,
This configuration eliminates tension in the subject and blood vessel congestion.

(Description of Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a block diagram showing the configuration of an underpressure correction device for an automatic blood pressure monitor according to an embodiment of the present invention.

In the illustrated configuration, when measurement is started, the pressurizing means 2 operates up to a pressure value inputted by the pressurizing target setting switch 6 or the like.

In this case, the comparison means 5 monitors whether the cuff internal pressure value 4 has reached the pressurization target setting value 6, and when the pressure value 4 has reached the pressurization target value 6, information is sent to the pressurization means 2 and the operation of the pressurization means 2 is stopped.

When the pressurization is stopped and measurement is started, the pressurization insufficiency determining means 7 is activated to determine whether the pressurization is appropriate.

When insufficient pressurization occurs, this information is sent to the exhaust means 3, and the exhaust means is immediately activated to exhaust the air inside the cuff. Information regarding insufficient pressurization is also sent to the pressurizing means 2, and preparations are made to set a one-hour rest period after evacuation and to automatically start pressurizing for re-measurement. When insufficient pressurization occurs, the pressurization target value adding means 1 is activated, and the pressurization target value for re-measurement is determined.

With such a configuration and operation, the course of the pressure value inside the cuff and the operations of the exhaust means and the pressurizing means are as shown in FIG. 3. In other words, when insufficient pressurization occurs, - exhaust the air in the carrier arm cuff,
By starting the re-measurement after a few seconds of rest and pressurizing at a constant ΔP higher than the previous pressurization target value, the test subject's arm is not pressed continuously for a long period of time, and the feeling of tension is removed. It prevents blood vessel congestion.

(Effects of the Invention) The present invention has the above-described configuration and operation, and provides the following effects.

(&) By not having to press the patient continuously for a long time, and by taking a break for a few seconds before starting automatic re-measurement, it is possible to remove the patient's nervousness and accurately calculate the normal blood pressure value. can be measured.

(b) Congestion can be prevented because blood vessels are not compressed continuously for a long period of time.
