Description

Sphygmomanometer

Technical Field

The utility model relates to an acquisition device for information data required by blood pressure measurement. More specifically, the present invention relates to a sphygmomanometer for use in a blood pressure measurement situation.

Background

At present, in the aspect of non-invasive blood pressure measurement, in order to obtain information related to systolic pressure and diastolic pressure of an arterial blood vessel in a heart beating cycle, namely information data of maximum pressure generated by blood flow to a blood vessel wall when a ventricle pumps blood to an aorta during systole and information data of minimum pressure of the blood flow to the arterial blood vessel wall caused by diastole of the ventricle are obtained. The human adopts an information data acquisition device of artificial auscultation (Korotkoff sounds), electronic auscultation, oscillography (shock waves) and photoplethysmography successively.

The manual auscultation information data acquisition device is a functional device which uses a stethoscope to block or open the flow of blood in brachial artery in cooperation with the inflation or deflation of a cuff air bag. Although the manual auscultation method is the most accurate method for measuring blood pressure which is generally accepted, the reading of the method completely depends on the sensitivity and coordination degree of human hearing and vision, and the subjectivity is strong.

The electronic auscultation information data acquisition device is characterized by that on the basis of artificial auscultation device a sound sensor is implanted into the tail end of sound tube connected with stethoscope and mounted in the main machine of blood pressure measuring instrument. However, since a section of the sound tube in the device is exposed in the field environment of blood pressure measurement (the blood pressure measuring instrument is used in any clinical or unpredictable place of a medical institution), the converted information data of the sound sensor can deviate from the original information data if the sound tube is touched, shaken, rubbed or squeezed by external force during the instant or timed continuous measurement process.

The oscillography (shock wave) information data acquisition device is simple and comprises an air bag sleeve and an inflation and deflation guide tube. The method for collecting the information data comprises the following steps: the air bag sleeve belt is wound on the arm according to the position of brachial artery, and the other end of the charging and discharging conduit on the air bag sleeve belt is connected with the external port of the host machine of the oscillometric blood pressure measuring instrument. The external port is connected with an intelligent control inflator pump, an intelligent control air release valve and a pressure sensor in the host. However, the amplitude coefficient is a fixed empirical value obtained according to a big data statistical reasoning rule, and is not accurate for blood pressure measurement values of special groups (such as the elderly and patients with arrhythmia) aiming at most groups.

Therefore, the sphygmomanometer in the prior art has the advantages and the defects, and the measurement accuracy of the sphygmomanometer applied to different crowds and occasions has deviation, so that the sphygmomanometer is not suitable for medical personnel to accurately grasp data in clinic or outpatient service.
