Embodiment Construction

[0019] Below in conjunction with the accompanying drawings and preferred embodiments, the structural principle and specific implementation of the electronic sphygmomanometer of the present invention will be further described:

[0020] Such as figure 1 As shown, an electronic sphygmomanometer includes a housing 1 and an armband 2 for forming air pressure on the body part of the subject, and an air tube 3 is connected between the housing 1 and the armband 2 .

[0021] Such as figure 2 As shown, an air pump 4 for providing air to the armband 2 to form air pressure, an air valve 5 for exhausting or sealing the air in the armband 2, and an air valve 5 communicating with the armband 2 are installed in the housing 1, respectively. The pressure sensor 6 used to detect the air pressure in the cuff 2 communicated with the air pump 4 and the cuff 2, wherein the air in the cuff 2 is exhausted or sealed through the air valve 5 to control the air pressure in the cuff 2 . A substrate (not...

Abstract

The invention relates to an electronic sphygmomanometer. The electronic sphygmomanometer comprises an armlet, which is used for forming air pressure at a body part of a measured person, an air pump, which is communicated with the armlet and is used for providing air for the armlet to form air pressure, and a pressure sensor, which is respectively communicated with the air pump and the armlet and is used for detecting the air pressure in the armlet, wherein an air container used for buffering the airflow which flows to the pressure sensor from the air pump is arranged between the pressure sensor and the air pump, and the air container is respectively communicated with the armlet, the air pump and the pressure sensor. According to the electronic sphygmomanometer, after the air container is additionally arranged between the air pump and the pressure sensor, the air container has larger volume, the airflow can be buffered through the air container firstly, so that fluctuation of the airflow is reduced, thus the airflow becomes more stable and uniform, and then flows out of the pressure sensor, the interference on detection of the pressure sensor is reduced, and accuracy and precision of measurement of a pressure value are improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an electronic sphygmomanometer. Background technique [0002] With the rapid development of society and the increasing awareness of human health care, electronic sphygmomanometers have entered thousands of households as a necessary health care product. In addition to normally entering the armband, the airflow will also directly enter the pressure sensor, and the airflow formed by the air pump often fluctuates greatly and has poor stability, so it will interfere with the pressure sensor’s detection of the air pressure in the armband, resulting in the final The measured blood pressure values ​​are less accurate and precise. Contents of the invention [0003] The purpose of the present invention is to provide an electronic sphygmomanometer, which solves the problem in the prior art that the air flow generated by the air pump in the electronic sphygmomanometer directly...
