AI Technical Summary

Problems solved by technology

During the cuff inflation process, since the air pump needs to continuously output airflow, the operation of the drive components will cause the airflow to continuously generate pressure ripples, which will form interference noise and affect the detection of the pressure sensor Accuracy, resulting in the final measured systolic blood pressure, diastolic blood pressure and average blood pressure and other data are prone to errors, especially inflatable blood pressure monitors

Abstract

The invention provides a gas pump capable of reducing gas-flow noises and noises, and the gas pump is applied to a sphygmomanometer. The gas pump is provided with a housing and a drive assembly whichis arranged in the housing and is connected with a motor. The gas pump is characterized by being further provided with a filter element which is of a hollow cylinder, wherein the filter element is connected to one side of the housing; a buffer gas chamber is formed in the filter element; the filter element is provided with a gas output tube which is a hollow slender circular tube; volume of the buffer gas chamber is greater than or equal to 3 cm<3>; and the gas output tube is partially arranged in the buffer gas chamber. The filter element can provide a buffer space to eliminate noises which are generated by dispelling gas flow to discharge through the drive assembly, so that measuring precision of the sphygmomanometer applying the gas pump disclosed by the invention is improved.

Description

technical field [0001] The invention relates to the field of inflatable components used in sphygmomanometers, in particular to an air pump capable of effectively eliminating airflow noise and noise, thereby improving the accuracy of blood pressure measurement and reducing airflow noise and noise. Background technique [0002] Blood pressure is one of the important indicators for determining the state of human health. The instrument used to measure blood pressure in the early days was a mercury sphygmomanometer, which was measured using the Korotkoff Method. When in use, when the cuff of the sphygmomanometer is inflated to be greater than the systolic blood pressure of the human body, the subject's arteries will be blocked due to compression. Low impact sound (Korotkoff Sounds), the systolic blood pressure can be measured by reading the reading value of the mercury manometer; when the pressure of the cuff is lower than the blood vessel pressure, the sound cannot be heard, and...
