Abstract

The invention discloses a pulse-taking instrument based on air pressure automation adjustment. The pulse-taking instrument comprises a pulse-taking device and an air pressure automation adjustment system. The pulse-taking device comprises a watchband-type connecting belt, and a sensor fixing mechanism is installed on the watchband-type connecting belt, and is composed of a flexible fixed ring which is fixed to the watchband-type connecting belt and a fixed pressing shelf which is hinged to the flexible fixed ring; three fixing nails fixedly penetrate through the watchband-type connecting belt,three gasbags cover the upper ends of the fixing nails, and pressure sensors are fixedly connected to the lower ends of all the fixing nails respectively; the air pressure automation adjustment system is composed of a single-chip microcomputer, a signal processing circuit, an air pump, three electromagnetic valves, an interface circuit and three air pressure sensors, and the single-chip microcomputer is connected with the signal processing circuit, the air pump, the electromagnetic valves, the interface circuit and the pressure sensors. By means of the pulse-taking instrument based on the airpressure automation adjustment, by automatically adjusting the air pressure of the gasbags, pulses at different depths are obtained, the pulse position information can be accurately obtained, and therepeatability and accuracy of the traditional Chinese medicine pulse-taking instrument are improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pulse diagnosis instrument automatically adjusted based on air pressure. Background technique [0002] With the development of modern science and technology and the cross-comprehensive application of multiple disciplines, the development and research of TCM diagnosis and treatment equipment continue to promote the modernization of TCM.
