Vertical pressing pulse condition driver

Abstract

The invention relates to the field of biomedical engineering, in particular to a vertical pressing pulse condition driver. The vertical pressing pulse condition driver comprises an array pressing sensing probe, a piston, piston locking devices, a driving tank, a tension spring, an encapsulation cover, an air pipe and an inflation and deflation control device. Pressure of the driving tank is raised through inflation of the inflation and deflation control device, the piston is pushed to move downwards, locking bolt bodies of locking bolts clamp sawteeth of blocking wings under the natural elastic force action of pressure springs, the piston is stabilized at a certain position where pressure is set, precise control over touching, pressing and searching force increasing is achieved and searching operations and pressing operations are carried out precisely and separately; the pressure of the driving tank is reduced through deflation of the inflation and deflation control device, acting force with which the piston is pulled upwards is generated through tension of the tension spring, electromagnetic driving blocks of the piston locking devices are controlled to generate magnetic attraction for attraction, pushing blocks are attracted to compress the springs, the sawteeth of the blocking wings are loosened from the locking bolt bodies of the locking blots, touching, pressing and searching force reduction is achieved and the searching operations and the pressing operations are achieved. Touching, pressing and searching pulse-taking of cun, guan and chi parts can be flexibly achieved.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a pulse condition vertical pressing driver. Background technique [0002] Since the 1950s, a large number of scientific researchers have carried out a lot of research work on pulse theory, pulse diagnosis methods, clinical diagnosis and experiments, and made great progress. Up to now, the research on the objectification of pulse condition mainly focuses on the development of pulse condition instrument. [0003] The British Marey first developed the lever pulse sensor and recorded the radial artery pulse wave. In 1860, the lever and pressure drum first appeared to describe the pulse map. In 1895, the energy conversion method was used, and the lever optical pulse descriptor appeared. In the 1950s, Zhu Yan, a Chinese scholar, introduced the lever pulsograph for the first time in the study of TCM pulse diagnosis. Since the 1970s, researchers have developed a wide variety of tr...

Problems solved by technology

[0006] The existing related invention patents and researches have achieved pulse information collection to a certain extent, but there are still some deficiencies such as impreciseness and lack of layering in simulating finger pulse pulse "lifting, pressing, and searching", and the volume is too large and it is difficult to miniaturize, etc. Disadvantages, such as "a traditional Chinese medicine pulse detection system" (CN201310418535), the pulse signal acquisition device adopts a ring or ring structure, which is wrapped around the wrist, which cannot realize the lifting, pressing, and searching techniques of traditional Chinese medicine; another example is the multi-segment compound traditional Chinese medicine Although the pulse acquisition device (CN201310499382) is equipped with a "liftable arm", it can only roughly realize the three parts of "inch, guan and ruler" to cut the pulse and adjust the pressure. Adjustment can not realize the precise stratification of the pulse in modern pulse diagnosis, and lacks flexibility; also as the automatic feedback type regional pulse acquisition device (CN203388839U), a "pulse analog stick (5 mm × 5 mm in outer diameter)" is set, but The structure is complex and lacks application flexibility, and can only roughly realize pressure regulation, and cannot realize accurate stratification of the pulse in modern pulse diagnosis
