Novel mechanical blood pressure meter movement

Abstract

The invention relates to a novel mechanical blood pressure meter movement. The movement is characterized in that the blood pressure meter movement is composed of a lower box cover, an ejector pin, a gear assembly, a pointer shaft, a torsion spring and an upper box cover. The ejector pin is arranged on the gear assembly, the pointer shaft is sleeved with the torsion spring, and the gear assembly is arranged between the upper box cover and the lower box cover which are fixed together through a buckle structure. According to the technical scheme, the overall structural design is ingenious, and the structure is compact and simple. Main parts of the movement are made of plastic good in forming performance. The mechanical blood pressure meter movement is optimized through the brand new design suitable for characteristics of the plastic parts, production efficiency is greatly improved, and performance is more stable.

Description

technical field [0001] The invention relates to a sphygmomanometer movement, in particular to a novel mechanical sphygmomanometer movement, which belongs to the technical field of medical equipment. Background technique [0002] With the development of economy and social progress, people's awareness of health and self-care has been continuously improved, and people's requirements for living environment, personal health care, medical treatment, etc. are getting higher and higher. Sphygmomanometer is a kind of indirect measurement method. The mechanical sphygmomanometer is convenient and quick to use, and is widely used day by day. [0003] Mechanical sphygmomanometer is a medical device used with stethoscope to measure human blood pressure. It consists of movement, bellows, dial, pointer and case. Among them, the diaphragm box converts the gas pressure to be measured into mechanical displacement, and the movement converts the mechanical displacement generated by the diaphrag...

AI Technical Summary

Problems solved by technology

[0004] The movement installed in the watch case is the core component of the mechanical blood pressure gauge. The movement converts the mechanical displacement generated by the bellows into the mechanical rotation of the gear shaft. The traditional movements all use metal parts, and the processing technology of metal parts There are many, and the shape of parts is limited by the processing technology, resulting in a large number of parts, low production efficiency, high manufacturing cost, low displacement-rotation conversion efficiency, complex assembly of the movement, and the open movement does not have dustproof performance and other insurmountable obstacles. Therefore, There is an urgent need for a new technical solution to solve this technical problem
