Automatic adjusting type intelligent electronic sphygmomanometer

Abstract

The invention relates to the technical field of electronic sphygmomanometers, discloses an automatic adjusting type intelligent electronic sphygmomanometer and aims to solve the problem that in the prior art, the blood pressure measurement accuracy is affected due to the fact that the winding position of a cuff is prone to deviation and the tightness is difficult to control. Through the arrangement of the storage shell, the winding wheels and the optical distance measuring sensor, the double winding wheels are used for winding the cuff, manual winding is replaced, automatic winding and unwinding of the cuff are achieved, operation is simplified, the problems of non-uniform tightness and position deviation of manual winding are fundamentally solved through interval detection and automatic arm circumference recognition of the optical distance measuring sensor, and the automatic winding of the cuff is achieved through the arrangement of the pressure mechanism. Multiple air bags are used for replacing a traditional single large air bag, uniform pressure applying along the arm length is achieved, the local pressure peak value is eliminated, false blood pressure rising caused by pressing discomfort is reduced, a supporting spring in a main hose thoroughly solves the problem of air path blocking caused by bending and squeezing, it is guaranteed that the inflation and deflation linearity is controllable, and the measurement stability is improved.
