Abstract

The invention discloses a deflation adjuster of an electronic sphygmomanometer, and belongs to the field of medical instruments. The deflation adjuster comprises a body portion. An air inlet connectedwith a sleeve belt, and an air outlet connected with the atmosphere are arranged at two ends of the body portion respectively; a rotor shaft is mounted on the body portion, and an impeller matched with the inner wall of the body portion is mounted on the rotor shaft; a friction disk is mounted on the rotor shaft located outside the body portion; an impeller rotation speed adjusting mechanism mounted on the outer wall of the body portion comprises a support, a screwing adjustment portion and an adaptive adjustment portion, and the screwing adjustment portion and the adaptive adjustment portionare mounted on the support; the screwing adjustment portion comprises a screw rod in threaded connection with the support; the adaptive adjustment portion comprises a piston cylinder mounted in the support, a piston located in the piston cylinder, and a piston rod mounted at the lower end of the piston; friction plates are mounted at free ends of the screw rod and the piston rod, and the upper end of the piston cylinder is communicated with the air inlet end of the body portion. The deflation adjuster has the advantages that the deflation speed can be flexibly adjusted, and adverse impacts ofthe pressure change of the sleeve belt on the deflation curve can be compensated.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an electronic sphygmomanometer deflation regulating device and the electronic sphygmomanometer. Background technique [0002] Electronic sphygmomanometer is a medical device that uses modern electronic technology and the principle of indirect blood pressure measurement to measure blood pressure. Electronic sphygmomanometers are divided into arm type, wrist type, and watch type. [0003] A general electronic sphygmomanometer is mainly composed of a sphygmomanometer body and a cuff. The interior of the sphygmomanometer body includes an air pump, a pressure sensor, a quick deflation valve, a deflation device, and a PCB board. connect. After the air pump fills the cuff with a certain amount of air, the air is slowly deflated through the deflation device, and the blood pressure is measured during the slow deflation of the deflation device. [0004] However, the deflation speed of th...
