Air pump and electronic sphygmomanometer

Abstract

The invention discloses an air pump which is used for a sphygmomanometer and comprises an air bag and an air faucet. The air faucet is communicated with the air bag, an electromagnetic actuator is further connected with the air bag and comprises a coil winding and a permanent magnet block, and the air bag can be driven under electromagnetic induction movement between the coil winding and the permanent magnet block to deform and suck or squeeze air, so that air pressures can be outputted. The air pump has the advantages that electromagnetic driving modes are matched with the air bag, so that acuff air bag of the sphygmomanometer can be inflated and pressurized; the air bag in the air pump can periodically deform in expansion and contraction manners and is matched with the air faucet, accordingly, the air can be sucked, and the air pressures can be outputted; electromagnetic induction effects can be realized by the coil winding and a permanent magnet, and rotors can periodically move, so that the air bag can be compressed or stretched and can be inflated and deflated; rubbing and collision between mechanical components of a driving air pump in the traditional design can be prevented, noise generated when equipment works can be lowered to a great extent, and accordingly the technical problems of inaccurate blood pressure detection results easily caused by noise interference can be solved. The invention further discloses the electronic sphygmomanometer.

Description

technical field [0001] The present invention relates to the technical field of medical care equipment, more specifically, to an air pump, and also to an electronic sphygmomanometer. Background technique [0002] Changes in life have caused most people to be in a sub-health state. At the same time, the increase in human activities has led to an increase in personal safety accidents. Therefore, human health detection methods need to be continuously developed and enriched, for example, a blood pressure monitor is one of them. Blood pressure indicators are very important to human health, so blood pressure measurement equipment requires continuous improvement. [0003] The important parts of electronic sphygmomanometer are cuff air bag, pressure sensor, air pump solenoid valve and controller. The process of measuring blood pressure includes the process of rising air pressure and the process of falling air pressure, and the detection of blood pressure is carried out during the p...
