Abstract

The utility model discloses a sphygmomanometer, which comprises an air guide pipe, an air bag, an elastic cuff with an air inflation cavity, a sensor, a loudspeaker, a wire, headsets, a piezometer tube and a piezoresistive force sensor, wherein the air bag is connected with the elastic cuff with the air inflation cavity through the air guide pipe, and the elastic cuff is connected with the piezoresistive force sensor through the piezometer tube. The sphygmomanometer disclosed by the utility model is novel in design and is not easy to fall off because the elastic cuff with the air inflation cavity is directly sleeved on the arm of a patient in the using process; and the piezoresistive force sensor can directly display the pressure value so as to avoid reading errors caused by self reasons of an operator, so that the blood pressure can be measured more accurately and the additional value of the sphygmomanometer is increased.

Description

A kind of sphygomanometer

Technical field

This utility model belongs to the medical treatment device class, particularly a kind of sphygomanometer.

Background technology

Along with the extensive use of sphygomanometer, some new problems also occur thereupon, and the cuff of existing sphygomanometer is fixed with thread gluing usually, and when patient's hyperpiesia and cuff were full of gas, the thread gluing on the cuff got loose easily gradually, causes measurement error large.General sphygomanometer all is to adopt gauge hand to show reading, because the people always overlooks dial reading, produces easily artificial error in reading, measures the incorrect of posture when this kind reading mode also causes Measure blood pressure easily.

The utility model content

For the problem that above-mentioned prior art exists, this utility model provides a kind of sphygomanometer in order to remedy the deficiencies in the prior art.

To achieve these goals, the technical solution adopted in the utility model is: comprise airway, air bag, with the elasticity cuff of inflatable chamber, sensor, microphone, wire, earphone, pressure-measuring pipe, piezoresistive force sensor, described air bag joins by airway with the elasticity cuff of inflatable chamber, elasticity cuff with inflatable chamber is connected with piezoresistive force sensor by pressure-measuring pipe, on the elasticity cuff with inflatable chamber sensor and microphone is housed, and microphone directly links to each other with earphone by wire.

By use can directly be inserted in patient's arm with the elasticity cuff of inflatable chamber and the direct piezoresistive force sensor of display of blood pressure value size, allow air bag join by airway with the elasticity cuff of inflatable chamber, the elasticity cuff is connected with piezoresistive force sensor by pressure-measuring pipe.

Compared with prior art, the utility model has the advantage of: modern design, elasticity cuff with inflatable chamber in use directly is enclosed within on patient's arm, difficult drop-off, the pressure sensing instrument can directly demonstrate the force value size, make the posture of operator when measuring more proper, the error in reading of having avoided operator's self reason to produce makes blood pressure measurement more accurate.And this utility model is easy to use, and is simple in structure, is convenient to produce.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As a kind of embodiment of the present utility model, consult Fig. 1, this utility model comprises airway (1), and air bag (2) is with the elasticity cuff (3) of inflatable chamber, sensor (4), microphone (5), wire (6), earphone (7), pressure-measuring pipe (8), piezoresistive force sensor (9).Air bag (2) joins by airway (1) with the elasticity cuff (3) of inflatable chamber, and elasticity cuff (3) is connected with piezoresistive force sensor (9) by pressure-measuring pipe (8).

In use, operator at first are enclosed within elasticity cuff (3) on patient's the arm, put on earphone (7), then pass through the gently interacvity air-filling of the past elasticity cuff (3) of extruding gasbag (2), record corresponding pressure value with the pressure-measuring pipe (8) that elasticity cuff (3) directly links to each other, send piezoresistive force sensor (9) to, and in the corresponding pressure value size of the upper directly demonstration of piezoresistive force sensor (9), conveniently read.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use this utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, General Principle as defined herein can the situation within not breaking away from spirit or scope of the present utility model under, realize in other embodiments.Therefore, this utility model will can not be limited to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
