Description

Automatic machine for artificial breathing and heart stimulation

A kind of Self-breathing, heart pressing machine belong to medical machinery, are used for breathing, sudden cardiac arrest patient's crash equipment.

Past rescue because of hang oneself, drown, get an electric shock, breathing, sudden cardiac arrest patient due to allergy and other reasons, all adopt life-kiss, and medical personnel kneel the epigastrium that rides over patient or carry out artificial heart at one's side and push, promptly inconvenient, time-consuming, the effort unhygienic again, poor effect, execute patient's arm strength varies in size in addition, the cardiac compression skills involved in the labour differ, the sagging degree of depth difference of thoracic wall when pushing, effect is quite inconsistent, and pressure is too quickly, thoracic wall sank dark, then easily made gerontal patient's fracture of rib; Crossing shallow then not reaching is enough to make heart effectively to penetrate the blood degree, so traditional artificial directly the cardiac compression salvage success rate is very low, be improve breathe, success rate that sudden cardiac arrest critical illness people rescues, need that research design is a kind of to reduce labor intensity, close the equipment of exhaling health.

Shortcoming and defect in view of above-mentioned technology, it is a kind of that this utility model provides, can improve and breathe, sudden cardiac arrest critical illness people salvage success rate and using manpower and material resources sparingly alleviates the wholesome again a kind of machinery of medical personnel's labor intensity, electronic replacement artificial respiration cardiac compression rescues breathing, sudden cardiac arrest patient's Self-breathing, heart pressing machine.

The purpose of this utility model can realize by following technical proposals: it is by the belt pulley of motor by motor, V-belt and reducer pulley drive worm type of reduction gearing and rotate, this decelerator has coaxial two output shaft with rotating speed, the active male rotor (6) of with groove is housed on one of them output shaft, roller in drivewheel (6) groove is by roller bearing (9), be fixedly connected on the depression bar (7), depression bar (7) can move in guide bearing, so along with motor rotates, depression bar just pumps according to certain rules, thereby makes the pressure head (11) that is fixedly connected on the depression bar lower end push pareordia with certain frequency; One driving gear (12) is installed on the other end output shaft of decelerator, what be meshed with it is that this speed ratio to gear of driven gear (13) is 1:4, one eccentric orfice is arranged on the driven gear, one little axle (14) is housed so this driven pulley becomes a crank again on the hole, depression bar promptly becomes connecting rod (16), connecting rod (16) one ends are hinged on the little axle, the other end is hinged on another depression bar (17), this depression bar also can move in guide bearing (19), the depression bar lower end is connected with a dull and stereotyped platen, platen contacts with air bag (18), rotation along with motor, depression bar pumps, push breathing bag, cardiac compression and breathing bag are pushed finished Self-breathing by a certain percentage simultaneously, the function of heart pressing machine.Patient's cardiac compression is pushed simultaneously with the breathing of mouth and is carried out, and pushes to make sagging 3.5～4.5 centimeters frequency per minutes of thoracic wall 60 times, to keep the body normal physiological function at every turn.

This utility model is compared with prior art:

This machine can carry out any long cardiac resuccitation; Can alleviate medical personnel's the labor intensity and the infection chance of infectious disease; Can separate and emit the hands of executing the art doctor, brain so that it is more careful, comprehensively, systematically formulate rescuing scheme, curing patient; This machine operation is easy, and starting is rapid, definite effect, and frequency and heave amplitude all can be regulated as required, and breathing and cardiac compression are carried out separately respectively, so the use of this machine will reach a new high the recovery of breathing, heart.
