The utility model has the advantages of simple structure, convenient carryover and reliable use, and the utility model can be assembled and disassembled, and can be operated electrically and manually. The cardiac compression and the artificial respiration can be synchronously carried out, and the utility model is especially suitable for rescuing patients who are respiratory arrest at fields and basal hospitals.

Description

A kind of portable cardiopulmonary resuscitator

This utility model relates to a kind of medical first aid apparatus that the sudden cardiac arrest patient is carried out people's mouth breathing and cardiac compression stimulation.

Heart beating, respiratory arrest be put down, critical emergency case that wartime is common, also may concentrate generation, occur in batch, thereby cardio-pulmonary resuscitation always is counted as the basic fundamental of first aid.To be that medical personnel are free-hand carry out cardiac compression and mouth-to-mouth artificial respiration to traditional method for resuscitation, and this kind method rescues not only that personnel labor intensity is big, efficient is low, and specification requirement height, misoperation easily cause the chest rib fracture.

Now have the patent of a collection of cardio-pulmonary resuscitation machine, as " portable heart and brain resuscitating machine " (ZL941167.6), " portable field cardiopulmonary resuscitator " (ZL90219180.2), " manual device for resuscitating heart and pulmones " (ZL912057.31 etc., they mostly adopt the leverage principle, finish the work of pushing heart by operator's action bars that fluctuates, can not electricity consumption operate: and " portable external cardio-pulmonary resuscitation machine " (ZL862027461, " Self-breathing, heart pressing machine " (ZL942320261 etc., complex structure, install, carry inconvenience, again can only electric operating.

The purpose of this utility model aim to provide a kind of not only can be electronic but also can be manually, cardiac compression and artificial respiration can work in coordination with carry out, the portable cardiopulmonary resuscitator of fast demountable, easy pushing and carrying.

The implementation of this utility model purpose is that a kind of portable cardiopulmonary resuscitator comprises column 17, crank 11, motor 12, cardiac compression and artificial respiration mechanism.Rotatable girder 16 is sleeved on the column 17, dress main shaft 1 on the girder.Main shaft 1 is by column one end assembled cranking bar 11, top dress motor 12, decelerator 13, use chain between the sprocket wheel (10) on the reducer shaft on institute's peace sprocket wheel 14 and the main shaft) 5 be connected, the middle dress of main shaft driving gear 5 reaches the driven gear 6 with its engagement, and the cam 7 that is compounded on the driven gear 6 directly contacts with the pressing plate 8 of breathing bag 9.The other end dress cam 2 of main shaft 1, cam 2 is pressed in by spring 22 on the depression bar 3 that is loaded in the guideway, 3 times dresses of depression bar rubber pressure head 4.

This utility model is described in detail in detail with reference to the accompanying drawings.

With reference to accompanying drawing, human body to be faced upward on the strip base plate 19 that is placed on vertical columns 1, rotation is after girder 16 adjusts the position of depression bar 3, with lock screw 18 girder is locked on the column.The length of depression bar 3 is regulated by the lower end snail swing arm, and screw rod links to each other with rubber pressure head 4 by universal joint 21, and pressure head has bowl-type, and shapes such as sphere or simulation palm shaped are to adapt to the patient of different builds.When the rubber pressure head transfers to after need are pushed the suitable position of skin surface, lock the position that initially presses down by locking nut 20.

Main shaft 1 is connected with chain 15 by 10 on the sprocket wheel on institute's peace sprocket wheel 14 on column 17 1 end assembled cranking bars 11. tops dress motor 12, decelerator 13, the reducer shaft and the main shaft, therefore when connecting motor power or shaking crank 11, main shaft 1 rotation, the work of this resuscitator, this resuscitator can be electronic, manually carry out respectively, also can carry out simultaneously, not disturb mutually.

Main shaft 1 rotation, the cam 2 that drive is contained on the main shaft rotates, cam 2 forces depression bar 3 to push the thoracic cavity downwards by rubber pressure head 4, push at every turn and can make the chest wall 3.5-4.5cm that sink, compression frequency can be controlled between per minute 55-65 time, lifting on the depression bar 3 is to realize by spring 2, presses the motion of the lifting contour curve decision by cam 2 under the depression bar.Contour curve divides three sections, and cam angle is even lift section for 0 °-135 °, makes depression bar at the uniform velocity press down lift, and 135 °-270 ° are at the uniform velocity backhaul section, makes depression bar 3 lift backhaul at the uniform velocity, and 270 °-360 ° for stopping the journey section, and depression bar does not move, and stops journey.

In to cardiac compression, generally to practice artificial respiration to patient.Breathing bag 9 is connected to face shield or inserts the trachea in patient nostril.When main shaft 1 rotation, when cam 2 forced depression bar 3 to push the thoracic cavity by rubber pressure head 4, driving gear 5 rotated thereupon, because driven gear 6 and driving gear 5 engagements, its rotating ratio is 1: 5, and cam 7 is compounded on the driven gear, therefore main shaft whenever rotates five circles, and cam 7 rotates a circle.The contour curve of cam 7 constitutes by two sections, be that cam angle is even lift section from 0-240 °, 240 °-3 60 ° is even backhaul section, this design meets artificial respiration's requirement, be that cam rotates 2/3 o'clock pressing plate 8 and evenly breathing bag calmed the anger, gas is charged into the human lung, breathing bag inflated in 1/3 o'clock, and this moment, patient freely exhaled.

This utility model can be with metal or engineering plastics manufacturing, gross weight＜15 kilogram.Base plate, column, girder, crank, breathing bag etc. are fast demountable all, and dismounting is placed in the suitcase of band roller, and is easy to carry.

This utility model adopts two cover cam follower structures, and the curvature of cam designs to such an extent that meet heart of patient is pushed requirement with the artificial respiration.This utility model not only can be electronic but also can be manual, and electric and hand also can carry out simultaneously, and the parts fast demountable is easy to carry, so this utility model is particularly suited for open-air, the heart of basic hospital, the patient of respiratory arrest are implemented to rescue.
