Description

Volum-controlled type simple respirator

Technical field: this utility model relates to a kind of improvement of simply respirator.

Background technology: simply respirator also claims ball or breathing bag clinically, is used for critical patient's urgent rescue and assisted respiartion.The machine of breathing no more and need assisted respiartion or because of have a power failure, under the situation of respirator fault or on-the-spot interim rescue etc., simply respirator just becomes the only resource that carries out artificial ventilation to patient.Existing simply respirator mainly is divided into two kinds of child and adults, but no matter which kind of, its primary structure is exactly that two valves (air inlet, give vent to anger) add an approximate ellipsoidal rubbery human body, mediates sacculus by the medical worker with hands during use and makes patient obtain ventilation.There is following drawback in use in existing breathing bag: (1) patient body weight difference, required tidal volume (respiration is given tolerance) difference, and have now on the simply respirator without any capacity control device, ventilation is grasped with sensation, experience by the operator, therefore ventilation is extremely inaccurate, in a short time still can, prolonged application then can be because of the too much or very few patient's life that jeopardizes of ventilation.(2) user of service's hand-type varies, and can not guarantee ventilation accurately; Each extruding dynamics difference gives tolerance also inequality; Same patient, same breathing bag is used by different medical personnel, gives tolerance all inequality, influences patient's rescued effect.

Summary of the invention: the purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of ventilation volum-controlled type simple respirator more accurately is provided.

This utility model includes breathing bag, handle and clip, fixed bar and scale; Handle includes fixed handle and moving handle, and fixed handle is connected with breathing bag by clip respectively with moving handle, and breathing bag has one section foldable section between fixed handle and moving handle.Moving handle is provided with the hole, can pass for fixed bar and scale respectively, and the scale high scale is a human body body weight number, and the scale edge is provided with teeth, and the card wheel is housed on the scale, is equipped with the female thread that matches with scale edge teeth in the card wheel; The card wheel rotates and just can move along scale.

For increasing the memory of breathing bag, between fixed handle and moving handle, be provided with spring, spring housing is on fixed bar, and both ends of the spring is separately fixed on fixed handle and the moving handle.For conveniently holding, also be provided with flexible handle, flexible handle is contained on the moving handle by pin.

This utility model for pusher, according to patient body weight, will block the improvement of former kneading type operation principle on wheel and be threaded to corresponding body weight value sign place during use, and user is pulled handle extruding breathing bag to fastening scale place, be this body weight patient once to tolerance.

The utility model has the advantages that: (1) this breathing bag in case of emergency still can equally with former breathing bag be mediated use, does not influence the urgent use under the emergency case.(2) the disposable tolerance of giving is comparatively accurate, life-time service can not occur because of ventilation is inaccurate bring between topic.(3) ventilation can be because of the significant change of user difference.Flexible handle is adjustable, is applicable to the not user of homochirality size.

This utility model is applicable to critical patient's urgent rescue and assisted respiartion.This utility model product can be designed to two types of adult, children's.

Description of drawings: accompanying drawing is this utility model structural representation.

The specific embodiment: fixed handle 8 is connected with breathing bag 11 by clip 13 respectively with moving handle 4, and breathing bag 11 has one section foldable section 10 between fixed handle 8 and moving handle 4.Moving handle 4 is provided with the hole, can pass for fixed bar 14 and scale 6 respectively, and scale 6 edges are provided with teeth, and card wheel 7 is housed on the scale 6.For conveniently holding, also be provided with flexible handle 5, flexible handle 5 is contained on the moving handle 4 by pin 3.Be respectively equipped with air inlet 1 and gas outlet 9 on the breathing bag 11, so that be connected with tracheal intubation with oxygen hose respectively.

Air inlet

1 and 9 places, gas outlet at breathing bag 11 are equipped with check valve 12.For preventing moving handle 4 slippages, be equipped with plug 2 in the outer end of fixed bar 14 and scale 6.Be provided with spring 15 between fixed handle 8 and moving handle 4, spring 15 is enclosed within on the fixed bar 14.
