Abstract

The utility model relates to a hand-control oxygen supply device used alternately with closed cardiac pressing, which is a simple and manual salvage instrument. The utility model is composed of an oxygen cylinder (1), a connecting pipeline (4), an air guide tube (5), a suction cup (6), a ring for hitching a hand (7), and an elastic sealed cap (9) which can cut a passageway for outputting oxygen (8) by a protuberance (10). During first aid, the suction cup is pushed in order to compress a thoracic cavity, and meanwhile, achieves the aim of assisting lung expiration and heart output blood, the protuberance which is on the sealed cap cuts the passageway to stop supplying oxygen; the suction cup is pulled in order to expand the thoracic cavity forcibly, and meanwhile, achieves the aim of assisting lung inspiration and heart blood refluence. The protuberance returns to the original state to unclog the passageway for oxygen supply, and cardiopulmonary resuscitation can be realized. The better effect can be obtained when the airway is connected with a high-frequency spray head.

Description

With the alternative manual oxygen supply of external chest compression

This utility model belongs to technical field of medical instruments, be a kind of can to patient's breast press outward by and replace the medical equipment of manual oxygen supply, assisted cardiopulmonary resuscitation.

In the daily life,, be symptom the most critical in the emergency case because of many reasons cause the human body sudden cardiac arrest.In order in time to carry out salvage at scene, traditional method is to carry out life-kiss and free-hand closed cardiac massage.Along with development of technology, various structure advanced persons, multiple functional respiratory resuscitation device successively come out, and have rescued critically ill patient effectively, but these devices are because complex structure, need higher operating technology and some necessary complementary conditions, be difficult to rescue in scene or the way.It is a kind of simple that the cardiopulmonary resuscitator that Chinese patent ZL95236029.2 external chest compression and artificial ventilation hocket provides, can be for the device of home care operation, it is by the external chest compression sucker of band cover hands circle, and oxygen cylinder, composition such as electromagnetic valve and pipeline, push suction by staff and be attached to the outer sucker of breast, the compression thoracic cavity makes heart row's blood and helps pulmonary's aerofluxus, when stopping to push and lifting sucker thereupon, sucker initiatively lifts expanded chest because of vac sorb, help two pulmonary aspirations and venous return heart, staff lift draw in, because of shake-up is installed in microswitch on the sucker, start electromagnetic valve to the human airway oxygen supply, since artificial initiatively compression and expanded chest, and when expanded chest, be able to synchronous oxygen uptake, can accelerate patient's cardio-pulmonary resuscitation effectively undoubtedly.But this resuscitator needs the adapted power supply, the trouble that in emergency circumstances seems, and structure simplification inadequately still, and cost can not further descend.

This utility model is at the deficiency of above-mentioned technology, its task is a kind of further simplified structure of Development and design, and outside pushing breast the manual source of the gas that cuts off in the sucker, recover oxygen supply with manual in the sucker outside lifting breast, make be suitable for average family standby and operation, can with the alternative manual oxygen supply of the external chest compression product that comes true.

This utility model mainly by oxygen cylinder, pressure regulator valve, air gauge, duct coupling, airway and pressing sucker and at the bottom of being contained in sucker cover hands circle of outside etc. constitute, unusual part is in the pressing sucker bottom oxygen therapy passage is arranged, the inlet end of oxygen therapy passage joins with duct coupling and oxygen cylinder, outlet side and airway join, and the elastic force capping is equipped with in the sucker bottom, is associated with the projection that can cut off the oxygen therapy passage in the capping.

Its technical pattern also can comprise: the oxygen therapy passage in the sucker bottom is a rubber-like pipe, and is associated with the projection that can flatten the elasticity pipe in the elastic force capping.Airway can be more successively with the open high frequency jet head of band ejector pin and grid hole connection seat, and tracheal intubation link.

The oxygen supply of this structure has following effect: 1/3rd intersections under aiming at pressing sucker in patient's breastbone during use, rescue personnel's a palm pierces in the cover hands circle, another palm is pressed in the auxiliary pressurization of cover hands figure outward, open oxygen cylinder simultaneously, and airway inserted patient airway (nose or mouthful in), when the rescue personnel pressurizes with hands, discharge air in the sucker earlier, sucker is adsorbed on outside the thoracic cavity, compress the thoracic cavity then, make heart row's blood and two lung aerofluxus, meanwhile, along with palm pressurizes to the sucker bottom, at first pass the elastic force capping, projection on it is moved down, thus the stifled oxygen therapy passage that cuts off in the sucker bottom of resistance; When palm is lifted when carrying cover hands circle, make on the sucker absorption thoracic cavity and carry and expanded chest, promote the venous return heart and help two pulmonary aspirations, meanwhile, break away from the elastic force capping when proposing on the palm, elastic reset along with capping, projection on it upwards resets together, makes the oxygen therapy passage of sucker bottom keep unimpeded, and oxygen sprays from airway, help patient's oxygen uptake, this oxygen supply program, neither with patient's antagonism of exhaling, again can oxygen supply when the patient is air-breathing, because the patient forces to exhale and force oxygen supply air-breathing without a break repeatedly, thereby impels cardio-pulmonary resuscitation as early as possible.If airway is associated with after the high frequency jet head joins the intubate of inserting trachea again, then when the airway oxygen supply, can sneak into a large amount of outside airs from the high frequency jet head, strengthened pulmonary air flow, abundant oxygen supply and ventilation have been guaranteed, and the negative pressure that produces helps venous return, further accelerates patient's cardio-pulmonary resuscitation effectively.

Fig. 1 is this utility model structural representation.

Fig. 2 is that this utility model oxygen therapy passage is the structural representation of elasticity pipe.

Fig. 3 is the structural representation that airway is associated with the high frequency jet head.

From the visible this utility model of Fig. 1 mainly by oxygen cylinder (1), pressure regulator valve (2), air gauge (3), duct coupling (4), airway (5), pressing sucker (6) and at the bottom of being contained in sucker cover hands circle (7) of outside etc. form.Sucker has oxygen therapy passage (8) in the bottom, and its inlet end and duct coupling (4) join, and its outlet side and airway (5) join, and bottom the sucker elastic force capping (9) is housed, and is associated with the projection (10) that can cut off the oxygen therapy passage in the capping.

Fig. 2 has represented the frame mode of the oxygen therapy passage that a kind of employing elasticity pipe (8 ') constitutes, when palm pressing sucker (6) bottom, pass elastic force capping (9) earlier, flatten elasticity pipe (8 ') by the projection (10 ') on it, thereby push the thoracic cavity at sucker, cut off oxygen supply when helping the aerofluxus of people's lung, otherwise projection (10 ') return recovers pipeline (8 ') oxygen supply when lifting sucker, help people pulmonary aspiration.

Fig. 3 is the connection figure that airway (5) connects band ejector pin (11), grid hole connection seat (12) and person's windpipe intubate (13), thereby can quicken patient's cardio-pulmonary resuscitation by the logical oxygen mode air feed of high frequency jet.

If by shown in Figure 2, be provided with the outgassing nonreturn valve (14), breather check valve (15) and the valve (16) that communicate with sucker (6) inner chamber, then when the pressing sucker first time (6), the air of sucker inner chamber, can make sucker tightly be adsorbed on outside the breast from outgassing nonreturn valve (14) row to the external world; Finish to take off sucker the time in rescue,, just can make outside air enter the sucker inner chamber, thereby the placement of sucker and take off more conveniently feels comfortably cool patient through breather check valve (15) as long as open valve (16).Obviously the sucker that has valve (14,15) structure only needs suitable repacking promptly to become a kind of vacuum extractor, can be used for sick bed and attract expectorant class dirt.
