The utility model consists of an infusion bottle inserting needle, an oxygen inlet pipe, an oxygen filter, an air filter type liquid medicine filter and a rubber sleeve; the infusion bottle inserting needle, the oxygen inlet pipe and the air filter type liquid medicine filter are connected together by a three-way, the oxygen filter is arranged at one end of the oxygen inlet pipe, and the rubber sleeve is arranged at a connecting pipe which is arranged at the lower end of the air filter type liquid medicine filter main body. The device has flexible operation and usage, which is safe and convenient, the air filter type liquid medicine filter on the utility model can absorb the harmful insoluble particles and pyrogens in the liquid medicine, eliminate the bubbles formed in the infusion at any time or eliminate the residual oxygen after the infusion, ensure that the air does not enter the vein and the air embolism can not be generated.
Description
Technical field: the utility model discloses a kind of medical apparatus and instruments, give the used air filter of medicinal liquid oxygenation during a kind of specifically transfusion the---oxygenation transfusion safety filter gas bucket.
Background technology: at present, the transfusion device of using in hospital all is common disposable transfusion devices, it is made of tube for transfusion, outgas pipe, slotting bottle head, syringe needle, the negative pressure that enters in the infusion bottle to be produced by the outgas pipe in when transfusion, suck air, medicinal liquid is injected in the human body by tube for transfusion, and the shortcoming of this infusion model is might airborne various dust impurity bands are into the liquid.In real society, people pay much attention to healthy, atmospheric pollution has brought many harm for people's life and health, people often reach the intake of oxygen by modes such as oxygen bar or the oxygen uptakes of oxygen storehouse, the shortcoming of this mode is that the consumption of oxygen is bigger, and it is fewer to enter into the oxygen of blood.Some are also arranged in order to prevent cardiovascular and cerebrovascular disease, blood is extracted out, annotate again through oxygenation and get back in the blood vessel,, bring unnecessary misery to people though improved the oxygen content in the blood.
In order to solve the aforesaid drawbacks, the inventor has applied for that application number is 00252478.3 " oxygenation transfusion device ", number of patent application is 01211856.7 " circumscribed oxygenation transfusion device ", number of patent application is 01219789.0 transfusion, blood transfusion oxygenation pipe, number of patent application is 01241094.2 oxygenation transfusion device, the structure of above-mentioned four kinds of products is to adopt common disposable transfusion device and common air filter, although on principle, solved the problem of transfusion oxygenation, on safe in utilization, still there are some defectives on the aseptic transfusion effect with guaranteeing.Above in addition various patents structurally can't be got rid of the bubble that forms in the transfusion or the remaining oxygen when finishing of infusing at any time, are easy to produce aeroembolism.
Summary of the invention: the purpose of this utility model is will provide a kind of can guarantee that when oxygenation is infused oxygen can not enter human body by tube for transfusion and form aeroembolism, have again simultaneously from degassing function, simple in structure, use safer air filter---oxygenation transfusion safety filter gas bucket.
The purpose of this utility model is achieved in that this oxygenation transfusion safety filter gas bucket comprises infusion needle, oxygen intake pipe, oxygen filter, air-filtering type liquid medicine filter and rubber sleeve, link together by a threeway between its infusion needle, oxygen intake pipe and the air-filtering type liquid medicine filter, oxygen filter is arranged on an end of oxygen intake pipe, and rubber is sheathed
Put on the lower end connection tube of air-filtering type liquid medicine filter main body.
Described air-filtering type liquid medicine filter adopts tubular and two kinds of forms of flat ellipticity.
Described tubular air-filtering type liquid medicine filter is made of filter body and filter upper shield, its filter body is a tubular structure that has a plurality of boss on it, the middle part has an annular groove, on groove, have a liquid collecting hole, medicinal liquid delivery outlet below liquid collecting hole connects, have an air inlet above, have an air vent and medicinal liquid delivery outlet below, gas phase membrane is arranged on the air inlet place; High density liquid phase Membrane cover is contained between filter body and the upper shield, is provided with the medicinal liquid input port above the filter upper shield.
Described flat ellipticity air-filtering type liquid medicine filter is made of filter base and filter cover, on the base of filter, be processed with a plurality of liquid baths, have a delivery outlet under it, high density liquid phase film is arranged between the base and loam cake of filter, above filter cover, be provided with the input port, have a steam vent above, gas phase membrane is arranged on the steam vent place.
This utility model is a kind of air filter that plays the effect of safety filter gas in the process of oxygenation transfusion, and this device is operated and used flexibly safe ready.But harmful insoluble microparticle and pyrogen in the air-filtering type liquid medicine filter absorption medicinal liquid on it, and can momentarily get rid of the bubble that forms in the transfusion or the remaining oxygen when finishing of infusing, guarantee that gas can not enter vein, can not form aeroembolism.
