Description

The transfusion air intake installation

Technical field:

This utility model belongs to medical instruments field, particularly be transfusion air intake installation with the transfusion device adapted.

Background technology:

In now medical, the closed transfusion that is representative with disposable hanging bottle type transfusion device is the infusion model that extensively adopts clinically at present, usually be made up of disposable infusion bottle and disposable transfusion device two parts, wherein disposable transfusion device is made up of air inlet pipe, tube for transfusion, air filter, control valve and syringe needle again.Although this kind infusion vessel is sealed glass jars (or plastic bottle), but still need air unanimity with maintenance bottle inner and outer air pressure in air inlet pipe enters infusion bottle, feasible transfusion can be instiled smoothly, though on the transfusion device air filter is housed at present, but this ultimate filter is lower to the microgranule rejection rate below the 5um, macromole dust in the FA simply, and can't filtering to a large amount of little dust, pathogenic bacterium and the virus that exist in the transfusion environment.The air that constantly enters makes infusion bottle become Drexel bottle, and microorganism and little dust are easy to be brought in the human body by medicinal liquid, threatens patient's key health.

Summary of the invention:

The purpose of this utility model provides the air intake duct in the alternative traditional infusion device of a kind of energy, guarantees to enter the transfusion air intake installation that infusion bottle is the clean gas of virus-free, no thermal source, no pathogenic bacterium.

The purpose of this utility model be achieved in that specify as follows:

The structure of transfusion air intake installation is: the air inlet needle of respectively establishing pore on the most advanced and sophisticated lower wall is enclosed within aerofluxus needle tubing outer wall, and all be fixed on the upper wall of base, stomidium only is communicated with left side pipe in the base under the exhaust needle, establishes filter membrane in the outlet of left side pipe in the base, the airtight medicated cap of left side pipe outlet peripheral hardware in the base; The air inlet needle lower port only is communicated with the trachea upper port by the base lower nozzle, and the trachea lower port is established protective cap.

Advantage of the present utility model clearly, the transfusion air intake installation is that disposable products " the medical automatic oxygen therapy device " container produced with our unit is matching used, is full of the clean gas of aseptic, no thermal source, no pathogenic bacterium in the medical automatic oxygen therapy device.Opening protective cap in the use makes trachea be communicated with medical automatic oxygen therapy device outlet; clean gas will enter in the infusion bottle by the air inlet needle of inserting in the infusion bottle; this device is skillfully constructed; structure is uncomplicated; make easily; can replace traditional air intake duct fully, finish normal transfusion, make whole infusion process more safe and reliable.

Description of drawings:

Accompanying drawing 1 is transfusion air intake installation structure cut-away view

Accompanying drawing 2 is transfusion air intake installation vertical view

Can find out that by accompanying drawing 1 the transfusion air intake installation is made up of base 11, filtration housing 3 two parts; Establish filter membrane 10 in the base 11 left mouths of pipe, its left mouth of pipe and balance pipe 9 right-hand member sockets, balance pipe 9 left port are established airtight medicated cap 9-1; Balance pipe 9 left port also can connect as one with airtight medicated cap 9-1; In the different vertical hollow syringe needle of two length, short air inlet needle 5 is enclosed within exhaust needle 7 outsides, its lower end is fixed on the upper wall of base 11, establish air inlet 6, steam vent 8 respectively on air inlet needle 5, the exhaust needle 7 upper prong sidewalls, exhaust needle 7 lower port are communicated with base 11 left side pipes by 11 of bases, and air inlet needle 5 end openings pass through base 11 and are communicated with trachea 4; Trachea 4 end openings are communicated with filtration housing 3 upper port, filter housing 3 lower port and establish protective cap 2.

In filtering housing 3 inner chambers, establish horizontal filter membrane 12; Fixedly establish a root puncture pin 1 in filtration housing 3 lower ends.

The specific embodiment:

At first insert the bottle stopper of infusion bottle with puncture needle 1; to play pressure balance effect pricking with needle air tube 7 together with air inlet needle 5 after extracting puncture needle 1; aiming at oneself punching position inserts in the infusion bottle; open protective cap 2 then; be communicated with the gas outlet of medical automatic oxygen therapy device connecting housing 3 lower port, high-quality clean gas filters the back through filter membrane 12 again and just with in the infusion bottle has communicated.Oneself is produced medical automatic oxygen therapy device by our company, is the container of dress clean gas, the special and supporting use of this patent, and connection gets final product.

This utility model does not have specific (special) requirements in making, and the colleague those skilled in the art can implement.
