Abstract

The utility model relates to a transfusion air inlet device. The utility model is composed of a base, a protective cap, a connecting casing, an air tube, an air inlet needle, an air exhaust needle, a sealing cap, a filter membrane and a puncture needle. The advantage of the utility model is obvious. The transfusion air inlet device is matched and used with a container for a 'medical automatic oxygen transfusion device', which is a disposable product produced by the unit. The medical automatic oxygen transfusion device is filled with clean gas having the characteristics of asepsis, no heat source, and no pathogenic bacteria. The utility model has the advantages of artful design, simple structure and easy fabrication. The utility model can completely substitute for the traditional air inlet tube, and the normal transfusion can be completed. The entire transfusion process is safe.

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: respectively establish the exhaust needle of pore on the most advanced and sophisticated lower wall, the lower end of air inlet needle is separately fixed at the upper wall of base, stomidium is communicated with left side pipe in the base under the exhaust needle, establish 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 is communicated with the trachea upper port by base, 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 by accompanying drawing 1, establish the left mouth of pipe and lower nozzle in the base 11, for the ease of making and using, in the left mouth of pipe, establish filter membrane 10, the outer socket balance pipe 9 of the left side mouth of pipe, balance pipe 9 left port are established airtight medicated cap 9-1, and airtight medicated cap 9-1 also can connect as one with balance pipe 9 left port; The lower end of exhaust needle 7 and air inlet needle 5 is separately fixed at the upper wall of base 11, establishes steam vent 8, air inlet 6 respectively on exhaust needle 7 and the air inlet needle 5 upper prong lower wall; In order to guarantee the air inlet cleaning, air inlet needle 5 lower ends are communicated with trachea 4 by base 11 inner lower tube mouths, trachea 4 lower ends be connected housing 3 connections suitable for reading, establish filter membrane 12 in connection housing 3 inner chambers, connection housing 3 lower port 3 are established protective cap 2; Insert in the infusion bottle, smoothly for the ease of exhaust needle 7, air inlet needle 5 at the fixedly connected puncture needle 1 of protective cap 2 lower walls.

The specific embodiment:

At first insert the bottle stopper of infusion bottle with puncture needle 1; to play the own punching of pressure balance effect pricking with needle air tube 7 alignings position insertion infusion bottle after extracting puncture needle 1; all insert in the infusion bottle until exhaust needle 7, air inlet needle 5; 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 just with in the infusion bottle has communicated.Medical automatic oxygen therapy device is a container of adorning clean gas, and product has been arranged, special and this patent adapted.

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