Description

A kind of secondary filter type automatic liquid-stopping transfusion apparatus

Technical field

The utility model relates to infusion apparatus technical fields, and in particular to a kind of secondary filter type automatic liquid-stopping transfusion apparatus.

Background technique

People's living standard is gradually increased in recent years, and year by year increasing of the country to medical treatment investment, more and more tools The medical treatment consumptive materials of standby specific function are used among treatment, and automatic liquid-stopping transfusion apparatus is flat also by more and more extensive due to valence of fine quality Use.

But the defect of existing infusion is mainly infused pollution, and transfusion instrument and drug itself are existed and defeated The foreign matter generated during liquid enters human body with medical fluid together, causes adverse reaction.The pollution is mainly particle, i.e., partial size is 50 The granule foreign that μm insoluble naked eyes below can not be observed.Into after human body, on the one hand particle can cause blood vessel bolt Plug and local tissue necrosis, have blood vessel blockage and damage cause oedema and inflammation etc. generate, cause phlebitis, artery sclerosis or Person's pyrogen sample adverse reaction;Granulation is easily caused after another aspect foreign matter particle deposition to the tissue capillaries such as lung, brain, kidney It is swollen, dyshaemia is caused, the generation of other serious conditions is caused.

Studies at home and abroad show that particle pyrogen sample is anti-when ultimate filter of the aperture less than 5 μm can effectively prevent infusion It answers, ultimate filter of the aperture less than 3um can effectively reduce infusion pain, reduce the generation of transfusional phlebitis.So defeated Install the secondary filter film in gradient aperture on liquid device additional, being formed, there is the automatic liquid-stopping transfusion apparatus of multi-layer film structure will filter out particle Aspect plays a significant role, while also should ensure that good only liquid effect；The utility model develops a kind of essence on the basis of this Close filter-type automatic liquid-stopping transfusion apparatus.

Summary of the invention

(1) the technical issues of solving

The utility model provides a kind of secondary filter type automatic liquid-stopping transfusion apparatus, there is automatic liquid-stopping effect, greatly improves defeated The safety in utilization and practicability of liquid device have preferable market prospects, are suitable for promoting.

(2) technical solution used

The utility model to achieve the above object, is achieved by the following technical programs: a kind of secondary filter type is automatic Only liquid infusion apparatus, the infusion apparatus include the bottle plug puncture unit for passing sequentially through perfusion tube connection, dropping funnel, flow regulator, medical fluid Automatic liquid-stopping device, cone joint and intravenous needle are filtered, the lower part of bottle plug puncture unit connects air filter；

The medical filtration automatic liquid-stopping device includes stopping liquid bucket, is equipped with automatic fitration in the only liquid bucket and stops liquid film, institute Stating only liquid bucket is hollow cylindrical structure, and the filtering stops liquid film and is horizontally installed in only liquid bucket；

The filtering auto-stopping liquid film is gradient aperture filter membrane, and the filter membrane is three-decker.

Two layers of aperture is 2 μm on the outside of the filter membrane as a further optimization of the solution, and middle layer aperture is 0.4 μ m。

(3) beneficial effect

The utility model provides a kind of secondary filter type automatic liquid-stopping transfusion apparatus, has the advantages that

The utility model in only liquid bucket by being equipped with three layers of gradient aperture filter membrane, when medical fluid is passing through first layer filter membrane When, filtered larger-size particle (> 2um) first, then in comparatively dense middle layer, particle be further filtered (> 0.4um), finally when passing through filter membrane lower layer, aperture increases enable medical fluid to pass through with high flow velocities;When medical fluid input will tie Shu Shi, the drug drop of filter membrane interlayer structure is under surface tension effects so that filter membrane central part pushes to block infusion Pipe, stop liquid conveying.

The utility model can effectively act as the effect of only liquid film, not influence the stream of infusion apparatus Chinese medicine liquid in infusion process It is dynamic, medical fluid can be terminated after infusion in time, air is avoided and enters vein, considerably increases making for automatic liquid-stopping transfusion apparatus With safety and convenience, make entire infusion process more safety convenient.
