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 filtering automatic liquid-stopping transfusion apparatus.
Summary of the invention
(1) the technical issues of solving
The utility model provides a kind of secondary filter automatic liquid-stopping transfusion apparatus, has 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 auto-stopping
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 mistake
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 left circular cover and right circular cover, the left circular cover and the right side
Cylinder shape groove, the cylinder shape groove mutual cooperation shape on the left circular cover and right circular cover are equipped on circular cover
At cylindrical cavity；The cylindrical empty is intracavitary to stop liquid filter membrane equipped with filtering, and the Filtration Filtration stops liquid film for cylindrical cavity
It is divided into the first cavity and the second cavity, inlet tube is connected on first cavity, connects outlet tube on second cavity；
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 automatic liquid-stopping transfusion apparatus, has the advantages that
The utility model is by being equipped with three layers of gradient aperture filter membrane cylindrical empty is intracavitary, when medical fluid is passing through first layer
When filter membrane, larger-size particle (> 2um) has been filtered first, then in comparatively dense middle layer, particle is 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
At the end of, the drug drop of filter membrane interlayer structure is under surface tension effects so that filter membrane central part pushes to block out
Liquid 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.
