Description
Technical field
This utility model relates to the auxiliary equipment field of medical intravenous infusion device, particularly relates to a kind of efficient air purifier of infusion set.
Background technology
The air purifier transfusion apparatus that each hospital of current China uses is all have an air inlet communicated with air, the harmful substances such as the nitric oxide in air, sulfur dioxide, nitrogen dioxide, floating dust, organic pollution and plumbous inorganic compound, enter transfusion by air inlet directly to input in patient blood, serious harm can be brought to patient health.General air purifier transfusion apparatus have employed active carbon and adsorbs the harmful substance in air, although the activated carbon industrial waste gas higher to the waste gas degree of depth has good adsorption.But result of the test shows, activated carbon is to non-industrial waste gas, and in gas as lower in exhaust gas concentrations such as general atmospheres, the adsorptive value of nitrogen oxide is lower.And activated carbon is comparatively soft, wears no resistance, frangible powdered, if the air filtration being applied to transfusion device, is then unfavorable for clear production, is also easily in use brought in medicinal liquid by the powder of activated carbon.
Therefore, those skilled in the art, through research and development, develops the air purifier for intravenous drip that the patent No. is 96118336.5, and it uses molecular sieve, impregnated carbon and microporous filter membrane purification floating dust; Sulfur dioxide is removed with the solid absorption pipe (glass dust adsorption tube) that carbonate and living solution (being made up of one or several in glycerol, propylene glycol, triethanolamine) flood; After flooding triethanolamine, sodium chloride, sulfamic acid solution by solid absorption pipe (one or more compositions containing in activated carbon, Linesless charcoal, silica gel, molecular sieve, activated alumina, porous ceramics), through conventional vacuum filtration and cold drying, for removing nitrogen oxide.
But, it also has following shortcoming: 1, the air drag of the microporous filter membrane of energy filtering microorganism is larger, can not natural filtration under normal pressure, need additional certain pressure, namely the requirement in 6.5 clauses in GB8368-2005 " disposable infusion, blood transfusion, instrument used for injection standard " can not be reached: " by when A.4 chapter is tested, should not 20% be reduced relative to the flow of trickle in the container from free air inlet." 2, remove the solid absorption pipe of sulfur dioxide; due to containing one or several liquid in middle glycerol, propylene glycol, triethanolamine; when air flows through this adsorption tube; air also carries the gaseous material of these liquid; and can not by filtering with microporous membrane; and then enter into the medicinal liquid of transfusion device, cause secondary pollution even toxic reaction.3, after the solid absorption pipe (one or more compositions containing in activated carbon, Linesless charcoal, silica gel, molecular sieve, activated alumina, porous ceramics) for removing nitrogen oxide floods triethanolamine, sodium chloride, sulfamic acid solution, " through conventional vacuum filtration and cold drying; " this preparation method, because triethanolamine is easy to and carbon dioxide reaction, and have a large amount of carbon dioxide in air, thus the triethanolamine being used in removing nitrogen oxide loses activity; And sulfamic acid belongs to the sour corrosion product in hazardous chemical, be not suitable for directly entering in the transfusion device of blood of human body; It is dry through conventional vacuum filtration and cold drying after sodium chloride, sulfamic acid dissolve, can form loose powder is attached on adsorbate, in processing with transportation, powder can come off, be not suitable for this kind of medical apparatus and instruments of transfusion device to produce by GMP in clean room, and dust is in air filter, as the air flows past, the dust still having certain proportion chemical substance enters into medicinal liquid, pollutes even toxic reaction.
