Abstract
The utility model provides a multi -functional filter of venous transfusion, include: casing, exhaust apparatus, filtration membrane, filtration transfusion system membrane, multi -functional filter of venous transfusion is with self -bleeding, filtration and automatic liquid -stopping and effectual the combining together of four functions of secondary filter, and not only manufacturing cost is lower, at safe and reliable clinically to the infusion velocity of flow satisfies the clinical use requirement.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of venous transfusion multi-functional filter。
Background technology
That commonly uses in the market has automatic liquid-stopping, including notification number from the infusion apparatus product of aerofluxus and secondary filter is that CN102512723B is from aerofluxus bubble-proof transfusion device, it mostly is and on use dropping funnel, increases automatic exhauster and additionally increase accurate filter and from stopping liquid device parts, to reach overall automatic vent, the purpose of automatic liquid-stopping and secondary filter, or will have automatic vent, three kinds of parts of automatic liquid-stopping and secondary filter effect are assembled on transfusion device pipeline successively and use, such transfusion device production cost is higher, production efficiency is low and reduces infusion flow rate, it is unfavorable for Clinical practice。Needs due to infusion safety, current Clinical practice requires that best medical filtration uses the aperture of membrane technology below 5 μm, transfusion device has automatic liquid-stopping and automatic vent and airfiltering safe infusion function has irreplaceable status clinically, market demand has automatic vent, automatic liquid-stopping and a secondary filter etc., less costly, meet the venous transfusion multi-functional filter of Clinical practice requirement。
Summary of the invention
This utility model provides a kind of venous transfusion multi-functional filter, automatic vent, air filtration and automatic liquid-stopping and secondary filter four function are effectively combined together by described venous transfusion multi-functional filter, not only production cost is relatively low, safe and reliable clinically, and infusion flow rate meets Clinical practice requirement。
Venous transfusion multi-functional filter described in the utility model, including: housing, exhaust apparatus, air-filtering membrane, excessively filter infusion apparatus film；Described exhaust apparatus is arranged in housing, exhaust apparatus includes exhaust seat, aerofluxus core and block, the bottom of exhaust seat is fixed on the liquid droping port place of housing bottom and closely cooperates with liquid droping port, the aerofluxus core of the hollow communicated with liquid droping port it is provided with in exhaust seat, being provided with feed liquor gap between aerofluxus core and exhaust seat, aerofluxus core and the sidewall of exhaust seat are provided with lead channel, the top of exhaust seat arranges block, block and exhaust seat fasten, and the sidewall of block is provided with at least one air discharge duct；Described shell top wall is provided with steam vent, steam vent is fixed being coated with air-filtering membrane；Described cross the top that filter infusion apparatus film is fixedly installed in housing exhaust apparatus。
Described housing is to be assembled by upper shell and lower house are fixing。
On described housing, the upper position of air-filtering membrane is movably set with air filtration end cap。
Described filter infusion apparatus film of crossing is poly (ether sulfone) film。
When venous transfusion multi-functional filter device described in the utility model uses on transfusion device, before medicinal liquid is flowed into the housing of venous transfusion multi-functional filter device described in the utility model, air filtration end cap is opened, medicinal liquid reaches the effect of secondary filter through poly (ether sulfone) film, medicinal liquid bubble in the many medicinal liquids of exhaust apparatus carries out double filtration, effectively prevents liquid bubble from flowing into following pipeline；When medicinal liquid infusion to complete, housing upper medicinal liquid no longer drips, cross filter infusion apparatus film surface and form medicinal liquid film, surface tension effects due to medicinal liquid film, cross and in the housing of filter infusion apparatus film bottom, form negative pressure, medicinal liquid cannot continue with human body and in time, automatic stopping infusion, thus preventing air from entering patient's vein, complete venous transfusion multi-functional filter automatic vent described in the utility model, the effect that air filtration and automatic liquid-stopping and secondary filter function effectively combine together, ensure that the safety of transfusion overall process, alleviate the pressure of patient and medical worker；And the problem that venous transfusion multi-functional filter described in the utility model affects infusion flow rate when solving loaded down with trivial details, many assembling parts technique and the use that automatic liquid-stopping and automatic vent and precise filtering device in the market bring, production cost is relatively low, and infusion flow rate is fully able to and meets Clinical practice requirement。
Venous transfusion multi-functional filter device described in the utility model is by the technological improvement in single use automatic vent conventional on market, automatic liquid-stopping, precision filter infusion set technical foundation, make product laminating clinic, reach technology requirement described in the utility model。
