ICU Medical, Inc. discloses the technical scheme of malleation flow valve of the same race in CN97181779.0 and CN200410076931.6 and CN200610100685.2, it is characterized in that: can accept in the inner chamber of the opening of ansi standard joint at one, if an elastic packing silica gel plug and with opening close fit, there is gap the centre of plug, can open under external force pressure, fluid in ANSI joint is made to enter in the liquid chambers in inner chamber, this chamber is easily extensible under external force pressure, after external force is removed, collapsible by liquid heats to drain pipe direction, avoid blood backflow formed bolt block up.
Above technical scheme is all the malleation implementation connected based on needleless, and its common deficiency is exactly the danger that there is microorganism intrusion, also has baroque factor simultaneously.
The present invention proposes a kind of scheme avoiding above-mentioned deficiency newly, not only can realize malleation, but also the danger of microorganism intrusion can be exempted, also there is simple, the easy to operate feature of structure simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of liquid infusion pipe capsule valve with two compression functions newly.
The present invention is made up of pipe capsule and clamp, it is characterized in that: clamp is arranged on the pipe capsule in indwelling pipeline, infused and pull out with the connection of indwelling part after, by the bending of pipe capsule and jam on clamp, make the U-shaped closed condition of pipe capsule, now, the liquid in sacculus will flow to orientation treatment and form malleation; When reusing, only pipe capsule need be pulled out from clamp, pipe capsule will progressively recover in a straight line and make the unimpeded of infusion pipeline under the effect of natural resiliency, and increase is formed negative pressure by the space now in pipe capsule, under the effect of this negative pressure, blood will reflux.
During the bending of pipe capsule produce malleation flow and be greater than negative pressure amount when indwelling pipeline and infusion pipeline are removed; The negative pressure flow that the bending of pipe capsule produces when being opened is greater than the pipeline inner chamber capacity of the intervention human body skin on indwelling pipeline.
The curved capsule dual-pressure valve of above-mentioned one, will not change clinical manipulation code and have following advantage in infusion process:
● clear in structure, simple structure, the basis of traditional remaining needle pipeline only increases positive pressure tube sealing and negative pressure authentication function that an elastic tube capsule just achieves remaining needle.
● simple to operate, only the bending of pipe capsule just need can be completed on clamp the work expection of positive pressure tube sealing after having infused; When again infusing, only need the pipe capsule of bending to pull out from clamp.
