[detailed description of the invention]
Consult Fig. 1, this utility model, comprise bottle plug puncture unit 1, first transfusion catheter 2, Murphy's dropper 3, liquid medicine filter 6 and venoclysis needle 9, described bottle plug puncture unit 1 connects the first transfusion catheter 2, Murphy's dropper 3, second transfusion catheter 4, liquid medicine filter 6, end tube for transfusion 8, venoclysis needle 9 successively, and described liquid medicine filter 6 is connected with end tube for transfusion 8 by connector 7; Described first transfusion catheter 2 is provided with filling opening 21, and the second transfusion catheter 4 is provided with actuator 5.
Consult Fig. 2, be provided with exhaust apparatus in described Murphy's dropper 3, exhaust apparatus comprises hydrophobic exhaust membrane 33, exhaustor 34, steam vent 36, and described Murphy's dropper 3 upper end is provided with hydrophobic exhaust membrane 33, and hydrophobic exhaust membrane 33 outside is provided with aerofluxus containment vessel 31; Described Murphy's dropper 3 inside is provided with exhaustor 34, and exhaustor 34 is provided with several steam vents 36; Described exhaustor 34 is connected with the second transfusion catheter 4, and exhaustor 34 bottom is provided with intake chute 35, and intake chute 35 is connected with the second transfusion catheter 4.Described exhaustor 34 top is provided with several steam vents 36, and the height of exhaustor 34 is higher than 1/2nd of Murphy's dropper 3 height.Described aerofluxus containment vessel 31 is arranged on Murphy's dropper 3 outer wall, aerofluxus containment vessel 31 has passage 32.
Consult Fig. 3, in described liquid medicine filter 6, be provided with the unidirectional blood return prevention valve 62 of the first unidirectional blood return prevention valve 61, second.Described first unidirectional blood return prevention valve 61 and the outer convex of the second unidirectional blood return prevention valve 62 are arranged, and the first unidirectional blood return prevention valve 61 and the second unidirectional blood return prevention valve 62 are positioned at the both sides of liquid medicine filter 6 import.Liquid medicine filtering membrane 63 is provided with in described liquid medicine filter 6.
Utility model works process:
A kind of transfusion device of this utility model in the course of the work, bottle plug puncture unit 1 penetrates in medicine bottle, medicinal liquid flows through bottle plug puncture unit 1, first transfusion catheter 2, Murphy's dropper 3, second transfusion catheter 4, liquid medicine filter 6, end tube for transfusion 8, venoclysis needle 9 successively, because exhaustor 34 seals the outlet of Murphy's dropper 3, medicinal liquid only may flow down from the intake chute 35 exhaustor 34, when liquid level be elevated to seal steam vent 36 topmost time, intracavity gas is compressed, form malleation, medicinal liquid is first pressed into from steam vent 36 upper end.When under medicinal liquid oozes, impact the medicinal liquid of Murphy's dropper 3 lower end, may sandwich bubble, steam vent 36 can also stop this impact bubble.
Do not need to be inverted or extruding Murphy's dropper 3; do not need to close flow regulator 5 yet; due to surface tension and the capillarity of liquids and gases; first aerofluxus body; surface tension liquid enters exhaustor 34 hollow inside through intake chute 35 is broken through when liquid level continues to rise and covers steam vent 36; air in Murphy's dropper 3 can be discharged by the hydrophobic exhaust membrane 33 of Murphy's dropper 3 upper end; aerofluxus containment vessel 31 plays the effect protecting hydrophobic exhaust membrane 33, also can ensure the health of hydrophobic exhaust membrane 33.
Liquid flows through liquid medicine filter 6 by the infusion pipeline below Murphy's dropper 3, be provided with in liquid medicine filter 6 first unidirectional blood return prevention valve 61 and the second unidirectional blood return prevention valve 62, when medicinal liquid normal stream is out-of-date, the compression shock blood return prevention valve of medicinal liquid, medicinal liquid by the first unidirectional blood return prevention valve 61 and the second unidirectional blood return prevention valve 62 intermediate flow to liquid medicine filtering membrane 63; When liquid reverse flow appears in blood back situation, the resilient support of the first unidirectional blood return prevention valve 61 and the second unidirectional blood return prevention valve 62 gets back to original position, blocks the infusion channel of liquid medicine filter 6, and infusion channel blocks, and just achieves the one-way flow of liquid.Medicinal liquid is infused in patient body eventually through venoclysis needle 9.
The state of blood back arrives in end tube for transfusion 8, and the more existing contraction in length of length of end tube for transfusion 8, also shortens maximum blood back length, avoid the injury to patient body.
This utility model structure is simple, can automatic vent in infusion process, prevents bubble to bring in transfusion catheter, safe and convenient to use, add blood return prevention valve in liquid medicine filter 6, realize the one-way flow of medicinal liquid, very not large to the structural modification of existing transfusion device, easy to process, popularization degree is high.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after this utility model simple transformation.
