Description

A kind of blood return preventing infusion device exhaust apparatus
Technical field
Patent of the present invention relates to the exhaust apparatus of disposable transfusion device, relates in particular to the exhaust apparatus of Dispensable blood return-preventing transfusion device.
Background technology
Present blood return preventing infusion device does not have exhaust apparatus, and it in use need manually be drained unnecessary air in blood return prevention dropper or the Mo Feishi pipe, and generally finish the deflated time of extruding and need obviously reduce work efficiency more than 20 seconds.
Summary of the invention
Technical problem to be solved by this invention provides a kind of blood return preventing infusion device exhaust apparatus, and blood return preventing infusion device bleeding simplification, evacuation time are shortened.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of blood return preventing infusion device exhaust apparatus, comprise pedestal, filter membrane, sealing-plug, the head end of described pedestal is connected with blood return prevention dropper or Mo Feishi pipe, the tail end of described pedestal is connected with described sealing-plug, and described filter membrane is fixed in the described pedestal.
As preferably, be provided with first hollowed-out board or net, second hollowed-out board or net in the described pedestal, described filter membrane is located between described first hollowed-out board or net, second hollowed-out board or the net.
As preferably, the head end of described pedestal is connected with blood return prevention dropper or Mo Feishi pipe by hollow pipe.
As preferably, described filter membrane is filter membrane ventilative, waterproof formula.
As preferably, described filter membrane is filter membrane ventilative, dankness type.
As preferably, be provided with first hollowed-out board or net, second hollowed-out board or net and the 3rd hollowed-out board or net in the described pedestal successively, described filter membrane is located between described first hollowed-out board or net, second hollowed-out board or the net, be provided with floating plug between described second hollowed-out board or net, the 3rd hollowed-out board or the net, the medial surface on described pedestal top of part between second hollowed-out board or net and the 3rd hollowed-out board or net and shape, the size of floating plug upper outside face are complementary.
As preferably, the head end of described pedestal is connected with described hollow pipe by breather and/or hollow needle.
As preferably, described hollow pipe is the connection tube that extends to form on the perisporium of described blood return prevention dropper or Mo Feishi pipe.
