Description
Technical field
The invention discloses a kind of transfusion device, be specially a kind of disposable use air separation, automatic liquid-stopping anti-empty transfusion system, belong to technical field of medical instruments.
Background technology
Disposable transfusion device is a kind of common disposable medical treatment consumptive materials process aseptic process, that set up passage between vein and medicinal liquid that is mainly used in venous transfusion.Generally by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, a kettle, bottle plug puncture unit, air inlet pipe air filter, connected to form.Its operation principle is under atmospheric pressure effect, and in bottle, the thinner infusion tube of liquid runs down flows into dropping funnel, and when dropping funnel water column pressure is greater than venous pressure, the liquid runs down flexible pipe in bottle flows into vein.
There is following defect in existing disposable transfusion device:
1, before use, needing to push dropping funnel makes medicinal liquid enter dropping funnel;
2, liquid level in uncontrollable dropping funnel, does not control the flow of infusing;
While 3, infusing, have bubble to enter into the liquid, bubble enters human body with medicinal liquid and easily causes aeroembolism.
4, only liquid film adopts fibrous membrane, easily comes off and adsorbs medicine liquid ingredient.
5, can be residual as various particulate matters such as dust, plastic grain, chips of glass, active carbons in medicinal liquid.These microgranules can cause phlebitis, blood vessel embolism, granuloma and other infusion reactions etc.
Therefore, design that a kind of secondary filter microgranule, air are separated, automatic liquid-stopping anti-empty transfusion system is association area technical problem urgently to be resolved hurrily.
Summary of the invention
The object of the invention is for a kind of disposable use air separation, automatic liquid-stopping anti-empty transfusion system are provided,, to solve the problems referred to above of prior art.
Object of the present invention can be achieved through the following technical solutions.

Another kind of transfusion device, is connected to form by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, a kettle, bottle plug puncture unit and air inlet pipe air filter; The end opening of described kettle is provided with the dropping funnel of coupling, and the described kettle that drips arranges " Y " type upper conduit that connects infusion tube; The block water air filter of described " Y " type upper conduit arm for being communicated with outside air; Described dropping funnel consists of connecting portion and dropping funnel portion, and described connecting portion is and drips a kettle and mate and be socketed and bind, and described dropping funnel portion is infundibulate, and a circle step is set in the junction of dropping funnel portion and connecting portion, on the inwall of dropping funnel, be provided be no less than three protruding stupefied; Described is protruding stupefied concordant with step upper surface, and at step and the protruding only liquid film that is welded with on stupefied; On the axis of dropping funnel, be provided with an aerofluxus post; Described only liquid film be multilamellar aperture different poly (ether sulfone) film be formed by stacking.
Described only liquid film is 3-5 layer, and the aperture of every layer is below 15um.Because aperture is different, can there is to the impurity in medicinal liquid good filter effect, size particles can be stoped respectively in different aspects or the position of different pore size, can improve the percent of pass of medicinal liquid.Only liquid film after soaking has the effect that air is cut apart, and next bottle liquid medicine does not have air.
Described welding manner is thermal weld, ultrasonic, high frequency heat seal.
The part of described aerofluxus post in dropping funnel is feed liquor post, and the part outside dropping funnel is the downcomer being connected with infusion tube; On the sidewall of described feed liquor post, be provided with and be no less than two vertical long and narrow lead channel.The width of lead channel is more than 35 decimillimeters.Described place, downcomer oral area inside edge is chamfering.Transfusion catheter is that interpolation type connects.
On described step, be provided with a circle boss, to facilitate bonding air-filtering membrane.The height of described boss is greater than 1mm.
On the described pot lid that drips kettle assembly or sidewall, be provided with the air filter that blocks water being in communication with the outside, the air filter that blocks water is supporting seal cover.The part in dripping kettle of air filter of blocking water is column air vent.
Described dripping on kettle pot lid is also provided with chemical feed pipe, to facilitate dosing when the dropping liquid.
The dropper mouth of described upper conduit and the distance of air vent are more than 1cm, so that observe.
The disposable transfusion device designing by the present invention, with dripping kettle assembly, has following beneficial effect:
1, without extruding dropping funnel, liquid rapid and natural flows into dropping funnel;
2, air vent can be controlled the height of liquid level in dropping funnel, can effectively control infusion flow:
3, the effective bubble in drain of aerofluxus post, has prevented that bubble from entering human body.
4, adopt the compound only liquid film of polyether sulfone, film material does not come off, adsorptivity little (≤3%), is 1/10 of general fibre film, can reduce hardly the effective ingredient of medicine.
5, the microparticle residue in effective filtering liquid medicine, micro particle filtering, except rate reaches more than 95%, has effectively prevented phlebitis, blood vessel embolism, granuloma and other infusion reactions etc. that because of microgranule, cause.
