Abstract
The utility model provides a self-exhaust type infusion apparatus capable of automatically stopping liquid. The self-exhaust type infusion apparatus comprises a tap funnel, wherein the tap funnel comprises an upper tap funnel and a lower tap funnel; the lower tap funnel comprises an inner base, a drainage tube and an outer base; the lower part of the upper tap funnel is connected to the inner base; a liquid stop film and an exhaust hole are arranged in the inner base; the liquid stop film is made of a hydrophilia material; an exhaust film is made of a lyophobic breathable material. The self-exhaust type infusion apparatus capable of automatically stopping the liquid is simple and ingenious in structure, and is capable of effectively eliminating a bubble phenomenon during infusion, and realizing the self-exhaust and liquid stop functions.
Description
Technical field
This utility model relates to a kind of transfusion device, is specifically related to a kind of from exhaust automatic liquid-stopping transfusion apparatus.
Background technology
At present, when hospital carries out venous transfusion to clinical patients, generally use disposable transfusion device, like this to preventing that the cross infection between patient from having played useful effect.Yet, use this disposable transfusion device also to exist weak point, be that current disposable transfusion device is after medicinal liquid infusion-completed, because there is no automatic-diversion closure function, to change in time medicinal liquid bottle (bag) or pull out transfusion needle, otherwise air will enter transfusion catheter, can bring unsafe factor to patient, be unfavorable for the treatment of clinical patients; In addition, when transfusion device herb liquid starts to enter dropping funnel, very easily form the mixture of gas and liquid, this gas-liquid mixture can enter rapidly in the infusion pipeline of dropping funnel below, bubble phenomenon while forming transfusion, threatens to the healthy of patient, so medical personnel are when transfusion, after bubble in transfusion catheter must being discharged completely, infuse again, to medical personnel, bring great inconvenience.And in recent years also there is the novel transfusion devices of many these difficult problems of solution, if application number is CN201210166988.X, name is called the patent application of full-automatic infusion device, application number is CN 201110343706.4, name is called a kind of automatic vent and the only patent application of the multiple-effect infusion set of liquid, all with hydrophilic film and hydrophobic membrane, bear respectively only liquid and from degassing function, but the bubble phenomenon when avoiding infusing and the structure that designs is all more complicated, thereby there is performance difficulty or the higher problem of production cost of producing.
Summary of the invention
This utility model provides a kind of simple and ingenious structure, the bubble phenomenon in the time of effectively eliminating transfusion, and have concurrently from aerofluxus and stop the transfusion device of liquid function.
This utility model adopts following technical scheme:
A kind of from exhaust automatic liquid-stopping transfusion apparatus, comprise dropping funnel, described dropping funnel comprises dropping funnel 1 and lower dropping funnel, the top of upper dropping funnel 1 communicates with infusion pipeline, described lower dropping funnel comprises interior base 3, drainage tube 4 and outer base 5, base 3 in upper dropping funnel 1 bottom connects, only liquid film 2 is set in interior base 3, described only liquid film 2 outward flanges and the 3 inwall welding of interior base, interior base 3 arranges a steam vent with on wall that only liquid film 2 is connected, exhaust membrane 6 sealings for steam vent, exhaust membrane 6 is welded on interior base 3 outer walls, together with the bottom welding of interior base 3 and outer base 5, drainage tube 4 lower ends are welded on the bottom of interior base 3 and outer base 5 and are connected with infusion pipeline.
Only liquid filter membrane adopts hydrophilic material to make, and exhaust membrane adopts hydrophobic close gas material to make.Interior base 3, outer base 5 and drainage tube 4 all adopt compared with hard plastics, and hardness is at Shao Shi D more than 65.
Described drainage tube upper end is apart from stopping liquid film 0.3mm～0.5mm, and drainage tube internal diameter 1.5mm～2.5mm, can effectively eliminate bubble like this, stops bubble to enter lower end infusion pipeline, and does not affect transfusion speed.In interior base 3, have little time can discharge through exhaust membrane 6 from transfusion needle expellant gas via lower pipeline.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment dropping funnel structural representation.
The specific embodiment
Embodiment
As shown in Figure 1, this utility model is a kind of from exhaust automatic liquid-stopping transfusion apparatus, comprise dropping funnel, described dropping funnel comprises dropping funnel 1 and lower dropping funnel, the top of upper dropping funnel 1 communicates with infusion pipeline, described lower dropping funnel comprises interior base 3, drainage tube 4 and outer base 5, base 3 in upper dropping funnel 1 bottom connects, only liquid film 2 is set in interior base 3, described only liquid film 2 outward flanges and the 3 inwall welding of interior base, interior base 3 arranges a steam vent with on wall that only liquid film 2 is connected, exhaust membrane 6 sealings for steam vent, exhaust membrane 6 is welded on interior base 3 outer walls, together with the bottom welding of interior base 3 and outer base 5, drainage tube 4 lower ends are welded on the bottom of interior base 3 and outer base 5 and are connected with infusion pipeline.
Described only liquid film 2 adopts hydrophilic poly (ether sulfone) film to make, and exhaust membrane 6 adopts hydrophobic close gas material polydimethylsiloxane to make.Interior base 3, outer base 5 and drainage tube 4 all adopt the hard plastics of Shao Shi D 70.
Described drainage tube 4 upper ends are 0.3mm from the distance of stopping liquid film 2, and drainage tube 4 internal diameters are 1.5mm.
After transfusion device is connected with drop bottle, medicinal liquid enters in dropping funnel bottom in base 7, when the moistening of medicinal liquid energy stops liquid film 2, medicinal liquid starts to enter bottom infusion pipeline by drainage tube 4, without being inverted or squeezing dropping funnel, medical personnel get rid of the gas in the infusion pipeline of bottom via transfusion needle after, the gas in interior base 3 can be discharged through exhaust membrane 6.When a bottle liquid medicine infused, medicine liquid level position in dropping funnel arrives only liquid film 2 places, stop under the capillary effect of liquid film, venous pressure in transfusion tube wall and gravitative pressure active force and only liquid film equalization of strain, be under the comprehensive function power of atmospheric pressure, hydrostatic pressing, human vein, medicinal liquid to be rested in transfusion device, reach the function of automatic liquid-stopping
