Description
Technical field
This utility model relates to a kind of single use multifunctional transfusion system, belongs to medical instruments field.
Background technology
Traditional single use precision filter infusion set is when clinical transfusion, medicinal liquid all occurs or produces " air bubble " when entering dropping funnel and enter round filter again, meanwhile, because of pipe inner wall surface tension effects, very easily form absorption pipe inner wall minute bubbles, not easily discharge.Above-mentioned produced air bubble, as entered in patient body, easily causes the harm such as air blocking.On the other hand, existing single use precision filter infusion set does not have the function of automatic liquid-stopping.
Nursing staff is before transfusion, must by the emptying as far as possible of bubble in conduit, the mode of the minute bubbles a brief period of time being adsorbed on pipe inner wall constantly need be played conduit outer wall by artificial discharge bubble process, the minute bubbles of absorption are made to float up in dropping funnel more than liquid level, but be very easily again adsorbed in pipe inner wall in minute bubbles floating-upward process, cause whole artificial discharge bubble process loaded down with trivial details time-consuming, be unfavorable for promptly infusing and giving emergency treatment to a patient, increase work load to medical personnel simultaneously.
Single use precision filter infusion sets all at present, when clinical transfusion, often there will be following situation:
1, dropping funnel ventilation is inverted;
2, with the aerofluxus of finger bomb tube wall;
3, make round filter tilt 45 degree and be full of aerofluxus;
4, medicinal liquid to flow under dropping funnel as infused after pipeline again, at this moment can not second time aerofluxus, again again to patient's puncture, not only can only increase the misery of patient, and again waste medical material;
5, at the end of transfusion nearly, owing to being afraid of that air enters in transfusion catheter, often just pulling out intravenous needle when medicinal liquid is not totally lost, generally can remain a part of medicinal liquid in medicinal liquid bottle, therefore not reach therapeutic effect, cause liquid waste;
6, medicinal liquid stream complete after, sometimes because of nursing forgotten to pull out patient's intravenous needle on hand not in time, cause air to enter in human body, cause blood vessel blood back to bring injury to patient, therefore give nursing staff spirit increase pressure, cause the fear of patient simultaneously.
Therefore, existing transfusion device urgently improves.The purpose of this utility model is the shortcoming overcoming prior art, there is provided a kind of single use multifunctional transfusion system, energy is Exhaust Gas automatically, functions such as " secondary filter, diaphragm stop the aerofluxus again of liquid, diaphragm ", completely solve the various problems that current transfusion device exists, and safe and reliable.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, this utility model will be described in further detail.
As shown in Figure 1 and 2, a kind of single use multifunctional transfusion system, comprise the bottle plug puncture unit 2, dropping funnel 6, filter 11 and the transfusion needle 14 that are communicated with successively by conduit 4, catheter length between described filter 11 and dropping funnel 6 is 250mm, pipeline section on described conduit 4 between transfusion needle 14 and filter 11 is provided with flow regulator 12, described conduit 4 is communicated with the link of dropping funnel 6 liquid outlet main body tube 8 road stretching into dropping funnel 6 inner chamber, described main pipeline 8 upper end is provided with separatory cap 7, and main pipeline 8 circumferential portion is furnished with 2 ~ 6 and is provided with hole, gap vertically; Medicinal liquid flows in dropping funnel 6, be diverted to dropping funnel 6 medial wall by shunting cap 7 and flow to bottom dropping funnel 6, reduce the generation of air bubble, simultaneously, due to the tension force in hole, gap on main pipeline 8, medicinal liquid can not enter in main pipeline 8 at once, but when medicinal liquid is accumulate to close to shunting cap 7, and medicinal liquid just automatically to enter in gap and to flow in main pipeline 8.
In the present embodiment, only liquid film 9 is provided with in described filter 11, when medicinal liquid enters filter 11 from dropping funnel 6, owing to stopping the tension force of pore on liquid film 9, only liquid film 9 can not be penetrated at once, but again accumulate, when amount of liquid medicine is enough, just can penetrate and stop liquid film 9 and infuse through conduit 4 and transfusion needle 14 pairs of human bodies after stopping liquid film 9 and filtering, at the end of transfusion, when medicinal liquid only above liquid film 9 is less than through only liquid film 9 aequum, residue medicinal liquid then isolatedly can realize automatic liquid-stopping above only liquid film 9.
In the present embodiment, described filter 11 is provided with 1 ~ 3 and is positioned at the steam vent 10 stopped above liquid film 9, described steam vent 10 is provided with liquid gas diffusion barrier, the aperture of described steam vent 10 is 0.8 ~ 1.6mm, when medicinal liquid is accumulated in filter 11, the bubble in medicinal liquid then can be discharged from steam vent 10, realizes automatic vent, do not need to be exhausted by diffuse cutting filter 11, easy to use.
In the present embodiment, the length of described main pipeline 8 is 1/2nd of dropping funnel 6 length, and hole, described gap is wide is 0.45 ~ 0.8mm, and on described only liquid film 9, air vent aperture is 2 ~ 5 μm.
In the present embodiment, described bottle plug puncture unit 2 is provided with sheath 1, and described bottle plug puncture unit 2 sidepiece is provided with air filter 3.
In the present embodiment, described conduit 4 is connected with transfusion needle 14 by screwed union 13, and conduit 4 is also provided with threeway injection member 5 with the connecting portion of dropping funnel 6 inlet.
This single use multifunctional transfusion system reduces the generation of air bubble by main pipeline, and realize secondary automatic vent by the steam vent 10 on filter 11, really accomplish in medicinal liquid without " air bubble ", and aerofluxus thoroughly, totally, do not need because of when starting to infuse or change the problem producing " air bubble " when bottle is infused again, make patient very safe in entirety transfusion.And there is automatic liquid-stopping function, avoid human vas blood back to occur " thrombosis ", be conducive to the clinical position of medical personnel, alleviate working strength and the pressure of medical personnel, decrease and to protect between trouble therefore and the medical tangle that causes, and reduce nursing Risk, improve nursing quality.
This single use multifunctional transfusion system operation principle is: when transfusion starts, medicinal liquid flows in dropping funnel 6, dropping funnel 6 internal perisporium is diverted to and bottom following current accumulation and dropping funnel 6 by the shunting cap 7 in dropping funnel 6, this branching process greatly reduces the generation of air bubble, when medicinal liquid to be accumulate in dropping funnel 6 close to shunting cap 7, medicinal liquid pressure itself makes it automatically enter to flow in main pipeline through hole, gap; When this medicinal liquid enters filter 11, medicinal liquid is accumulated again, and is automatically discharged by steam vent 10 filter 11 bubble, and when filter 11 Chinese medicine liquid measure adds up enough, medicinal liquid penetrates to stop liquid film and filter rear inflow catheter and infused to patient through transfusion needle 14; After transfusion terminates, residue medicinal liquid stream is dammed by the tension force stopping liquid film and realizes automatic liquid-stopping, as infused again, plugging another bottle of liquid medicine and can continue transfusion.Therefore, this product has accomplished the three zones of automatic vent, automatic liquid-stopping, secondary filter completely when infusing.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
