Description

Disposable liquid dispenser

Technical field:

This utility model relates to medicine technology field, is the liquid dispensing device that a kind of patient of being used to carries out infusion treatment, specifically, is a kind of disposable liquid dispenser.

Background technology:

Transfusion is interim the most frequently used important treatment means, and it is to import the Therapeutic Method that various infusion solutions are means with vein, also is referred to as liquid undergoing treatment.It starts from 1831, existing so far 171 years history.During this time, infusion model has experienced full open model transfusion, semi open model transfusion, all-sealed transfusion.The transfusion purpose is divided into: keep transfusion, additional transfusion, carrier transfusion.No matter which kind of infusion model and transfusion purpose, obtaining liq is indispensable link.Obtaining liq adopts asepsis injector to extract in the ampoule or the air-tight bottle inner liquid medicine is injected into the needed various liquid of preparation in the infusion bottle usually clinically at present.

Usually select 20ml syringe obtaining liq clinically for use.5ml, the molten amount of 10ml syringe are little; 50ml syringe volume is big, equal inconvenient dosing operation.When the amount of liquid medicine of the required extraction of obtaining liq is big, syringe will extract for several times repeatedly, when extracting medicinal liquid, the right hand that requires the operator to hold syringe can only pull back the extraction medicinal liquid with the axis of the piston of the third finger or little finger of toe latch closure syringe, and piston must not be touched in any position of hands.Workload is big when infusing, and the especially work of transfusion room is difficult to accomplish from start to finish this point.In case touch piston, extract more than the medicinal liquid frequency secondary, liquid just might be contaminated.When needing dissolving medicine powder obtaining liq, use one pair of syringe, two needle points usually.Extract liquid in the infusion bottle earlier, dissolved substance, extract medicinal liquid again and inject infusion bottle, in the whole operation process, the needle point syringe nipple connects separation repeatedly, guarantee that operator's left hand thumb, forefinger only touch the pintle outer wall, this just needs the nurse that the working sense of responsibility of firm aseptic operation idea and height is arranged, otherwise does not reach the aseptic operation requirement.When need extracting in the air-tight bottle medicine dosing, because sealing bottle cork is that elastomeric material is made, the repeated localised puncture of needle point has bottle stopper rubber scurf accidentally and sneaks in the medicinal liquid.When patient finds in the liquid particulate matter to be arranged, can suspect it is impurity, mycete or the like.In addition, this particulate matter can cause a series of harm if enter human body, and for example, little blood vessel blockage produces granuloma or the like.The solution of taking at present is: in strict accordance with aseptic technique art rule of operation standard nursing staff transfusion operation, running check transfusion operation quality etc.But transfusion operation can occur in any time, can not all have at any time management personnel inspection, supervise, especially in, night the nurse independent when on duty, depend on nurse's the professionalism and the spirit of being careful of oneself when alone to a great extent.Behind the obtaining liq, whether check in the liquid rubber particle repeatedly.The disposable transfusion device that uses has defecator at present, macroscopic rubber particle can not enter in the human body, but patient still has doubt, so the way of Xie Jueing is prepared again for changing liquid clinically, particularly valuable drug causes bigger waste, sometimes also increased and protected trouble contradiction, increased the outpatients mental state burden.

Summary of the invention:

The purpose of this utility model provides a kind ofly can reduce the link that can pollute in the operation, reduce the foreign body in the medicine that extracts, the waste that reduces medicine, disposable liquid dispenser easy for operation.

Technical solution of the present utility model is: a kind of disposable liquid dispenser, needle tubing is arranged, and it is characterized in that: the two ends of needle tubing are equipped with the suction syringe needle respectively and are injected syringe needle, and at least a portion of needle tubing is soft body.

The two ends of the needle tubing described in this utility model are rigid body, and there have syringe needle that breast is installed at rigid needle tubing end to be protruding, are soft needle tube body at the rigid go-and-retum of needle tubing.In the needle tubing end inboard that the injection syringe needle is housed filter membrane is housed.

The beneficial effects of the utility model are: novel structure, design be ingenious, make things convenient for dosing operation, can reduce the probability that pollutes in the operation, stops the foreign body that medicine produces in aspiration procedure, and can reduce the waste of medicine, and be easy for operation.

Description of drawings:

Below in conjunction with drawings and Examples this utility model is further described:

Accompanying drawing is the structural representation of a kind of disposable liquid dispenser of the present utility model.

The specific embodiment:

Accompanying drawing has been described an embodiment of the present utility model.In this embodiment, needle tubing is arranged, the two ends of needle tubing are equipped with suction syringe needle 1 respectively and are injected syringe needle 2, and at least a portion of needle tubing is soft body 3 (can be made by soft plastic).The two ends of described needle tubing are rigid body 4,5 (can be made by hard plastic), and there have syringe needle that breast is installed at rigid needle tubing end 4,5 to be protruding 6,7, is soft needle tube body 3 at 4,5 at the rigid two ends of needle tubing.In needle tubing end 5 inboards that injection syringe needle 2 is housed filter membrane 8 is housed.On suction syringe needle 1 and injection syringe needle 2, all be set with needle point medicated cap 9,10.Injecting syringe needle 2 is the side opening pin.
