Abstract
The utility model relates to a liquid dispensing device for medical use, which comprises a flexible needle tube body. The two ends of the flexible needle tube body are respectively provided with a hard needle tube end, wherein one end of the hard needle tube end is connected with a suction tube. The other end of the hard needle tube end is connected with an injection tube. The other end of the suction tube is connected with a suction syringe needle while the other end of the injection tube is connected with an injection syringe needle. The suction tube and the injection tube are respectively provided with a check valve. In a liquid dispensing process, the suction syringe needle is first inserted into a liquid medicine bottle while the injection syringe needle is inserted into an infusion bottle. Then the flexible needle tube body is pressed. The liquid medicine is sucked from the suction tube into the flexible needle tube body under the influence of check valve. Again the flexible needle tube body is pressed. The liquid medicine sucked into the flexible needle tube body first passes through a filtering membrane and then is injected from the injection tube into the infusion bottle. The liquid medicine is free of pollution during the whole liquid dispensing process. Meanwhile, the liquid medicine injected into the infusion bottle will contain no impurities due to the filtering membrane for filtration. Furthermore, the utility model which is simple in operation, labor-saving and time-saving reduces the labor input of the nursing personnel.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that uses in hospital, relates to a kind of dispenser of using in hospital specifically.
Background technology
Transfusion is clinical 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, and infusion model has experienced full open model transfusion, semi open model transfusion and 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 the interior medicinal liquid of air-tight bottle usually clinically at present, is injected into then in the infusion bottle to prepare needed various liquid.
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, in extraction process, medicinal liquid is contaminated easily, the right hand that the operator holds 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 operation very bothers, wastes time and energy, and has increased workload to the nursing staff.
The utility model content
Problem to be solved in the utility model is at above problem, provides a kind of dosing process herb liquid to be difficult for contaminated, easy to operate medical liquid dispenser.
For addressing the above problem, the technical scheme that this utility model adopted is: a kind of medical liquid dispenser, comprise soft needle tube body, the two ends of described soft needle tube body are respectively arranged with rigid needle tubing end, wherein the rigid needle tubing end of an end is connected with suction tube, and the rigid needle tubing end of the other end is connected with ascending pipe, and the other end of described suction tube is connected with the suction syringe needle, the other end of described ascending pipe is connected with the injection syringe needle, is respectively arranged with check valve on described suction tube and the ascending pipe.
A kind of concrete prioritization scheme is provided with filter membrane in the rigid needle tubing end that is connected with ascending pipe.
This utility model is taked above technical scheme, have the following advantages: in the dosing process, to aspirate syringe needle inserts in the medicinal liquid bottle, to inject syringe needle and insert infusion bottle, push soft needle tube body, under the effect of check valve, medicinal liquid is inhaled in the soft needle tube body from suction tube, and then push soft needle tube body, suck the intravital medicinal liquid of soft needle tubing through behind the filter membrane, inject infusion bottle from ascending pipe, in the whole process of making up a prescription, medicinal liquid can be not contaminated, behind the membrane filtration, the medicinal liquid that injects infusion bottle can not contain impurity after filtration, and operation is very simple, time saving and energy saving, reduced nursing staff's workload.
The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing is the structural representation of a kind of medical liquid dispenser among this utility model embodiment.
Among the figure:
1-aspirates syringe needle; The 2-needle stand; The 3-suction tube; The 4-check valve; The rigid needle tubing end of 5-; The soft needle tube body of 6-; The 7-filter membrane; The 8-check valve; The 9-ascending pipe; 10-injects syringe needle.
The specific embodiment
Embodiment: as shown in drawings, a kind of medical liquid dispenser, comprise soft needle tube body 6, the two ends of soft needle tube body 6 are respectively arranged with rigid needle tubing end 5, and wherein the rigid needle tubing end 5 of an end is connected with suction tube 3, and the rigid needle tubing end 5 of the other end is connected with ascending pipe 9, the other end of suction tube 3 is connected with suction syringe needle 1, the other end of ascending pipe 9 is connected with and injects syringe needle 10, and suction tube 3 is provided with check valve 4, and ascending pipe 9 is provided with check valve 8.
Be provided with filter membrane 7 in the rigid needle tubing end 5 that is connected with ascending pipe 9.
Be provided with needle stand 2 between suction syringe needle 1 and the suction tube 3, be provided with needle stand 2 between injection syringe needle 10 and the ascending pipe 9.
In the dosing process, to aspirate syringe needle 1 and insert in the medicinal liquid bottle, will inject syringe needle 10 and insert infusion bottle, push soft needle tube body 6, check valve 4 is closed, check valve 8 is opened, and the gas in the soft needle tube body 6 is discharged, and unclamps soft needle tube body 6, check valve 4 is opened, check valve 8 is closed, and medicinal liquid is inhaled in the soft needle tube body 6 from suction tube 3, and then pushes soft needle tube body 6, check valve 4 is closed, check valve 8 is opened, and sucks medicinal liquids in the soft needle tube body 6 through behind the filter membrane 7, injects infusion bottles from ascending pipe 9, in the whole process of making up a prescription, medicinal liquid can be not contaminated, and after filtering through filter membrane 7, the medicinal liquid that injects infusion bottle can not contain impurity.
