Abstract
The utility model relates to a medical injection and medicine dispensing needle head for preventing rubber stoppers from being polluted, which is characterized in that a needle tip is an enclosed cone, small holes are arranged on the two sides of a needle rod at a position which is near the needle tip, and the small holes are communicated with an inner cavity of the needle rod. The structure can effectively overcome the defect of the prior art that medicine is polluted by the dregs of the rubber stopper of medicine bottles during injection and dispensing medicine. The utility model has the characteristics of novel conception, simple manufacture and time saving and labor saving for operators.
Description
This utility model relates to a kind of medication injections and makes up a prescription with anti-skin plug contaminated pinhead.
For the venous patient drug administration by injection is that each medical institutions uses treatment means always at present, it is an important safety program that injection is made up a prescription.The syringe needle that uses that makes up a prescription before each medical institutions' intravenous injection at present has a sharp oblique section on needle point, when needle point inserted medicine bottle skin plug, skin plug material was easily fallen into the liquid by sharp needle point oblique section ring cutting.Syringe needle is not of uniform size, the skin plug slag of the cutting-out medicine that both polluted not of uniform size, and in case be transfused in the patient body and will form thromboembolism, jeopardize patient's life, the skin plug slag of cutting-out is littler, more easily is transfused in the patient body, dangerous more greatly.
The present utility model purpose is to provide that a kind of manufacturing simple operations is time saving and energy saving can overcome above-mentioned shortcoming, and safe and reliable makes up a prescription with anti-skin plug contaminated pinhead.
The syringe needle that this utility model provides is made up of needle handle 1, shank 2, needle point 3, it is characterized in that needle point is the sealing cone, and has aperture 4,5 at shank near both sides, needle point place, communicates with shank 2 internal cavities.
Below in conjunction with description of drawings this utility model embodiment:
When inserting medicine bottle skin plug under the effect of syringe needle in external force, because of its needle point is the sealing cone, there is not the event of ring cutting power can not produce skin plug slag to medicine bottle skin plug, prevent medicine pollution.The aperture 4,5 that medicinal liquid then can be opened by the shank both sides, shank, needle handle internal cavity free in and out under the syringe pressure effect, finish the process of making up a prescription.
The utlity model has novel, make simply, the characteristics that the operator is time saving and energy saving have solved long-term puzzlement and have joined The skin plug pollutes big problem in the medicine process.
