Abstract
A kind of injection or needle for dispensing medicines, comprise needle holder and with the syringe needle tube of closed cutting tip, syringe needle tube is connected with needle holder, the closed cutting tip of described syringe needle tube is tapered setting, the side of tapered closed cutting tip is provided with inclined plane, the gradient on inclined plane is less than the tapering of tapered closed cutting tip, and inclined plane is provided with inlet opening.This utility model is by establishing tapered closed cutting tip, bottle closure of rubber easily punctures, in the side of tapered closed cutting tip, establish inclined plane and inlet opening, new otch can not caused in inclined plane, there is not exfoliation, thereby do not have exfoliation and fall into syringe needle tube internal contamination medicinal liquid, and this inclined plane can be used as while making up a prescription aspiration medicinal liquid medicinal liquid at the bottom of bottle and enter the guide surface in inlet opening, can not cause liquor residue.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of injection or needle for dispensing medicines.
Background technology
Large specification injection or the needle for dispensing medicines of existing clinical use are straight hole pin, when preparating liquid, during the bottle closure of rubber of needle point puncture infusion bottle and sealing phial etc., easily there is puncture exfoliation in straight hole pin, once exfoliation is fallen in infusion bottle or phial, can pollute medicinal liquid; And the side-hole needle of using while making up a prescription is when aspiration medicinal liquid, easily cause liquor residue, waste medicinal liquid.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, and has straight hole medicine administered by injection liquid noresidue and side opening puncture not injection or the needle for dispensing medicines of exfoliation feature.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is a kind of injection or needle for dispensing medicines, be characterized in, comprise needle holder and with the syringe needle tube of closed cutting tip, syringe needle tube is connected with needle holder, and the closed cutting tip of described syringe needle tube is tapered setting, and the side of tapered closed cutting tip is provided with inclined plane, the gradient on inclined plane is less than the tapering of tapered closed cutting tip, and inclined plane is provided with inlet opening.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the gradient of described inlet opening apertura lateralis face equates with the gradient on inclined plane.
This utility model by establishing tapered closed cutting tip on syringe needle tube, bottle closure of rubber easily punctures, in the side of tapered closed cutting tip, establish inclined plane and inlet opening, new otch can not caused in inclined plane, only can be in the incision that starts to obtain, otch support is large, there is not exfoliation, thereby do not have exfoliation, do not fall into syringe needle tube internal contamination medicinal liquid, and this inclined plane can be used as while making up a prescription aspiration medicinal liquid medicinal liquid at the bottom of bottle and enters the guide surface in inlet opening, can not cause liquor residue; Meanwhile, the pore size of inlet opening and the tapering of tapered cutting tip arrange according to transfusion situation.Compared with prior art, it is reasonable in design, easy to use, and while having aspiration medicinal liquid, noresidue and side opening puncture exfoliation do not pollute the function of medicinal liquid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of closed cutting tip.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
See figures.1.and.2, a kind of injection or needle for dispensing medicines, comprise needle holder 1 and with the syringe needle tube 2 of closed cutting tip 3, syringe needle tube 2 is connected with needle holder 1, the closed cutting tip 3 of described syringe needle tube 2 is tapered setting, the side of tapered closed cutting tip 3 is provided with inclined plane 4, and the gradient on inclined plane 4 is less than the tapering of tapered closed cutting tip 2, and inclined plane 4 is provided with inlet opening 5.
The gradient of described inlet opening 5 apertura lateralis faces equates with the gradient on inclined plane 4.
Tapered closed cutting tip 3 is set, when puncture bottle closure of rubber, does not have exfoliation and enter in syringe needle tube 2; In a side of tapered closed cutting tip 3, establish the inclined plane 4 that gradient is less than tapered closed cutting tip 3 taperings, inclined plane 4 is near needle point, inclined plane 4 Passivation Treatment, through after bottle stopper, there is not otch like this, can only support large, there is no sharp otch, just can not produce exfoliation, avoided the pollution to the medicinal liquid in syringe needle tube 2; On inclined plane 4, establish inlet opening 5, the outer hole plane inclination of inlet opening 5 equates with inclined plane 4 gradients, and while extracting medicinal liquid, bottle end medicinal liquid enters in syringe needle tube 2 by the guiding on inclined plane 4.
Claims (2)
1. inject or needle for dispensing medicines for one kind, it is characterized in that: comprise needle holder and with the syringe needle tube of closed cutting tip, syringe needle tube is connected with needle holder, the closed cutting tip of described syringe needle tube is tapered setting, the side of tapered closed cutting tip is provided with inclined plane, the gradient on inclined plane is less than the tapering of tapered closed cutting tip, and inclined plane is provided with inlet opening.
2. needle for injection according to claim 1, is characterized in that: the gradient of described inlet opening apertura lateralis face equates with the gradient on inclined plane.
