Description
Technical field
This utility model relates to field of medical auxiliary equipment, is specifically related to a kind of syringe of medical double-deck syringe needle.
Background technology
Syringe has become one of most popular apparatus of medical field, be mainly used in as injectable drug in patient body, but current syringe is when extraction medicine, the external condition meeting contaminated pinheads such as medicine bottle, use contaminated syringe needle can bring in patient body by pathogenic bacteria when injection, in addition in part medicine bottle opening process, glass or rubber fines can be made to enter into the liquid, common syringe cannot by this type of contaminant filter, and such medicinal liquid can cause significant damage to patient body.
Summary of the invention
For overcoming described deficiency, the purpose of this utility model is to provide that a kind of structure is simple, preventing pollution syringe needle the syringe of medical double-deck syringe needle with filtering function.
This utility model solves the technical scheme that its technical problem adopts: a kind of syringe of medical double-deck syringe needle, comprise piston, syringe, needle assembly, described needle assembly comprises interior syringe needle, outer syringe needle, needle holder, defecator, the osculum end of described syringe is provided with interior syringe needle, outer syringe needle is provided with outside described interior syringe needle, described outer syringe needle root is provided with needle holder, described defecator is horn-like, described defecator big opening end is fixed on outer needle wall, and described defecator osculum end is inserted in interior syringe needle away from syringe one end.
Further, described defecator big opening end is provided with drainage screen, can effective filtering liquid medicine impurity.
Further, described needle holder and syringe osculum end adopt the mode that removably connects, and close contact, prevent the situation of gas leakage.
This utility model has following beneficial effect: structure is simple, can effectively protect syringe needle not contaminated, effectively filters, ensures quality of liquid medicine, be conducive to patient body and recover, can be used as disposable product, be conducive to applying medicinal liquid.
Accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model.
Fig. 2 is the schematic cross-section of needle assembly.
In figure, 1 needle assembly, the outer syringe needle of 1-1,1-2 defecator, syringe needle in 1-3,1-4 needle holder, 2 syringes, 3 pistons.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.
The syringe of a kind of medical double-deck syringe needle according to Fig. 1,2, comprise piston 3, syringe 2, needle assembly 1, described needle assembly 1 comprises interior syringe needle 1-3, outer syringe needle 1-1, needle holder 1-4, defecator 1-2, the osculum end of described syringe 2 is provided with interior syringe needle 1-3, outer syringe needle 1-1 is provided with outside described interior syringe needle 1-3, described outer syringe needle 1-1 root is provided with needle holder 1-4, described defecator 1-2 is horn-like, it is inner that described defecator 1-2 big opening end is fixed on outer syringe needle 1-1, and described defecator 1-2 osculum end is inserted in interior syringe needle 1-3 away from syringe 2 one end.
Further, described defecator 1-2 big opening end is provided with drainage screen, can effective filtering liquid medicine impurity.
Further, described needle holder 1-4 and syringe 2 osculum end adopt and removably connect with snap fit, and close contact, prevent the situation of gas leakage.
This utility model in use; needle assembly 1 is inserted in medicine bottle; medical worker extracts in medicinal liquid process, and medicinal liquid after filtration device 1-2 filters, and enters syringe 2 from interior syringe needle 1-3; effectively reach filtration object; before liquid medicine injection, first medical worker pinches needle holder 1-4, takes off needle holder 1-4, outer syringe needle 1-1 and defecator 1-2; then in using, syringe needle 1-3 injects patient, thus reaches thus can reach the not contaminated object of protection syringe needle.
This utility model is not limited to described embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with this utility model, all falls within protection domain of the present utility model.
Technology, shape, structure part that this utility model is not described in detail are known technology.
