Abstract
The injection of a kind of medical closed container constant voltage and suction puncture needle, it comprises the first puncture needle and the second puncture needle, the first needle body that first puncture needle comprises the first syringe needle and is connected with first syringe needle one end, the other end of the first needle body is connected with connecting portion, the 3rd syringe needle that the second puncture needle comprises the second syringe needle, the second needle body be connected with second syringe needle one end and is connected with the second needle body other end; First syringe needle, the second syringe needle and the 3rd syringe needle all have sharp portion, and sharp portion has inclined plane; Opening in the inclined plane of the first syringe needle and the second syringe needle and inclined plane dorsad.When this utility model can solve and extract by syringe the liquid medicine closed in medicine bottle, due to negative pressure cause liquid medicine extract difficulty and by syringe fluid injection to closed medicine bottle time, because malleation causes the problem of liquid infusion difficulty.<i/>
Description
Technical field
This utility model belongs to a kind of injection puncture needle, is specifically related to a kind of medical medical closed container constant voltage injection and suction puncture needle.
Background technology
Now puncture needle on the injector is only made up of the syringe needle on single needle body, needle body top and the connecting portion of needle body bottom, like this when puncture needle inserts the liquid medicine in medicine bottle extraction medicine bottle, vial can be caused to produce negative pressure and negative pressure can be caused constantly to increase along with the continuous extraction of liquid medicine, the liquid medicine in the more difficult extraction medicine bottle of such medical personnel.Puncture needle insert medicine bottle injecting fluid enter in medicine bottle time, vial can be caused to produce malleation and malleation can be caused constantly to increase along with the continuous injection of liquid, the more difficult injecting fluid of such medical personnel is in medicine bottle.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of medical closed container constant voltage injection provided and suction puncture needle, when it can solve and extract by syringe the liquid medicine closed in medicine bottle, due to negative pressure cause liquid medicine extract difficulty and by syringe fluid injection to closed medicine bottle time, because malleation causes the problem of liquid infusion difficulty.
The object of utility model is achieved in that
A kind of medical medical closed container constant voltage injection and suction puncture needle, it comprises the first puncture needle and the second puncture needle, the first needle body that first puncture needle comprises the first syringe needle and is connected with first syringe needle one end, the other end of the first needle body is connected with connecting portion, the 3rd syringe needle that the second puncture needle comprises the second syringe needle, the second needle body be connected with second syringe needle one end and is connected with the second needle body other end;
First syringe needle, the second syringe needle and the 3rd syringe needle all have sharp portion, and sharp portion has inclined plane; Opening in the inclined plane of the first syringe needle and the second syringe needle and inclined plane dorsad.
Further, the top of the first syringe needle and the bottom of the second syringe needle are in same level.
Further, the vertical distance on the top of the first syringe needle and the top of the second syringe needle is 2-8cm.
Preferably, connecting portion upper end is provided with barrier plate.
Preferably, the 3rd syringe needle has inclined plane, and inclined plane obliquely.
This utility model achieves following technique effect:
Adopt said structure, this utility model can the capping well punctured above medicine bottle make puncture needle insert in medicine bottle, and in extraction bottle when liquid medicine air can enter medicine bottle from the second puncture needle, effectively prevent in medicine bottle and produce negative pressure, make whole medicine process of taking out easily simple;
Adopt the top of the first syringe needle and the structure of bottom in same level of the second syringe needle, first by the capping on the second needle pierces medicine bottle, the second needle body is inserted very easily, and then allow the first needle body insert, can reduce the resistance that the first needle body and the second syringe needle enter, that effectively reduces whole puncture needle enters difficulty; The resistance that syringe needle can be allowed to enter linearly increases, and can not produce pause and transition in rhythm or melody sense, be beneficial to operation; When can prevent drawing liquid, the first needle body is extracted into excessive gas simultaneously, affects pumping efficiency.
Adopt the 3rd syringe needle to have inclined plane, inclined plane structure obliquely, like this after whole puncture needle is inserted medicine bottle, can well extract, improve the mobility of puncture needle in medicine bottle.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that this utility model uses schematic diagram.
Detailed description of the invention
A kind of medical medical closed container constant voltage injection and suction puncture needle as shown in Figure 1, it comprises the first puncture needle 1 and the second puncture needle 2, the first needle body 102 that first puncture needle 1 comprises the first syringe needle 101 and is connected with first syringe needle 101 one end, the other end of the first needle body 102 is connected with connecting portion 3, the 3rd syringe needle 203 that the second puncture needle 2 comprises the second syringe needle 201, the second needle body 202 be connected with second syringe needle 201 one end and is connected with second needle body 202 other end; First syringe needle 101 and the second syringe needle 201 have sharp portion, and sharp portion has inclined plane; Opening in the inclined plane of the first syringe needle 101 and the second syringe needle 201 and inclined plane dorsad.
The top of described first syringe needle 101 and the bottom of the second syringe needle 201 are in same level.
The vertical distance on the top of described first syringe needle 101 and the top of the second syringe needle 201 is 2-8cm.
Described connecting portion upper end is provided with barrier plate 4.
Described 3rd syringe needle 203 has inclined plane, and inclined plane obliquely.
Adopt said structure, first this utility model is connected with syringe nipple by connecting portion 3, during use, as shown in Figure 2, first by the capping 501 of the second syringe needle 201 penetration of vials 5, then continue firmly to make the first puncture needle and the second puncture needle enter medicine bottle, ensure that the 3rd syringe needle 203 is outside medicine bottle capping simultaneously, after puncture needle inserts the degree of depth suitable in medicine bottle, the medicinal liquid in medicine bottle is extracted by syringe, this utility model can the capping well punctured above medicine bottle make puncture needle insert in medicine bottle, and in extraction bottle when liquid medicine air can enter medicine bottle from the second puncture needle, effectively prevent in medicine bottle and produce negative pressure, make whole medicine process of taking out easily simple.
