Description
Technical field
The present invention relates to a kind of needle for inserting bottle.
Background technology
At present, pistol type needleless injector is used in human injection, the advantage of Needleless injection is to eliminate the fear of the person of being injected to syringe needle, half vaccine consumption can be saved, along with the development of needleless injector, various product life then mutually, there is various types of needleless injector, injection easy to carry is a few days ago pistol type needleless injector accurately, how being injected into by medicinal liquid in the device of specific nozzle or similar nozzle in syringe is indispensable part, existing needle for inserting bottle structure is for being provided with drawing liquid head and drawing liquid stiff end, although this plug bottle device reaches the object of drawing liquid, but drawing liquid head is going deep in medicine bottle, owing to there is no bracing or strutting arrangement, drawing liquid head length is uncontrollable, sucker is arranged at syringe needle, the medicinal liquid drawn is insufficient, in addition, after extraction medicinal liquid, needle for inserting bottle can be extracted out from medicinal liquid bottle, use in order to avoid secondary or avoid cross infection, often require that entry needle must not utilize by secondary after injection, if but needle for inserting bottle can be extracted out, easily cause and again recycle, be unfavorable for patient health.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of easy to operate, avoids the plug bottle device being exclusively used in needleless injector nozzle producing stifled medicine and fall bits.
In order to solve the problems of the technologies described above, the invention provides a kind of needle for inserting bottle, it comprises liquid pumping side, support end and insertion end, described support end is arranged between liquid pumping side and insertion end also in connection status, described liquid pumping side length is 2:1 with the length ratio of insertion end, described liquid pumping side is segmentation structure, described liquid pumping side comprises the first drawing liquid section, second drawing liquid section, 3rd drawing liquid section, 4th drawing liquid section and tip, every section of arrangement from coarse to fine successively, described liquid pumping side and support end link are provided with concave structure, one end, described liquid pumping side is set to inverted cone and is connected with concave structure, two ends, liquid pumping side are provided with at least two drawing liquid holes, described drawing liquid hole is located in the 3rd drawing liquid section
,insertion end is micro-conical cavity structure, described liquid pumping side is connected with insertion end, and described first drawing liquid section is inverted cone-shaped structure, and the first drawing liquid segment length is greater than the thickness of medicine bottle stopper, described second drawing liquid section is column structure, described 3rd drawing liquid section is inverted cone-shaped structure, and described 4th drawing liquid section is column structure, and described tip is conical structure, circular cone bottom surface is connected with the 4th drawing liquid section, described support end is disk structure, and drawing liquid hole open pore size through liquid pumping side passage, and is trapezium structure.Described liquid pumping side, support end and insertion end are made up of makrolon material.
Compared with prior art, the present invention has the following advantages.
Described liquid pumping side length is 2:1 with the length ratio of insertion end, described liquid pumping side is segmentation structure, every section of arrangement from coarse to fine successively, liquid pumping side and support end link are provided with concave structure, one end, described liquid pumping side is set to inverted cone and is connected with concave structure, inverted cone liquid pumping side length is greater than the thickness of medicine bottle stopper, be applicable to all kinds of medicine bottle stopper, and stifled medicine phenomenon can not be produced, one end, described liquid pumping side is set to inverted cone and is connected with concave structure, after once taking out medicine, the liquid pumping side of inverted cone cannot be extracted out from medicinal liquid bottle, prevent secondary from using, avoid cross infection, two ends, liquid pumping side are provided with at least two drawing liquid holes, medicinal liquid is contacted wide with liquid pumping side, the disposable absorption of medicinal liquid is abundant, comparing existingly has pin in syringe needle drawing liquid more convenient operation.
Described support end is arranged at also in connection status between liquid pumping side and insertion end, and described support end is disk structure, and support end just stops that plug bottle device continues to stretch into, and drawing liquid is stablized, can well control medicinal liquid contact area.
Described liquid pumping side, support end and insertion end are made up of makrolon material, this material transparent, and whole plug bottle device is transparent configuration, easily reclaims, is beneficial to environmental protection.
Accompanying drawing explanation
Fig. 1 is the sectional view of needle for inserting bottle of the present invention.
Fig. 2 is the structural representation of needle for inserting bottle of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, a kind of needle for inserting bottle, it comprises liquid pumping side 1, support end 2 and insertion end 3, described support end 2 is arranged between liquid pumping side 1 and insertion end 3 also in connection status, described liquid pumping side 1 length is 2:1 with the length ratio of insertion end, described liquid pumping side 1 is segmentation structure, every section of arrangement from coarse to fine successively, described liquid pumping side 1 is provided with concave structure 5 with support end 2 link, one end, described liquid pumping side 1 is set to inverted cone and is connected with concave structure 5, two ends, liquid pumping side 1 are provided with at least two drawing liquid holes 4, drawing liquid hole 4 open pore size is through liquid pumping side 1 passage, and in trapezium structure, insertion end 3 is micro-conical cavity structure, described liquid pumping side 1 is connected with insertion end 3, described support end 2 is disk structure, described liquid pumping side 1, support end 2 and insertion end 3 are made up of makrolon material.
Be preferably: the insertion end 3 of needle for inserting bottle is inserted on the nozzle of jet injector, insertion end 3 is micro-conical cavity structure, can better to fit nozzle, again medicine bottle stopper is passed in the termination of liquid pumping side 1 after insertion, stop till support end 2, medicinal liquid infiltrate liquid pumping side 1, pull nozzle, medicinal liquid is entered liquid pumping side 1 by drawing liquid hole 4, then flow into insertion end 3 and extract in nozzle.
