Abstract
The utility model provides an injector, comprising a needle cylinder provided with a liquid outlet pipe, a needle head with a needle head seat, and a plunger, wherein the outer surface of the needle cylinder is designed into a rough surface, one end of the needle cylinder is provided with the liquid outlet pipe with external threads, the inner hole of the needle head seat is provided with internal threads matched with the external threads of the liquid outlet pipe, the needle head seat is sleeved outside the liquid outlet pipe and is in threaded connection with the liquid outlet pipe, the other end of the needle cylinder is provided with an opening, one end of the plunger is inserted into the opening, and the other end of the plunger is provided with a ring-shaped hand-pushing part. The injector has the beneficial effects that medical personnel can hold the rough surface by hand, thus applying force better, the field of view is clear, and the operation is accurate; when thumb fingers of a user push the hand-pushing part, the fingers can be more stably positioned, and slipping is avoided; and the liquid outlet pipe of the needle cylinder is in threaded connection with the needle head seat, the liquid outlet pipe is spirally screwed with the needle head seat, even the internal pressure is very high, the needle head cannot fall off, and the medicine suction or the medicine injection is very safe, so that the working efficiency is improved, and the working difficulty of workers is relieved.
Description
Technical field
This utility model belongs to technical field of medical instruments, especially relates to a kind of syringe.
Background technology
The syringe of present clinical use generally comprises syringe and plunger, by pressure the liquid in the syringe is gone in the human body by needle injection.Its outer surface is shiny surface entirely, when hands is injected in the body, points bad assurance, firmly, usually need the another hands to catch the syringe co-operate, but such two handss has often blocked the staff's oneself visual field, makes operation inaccurate, and influence is treated.Syringe one end of syringe is provided with drain pipe, and syringe needle is connected on the drain pipe by pinhead sleeve, and such syringe needle is connected firm inadequately with injector syringe, in inhaling the medicine process, owing to reasons such as internal pressure are excessive, the phenomenon that syringe needle comes off can appear, waste medicinal liquid this moment, adds heavily to the difficulty of the work; The other end has opening so that plunger inserts, and plunger one end inserts in this opening, and the other end is provided with a hand push portion, moves to allow user promote plunger by hand push portion.Existing hand push portion all adopts circular flat, and user all is to promote this hand push portion with thumb, and this thumb that just causes user causes thumb to produce on this hand push portion surface and slides when promoting circular flat hand push portion.
Summary of the invention
The purpose of this utility model provides a kind of syringe of simple in structure, easy to use, syringe needle difficult drop-off.
The technical solution of the utility model is: a kind of syringe, comprise the syringe that has drain pipe, the syringe needle that has needle holder and plunger, the outer surface of described syringe is designed to matsurface, the one end is provided with drain pipe, described drain pipe has external screw thread, the endoporus of described needle holder is provided with the female thread that matches with the external screw thread of drain pipe, described needle holder is coated at drain pipe and is threaded with drain pipe, the described syringe other end has opening, described plunger one end inserts in this opening, and the described plunger other end is provided with annular hand push portion.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, when giving patient injection, because the hand-held matsurface of medical worker, can be good at firmly, and need not two hands co-operate, making to get a clear view, operation is accurately, the thumb of user is when promoting hand push portion, can make finger locating more stable, prevent to slide, and the drain pipe of syringe be threaded with needle holder, both tighten by spiral, even internal pressure is very high like this, syringe needle can not come off yet, and inhales medicine or injects very safe, increase work efficiency, alleviate staff's work difficulty.
Description of drawings
Fig. 1 is the structural representation of a kind of syringe of the present utility model
Among the figure:
1, drain pipe 2, syringe 3, matsurface
4, needle holder 5, syringe needle 6, plunger
7, annular hand push portion
The specific embodiment
As shown in Figure 1,
Technical solutions of the utility model are: a kind of syringe, comprise the syringe 2 that has drain pipe 1, the syringe needle 5 that has needle holder 4 and plunger 6, the outer surface of described syringe 2 is designed to matsurface 3, the one end is provided with drain pipe 1, described drain pipe 1 has external screw thread, the endoporus of described needle holder 4 is provided with the female thread that matches with the external screw thread of drain pipe 1, described needle holder 4 is coated at drain pipe 1 and is threaded with drain pipe 1, described syringe 2 other ends have opening, described plunger 6 one ends insert in this opening, and described plunger 6 other ends are provided with annular hand push portion 7.
The work process of this example: in use, syringe needle 5 and drain pipe 1 spiral are tightened, even internal pressure is very big, syringe needle 5 can not come off yet.When giving patient injection, medical worker's finger is controlled the matsurface 3 of syringe 2 outer surfaces, and by thumb press annular hand push portion 7, cooperates palm injectable drug in the patient body, and after injection finished, finger was held matsurface 3, cooperated palm, extracted syringe needle 5 and got final product.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to this utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
