Abstract
The utility model discloses a syringe, which comprises a syringe body and a needle, wherein the syringe body is provided with a liquid outlet tube, and the needle is provided with a needle seat. The needle seat is sleeved outside the liquid outlet tube and connected with the liquid outlet tube in a threaded manner; the liquid outlet tube of the syringe body is connected with the needle seat in a threaded manner; and the liquid outlet tube and the needle seat are screwed up spirally, so that the needle cannot fall off even if internal pressure is extremely high, and medicine suction or injection is extremely safe.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of syringe.
Background technology
Conventional injector is generally by syringe body with syringe needle is split type constitutes, and the syringe body front end face is provided with drain pipe, and syringe needle is socketed on the drain pipe by needle holder.But such syringe needle is firm inadequately with being connected of syringe body, in inhaling medicine or injection process, owing to reasons such as internal pressure are excessive, the phenomenon that syringe needle comes off sometimes can occur, and wastes medicinal liquid this moment, has increased work difficulty.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of syringe, in inhaling medicine or injection process, can avoid syringe needle to come off.
Syringe of the present utility model comprises syringe body that has drain pipe and the syringe needle that has needle holder, and described needle holder is coated at drain pipe and is threaded with drain pipe.
Further, described drain pipe leading portion is a bullet, and back segment is for being with externally threaded cylinder, and the endoporus leading portion and the described bullet of described needle holder are sealed and matched, and back segment is provided with the female thread that matches with the external screw thread of described drain pipe;
Further, described needle holder outer surface is provided with axial lug, nib.
The beneficial effects of the utility model are: be threaded between the drain pipe of syringe body and the needle holder, both tighten by spiral, even internal pressure is very high like this, syringe needle can not come off yet, and inhale medicine or inject as safe as a house; In addition, the cone seal between drain pipe and the needle holder has partly improved sealing effectiveness, has avoided air admission.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing this utility model is described in further detail, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A place enlarged drawing of Fig. 1.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A place enlarged drawing of Fig. 1; As shown in the figure, syringe of the present utility model comprises syringe body 2 that has drain pipe 1 and the syringe needle 4 that has needle holder 3, and described needle holder 3 is coated at drain pipe 1 and is threaded with drain pipe 1; During use, needle holder and drain pipe spiral are tightened, even internal pressure is very high like this, syringe needle can not come off yet, and inhales medicine or injects as safe as a house.
In the present embodiment, described drain pipe 1 leading portion is a bullet, and back segment is the cylinder of band external screw thread 1a, and the endoporus leading portion and the described bullet of described needle holder 3 are sealed and matched, and back segment is provided with the female thread that matches with the external screw thread 1a of described drain pipe 1; Described drain pipe 1 leading portion is a section away from syringe body 2, and back segment is a section near syringe body 2; The endoporus leading portion of described needle holder 3 is a section of close syringe needle 4, and back segment is a section away from syringe needle 4; Cone seal between drain pipe 1 and the needle holder 3 has partly improved sealing effectiveness, has avoided air admission.
In the present embodiment, described needle holder 3 outer surfaces are provided with axial lug, nib (not drawing among the figure); Axially lug, nib increases friction, can avoid skidding in the process of turn needle holder 3.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by this utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
