Abstract
A self-locking type disposable needle tube mainly resolves the problem that an existing injection needle tube cannot prevent repeated usage. The self-locking type disposable needle tube is characterized in that an annular sawtooth boss (3) is arranged outside the rear of a push rod (1), an inclined surface is arranged on the boss (3), an annular groove (4) is disposed in the rear of the needle tube (2), and an inclined surface is arranged on the groove (4). The self-locking type disposable needle tube has the advantages that the needle tube realizes self-locking and cannot be used repeatedly.
Description
Technical field:
This utility model relates to a kind of medical needle tubing, especially self-locking disposable needle tubing.
Background technology:
Along with the development of society, it is very common thing that injection is cured the disease.Injection needle is important medical apparatus in injection process.And existing injection needle is easy to be repeated use because reasons in structure can't prevent to reuse, and causes germina infection, even life threatening.
The utility model content:
Can't prevent reusable problem in order to solve existing injection needle.This utility model provides a kind of self-locking disposable needle tubing.This self-locking disposable needle tubing has the not re-usable characteristics of self-locking.
The technical solution of the utility model is: this self-locking disposable needle tubing comprises that needle tubing is with push rod.The circular saw boss is arranged outside the push rod rear portion, is the inclined-plane above the boss; Needle tubing has annular groove in the rear portion, is the inclined-plane above the groove.
The utlity model has following beneficial effect: this self-locking disposable needle tubing is at first owing to adopt and to be provided with the circular saw boss and the annular groove that match at push rod and needle tubing rear portion and to optimize structure.Utilize the circular saw boss to be stuck in and produce self-lock mechanism in the annular groove, make push rod to take out, reach the disposable purpose of needle tubing, and simple in structure, easy to use, safe and reliable, be applicable to the injection use.This self-locking disposable needle tubing has the not re-usable characteristics of self-locking thus.
Description of drawings:
Accompanying drawing 1 is this utility model structural representation.
1-push rod among the figure, 2-needle tubing, 3-boss, 4-groove.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this self-locking disposable needle tubing comprises that needle tubing 2 is with push rod 1.Push rod has circular saw boss 3 outside 1 rear portion, is the inclined-plane above the boss 3; Needle tubing has annular groove 4 in 2 rear portions, is the inclined-plane above the groove 4.
During actual the use; Promoting push rod 1 moves forward, because above the boss 3 is the inclined-plane, push rod 1 can move forward, after having injected, when just push rod 1 is shifted the end onto, when thinking outside pull push rod 1, because above the groove 4 is the inclined-plane, and circular saw boss 3 is entered in the annular groove 4, just in time is stuck in the annular groove 4, push rod 1 can't be fallen back, realize the function that this self-locking disposable needle tubing again can't use.
This self-locking disposable needle tubing has been obtained remarkable result by clinical practice.
