Abstract
The utility model discloses a self-destruction type disposable syringe which comprises an injection cylinder, an injection rod and a self-locking mechanism, wherein, the head part of the injection rod is provided with a plug, and the plug is connected with the injection rod into a whole. The utility model has the characteristics of simple manufacture technology, low production cost, stable sealing performance, etc.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly to a kind of improvement of re-use preventing once-used syringe.
Disposable syringe has the characteristics of health easy to use, safe, is subjected to people's welcome deeply.But some user is often reused for cost saving, so just may cause the cross infection of patient's virus, has lost the meaning that " disposable " uses.At present, many people provide the technical conceive of some re-use preventing once-used syringes, have in addition implemented.But these re-use preventing once-used syringes have increased its manufacturing cost more or less, and user is caused the certain economic burden.
The purpose of this utility model is at the problems referred to above, and the structure of re-use preventing once-used syringe is done certain improvement, and its serviceability is improved, and reduces its manufacturing cost again.
The purpose of this utility model realizes by following technical proposal: this re-use preventing once-used syringe comprises injection rod in injection tube, the injection tube inner chamber and the self-locking mechanism between injection tube and the injection rod, the injection rod head is provided with chock plug, and chock plug and injection rod are connected as a single entity.
This re-use preventing once-used syringe adopts plastics to make.Because chock plug and injection rod are connected as a single entity, can disposablely be shaped, therefore with on the ordinary syringe adopt rubber stopper to compare, have the advantages that manufacturing process is simple, production cost is low.Simultaneously, adopt this structure can guarantee that the sealing property between injection tube and the chock plug is stable, push-and-pull is light, has improved the result of use of syringe.
Below in conjunction with accompanying drawing this utility model is elaborated.
Fig. 1 is the cutaway view of re-use preventing once-used syringe.
As shown in the figure, this syringe comprises injection tube (1), injection rod (2), chock plug (3) and self-locking mechanism.In the present embodiment, self-locking mechanism is made up of retaining sleeve (4) that is fixed on injection tube (1) inner chamber rear portion and the conical convex shoulder (5) that is arranged on injection rod (2) afterbody.During use, at first, push ahead injection rod (2) then, make the convex shoulder (5) of injection rod (2) afterbody pass through retaining sleeve (4), thereby finish whole injection process in medicinal liquid suction injection tube (1) inner chamber.Because retaining sleeve (4) withstands convex shoulder (5), make and use once by syringe back injection rod (2) can not withdraw from, unless damage syringe.In addition, self-locking mechanism also can adopt other structure.
Claims (2)
1, a kind of re-use preventing once-used syringe, comprise injection rod (2) in injection tube (1), injection tube (1) inner chamber and the self-locking mechanism between injection tube (1) and the injection rod (2), it is characterized in that injection rod (2) head is provided with chock plug (3), and chock plug (3) is connected as a single entity with injection rod (2).
2, re-use preventing once-used syringe according to claim 1 is characterized in that described self-locking mechanism is made up of retaining sleeve (4) that is fixed on injection tube (1) inner chamber rear portion and the conical convex shoulder (5) that is arranged on injection rod (2) afterbody.
