Abstract
The utility model relates to a disposable medical syringe, which comprises a needle cylinder and a push rod, wherein, the front end of the needle cylinder is provided with a syringing port, and the rear side of the push rod is sheathed in the needle cylinder. The utility model has the technical proposal that the front end of the push rod is provided with a sharp object away from the position aligning the syringing port of the needle cylinder. Because of adopting the structure, the utility model can be automatically destroyed after one-time use so that the utility model is ensured to be used only once.
Description
This utility model relates to a kind of Dispoable medical syringe.
The Dispoable medical syringe is because its easy to use being widely used.But existing Dispoable medical syringe still has function of use after once using, this can cause medical cross infection thus with regard to probably being used to repeatedly use by the lawless person, has endangered people health.
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and a kind of Dispoable medical syringe with automatically damaging shape function is provided.
This utility model comprises that front end is provided with the syringe of injection port and by the push rod in the sheathed inserting needle tube in rear, and its technical solution is that the front end at push rod leaves over against the position of the injection port of syringe and is provided with sharp object.
Further technical solution of the present utility model is to be provided with guard column between syringe and push rod.
The height that further technical solution of the present utility model is a sharp object greater than its over against the wall thickness of syringe antetheca.
Adopt the Dispoable medical syringe of said structure, puncture, make syringe lose function of use, thereby guaranteed that it can not be used again after once using owing to after the front end of push rod is provided with sharp object, can cause at the antetheca that uses the back to syringe for the first time.It is that the protection syringe can not cause the sharp object on the push rod that syringe is damaged owing to maloperation makes the push rod action before use that guard column is set between syringe and push rod, and guard column is set simultaneously also can become the sign whether syringe uses for the first time.The height of sharp object greater than its over against the wall thickness of syringe antetheca be to guarantee that sharp object can puncture syringe, syringe is damaged.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of present embodiment.
As shown in the figure, present embodiment comprises that front end is provided with the syringe 4 of injection port 1 and by the push rod 3 in the sheathed inserting needle tube in rear 4, leave over against the position of the injection port 1 of syringe 4 at the front end of push rod 3 and be provided with prong 2, its height greater than its over against the wall thickness of syringe 4 antethecas.The position that reaches on push rod 3 outside the syringe 4 simultaneously is provided with guard column 5, and guard column 5 and push rod 3 are connected by thin layer.
