Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp.

[0023] A self-destructing syringe, such as figure 1 , figure 2 As shown, it includes a syringe 2 with an opening 1 on one side, a rubber stopper 3 slidably connected inside the syringe 2 , and a push rod 4 connected to the rubber stopper 3 and passing through the opening 1 .

[0024] A liquid outlet 5 is opened on the side of the syringe 2 away from the opening 1 , and the liquid outlet 5 communicates with the inner cavity of the syringe 2 . When in use, the injection liquid inside the syringe 2 can be pushed out from the liquid outlet 5 through the rubber stopper 3 .

[0025] like figure 2 As shown, the interior of the syringe 2 is integrally formed with a connecting pipe 6 arranged along the axial direction of the syringe 2 , and t...

Abstract

The invention provides a self-destructing syringe. The self-destructing syringe comprises a syringe, a rubber plug and a push rod, wherein the inside of the syringe is provided with a connecting pipecommunicating with a liquid outlet of the syringe, the connecting pipe is provided with a rubber liquid isolation plate in a sleeve manner, the rubber liquid isolation plate divides an inner cavity ofthe syringe into an extrusion cavity and a liquid storage cavity, the inside of the extrusion cavity is provided with springs for supporting the rubber liquid isolation plate, and the inside of the extrusion cavity is provided with puncture needles for piercing the rubber plug. The springs can support the rubber liquid isolation plate, so that when the rubber plug is in contact with the connecting pipe, the rubber liquid isolating plate can abut against the rubber plug, and thereby the injection liquid residue is reduced. Then the rubber plug and the rubber liquid isolation plate continue tobe pushed, and when the rubber liquid isolation plate is in contact with the puncture needles, the puncture needles penetrate into the rubber plug. When the puncture needles completely penetrate the rubber plug, the puncture needles can limit a position of the rubber plug, so that the self-destructing syringe cannot be used again, and the cross-infection is avoided. At the same time, the rubber plug pierced by the puncture needle has poor tightness, and cannot be used to push out an injection solution, so that the repeated use of the self-destructing syringe can be avoided, and the cross-infection is avoided.

Description

technical field [0001] The present invention relates to syringes and, in particular, to a self-destructing syringe. Background technique [0002] A syringe is a medical device that injects liquid medicine into tissues, subcutaneous tissue, blood vessels, and muscles through acupuncture techniques. However, the common syringes currently used clinically can only inject drugs into the human body, they cannot self-destruct, and there is a possibility of repeated use. There is a hidden danger of cross-infection in reusable syringes, which can easily cause the spread of diseases. Contents of the invention [0003] In view of this, the object of the present invention is to provide a self-destructing syringe, which can self-destruct after use to avoid cross-infection. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a self-destruct syringe, comprising a syringe with an opening on one side, a rubber stopper slidingly con...
