Abstract

A safety syringe comprises a needle cylinder. The front end of the needle cylinder is connected with a needle head, a pushing rod is arranged in the needle cylinder, the front end of the pushing rod is fixedly connected with a piston, a plurality of sharp needles are embedded in the piston, the tips of the sharp needles penetrate through a side wall of the piston and abut against an inner wall of the needle cylinder. The safety syringe has the advantages that when a patient is injected, the pushing rod moves forward, due to the fact that the tooth disc is fixedly connected with the pushing rod, the tooth disc also moves forward; due to the fact that the tips of the sharp needles penetrate through the side wall of the piston and abut against the inner wall of the needle cylinder, the tooth tips scratch the inner wall of the needle cylinder when the piston moves forward, and the syringe is marked and has the recycling value no longer. Therefore, the safety syringe is very safe in use.

Description

Safety injector

Technical field

This utility model relates to a kind of device of penetrating, and relates in particular to a kind of safety injector.

Background technology

The syringe that uses at present mostly is disposable product, but some people is in order to speculate, and repacks after will reclaiming with the syringe of crossing and sells, and the sanitary condition of obvious this syringe does not reach instructions for use, certainly will threaten patient's life security.

The utility model content

This utility model provides a kind of safe safety injector that uses for deficiency.

The technical scheme that this utility model solves the problems of the technologies described above is as follows:

A kind of safety injector comprises syringe, and the syringe front end is connected with syringe needle, is provided with push rod in the syringe, and the push rod front end is fixedly connected with piston, it is characterized in that, is embedded with many tips of a root pin in the piston, and the needle point of prong passes and withstands on the syringe inwall from the sidewall of piston.

The beneficial effects of the utility model are: when giving patient injection, the piston driving prong travels forward, because the needle point of prong passes and withstands on the syringe inwall from the sidewall of piston, therefore in the process of piston advances forward, prong can stay cut at the inwall of syringe, and this just gives with the syringe of crossing and has done labelling, makes it no longer have the value of recycling, therefore, it is very safe using syringe described in the utility model.

Description of drawings

Fig. 1 is structural representation of the present utility model.

In the accompanying drawing:

1, syringe needle; 2, syringe; 3, piston; 4, prong; 5, push rod.

The specific embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining this utility model, is not be used to limiting scope of the present utility model.

A kind of safety injector as shown in Figure 1, comprises syringe 2, syringe 2 front ends are connected with syringe needle 1, are provided with push rod 5 in the syringe 2, and push rod 5 front ends are fixedly connected with piston 3, be embedded with many tips of a root pin 4 in the piston 3, the needle point of prong 4 passes and withstands on syringe 2 inwalls from the sidewall of piston 3.

Claims (1)
