Abstract

The utility model belongs to a medical apparatus, and discloses an injector. The injector is mainly characterized by comprising a needle head, a needle tubing and a propeller, wherein as for the needle tubing, the tubing body at the end with the needle head is connected with the inner cavity of a tubular needle head cap through a fastening ring which is sleeved on the tubing body; a spring is arranged in the inner cavity of the tubular needle head cap; one end of the spring, far away from the needle tubing, is fixed on the inner wall of the tubular needle head cap, and the other end is freely telescopic; and a disinfecting cotton plug is arranged at the front end of the tubular needle head cap. Through the tubular needle head cap added on the original normal injector, the injector disclosed by the utility model constantly keeps the needle head in the tubular needle head cap to prevent the needle head from pollution before and in the injection, and specifically, the needle, when moving away from the tubular needle cap, is disinfected by the disinfecting cotton plug, so that the entire injection process is clean and safe, and is actually guaranteed.

Description

Syringe

Technical field

This utility model belongs to a kind of medical apparatus and instruments, especially a kind of syringe.

Background technology

Syringe is a kind of utensil commonly used in medical apparatus and instruments, and common syringe comprises that syringe needle, needle tubing and three parts of propeller form at present.Although it is simple in structure, a little easy to use that it has, its shortcoming is also very outstanding.Its maximum shortcoming is: other position owing to can often contacting article, underwear, hands and user in using, and caused syringe needle contaminated, malpractice easily occurs.

Therefore, how existing ordinary syringe being carried out to structural innovation and improvement, guarantee that it is not contaminated in the overall process of being injected, is that people thirst for the technical problem solved always.

The utility model content

This utility model is that the technical scheme that its technical problem of solution is taked is a kind of syringe of design, its structure comprises syringe needle, needle tubing and propeller, wherein said needle tubing, its body with needle end is connected with an end of tubular needle head cap inner chamber through a clasp be nested with on body, be provided with a spring in the inner chamber of this end of tubular needle head cap, spring is fixed on the inwall of end of tubular needle head cap away from an end of needle tubing, and other end retractable is provided with the sterilization tampon at the front end of end of tubular needle head cap.

The beneficial effects of the utility model are, owing to having set up an end of tubular needle head cap on ordinary syringe, make syringe needle before injection and the injection in all the time in the end of tubular needle head cap, can do not polluted, especially can be subject to again sterilizing when entry needle leaves the end of tubular needle cap disinfective action of tampon, so the clean and safe in its whole injection process is conscientiously secure.

The accompanying drawing explanation

The overall structure schematic diagram that Fig. 1 is this utility model syringe.

The specific embodiment

Embodiment of the present utility model, referring to Fig. 1, a kind of syringe, its structure comprises: syringe needle 1, needle tubing 2 and propeller 3, and wherein said needle tubing 2, its body with syringe needle 1 end is connected with end of tubular needle head cap 5 inner chambers through a clasp 4 be nested with on body, be provided with a spring 6 in the inner chamber of this end of tubular needle head cap 5, spring 6 is fixed on the inwall of end of tubular needle head cap 5 away from an end of needle tubing 2, and other end retractable is provided with tampon 7 for sterilization at the front end of end of tubular needle head cap.

The using method of this syringe is: at first at the interior suction injection of needle tubing 2 liquid medicine, then will with end of tubular needle head cap 5, connect together with the needle tubing 2 of syringe needle 1, while entering injection stage, continuation by needle tubing 2 in the interior propelling of end of tubular needle cap 5, the syringe needle 1 of needle tubing 2 front portions will be forward, along with the spring 6 in the continuous propelling compression tubulose needle cap 5 of needle tubing 2, until make syringe needle 1 through tampon 7 for needle sterilizing, realize the front needle sterilizing of contact patient skin, finally penetrate patient's muscle.

Claims

1. a syringe, its structure comprises syringe needle, needle tubing and propeller, it is characterized in that described needle tubing, its body with needle end is connected with an end of tubular needle head cap inner chamber through a clasp be nested with on body, be provided with a spring in the inner chamber of this end of tubular needle head cap, spring is fixed on the inwall of end of tubular needle head cap away from an end of needle tubing, and other end retractable is provided with the sterilization tampon at the front end of end of tubular needle head cap.
