Abstract
The utility model discloses a safe injector comprises an injector body and a needle head protection sleeve, wherein the needle head protection sleeve is sleeved on a tube body of the injector body, an upper locating bayonet and a lower locating bayonet are arranged on the outer side wall of the tube body of the injector body, the needle head protection sleeve is sleeve-shaped, an axial sliding groove is formed in one lateral face, and the upper end and the lower end of the sliding groove are respectively provided with a locating clamping groove. The safe injector is simple in structure, convenient to use and operate and capable of repeatedly acting, the hands do not need to make contact with a needle head, the safety coefficient is high, the needle head is prevented from being polluted by the outside environment, the situation that an operator is punctured to be injured when operations are carried out carelessly is avoided, and other people are also prevented from being injured.
Description
Technical field
This utility model relates to the improvement of syringe construction, specifically a kind of safety injector that has needle guard.
Background technology
The syringe that general curative is used normally is arranged with a sheath in needle section, and before syringe used, this sheath placed on the needle stand, and syringe needle is coated.Medical personnel's injection operation on the practice, at first in the nursing station sheath is taken off, extracts medicament, delivering to the ward again is patient injection, in this section process, for avoiding recovering sheath by the risk of needle sting, or safety shield limits the job requirements that can not recover for once using, sheath places in addition on one side and does not use, cause syringe needle to present naked state, so, also improved the probability that needle sting people or syringe needle are subjected to outside contamination relatively.Then use protecting cover to cover back again after finishing or use disposable high-safety protecting cover when injection, be wounded by stabbing to prevent other staff, not only in trouble and the operation owing to around the continuous contact needle of hand, so there is certain risk.
The utility model content
The purpose of this utility model provides a kind of safety injector, prevents syringe needle by outside contamination, avoid simultaneously medical personnel because of careless manipulation by needle sting.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Safety injector, comprise syringe body and needle guard, described needle guard is placed on the body of syringe body, the body lateral wall of described syringe body is provided with two positioning clamping pin up and down, described needle guard is the cover tubular, be provided with axial chute in the side, and be respectively arranged with locating groove at the upper and lower side of chute.
The beneficial effects of the utility model are:
This utility model is simple in structure, use easy to operate, but perseveration does not need the contact pilotage head that catches, the safety coefficient height prevents syringe needle by outside contamination, avoid medical personnel because of careless manipulation by needle sting, also avoid injuring other people.
