Problems solved by technology

[0003] First, needles are easily contaminated
[0004] When the medical staff is giving an injection, they open the packaging bag of the disposable syringe and remove the needle cap. At this time, the hands of the medical staff are easy to touch the needle, causing contamination of the needle, thus bringing bacteria or even germs to the injected patient. nosocomial infection
[0005] Second, it is easy to stab medical staff
According to a group of surveys, the rate of nurses wearing gloves in daily nursing operations is low. Although most nurses can gently squeeze out the local blood of the wound, clean and disinfect it in time after the injury, needlestick injury is a kind of skin deep enough to cause pain. Accidental injury where the injured person is infected, blood or bodily fluids contaminated with pathogens are inoculated into the injured person

Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment the technical scheme of the present invention is described:

[0028] like figure 2 As shown, a safety syringe includes a needle 1, the needle includes a needle point 101, a needle barrel 102 and a needle plug 103, and also includes a transparent retractable needle cover 2 (such as image 3 shown), the needle sheath 2 is set on the needle head 1, one end of the needle sheath 2 is connected to the needle pin 103, the other end of the needle sheath 2 is an opening, and the length of the needle sheath 2 is It is satisfied that the needle tip 101 is covered inside the needle sheath 2, that is, the end of the needle sheath 2 close to the needle tip 101 is longer than the end of the needle tip 101, preferably 2 to 3 mm longer. One end of the needle sheath 2 close to the needle tip 101 is provided with a fixing ring 201 , the fixing ring 201 and the needle sheath 2 are integrally designed and the thickness of the f...

Abstract

The invention relates to a safe syringe which comprises a needle and a transparent contractile needle sleeve, wherein the needle comprises a needle tip, a needle rod and a needle bolt; the needle sleeve is sleeved on the need tip; one end of the needle sleeve is connected with the needle bolt, and the other end of the needle sleeve is open; and length of the needle sleeve meets the condition that the needle tip is sleeve in the needle sleeve. As for patients, since hands of a medical staff can not be in direct contact with the needle before injection through the protection of the needle sleeve, and the pollution to the needle is prevented. As for the medical staff, the medical staff can not be stabbed before injection through the protection of the needle sleeve; besides, because the needle sleeve is the contractile sleeve, the needle sleeve can be automatically restored to the original state after injection, and the needle is protected, thereby greatly reducing the stabbed probability of the medical staff.

Description

【Technical field】 [0001] The technical solution of the present invention relates to a syringe, in particular to a syringe that is safer to use. 【Background technique】 [0002] According to literature review and clinical research, the disposable syringes used in hospitals at all levels in China are composed of needle caps, needles and syringe bodies. Clinically, there are two main problems with this kind of syringes: [0003] First, needles are easily contaminated. [0004] When the medical staff is giving an injection, they open the packaging bag of the disposable syringe and remove the needle cap. At this time, the hands of the medical staff are easy to touch the needle, causing contamination of the needle, thus bringing bacteria or even germs to the injected patient. cause nosocomial infection. [0005] Second, it is easy to stab medical staff. [0006] The first type of needlestick injury is before injecting the patient. If the needle pricks the medical staff at this t...
