A new type of anti-stab needle cap

1. The present utility model relates to the technical field of medical instruments, in particular to a novel anti-stab needle cap.

Background technique:

2. Needle stick injury is an accidental injury caused by medical staff due to sharp medical tools, which can cause skin damage and is enough to cause the exposed skin to bleed, which has become one of the problems that threaten the safety of medical staff. The top two causes of needle stick injuries are syringes and disposable scalp needles, which are also the medical items that nurses are most exposed to clinically. From clinical experience, the most common cause of needle stick injuries is the time between needle withdrawal and disposal. During the actual nursing operation, after the nurse pulls out the needle and cannot handle it immediately, the needle may be put back into the sheath, but this operation can easily cause needle stick injuries. Therefore, it is necessary to take corresponding measures to reduce the incidence of needle stick injuries caused by the self-contained needle cap of the return needle.

3. In order to solve the problem of needle stick injuries, many medical workers have carried out research. For example, Chinese patent cn215083502u discloses a stab-proof sheath for a syringe needle and a syringe. The technical solution improves both the needle and the syringe. After the injection is completed, the stab-proof sheath is placed on the The head of the syringe rotates the stab shield to wrap the needle to avoid stabbing the caregiver. This improved structure requires the improvement of the structure of the matching syringe, and at the same time, the structure cannot realize the protection of the infusion needle. The infusion needle only contains a small area of hand-held part that is pinched by the fingertips, and the design of the thread matching cannot be realized. At the same time, after the infusion needle is pulled out from the infusion tube, it is directly placed in the stab-proof sheath, which cannot be stabilized, and is still easy to fall off, which is likely to cause re-injury.
