Abstract

The invention discloses a pin head protective device and a safety pin assembly using the same. The pin head protective device and the safety pin assembly is simple structure, low in cost, capable of preventing that accidental puncture occurs when in use and after being used, and capable of preventing a pin head from being reused after being used. The pin head protective device comprises a neck ring and a sliding sleeve. The neck ring is capable of being sleeved on a pin seat in a fixed mode, and the sliding sleeve is in a drum shape and comprises an upper portion (22) and a lower portion (23) and can be sleeved on the neck ring and slide between a retraction position and a protruding position along the outer surface of a boss. The outer surface of the neck ring (1) and the inner surface of the lower end portion (23) of the sliding sleeve (2) are respectively provided with a lock mechanism, the lock mechanisms are matched with each other, and when being in the protruding position, the sliding sleeve (2) can be locked on the neck ring (1) in an inseparable mode.

Description

technical field [0001] The invention relates to a needle protection device, especially a needle protection device capable of preventing accidental stabbing of needles used in medical instruments such as syringes and blood collection devices, and a safety needle assembly provided with the needle protection device. Background technique [0002] In medical practice, medical devices with sharp needles are widely used, such as syringes, blood collection devices and the like. These medical devices are not only used and handled by professionals in medical institutions, but also often used and handled by non-professionals at home, such as self-injection of insulin by diabetic patients. [0003] Because the needles of medical instruments such as syringes are exposed outside after use, it is easy to stab the relevant personnel, which causes great difficulties in collection and processing. Such puncture wounds can also cause infection with germs. Also, there is a risk of cross-infect...
