Abstract

A needle protection device with a slideable sleeve (2) and a safety syringe using the needle protection device, which are simple in structure and low in costs and can prevent occurrence of accidental sticks of a needle tube (6) upon use and after use and can prevent the needle from reuse after use. The needle protection device comprises a collar (1) and a slideable sleeve (2). The collar (1) can be sleeved on the needle seat (8) in a fixed manner. The slideable sleeve (2) is in a cylindrical shape, has an upper end portion (22) and a lower end portion (23), and can be sleeved on the collar (1) and slide between a retracted position and an extended position along an outer surface of a boss (12), wherein an outer surface of the collar (1) and an inner surface of the lower end portion (23) of the slideable sleeve (2) are respectively formed with mutually matching locking mechanisms. When the slideable sleeve (2) is at the extended position, it can be locked on the collar (1) in an inseparable manner.

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 or a safety syringe 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 c...
