Abstract

The invention discloses a safety injector capable of automatically rotating and self-destroying, and belongs to the technical field of syringes. The injector comprises a needle cylinder, a core rod, a needle head base and a stop ring, N first protruding strips are evenly distributed outside the needle head base, a second protruding strip A is arranged on the upper portion in the needle cylinder, a locking protruding block B is arranged in the needle cylinder and located at the position of the stop ring, and second protruding strips are embedded between the two corresponding adjacent first protruding strips so that the needle head base can only move up and down; An L-shaped locking block B matching a locking convex block is arranged outside a stop ring; the locking block is hooked on the upper side of the locking convex block to fix the stop ring on the needle cylinder; A tenon is provided with C rotation driving protruding blocks, and C rotation guiding protruding strips matching rotation driving protruding blocks are arranged in the limiting ring. After injection is completed, the tenon is inserted into the stop ring, the rotation driving protruding block and the rotation guiding protruding strips are matched to enable the stop ring to rotate towards the unlocking direction till the locking protruding block and the locking block are staggered, the core rod and the stop ring are locked, and the core rod is pulled downwards to enable the stop ring and the needle head base to move downwards.

Description

technical field [0001] The invention belongs to the technical field of syringes, in particular to an auto-rotating and self-destructing safety syringe. Background technique [0002] Currently, syringes are the most commonly used and one of the most used medical devices. In recent years, in order to control iatrogenic infectious diseases and avoid adverse consequences such as cross-infection, disposable sterile syringes have been widely used. However, existing disposable syringes all have defects such as being intact after use, reusable, without any safety device, and exposed after injection. On the one hand, it is easy to be used by malicious elements, and the reuse of discarded disposable syringes after use is very easy to cause the spread of viruses and cross-infection; on the other hand, the needles after injection are still left outside. Not only does it cause inconvenience to the handling and destruction of syringe waste, but also accidental injuries to users due to t...
