Problems solved by technology

The syringe is composed of a syringe with a small hole at the front end and a matching piston core rod, which is used to inject a small amount of liquid or inject it into areas that are inaccessible by other methods or withdraw it from those places. When the core rod is pulled out The liquid or gas is inhaled from the small hole at the front of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in. Our common syringes for preparing medicines are often not guaranteed after use and discarded, and may cause children to play curiously. Accidentally injured by a needle, once the syringe is used, there is a possibility of contamination, and the contamination may affect the health of the body, which is extremely harmful

Abstract

The invention belongs to the field of intravenous injection medicine blending, and relates to a self-destruction needle cylinder for medicine blending. The self-destruction needle cylinder comprises a shell, a self-destruction needle head cavity is formed in the shell, a replaceable self-destruction needle head is arranged in the self-destruction needle head cavity, the replaceable self-destruction needle head is used for self-destruction of the needle head after use, the needle head can be replaced according to needs before the needle head is used, an injection cavity is formed in the shell, and a needle cylinder self-locking device is arranged in the injection cavity. According to the self-destruction needle cylinder for medicine blending, a conventional liquid medicine extraction mode can be adopted in the aspect of liquid medicine extraction of the needle cylinder, a needle head part can be screwed off, a small amount of liquid medicine can be poured into the needle cylinder, waste caused by the fact that the needle cylinder cannot completely extract the liquid medicine in a small bottle is avoided, after the needle cylinder is used, the needle head and the body part of the needle cylinder can be self-locked, so that the needle cylinder cannot be used for the second time, after the needle cylinder is used, the bottom of the needle cylinder is pressed and rotated, the gel fixing bead on the needle head part can be crushed, the needle cylinder is drawn back into the needle cylinder to complete self-destruction, and potential safety hazards such as mistakenly touching the needle head after the needle cylinder is used are avoided.

Description

technical field [0001] The invention belongs to the field of drug preparation for intravenous injection, in particular to a self-destruct syringe for drug preparation. Background technique [0002] As we all know, the syringe is a common medical appliance, and the appearance of the syringe is an epoch-making revolution in the field of medical appliances. The process of withdrawing and injecting gas or liquid with a needle is called injection. The syringe is composed of a syringe with a small hole at the front end and a matching piston core rod, which is used to inject a small amount of liquid or inject it into areas that are inaccessible by other methods or withdraw it from those places. When the core rod is pulled out The liquid or gas is inhaled from the small hole at the front of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in. Our common syringes for preparing medicines are often not guaranteed after use and discarded, and may cause chi...
