Abstract

The invention relates to a needle withdrawing mechanism which can be connected with a medicament container and a manual or electric driving module and can be driven by the driving module to execute injection operation, a base of the needle withdrawing mechanism is provided with a movable connecting part, a needle group, a needle withdrawing operation assembly and a needle retracting operation piece, and the needle withdrawing mechanism is connected with a switching mechanism through the connecting part. The needle set located in the connecting part can be driven by the needle withdrawing operation assembly, stretches out of the base in the mode that the hard needle penetrates through the soft needle, stretches out of the needle and can directly pierce the human body, the hard needle is continuously driven to be separated from the soft needle, and injection of medicine liquid is executed through the driving mechanism. The narrowing operation part can be operated to narrow the connecting part and the soft needle penetrating through the connecting part, so that the needle withdrawing mechanism has excellent operation simplicity and convenience in use.

Description

technical field [0001] The invention relates to a syringe used for the subcutaneous injection of medicament liquid for human body, especially a needle ejection mechanism in the syringe. Background technique [0002] The structure of the syringe currently used for subcutaneous injection of medicinal liquid for human body mainly uses a manually or electrically operated drive module combined with a needle ejection mechanism to connect the medicinal container so that the needle of the needle ejection mechanism can be inserted into the human body for subcutaneous injection. [0003] Existing syringes enable the needle to be temporarily placed in the human body when performing subcutaneous injections on the human body for many times, so as to avoid the discomfort of the human body caused by repeated insertion and extraction of the needle, and it is expected that the human body will not be left in the human body. Needle stick injury, the needle of the syringe is changed to a needle...
