Problems solved by technology

[0002] The existing medical syringes have the following defects. The length of the needle is fixed. For the medical staff who give the patient an injection for the intern for the first time, it is easy to cause the needle to be inserted into the human body incorrectly. That is, when the needle is inserted into the fat layer, the injection cannot be completed. Only Piercing into the muscle layer, the drug solution is introduced into the human muscle tissue through the needle to achieve injection. The depth of needle penetration is different for different fat and thin people. Fat people penetrate deeper, while thin people The penetration is shallow, and beginners cannot control the depth of penetration

Description

Technical field [0001] The invention relates to medical supplies, in particular to a precise liquid medicine injection syringe. Background technique [0002] Existing medical syringes have the following defects. The length of the needle is fixed. For the medical staff who injects the patient for the first time, it is easy to cause the needle to penetrate the human body inaccurately, that is, when the needle penetrates the fat layer, the injection cannot be completed. Into the muscle layer, the drug solution is introduced into the human muscle tissue through a needle to achieve injection. For different fat and thin people, the penetration depth of the needle is different. The fat person penetrates deeper, while the thin person The penetration is a bit shallow, and beginners cannot control the depth of penetration. Summary of the invention [0003] The present invention provides a precise medical liquid syringe that introduces a precise liquid medicine. The purpose of developing th...
