Description

Technical Field

[0001] The present invention relates to the technical field of injection equipment, in particular to a subcutaneous injection fixer and an automatic injection system thereof. Background Art

[0002] Subcutaneous injection is a method of administering drugs by injecting them directly into the fat layer under the skin. This method is often used in situations where rapid absorption is required but the drug is not expected to enter the blood circulation immediately. When performing subcutaneous injections, areas on the body with thicker fat layers and fewer blood vessels are usually selected. Common injection sites include the abdomen (avoiding the 5 cm range around the navel), the outer thighs, the back of the upper arms, etc. This can reduce the risk of damage to nerves and blood vessels during the injection process and help the drug to be better absorbed. Subcutaneous injections are widely used in the fields of insulin injections, immunotherapy, and vaccine injections.
