Description

Auxiliary propeller for a syringe

technical field

The invention belongs to the field of medical equipment, in particular to an auxiliary propeller of a syringe.

Background technique

Generally speaking, when patients need to inject drugs, they are injected by medical staff, but there are also some patients with special diseases, because they often need to be injected subcutaneously and need to be injected by the patients themselves, such as subcutaneous injection of low molecular weight heparin in obstetric patients, diabetic patients When injecting insulin, it is necessary to pay attention not to insert the needle too deeply, in order to prevent the drug from being inserted into the muscle from being absorbed too quickly and causing the patient to feel uncomfortable. The correct injection method for hypodermic injection is generally to pinch the skin with one hand, and then tilt the syringe at a 45-degree angle to inject. At the same time, it is necessary to pay attention that the needle should not be pierced too deeply to avoid piercing the muscle. It is skilled and difficult for medical staff to operate. It is wrong, but for the patient himself, the operation is not proficient, either he is not very good at injection, or it is easy to inject the needle too deeply into the muscle, and the patient is not easy to control when injecting on himself, and it is difficult to see clearly. .
