Safe disposable injection needle for children

Abstract

The invention relates to a safe disposable injection needle for children which can effectively resolve problems arising from quick and safe intramuscular injection of children. The technical scheme is characterized in that the outside of a steel needle is provided with a sliding sleeve fixedly connected to the front end of a needle cylinder; the steel needle is equipped with a sliding seal column capable of sliding forward and backward along the length direction of the steel needle in a sleeving manner; a needle storage sleeve fixed with the sliding seal column is arranged between the sliding sleeve and the steel needle; the front end of the needle storage sleeve stretches out of the sliding sleeve; a sleeve pipe is connected to the front end surface of the seal column; the sleeve pipe is fixed with the front end of the needle storage sleeve and stretches out of the front end of the needle storage sleeve; and the steel needle stretches into an inner cavity of the needle storage sleeve, penetrates through the seal column and then stretches into the inner cavity of the sleeve pipe forward. After injection, a needle tip of the steel needle is protected by the sleeve pipe, which prevents needle-stick injuries. After needle insertion, the needle is fixed by a location cover and is precluded from shaking. Injection is carried out in such a manner that the sliding sleeve drives the steel needle to be away from a human body. The safe disposable injection needle for children is an innovative product of an injector due to safety and reliability, convenient application and excellent effect.

Description

technical field [0001] The invention relates to an injection needle, in particular to a disposable safety injection needle for children. Background technique [0002] In clinical work, when children are injected intramuscularly, because they do not cooperate with the operation, it is often necessary for the parents to fully position themselves before the operator can inject the drug. However, just after the injection needle enters the muscle, due to sudden pain, the child will involuntarily produce activities such as kicking. This kind of activity will lead to adverse consequences: 1. The range of activity is small, which may cause the position of the syringe needle to change in the muscle, damage the muscle tissue, and aggravate the pain. 2. If the range of activity is large, the needle may come out of the skin, resulting in waste of liquid medicine, and the operator may be injured by a needle. 3. Violent activities cause the needle of the syringe to break. Therefore, th...
