Problems solved by technology

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 a waste of liquid medicine, and the operator may be injured by a needle
3. Violent activities cause the syringe needle to break

Embodiment Construction

[0009] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0010] by Figure 1-3 Given, the present invention includes a syringe 1, a piston core rod 2 and a steel needle 3. The piston end 2a of the piston core rod 2 extends into the inner cavity of the syringe from the mouth of the rear end of the syringe 1, and the steel needle 3 is installed in the syringe 1. The front end of the needle 3, the inner cavity of the syringe between the liquid inlet of the steel needle 3 and the piston end of the piston core rod constitutes a negative pressure sliding stroke chamber 1a, and the piston core rod slides forward and backward along the length of the inner cavity of the syringe to form a compression injection In the structure, the steel needle 3 is provided with a sliding sleeve 7 fixedly connected to the front end of the needle cylinder 1, the steel needle 3 is sleeved with a sliding sealing column 4...

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, they often need parents to fully position themselves because they do not cooperate with the operation before the operator can inject drugs. However, just after the injection needle enters the muscle, the child will involuntarily engage in activities such as kicking due to the sudden pain. This kind of activity can lead to undesirable consequences: 1. The small range of activity may cause the position of the syringe needle in the muscle to change, damage the muscle tissue, and increase the pain. 2. A large range of movement may cause the needle to come out of the skin, resulting in a waste of liquid medicine, and the operator may suffer needle stick injuries. 3. Vigorous activity causes the syringe needle to break. Therefore, improvement and innovation ...
