Description

An infusion needle structure

technical field

The utility model relates to a needle structure, which belongs to the medical field.

Background technique

Infusion needles are the most commonly used items in hospitals. The existing infusion needles are equipped with a protective sleeve before use, and the sleeve is thrown away when used. However, there is no corresponding protection for the needle after use. It is easy to Injury to others, especially for carriers of infectious diseases, if they accidentally injure others, it is easy to infect others with the disease, and there is a great medical hidden danger.

Utility model content

The purpose of this utility model is to provide an infusion needle structure to solve the problem that the existing infusion needles have no corresponding protection/prevention measures after use, and the needles are easy to accidentally injure people, especially if the needle user is a carrier of infectious diseases. It is easy to infect other people with diseases, and there is a problem of great potential safety hazard.

The scheme of the utility model is as follows: an infusion needle structure, including a needle body and a needle handle, the needle handle is fixed at the end of the needle body, a protective sleeve is set on the needle body, and the length of the protective sleeve is 1/2 of the length of the needle body. 1/5-1/2, the side wall of the protective sleeve is provided with a sleeve limit hole, and the side wall of the needle tip of the needle body is provided with a limit protrusion matching the sleeve limit hole.

Preferably, the difference between the inner diameter of the protective sleeve and the outer diameter of the needle body is less than 2mm;

Preferably, the difference between the inner diameter of the protective sleeve and the outer diameter of the needle body is 0.5mm;

Preferably, the side of the needle handle facing the needle end is provided with a sleeve limiting groove, and when the protective sleeve slides to the needle handle side to the bottom, one end of the protective sleeve is clamped in the sleeve limiting groove on the needle handle, When the needle is in use, the protective sleeve can be effectively positioned to prevent the protective sleeve from hindering the use of the needle;

Preferably, a sleeve handle is provided on the protective sleeve;

Preferably, the protective sleeve is made of plastic or latex.

Compared with the prior art, the utility model has the main advantage that the needle head is simple in structure and low in cost, and a protective sleeve is arranged on the needle head body, so that the needle head can be covered by the protective sleeve before and after use, and the When using the needle, the protective sleeve does not need to be separated from the needle body, which is very convenient to use and avoids the problem of easy injury caused by the needle without corresponding protection measures after use, thereby avoiding the infection/disease transmission caused by the needle injury, Effectively eliminate potential safety hazards, suitable for popularization and application in the medical field.
