Description

An insulin injection needle

Technical Field

The utility model relates to the field of medical insulin injection tools, in particular to an insulin injection needle.

Background technique

Diabetes is a metabolic disease characterized by high blood sugar. High blood sugar is caused by defects in insulin secretion or its biological function, or both. Long-term high blood sugar leads to chronic damage and dysfunction of various tissues, especially eyes, kidneys, heart, blood vessels, and nerves.

There is currently no cure for diabetes, and patients need to be given insulin injections to control the disease. Existing ordinary insulin needles are generally only wrapped in outer packaging. After the packaging is removed, the needle is exposed outside, which can easily cause punctures to patients and expose the needle to the air, which may be contaminated. At the same time, when using existing insulin needles, patients are required to prepare sterilized alcohol cotton swabs separately. If the patient forgets to prepare the cotton swab, direct injection will have the risk of infection, causing inconvenience to the patient or even serious injury.

Therefore, there is a need for an insulin injection needle that is integrated with a disinfection device, will not accidentally injure the patient, and can well protect the needle from being exposed to the air.

Utility Model Content

In order to solve the above problems, the utility model proposes an insulin injection needle, which is integrated with a disinfection device, will not accidentally injure the patient, and can well protect the needle from being exposed to the air, is convenient for patients to use, and has strong safety.

A connecting ring is provided on one side wall of the needle base, and the connecting ring is located on the outside of the needle tube. A telescopic tube is fixedly connected to one side of the connecting ring, and a spring is provided in the telescopic tube. One end of the spring is fixed to the top of the needle base, and the other end of the spring is fixedly connected to the telescopic column. One end of the telescopic column is inserted in the telescopic tube. A sliding hole is opened in the middle of the telescopic column, and one end of the needle tube is located on the inner side of the sliding hole. A protective tube is sleeved on the outer wall of the connecting ring, and a disinfection assembly is clamped on one end of the protective tube.

In one embodiment, the disinfection assembly includes a disinfection cover, an alcohol chamber, a sealing film, a placement groove, a clamping wall and disinfection cotton. The clamping wall is clamped on the inner side of one end of the protective tube. The inner side of the clamping wall is provided with a placement groove. Disinfection cotton is provided in the placement groove. A sealing film is provided at the bottom of the placement groove. The bottom surface of the clamping wall is connected to the disinfection cover. The disinfection cover is provided with an alcohol chamber.
