Problems solved by technology

Before use, you need to remove the protective shell to expose the needle body; after use, because the needle body is completely exposed to the outside and there is no safety protection structure, it is easy to cause accidental injury to others, and it is also easy to cause accidental injury due to accidental contact with the needle body. Circumstances leading to cross-infection
At the same time, since there is no necessary protective structure, the injection needle can be used again after use, so there is a risk of being reused

Abstract

The present invention discloses a safe and adjustable insulin syringe needle. The safe and adjustable insulin syringe needle comprises an inner shell, a protective sleeve, a locking ring, a spring, aneedle body, a needle seat and a depth adjusting sleeve, and the inner shell is provided with track changing devices, external threads, a first elastic arm and an adjusting lug; the depth adjusting sleeve is provided with internal threads and adjusting grooves; the protective sleeve is provided with guide lugs, downward pressing lugs and downward pressing inclined planes; the locking ring is provided with through grooves, elastic arms and positioning baffle blocks; and the positioning baffle blocks are provided with second sliding inclined planes and transition inclined planes. Before injection, the safe and adjustable insulin syringe needle can adjust gears to control injection depth according to individual conditions of patients so as to meet injection requirements of different people; and in addition, after the injection is completed, the needle can be automatically hidden, is not exposed due to mistaken touch, avoids causing injury to people, plays effects of avoiding cross infection, and can also be prevented from risks of being repeatedly used.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a safe and adjustable insulin injection needle. Background technique [0002] As a tool for treating diabetes, insulin injection needles have been widely used. Its main function is to control blood sugar in patients with diabetes by injecting insulin into their bodies. [0003] In the prior art insulin injection needles, the position of the injection needles is usually fixed. Due to differences in age and body shape of diabetic patients, the depth of the needle penetration into the skin needs to be adjusted accordingly during injection. Because the function of the insulin injection needle in the prior art is relatively single, the injection length of the needle cannot be adjusted, and experienced medical personnel are usually required to perform the injection, which brings certain troubles to patients when they inject themselves. [0004] In addition, the insulin injec...
