Problems solved by technology

[0002] Clinically, some special patients, such as diabetic patients, hepatitis patients, etc., need to inject insulin, interferon, growth hormone, vaccines, etc. on different occasions by themselves, and the accuracy of the injection dosage is particularly high. It is necessary to extract the liquid medicine first, which is inconvenient to operate and carry, and cannot effectively achieve accurate medication
There are also some liquid medicine injection pens in the prior art, which can be injected accurately, and can store the liquid medicine in the injection pen, which is easy to carry, but most of these liquid medicine injection pens can only be used once, and it is difficult to restore the original state after use reuse
