Characteristics and application of injection pen products

Pen-type syringe, referred to as injection pen, is a product that combines medicine and syringe. It is shaped like a pen and mainly consists of a pen cap, a pen refill, an injection cylinder and a needle. Drugs are stored in the pen refill, which is generally used in combination with specific injection pens. Pen refills from different manufacturers are not compatible. When using, remove the cap, install the injection needle to exhaust gas, adjust the required dose and drive the injection button to realize and complete drug delivery.

Injection pens generally have the following characteristics:

1) Self-injection is simple, convenient and safe;

2) Reduce drug waste with adjustable dosage;

3) Automatically return to zero after injection (set the prompt tone of return to zero);

4) The scale window is enlarged, the injection resistance is reduced, the pain is relieved, and the user experience is improved.

The use of injection pens not only enhances the dependence of patients and reduces the economic burden, but also relieves the social pressure of "fewer doctors and more patients".

The pen is widely used for self-management of various chronic diseases, including insulin for diabetes, growth hormone, osteoporosis, multiple sclerosis, anemia, and rheumatoid arthritis.
