Current status of the development of injection pens:

Injection pen compared to the traditional syringe injection method has a simple, convenient, accurate dosage, light pain and many other advantages, its injection method in line with the needs of self-management in the field of chronic disease development, since the birth of the injection pen, the pharmaceutical giants and design companies have been committed to the research of the drug self-injection device, innovation on the basis of the first-generation injection pens, has developed a series of new products.The improvement and optimization of the injection pen is mainly reflected in the refill compartment and the injection adjustment mechanism: the refill compartment improvement direction is to make the refill replacement more convenient, the drug storage and release more convenient; the improvement direction of the adjustment mechanism is embodied in the improvement of the injection precision, simplify the structure, and convenient for the patient's operation, all the improvement of the nature of the purpose is to make the patient's operation more simple, to avoid the adverse effects of misoperation and to improve the user experience.

At present, the existing injection pen products on the market can be categorized in two ways, according to whether the drug can be replaced is divided into repeatable injection pens and disposable injection pens; according to its structural principle (energy transfer method) is different, is divided into mechanical injection pens and electronic smart injection pens.

In the first classification, the repeatable injection pen body and the drug compartment are generally connected by thread or snap, after the use of drugs can be replaced with a new refill for repeated use, but before replacing the refill needs to be pushed back to realize the reuse, so its structural design is more complex than the disposable injection pens, the number of parts is higher, the assembly is complicated, and the parts are rigorously coordinated in order to realize the accurate transmission relationship. Disposable injection pen is a “drug and device in one” product, the pen body and the drug compartment into one non-detachable, but the structure and function can be designed in accordance with the characteristics of the filled drugs, the method of use and the injection dosage, to realize the customization of innovative products, and has been developed out of the adjustable, quantitative and lyophilized drugs, such as pre-mixed injection pen and other types of The development prospect of disposable injection pens is worth looking forward to.

In the second classification, mechanical injection pen is the first technical principle adopted in the field of injection pens, and in view of the fact that the technology in this field has tended to be stabilized, the injection pen products of this type of technology have gradually taken the leading position in the market, such as Novo's development of Novo's 1 to 5 generations of products, Eli Lilly's U-Pen series of injection pens, as well as Sungi Pharmaceuticals in recent years to develop the Type II adjustable injection pens and the micro-adjustable injection pens that are under development. Adjustable injection pens belong to the representative products of mechanical injection pens; electronic smart injection pen is a new type of product that adopts the principle of motor drive to realize the same function as mechanical injection pens, and its one-touch button operation realizes the characteristics of dosage setting and automatic injection to make the injection process easier.

The future and development of injection pens:

Injection device history to date, large foreign pharmaceutical companies have been listed on various types of products through artificial factors engineering and global sharing, research on the interaction between the product, the user and the environment, the results proved that chronic disease self-management equipment in the operation of the ease of patients to consider the primary issue of injection pen in line with the needs of the patient's operating technology in the medical field will gain more and more attention and use. At present, foreign injection pen technology has been developed by the mature mechanical technology transition to intelligent injection technology stage, while the domestic involved in the field of injection pens but only a few companies, so as one of the few domestic independent research and development of injection pen products, we need to comply with the country's specific regulatory requirements under the premise of further adapting to the global design and control process in the development of collaborative design of the product in the development of the commercialization model of the road! We are striving to realize the goal of “replacing imported products with domestic ones”, and taking a step forward to realize a high-tech enterprise.
