With the development of society, people's living habits change, work pressure is too big, the change of diet structure, more and more people change to diabetes. All kinds of traditional methods and means of reducing sugar have been unable to meet the requirements of the patients. With the development of science and technology, people begin to accept the simple and effective method of insulin pen injection.
The insulin injection pen is a new type of insulin injector, which is hand-held and external to the stomach. It is suitable for diabetics to give self subcutaneous injection. Insulin pen is mainly composed of a pen cap, pen rack (bottle holder), pen body composition. The insulin injection pen stores the insulin in a specially designed device, which is effectively stored in the pen core, and the pen core is replaced only after the use of insulin. The pen is an adjustable dose of the syringe, with a specially designed ultra - fine, ultra short needle. When a patient is used, he only needs to adjust the injection dose to the required dose unit, then stab the needle into the subcutaneous tissue, and press the injection button on the injection pen, so that the whole injection process can be easily completed.
Since the insulin drug was successfully separated in 1921 and used to treat diabetes, its injection device has been constantly developing and innovating. Injection of syringes, insulin high pressure syringe, insulin pump, and insulin injection pen are the "four Trilogy" in the development history of insulin injection device. Among them, the syringe is a traditional insulin injection device, and it is still widely used in some places. The advantage of low price is its advantage, but because it is not designed for diabetic patients, its disadvantages are also obvious. For example, higher injection skills can not achieve accurate injection, and it is not convenient to carry out the door and cause pain when injected. Insulin is not necessary for high pressure syringe needle, but high pressure air will bring damage the skin. The delivery pipe of the insulin pump is easily blocked. Insulin pens although history is not long, but because the medical device is specially designed according to the actual needs of diabetic patients, the drug and injection device skillfully combined, easy and safe, and quickly becomes the current widespread use of insulin injection device.
The insulin injection pen is mainly a durable and durable injection pen. With the in-depth study of the injection device, the accuracy of the injection of the insulin pen and the simplicity of the operation have been broken through. This new type of insulin pen than the previous product, the thing is to hold the pen body with a dose adjustment; windows more, reading more clear; the required injection thrust is reduced by half, the piston rod can be directly pushed back, can be a simple dose injection have two-way adjustment; "clicking" tone, to remind patients have injection after. In addition, it can measure the residual dose in the pen core, which ensures the accuracy of the replacement of the pen core.
The insulin injection pen should be properly preserved and special for one person. No matter whether it is open or not, the insulin drugs are suitable for storage in the refrigerator room of 2 C-8 C, which can not be exposed to the sun or in the refrigerator freezer. Before injection, it is necessary to remove insulin and put it to room temperature. If it is just taken out of the refrigerator and injected, it can stimulate the injection site because of the low temperature.
