Insulin injectors needle on the market mainly include general insulin injectors, insulin injectors and needle-free insulin injectors.
Generally, insulin injectors are designed and manufactured in accordance with the standard of one-time use. They are plastic products with exquisite workmanship, sharp needles and clear scales. In the treatment of insulin injections, you should try to ensure that you change it every time.
Insulin injection pens are divided into insulin prefilled injection pens and refillable insulin injection pens. Insulin prefilled injection pen is a one-time product, which can be thrown away together with the pen after use. Replaceable refill The body of the insulin injection pen can be reused, but the needle is disposable, and a new refill and needle need to be replaced when it is used up. Insulin injection pen can be carried with you, easy to use.
The needle-free injector uses high pressure to make insulin penetrate the surface of the skin in the form of a "liquid needle", penetrate into the subcutaneous tissue, and complete the injection with light pain and accurate dose. Since the physical needle is removed, the patient's psychological pressure and mental burden can be reduced. In addition, the needle-free injection is sprayed at a high speed in the form of a mist, and the diffusion and absorption are relatively uniform, which can prevent the occurrence of induration to a certain extent. However, the needleless injector is relatively expensive and has a high economic cost.
It should be noted that there are many varieties of insulin, and there are specially matched insulin injectors. Insulin injectors should not be used indiscriminately and must be used with matching insulin, otherwise it will simply lead to inaccurate insulin dosage and unstable blood sugar. At the same time, insulin injectors from different manufacturers cannot be used universally.
