Conventional Micro Needle does not have a hollow. A hollow in our Hollow Micro Needle (HMN) is made by specific laser technology. HMN with a diameter of 100-µm, the length of 800-µｍ, and a hollow diameter of 30 µm has been successfully developed.
This HMN provides two features. 100-µm outer diameter of our HMN is as small as that of mosquito and patients feel no pain. Our HMN made from PGA is harmless to the human body.
Even in case, the HMN is snapped off, it is absorbed into the skin. Our HMN technology creates Insulin Injector with a new HMN cap and patch type intradermal HMN sheet.
