摘要 |
The present invention relates to improvements on automatic injection devices, in particular for self-administered drug therapies, providing for a high degree of internal stability of the syringe and, therefore, of the associated needle, thanks to a series of elastic wasp-waisted elements and a mobile tip made of a transparent material in the preferred embodiment, which besides enabling the regulation of the length of projection of the needle during the injection also allows the user to see the exact spot where the needle will enter the flesh.
