摘要

The utility model relates to medicine, namely to medical instruments, and can be used for independent subcutaneous injections of solutions of medicinal substances, for example, insulin in the treatment of diabetes mellitus. The technical goal is to provide increased strength and safety of the catheter when used, simplifying the manufacture of a cutaneous device, elimination of import dependence on component parts. The goal is achieved through the use of a skin device of the system for multiple ozhnogo administration of drug solution, comprising a syringe body in which an upper piston with the needle and handle, with the lower piston mounted therein subcutaneous catheter, and a protective lid connected by a connecting catheter with a port for feeding the solution. In this case, the lower piston with a subcutaneous catheter is made in a single body of a biologically inert material, forming a common channel.
