Description

technical field [0001] The present invention relates to injection needles, especially for injecting medicines into human or animal bodies. The invention also relates to an injection device comprising an injection needle. Background technique [0002] Needles, for example hollow needles or injection needles, are used for subcutaneous and / or intravenous dosing by means of the dosing system, through which in particular liquids, for example medicines, can be injected into the body. Conventional hollow needles here are made of metal and are therefore only conditionally suitable for permanent use in body tissue. They are mostly used for intravenous medicaments, but not for dosing into subcutaneous fat tissue. Furthermore, these metal needles are particularly suitable for locations where the tissue does not move, stretch or compress excessively, eg the arm. Furthermore, such needles can only be used conditionally for a prolonged period, that is to say hours or days inside the bo...
