1. A syringe body and needle assembly, comprising:
a syringe body having a nozzle that has an opening; a needle fixed in the syringe body or in the nozzle of the syringe body, and the opening of the nozzle through which the needle is introduced into an interior of the syringe body is hermetically sealed to the needle; and a connecting body comprising a first material provided in a region of the nozzle and the connecting body, the first material absorbing more electromagnetic radiation within a wavelength range than a second material from which the syringe body is made of, wherein the needle is fused into the first material which absorbs more electromagnetic radiation, wherein, in the wavelength range of the electromagnetic radiation, the first material in the region of the nozzle has a total energy absorption in a single pass of the radiation that is at least 10% higher than that of the second material of the syringe body, and wherein the connecting body comprises doped glass. |
