FIELD: medicine.
SUBSTANCE: end protrusion has an outer surface, a free end and at least one recess introduced into the outer surface at a distance therefrom. Wherein the attachment has an annular main body and can be placed on the protrusion. Wherein the main body encloses a free space into which the protrusion can be introduced. Wherein the main body comprises two materials, of which a first material is dimensionally stable and a second material is softer than the dimensionally stable first material and deformable. Wherein the main body has at least one engagement region which engages with the at least one recess when positioned on the protrusion. And along an imaginary circumferential line, the main body has first regions with the first material and second regions with the second material. Wherein the second material is deformed into the at least one recess when attached to the protrusion. Wherein the second material is embedded into the first material. Main body has an annular body at the end, wherein the annular body encloses an annular region of the protrusion, when placed on the protrusion, wherein in said region of the protrusion there is at least one recess. Annular body has, in a circumferential direction, along said imaginary circumferential line, segments forming said first regions, and, in the intermediate spaces between the segments, has recesses receiving the second material and forming said second regions. Wherein said imaginary circumferential line is in a region of said at least one recess of the protrusion, when placed on the protrusion.
EFFECT: invention relates to medical equipment, namely to an attachment for a syringe or carpule having a distal end and an end protrusion thereon.
