Abstract
An attachment for a syringe, carpule, or the like, includes a distal end and a terminal extension with an outer surface, a free end, and a depression introduced at a spacing into the outer surface. The attachment includes an annular base body and is placeable onto the extension. The base body encloses a free space into which the extension is introducible. The base body contains two materials a first material which is dimensionally stable and a second material which is softer than the first material and deformable. The base body has an engagement region, which engages into the depression. The extension is thus characterized in that the base body has, along an imaginary circumferential line, a first region with the first material and a second region containing the second material. The second material deforms into the depression in a placed-onto-the-extension state. The second material is embedded into the first material.
Core Innovation
An attachment for a syringe or a carpule includes a distal end and a terminal extension having an outer surface, a free end, and at least one depression introduced into the outer surface at a distance to the free end. The attachment is placeable onto the terminal extension and comprises an annular base body enclosing a free space into which the terminal extension is introduced, the annular base body being composed of a dimensionally stable first material and a softer second material that is deformable.
The annular base body includes at least one engagement region which, when the annular base body is plugged onto the terminal extension, engages into the at least one depression. Along an imaginary circumferential line, the annular base body has first regions including the first material and second regions including the second material, and in the plugged state the second material is molded into the at least one depression and is embedded into the first material.
On a first end, the annular base body includes an annular body which, when applied to the terminal extension, embraces an annular region of the terminal extension. The at least one depression is disposed in the annular region, and the annular body includes segments which form the first regions and laterally adjacent openings in intermediate spaces between the segments in which the second material is arranged to form the second regions.
Claims Coverage
The document provides one independent claim. The inventive coverage is characterized by an annular two-material base body that is plugged onto a terminal extension so that a softer second material is molded into a depression and embedded within a dimensionally stable first material along an imaginary circumferential line, with an annular body embracing an annular region of the extension containing the depression.
Plug-on annular base body with dimensionally stable first material and deformable second material molded into a depression
An attachment for a syringe or a carpule placeable onto a terminal extension, comprising an annular base body enclosing a free space, the annular base body being composed of a dimensionally stable first material and a softer deformable second material, including at least one engagement region that engages into at least one depression of the terminal extension, wherein along an imaginary circumferential line the annular base body has first regions of the first material and second regions of the second material, and in the plugged state the second material is molded into the at least one depression and is embedded into the first material, with an annular body embracing an annular region of the terminal extension.
Segments and laterally adjacent openings defining first and second regions along an imaginary circumferential line
The annular body includes segments forming the first regions and laterally adjacent openings in intermediate spaces between the segments, in which the second material is arranged to form the second regions, with the imaginary circumferential line located in the region of the at least one depression when the annular body is applied.
Across the independent claim, protection centers on a two-material annular attachment that plugs onto a syringe or carpule terminal extension and uses engagement of a molded-in, embedded second material within a depression of the extension, with material region distribution along an imaginary circumferential line using segments and laterally adjacent openings.
Stated Advantages
Prevents axial pulling-off.
Prevents undesired rotation (torque) during use and sterilization.
Documented Applications
Attachment for a syringe or a carpule terminal extension, including during use and sterilization.
