Abstract
An attachment for a syringe or carpule includes a main body that encloses an interior space, into which a protrusion of the syringe or carpule can be inserted. The main body has a jacket surrounding the interior space, and includes an inner body connected to the jacket and arranged coaxially thereto. The inner body has an inner wall that, in the attached state of the attachment, contacts an outer surface of the protrusion or of the syringe or carpule by means of an interior surface facing the interior space. The inner wall of the inner body is connected to the jacket of the attachment by a number of webs. At least one web encloses an angle together with an imaginary radially extending line, the angle being greater than 0° and acute.
Core Innovation
The invention relates to an attachment for a syringe or carpule having a main body enclosing an interior space into which a protrusion of the syringe or carpule can be inserted. The main body includes a jacket surrounding the interior space, and an inner body connected to the jacket and arranged coaxially thereto, with an inner wall that contacts an outer surface of the protrusion in an attached state by an interior surface facing the interior space.
The inner wall of the inner body is connected to the jacket by a number of pivotably connected webs. At least one web encloses an acute angle together with an imaginary radially extending line, and the web extends radially and is compressed between the jacket and the inner wall in response to a rotational torque, while an open space is enclosed between two adjacent webs and the jacket and the inner wall bound the open space.
In embodiments, the inner body is formed as a continuous inner wall or as ring segments, and abutments positioned relative to open spaces and webs limit web pivoting into a radial, compressed position and secure against rotation in one or both directions. The function is based on frictional gripping by the interior surface and, optionally, by snapping into an annular groove, with soft inner surface material described for increasing friction.
Claims Coverage
The document contains two independent claims. Both claims focus on a coaxial syringe/carpule attachment with pivotable, radially extending webs that compress between a jacket and an inner wall in response to rotational torque, enclosing open spaces between adjacent webs.
Coaxial jacket and inner body forming an interior gripping interface
A main body enclosing an interior space with a jacket surrounding the interior space, and an inner body connected to the jacket and arranged coaxially thereto, wherein an inner wall contacts an outer surface of a syringe or carpule protrusion in an attached state by an interior surface facing the interior space.
Pivotably connected radially extending webs compressible by rotational torque
The inner wall of the inner body is connected to the jacket by a number of webs, wherein at least one web is pivotably connected to the inner wall and to the jacket such that the at least one web extends radially and is compressed between the jacket and the inner wall of the inner body in response to a rotational torque.
Acute angled web geometry relative to an imaginary radially extending line
At least one web encloses an angle together with an imaginary radially extending line, the angle being greater than 0° and acute.
Open spaces enclosed between adjacent webs
An open space is enclosed between two adjacent webs, the jacket and the inner wall of the inner body.
Web sides defined by first and second parallel sides
The at least one web includes first and second parallel sides extending from the inner body to the jacket.
Across both independent claims, the core claimed coverage is the coaxial attachment structure with an inner wall facing the interior space, multiple pivotably connected webs linking the jacket to the inner wall, web compression or compressibility caused by rotational torque, and open spaces enclosed between adjacent webs, with one independent claim additionally requiring acute-angle geometry and the other requiring first and second parallel sides of a web.
