Abstract
A urinary catheter package with a case having a hollow tube which is closed at one end and open at the other end, the hollow tube having a wall and a pierceable cover attached to the open end of the hollow tube. Also an assembly including the urinary catheter package and a catheter with a funnel at a first end.
Core Innovation
The invention relates to an improved urinary catheter package that includes a case having a hollow tube closed at one end and open at the other end, where the hollow tube has a wall of unitary construction with an outer surface. The wall includes a thinned wall portion of reduced thickness on the outer surface, and a pierceable cover is attached to the open end of the hollow tube so the package can be reclosed and maintain the integrity of the sealing arrangement during handling and compression forces.
The described package embodiments further include a hinged cap arranged to move between open and closed positions for catheter access and reclosure. Sealing is addressed using a dynamic seal and seal ring arrangements, including cap/shoulder sealing surfaces with a seal ring and a soft dome bell or soft liner for sealing against a ferrule.
Additional embodiments describe anti-dislodgement and latching features and corresponding engagement structures that resist movement under side loads and help maintain attachment relationships during compression. Examples include tab-and-detent into a depression, tongue/groove engagement, rail-and-locking slide retention, a bead-in-groove arrangement, skirt and seal liner engagement into a ferrule gap, and a locking arm with a detent.
Claims Coverage
The provided claim set includes two independent claims. Both independent claims center on a urinary catheter package or catheter assembly with a case structure and a pierceable cover, characterized primarily by a unitary tube wall having a thinned wall portion of reduced thickness and the attachment of a pierceable cover to the open end; the second independent claim adds a urinary catheter having a funnel at a first end.
Thinned wall portion of reduced thickness in a unitary case tube wall
A case having a hollow tube closed at one end and open at the other end, wherein the hollow tube has a wall of unitary construction with an outer surface and the wall includes a thinned wall portion of reduced thickness in the outer surface of the wall.
Pierceable cover attached to the open end of the hollow tube
A pierceable cover attached to the open end of the hollow tube.
Funnel at a first end of the urinary catheter
A urinary catheter includes a funnel at a first end.
Across the independent claims, the core structural inventive features are the unitary case tube wall with a thinned wall portion of reduced thickness and the pierceable cover attached to the open end; in the assembly claim, the packaged urinary catheter further includes a urinary catheter having a funnel at a first end.
