Abstract
An insert (100) for a patient fluid discharge tube (A) facilitates removal of the discharge tube from the patient, wherein the insert provides a smooth outer surface (12a) and also an arrangement (20) for aiding in attaching a removal tool to the insert such that the end of the discharge tube may be easily grasped and pulled from the patient.
Claims16
A drainage tube assembly for at least partial insertion into a patient's body comprising:
- a drainage tube having an end for insertion into and removal from said body;
- and
- a gripping tool affixed to said drainage tube and arranged to be gripped with a removal member for pulling the end of said drainage tube remaining in a patient's body out of the body comprising:
- a main body configured for attachment to the distal end of said drainage tube and having a through channel;
- a gripping part configured to be gripped by said removal member, the gripping part including multiple projecting parts spaced longitudinally from each other;
- and
- a bendable connecting part that connects said main body and said gripping part, the connecting part disposed within said through channel and protruding proximally from said through channel;
- the main body, gripping part and connecting part of the tool each being separate from said drainage tube.
A discharge tube assembly for at least partial insertion into a patient's body comprising:
- a discharge tube having an end for insertion into and removal from said body;
- and
- a gripping tool separate from the discharge tube, the gripping tool including a main body inserted in the end of the discharge tube, said main body having:
- a first end region inserted in said discharge tube end,
- a second end region protruding distally from said discharge tube end,
- a through channel connecting said first and second end regions,
- a connecting part disposed within said through channel and protruding proximally from said through channel away from the first end region;
- and
- a gripping element protruding distally away from said second end region including surface gripping protrusions spaced longitudinally from each other for gripping by a removal tool in a removal operation;
- and
- a stop for preventing pull-through of said connecting part through said through channel out of the second end region.
In combination, a drainage tube and a gripping tool for attachment to a distal end of a flexible drainage tube used for discharging fluids in the body, the gripping tool being arranged to be gripped with a removal member for pulling the end of said drainage tube remaining in a patient's body out of the body, the gripping tool comprising:
- a main body configured for attachment to the distal end of said drainage tube, the main body having a narrow proximal portion and a wide distal portion, the narrow proximal portion configured for insertion into the distal end of the drainage tube to engage an inner surface of the drainage tube to hold the tool in the drainage tube, said body having a through channel;
- a gripping part that is to be gripped by said removal member and includes multiple projecting parts spaced longitudinally from each other;
- and
- a connecting part that can bend and which connects said main body and said gripping part, the connecting part disposed within said through channel and protruding proximally from said through channel;
- the main body, gripping part and connecting part of the tool each being separate from said drainage tube.
