Abstract An assembly of elements installed in the funnel of a catheter including a piece of rubber tubing having a diameter large enough to bear against the inner wall of the funnel in combination with a relatively stiff plastic valve liner of approximately conical form when closed, split longitudinally from its apex to points near its base, the valve liner resting in the funnel entrance beside an outer flattened end of the rubber tubing, the inner end portion of the tubing bearing against the funnel wall and closing the funnel; the plastic valve liner being adapted to receive the tapered end of connector or adapter which separates the split portions of the valve and pushes aside the funnel-closing portion of the tubing.
A catheter-coupling assembly in combination with the funnel of a catheter comprising: a section of rubberlike tubing having a diameter equal to that of the funnel lumen, a length less than the length of the funnel, and being installed midway therein and a valve liner element having an open end adjacent the open end of the funnel and separable parts extending into the funnel, one of said parts resting against one side of the tubing section, the end of the tubing adjacent said valve-liner element being flattened between said element and the wall of the funnel.

A catheter-coupling assembly in combination with the funnel of a catheter comprising: a section of rubberlike tubing having a diameter equal to that of the funnel lumen, a length less than the length of the funnel, and being installed midway therein and a valve liner element having an open end adjacent the open end of the funnel and separable parts extending into the funnel, one of said parts resting against one side of the tubing section, the end of the tubing adjacent said valve-liner element being flattened between said element and the wall of the funnel.
Claim 3
Dependent Claim
18 words
A catheter-coupling assembly according to claim 1 in which the valve liner has a relatively hard inner surface.
Claim 4
Dependent Claim
20 words
A catheter-coupling assembly according to claim 1 in which the valve liner is of a relatively still bendable plastic material.
Claim 5
Dependent Claim
32 words
A catheter-coupling assembly according to claim 1 in which the valve liner is substantially conical and is split axially from its apex to points adjacent it base to form said separable parts.
Claim 6
Dependent Claim
20 words
A catheter-coupling assembly according to claim 1 in which the end of the tubing opposite the flattened end is closed.
