Abstract

A catheter package includes an elongated case. A cap is attached to the case by a flexible strap. The case receives the tubing portion of a catheter. The catheter has a funnel attached to the tubing. The funnel has a seal portion releasably engageable with the case. The cap is releasably engageable with the funnel to retain the funnel in contact with the case. A user can flip the cap off the funnel to permit removal of the catheter from the case. The funnel may include ridges or a tactile ring to improve the user's grip on the funnel. An adaptor may be disposed between the funnel and case to allow mating of different cross sectional shapes of the funnel and case. A hydration device may be inserted in the case. Alternately, a tubular liner may be inserted in the case to separate liquid water on the outside of the liner from the catheter tubing on the inside of the liner. A window in the liner mounts a patch of filter material that permits the passage of water vapor into the interior of the liner.

Claims (25)

1 . A catheter, comprising:

an elongated tubing and a funnel attached to one end of the elongated tubing, the funnel having a body portion; and

a plurality of ridges formed on an exterior surface of the body portion and protruding upwardly from said exterior surface; and

a tactile ring formed near an end of the body portion that receives the elongated tubing and protruding upwardly from the exterior surface, wherein the tactile ring comprises a portion of increased exterior dimension compared to the body portion.

2 . The catheter of claim 1 , wherein the plurality of ridges comprises ridges that are connected in a spiral shape.

3 . The catheter of claim 1 , wherein the plurality of ridges comprises ridges which are individual rings.

4 . The catheter of claim 1 , wherein the plurality of ridges comprises ridges that have a variable helix angle from a first end of the body portion of the funnel to a second end of the body portion of the funnel.

5 . The catheter of claim 1 , wherein the plurality of ridges and the funnel are comprised of the same material.

6 . The catheter of claim 1 , wherein the plurality of ridges and the funnel are comprised of different materials.

7 . The catheter of claim 1 , wherein the plurality of ridges and the funnel are different stiffnesses.

8 . The catheter of claim 1 further comprising a second tactile ring formed near a second end of the body portion and protruding upwardly from the exterior surface.

9 . A catheter, comprising:

an elongated tubing and a funnel attached to one end of the elongated tubing, the funnel having a body portion; and

a tactile ring formed on an exterior surface of the body portion and protruding upwardly from said exterior surface, the tactile ring being axially located near an end of the body portion that receives the elongated tubing and protruding upwardly from the exterior surface, wherein the tactile ring comprises a portion of increased exterior dimension compared to the body portion.

10 . The catheter of claim 9 , wherein the body portion includes at least two tactile rings.

11 . The catheter of claim 10 , wherein the at least two tactile rings includes a tactile ring located at a first end of the body portion and a tactile ring located at a second end of the body portion.

12 . The catheter of claim 9 , wherein the tactile ring includes a smooth surface.

13 . The catheter of claim 9 , wherein the body portion includes a plurality of ridges.

14 . The catheter of claim 13 , wherein the at least one tactile ring has a slightly larger external dimension compared to the plurality of ridges.

15 . The catheter of claim 9 further comprising a second tactile ring formed near a second end of the body portion and protruding upwardly from the exterior surface.

16 . A catheter comprising an elongated tubing attached to a hollow funnel that has a wall, the wall defining a longitudinal axis and having an internal surface defining a lumen and external surfaces, the wall further including first and second ends, the funnel being integrally attached to the elongated tubing and having a first cross section intermediate the ends wherein the internal surface and the external surface of the cross section are circular, the funnel further including a second cross section near one of the ends wherein the internal surface is circular and the external surfaces have at least one pair of parallel straight portions to define a non-circular external cross section.

17 . The catheter of claim 16 wherein the external surfaces have four straight portions joined by arcuate corner portions.

18 . The catheter of claim 16 wherein the external surfaces include a plurality of ridges formed thereon and protruding upwardly from said surfaces.

19 . The catheter of claim 16 wherein the external surfaces include at least one tactile ring formed thereon and protruding upwardly from said surfaces.

20 . The catheter of claim 16 wherein the external surfaces include a plurality of ridges formed thereon and protruding upwardly from said surfaces and wherein the external surfaces further include at least one tactile ring formed thereon and protruding upwardly from said surfaces.
