Abstract

Device for sealing an opening to a body cavity while providing for the introduction of fluid to or extraction of fluid from said cavity comprising a primary sealing member slidably mounted on a catheter type flexible tube, the latter providing means for passage of fluid to and/or from said body, and a secondary sealing member also slidably mounted on said tube. In preferred embodiments the secondary sealing member includes a porous or foamed material adherent to form an absorbent interference seal about the tube and preclude the passage of fluid which might accidentally pass along the tube from the primary sealing member. In certain embodiments segments of pressure sensitive tape are also mounted about the tube to provide means for positively attaching at least the primary sealing member to the body to which it is applied.

Claims

1. Apparatus for use in delivering fluid to and/or from a body cavity while maintaining a seal thereof comprising a catheter type tube, one end of which is adapted for insertion through an opening to said cavity, a first sealing member mounting on said tube, and a second sealing member mounting on said tube in following relation to the first said member, said sealing members being adjustable in a sense longitudinally of the tube following insertion of said tube end, to seal the opening to said body cavity about said tube, the first sealing member being contoured to enter said opening to bridge and form a seal between the outer surface of said tube and the edge of the body opening, the second said sealing member having a transverse dimension greater than that of the first and serving as a back-up for the first and including in connection therewith, a moisture absorbing medium.

2. Apparatus as in claim 1 characterized by said second sealing member being arranged to trap fluid which might by-pass said first member by seeping outwardly of said body cavity along the surface of said tube.

3. Apparatus as in claim 1 characterized by said first sealing member having a nipple-like configuration and a central aperture accommodating said tube, the base of said nipple-like member being formed to overlap the edges of the opening to said cavity as the head thereof is slid in to said opening to bridge the same about said tube.

4. Apparatus as in claim 1 characterized by said second sealing member including moisture absorbent pad means peripherally surrounding said tube behind said first sealing member.

5. Apparatus as in claim 4 characterized by an impermeable envelope about said moisture absorbent pad means except in the area thereof immediately about said tube means.

6. Apparatus for use in delivering fluid to and/or from a body cavity while maintaining a seal thereof comprising a catheter type tube, one end of which is adapted for insertion through an opening to said cavity, a first sealing member mounting on said tube, and a second sealing member mounted on said tube in following relation to the first said member, said second sealing member including a moisture absorbent pad means peripherally surrounding said tube behind said first sealing member and an impermeable envelope about said moisture absorbent pad means except in the area thereof immediately about said tube, said sealing members being adjustable in a sense longitudinally of said tube to seal the opening to said body cavity about said tube, the second said sealing member serving as a back-up for the first, and retention means associated with at least said first sealing member for releasably fixing the same in its sealing relation to the opening to the body cavity.

7. Apparatus as in claim 6 characterized by said retention means being embodied in means slidable on said tube means.

8. Apparatus for use in delivering fluid to and/or from a body cavity through a surgically formed body opening, including a soft flexible catheter type tube an end of which is insertable in said cavity through said opening and said tube having a relatively small uniform diameter to be substantially unlimited and unobstructed in its movement into and out of said body cavity, and a sealing member on said tube having a nipple-like portion on one end and flaring therefrom to an expanded flange-like base portion, said sealing member being made of a soft pliable material and sealingly engaging around said tube, said sealing member being slidably mounted on said tube end whereby in the use of the apparatus said tube end may be inserted a selected distance into said body cavity and said sealing member then slid along said tube toward said tube end until said nipple-like portion of said member is received in said opening and said expanded flange-like base portion seats to the body around said opening and adhesive retention means slidable on said tube inwardly of said sealing member and having a transverse dimension to exceed that of said base portion of said sealing member, saiD retention means being advanceable outwardly upon a seated sealing member to make adherent contact with the body around said member.

9. Apparatus according to claim 8 characterized by a resilient deformable means slidably mounted on said tube inwardly of said adhesive retention means and adjustable thereon outwardly into a backing relation to a seated assembly comprising said sealing member and said adhesive retention means.
