Abstract
Abstract There is disclosed an apparatus for the sanitary removal of an indwelling tube from an implantation site in a patient, comprising a tube adapter that is connectable to the indwelling tube. An impervious sleeve is fan-folded into a hub which extends around the tube adapter. In assembly the folded sleeve is retained by a shrink-wrapped plastic film. The sleeve can be extended for receiving the indwelling tube therethrough and to encompass the implantation site. The indwelling tube and the implantation site are isolated from the environment when the distal open end of the sleeve is extended and applied about the implantation site and the indwelling tube is withdrawn into the sleeve. A drawstring is provided for closing the distal end of the sleeve after the tube has been withdrawn. Embodiments are shown for removing a plurality of indwelling tubes in one operation, and for maintaining the lumen of the indwelling tube under suction or in connection with a drain during the removal operation.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
140 words
An apparatus for the sanitary removal of an indwelling tube from an implantation site in a patient while isolating the tube and the implantation site from an environment thereabout, comprising: a tube adapter having a distal end that is connectable to said indwelling tube; an extensible impervious sleeve folded around said tube adapter, said sleeve having a closed proximal end, and further having an open distal end for receiving said indwelling tube therethrough, said distal end being dimensioned to encompass said implantation site; and a hub, disposed in sealing contact about said tube adapter, said hub having means for containing said unextended sleeve; whereby said sleeve isolates said indwelling tube and said implantation site from said environment when said distal open end of said sleeve is applied about said implantation site and said indwelling tube is withdrawn into said sleeve.
Claim 2
Independent Claim
140 words
An apparatus for the sanitary removal of an indwelling tube from an implantation site in a patient while isolating the tube and the implantation site from an environment thereabout, comprising: a tube adapter having a distal end that is connectable to said indwelling tube; an extensible impervious sleeve folded around said tube adapter, said sleeve having a closed proximal end, and further having an open distal end for receiving said indwelling tube therethrough, said distal end being dimensioned to encompass said implantation site; and a hub, disposed in sealing contact about said tube adapter, said hub having means for containing said unextended sleeve; whereby said sleeve isolates said indwelling tube and said implantation site from said environment when said distal open end of said sleeve is applied about said implantation site and said indwelling tube is withdrawn into said sleeve.
Claim 3
Dependent Claim
19 words
The apparatus according to claim 1, wherein said means for containing comprises an annular recess formed in said hub.
Claim 4
Dependent Claim
24 words
The apparatus according to claim 2, wherein said sleeve is fan-folded within said annular recess, and further comprising means for retaining said sleeve therein.
Claim 5
Dependent Claim
72 words
The apparatus according to claim 3, wherein said hub further comprises an annular container for containing a portion of said folded sleeve, said annular container having a central aperture therethrough, a rim of said annular container being in opposing contact with said hub about said annular recess to encase said folded sleeve therebetween, said distal end of said sleeve being attached to said annular container for extension therewith about the indwelling tube.
Claim 6
Dependent Claim
17 words
The apparatus according to claim 1, further comprising a drainage adapter in communication with said tube adapter.
Claim 7
Dependent Claim
17 words
The apparatus according to claim 1, further comprising means for closing said distal end of said sleeve.
Claim 8
Independent Claim
160 words
An apparatus for the sanitary removal of an indwelling tube from a patient, comprising: a hub having a passage therethrough for establishing a fluid communication path between a first tube adapter and a second tube adapter, said first and second tube adapters being disposed on opposite sides of said hub, said first tube adapter being connectable to said indwelling tube, said second tube adapter being connectable to an external drainage tube; an extensible sleeve having a closed proximal portion disposed about said first tube adapter and having an open distal end for receiving said indwelling tube therethrough, said distal end being dimensioned to encompass an implantation site of said tube, said indwelling tube and said implantation site being isolated from an environment when said distal end is sealably applied about said implantation site, said hub comprising a container for said sleeve when said sleeve is unextended; whereby said isolated indwelling tube can be delivered from said patient into said sleeve.
Claim 9
Independent Claim
160 words
An apparatus for the sanitary removal of an indwelling tube from a patient, comprising: a hub having a passage therethrough for establishing a fluid communication path between a first tube adapter and a second tube adapter, said first and second tube adapters being disposed on opposite sides of said hub, said first tube adapter being connectable to said indwelling tube, said second tube adapter being connectable to an external drainage tube; an extensible sleeve having a closed proximal portion disposed about said first tube adapter and having an open distal end for receiving said indwelling tube therethrough, said distal end being dimensioned to encompass an implantation site of said tube, said indwelling tube and said implantation site being isolated from an environment when said distal end is sealably applied about said implantation site, said hub comprising a container for said sleeve when said sleeve is unextended; whereby said isolated indwelling tube can be delivered from said patient into said sleeve.
Claim 10
Dependent Claim
16 words
The apparatus according to claim 7, further comprising means for retaining said sleeve in said container.
Claim 11
Dependent Claim
15 words
The apparatus according to claim 8, wherein said means for retaining comprises a plastic film.
Claim 12
Dependent Claim
14 words
The apparatus according to claim 6, wherein said means for closing comprises a drawstring.
Claim 13
Dependent Claim
14 words
The apparatus according to claim 6, wherein said means for closing comprises a drawtape.
Claim 14
Independent Claim
171 words
A method for the sanitary removal of an indwelling tube from an implantation site in a patient while isolating the tube and the implantation site from an environment thereabout, comprising the steps of: folding an extensible impervious sleeve into a hub that surrounds a tube adapter in sealing contact therewith, said sleeve having a closed proximal end, and further having an open distal end for receiving the indwelling tube therethrough, said distal end being dimensioned to encompass the implantation site; connecting said tube adapter end to the indwelling tube; extending said sleeve about the indwelling tube into sealing contact with the patient to encompass the implantation site; and while maintaining said distal end of said sleeve in sealing contact with the patient, performing the steps of: removing said hub in a direction away from the patient to further extend said sleeve; whereby the connected indwelling tube is simultaneously withdrawn from the patient into said sleeve; and sealing said distal end of said sleeve to completely enclose the withdrawn indwelling tube therein.
Claim 15
Independent Claim
