Claims
- 1. An oxygen-suction catheter assembly including
- a first hollow tubular portion comprising a front chamber for insertion into the mouth of a patient,
- a second hollow tubular portion coupled to said first tubular portion and comprising a rear chamber for coupling patient treatment means into said first tubular portion and into a patient,
- a third tubular portion coupled to said first tubular portion,
- flexible tube means slidably coupled to said second hollow tubular portion for insertion through said second hollow tubular portion and said first hollow tubular portion into a patient,
- a wall between said second tubular portion and said first tubular portion and having an aperture for permitting said flexible tube means to pass therethrough,
- means adjacent to said wall for blocking and blocking said aperture,
- said blocking and unblocking means having a first unblocked position when said flexible tube means is inserted through said aperture and into a patient and a second blocked position when said flexible tube means is withdrawn from a patient into said rear chamber, and
- cleaning means in said rear chamber for cleaning said flexible tube means as it is withdrawn from a patient.
- 2. The apparatus defined in claim 1 wherein said cleaning means is a sponge which has a through hole through which flexible tube means is slid.
- 3. The apparatus defined in claim 2 wherein said through-hole has a cross-sectional shape comparable to the cross-sectional shape of said flexible tube.
- 4. The apparatus defined in claim 1 and including a sleeve positioned between said wall and said cleaning means, said cleaning means comprising a sponge.
- 5. The apparatus defined in claim 1 wherein said blocking and unblocking means comprising a slidable solid plate having an aperture, said solid plate being slid from a first position in which said plate aperture is in alignment with said wall aperture, and a second position in which said plate aperture is out of alignment with said wall aperture.
- 6. The apparatus defined in claim 1 wherein said first, second and third tubular portions form a T-shaped structure and said first and second portions are generally horizontal and aligned with each other and said third portion extends at an angle to said first and second portions.
- 7. The apparatus defined in claim 1 wherein said second tubular portion has an open end remote from said wall and including a removable cap coupled to said open end of said second tubular portion.
- 8. The apparatus defined in claim 1 and including first and second tubes secured to said rear chamber and accessible outside said rear chamber whereby said first tube can be connected to a source of suction and said second tube can be open as a vent.
- 9. The apparatus defined in claim 1 wherein said flexible tube means has a patient end which is inserted into said first tubular portion and a remote end,
- a valve secured to said remote end of said flexible tube means,
- said valve including a first inlet pipe for receiving oxygen and a first outlet pipe for receiving oxygen from said first inlet pipe and coupled to said flexible tube means, said valve also including a second inlet pipe for receiving suction and a second outlet pipe for receiving suction from said second inlet pipe and coupled to said flexible tube means,
- holes in said valve for venting suction and oxygen to air when one or the other is not connected to said first or second outlet pipes, and
- auxiliary means in said valve for blocking said first outlet pipe when said second outlet pipe is receiving suction and for blocking said second outlet pipe when said first outlet pipe is receiving oxygen whereby a patient will not lose oxygen during a suctioning operation.
- 10. The apparatus defined in claim 9 and including a protective sleeve secured between said second tubular portion and said valve and enclosing said flexible tube means.
- 11. The apparatus defined in claim 1 and including securing means coupled between said rear chamber and said flexible tube means whereby said flexible tube means is prevented from being removed from said rear chamber.
- 12. A catheter assembly comprising:
- a hollow T-shaped member including a cross member and an arm extending therefrom, said cross member having a front end adapted to be inserted into a patient and a rear end,
- a wall extending across said cross member and closing off said rear end of said connector from said arm and said front end of said connector,
- means operable by an operator to open said wall, and
- second means in said rear end of said cross member for permitting a portion of a catheter to pass therethrough and to be cleaned thereby.
- 13. The apparatus defined in claim 12 wherein said second means is a sponge.
- 14. The apparatus defined in claim 13 wherein said sponge has means for permitting a catheter to pass through it.
- 15. The apparatus defined in claim 12 wherein said means comprises a plate in said wall adapted to be moved to provide an opening in said wall.
- 16. The apparatus defined in claim 12 wherein said means is a slide in said wall adapted to be moved to provide an opening in said wall.
