We claim: 1. An adaptor for connecting a closed suction catheter assembly having an aspirating catheter to a heat and moisture exchanger having an aperture formed therethrough, the adaptor comprising: a first end in communication with a distal end of the closed suction catheter assembly having an aspirating catheter; a second end adapted to rotationally engage the heat and moisture exchanger having an aperture formed therethrough; and the adaptor defining a channel formed through the adaptor so that the aspirating catheter of the closed suction catheter assembly is movable through the adaptor and through the aperture of the heat and moisture exchanger. 2. The adaptor according to claim 1, wherein the second end includes an inner wall. 3. The adaptor according to claim 2, wherein the wall is configured to encircle and receive the heat and moisture exchanger. 4. The adaptor according to claim 2, wherein the wall has at least one element adapted to engage at least a portion of an exterior surface of the heat and moisture exchanger, so as to enable retention of the adaptor relative to the heat and moisture exchanger. 5. The adaptor according to claim 2, wherein the second end is adapted to threadedly engage the heat and moisture exchanger. 6. The adaptor according to claim 1, wherein the second end is a retaining ring having: a first portion and a second portion, the first and second portions oppositely disposed from each other and configured to engage the heat and moisture exchanger; and third and fourth portions being oppositely disposed from each other on the ring between the first and second portions of the ring and being responsive to inwardly applied pressure so as to cause the first and second portions to bow outwardly, thereby providing for facilitation of engagement or disengagement of the first and second portions from the heat and moisture exchanger. 7. The adaptor according to claim 6, wherein the first and second portions define apertures for receiving external projections of the heat and moisture exchanger. 8. The adaptor according to claim 1, wherein the second end comprises at least one L-shaped channel configured for receiving external projections of the heat and moisture exchanger. 9. The adaptor according to claim 1, wherein the adaptor further comprises an annular projection configured for engaging a valve in a top of the heat and moisture exchanger. 10. An adaptor assembly for connecting a closed suction catheter assembly to a heat and moisture exchanger, the adaptor assembly comprising: an adaptor comprising a first end configured for communication with a closed suction catheter assembly, and a second end configured for engaging the heat and moisture exchanger, the adaptor further comprising a retainer configured to rotationally engage the heat and moisture exchanger; an annular projection defining a channel through the adaptor through which a catheter of the closed suction catheter assembly may be advanced; and a cover removably attachable to the annular projection. 11. The adaptor assembly according to claim 10, wherein the cover has a cylindrical wall formed therein and wherein the cover further contains at least one opening formed in the cylindrical wall. 12. The adaptor of claim 10 wherein the closed suction catheter assembly comprises: an elongated catheter having a proximal and distal end; the catheter system being adapted for communication with a patient's artificial airway so as to allow the catheter to be advanced through the artificial and into the respiratory tract of the patient; a valve member comprising a flap which is pivotable between open and closed positions and which is disposed adjacent the catheter to selectively isolate the catheter from the artificial airway; and first and second wiper seals disposed for engaging the catheter as it Is retracted through the artificial airway, the first seal wiper seat being disposed distally from the second wiper seal. 13. The adaptor of claim 12, wherein the catheter is retractable so that the distal end of the catheter is disposed between the first and second wiper seals. 14. The adaptor of claim 13, further comprising a lavage port disposed for releasing cleaning fluid onto the catheter, the lavage port being disposed distally from the first wiper seal. 15. A closed suction catheter system comprising: a closed suction catheter assembly having a catheter and a protective sleeve enveloping the catheter, the closed suction catheter assembly including a distal end; and a heat and moisture exchanger adaptor disposed at the distal end of the closed suction catheter assembly, wherein the adaptor is rotationally engageable with a heat and moisture exchanger. 16. The closed suction catheter system of claim 15, wherein the adaptor comprises: a base having a first end in communication with the closed suction catheter assembly, and a second end configured for engaging the heat and moisture exchanger and positioning the closed suction catheter assembly with respect to the heat and moisture exchanger; a retaining structure configured with the base to rotationally engage the base with the heat and moisture exchanger; and a channel defined through the base so that a catheter of the closed suction catheter assembly is movable through the base and the heat and moisture exchanger and into an artificial airway connected to the heat and moisture exchanger. 17. The closed suction catheter system according to claim 16, wherein the adaptor contains an annular projection configured for engaging a valve in the proximal end of the heat and moisture exchanger. 18. The closed suction catheter system according to claim 16, wherein the retaining structure comprises a first wall and a second wall, each of the walls having an aperture capable of selectively engaging projections extending outwardly from the heat and moisture exchanger. 19. The closed suction catheter system according to claim 16, wherein the retaining structure comprises a retaining ring having at least one element adapted to engage at least a portion of the heat and moisture exchanger, so as to enable retention of the retaining structure relative to the heat and moisture exchanger. 20. The closed suction catheter system according to claim 18, wherein the heat and moisture exchanger adaptor further comprises a cover. 21. The closed suction catheter system according to claim 18, wherein the heat and moisture exchanger adaptor is releasably engaged with the distal end of the closed suction catheter assembly. 22. The closed suction catheter system according to claim 15, wherein the closed suction catheter assembly comprises: an elongate catheter having a proximal end and a distal end, the catheter being advanceable through the adaptor and an artificial airway; and a cleaning chamber disposed adjacent to the adaptor, the cleaning chamber having a first wiper seal and a valve having an open position and a closed position, the first wiper seal being disposed at the proximal end of the cleaning chamber and the valve being disposed to substantially isolate the distal end of the catheter from the artificial airway when the distal end of the catheter is disposed in the cleaning chamber and the valve is in the closed position. 23.
