1. An endoscope sheath comprising: a sheath tube extending along a longitudinal axis between a proximal end and a distal end, the sheath tube defining a passageway that is configured to receive a tubular portion of an endoscope;a hub connected to the proximal end of the sheath tube; anda hub adapter engaging the hub and configured to engage the endoscope, the hub adapter having only a single port, the single port is in communication with both an irrigation source and a suction source, the single port is adapted to provide irrigation fluid from the irrigation source and suction from the suction source to the same passageway that is configured to receive the tubular portion of the endoscope;wherein the hub is separable from the hub adapter so that the hub and the sheath tube are separable from the hub adapter and the endoscope,wherein the sheath tube is rotatable about the longitudinal axis without rotation of the hub adapter, andwherein the sheath tube is restricted from moving axially along the longitudinal axis relative to the hub adapter;wherein one of the hub adapter and the hub includes a flange and the other of the hub adapter and the hub includes a channel;wherein the flange rotationally engages the channel so that the sheath tube is rotatable about the longitudinal axis;wherein after the flange engages the channel, a proximal side and a distal side of the flange is constrained within the channel so that the sheath tube is restricted from moving axially along the longitudinal axis;wherein the flange includes a plurality of radial projections and the channel includes a plurality of mating radial notches, and after the radial projection are received into the radial notches the flange is rotatable within the channel; andwherein after the flange is engaged in the channel, aligning the radial projections with the mating radial notches enables the sheath tube and the hub to be separable from the hub adapter and the endoscope. 2. The endoscope sheath of claim 1, wherein the hub adapter includes an arm configured to engage a light post extending from the endoscope so that the hub adapter is restricted, from rotating when the sheath tube rotates about the longitudinal axis. 3. The endoscope sheath of claim 2, wherein the distal end of the sheath tube includes an angled tip and the sheath tube is rotatable about the longitudinal axis so that the angled tip can be repositioned relative to a distal end of the endoscope without rotation of the endoscope or the hub adapter. 4. The endoscope sheath of claim 3, wherein the channel includes a second series of radial projections cooperating with the radial projections of the flange to retain the flange within the channel and to restrict the sheath tube from moving axially along the longitudinal axis relative to the hub adapter. 5. The endoscope sheath of claim 2, wherein the arm includes a yoke configured to engage the light post so that the hub adapter is prevented from rotating about the longitudinal axis. 6. The endoscope sheath of claim 1, wherein the sheath tube comprises only a single lumen extending between the proximal end of the sheath tube and the distal end of the sheath tube, the single lumen defining the passageway. 7. The endoscope sheath of claim 1, wherein a cross section of the sheath tube is generally the same size as a cross section of the tubular portion of the endoscope, and wherein the cross-section of the sheath tube remains generally constant between the proximal end of the sheath tube and the distal end of the sheath tube. 8. A cleaning system comprising: A. an endoscope sheath comprising: a sheath tube extending along a longitudinal axis between a proximal end and a distal end, the sheath tube having only a single lumen extending between the proximal end and the distal end, the single lumen defining a passageway that is configured to receive a tubular portion of an endoscope;a hub connected to the proximal end of the sheath tube; anda hub adapter engaging the hub and configured to engage the endoscope, the hub adapter comprises only a single port,wherein the hub is separable from the hub adapter so that the hub and the sheath tube can be separated from the hub adapter and the endoscope;wherein the hub and the sheath tube can rotate about the longitudinal axis without rotation of the hub adapter and the endoscope,wherein the hub adapter includes a flange and the hub includes a channel,wherein the flange rotationally engages the channel so that the sheath tube is rotatable about the longitudinal axis, andwherein after the flange engages the channel, a proximal side and a distal side of the flange is constrained within the channel so that the sheath tube is restricted from moving axially along the longitudinal axis;wherein the flange includes a first series of radial projections and the channel includes a series of mating radial notches,wherein after the first series of radial projections are aligned with and then received into the series of mating radial notches the flange is rotatable within the channel;wherein after the hub adapter and the hub are engaged, aligning the first series of radial projections with the series of mating radial notches enables the sheath tube and the hub to separate from the hub adapter and the endoscope;wherein a cross section of the sheath tube is generally the same size as a cross section of the tubular portion of the endoscope;B. a source of irrigation fluid; andC. a source of suction;wherein the source of the irrigation fluid and the source of the suction are both in fluid communication with the single port located on the hub adapter, andwherein the single port is adapted to provide the irrigation fluid or the suction to the same passageway that is configured to receive the tubular portion of the endoscope. 9. The cleaning system of claim 8, wherein the system comprises: an irrigation line in communication with the source of irrigation fluid;a suction line in communication with the source of the suction;a common fitting in communication with both the irrigation line and the suction line; anda common line in communication with the single port on the hub adapter;wherein the irrigation fluid or the suction is supplied to the passageway via the common line, the common fitting, and the single port. 10. The cleaning system of claim 9, wherein the system comprises a valve, the valve is located between the source of the suction and the common fitting so that either the irrigation fluid is supplied to the passageway or the suction is supplied to the passageway.
