1. A patient support apparatus comprising:
- a base,a tub supported by the base and having a pair of side outer walls, a pair of end outer walls extending between the side outer walls, a bulkhead wall positioned to lie between the end outer walls and extending between the side outer walls so that a first compartment is defined between the bulkhead wall and one of the end outer walls and so that a second compartment is defined between the bulkhead wall and the other of the end outer walls, and a set of inner walls arranged to define a mattress well, the inner walls being positioned to lie in the first compartment, the inner walls being spaced apart from the bulkhead wall and the pair of side outer walls so that an air delivery channel is defined therebetween, the bulkhead wall being formed to include an opening in fluid communication with the first and second compartments,a mattress supported in the mattress well and having a patient-support surface,a deck coupled to the tub and configured to cover at least a portion of the first and second compartments, the deck being formed to include at least one air vent in fluid communication with the air delivery channel, anda fan positioned to lie in the second compartment, the fan being operable to move air from the second compartment, through the opening formed in the bulkhead wall, into the air delivery channel, and through the at least one air vent so that an air curtain is generated adjacent to the mattress.

Abstract
A patient support and environmental control apparatus comprises a frame and an upwardly-facing patient-support surface carried by the frame. An air curtain generator is mounted to the frame. The air curtain generator provides first and second curtains of air. The patient-support surface has a perimeter and the first and second curtains of air originate adjacent to the perimeter and converge at a point positioned to lie above the patient-support surface. The first and second curtains of air cooperate with the patient-support surface to define a patient space.

16. A patient support apparatus comprising:
-
a base, a tub supported by the base and formed to include a first compartment and a second compartment separated from the first compartment by a bulkhead wall, the tub being formed to include a mattress well positioned to lie in the first compartment, the tub being formed to include an air delivery channel extending around at least a portion of the mattress well, a divider supported in the second compartment and arranged to subdivide the second compartment into a first space above the divider and a second space below the divider, the divider being formed to include a divider opening so that the first space is in fluid communication with the second space, the bulkhead wall being formed to include an opening in fluid communication with the air delivery channel and with the second space, a mattress supported in the mattress well and having a patient-support surface, a deck coupled to the tub and configured to cover at least a portion of the first and second compartments, the deck being formed to include at least one air vent in fluid communication with the air delivery channel, and a fan positioned to lie in the second space, the fan being operable to move air from the first space, through the divider opening into the second space, through the opening formed in the bulkhead wall, into the air delivery channel, and through the at least one air vent so that an air curtain is generated adjacent to the mattress. - View Dependent Claims (17, 18, 19, 20)

21. A tub for use with a patient-support apparatus, the tub comprising:
-
a set of outer walls including a pair of side outer walls and a pair of end outer walls extending between the side outer walls, a bulkhead wall positioned to lie between the end outer walls and extending between the side outer walls so that a first compartment is defined between the bulkhead wall and one of the end outer walls and so that a second compartment is defined between the bulkhead wall and the other of the end outer walls, the bulkhead wall being formed to include an opening so that the first compartment is in fluid communication with the second compartment, and a set of inner walls arranged to define a mattress well, the inner walls being positioned to lie in the first compartment, the inner walls being spaced apart from the bulkhead wall and the pair of side outer walls so that an air delivery channel is defined therebetween.
