Device 14 is coupled to system 12 and adapted to pull on a patient receiver 16 to move a patient 20 received by patient receiver 16 and located on a bed 18 relative to bed 18 to adjust the position of patient 20. Device 14 may be used, for example, to move patient 20 horizontally back toward a head end 22 of bed 18 in the event that patient 20 slides down away from head end 22 due to inclination of head end 22, as shown, for example, in FIGS. 1 and 2.
Patient adjustment device 14 comprises a gripper 24 for gripping receiver 16, a power unit 26, and a tether 28 connecting gripper 24 and power unit 26. Details of a suitable gripper are shown in PCT Application No. PCT/US03/18875 which is incorporated by reference herein. Illustratively, power unit 26 is configured as a winch to wind tether 28 to cause gripper 24 to pull on receiver 16 to move patient 20 relative to bed 18. Power unit 26 is also configured to allow tether 28 to be unwound for extension of gripper 26 to the location of receiver 16. An example of power unit 26 comprises a spool for receiving tether 28 and an electric motor for rotating the spool to wind and/or unwind tether 28. It is within the scope of this disclosure for power unit 26 to be any device which operates to pull on tether 28. User controls (not shown) may be used to control operation of power unit 26.
It is within the scope of this disclosure for patient receiver 16 to be, for example, a bed sheet, a draw sheet, a bed spread, a pad, patient clothing, patient harness, or other grippable material that can be gripped by gripper 24. Illustratively, patient receiver 16 is a sheet located on bed 18. In such a case, device 14 is adapted to pull on the sheet to move patient 20 located on the sheet relative to bed 18 to adjust the position of patient 20.

Tether 28 extends from power unit 26 through an aperture 34 formed in column 36 to gripper 26 for movement through aperture 30 upon winding and unwinding of tether 28. Column 36 may extend all the way between a floor of room 32 and a ceiling of room 32, down from the ceiling without reaching the floor, or up from the floor without reaching the ceiling. Column 36 may be coupled to wall 30 without reaching either the floor or ceiling. In alternative embodiments, column 36 may be spaced from wall 30 of room 32.
Referring to FIGS. 3 and 4, an apparatus 110 comprises an architectural system 112 and patient adjustment device 14 which is coupled to system 112. System 112 comprises a column 136 coupled to wall 30, a bed locator 138 coupled to column 136 and a floor 36 of room 32 for locating bed 18 in room 32 adjacent to column 136, and a tether height adjuster 140. Power unit 26 is positioned in and mounted to bed locator 138. Tether 28 extends upwardly from power unit 26 to height adjuster 140 where it turns to extend generally horizontally in FIG. 4 and at an acute angle in FIG. 3 to gripper 24 through a vertical slot (not shown) formed in column 136.
Height adjuster 140 is configured to adjust the height at which tether 28 exits column 136 through the slot formed therein to thereby accommodate the height of bed 18. To do so, height adjuster 140 is configured for vertical movement relative to column 136 to assume a selected one of a plurality of vertically-spaced positions such as an upper position shown, for example, in FIG. 3 and a lower position, shown, for example, in FIG. 4. The upper position is useful in a variety of situations including the situation shown in FIG. 3 in which head end 22 is inclined. Similarly, the lower position is useful in a variety of situations including the situation shown in FIG. 4 in which head end 22 is lowered and it is desired to transfer patient 20 from a first bed 18a to an adjacent bed 18b. An example of height adjuster 140 comprises a pulley coupled to a pulley mount for mounting the pulley in a selected one of the plurality of vertically-spaced positions. A linear actuator, a motorized jack screw, or any other suitable driver may be used to change the position of pulley. User controls (not shown) may be used to control operation of the driver pulley.

Illustratively, device mount 240 is configured as a telescopic pivot arm assembly comprising proximal and distal portions 242, 244 positioned in telescoping relation to one another. Proximal portion 242 is coupled to an arm mount 246 of headwall 236 for pivotable movement of arm assembly 240 relative to headwall 236 about a horizontal pivot axis 248. Power unit 26 is coupled to distal portion 244 to pivot with arm assembly 240 about axis 248 and to move with distal portion 244 toward and away from proximal portion 242 upon telescoping movement of distal portion 244 relative to proximal portion 242. Tether 28 extends from power unit 26 through an aperture 234 formed in distal portion 244 to gripper 24. Pivotable movement of arm assembly 240 and telescoping movement between portions 242, 244 facilitate adjustment of the height at which tether 28 exits distal portion 244 through aperture 234. Arm assembly 240 thus acts as a tether height adjuster. Such movement of arm assembly 240 further facilitates use of patient adjustment device 14 to move patient 20 toward head end 22, as shown, for example, in FIG. 5, and to move patient 20 from bed 18a to bed 18b, as shown, for example, in FIG. 6. Pivoting movement of arm assembly 240 may pull on tether 28 alone or in combination with operation of power unit 26 and movement of distal portion 244 relative to proximal portion 242.
