This disclosure generally relates to a person support apparatus. More specifically, but not exclusively, the disclosure relates to a co-operative lift system for the person support apparatus.
Generally, a healthcare facility is equipped with a number of person support apparatuses. A lift system may be used to raise a person support apparatus and/or a person, and to move the person support apparatus and/or the person from one position or location to another desired position or location.
This disclosure relates in general to a co-operative lift system for a person support apparatus. The cooperative lift system comprises a master lift, one or more slave lifts, a network channel, and a control panel. The master lift and the slave lift or lifts are operated cooperatively to raise the person support apparatus. A motion of the slave lift or lifts is coordinated with a motion of the master lift. The network channel may be configured to synchronise the motion of the slave lift or lifts with the motion of the master lift. Further, the control panel controls the motion of the master lift.
Fig 1 illustrates an exemplary system comprising a master lift 105, slave lifts 110, straps 115, rollers 120, an overhead rail 125, wheels 130, a person support apparatus 135, tethers 140, a control panel 145, and a network channel 150. The control panel 145 may further comprise an upward button 155, a downward button 160, a rightward button 165, and a leftward button 170.
The master lift 105 may be a motor controlled lift. The master lift 105 may include one or more straps 115 and rollers 120. Strap 115 may be wound over or unwound from roller 120 for a vertically upward and downward motion, respectively, of master lift 105. The roller 120 may be rotated manually, for example by using a hand crank, by a motor (not shown), or similar means known in the art, to wind and unwind strap 115 from roller 120. It is within the scope of the present disclosure for any such motor (not shown) to be hydraulically operated, pneumatically operated, electrically operated, or to be any other appropriate mechanism for rotating roller 120.
Rotating roller 120 causes the winding and unwinding of strap 115 over roller 120, which results in raising and lowering of master lift 105. The master lift 105 is coupled to the overhead rail 125 via the plurality of wheels 130 to permit the translation of master lift 105 along overhead rail 125. It is within the scope of the present disclosure for wheels 130 to be moved along rail 125 manually or to be moved by a motor. Wheels 130 may roll over the overhead rail 125 to achieve the translation motion of the master lift 105.
Master lift 105 may be coupled to the person support apparatus 135 by one or more tethers 140. Tether 140 may be a cord or a rope which may be temporarily coupled to the person support apparatus 135 and may be decoupled at a later stage. Therefore, the master lift 105 is...
