A support structure device is configured to assist a human patient to rise. The support structure includes a tube bent into a shape described by way of a reference frustum such as a four-sided truncated pyramid. Each side of a top rectangular perimeter of the frustum is shorter than a corresponding side of the bottom rectangular perimeter, and each parallel side of a first trapezoidal perimeter of the frustum is shorter than a corresponding parallel side of a second trapezoidal perimeter. The reference frustum has a height between 10 and 18 inches, the top rectangular perimeter has a length between 10 and 16 inches and a width between 6 and 14 inches, and the bottom rectangular perimeter has a length between 12 and 18 inches and a width between 8 and 16 inches.

A system for patient rehabilitation is disclosed. The system includes a first movable frame including an articulating bed, wherein the bed is configured to be selectively articulated to an inclined position, a suspension system, wherein the suspension system is disposed within the articulating bed and is selectively adjustable to accommodate varying patient height, a harness, wherein the harness is selectively engageable with the suspension system, wherein the harness is selectively adjustable to accommodate varying patient sizes, a second movable frame including a walker, wherein the walker includes a pair of legs and a motor, wherein approximation of the two movable frames permits the patient to easily utilize the walker from the bed. A method of using the system for patient rehabilitation is also disclosed.

A stairlift with an elongated rail includes a first side running surface and a second side running surface; and a carriage movable along the rail. The carriage having a first roller including a first roller friction surface which is in frictional engagement with the first side running surface for guiding the first roller; and a second roller including a second roller friction surface which is in frictional engagement with the second side running surface for guiding the second roller; and a first bridge. The first roller being rotatable around a first axis at a first end of the first bridge and the second roller is being rotatable around a second axis at a second end of the first bridge.

A patient support apparatus comprises a base and a support frame. The patient support apparatus also comprises a lift assembly that operates to lift and lower the support frame relative to the base. The lift assembly comprises lift members that extend and collapse to lift and lower the support frame. Guides operate to guide movement of the lift members during operation. In some cases guided bodies coupled to the lift members move passively in the guides. In other embodiments, driven members coupled to the lift members move actively in the guides to cause lifting and lowering of the support frame.

A combination patient-transfer and intraoperative heater device has a top and bottom chamber separated by a barrier. The patient rests on the top chamber, which has a plurality of apertures for discharge of temperature-controlled filtered heated or cooled air at a regulated pressure for patient comfort and mitigation of infection. Heated or cooled filtered air is delivered to the area surrounding the patient, maintaining body temperature during anaesthesia. The bottom chamber has a plurality of apertures. When air pressure is low or off, the bottom chamber is flat and un-inflated. When air pressure is increased, air enters the bottom chamber and the apertures emit air, creating an air cushion facilitating lateral movement of the lifter device. The device performs two functions that now require separate devices and air blowers, it saves space and reduces both costs and complexity in the operating room while mitigating risk of infection.

A system for turning a patient supported on a patient support apparatus includes a U-shaped frame and a rectangular frame pivotably coupled to the U-shaped frame. The rectangular frame includes first and second sheet grippers configured to removeably couple a plurality of sheets to the system and secure the patient between the sheets. The rectangular frame, the sheets, and the patient are configured to rotate at least 180 degrees relative to the U-shaped frame after the U-shaped frame, the rectangular frame, the sheets, and the patient are raised at least a clearance distance above the patient support apparatus.

This invention relates to a linear actuator, comprising an electric motor (10), a worm gear (13, 14), a transmission (15, 16, 19), an outer tube (2) and a spindle (12), said spindle (12) being in connection with the transmission (15, 16, 19), a spindle nut (11) on the spindle (12), a thrust bearing (20) for supporting a shaft end (21) of the spindle (12), wherein the connection between the shaft end of the spindle (12) and the transmission (15, 16, 19) allows a mutual axial movement so that axial forces are only lead through the spindle (12) bypassing the transmission (15, 16, 19) and directly to the thrust bearing (20), wherein a support structure (17, 18, 24, 28) fixedly connects the outer tube (2) and a lower bracket (20, 22), wherein said worm gear (13, 14) drives a shaft (19) included in said transmission (15, 16, 19), which shaft (19) has a driving gear wheel (15) fixedly attached thereto, arranged to transmit torque to a driven gear wheel (16) fixedly attached to the spindle (12), wherein said transmission (15, 16, 19) is arranged to allow axial displacement of the driven gear wheel (16) in relation to the driving gear wheel (15).
