A smart sling device includes a body; a support rod installed at the body; and a sling member installed at the support rod and inserted under a patient to support the patient therebelow, and the sling member includes an expanding unit having an accommodation space for accommodating air therein, the expanding unit expanding due to a pneumatic pressure generated by the accommodated air to support the patient therebelow; and an expansion limiting unit installed at the expanding unit to limit expansion of the expanding unit in one direction.

An inflatable transfer mattress includes a top panel, a bottom panel having a perimeter sealingly coupled to a perimeter of the top panel to define an internal volume therebetween, a first wedge pocket coupled to an outer surface of the top panel, and a first inflatable wedge. The internal volume is configured to receive an air flow therein. The first inflatable wedge is sized and configured to be inserted into the first wedge pocket and is configured to be transitioned from a deflated state to an inflated state. The first inflatable wedge is configured to rotate a patient to a predetermined angle with respect to the top panel in the inflated state.

A method for hip distraction includes positioning a patient on a slide-resisting pad placed on a surgical table; tilting the surgical table so that the patient is in a first degree of inclination; applying a distraction force to a leg of the patient while the patient is in the first degree of inclination so that a hip joint of the patient is distracted, wherein the distraction force is opposed by a combination of a slide-resisting friction force provided by the slide-resisting pad and a gravitational force attributable to the first degree of inclination; reducing the tilt of the surgical table in accordance with a reduction of the distraction force over time so that the patient is in a second degree of inclination; and performing at least a portion of a surgical procedure on the distracted hip joint while the patient is in the second degree of inclination.

An air supply supplies air to multiple different inflatable devices. The air supply includes an air compressing device, and at least two pressure valves. The air supply operates to introduce air from the first pressure valve to a first inflatable device at a first pressure that is within a first air pressure range. The air supply also operates to introduce air, on demand, from the second pressure valve to a second inflatable device at a second pressure within a second air pressure range while continuing to supply air to the first inflatable device at a pressure within the first air pressure range. The second pressure and/or the second pressure range is different from the first pressure and/or the first pressure range.

A system includes an inflatable device having a top sheet of material and a bottom sheet of material, wherein the top sheet of material is connected to the bottom sheet of material thereby defining a cavity therebetween to be inflated. The device further includes a plurality of passages in the bottom sheet extending from the cavity to an exterior of the device, wherein the passages are configured to permit air to pass from the cavity to the exterior of the device. The inflatable device further includes a plurality of inflation-limiting members connecting the top sheet to the bottom sheet, and an input configured for receiving air to inflate the device. The system further includes an absorbent body pad configured to be positioned between the top sheet of material and a patient positioned on the inflatable device.

A transfer mattress includes a top panel, a bottom panel, an outer stringer and an inner stringer. The top panel has a perimeter including a proximal edge and a distal edge, wherein a central longitudinal axis extends from the proximal edge to the distal edge. The bottom panel has a plurality of perforations and a perimeter including a proximal edge and a distal edge coupled to the perimeter of the top panel. The outer stringer and inner stringer each have a superior edge coupled to the top panel and an inferior edge coupled to the bottom panel and a longitudinal portion that is substantially parallel to the central longitudinal axis. The inner stringer is positioned between the central longitudinal axis and the outer stringer.

A transfer mattress includes a top panel and a bottom panel. The bottom panel is engaged with the top panel to form an internal chamber. The bottom panel includes an air permeable portion and an air impermeable portion, wherein the air permeable portion is constructed from an air permeable woven material. The permeable portion and the impermeable portion are configured such that air is able to escape from the internal chamber through the permeable portion and air is not able to escape from the internal chamber through the impermeable portion.

A mattress includes a pair of first panels connected to each other and defining a first air pocket therebetween; and a pair of second panels connected to each other and defining a second air pocket therebetween. The pair of first panels and the pair of second panels are operatively connected to each other defining a space between the pair of first panels and the pair of second panels. The pair of first panels and the second pair of panels each have collapsible pleats to control a volume of the space.

A trolley system configured to transport a patient within an MRI environment includes a patient support portion, a base portion configured for movement relative to a floor, a lift coupled to the patient support portion and the base portion, an electric motor coupled to the lift, and an electric blower coupled to the patient transfer device. The lift is configured to change the elevation of the patient support portion relative to the base portion. The motor is mounted such that the elevation of the motor is fixed relative to base portion. The trolley system is positionable adjacent an MRI apparatus within the MRI environment and the magnetic field of the MRI does not interfere with the operation of the motor or blower. The trolley system may further include a patient transfer device having an air bearing. The blower is configured to deliver air to the air bearing.
