Abstract
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, and a rotational positioning device coupled to the top panel. The internal volume is configured to receive an air flow therein. The rotational positioning device is positioned outside of the internal volume and includes at least one inflatable bladder configured to be inflated from a deflated state to an inflated state. The bladder portion is configured to rotate a patient to a predetermined angle with respect to the top panel in the inflated state.
Claims17
An inflatable transfer mattress, comprising:
- a top panel;
- a bottom panel having a perimeter sealingly coupled to a perimeter of the top panel to define an internal volume therebetween, wherein the internal volume is configured to receive an air flow therein;
- a rotational positioning device coupled to the top panel of the inflatable transfer mattress and positioned outside of the internal volume, wherein the rotational positioning device comprises at least one inflatable bladder configured to be inflated from a deflated state to an inflated state, wherein the at least one inflatable bladder is configured to rotate a patient to a predetermined angle with respect to the top panel in the inflated state;
- and
- a non-woven patient contact layer positioned over the top panel and the rotational positioning device, wherein the non-woven patient contact layer is sealingly coupled to the top panel by a continuous weld formed integrally with a sealing weld formed between the top panel and the bottom panel.
An inflatable transfer mattress, comprising:
- a top panel;
- a bottom panel having a perimeter sealingly coupled to a perimeter of the top panel to define an internal volume therebetween, wherein the internal volume is configured to receive an air flow therein;
- a plurality of stringers positioned within the internal volume, wherein a first edge of each of the plurality of stringers is coupled to the top panel and a second edge of each of the plurality of stringers is coupled to the bottom panel;
- an inflatable bladder coupled to the top panel of the inflatable transfer mattress and positioned outside of the internal volume, wherein the inflatable bladder defines a first bladder portion and a second bladder portion each configured to be independently inflated to define a predetermined angle with respect to the top panel;
- and
- a non-woven patient contact layer positioned over the top panel and the inflatable bladder, wherein the non-woven patient contact layer is sealingly coupled to the top panel by a continuous weld formed integrally with a sealing weld formed between the top panel and the bottom panel.
