Abstract: A system and method for patient transfer, including patient transfer from a bed to a rollable chair and patient transfer from a wheelchair to a bed. A docking assembly can connect a rollable chair to a bed for transfer. The systems and methods can provide a safe, dignified, and comfortable transfer for patients. A transfer bed, a docking assembly, and a wheelchair can be used together as a system and can reduce the physical and psychological burden of bedridden patients and their caregivers. The transfer bed, docking assembly, and wheelchair can be appropriate for use within a patient's home, nursing home, hospital or any location where a patient is transferred between a bed and a wheelchair. The transfer bed, docking assembly, and wheelchair can be controlled such that a patient is transferred from a bed to a wheelchair or from a wheelchair to a bed.

Abstract: A mattress includes a plurality of air cells. Each cell has a low air permeability envelope and a foam inflation structure that defines one or more voids inside the low air permeability envelope. The foam inflation structures expand when unloaded to cause inflation of the one or more voids. When unloaded, the ratio of the volume of the foam inflation structure to the volume of the one or more voids within the low air permeability envelope is not the same in all the cells.

Abstract: A pneumatic lift including inflatable mattresses stacked one atop another and arranged in air flow communication with one another, but with each being independently deflatable.

Abstract: A mattress has cells with low air permeability envelopes. Check valves permit air flow into cell groups. An inflation structure expands within the cells when not loaded to cause the envelope to fill with air through the check valves. Another mattress has a cell with a primary bladder, a hollow inflation structure in the primary bladder, a secondary bladder in the hollow inflation structure. The inflation structure expands when not under load to cause the primary bladder to fill with air through the check valve. An air cell has a bladder, a check valve permitting air flow to the bladder, and an inflation structure that expands in the bladder when not under load to cause the bladder to fill with air through the check valve. The inflation structure is a cylindrical foam structure with a portion removed along a surface and a D-shaped hollow space within an upper portion thereof.

Abstract: A bolster for resisting rolling of a person off of a mattress, comprising a lateral cushion adapted to be disposed proximate and parallel to an edge of the mattress, and a tensile portion having a means for attachment to said lateral cushion, providing a distributed tensile force to resist a laterally outward displacement of the lateral cushion, the tensile force being transmitted beneath the mattress having a force vector downward and inward. Both the lateral cushion and the mattress may be inflatable, and preferably a pair of lateral cushions, interconnected by a tensile sheet below the mattress, are provided.

Abstract: A transmission for changing rotary motion into angularly reciprocating motion and adapted to be mounted on the output end of a dental power unit of the type having a rotary drive output and used to drive a dental tool. The transmission is comprised of a support member, a driving resinous member supported by the support member for rotary motion, and a driven resinous member supported by the support member for reciprocating angular movement by the support member. The transmission subassembly is formed by the driving resinous member, driven resinous member and support member and adapted to be mounted on the output end of the dental power unit with a rotary drive output mechanically coupled to the driving resinous member. A driving cam surface is disposed on a portion of the driving resinous member. A driven cam surface is disposed on a portion of the driven resinous member.

Abstract: A device for post-operative monitoring by telephone the condition of patients having peripheral arterial occlusive disease. A first embodiment of the device includes an inflatable cuff incorporating a piezo electric film element which generates a signal of varying amplitude. A pressure sensor communicating with the cuff allows transmission of the signal only at a pre-determined cuff pressure. The signal is frequency modulated and transmitted through a modem over the telephone line of the patient to the office of the physician, where it is demodulated to provide a varying direct current for operating a chart recorder. Usage of the device need require only five to ten minutes a day, and the patient can telephone the office of the physician prior to transmission of the signal to identify the patient. In a second embodiment, the piezo electric signal is substituted by a pneumatically generated signal.
