A convertible wheeled chair is easily changed by an attendant into a gurney of the same height as a patient bed. During the process of transferring a patient from an upright position to a reclining position, convertible wheeled chair shifts the center of gravity of the patient rearwardly, and therefore does not give the patient a sensation of sliding from the chair.

The present invention relates to a vibratory patient support system for providing therapeutic vibrational action or forces to a patient suffering from a respiratory ailment. The vibratory patient support system includes a rigid support frame such as a bed frame, a plurality of inflatable sacs supported upon the support frame with each sac having an upper surface so that the plurality of sacs forms a patient support surface. The inflatable sacs are pressurized and maintained at a predetermined pressure. This predetermined pressure may be a patient height and weight specific pressure profile. A vibrating component is provided separate from the apparatus for pressurizing and maintaining the air sacs at the predetermined pressure. The vibrating component vibrates at least a portion of the patient support surface at a predetermined frequency. In this manner, the plurality of air sacs are maintained at their predetermined pressure and the portion of the patient support surface is simultaneously vibrated at the predetermined frequency. The vibrating means are further variably controllable so that an operator can vary the frequency, magnitude or amplitude, and duration of the vibrating therapy. The vibratory patient support system may include a specialty low air loss bed configuration including vibrating means for vibrating a portion of the patient support surface of the low air loss sacs at the predetermined frequency.

A surface pad apparatus for a surgical table includes a body pad section positioned to lie beneath the torso of the patient and including a pad core and a cover defining an interior region configured to receive the pad core. The pad core includes a thermal pad having a casing defining a channel configured to receive a thermoregulation fluid. The apparatus also includes a leg pad section longitudinally spaced apart from the body pad section and positioned to lie beneath the lower legs and feet of the patient. The leg pad section is coupled to the body pad section and includes a pad core and a cover defining an interior region configured to receive the pad core. The pad core includes a thermal pad having a casing defining a channel configured to receive the thermoregulation fluid. The channel of the thermal pad of the leg pad section is in fluid communication with the channel of the thermal pad of the body pad section so that thermoregulation fluid can pass therebetween.

A surface pad system for a surgical table includes a cover having an upwardly-facing patient-support surface defining an interior region of the surface pad system, and a vacuum bead bag received in the interior region. The vacuum bead bag includes a flexible cover defining an interior region containing compressible beads including a lower layer of compressible beads and an upper layer of compressible bead separated from the lower layer of compressible beads by a membrane made from a flexible material. The system also includes a bladder received in the interior region of the cover and positioned to lie beneath the vacuum bead bag. The bladder defines an interior region and is inflatable when pressurized fluid is received in the interior region of the bladder so that the vacuum bead bag conformingly engages the patient on the patient-support surface when the bladder is inflated.

A proportional flow control valve is provided for use with low air loss patient support systems. The valve includes a valve housing having an inlet and an outlet defined therein with a valve passage defined through the housing between the inlet and outlet. A chamber is defined in the housing, the chamber further including a nipple cavity defined in the bottom thereof and a cam stop extending from the bottom into the chamber. A valve spool is rotatably disposed within the chamber. The valve spool includes an alignment nipple fitting into the nipple cavity and a cam defined on the bottom thereof through a predetermined rotational arc. The cam and cam stop cooperate to limit the rotational arc of the valve spool within the chamber. A proportional flow control groove is defined in the valve spool. The flow control groove establishes linear air flow through the valve depending on the angular displacement of the spool within the chamber. A motor is provided mounted to the housing to rotate the valve spool within the chamber and, preferably, a torque limiting clutch is disposed between the motor and valve spool. The valve spool further includes a friction reducing substance coated thereon or impregnated therein, such as teflon or the like, to reduce binding of the valve spool within the chamber.
