Patent number: 7007965Abstract: A center-of-gravity tilt-in-space wheelchair includes a base, a seat for supporting an occupant, and tracks supporting the seat for selective seat movement relative to the base. Wheels are adapted to support the base relative to a supporting surface. The tracks serve as rolling or sliding surfaces that allow the seat to rotate with respect to the base. Each track has a constant-radius arc with a focal point that is adapted to be coincident with the center of gravity of the wheelchair occupant. A low-friction supports the base relative to the seat. The low-friction support may include low friction elements that mate with the tracks to support for the tracks. The support can be adjustable to permit the overall tilt angle range of the tracks to be adjusted. The wheelchair seat can be adjusted to maintain the focal point of the constant-radius arc of the tracks coincident with the center of gravity of the wheelchair occupant. The front and rear wheels can be adjusted fore and aft relative to the focal point.Type: GrantFiled: March 31, 2003Date of Patent: March 7, 2006Assignee: Sunrise Medical HHG Inc.Inventors: Todd Bernatsky, Philip Schreiber, Tom Whelan, Wayne Hanson, Steven L.

Publication number: 20050166922Abstract: A method for acclimating a CPAP therapy patient to a prescribed pressure while the patient falls asleep. During an initial startup period, the CPAP apparatus applies a therapeutic IPAP pressure to the patient's airway and a lower initial EPAP pressure to the patient's airway. The EPAP pressure is ramped up to the IPAP pressure over a sufficient time for the patient to fall asleep. In a modified embodiment, both the initial IPAP pressure and the initial EPAP pressure are less than the prescribed therapeutic pressure. The IPAP and EPAP pressures are then independently ramped up to the prescribed therapeutic pressure.Type: ApplicationFiled: January 13, 2005Publication date: August 4, 2005Applicant: Sunrise Medical HHG Inc.Inventor: Michael Knepper

Patent number: 6601271Abstract: A wheel mounting system is comprised of a bearing that is adapted to be positioned between a wheel and the foot tube of a bed. The bearing is comprised of two halve split bearings that are adapted to be fit together to make the complete bearing. The split bearings are adapted to be forced into the wheel and held onto the foot tube by the wheel. A method for mounting a wheel to the foot tube of a bed is comprised of the step of positioning split bearings on the end of a foot tube of the bed with a rib on an interior surface of the split bearings in alignment with an annular groove in the end of the foot tube. The foot tube is then held in a fixture with a backup surface of the fixture abutting the flange of two split bearings.Type: GrantFiled: September 14, 2000Date of Patent: August 5, 2003Assignee: Sunrise Medical HHG Inc.Inventors: Dean R.
