Abstract: A support frame is positioned over a hospital bed to assist in lifting and turning a patient on a sheet. In addition to the lifting mechanism, the frame has a carriage mechanism which can carry a lifted patient beyond the side or the end of the bed. The patient can also be lifted from the bed, the frame narrowed, and the patient transported to other locations in the hospital and then back to the bed without any severe physical handling. A bath water and waste water cart is used to bath a patient and to catch waste water. A drain pan is placed under the patient to catch bath water and return the water to a drain water tank on the cart.

Abstract: A self-cleaning air filter includes a tubular housing and an annular filter cartridge removably and rotatably supported in the tubular housing. A removable cover at one end of the housing provides access to the housing for insertion and removal of the filter cartridge. A first rotary support for one end of the filter cartridge is mounted on the removable cover and includes a short shaft supported by the cover and a hub assembly rotatably mounted on the short shaft. The hub assembly is releasably secured to one end of the filter cartridge. A pair of successively smaller diameter tubular extensions are provided at the other end of the housing through which clean air passes outwardly from the filter. A second rotary support for the filter cartridge includes a turntable mounted inside of the housing by a tubular neck which is journaled inside of the first tubular extension. The turntable has a peripheral flange which snugly engages the other end of the filter cartridge with a friciton fit.
