Patent number: 6581225Abstract: The present invention provides an air supply mattress control system for the release of air at a controlled pressure and temperature to a user. A mattress or support member is supplied with pressurized air and has a plurality of force activated nozzle valve assemblies positioned across the upper surface of the mattress. When the upper surface of the valves are forced downward, the valves can release air from a manifold within the mattress. The air can be conditioned and pressurized by a pump and an air conditioning unit. Operation controls can be conveniently positioned adjacent a bed frame for setting the operation conditions of the air mattress.Type: GrantFiled: June 27, 2000Date of Patent: June 24, 2003Inventor: Kazumichi Imai

Patent number: 6546576Abstract: An improved structure of a ventilated mattress with cooling and warming effect is disclosed. The structure comprises a mattress body, a warming/cooling air-delivery controlling box, and a connecting tube. The control box produces warming/cooling air to the mattress body via the connecting tube and the warming/cooling air is released via a plurality of ventilation buttons mounted at the surface of the mattress body. Thereby, the mattress provides the user with a warming/cooling effect.Type: GrantFiled: November 5, 2001Date of Patent: April 15, 2003Inventor: Ku-Shen Lin

Patent number: 6341395Abstract: A ventilating bed cushion includes a frame, a ventilating device, an air supplying device, an upper layer of air-permeable fabric and a lower layer of waterproof fabric. The ventilating device has a polished upper surface and a lower surface. The upper surface is formed with multiple vents. The ventilating device is formed with an inner air guide way for supplying a predetermined amount of air. Therefore, a specific portion of a patient's body lying on the bed cushion can be forcedly ventilated so as to avoid decubitus. In addition, the ventilating bed cushion is widely applicable and can be easily operated. In addition, it has a massaging effect and a low-cost simple structure.Type: GrantFiled: July 25, 2000Date of Patent: January 29, 2002Inventor: Yu-Chao Chao

Patent number: 6171333Abstract: A heating and cooling comforter for heating or cooling a user. The heating and cooling comforter includes an inner bladder comprising a pair of panels coupled together along the outer perimeter of the inner bladder to define an air space therebetween. Each of the panels of the inner bladder has a plurality of spaced apart air apertures therethrough into the air space of the inner bladder. A comforter cover is also included comprising a pair of panels coupled together along the outer perimeter of the comforter cover. The comforter cover has an elongate slit therein between the panels of the comforter cover. The inner bladder is inserted into the comforter cover. A vent cover is included having an arcuate upper wall and an open bottom. An elongate conduit is extended between the from the inner bladder and the vent cover to fluidly connect the air space of the inner bladder to the vent cover.Type: GrantFiled: April 29, 1999Date of Patent: January 9, 2001Inventors: Merle D. Nelson, Linda F. Nelson
