    Abstract: A health bed device for actively supporting neck and shoulder and a method thereof mainly comprises a head air bladder set and a neck and shoulder air bladder set installed in the top surface, near a front end, of a cushion in a mattress. The head air bladder set is not aerated, and the neck and shoulder air bladder set is full of air. Each air bladder of the head air bladder set and the neck and shoulder bladder set is connected to an aerating/deflating device through air tubes. The air tubes are connected to a control device, so the control device derives the aerating/deflating device to aerate or deflate the air bladders of the head air bladder set and the neck and shoulder air bladder set. Each air tube is connected to a pressure sensor. When a pressure sensor detects the pressure of a air bladder increasing suddenly, it can determine that a user changes his/her sleep position from lying on his/her back to lying on his/her side.

  • Publication number: 20110107522
    Abstract: An inflatable bed system (1) includes a primary inflatable section (2) having a centrally located abdomen cavity shaped to allow a user's abdomen to be positioned therein. The system further includes a secondary inflatable section (3), which is independently inflatable and positioned inside the cavity. At least one tertiary inflatable section (15,22) is provided to allow further configuration of the bed. The bed may be inflated by a pump that is operatively connected with a valve which directs the movement of air into each of the inflatable sections under user selection.

  • Patent number: 7921491
    Abstract: A healthy bed for actively supporting a human spine curve mainly comprises a lower base, a plurality of mobilizing devices inside the lower base, a height sensor, a control device, and an inflating device; an upper mattress having an air cushion layer and a plurality of push rods; wherein the control device is used for memorizing the spine curve of a person lying on the upper mattress. When a user lies on the upper mattress, the push rods is are pressed to push the mobilizing devices to move downward, the height sensor detects a moving distance of the mobilizing devices for the control device to determine whether the user is the one whose spine curve is memorized, and if so, then the inflating device is activated to inflate the air cushion layer to let the surface of the upper mattress meet the profile of the spine curve of the user.

  • Patent number: 7913338
    Abstract: A pad (10) of interleaving linear cells (2) has loop straps (1) to hold the central section of the cells (2) linearly in parallel with the cell axis (11), whilst the opposite ends (3) of each cell (2) are secured a pre-determined distance (4) off-set from the cell axis (11). The distance (4) can vary along the length of the pad. By fixing of the ends (3) of the cells (2) at a distance (4) away from the cell axis, each end (3) of the cell (2) is pulled away from the centre axis of the cell, the loop straps (1) and the cell (2) become tensioned, preventing the central cell section from moving or rotating. The resulting cell has been seen to dramatically reduce the movement of a user along the pad with improved user comfort and enhanced pressure relief.

  • Publication number: 20110061169
    Abstract: Disclosed herein is an air mattress including at least two separate zones. A first and second groups of elongate, inflatable cells are disposed alternately within each of the at least two separate zones. An air pump is to supply pressurized air. At least two air distributors are serially connected with the air pump for respectively distributing the pressurized air to the at least two separate zones. Each air distributor is operable to supply the pressurized air to the first and second groups of cells within each of the at least two separate zones. A pressure reducer is serially connected between any adjacent two of the at least two distributors for reducing the pressure of the pressurized air to a downstream one of any adjacent two of the at least two distributors.

  • Patent number: 7886386
    Abstract: Air mattresses primarily intended for hospitals, long-term care facilities and in-home use are described. The mattress includes multiple foam layers and an air sector having multiple resilient foam filled air cylinders. The air cylinders at different locations are filled with foam having different density (firmness); some are filled with multiple layers of foam. Each air cylinder has an air inlet connected to the atmosphere by an inlet valve and an air outlet. The air outlets are either connected to one or more restricted internal check outlet valves in a non-powered air mattress, or connected to a pump via hose connectors in a powered air mattress. The restricted outflow of air from the cylinders in a non-powered air mattress allows the patient to slowly settle into the supportive foam layers for optimal interface pressure distribution. The air cylinders re-inflate when the patient adjusts position or is vacated from the surface.

  • Patent number: 7877829
    Abstract: A system and method for maintaining an air inflation mattress configuration sufficient for patient support and comfort. Infrared illumination levels are measured within individual or groups of inflated mattress chambers. A staggered approach to illumination monitoring of chambers or sections to eliminate crosstalk between the infrared sensors is carried out. Distributed microprocessor controllers established in a network configuration utilizing controller network protocols reduces the wiring and connections necessary for the assembled system. Various mattress cushion construction techniques, such as sewing and or RF welding methods, are used for the creation of individual chambers utilizing specific types of IR translucent, transparent or reflective materials. The construction of the cushions and bladders in the system includes the use of various types of fabrics with low to high air loss qualities as required.
