摘要:
A bed comprises an inflatable mattress supported on a platform of articulable links by a support system mounted on a weigh frame. The weigh frame is supported on a base frame supported relative to a floor. A pneumatic system includes a platform-mounted blower directing air through passageways in the articulable links. An exhaust passageway parallels the pressure passageway for exhausting opposite the blower. Air flow into and out of air cells in the mattress are controlled by valves coupling the pressurized air chamber and exhaust chamber to cell ports. A connector assembly is used to couple the cells to the platform, to adjacent cells, and to tubes connected to other cells. An alternative pneumatic system includes fans distributed on the platform in association with sets of mattress cells. A footboard assembly is formed as two gates that swing out from the foot of the bed. Each gate has a storable tray that is positionable on either side of the gate. A headboard has a removable central panel for providing emergency patient access. Additionally, each corner of the headboard has a telescoping equipment support post positionable at a variety of heights and having equipment supports that automatically drop into place upon removal from storage in the headboard. A three-point weight sensing system tracks patient weight and generates pre-exit and exit alarms based on sensed movement of the patient on the mattress. A portable control unit wraps around a guard rail to provide both patient and nurse controls, and uses a unitary membrane to cover exposed faces of the controls and resiliently wrap around the guard rail. Selectively engagable guide or fifth wheels are mounted to the base frame to provide direction stability during bed movement. The platform is articulable to allow a patient to enter or exit the bed in a standing position. An adjustable stand up board is selectively positionable at the foot of the bed to take the patient's weight during this process. A vertically telescoping guard rail elevation system provides energy storage to resist lowering and assist raising the guard rail. A brace is provided for seating the platform on the weigh frame when the bed is in a low position and to assist in movement of the bed longitudinally when in the low position. An expanding joint between panels allows the panels to separate with increasing angle between the panels. A hydraulic valve produces linear changes in fluid flow with linear changes in a valve plunger.

摘要:
A bed configured to support a patient having a weight comprises a frame, a patient support, and a plurality of sensors coupled between the frame and the patient support. Each of the plurality of sensors is configured to generate an analog signal in response to a portion of the weight of the patient on the patient support. The bed also comprises a circuit coupled to the plurality of sensors to receive the analog signals therefrom. The circuit includes a plurality of analog-to-digital converters, each analog-to-digital converter being coupled to one of the sensors to generate a separate digital signal for each of the plurality of sensors, and a processor coupled to the plurality of analog-to-digital converters to determine the weight of the patient on the patient support.

A bed comprises an inflatable mattress supported on a platform of articulable links by a support system mounted on a base frame. A connector assembly is used to couple the cells to the platform, to adjacent cells, and to tubes connected to other cells. The mattress includes lateral cushions or cells that have a general triangular shape with larger upper cells forming a patient support surface and smaller base cells laterally supporting the upper cells. The upper cells may be elevated at the ends to form a broad U or V shape. Alternative embodiments include shorter base and upper cells with a box-shaped restraining cell on each end that extends above the upper cells. Modified upper cells have end pouches that store separate restraint cells when deflated, and provide inflation pressure when removed by a fixed connecting tube. The restraint cells are positionable along the host upper cell and anchor to catches mounted on the adjacent base cells.

A sensor array pad for sensing the pressure distribution under a saddle on the back of a horse includes a membrane made of first and second, identical substantially non-stretchable, flexible membrane portions. The membrane portions have adjacent facing edges that are joined at two spaced-apart tabs. A plurality of sensors are distributed substantially uniformly on the membrane, with each sensor occupying a predetermined surface area. Conductors are mounted on the membrane to extend between the sensors and a position along the perimeter of the associated membrane portion to provide for external connection with monitoring equipment. The membrane portions further each have a pair of slits extending from a mid-region spaced from the respective facing edge outwardly in diverging directions along lines passing outside the predetermined areas of the membrane occupied by the sensors. The slits define an upper section extending generally along the spine of a horse and a side section extending down the side of the horse away from the spine. When placed on the back of a horse with the facing edges extending along the spine, the membrane generally conforms to the back of the horse with the upper and side sections separating by spreading of the slits. The membrane may also be stretchable between the individual sensors. Pressures sensed by the sensors are input to a computer which generates a display of the pressure distribution.
摘要:
This invention is a simple device and method of measurement that employs a mechanical device having articulated transverse linkages comprising a parallelogram assembly having the first arm as one link, an opposing link, and further comprising a hub member, with transverse opposing wings each of the wings being pivotingly joined to the hub member for defining shape and indicia to determine a series of angles, and thereby be able to describe angles and arcs in order to determine the convex and concave portions of polyform shapes—in this preferred embodiment relating to animal backs and their corresponding saddles. A method and formula to adjust the shape of such a device to compensate for the weight of the rider relative to the weight of the animal as well as additional factors is also provided by this process. Additional calibration can also be refined by employing interface pressure measurement.
