  • Patent number: 7418751
    Abstract: An apparatus adjusts the pressures of a therapeutic mattress surface in accordance with the angular position of that surface. The apparatus comprises an angular position sensor and a rotation sensor which are housed together in an enclosure having a top surface in the form of a circular plate. The circular plate mounts either on the surface of the mattress or on the bottom of a bed frame supporting the mattress. The angular position and rotation sensors measure the horizontal plane referenced perpendicular to the direction of the force of gravity. The apparatus further comprises a controller blower valve assembly which processes data received from the angular position and rotation sensors to maintain, increase, or decrease the pressures within the mattress.

  • Patent number: 7167103
    Abstract: A transit center apparatus is provided having one or more modules attachable to a transit stop pole to provide one or more of the following conveniences to a transit stop patron: information in an optionally illuminated modular display apparatus, overhead illumination, video camera surveillance, and wireless communication. These conveniences are preferably provided through an overhead assembly and a rugged information display case. The overhead assembly houses one or more of the group consisting of solar cells, a rechargeable battery pack, overhead lights, a cell phone antenna, camera, and related circuitry. The information display case provides backlighting and houses a switch assembly. The display case is preferably constructed from extruded, interlocking aluminum frame members and is easily installable on existing support poles.

  • Patent number: 6904631
    Abstract: A bariatric treatment system providing a comprehensive array of therapeutic services for the morbidly obese patient is disclosed. The treatment system generally comprises a stable bed frame upon which is mounted a low air loss therapeutic mattress system. Integrated hardware and software controls provide such therapies as pulsation, percussion, rotation, cardiac chair and Trendelenburg. Means are disclosed whereby the bariatric patient may safely and comfortably enter and exit the bed with relative ease. The bed is adaptable for transport within a hospital, including such features as a TRANSPORT MODE wherein the bed's lateral axis is minimized and battery backup to maintain necessary therapies during patient transport. A plurality of control means are disclosed for simplification of caregiver workload and ease of patient utilization.

  • Patent number: 6728983
    Abstract: A direct data and power interface is provided to the patient support platform of a therapeutic bed that allows for a complete rotation of the patient support platform in either direction. To ensure that the data and power interface is not articulated beyond its physical limit as a result of manually rotating the bed in the emergency backup mode, a mechanical stop is provided to limit rotation of the patient support platform to about 730 degrees. Sensors are provided to detect activation of the mechanical stop.

  • Patent number: 6671905
    Abstract: A prone positioning therapeutic bed comprises a base frame, a patient support platform rotatably mounted on the base frame for rotational movement about a longitudinal rotational axis, a drive system for rotating the patient support platform on the base frame, and an upright end ring at the head of the bed with a central opening for routing patient care lines and a removable upper section for improved access to a patient's head. The patient support platform preferably has pivotally mounted side rails that fold underneath the patient support platform and straps with strap connectors that indicate whether the straps are sufficiently tensioned. A direct, wired electrical connection between the patient support platform and the base frame allows full rotation of the patient support platform in either direction. A manually operable lever disengages the patient support platform from the drive system to allow manual rotation of the patient support platform.

  • Patent number: 6566833
    Abstract: A prone positioning therapeutic bed comprises a base frame and a patient support platform rotatably mounted on the base frame for rotational movement about a longitudinal rotational axis and a drive system for rotating the patient support platform on the base frame. A special head restraint apparatus maintains proper patient alignment during rotation. A weight monitoring system monitors a patient's weight over time. A touch screen user interface provides programmable therapy settings and displays statistics about past treatment. Circuitry is provided to minimize the risk that the failure of any single device or software program could endanger a patient. A “CPR” button is provided to arrest any program of therapy and return the patient support platform to a supine position.
