20090216304 | Patient Cooling Enclosure - An apparatus to provide thermal control to a patient comprises a neck member having a surface defining at least one opening, the surface configured to be spaced apart from a neck area of the patient. The neck member includes an air inlet to receive cooled air from an air source. The at least one opening is in fluid communication with the air inlet to direct cooled air from the air source and toward the neck area of the patient to provide the thermal control to the patient. | 08-27-2009 |
20080289107 | Bariatric Bed Apparatus and Methods - A bariatric hospital bed with full feature capability to enhance the care and treatment of bariatric patients. Among the features are fully adjustable and retractable siderails, bed raise-and-lower features, head-up and leg-down features for converting to a seated position, as well as Trendelenburg and reverse-Trendelenburg features. An integral scale assembly and radioluscent capabilities with a built'in X-ray tray are also provided together with redundant, easy-access controls in a pendant as well as in both siderails. An improved footboard is also provided for use as both a foot-rest and a step. | 11-27-2008 |
20080216248 | System and Method for Maintaining Air Inflatable Mattress Configuration - 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. The overall mattress assembly, including the control systems and the methodologies associated with such control systems, provide a unique approach to the maintenance of a consistently comfortable patient support surface. The use of a handheld unit for both programming the system and downloading information about the operation of the system is also anticipated. The specific cushion construction designs associated with the head, body, and foot cushion components of the mattress are tailored to operate specifically with the control capabilities (sensors and air flow regulators) of the invention. | 09-11-2008 |

20080209630 | Patient Repositioning System - A system and method for repositioning a patient. The system comprises a first layer that is liquid impermeable and vapor permeable. The system also comprises a second layer that has a tensile strength that is greater than the first layer. The tensile strength of the second layer is sufficient to allow the system to lift a person being repositioned. The system also comprises a plurality of handles distributed around the sheet. | 09-04-2008 |
20080202527 | PROVIDING AUTOMATED OR MANUAL GUIDANCE ON DYNAMIC PATIENT POSITIONING BASED ON MEASURED VARIABLES FOR VENTILATION CONTROL - Methods and systems that incorporate automated or manual control of ventilation and kinetic rotation therapy are provided. In one exemplary embodiment, an artificial ventilator is used to artificially ventilate one of the patient's lungs, the status of the artificially ventilated lung is determined by measuring one or more ventilation status measures, and one or more of the ventilation status measures is used to provide feedback for controlling the positioning of the patient. In some exemplary embodiments, the feedback is used for automated control of the positioning of the patient, while in other exemplary embodiments, the feedback is used as guidance for manual control of the positioning of the patient. | 08-28-2008 |
20080201843 | Patient Repositioning and Limb Management System - A system for repositioning a patient. The system may be coupled to a structural support system or framework that extends above a bed. The system may be translated transversely and longitudinally and placed in one of multiple locations above the bed. | 08-28-2008 |
