Publication number: 20230298740Abstract: High-accuracy locating systems and methods are used for determining successful caregiver rounding, monitoring whether housekeepers have properly cleaned patient beds, or determining whether patients have ambulated sufficient distances during recovery. Patient beds having at least two locating tags are used for establishing patient care zones around the patient beds. Locating anchors and equipment tags are moved around a patient room to determine optimum locating anchor placement within the patient room based on signal quality values. A locating tag on a patient bed switches roles to operate as a locating anchor in response to the patient bed becoming stationary. A locating tag has a digital compass which is used to determine a field of good ranging relative to a front of a caregiver wearing the locating tag.Type: ApplicationFiled: May 24, 2023Publication date: September 21, 2023Inventors: Timothy J. Receveur, Frederick Collin Davidson, Stephen R. Embree, Britten J. Pipher, Eric D. Agdeppa, Steven D. Baker, Bradley T. Smith, Pamela Wells, Laura A. Hassey, Kiana M. Dezelon, Thomas A.

Patent number: 11559421Abstract: A protective dressing includes an outer dressing and an adhesive layer. The outer dressing includes an opening and a cavity sized to receive a phase-change material (PCM) insert inserted through the opening. The adhesive layer is configured to adhere to a patient's skin surrounding an anatomic site. When adhered to the patient's skin, the PCM insert modifies the patient's skin at the anatomic site. The PCM insert may be removed and replaced with another PCM insert. For example, a warm PCM insert may be replaced with a refrigerated PCM insert.

Publication number: 20090227911Abstract: An active-passive rehabilitation device is disclosed providing natural and relatively unconstrained motion of the treated joint, which promotes drainage and mitigates edema in the extrema. This active-passive rehabilitation device enables the application of adjunctive therapeutic modalities such as cryotherapy units and pneumatic sequential compression devices. Electronic controls allow the active-passive rehabilitation device to be programmed to provide resistive load for Active Range of Motion or Active Resistive Range of Motion (AROM or ARROM) for prescribed therapeutic cycles. Speed, range of motion and therapeutic torque limitations are some of the parameters that may be user controlled and/or programmable. Historical data can be stored in the device and can be downloaded electronically in real-time or at discrete intervals, allowing caretakers to monitor progress and even modify load cycles via electronic communication means.Type: ApplicationFiled: March 2, 2009Publication date: September 10, 2009Inventors: Varad N. Srivastava, James J. Foskett, Michael G. Schneider, John M. Hahn, Greg P. Crowley, Jerome K. Aarestad
