Patent number: 11966397Abstract: A graph database for outbreak tracking and management is disclosed. In an example embodiment, an outbreak management system includes a memory device storing instructions that define a graph database for disease outbreak tracking. The instructions specify for a given host that a host node is created and an episode node is connected to the host node via a ‘case’ link. The episode node is associated with episode parameters that are related to a disease classification of the host. In addition, the instructions specify that an outbreak node is connected to the episode node via a ‘part of’ link to indicate that the host has become part of an outbreak of the disease. The outbreak node is connected to a definition node via a ‘defined as’ link. The definition node specifies disease parameters of the disease that is related to the outbreak node.Type: GrantFiled: November 14, 2022Date of Patent: April 23, 2024Assignees: Baxter International Inc., Baxter Healthcare SAInventors: Paul Randall, Ian Smith, Jonathan Haynes, Sam Wilkinson

Patent number: 11950892Abstract: A handheld device measures all vital signs and some hemodynamic parameters from the human body and transmits measured information wirelessly to a web-based system, where the information can be analyzed by a clinician to help diagnose a patient. The system utilizes our discovery that bio-impedance signals used to determine vital signs and hemodynamic parameters can be measured over a conduction pathway extending from the patient's wrist to a location on their thoracic cavity, e.g. their chest or navel. The device's form factor can include re-usable electrode materials to reduce costs. Measurements made by the handheld device, which use the belly button as a ‘fiducial’ marker, facilitate consistent, daily measurements, thereby reducing positioning errors that reduce accuracy of standard impedance measurements. In this and other ways, the handheld device provides an effective tool for characterizing patients with chronic diseases, such as heart failure, renal disease, and hypertension.Type: GrantFiled: July 28, 2020Date of Patent: April 9, 2024Assignees: BAXTER INTERNATIONAL INC., BAXTER HEALTHCARE SAInventors: Matthew Banet, Marshal Singh Dhillon, Susan Meeks Pede, Lauren Nicole Miller Hayward, Arthur Deptala, Jonas Dean Cochran
