Publication number: 20140222450Abstract: Via communications with an association management resource, an operator of a respective fluid delivery system can associate a medical device (fluid pump) with a particular entity such as a patient, location, one or more other medical devices, the caregiver, etc. Thereafter, the operator of the fluid delivery system is able to better manage use of the fluid delivery system based on relevant medical information, which is accessible as a result of creating the association. For example, the association management resource gathers and stores information associated with the entity prior to the operator providing the input associating the fluid delivery system with the entity. After the operator of the fluid delivery system creates the association, the medical information associated with the entity is immediately available to the fluid delivery system and/or corresponding operator of the fluid delivery system.Type: ApplicationFiled: February 4, 2014Publication date: August 7, 2014Inventors: George W. Gray, William C. McQuaid, Jesse E. Ambrosina

Publication number: 20100121873Abstract: The present application relates to improving healthcare practices in clinical facilities. In a facility that utilizes electronic patient charts (16), a correlation processor (24) discovers correlations between events as defined by a user of the system. The user first selects an anchor event. Then the user selects a related event. Both the anchor events and the related events can be run through appropriate filters to eliminate unwanted results. The user then defines a relationship between the anchor event and the related event. The correlation processor (24) then searches through the patient charts (16) for the correlation as defined by the user. Results are displayed for the user in a format designated by the user.Type: ApplicationFiled: March 26, 2008Publication date: May 13, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: George W.
