Patent number: 11501877Abstract: A distributed network system and method includes a processing unit configured to manage safety data for a plurality of medical devices, a database software component in communication with the processing unit, and a monitoring software component in communication with the processing unit. The monitoring software component is configured to monitor a number of messages between a number of medical devices and the processing unit, to process performance parameters to generate an overall performance index, and to generate an output that is viewable by a user. The output includes relative contributions of each of the performance parameters to the overall performance index, where the overall performance index is generated using a weighting factor associated with each of the performance parameters. The performance parameters include the number of messages waiting to be processed, which has the largest weighting factor, and a disk queue length, which has the smallest weighting factor.Type: GrantFiled: April 16, 2019Date of Patent: November 15, 2022Assignee: ICU Medical, Inc.Inventors: Christopher Egan Kohlbrecher, Jonathan Leigh Walton, Daniel Chien-Yu Hsu, Michael Paul Myers

Patent number: 11376361Abstract: A system and method for monitoring and delivering medication to a patient includes a controller that has a control algorithm and a closed loop control that monitors the control algorithm. A sensor is in communication with the controller and monitors a medical condition. A rule base application in the controller receives data from the sensor and the closed loop control and compares the data to predetermined medical information to determine the risk of automation of therapy to the patient. The controller then provides a predetermined risk threshold where below the predetermined risk threshold automated closed loop medication therapy is provided. If the predetermined risk threshold is met or exceeded, automated therapy adjustments may not occur and user/clinician intervention is requested.Type: GrantFiled: June 21, 2018Date of Patent: July 5, 2022Assignee: ICU Medical, Inc.Inventors: Timothy L.
