Patent number: 9283321Abstract: A system for recording the wasting of fluids includes a waste disposal unit and a sensor system, having a sensor. The sensor can have one or more sensor elements in fluid communication with a fluid as it is wasted from a container into the waste disposal unit. The sensor system is configured to identify one or more drugs within the fluid and record the identity of the one or more drugs in a computer-readable medium electrically coupled to the sensor system.Type: GrantFiled: March 1, 2012Date of Patent: March 15, 2016Assignee: Becton, Dickinson and CompanyInventors: Elizabeth Nelson, Bart D. Peterson, William R. Marshall, Bryan G. Davis

Patent number: 9283323Abstract: The present invention relates to a controller unit and methods for controlling an insulin pump. The controller unit includes a user input that receives a gain factor. The gain factor has been calculated based on historical data in relation to a patient. The controller unit includes a measurement input for receiving data representative of a measured blood glucose level for the patient. Processing logic of the controller unit is configured to apply the measured blood glucose level to a pancreatic beta-cell insulin secretion computational model to predict an insulin output level, apply the gain factor to the predicted insulin output level to determine a patient insulin deficiency level, and calculate a control signal for controlling the insulin output level of the insulin pump based on the patient insulin deficiency level. Methods are provided for optimizing the gain factor based on the historical data in relation to the patient.Type: GrantFiled: August 9, 2012Date of Patent: March 15, 2016Assignee: GENE ONYX LIMITEDInventors: Christofer Toumazou, Pantelis Georgiou, Pau Herrero Vinas, Calvin Sim
