Devices, systems and methods for quantifying bolus doses according to user parameters

摘要

A fluid delivery system (1000) for administering a bolus dose of therapeutic fluid in a user's body, the system comprising: a pump (1005) for administering therapeutic fluid in the body; and at least one processor (10) that includes instructions operating on it, the processor (10) being configured to: receive a current blood glucose level (CBG) from the user; receive a trend of the user's BG, which includes a direction and / or rate of change of the user's blood glucose level (BG); receive one or more first additional parameters related to the user; receive one or more second additional parameters related to the user, one or more second additional parameters that are selected from a group consisting of level of physical activity, level of emotional stress, level and / or tendency of blood ketones, pH level blood and / or tendency, presence of a disease and / or menstruation and body temperature; and determine a bolus dose based on the CBG, the tendency of BG, one or more additional first parameters related to the user and one or more second additional parameters, so that administering the bolus dose to the user compensates for a change in a level BG of the user in which the processor (10) includes instructions configured to: determine an initial bolus dose based on the one or more additional parameters related to the user and the CBG; and determine the bolus dose based on the initial bolus dose multiplied by one or more multiplier values or an average of a plurality of multiplier values, the or each multiplier value represents a magnitude of a particular user parameter on a relative scale, the one or more multiplier values including at least one of: a multiplier value that correlates with the BG trend; and a multiplier value correlated with at least one of the one or more second parameters.
