Abstract

The present disclosure provides a new and innovative method for dynamically managing power and charging rates of multi-pump assemblies. In various embodiments, a computer-implemented method includes monitoring a plurality of pump parameters for a plurality of infusion pumps, assessing a change in the parameter states, establishing charging needs for each infusion pump in the plurality of infusion pumps, and establishing a charging profile for each infusion pump in the plurality of infusion pumps.

Core Innovation

The invention provides an infusion pump system that includes a rack configured to mechanically couple a first infusion pump and a second infusion pump, and a management system communicatively coupled to the pumps via a communication bus. The management system monitors a plurality of pump parameters for the first and second infusion pumps and determines charging needs for each infusion pump using the plurality of pump parameters. Based on the determined charging needs, the management system creates a first charging profile and a different second charging profile for the respective pumps.

Each charging profile specifies times for the pump to enter a charge state and times for the pump to enter a no charge state. The management system transmits at least one command to each infusion pump indicative of the respective charging profile, such that the first infusion pump charges according to the first charging profile and the second infusion pump charges according to the second charging profile. The system can allocate charging activity across pumps, including charging one at a time or charging multiple pumps concurrently.

The invention further includes monitoring and change-based management in which a system receives pluralities of pump parameters at a first time and at a second time, determines a change in the pump parameters, determines new charging needs, creates new first and second charging profiles, and transmits new commands indicative of the respective new charging profiles. Example parameter inputs identified include criticality of a patient’s medication, battery charge state, thermal state, and power supply state, and example monitoring includes measured power and temperature during a charging cycle.

Claims Coverage

The disclosed subject matter includes two independent claims that cover an infusion pump rack system with a management system generating and transmitting per-pump charge/no-charge time profiles, and a computer-implemented method for managing power and charging rates in a multi-pump assembly using monitored pump parameters and change-detection to produce per-pump charging profiles and commands. Across the two independent claims, the main inventive focus is on determining charging needs and generating distinct per-pump charging profiles, including charge state and no charge state times, for multiple pumps, with commands transmitted to each pump indicative of its respective profile.

Per-pump charging profiles with charge-state and no-charge-state times

The management system creates a first charging profile for the first infusion pump and a different second charging profile for the second infusion pump, where the first charging profile specifies times for the first infusion pump to enter a charge state and times for the first infusion pump to enter a no charge state, and where the second charging profile specifies times for the second infusion pump to enter a charge state and times for the second infusion pump to enter a no charge state.

Monitoring plurality of pump parameters to determine charging needs

The management system monitors a plurality of pump parameters for the first and second infusion pumps and determines charging needs for each infusion pump using the plurality of pump parameters.

Transmitting per-pump commands indicative of respective charging profiles

The management system transmits at least one command to each infusion pump that is indicative of the respective charging profile, where the first infusion pump is configured to charge according to the first charging profile and the second infusion pump is configured to charge according to the second charging profile.

Change-based charging needs and updated charging profiles

The method includes monitoring a plurality of pump parameters for the plurality of infusion pumps, determining a change in the pump parameters, determining charging needs for each infusion pump using the plurality of pump parameters and the determined change in the pump parameters, determining a charging profile for each infusion pump, and transmitting a command to each infusion pump indicative of the respective charging profile.

Per-pump charging profiles in multi-pump assembly

The method determines a charging profile for each infusion pump in the plurality of infusion pumps, including a first charging profile specifying times that a first infusion pump is to enter a charge state and times that the first infusion pump is to enter a no charge state, and a second charging profile specifying times that a second infusion pump is to enter a charge state and times that the second infusion pump is to enter a no charge state.

Overall, the claim set centers on computing charging needs from monitored pump parameters, generating distinct per-infusion-pump charging profiles that explicitly include charge-state and no-charge-state times, and transmitting per-pump commands indicative of those respective profiles. The method claim further emphasizes determining charging needs using detected changes in the pump parameters and then updating the charging profiles and transmitted commands accordingly.
