Abstract
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.
Core Innovation
The invention describes a system and computer-implemented method that monitor communications between a server and a plurality of infusion pumps over an infusion pump network. The system identifies performance parameters, including the number of pump messages waiting to be processed, determines weighting factors according to their contributions to network performance, and generates a performance index from normalized parameter values and corresponding weights.
The described system also monitors server and database-server resource measures, displays the performance index and the relative contribution of each performance parameter, and simulates a number of infusion pumps communicating with the server to assess performance under system load and determine an optimal number of pumps or system configuration for a desired load or speed. The supplied content does not include the background section, so the problem being solved is not explicitly described in patent.
Claims Coverage
The two independent claims are claim 1, directed to a system, and claim 11, directed to a computer-implemented method. They cover two corresponding inventive features.
System for generating a weighted performance index
Claim 1 covers a system that monitors pump messages exchanged between a server and a plurality of infusion pumps, identifies performance parameters including messages waiting to be processed, and determines a weighting factor for each parameter according to its contribution to network performance. The system generates a performance index using parameter values divided by corresponding maximum allowed values and multiplied by their weighting factors.
Method for generating a weighted performance index
Claim 11 covers a computer-implemented method that monitors communications between a server and a plurality of infusion pumps, identifies performance parameters including messages waiting to be processed, and determines weighting factors according to the parameters’ contributions to network performance. The method generates a performance index from parameter values divided by corresponding maximum allowed values and multiplied by their weighting factors.
The independent claims cover system and method implementations of monitoring an infusion pump network and generating a weighted performance index from normalized performance parameters.
Stated Advantages
The index supports identification of network bottlenecks by showing parameter contributions to performance.
Device-load simulation allows configurations to be assessed; lower index values indicate better performance.
Documented Applications
Monitoring performance in a network in which a server communicates with a plurality of infusion pumps.
Simulating infusion-pump loads to assess system performance and configurations.
