Infusion Pump Alert Threshold Adjustment for Fluid Limit Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid delivery systems face inefficiencies due to frequent overriding or reprogramming of fluid delivery limits by operators who may not fully understand the appropriate limits, leading to excessive alerts and reduced efficiency in fluid administration.
Innovation Solution
A system that collects and analyzes infusion pump data to identify excessive alerts, allowing for automated adjustment of fluid delivery limits based on alert thresholds and user input, reducing the need for manual analysis and improving compliance with predefined limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluid delivery limits are set with hard upper limits to prevent errors, then patient safety is improved, but operator flexibility and ease of operation deteriorate
Solution Approach 1:
The system dynamically adjusts alert thresholds based on fluid type and clinical context rather than using fixed hard limits. The processing circuit receives programming parameters, identifies the fluid type, and selectively applies soft or hard limits based on pre-configured settings for each fluid, allowing the system to adapt between safety and flexibility depending on the specific clinical scenario.
Solution Approach 2:
The system changes the parameter of alert threshold strictness based on fluid type identification. Different fluids have different configured limit types (soft or hard) stored in memory, and the processing circuit selectively applies appropriate limit types by comparing the programmed rate against the configured limits for the specific fluid being administered.
2Ease of operation
If soft upper limits with alerts are used to allow operator discretion, then operator flexibility is improved, but excessive alerts and reduced productivity occur
Solution Approach 1:
The system applies different alert threshold qualities locally based on fluid type. Each fluid in the library can be configured with specific soft or hard limits for different parameters (rate, concentration, etc.), allowing the system to be restrictive where needed and flexible where appropriate for each specific fluid rather than applying uniform limits across all fluids.
Solution Approach 2:
The system automatically identifies the fluid type from the programming parameters and selectively applies the appropriate pre-configured limits without requiring operator intervention to determine which limit type to use. The processing circuit autonomously determines whether to apply soft or hard limits based on the fluid identification and pre-stored configurations.
3Reliability
If fluid library limits are programmed by administrators, then system reliability is improved, but device complexity and difficulty of maintenance increase
Solution Approach 1:
The processing circuit performs multiple functions: it identifies fluid type from programming parameters, retrieves the appropriate pre-configured limits from memory, compares the programmed rate against those limits, and determines whether to generate an alert or allow delivery. This multi-functional approach consolidates what would otherwise require separate systems into a single integrated circuit.
Solution Approach 2:
The pre-configured fluid library acts as an intermediary between administrative policy and real-time pump operation. Administrators configure limits once in the library, and the processing circuit automatically applies these pre-established rules during fluid delivery, mediating between the need for administrative control and operational simplicity.

AI summary
A fluid delivery system displays, on a display screen, fluid identifiers including a first fluid identifier indicating a first fluid and a second fluid identifier specifying a second fluid. The fluid delivery system further displays, on the display screen, a first indication of receiving an excessive number of fluid delivery pump programming alerts associated with the first fluid identifier. The fluid delivery system adjusts a first fluid delivery limit setting associated with delivery of the first fluid in response to the excessive number of fluid delivery pump programming alerts associated with the first fluid identifier. The fluid delivery system implements the adjusted first fluid delivery limit setting for each of multiple fluid delivery pumps subsequently requesting to deliver the first fluid to a respective recipient.
