Ambulatory Infusion Pump Battery Compartment Flex Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambulatory infusion pumps require improved power delivery systems to ensure continuous and reliable operation while mobile, as they need a portable power source to deliver vital medications and nutrition effectively.
Innovation Solution
The ambulatory pump features a battery compartment that can accommodate both household batteries and a battery pack, utilizing a flex guide that changes state to optimize the use of space, allowing for efficient installation and secure positioning of either power source, ensuring stable power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the battery compartment is designed to accommodate only one type of power source, then the design is simple, but the adaptability is reduced
Solution Approach 1:
The battery compartment is designed to accept multiple types of power sources (battery pack with connector and individual household batteries) through a universal interface. The compartment structure includes a recessed area that can accommodate different battery configurations, and the electrical connector is designed to work with both power source types, enabling the pump to function with various power sources without requiring separate compartments for each type.
2Power
If the battery compartment is designed for larger battery packs, then power delivery capability is improved, but the ease of operation for inserting smaller batteries becomes difficult
Solution Approach 1:
The battery compartment is segmented into different zones: a main recessed area for accommodating larger battery packs and smaller spaces for individual household batteries. The electrical connector is also segmented with contact points arranged to work with both power source types. This segmentation allows the compartment to provide adequate space for high-capacity battery packs while still allowing easy insertion and removal of smaller household batteries through the same interface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the ambulatory pump's power delivery capabilities, allowing for reliable operation over extended periods by accommodating different power sources, ensuring continuous delivery of medications and nutrition to patients.
Implementation Method 1
The flex guide has a compressed state and a non-compressed state where a profile of the flex guide has a height that is greater than half the insertion depth in the non-compressed state and that is less than half the insertion depth in the compressed state

AI summary
An ambulatory pump and a battery compartment for use in an ambulatory pump. The ambulatory pump includes a pump, a controller coupled to the pump for controlling the pump to deliver fluid to a patient, and a battery compartment electrically coupled to the pump and the controller. The battery compartment defines a cavity for alternately receiving a battery pack and a plurality of household batteries. A flex guide is positioned within the cavity. The flex guide has a compressed state and a non-compressed state where a profile of the flex guide has a height that is greater than half the insertion depth of the household batteries in the non-compressed state and that is less than half the insertion depth in the compressed state.
