Pump Clip With Biasing Lock Prevents Infusion Device Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable fluid infusion devices, such as insulin pumps, are susceptible to accidental displacement, which can cause damage and affect the delivery of medication, leading to reduced efficacy of infusion therapy.
Innovation Solution
A pump clip designed to securely couple the fluid infusion device to the user, featuring a clip base with a biasing member and a lock button, allowing for secure attachment to clothing or objects, and capable of withstanding torques and forces without damaging the device or infusion set.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pump clip is secured to the user's clothing to enable easy access and secure positioning, then the device can be conveniently carried, but the fluid infusion device becomes susceptible to accidental displacement from bumping or snagging
Solution Approach 1:
The pump clip incorporates a movable disengagement mechanism where the clip can transition between a locked engaged state and a released state. The biasing member continuously applies force to maintain engagement, but a actuating force can overcome this biasing to deliberately disengage. This dynamic design allows the clip to remain securely attached during normal activity while enabling intentional removal when needed.
2Reliability
If the pump clip is made secure to withstand forces, then accidental displacement is prevented, but the device complexity increases with additional components like biasing members and lock mechanisms
Solution Approach 1:
The pump clip integrates multiple functions into a unified structure: the clip body provides mechanical attachment, the biasing member provides continuous engagement force, and the actuating mechanism provides controlled disengagement. These elements work together as a single integrated assembly rather than separate components, achieving secure attachment with deliberate release capability while maintaining reasonable structural simplicity.
3Reliability
If the pump clip uses a biasing member to maintain engagement, then the device remains securely attached, but the complexity of the coupling mechanism increases
Solution Approach 1:
The biasing member is configured to automatically maintain engagement between the pump clip and the fluid infusion device without requiring active control or additional power sources. The spring-loaded or elastomeric biasing element continuously applies force to keep the clip engaged, and the geometry of the coupling surfaces ensures that normal use forces naturally maintain the engaged state, with disengagement requiring a deliberate actuating motion.

AI summary
A pump clip for a fluid infusion device is provided. The pump clip includes a clip base having a first end opposite a second end. The clip base defines an aperture through the clip base between the first end and the second end. The clip base is pivotable between a first position and a second position along a first pivot axis. The pump clip includes a clip pivot base coupled to the clip base along the first pivot axis. At least a portion of the clip pivot base is received within the aperture in the first position. The pump clip includes a clip coupled to the clip pivot base along a second pivot axis and the clip cooperates with the clip pivot base to receive an article.
