Peristaltic Infusion Pump Door and Line Orientation Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infusion apparatuses face challenges in easy door detachment for cleaning, correct infusion line orientation, and simultaneous administration of multiple medical fluids, with existing solutions not fully addressing these issues effectively.
Innovation Solution
The infusion apparatus features a removable door with a journal and bearing arrangement for easy cleaning, color-coded fittings for correct line orientation, and a docking station with electronic processing and visual alarms for managing multiple pumps and alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door is made permanently fixed to the housing, then the structural integrity and reliability are improved, but the ease of operation for cleaning purposes deteriorates
Solution Approach 1:
The door assembly is segmented into separable components connected by a hinge mechanism with detent engagement. The door can be divided into removable and fixed portions, allowing the removable part to be detached for cleaning while the main structure remains intact. This segmentation enables the door to function as a unified structure during operation while allowing partial disassembly for maintenance.
2Ease of operation
If the infusion line orientation is not color-coded, then the device complexity is reduced, but the ease of operation for correct line insertion deteriorates
Solution Approach 1:
Color-coded indicators are applied to the infusion line connectors and corresponding receptacles to provide visual guidance for correct orientation. Different colors mark the proximal and distal ends of the infusion line, allowing operators to quickly identify the correct insertion direction without complex mechanical guides or additional components.
3Productivity
If multiple pumps are managed independently, then the device complexity is reduced, but the productivity for simultaneous infusion deteriorates
Solution Approach 1:
Multiple infusion pumps are merged into a single centralized docking station that provides unified power supply, control, and monitoring functions. The docking station integrates multiple pump units, allowing them to operate simultaneously while sharing common resources such as power connections, alarm systems, and control interfaces. This consolidation enables efficient management of multiple infusions without requiring separate standalone units for each pump.
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
Facilitates straightforward door removal and replacement, ensures correct infusion line orientation through color coding, and effectively manages multiple pumps and alarms in a centralized system, enhancing operational efficiency and safety.
Implementation Method 1
a peristaltic pump in which a flexible resilient tube, forming part of a fluid delivery line for delivering a medical fluid to a patient is located between, on the one hand, a peristaltic assembly, for example, an array of displaceable fingers, and, on the other hand, a counter surface or anvil, said tube, in use of the apparatus, being repeatedly pressed against the anvil or counter surface, by said peristaltic assembly, at different positions along the flexible resilient tube in a predetermined sequence, to provide a peristaltic pumping action

AI summary
In a peristaltic medical infusion pump unit, comprising a peristaltic assembly and a counter surface or anvil facing said peristaltic assembly and provided by the inner surface of a door (30) pivotally mounted on a housing (12) of the unit, the door (30) is readily non-destructively removable and replaceable. In use of the peristaltic pump unit, a flexible resilient tube (36) forming part of a medical fluid delivery line is extended between the peristaltic assembly and the counter surface or anvil provided by the door. The medical is fluid delivery line has first and second colour coded fittings (38, 40) spaced therealong upstream and downstream of the peristaltic assembly (26) and the region of the housing of the pump unit across which the infusion line is extended is provided, correspondingly spaced above and below the peristaltic assembly (26) with correspondingly colour coded support means (22, 24) for these fittings.
