Infusion Device Back-Mounted Pump Module Space Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infusion devices are not space-efficient, making them cumbersome for bedside use in hospitals, particularly in intensive care units where multiple devices are required.
Innovation Solution
The infusion device features a housing with the disposable pump module attached to its back side, allowing for a compact, flat design resembling a smartphone, and a pivotable back part for easy attachment and detachment of disposable modules, along with a built-in battery for autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the disposable pump module is attached to the front side of the housing, then the device structure is simple, but the device occupies more space and is less space-efficient
Solution Approach 1:
The disposable pump module is attached to the back side of the housing instead of the front side, utilizing the third dimension (depth/thickness) to achieve space efficiency. This allows the device to have a smaller footprint when placed on surfaces, enabling better organization and spacing in clinical environments.
2Area of stationary object
If the disposable pump module is attached to the back side of the housing, then space efficiency is improved, but the device complexity increases
Solution Approach 1:
The device is divided into modular components: a reusable housing containing the pump mechanism and a separate disposable pump module. This segmentation allows the disposable module to be attached to the back side of the housing, achieving space efficiency while maintaining operational simplicity through modular design.
3Adaptability or versatility
If multiple infusion devices are placed at the bedside, then patient care requirements are met, but space consumption increases
Solution Approach 1:
By attaching the disposable pump module to the back side of the housing, the device achieves a compact, space-efficient form factor. This allows multiple infusion devices to be placed at the bedside without excessive space consumption, while still meeting patient care requirements through the ability to provide multiple infusion services.
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 enables a space-saving, portable infusion device that can be easily positioned and operated without external power, facilitating efficient use in clinical settings.
Implementation Method 1
The pump mechanism in this infusion device comprises a wobble device constituted to perform a wobbling pump action for acting onto a membrane of a disposable pump module. By locally depressing the membrane in a revolving fashion, a liquid is pumped through a pump channel of the disposal pump module
Implementation Method 2
The back part is pivotable with respect to the housing when it is connected to the housing. To exchange the back part by another back part, the back part may be released from the housing such that it can be taken off the housing to connect another back part to the housing.

AI summary
An infusion device (1) comprises a housing (10) having a front side (102) and a back side (103) opposite to the front side (102). A display device (11) is arranged at the front side (102) of the housing (10). A pump mechanism (18) serves to act onto a disposable pump module (17, 4), the pump mechanism (18) being included in the housing (10). Herein, the housing (10) is constituted to receive the disposable pump module (17, 4) at the back side (103). In this way an infusion device is provided which allows placing a disposable pump module on the housing of the infusion device and which may offer space savings over existing infusion devices.
