Penetrable Absorber Container for Medical Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for gas absorption in medical device packaging are inefficient, requiring multiple pouches that increase material costs, waste, and complexity, while also leaving the outer surface of inner pouches non-sterile.
Innovation Solution
An absorber device with a container and a movable penetration device that penetrates a contact section on the package wall, allowing fluid from the package to be absorbed by an absorber within the container, which is gas-tightly packed for efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate gas-permeable pouches are used for absorption, then gas absorption function is achieved, but material costs and packaging complexity increase
Solution Approach 1:
The patent combines the absorber component and the package into a single integrated unit. The absorber is placed inside the package and connected to the package wall through a penetration element, eliminating the need for separate inner and outer pouches while maintaining the gas absorption function.
Solution Approach 2:
The package wall serves multiple functions: it contains the medical device, provides structural integrity, and allows gas permeation to the absorber through the penetration element. This multi-functionality reduces the need for additional specialized components.
2Reliability
If two separate pouches are used for absorption, then gas absorption function is achieved, but material costs and waste increase
Solution Approach 1:
The patent combines the absorber component and the package into a single integrated unit. The absorber is placed inside the package and connected to the package wall through a penetration element, eliminating the need for separate inner and outer pouches while maintaining the gas absorption function.
3Ease of operation
If a two-chamber pouch design is used, then absorber can be added after sterilisation, but material costs and waste increase due to complex pouch design
Solution Approach 1:
The penetration element is pre-installed in the package wall during manufacturing, creating a predetermined access path. This allows the absorber to be easily inserted after sterilisation without requiring complex pouch designs or post-sterilisation pouch opening.
Solution Approach 2:
The package is divided into functional zones: a sterile inner space containing the medical device, and an outer region with the absorber. The penetration element creates a controlled interface between these zones, allowing gas exchange while maintaining sterility.
4Reliability
If standardised absorber components with two pouches are used, then gas absorption is achieved, but user-friendliness decreases due to opening two pouches
Solution Approach 1:
The patent combines the absorber component and the package into a single integrated unit. The absorber is placed inside the package and connected to the package wall through a penetration element, eliminating the need for separate inner and outer pouches while maintaining the gas absorption function.
5Reliability
If two pouches are used for absorption, then gas absorption function is achieved, but storage volume increases
Solution Approach 1:
The patent combines the absorber component and the package into a single integrated unit. The absorber is placed inside the package and connected to the package wall through a penetration element, eliminating the need for separate inner and outer pouches while maintaining the gas absorption function.
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

AI summary
The invention is related to an absorber device (1) for absorbing a fluid (131) residing in an inner space (120) enclosed by a package (100) of a medical device (132), the package (100) comprising a wall (110) enclosing the inner space (120) of the package (100). The absorber device (1) comprises a container (10), wherein the container (10) comprises a wall (12) enclosing an inner space (14) of the container (10), wherein the wall (12) comprises a contact section (20), wherein the contact section (20) is configured to be penetrated. The absorber device (1) comprises an absorber (30) arranged in the inner space (14) of the container (10), and a movable penetration device (40), wherein the penetration device (40) is configured to be moved from a first position to a second position. In the first position, the penetration device (40) is positioned in the inner space (14) of the container (10). In the second position, the penetration device (40) is configured to penetrate the contact section (20) and the wall (110) of the package (100), when the contact section (20) is arranged on an outer surface (140) of the wall (110) of the package (100), such that the inner space (14) of the container (10) is fluidically connected to the inner space (120) of the package (100) to thereby allow fluid (131) from the inner space (120) of the package (100) to pass to the inner space (14) of the container (10) and be absorbed by the absorber (30).
