Pretensioned Clamping Membrane for Sterile Medical Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing membrane packaging technologies are inadequate for sterile protection of medical objects, as they lack sufficient tightness and cannot securely hold heavy or sterile items due to peripheral sealing issues.
Innovation Solution
A container with a single clamping membrane that is peripherally attached to one container part, which is pretensioned upon closure, forming a circumferential sealing edge and using additional holding devices to securely fix the object, ensuring absolute sealing and secure holding of medical objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two membranes are used opposite each other for clamping, then the object can be held, but the packaging lacks sufficient tightness and cannot securely hold heavy or sterile items
Solution Approach 1:
The patent removes one of the two membranes from the traditional configuration, leaving only a single membrane that is peripherally attached to one container part. This simplification allows the single membrane to be pretensioned upon closure, creating a reliable sealing surface against the other container part without the complexity of coordinating two membranes.
Solution Approach 2:
The patent divides the sealing function into two distinct components: the single clamping membrane attached to one part, and the peripheral sealing edge formed at the junction of the two container parts. This segmentation allows each component to optimize its function - the membrane provides clamping and the sealing edge provides the tight seal.
2Reliability
If membranes are pretensioned to hold objects, then holding capability is improved, but sterile protection and long-term storage are not achieved
Solution Approach 1:
The patent applies preliminary action by pretensioning the single clamping membrane upon closure of the container. This preliminary tensioning creates a reliable sealing surface that maintains sterile protection throughout the entire storage duration, eliminating the need for complex multi-membrane systems that would be required to maintain sterility over time.
Solution Approach 2:
The container closure mechanism itself performs the sealing function through the interaction of the pretensioned membrane with the peripheral sealing edge. The system is self-sufficient, requiring no additional sterile barriers or complex sealing mechanisms beyond the basic container closure.
3Device complexity
If a single clamping membrane is used, then packaging simplicity is improved, but secure holding of heavy objects is not achieved
Solution Approach 1:
The patent employs dynamics by making the single clamping membrane pretensionable upon closure. This dynamic tensioning allows the membrane to adapt to the object being packaged, providing secure holding capability for heavy objects through the force of the pretensioned membrane against the container wall, rather than relying on a static membrane configuration.
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
The solution enables the secure and long-term storage of sterile medical objects by creating a double sealing effect with radially spaced sealing edges, ensuring the integrity of the packaging over time.
Implementation Method 1
an additional pretensioning is applicable to the clamping membrane upon closing of the container, in that the object to be protected pushes the clamping membrane into the interior of the container part
Implementation Method 2
a clamping membrane is circumferentially and peripherally attached to at least one container part

AI summary
Container with a membrane packaging for medical objects, consisting of at least one cover which is connectable to a lower part, wherein at least one clamping membrane is circumferentially and peripherally attached to at least one container part, and the object to be protected lies upon the at least one clamping membrane and is borne by it, wherein only one clamping membrane, is given, which lies opposite to a fixed holding slot for holding the object on the other container part and an additional pretensioning can be applied to the clamping membrane upon closing of the container.
