Medical Device Package With Segmented Recess And Breakable Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing medical device packaging requires users to peel off a lid from the main body to access the device, making the retrieval process complicated and risking the device's fall due to the entire recess portion being opened.
Innovation Solution
A medical device package with a packaging container featuring a take-out recess portion adjacent to the holding recess and a sealing film with an unsealing assistance portion that allows the user to break and open only a part of the sealing film, enabling the device to be removed without peeling off the lid from the main body, thus preventing accidental falls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is peeled off from the main body to take out the medical device, then the medical device can be accessed, but the operation becomes complicated and the medical device may fall from the opened recess portion
Solution Approach 1:
The packaging container is divided into a main body and a separate lid that can be easily separated. The recess portion is segmented into a holding area and a take-out area, allowing the lid to be peeled off cleanly without disturbing the medical device in its holding position, thus simplifying the retrieval operation while preventing device fall.
2Ease of operation
If the lid is peeled off from the main body to take out the medical device, then the medical device can be accessed, but the entire recess portion is opened causing potential device fall
Solution Approach 1:
The recess portion is divided into a holding recess where the medical device remains secured and a take-out recess that opens when the lid is removed. This segmentation allows the device to stay stable in its holding position while the take-out area provides access, thus maintaining device stability during retrieval operations.
Solution Approach 2:
The take-out recess portion acts as an intermediary space between the sealed holding recess and the external environment. When the lid is peeled off, this intermediate area allows controlled access to the device without fully exposing the holding recess, preventing accidental device fall while enabling retrieval.
3Reliability
If the sealing film is broken at a specific position through the unsealing assistance portion, then only a part of the sealing film is opened preventing device fall, but the breaking mechanism must be designed
Solution Approach 1:
The unsealing assistance portion is pre-formed on the sealing film during manufacturing, creating a predetermined breaking point. This preliminary action eliminates the need for complex breaking mechanisms during use, as the user simply needs to apply minimal force at the pre-designed location to break the sealing film partially, thus maintaining device stability without significantly increasing manufacturing complexity.
Solution Approach 2:
The sealing film's structural parameters are modified at the unsealing assistance portion to create a weak point with lower breaking strength. This parameter change allows the sealing film to break easily at a specific location when minimal force is applied, enabling partial opening that prevents device fall while keeping the manufacturing process relatively simple through standard film formation techniques.

AI summary
A medical device package includes a container main body and a sealing film that covers and seals a recess portion of the container main body. A medical device is held in the recess portion of the container main body. The sealing film includes an unsealing assistance portion for facilitating breakage of a part of the sealing film. At least a part of the unsealing assistance portion faces a take-out recess portion of the container main body.
