Sterile Medical Device Packaging with Manual Grip Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging systems for medical devices are often bulky, expensive, and difficult to open, and lack mechanisms to prevent contamination after opening, leading to potential sterility issues during surgical use.
Innovation Solution
A packaging assembly comprising multiple components that create a sealed environment with retention features allowing manual gripping and detachment, enabling sterile medical devices to be accessed without direct contact, maintaining sterility until use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hermetic seal packaging is used to maintain sterility, then the medical device remains sterile, but the packaging becomes bulky, heavy, and difficult to open
Solution Approach 1:
The packaging assembly is divided into multiple components: a rigid outer packaging component providing structural integrity and sterility, a flexible intermediate sealing component that can be easily manipulated, and a removable inner component. This segmentation allows each component to be optimized for its specific function while collectively solving both sterility maintenance and ease of opening.
Solution Approach 2:
The packaging incorporates dynamic elements such as flexible seals that can transition from a sealed state to an open state through controlled deformation. The flexible intermediate component allows the packaging to adapt during opening, reducing the force required while maintaining the hermetic seal until intentionally opened.
2Ease of operation
If packaging is opened outside the sterile field, then access is easy, but the medical device may be contaminated by practitioner contact
Solution Approach 1:
The packaging design includes an intermediary transfer mechanism where the medical device can be moved from the sealed packaging into a sterile container or drape without direct hand contact. This intermediary step acts as a buffer, allowing the device to be transferred while maintaining sterility barriers between the non-sterile practitioner hands and the sterile device.
Solution Approach 2:
The packaging is designed to be opened and the device accessed in a sequence that prepares the sterile field beforehand. The opening mechanism allows the practitioner to expose the device to air first, then use sterile techniques or sterile barriers to complete the transfer, ensuring sterility is maintained during the critical transfer phase.
3Ease of operation
If manual gripping of the medical device is required after opening, then handling is possible, but sterility is compromised by direct contact
Solution Approach 1:
The packaging contains nested components where an inner sterile barrier or container is housed within the outer packaging. When opened, the device remains within this nested sterile environment, allowing the practitioner to grip and manipulate the outer packaging or inner container without directly touching the sterile device itself.
Solution Approach 2:
A sterile barrier such as a drape, glove, or sterile container serves as an intermediary between the practitioner's hands and the medical device. This intermediary allows mechanical manipulation and gripping forces to be transmitted to the device while preventing direct contact that would compromise sterility.
4Reliability
If existing packaging mechanisms are used, then sterility is maintained, but the packaging lacks user-friendly retention features for safe and easy opening
Solution Approach 1:
The packaging incorporates localized retention features such as tabs, flaps, or rupture points at specific locations on the packaging assembly. These local features are designed to concentrate opening forces at predetermined weak points, making the packaging easy to open without compromising the overall hermetic seal integrity until intentionally breached.
Solution Approach 2:
The packaging material properties are varied at different locations to create easy-open features. For example, certain areas have reduced thickness, different material composition, or pre-scored lines that change the mechanical parameters of the packaging, allowing controlled opening with minimal force while maintaining seal integrity elsewhere.

AI summary
A packaging assembly may retain a sterile medical device for use in a surgical setting, such as an orthopedic implant or instrument. The packaging assembly may have a first packaging component and a second packaging component. The first packaging component and the second packaging component may be attachable to each other to define a first interior space containing the medical device. The first packaging component may have a first retention feature that defines a first interior receptacle shaped to receive at least part of the medical device such that a user can manually grip the medical device through the first retention feature. The first interior space may be manually opened by a user grasping the medical device through the first retention feature.
