Medication Delivery Device Packaging for Moisture and Actuation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medication administration devices, particularly those delivering glucagon, are susceptible to premature actuation and degradation during storage and transport, which compromises their efficacy and safety.
Innovation Solution
A medication delivery system comprising a medication administration device, a container, and a cap that forms a hermetic seal, with hold down members preventing premature actuation and a desiccant to maintain moisture control, ensuring the device and medication remain viable until use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the medication administration device is stored in an open container, then it is easily accessible, but the medication is exposed to moisture and premature actuation
Solution Approach 1:
The medication administration device is nested within a container that provides protective enclosure. The device fits inside the container cavity, which is then sealed with a cap, creating a nested structure that protects the medication from environmental factors while maintaining a compact form factor.
Solution Approach 2:
The container with sealed cap creates a protected environment that isolates the medication from external moisture and contaminants. This sealed environment acts as a barrier that prevents degradation of the medication properties during storage and transport.
2Reliability
If the container is sealed tightly to protect medication, then medication integrity is maintained, but the device cannot be quickly removed for use
Solution Approach 1:
The container is divided into separable components: the container body and the removable cap. This segmentation allows the cap to be easily detached from the container body, enabling quick access to the medication administration device while maintaining secure sealing when the cap is attached.
Solution Approach 2:
The hold down members are pre-positioned within the container structure to automatically engage with the device when inserted, ensuring proper positioning and sealing without requiring additional user actions. This preliminary arrangement enables rapid deployment of the device when needed.
3Reliability
If hold down members are added to prevent device movement, then premature actuation is prevented, but device complexity increases
Solution Approach 1:
Hold down members are strategically positioned at specific locations within the container where they provide maximum restraint with minimum structural complexity. These localized elements address the specific problem of device movement without requiring comprehensive reinforcement of the entire container structure.
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 system maintains the integrity and functionality of the medication and its delivery device by preventing premature discharge and protecting against moisture, ensuring quick and easy use when needed.
Implementation Method 1
a cap to seal the medication administration device within the container... the cap is secured to the container in the closed position to form a hermetic sealing of the medication administration device within the cavity
Implementation Method 2
a desiccant to maintain moisture control

AI summary
The present disclosure relates to a medication delivery system including a medication administration device, a medication within the medication administration device, a container defining a cavity receiving the medication administration device, and a cap attached to the container and sealing the medication administration device within the cavity. The medication administration device includes an actuator extending from a body and operable to expel the medication by depressing the actuator into the body. The cap includes hold down members positioned to bear against the body of the medication administration device to prevent movement of the medication administration device toward the cap beyond a predetermined distance. The medication administration device is thereby prevented, inter alia, from prematurely discharging the medication during storage and transport.
