Integrated Gas Canister Assembly for Self-Powered Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices require an external power source for energy, which can be inconvenient and may limit their usability.
Innovation Solution
A single-use gas canister is integrated into medical devices, containing pressurized or liquefied gas, with a septum that is punctured by a pin to release energy for device operation, allowing for self-contained energy provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an external power source is used for medical devices, then energy can be supplied, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts the power source from the external environment and integrates it directly into the medical device as a self-contained gas canister. This eliminates the need for external power connections while providing the necessary energy for device operation.
Solution Approach 2:
The patent employs a single-use gas canister that is disposed of after one use. This disposable approach simplifies the device design by eliminating complex power management systems and ensures reliable energy supply for the specific procedure without requiring recharging or maintenance.
2Use of energy by moving object
If an external power source is used for medical devices, then energy can be supplied, but ease of operation worsens
Solution Approach 1:
The patent removes the dependency on external power sources by incorporating a self-contained gas canister directly into the medical device. This integration eliminates the need for external connections and simplifies the operation to a simple activation process.
Solution Approach 2:
The medical device becomes self-sufficient with the integrated gas canister that provides its own power source. The device activates the gas canister through a simple mechanism, eliminating the need for external power supply operations and improving ease of use.
3Quantity of substance
If a septum is used to seal the gas canister, then gas containment is improved, but reliability worsens due to potential failure
Solution Approach 1:
The patent uses a disposable septum that is part of the single-use gas canister assembly. This eliminates the need for complex sealing mechanisms and ensures reliable gas containment during the procedure, with the entire assembly being discarded after use to prevent any potential long-term reliability issues.
Solution Approach 2:
The septum is pre-installed and sealed onto the gas canister before use. This preliminary sealing action ensures gas containment is established before the procedure begins, eliminating the need for complex sealing operations during use and improving reliability.

AI summary
Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.
