Container Adapter Unlock Mechanism for Medical Delivery Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container adapters for medical delivery devices lack a mechanism to ensure the lock mechanism is only activated when a container is properly held, leading to potential dosing inaccuracies and safety issues, as they can be operated without a container being present or properly seated.
Innovation Solution
A container adapter with an unlock mechanism that activates the medical delivery device's lock mechanism only when a container is correctly positioned, featuring an activation member that moves to engage the lock mechanism upon proper container seating, preventing operation if the container is not properly held.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a container adapter is used to enable operation of the medical delivery device, then the device can be operated with a container properly held, but the lock mechanism may be activated even when no container is present, leading to safety issues
Solution Approach 1:
The activation member provides feedback about the container's presence and proper positioning to the lock mechanism. When the container is properly held in the adapter container seat, the activation member is in the activating position, which signals the lock mechanism to allow operation. This feedback loop ensures that the device only operates when the container is correctly positioned.
Solution Approach 2:
The activation member acts as an intermediary between the container and the lock mechanism. It translates the physical state of container positioning into a mechanical signal that controls the lock mechanism. This intermediary component ensures that the lock mechanism is activated only when the container is properly held, preventing premature or incorrect operation.
2Productivity
If the lock mechanism is always activated when the adapter is positioned, then operation is always allowed, but dosing accuracy is compromised when no container is present
Solution Approach 1:
The activation member continuously provides feedback about container presence to the lock mechanism. When no container is present or the container is improperly positioned, the activation member remains in the non-activating position, preventing the lock mechanism from allowing operation. This ensures dosing accuracy by blocking operation unless the container is correctly positioned.
Solution Approach 2:
The system automatically controls the lock mechanism based on the container's positioning state without requiring external intervention. The activation member self-activates or self-deactivates the lock mechanism depending on whether the container is properly held, ensuring dosing accuracy is maintained automatically.
3Ease of operation
If the activation member is always in the activating position, then the lock mechanism is always unlocked, but safety is compromised allowing operation without proper container positioning
Solution Approach 1:
The activation member provides real-time feedback about container positioning to the lock mechanism. It only moves to the activating position when the container is properly held in the adapter container seat, ensuring that the lock mechanism remains locked and prevents operation when the container is absent or improperly positioned.
Solution Approach 2:
The activation member serves as a safety intermediary that controls access to the operational state. It physically connects the container positioning state to the lock mechanism, ensuring that operation is only permitted when the container is correctly positioned, thereby preventing improper operation.

AI summary
A container adapter (1) for a medical delivery device, which medical delivery device has a container seat for holding a container in a predefined position, a dosage chamber, a dosing mechanism to transfer a liquid from the container held in the container seat to the dosage chamber and a lock mechanism adapted to prevent operation of the dosing mechanism when no container is held in the container seat and to allow operation of the dosing mechanism when the container is held in the container seat. The container adapter (1) comprises an adapter container seat (11), a joint structure (12) and an unlock mechanism. The adapter container seat (11) is configured to hold a container in a predefined position. The joint structure (12) is configured to be detachably positioned in the container seat of the medical delivery device and to connect the adapter container seat (11) to the dosing mechanism of the medical delivery device (3) when the joint structure (12) is positioned in the container seat of the medical delivery device (3). The unlock mechanism is configured to activate the lock mechanism of the medical delivery device when the joint structure (12) is positioned in the container seat of the medical delivery device and the container is properly held in the adapter container seat (11), and to prevent activation of the lock mechanism of the medical delivery device when the container is not properly held in the adapter container seat (11).
