Functional Use: This device is a larger pull-tab aid that slides under the ring on bigger food cans and lifts the lid, keeping fingers away from the sharp edge.
Relevant Occupations: Meal Preparation
Client Factors: May be relevant when grip and pinch strength are reduced.
Performance Skills: One hand holds the can while the other works the device under the ring and levers the lid up, instead of pinching and pulling the tab.
Safety Considerations: The opened lid edge is sharp, so keep fingers clear during and after the lift. Seat the tool fully under the ring before use.
Limitations: It is made for food cans, not beverage cans. The center can wear with use. It is not a cleared medical device, so its use must be a clinical decision made by the treating occupational therapist.
-
Issues: None
Recommendations: Check the type of cans the user plans to open. This can opener works well for food cans but not for beverage cans.
Ease of use: Easy
Test results or review: The part worked as intended. The center of the piece may wear down with extended use.
