Functional Use: This device is a small lever that hooks under the ring-pull tab on food or drink cans and lifts it, so a person can start the tab without needing to get a fingertip under it.
Relevant Occupations: Feeding and Eating, Meal Preparation
Client Factors: May be relevant when pinch strength or finger range of motion is reduced.
Performance Skills: The client steadies the can with one hand, slides the tip under the tab, then lifts, which replaces pinching and pulling the tab by hand.
Safety Considerations: The lid edge is sharp, so keep fingers clear of the opened edge. Seat the tip fully under the tab before pulling.
Limitations: The person still needs enough wrist and arm range of motion to work the lever, and the tip can wear down with use. It is not a cleared medical device, so its use must be a clinical decision made by the treating occupational therapist.

Issues: Depending on the slicer and printer, the can opener tip may require supports.
Recommendations: None
Ease of use: Easy
Test results or review: The part worked as intended.
