Latest Patents

Yeh’s listed patent, “Feedback mechanisms,” describes a notification mechanism positioned inside a medical device’s housing. A rear cap is secured to the distal end of the housing and includes a hollow tubular structure that extends proximally, remains fixed relative to the housing, and runs parallel to its longitudinal axis.

A rotator is positioned around the tubular structure and can turn between two positions. The second position corresponds with the start of medicament delivery. As the rotator moves, its contact surface engages with and then disengages from a corresponding surface on the rear cap or the inside of the device housing. This arrangement provides a mechanical indication that dose delivery has begun.
