Elastomer Diaphragm Actuation
Gas pressure expands the internal elastomer diaphragm to drive controlled reservoir displacement.
HEED® uses gas-pressure-driven elastomer expansion to create controlled reservoir displacement in a compact wearable format.
The expanding diaphragm supports steady delivery force, simplified mechanics, and pressure-adaptive biologic administration.
First elastomer prototype
Elastomer diaphragm expansion inside the reservoir wall under gas pressure.
As gas pressure expands the internal elastomer diaphragm, it fills the reservoir volume and drives the medication forward through the delivery path.
This controlled displacement supports complete reservoir emptying and consistent dose delivery.
The result is a compact actuation system designed to reduce residual volume and improve delivery efficiency.
Elastomer stretching
Elastomer diaphragm positioned inside the reservoir before pressurisation.
Expanded diaphragm demonstrates controlled displacement for medication delivery.
Gas pressure begins expanding the elastomer diaphragm against the reservoir wall.
