Devices

Two hands‑free device concepts.

A skin-adhered autoinjector and a wearable bolus injector, both built on the same principle: activate once, and the device completes the injection.

Hands-Free Autoinjector

Device concept

A skin-adhered injection device concept designed to carry out the injection automatically once it has been activated — so the user does not need to hold the device in place while the dose is delivered.

Design concept: The device is applied to the skin, activated, and then completes its injection sequence on its own: needle insertion, drug delivery, completion feedback and needle retraction.
Key features: Skin-adhered device design
Hands-free operation after activation
Automatic injection sequence
Needle insertion and retraction concept

Wearable Bolus Injector

Device concept

A wearable injection-device concept intended for subcutaneous drug delivery. The device is worn on the body during the injection, removing the need to hold an injector in position.

Wearable design concept: The wearable bolus injector (WBI) concept is designed to adhere to the skin and deliver a bolus dose subcutaneously through an automatic, mechanically driven sequence.
Key features: Wearable, skin-adhered form factor
Subcutaneous bolus delivery concept
Automatic injection sequence after activation
Needle insertion and retraction concept

02Status definitions

Concept, prototype, demonstration device — what we mean.

We use these terms consistently across the site so that the status of each device is clear.

Concept

A defined device principle and design intent.

Prototype

A functional build used to develop and test the mechanism.

Demonstration device

A build made to show how the concept works to partners.

Commercially available

Approved and on the market. Neither concept is at this stage.
