Wearable Bolus Injector
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
- Completion feedback concept
- Device design intended to simplify user interaction
Development status. The Wearable Bolus Injector is a device concept in development. It is not approved, certified or commercially available.

Hands-Free Autoinjector
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.
