Osmotic WBI Technology

Utilizing a strong force of nature

For injection of larger pharmaceutical volumes subcutaneously, a low flow rate is needed in order for the tissue to absorb the volume injected. In order to achieve this, complex and expensive drive mechanisms with batteries and electronics are commonly used in larger volume, on-body injectors.

The Subcuject WBI utilizes forward osmosis technology to generate force. In simplified terms, two chambers of liquid are separated by a semipermeable membrane. Adding salt to one chamber draws in liquid from the other chamber and hydraulic/mechanical pressure for driving the plunger in the primary drug container is generated. Simple and at a low cost.

Osmosis is a basic and strong force of nature.

Pending patents cover core and peripheral functionality.

Osmotic WBI Value Proposition

  • Few parts
  • No moving parts
  • No electronics

  • Standard primary packaging materials
  • Glass cartridge with septum
  • Standard plunger compound

  • Compared with electromechanical wearables
  • Salt and water
  • No electronics or batteries to dispose

Hands-free Autoinjector value proposition

Alternative to conventional handheld autoinjectors

  • Few parts

  • Standard primary packaging materials
  • Glass cartridge with septum
  • Standard plunger compound
  • No excessive force on drug


  • Osmotic WBI
    • Ready for drug specific development
    • The current version can deliver up to 5 ml
    • Can be developed for higher volumes
  • Hands-Free Autoinjector
    • Ready for drug specific development
    • The current version can deliver up to 3 ml
    • Can be developed for higher volumes (5 ml) or for lower volumes (<1 ml)


  • Many new biologics are in development by pharma companies
  • There is a trend towards less frequent drug administration and patient self administration of injections at home
  • This is driving a new class of injectors: wearable bolus injectors (WBI) – also called on-body injectors (OBI) or large volume injectors (LVI)
  • Subcuject is developing a simple WBI injector, using osmosis (salt and water) as the driving engine
  • As an alternative to conventional hand-held autoinjectors, Subcuject is also developing a Hands-Free Autoinjector which is driven by a spring
