SelfDose™ Patient-Controlled Injector

Off-the-Shelf Delivery System

The SelfDose patient-controlled injector is an off-the-shelf delivery system that is ergonomically designed for optimal patient administration. Extensive human factors studies have been performed with the SelfDose injector, confirming the intuitive design, supporting ease of use and patient acceptance, and potentially minimizing the need for costly validation. 


The patient-controlled delivery rate of the SelfDose injector may help to minimize pain compared to spring-based auto-injectors.

  • Visual indicator to guide proper drug administration
  • Passive needle safety system that helps prevent needlestick injury
  • Needle depth can be customized to optimize drug absorption
