Auto Injector

For long-term but intermittent dose regimens, drug therapy patients require small, discreet, and reliable injection devices that can be taken with them as they go about their day. Because high viscosity drugs or large volume injections require either a high force to be applied or long injection times, motorized auto-injectors are often preferred over manual syringes.

Portescap's high power density motors and linear motion assemblies help reduce the size of the auto-injector while maintaining high force for faster injection times or smaller diameter and less painful needles. Portescap's low noise gearboxes also improve discretion while administering a dose in public settings. Their high efficiency also provides greater freedom by increasing battery life or further reducing size by shrinking the battery.
