Abstract
An active injection guide concurrently monitors surface contact and an instantaneous contact force along an injection axis of an injector in order to ensure that the injector is properly positioned on a patient before an injection can be initiated.
Claims20
An active injection guide comprising:
- an injector having an injection axis;
- a contact surface configured to be placed on a target surface for an injection from the injector;
- a sensor arrangement including three or more sensors coupled to the contact surface and spaced around the injection axis, each of the three or more sensors configured to measure a contact force against the target surface along the injection axis;
- and
- a controller configured to generate a concurrent measurement of an orientation of the injector relative to the target surface and a force against the target surface along the injection axis based on the measurements from the three or more sensors, and to prevent activation of the injector until the measurement of the orientation and the force are each within predetermined ranges suitable for injection.
