US Patent 11957542 Sensing complete injection for animal injection device

A semi-automated veterinary medicine delivery device may sense whether and how much air may have been incorporated into a dose delivered to an animal. The device may also sense an incomplete injection in some cases, and may cause a second dose to be administered to make up for the incomplete dose. The device may compare a position sensor on a syringe in combination with a current sensor on a motor attached to the syringe to detect any abnormalities. In the case of an improper dose, the device may alert the user and administer a second dose.
