1. A dose monitoring device configured to mate with a syringe having a plunger that is slidably engaged in a barrel of the syringe, comprising:
- a first channel configured to receive a syringe body of the syringe;
one or more motion sensors in contact with a rod of the plunger and configured to detect movement of the plunger into or out of the barrel of the syringe body;
one or more orientation sensors configured to detect upward and downward orientations of the syringe; and
a communication module configured to transmit data to an external device from the one or more motion sensors and the one or more orientation sensors.

14. A method for recording the injection time and the amount of liquid injected by a syringe, comprising:
-
providing a syringe having a plunger that is slidably engaged in a barrel of the syringe, wherein the syringe is configured to administer a medicament; providing a dose monitoring device comprising one or more plunger sensors and one or more orientation sensors; detecting a movement event by monitoring the orientation sensor to detect upward and downward orientations of the syringe; detecting an injection event by monitoring the plunger sensor to detect movement of the plunger into or out of the barrel of the syringe; and transmitting data from the one or more plunger sensors and the one or more orientation sensors based on the detected movement event or injection event to an external device. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
