Abstract
Provided herein is a drug delivery device including a syringe barrel having a proximal end, a distal end, and a sidewall arranged between the proximal end and the distal end defining an interior configured to hold a composition, a plunger rod received at least partially within the interior of the syringe, the plunger rod having a proximal end, a distal end, and a stopper arranged at the distal end, and a sensor assembly, including a capacitive element and a short-range communication device in electrical communication with the capacitive element, wherein the short-range communication device is capable of measuring capacitance at the capacitive element.
Claims21
A drug delivery device comprising:
- a syringe barrel comprising a proximal end, a distal end, and a sidewall arranged between the proximal end and the distal end defining an interior configured to hold a composition;
- a plunger rod received at least partially within the interior of the syringe, the plunger rod comprising a proximal end, a distal end, and a stopper arranged at the distal end;
- and
- a sensor assembly, comprising:
- a capacitive element;
- and
- a short-range communication device in electrical communication with the capacitive element, wherein the short-range communication device is capable of measuring capacitance at the capacitive element;
- a displaceable needle shield;
- and
- a spring having a compressed configuration and an expanded configuration, the spring configured to displace the needle shield from a first, proximal position in which the displaceable needle shield does not surround a needle of the syringe to a second, distal position in which the displaceable needle shield at least partially surrounds the needle of the syringe,
- wherein the capacitive element is configured to detect a change in capacitance based on a change in state of the spring from the compressed configuration to the expanded configuration.
