Abstract: An apparatus for presenting an application status of a medical device that has a unused state and a used state. The apparatus includes a label having an electrochromic element. The label is at least partially disposed on an exterior surface of the medical device and is configured to display a predetermined feature in response to an electric current. A power source is disposed in or on the medical device for providing the electric current. A switch is configured to selectively connect or disconnect the label and the power source to one another for controlling the application of the electric current to the electrochromic element in response to actuation of the medical device from the unused state to the used state. The label may be scanned by a scan device that may connect to a medical organization for communicating information between the scan device and the medical organization.

Abstract: A syringe includes a plunger having multiple sections of differing diameters or materials, and a barrel with a cavity into which the plunger is inserted. The barrel includes a first probe and a second probe opposite to one another such that an interior volume of the barrel is radially between the first and second probes. A microcontroller is configured to measure a capacitance between the first and second probes, with the measured capacitance having a first capacitance value when the first section of the plunger shaft is between the first and second probes and a second capacitance value different from the first capacitance value when a second section of the plunger shaft is between the first and second probes. The microcontroller is configured to determine that an injection has been completed when the second capacitance value is measured.

Abstract: A syringe system, including a plunger, a microcontroller, a battery, and a coil. The syringe barrel having a proximal end, a distal end, and a cylindrical sidewall defining a longitudinal axis, the cylindrical sidewall extending longitudinally between the proximal and distal ends, the sidewall having an exterior surface and defining an internal volume, the plunger being positioned between the proximal and distal ends of the syringe barrel and being movable within the internal volume with respect to the syringe barrel in the longitudinal direction. The syringe barrel further includes a label disposed on the sidewall and having at least two conductive strips extending in a non-parallel direction with respect to the longitudinal axis and having unique lengths. The microcontroller is configured to determine a position of the plunger with respect to the syringe barrel by measuring a current induced in the coil by the at least two conductive strips.
