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.

First claim

What is claimed is:

1. An assembly comprising:
an injection device having a first, unused state and a second, used state and comprising a syringe for administering liquid medicine into a patient's body, and
a labeling apparatus for presenting an application status of the injection device comprising:
a label having an electrochromic element, the label being at least partially disposed on an exterior surface of the injection device and being configured to display a predetermined feature in response to an electric current when the injection device is in the second, used state, the predetermined feature including a machine-readable code selected from the group consisting of a linear bar code and a quick response code;
a power source disposed in or on the injection device; and
a switch 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 injection device from the first state to the second state, the switch comprising a plurality of conductive members for connecting or disconnecting the power source and the label,

wherein the switch is operated by a plunger of the injection device that is movable when the injection device is actuated from the first state to the second state, and
wherein at least one first conductive member selected from the plurality of conductive members is electrically connected to one of the label or the power source, and at least one second conductive member selected from the plurality of conductive members, other than the first conductive member, is connected to the plunger.

2. The assembly of claim 1 , wherein the plunger has a plurality of positions.

3. The assembly of claim 2 , wherein the plurality of positions comprises at least a fully plunged position and a non-fully plunged position.

4. The assembly of claim 1 , wherein the first conductive member contacts the second conductive member when the plunger is moved to the fully plunged position during a normal course of injection for completing the connection between the power source and the label.

5. The assembly of claim 1 , wherein the power source is a zinc-carbon battery, a alkaline battery, a nickel-cadmium battery, a lithium battery or a manganese dioxide battery.

6. A system for administering an injection device, comprising:
an assembly in accordance to claim 1 ; and
a scan device for scanning the label.

7. The system of claim 6 , wherein the scan device comprises an application program for scanning the label.

8. The system of claim 6 , wherein the scan device is configured to acquire use information of the injection device based on a scan result of the label.

9. The system of claim 8 , wherein the use information comprises a device status, a product use, injection verification, a timestamp or a combination thereof.

10. The system of claim 6 , wherein the scan device is configured to present a message on the scan device in response to the scan result of the label.

11. The system of claim 10 , wherein the scan device is configured to communicate with a medical organization.

12. The system of claim 11 , wherein the scan device is configured to transmit use information of the injection device to the medical organization.

13. The system of claim 11 , wherein the scan device is configured to present instructive information received from the medical organization.
