Abstract

The present invention provides a tracking device for communicating information regarding an object, the tracking device comprising a housing including a disk having a central axis and an outer circumference, and a plurality of arms attached to the outer circumference of the disk forming a cavity. The tracking device further comprises a transponder disposed within the cavity and configured to transmit an electromagnetic signal in response to an electromagnetic wave, the transponder including an integrated circuit having a memory and an antenna electrically coupled to the integrated circuit.

Claims

1. A radio frequency safety system for a drug container, the system comprising:

a housing including a cavity; and

a radio frequency identification tag disposed within the cavity, that stores information and the information may be accessed by a radio frequency signal in response to an incoming radio frequency signal, the transmitted radio frequency signal containing tracking information and drug identification information;

wherein the housing is attached to the drug container,

wherein the drug container is a syringe including a plunger having a distal end, and

wherein the housing is snap-fit onto the distal end of the plunger.

2. The radio frequency safety system of claim 1, further comprising a disk having an outer circumference and a plurality of arms attached to the outer circumference of the disk forming the cavity.

3. A housing for a tracking device, the housing comprising:

a disk having a central axis and outer circumference; and

a plurality of arms flexibly attached to the outer circumference of the disk and descending from the disk forming a cavity;

wherein the tracking device is disposed between the disk and a mating surface of a medical container, and

wherein the medical container comprises a syringe.

4. The housing of claim 3, wherein the syringe includes a plunger having a distal end, and wherein the housing is snap-fit onto the distal end of the plunger.

5. The housing of claim 3, wherein the tracking device comprises a transponder disposed within the cavity and configured to store information and transmit an electromagnetic signal in response to an electromagnetic wave, the transponder comprising an integrated circuit having a memory and an antenna electrically coupled to the integrated circuit.
