Title: Apparatus, systems and methods for tracking drug administration
Inventor: MACLEOD RONALD R
IPC: A61M5/31
Filed: 2008-05-07
Abstract: According to aspects of the invention provided are apparatus, systems and methods for monitoring the presence/absence of syringes within a storage unit and monitoring the amount of drugs that are discharged from syringes when they are not within the storage unit. Monitoring the presence/absence of syringes within the storage unit is accomplished using a combination of imaging sensors and a RFID tag reader. The method includes detecting and decoding signals from RFID tags to determine which syringes are present/absent from the storage unit and the times at which syringes are removed and returned to the storage unit. The method also includes collecting visual information with respect to when syringes are removed and returned to the storage unit. The timing information from the RFID reader and the imaging sensors are compared to resolve the identification of syringes. Once the timing information from the RFID reader and the imaging sensors is resolved so as to identify specific syringes, the visual information can be used to calculate the amount of a drug discharged from each syringe.
