Method and apparatus for monitoring transfusion of blood
View Patent ↗Method and apparatus are described for ensuring that blood transfused into a patient is the correct blood for that patient, and that a complete audit trail is created that will allow later tracing of blood from donation through to transfusion.
1. Apparatus for tracking the movement of blood products destined for transfusion to a patient at a first location, comprising:
a patient identification tag for each patient, each of said patient identification tags encoding a unique patient identification code;
a first blood product identification tag attached to each unit of said blood products, each of said first blood product identification tags encoding a unique blood product identification code;
a second blood product identification tag attached to each unit of said blood products, each of said second blood product identification tags encoding a unique blood product identification code and a unique patient identification code;
a caregiver identification tag for each caregiver, each of said caregiver identification tags encoding a unique caregiver identification code;
storage means for storing said blood products, said storage means located at a second location that is remote from said first location;
tag reading means associated with said storage means for reading the first and second blood product identification codes and caregiver identification codes; and
a computer coupled to said tag reading means, said computer including software for recording blood product identification codes for each blood product stored in said storage means, recording patient identification codes associated with each blood product stored in said storage means, recording the caregiver identification code for each caregiver who accesses the storage means, and while the caregiver is at the second location, retrieving the patient identification code associated with the unique blood product identification code from the first blood product identification tag and comparing it to the patient identification code from the patient identification tag, or comparing the unique patient identification code from the second blood product identification tap to the unique patient identification code from the patient identification tag.
2. The apparatus of claim 1 wherein the first and second blood product identification tags comprises a radio frequency identification tags.
3. The apparatus of claim 2 wherein the caregiver identification tag comprises a radio frequency identification tag.
4. The apparatus of claim 3 wherein said storage means includes a lock under the control of said computer.
5. The apparatus of claim 4 wherein said computer includes blood product identification code information for each blood product contained in said storage means.
6. The apparatus of claim 5 wherein said computer opens the lock in response to a request from a caregiver only when said request includes a blood product identification code that matches a blood product identification code for a blood product stored in said storage means.
