Systems and methods for verifying that a biological product is ready for treatment
Systems and method for verifying the timely placement of a container of biolocal cells or fluid within a treatment chamber of a biological fluid treating device are disclosed. The systems and methods utilize a sensor that detects the presence of a container at an appropriate and pre-determined time and, optionally, detects the weight of the container and cells.
1. A system for treating a biological fluid with light comprising:
a) an irradiation device comprising one or more light sources and an irradiation chamber for receiving a container of biological fluid;
b) a detector for detecting that a container is present in said irradiation chamber wherein said detector is configured to detect the weight of said container; and
c) a controller configured to receive information from said detector and verifying that said biological fluid is ready for treatment, wherein said controller is configured to adjust a light dose to be delivered to said container of biological fluid based on the detected weight of said container.
2. The system of claim 1 wherein said controller is further configured to effect the commencement of treatment after said verification.
3. The system of claim 1 wherein said controller is configured to determine if the weight of said container is within a pre-determined weight range.
4. The system of claim 1 wherein said controller is further configured to verify that the detected weight of said container has occurred at a pre-determined time.
5. The system of claim 4 wherein said controller is configured to prevent irradiation of said container of biological fluid upon detection of said weight of said container when said detection occurs at other than said pre-determined time.
6. The system of claim 1 wherein said irradiation device includes a tray for receiving said container.
7. The system of claim 6 wherein said detector is configured to detect the weight of said container received within said tray.
8. The system of claim 1 wherein said detector is associated with said tray.
9. The system of claim 4 wherein said controller is configured to prevent premature placement of said container in said irradiation chamber.
10. A method for verifying the presence of a container of biological fluid within a treatment chamber of a biological fluid treating device at a pre-determined, treatment-ready time, said method comprising:
a) placing a container of biological fluid within a treatment chamber of a biological fluid treating device;
b) detecting the presence of said container of biological fluid by detecting a weight of said biological fluid;
c) optionally comparing the detected weight to a pre-determined weight or weight range for a treatment; and
d) determining whether the biological fluid is treatment-ready based on said comparison; and
e) adjusting a light dose in response to the detected weight of said container of biological fluid.
11. The method of claim 10 further comprising treating said biological fluid when said detected weight substantially equals said predetermined weight or is within said pre-determined weight range.
12. The method of claim 10 comprising adjusting a treatment parameter when said detected weight does not substantially equal said pre-determined weight or is outside said predetermined weight range.
13. The method of claim 10 comprising determining whether said biological fluid is treatment-ready by comparing the time of the detecting step relative to other events in a treatment.
14. The method of claim 10 comprising detecting the weight of said container at a pre-selected time of a treatment.
15. The method of claim 10 wherein said treatment comprises a treatment of a biological fluid with light.
16. The method of claim 15 comprising adjusting the duration of said light treatment in response to the detected weight of said container of biological fluid.
17. The method of claim 15 comprising adjusting the intensity of said light in response to the detected weight of said container of biological fluid.
18. The method of claim 15 comprising detecting said weight of said container of biological fluid to determine whether said biological fluid is treatment-ready.
19. The method of claim 18 wherein said detecting said weight of said container is an indication that said container has been prematurely placed in said treatment chamber.
20. The method of claim 10 further comprising generating an alert when said weight of said container does not substantially equal said pre-determined weight or is outside said predetermined weight range.
21. The method of claim 10 further comprising generating an alert when said container is not treatment ready or when said container has been prematurely placed in said treatment chamber.
