Abstract

A medical device includes a mechanism configured to perform a first medical operation, a scanner and a processing circuit. The scanner is configured to scan data displayed on a computer screen by a second medical device separate from the medical device. The processing circuit is configured to receive the scanned data from the scanner. The scanned data comprises an indication that a second medical operation was performed by the second medical device. The processing circuit is configured to proceed with the first medical operation based on the indication that the second medical operation was performed by the second medical device.

Claims

1. A method of performing a medical operation on a specimen, comprising:

performing a first medical operation on the specimen using a first medical device;

scanning a two-dimensional machine readable construct from a computer screen of a second medical device;

receiving an indication from the machine readable construct that a second medical operation has been performed on the specimen by the second medical device;

based on receiving the indication that the second medical operation has been performed, performing at least one of a third medical operation using the first medical device and a report function using the first medical device.

2. The method of claim 1, wherein the scanning is performed using a digital camera, further comprising operating a character recognition algorithm to generate the indication that the second medical operation has been performed on the specimen.

3. The method of claim 2, wherein the character recognition algorithm further generates a specimen identifier.

4. The method of claim 3, wherein the specimen identifier comprises a patient identifier.

5. The method of claim 3, wherein the character recognition algorithm further generates at least two parameters representative of the second medical operation performed by the second medical device.

6. A method of operating an apheresis device, comprising:

separating a component from a patient'"'"'s blood at the apheresis device;

scanning a machine readable indicator from a computer screen of a blood treatment device separate from the apheresis device, the indicator indicating that the separated component has been processed by the blood treatment device;

receiving input data from the scanner; and

enabling reinfusion of the separated component to the patient based on the input data.

7. The method of claim 6, wherein the machine readable indicator is a linear barcode or a two-dimensional matrix barcode.

8. The method of claim 6, wherein the input data further comprises a patient identifier which identifies the patient.

9. The method of claim 6, further comprising receiving a user input signal from a keyboard, after receiving the input, to confirm the user wishes to proceed with the first medical operation.

10. The method of claim 6, further comprising receiving a patient identifier, determining whether the patient identifier matches a patient identifier stored in memory, determining from the input data whether the separated component has been processed by the blood treatment device, and enabling the reinfusion based on the patient identifiers matching and the input data indicating the separated component has been processed.

11. The method of claim 6, further comprising processing the separated component by irradiating the separated component at the blood treatment device separate from the apheresis device.

12. The method of claim 11, wherein the apheresis device and the blood treatment device are not in electronic communication with each other.

13. The method of claim 6, wherein the separated component is plasma, further comprising processing the plasma by immunoadsorption or lipid column filtration.

14. A method, comprising:

providing a first medical device;

performing a second medical operation using a second medical device which is separate from the first medical device and comprises a computer screen;

displaying data on the computer screen;

scanning the data on the computer screen, the scanned data comprising an indication that the second medical operation was performed by the second medical device;

receiving the scanned data at the first medical device;

determining at the first medical device that the second medical operation was performed; and

based on the determination that the second medical operation was performed, proceeding with a first medical operation using the first medical device.

15. The method of claim 14, wherein the first medical device and the second medical device are not in electronic communication with one another.

16. The method of claim 15, wherein the first medical device and the second medical device are independent devices, each having its own housing spaced apart from each other.

17. The method of claim 16, wherein the scanned data comprises a patient identifier, further comprising comparing the patient identifier to a patient identifier stored in a memory of the first medical device before proceeding with the first medical operation.

18. The method of claim 17, further comprising performing a third medical operation for the patient at the first medical device prior to receiving the scanned data from the scanner, wherein the first medical operation, second medical operation and third medical operation are performed with respect to the same patient.

19. The method of claim 18, further comprising:

after receiving the scanned data, displaying a text prompt on a screen of the first medical device to request whether a user wishes to proceed with the first medical operation;

receiving a user input signal after receiving the scanned data to confirm the user wishes to proceed with the first medical operation, wherein the user input signal is received via a user pressing the user input device.

20. The method of claim 18, wherein performing the second medical operation comprises irradiation of a blood component of a patient, wherein performing the first medical operation comprises returning the blood component to the patient, wherein performing the third medical operation comprises separating the blood component from blood of the patient.
