Abstract

The disclosed inventions provide for improvements to data storage that is integral to sample containers such as test tubes. Systems and methods for enclosing radio frequency read/writeable chips within sample containers are described, as well as systems and methods for gathering data to be stored. Examples of useful medical contexts for the technology are presented, including for physician and lab blood testing data. Some embodiments disclose systems and methods that can track data and process samples with the help of a portable unit. Some embodiments of the portable units not only assist in entering, storing, and transmitting medical data, they also comprise novel systems that can process and or analyze whole blood. Accordingly, centrifuge portions are described, including two novel types of test tube valves that function in concert with the described centrifuge portions.

providing a plastic material;

forming the plastic material in the general shape of a standard test tube with an open end that opens into a sample-containing portion, a closed end, and a chamber portion at the closed end, the chamber portion not open to the sample-containing portion;

inserting an RFID chip into the chamber portion; and

covering the chamber portion with a plastic cover that provides a rounded bottom end on the test tube.

8. The method of claim 7, further comprising laminating the RFID chip with a protective layer.

9. The method of claim 7, further comprising surrounding the RFID chip with a liquid substance.

10. The method of claim 9, further comprising allowing the liquid substance to harden surrounding the RFID chip.

11. The method of claim 7, wherein sealing the chamber portion closed comprises heating the plastic material.

12. A method of gathering information related to a medical specimen, the method comprising:

providing a portable device that comprises a centrifuge and a computer;

entering victim and/or incident information into the portable device;

obtaining a biological sample from the victim and placing the sample in a sample container comprising an electronic data storage device;

processing the sample with the portable device; and

using the portable device to write electronic data to the electronic data storage device.

13. The method of claim 12, wherein using the portable device to write electronic data to the electronic data storage device comprises writing data that relates to the results of processing the sample.

14. The method of claim 12, wherein using the portable device to write electronic data to the electronic data storage device comprises writing data that relates to the identity of the victim.

15. The method of claim 12, further comprising wirelessly transmitting the electronic data to a remote location from the portable device.

16. The method of claim 15, wherein wirelessly transmitting the electronic data to a remote location from the portable device further comprises transmitting the electronic data to a hospital.

17. The method of claim 15, wherein wirelessly transmitting the electronic data to a remote location from the portable device further comprises transmitting the electronic data to a government agency.
