INCREMENTAL RECORDATION ON TEST TUBE

摘要

A method and apparatus for providing patient record information on a specimen tube containing a specimen taken from the patient and for reading the information therefrom when the analysis of the specimen has taken place. A typewriter is used in conjunction with encoding and writing circuits to cause a magnetic recording head to provide binary information on an annular magnetic band on the specimen tube. When the analysis of the tube contents have taken place, the tube is placed in a rotating reading device and a magnetic reading head picks up the coded information and through decoding circuitry either prints out the information and/or stores it in a computer along with the results of the specimen analysis.
