Title: Body fluid collection device

Abstract: A technique is provided for collecting and transferring body fluids such as blood or sputum. A blood sample is taken through a tube into an evacuated chamber. After the sample has been drawn it may be centrifuged to separate red cells from the plasma. Samples are then withdrawn from the first chamber into a second evacuated chamber where several analysis tubes are located. The sample is thus subdivided for analysis without exposure of the sample to the person making the tests. In another embodiment sputum is collected in a first chamber and is first blended with a preservative and then transferred to a second chamber where analysis tubes are located. Transfer is likewise without exposure of the person or contamination of the sample.
