ABSTRACT:
A midstream urine sample collector in which three separate detachable containers are supported from and interconnected by a frame including a fluid passage which interconnects the three containers. The first container is a disposable bag of flexible material which connects to the fluid passage at a point lower than the connection of the passage to the other two containers. An inlet receiving a funnel directs the urine stream into the passage, the urine flowing into the first container because it is at the lowest level. Once the first container is filled, fluid flows through the passage into the second and third containers in that order. The second container is a removable centrifuge vial which can then be used to run the sample tests. Means is provided for cutting off flow of fluid in and out of the first container once it is filled to prevent contamination of the fluid in the second container, which receives the midstream sample.
