  • Device for collection and preservation of tissue or stool samples
    Patent number: 8961429
    Abstract: An arrangement for collecting a tissue or stool sample has a sample vial and a source of preservative fluid. A fluid valve controls a flow of the preservative fluid from the source of preservative fluid to the sample vial. An air equalization vent tube is coupled to the source of preservative fluid and an air valve controls a flow of air through the air equalization vent tube, the air valve and the fluid valve being actuated simultaneously. A scoop for collecting the sample is coupled to the sample vial coupler and extends into the sample vial. The preservative fluid flows from the source of preservative fluid to the sample vial by force of gravity upon actuation of the fluid valve. The air equalization vent tube transfers air from the sample vial to the source of preservative fluid upon actuation of the air valve.
