ABSTRACT:
A device which not only removes the stopper from a test tube or vacutainer without any human contact, but one which also stores and retains the removed stoppers is disclosed. The device has a container for receiving and retaining the removed stoppers which communicates with a stopper extractor. The stopper extractor has one extractor lip which bears against a first side of the vacutainer and a second extractor lip which engages an opposite side of the stopper such that relative pivoting movement between them exerts a force on the stopper to urge it out of the vacutainer. A spring device is attached to the stopper extractor and has a leaf spring which contacts one side of the vacutainer after it has been inserted into the stopper extractor. During pivoting movement between the stopper extractor and the test tube or vacutainer, the leaf spring is further displaced from its normal, at-rest position. Once the stopper has been removed from the test tube, the leaf spring snaps back into its normal position, thereby exerting a force on the removed stopper urging it into the container.
