ABSTRACT:
A hand-held device for causing a blood sample to be controllably drawn into a flexible envelope or the like. The envelope is placed between a rigid and a hinged member disposed within the housing of the device, and a roller advanced along the hinged member to progressively compress the envelope. When the wheel is moved back along its path, the envelope is allowed to progressively expand thereby drawing the blood sample into the envelope.
