A closed specimen collection system for urine includes a port tube with a one-way valve adapted to fit a shaped nozzle that is attached to tubing ofto an indwelling urinary catheter A collection tube has a shaped nozzle at the proximal end adapted to fit sealably into the port tube adjacent the one-way valve. A specimen collection system for blood samples includes a collection tube that has a shaped nozzle adapted to fit sealably into a port connected to a centrally inserted venal catheter. Both versions use a specimen container with a hollow body, a front end with a sealable aperture that attaches to the end of the collection tube A piston fits closely within the hollow body and is attached to an actuating rod. When the actuating rod is retracted, urine or blood will flow into the specimen container through the collection tube in a sterile condition. |
