title: A slow-speed gravity delivery system for laboratory specimens.
abstract: A prototype system for the slow-speed transport of specimens by gravity was installed in New York University Hospital in May 1974. Blood, urine, body fluids and other specimens, except for 24-hour urines, are transported inside cylindrical containers that descend at constant velocities between 60 and 120 cm/sec, depending on the weight of the contents. Containers could be dispatched at six-second intervals, and each could carry as many as 15 blood specimens. Experience with the system has demonstrated that slow-speed gravity transport is practical and safe. No specimen has been lost, damaged or broken. Performance was acceptable, but some design modifications were needed. In February 1975, the system was expanded to provide service to the Intensive Care and Coronary Care Units.
