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.
1974年5月，纽约大学医院安装了一套通过重力实现标本低速传输的原型系统。血液、尿液、体液及其他标本（24小时尿液标本除外）被放置在圆柱形容器内传输，容器根据所装物品重量以60至120厘米/秒的恒定速度下降。容器每隔6秒发送一次，每个容器最多可携带15份血液标本。该系统的使用经验表明，低速重力传输既实用又安全。没有标本丢失、损坏或破碎。性能尚可，但需要进行一些设计改进。1975年2月，该系统进行了扩展，以便为重症监护病房和冠心病监护病房提供服务。
