In plasmapheresis, this disclosure teaches a method for eliminating mistakes in returning a container of red blood cells to the correct donor. A mating plug and receptacle of distinctive shape are connected between the container and its support. If the plug and receptacle do not match, there is no convenient way to support the container for intravenous delivery of the red blood cells to the donor. The basic concept can be applied also to a wide variety of other services. |
