Abstract
Abstract 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
99 words
A method for avoiding mistakes in matching a patient to a substance to be administered and comprising the steps of arranging a connection position relative to the patient in which position a container having the substance therein must be placed for administering the substance to the patient, providing a plug having a distinctive configuration, attaching said plug to said container, providing a receptacle with a configuration which conforms to that of the plug, placing said receptacle in said connection position, and inserting the plug into the receptacle for connection thereto and for supporting the container in said connection position.
Claim 2
Independent Claim
99 words
A method for avoiding mistakes in matching a patient to a substance to be administered and comprising the steps of arranging a connection position relative to the patient in which position a container having the substance therein must be placed for administering the substance to the patient, providing a plug having a distinctive configuration, attaching said plug to said container, providing a receptacle with a configuration which conforms to that of the plug, placing said receptacle in said connection position, and inserting the plug into the receptacle for connection thereto and for supporting the container in said connection position.
Claim 3
Dependent Claim
122 words
In plasmapheResis, a method for avoiding mistakes in returning red blood cells to the correct donor and comprising the steps of arranging an elevated position relative to the donor in which position a container having the donor''s red blood cells therein must be placed for intravenous delivery of the red blood cells back to the donor, providing a plug which has a distinctive configuration, attaching said plug to said container, providing a receptacle which has a configuration that conforms to that of the plug, placing said receptacle in said elevated position, and inserting the plug into the receptacle for connection thereto and for holding the container in its elevated position for the intravenous delivery of the red blood cells to the donor.
Claim 4
Dependent Claim
122 words
In plasmapheResis, a method for avoiding mistakes in returning red blood cells to the correct donor and comprising the steps of arranging an elevated position relative to the donor in which position a container having the donor''s red blood cells therein must be placed for intravenous delivery of the red blood cells back to the donor, providing a plug which has a distinctive configuration, attaching said plug to said container, providing a receptacle which has a configuration that conforms to that of the plug, placing said receptacle in said elevated position, and inserting the plug into the receptacle for connection thereto and for holding the container in its elevated position for the intravenous delivery of the red blood cells to the donor.
Claim 5
Independent Claim
129 words
A method for performing plasmapheresis and comprising the steps of arranging an elevated support relative to the donor in which support a container having red blood cells therein must be placed for intravenous return of the red blood cells to the donor, providing a plug which has a distinctive cross-sectional shape, attaching the plug to a suitable blood container, withdrawing blood from the donor into the blood container, extracting plasma from the blood by centrifuging the blood container with the plug attached thereto, providing on the support a receptacle which has a shape which conforms to the cross-sectional shape of the plug, and thereafter inserting the plug into the receptacle to position the blood container on the support for intravenous delivery of the red blood cells to the donor.
Claim 6
Independent Claim
129 words
A method for performing plasmapheresis and comprising the steps of arranging an elevated support relative to the donor in which support a container having red blood cells therein must be placed for intravenous return of the red blood cells to the donor, providing a plug which has a distinctive cross-sectional shape, attaching the plug to a suitable blood container, withdrawing blood from the donor into the blood container, extracting plasma from the blood by centrifuging the blood container with the plug attached thereto, providing on the support a receptacle which has a shape which conforms to the cross-sectional shape of the plug, and thereafter inserting the plug into the receptacle to position the blood container on the support for intravenous delivery of the red blood cells to the donor.
Claim 7
Dependent Claim
19 words
The method of claim 3 and delivering saline solution intravenously to the donor along with the red blood cells.
Claim 8
Dependent Claim
15 words
The method of claim 4 and providing means for retaining the plug in the receptacle.
Claim 9
Dependent Claim
32 words
The method of claim 3 and maintaining the donor on a cot throughout performance of the method, arranging the support adjacent the cot, providing means for pairing the support with the cot.
Claim 10
Independent Claim
117 words
A method for performing plasmapheresis and comprising the steps of: providing a stand for suspending thereon a container for red blood cells to be returned to the donor of said cells; providing an engaging member having a distinctive configuration and a matching receiving member; assigning said members to the donor; attaching said engaging member to a container and said receiving member to said stand; thereafter filling said container with the whole blood donated by the donor and extracting the plasma from the blood by centrifuging; and thereafter inserting said member into said receiving member to suspend said container with the red blood cells therein from the stand for return of the red blood cells to the donor.
