Abstract

This invention relates generally to the field of medical devices for delivering medicinal fluids to patients during medical procedures and more particularly, this invention relates to improved medical fluid delivery systems and methods of use which incorporate a closed loop information path from the manufacturer to a product user such as a hospital or other medical institution and back to the original manufacturer. The information originally incorporated with the product is used by the consumer to aid in use of the product. The information which accompanies the product is updated and new information is added in order to provide the manufacturer with information on how the product is used.

Claims

1. A method for using a consumable medical product including storing information on and retrieving information from a record member in association with the consumable medical product comprising the steps of:

a) storing information relative to the consumable medical product on the record member at a vendor site;

b) retrieving the stored information at a consumer site;

c) calculating parameters for operation of a system which incorporates the consumable medical product based on the retrieved information;

d) storing new information relating to using the consumable medical product on the record member at the consumer site; and

e) retrieving the new information at the vendor site.

2. The method for using a consumable medical product of claim 1, further comprising the step of providing a readable/writable electronic device as the record member.

3. The method for using a consumable medical product according to claim 2, wherein a magnetic strip is provided as the record member.

4. The method for using a consumable medical product according to claim 1, further comprising adding new information at the vendor site for reuse of the product.

5. The method for using a consumable medical product according to claim 1, wherein the retrieved information is used in billing the consumer site.

6. A method of using a consumable medical product including transferring information concerning the consumable medical product comprising the steps of:

a) receiving the consumable medical product having an associated record member at a vendor site;

b) writing information to the record member at the vendor site; and

c) retrieving the stored information at a consumer site for determining at least one operating parameter for a system for using the consumable medical product;

wherein said at least one operating parameter is at least one member selected from the group consisting of setting at least one pressure limit for the system, determining a volume of the system, removing air from the system, calibrating a pumping mechanism and preventing use of fluids beyond an expiration date.

7. The method of claim 6, wherein the product is a medical fluid delivery element.

8. A method for using a consumable medical product including transferring product information concerning said consumable medical product comprising the steps of:

a) storing information on a record member associated with the consumable medical product at a vendor site;

b) retrieving the stored information at a consumer site;

c) calculating operating parameters for using the consumable medical product system based on the retrieved information;

d) returning new information to the vendor site from the system via electromagnetic transmission.
