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 of storing information on and retrieving information from a record member in association with a medical fluid delivery element comprising the steps of:

a) storing information on the record member at a vendor site;

b) retrieving the stored information at a consumer site;

c) calculating parameters for operation of a medical fluid delivery system which incorporates the medical fluid delivery element based on the retrieved information;

d) storing new information on the record member at the consumer site; and

e) retrieving the new information at the vendor site.

2. The method of storing and retrieving information of claim 1, further comprising the step of providing a readable/writable electronic device as the record member.

3. The method according to claim 2, wherein a magnetic strip is provided as the record member.

4. The method according to claim 1, wherein the retrieved information is used in billing the consumer site.

5. The method according to claim 1, wherein new information is added at the vendor site for reuse of the product.

6. A method of storing information on and retrieving information from a medical fluid delivery module comprising the steps of:

a) storing information on the fluid delivery module at a vendor site;

b) retrieving the stored information at a consumer site;

c) calculating parameters for operation of a medical fluid delivery system which incorporates the medical fluid delivery module based on the retrieved information;

d) storing new information on the fluid delivery module at the consumer site; and

e) retrieving the new information at the vendor site.

7. The method according to claim 6, wherein the information is stored with a machine readable bar code.
