Abstract
Abstract This invention relates to a microprocessor-based medical pump (10) with a number of manual controls. The operation of this pump requires the attachment of a magnetic label (30) to the front of the pump. This magnetic label includes a given number of strong permanent magnets in a pre-determined configuration which indicate the pharmaceutical product type and concentration to be infused. The magnetic label also changes the visual scales around the manual controls. Hall Effect sensors read the pre-determined configuration and send the data to the microprocessor which also reads the manual controls. Using the pre-determined configuration data and the manual control data, the microprocessor determines the desired infusion parameters.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
63 words
An apparatus comprising: pumping means; means for controlling operation of said pumping means; indicator means which includes information in a pre-arranged configuration for a selected mode of pump operation, wherein said control means senses said pre-arranged configuration when said indicator means is placed adjacent to said control means and wherein said control means controls said pumping means in accordance with said pre-arranged configuration.
Claim 2
Independent Claim
63 words
An apparatus comprising: pumping means; means for controlling operation of said pumping means; indicator means which includes information in a pre-arranged configuration for a selected mode of pump operation, wherein said control means senses said pre-arranged configuration when said indicator means is placed adjacent to said control means and wherein said control means controls said pumping means in accordance with said pre-arranged configuration.
Claim 3
Dependent Claim
14 words
