A cassette identification system for use with a medication infusion system having disposable cassettes which are mounted onto a main pump unit is disclosed which uses an optical sensor module to read the identifying bits from the cassette. The identification indicia contained on the cassette each either pass light through a portion of the cassette, or diffuse the light to prevent it from passing through the cassette. The optical module is mounted on the main pump unit, and includes light sources and sensors for each of the identification indicia on the cassette; the system may use either redundant or non-redundant coding for identifying the cassettes.

A system for providing information identifying which of a series of disposable cassettes is installed on a main unit in a medication infusion system, comprising: a projection located on said disposable cassette; an optical receiving module mounted on said main unit, said optical receiving unit defining an opening therein for receiving said projection on said disposable cassette when said disposable cassette is installed onto said main unit; first optical signal source means for providing a first light beam, said first optical signal source means being located in said optical receiving module on one side of said opening; second optical signal source means for providing a second light beam, said second optical signal source means also being located in said optical receiving module on said one side of said opening; first optical signal sensor means for receiving said first light beam, said first optical signal means being located in said optical receiving module on the other side of said opening opposite said first optical signal source means; second optical signal sensor means for receiving said second light beam, said second optical signal sensor means also being located in said optical receiving module on the other side of said opening opposite said second optical signal source means; first identification means for controlling the passage of said first light beam through said projection on said disposable cassette from said first optical signal source means to said first optical signal sensor means, said first identification means alternatively being either conductive of light to allow the passage of light therethrough, or nonconductive of light to prevent the passage of light therethrough, said first identification means being located on said projection on said disposable cassette; and second identification means for controlling the passage of said second light beam through said projection on said disposable cassette from said second optical signal source means to said second optical signal sensor means, said second identification means alternatively being either conductive of light to allow the passage of light therethrough, or nonconductive of light to prevent the passage of light therethrough, said second identification means being located on said projection on said disposable cassette.
