Pump system including cassette sensor and occlusion sensor
First Claim
1. A sensing device for a pump control module designed for use with a cassette having a pump surface with a projection, the sensing device being positioned on an interface surface of the pump control module for sensing an occlusion condition in a delivery conduit and for sensing the projection on the cassette, the sensing device comprising:
- a first layer having a bottom surface with a first occlusion conductive pattern and a first identification conductive pattern; and
a second layer having a top surface with a second occlusion conductive pattern aligned with the first occlusion conductive pattern of the first layer and a second identification conductive pattern aligned with the first identification conductive pattern of the first layer.
