Abstract

A pump housing which contains a plurality of linear peristaltic pumps and receives a fluid source cartridge. The cartridge is provided with retaining knobs for engaging retaining holes in the front end of the pump housing. A cartridge further contains a tab at its rear end for engaging a locking mechanism in the pump housing. The cartridge contains linear fluid conduits which align with the linear peristaltic pumps for pumping fluid from the fluid source pouches within the cartridge. Each pump is individually controlled by a programmable controller within the pump.

Claims

1. A multiple fluid source cartridge comprising;

a rigid housing;

a plurality of fluid containing compartments located within said housing;

a linear conduit connected to each one of said fluid containing compartments;
