Patent ID: 7571741

Claim:
A urine cartridge comprising: an inlet compartment for receipt of urine; an outlet compartment for transfer of the urine from said inlet compartment to an external drain; a separator separating said compartments into substantially equal volumes for enabling the pressures in said compartments to be substantially equal; top and bottom walls in which said top wall has an opening therein and is disposed to receive and to permit the urine to pass into said inlet compartment, wherein said separator comprises a bowed wall which has a fluid-tight fitting to said top wall sufficient to prevent direct fluid communication between said opening and said outlet compartment and which is spaced from said bottom wall to permit fluid communication between said inlet and outlet compartments, wherein said bowed wall has top and bottom termini which respectively are secured to said cartridge top wall to form said fluid-tight fitting and are spaced from said cartridge bottom wall to provide fluid communication between said inlet and outlet compartments, and further including a baffle which is secured to said bottom terminus of said bowed wall and which is configured to direct the urine from said inlet compartment to said outlet compartment and in such a manner as to minimize the impediment to flow from any deposits on said bottom wall.
