Abstract: A disposable eye piece system, including the eye piece and other disposable components, for a precision ultrasonic scanning apparatus is disclosed. The eye piece includes a fill port, a vent port and a drain port molded into the base of the eye piece. An RF Identification chip may be molded into the plastic base of the eye piece or, alternately into the conformable face seal of the eye piece. The components of a disposable eye piece system form an integrated disposable package that can be assembled, packaged, transported and used while maintaining the eye piece and saline solution in a sterile condition. The protective shipping container 1) protects the eye piece from damage, human contact and exposure to ambient air during shipping and storage and 2) allows the scanning physician or technician to attach the eye piece to the scanning machine without compromising the sterile condition of the eye piece.

Abstract: A fluid flow chamber cassette that can be mounted with either its front wall or rear wall against a supporting machine and has a flexible tube that extends from a sidewall and forms a loop that is symetrical about a loop axis that is transverse to the side wall so that the loop will be acted upon by a pump roller on the machine both when the front wall is against the machine and when the rear wall is against the machine. Also disclosed is automatically fixing the initial liquid levels and amounts of air in venous and arterial chambers of fluid flow transfer device apparatus by having the arterial chamber inlet enter the arterial chamber at a position higher than the arterial chamber outlet, having the venous chamber inlet enter the venous chamber at a position higher than the venous chamber outlet, and priming the apparatus by causing reverse flow, so that the liquid rises in the venous and arterial chambers to the level of the entrances of the inlets.
