Abstract:
A renal therapy apparatus includes a blood filter, a blood pump, a treatment fluid pump, and a control unit configured to control at least one of the blood pump or the treatment fluid pump during a filter cleaning sequence. In a first phase of the filter cleaning sequence, a first fluid including a blood-compatible and physiologically safe fluid is transferred back and forth across the insides and/or outsides of the blood filter. After the first phase, a second fluid is formed by mixing the first fluid with air. In a second phase of the filter cleaning sequence, the second fluid is transferred across the insides and/or outsides of the blood filter at least one time.

Claim (Index 14):
A method for cleaning a blood filter during a cleaning sequence comprising:\n (i) during a first phase of the cleaning sequence, pumping a first fluid including a blood-compatible and physiologically safe fluid back and forth through the insides and/or the outsides of a plurality of hollow fiber membranes of the blood filter so as to remove or loosen blood residuals, such as blood clots, proteins and/or biological fluid; (ii) after the first phase, forming a second fluid by injecting air into the physiologically safe fluid; (iii) during a second phase of the cleaning sequence, pumping the second fluid through the insides and/or outsides of the plurality of the hollow fiber membranes of the blood filter to further remove or loosen blood residuals therefrom; and (iv) after the second phase, transferring the second fluid along with the removed or loosened blood residuals to a drain, wherein the use of the first and second fluids including the physiologically safe fluid enables the cleaning sequence to be performed, if desired, during a blood treatment.
