To initiate treatment two relatively standard 18G needles 102 and 103 are introduced into suitable peripheral veins (on the same or different arms) for the withdrawal and return of the blood. This procedure is no different from blood draw or IV therapy. Needles and attached to tubing 104 and 105 and secured to skin with attachments 106 and 107. The blood circuit that consists of the blood filter 108, tubes, pressure sensors 109, 110 and 111 and the ultrafiltrate collection bag 112. The circuit is supplied in one sterile package and is never reused. It is easy to mount on the pump 113 and can be primed and prepared ready for operation within minutes by one person.
[0022]During operation, the present invention requires minimal intervention from user. User sets the maximum rate a...
