| titleOfInvention | Fluid control apparatus and methods |
| abstract | A fluid regulator (50), which can be used for kidney dialysis, includes a blood supply tube (51) for supplying blood from the patient to one side of a dialyzer (53). Blood is reinjected into the patient through the tube (56). An occlusive peristaltic pump (60) is arranged to drive fluid from a source of dialysate (80) to another side of the dialyser (53) through the tube (61). The two sides of the dialyzer are separated by a filtration membrane. An occlusive peristaltic pump (65) is installed to drive fluid from the dialyzer (53), along the tube (62) to a waste container (66). A fluid tube (70) communicates with the tube (62), a pump (71) being installed to drive fluid along the tube to a container (73) for collecting the filtered product. Occlusive pumps (60, 65) are mechanically connected to pump fluid with the same flow. In use, blood is pumped through the tubes (51, 56), and fluid is caused to flow through the pumps (60, 65) to and from the dialyzer. In this arrangement, no net fluid flow passes from the blood receiving side of the dialyzer (53) to the other side. A clear flow of fluid through the filtration membrane can be obtained when the fluid is pumped to the container (73) via the pump (71). In this case, the fluid flows through the dialyzer (53) from the patient depending on the volume of fluid removed by the pump (71). Thus, the volumetric regulation of the fluid withdrawn from the patient can be carried out. In a variant, the volumetric regulation of the fluid withdrawn can be carried out by adjusting the difference in speed of rotation of the pumps (60 and 65) and collecting the ultrafiltered product. The apparatus can be used generally in filtration processes or dialysis treatment. The device can be modified to perform hemofiltration. |
