摘要:
A system (62, 200, 300, 400, 500, 600, 800, 900, 1000) to administer a medical fluid to an individual, consisting of: a flexible tube (14, 140, 216, 236, 318, 422, 518, 544, 706); a pumping device (64, 202, 302, 404, 504, 604, 804, 904, 1004); At least two cassettes (10, 100, 206, 306, 402, 502, 602, 700, 802, 902, 1002, 1102, 1218, 1302, 1402), each consisting of a casing (12, 212, 312, 702), said cassettes (10, 100, 206, 306, 402, 502, 602, 700, 802, 902, 1002, 1102, 1218, 1302, 1402) are designed to be inserted into the pumping device (64, 202, 302, 404, 504, 604, 804, 904, 1004), respectively; a source of medical fluid, said source of medical fluid is fluidly coupled with the cassette (10, 100, 206, 306, 402, 502, 602, 700, 802, 902, 1002, 1102, 1218, 1302, 1402); and an occlusion sensor device (506, 508, 608) having infrared sensors, said first cassette (10, 100, 206, 306, 402, 502, 602, 700, 802, 902, 1002, 1102, 1218, 1302, 1402) contains the tube (14, 140, 216, 236, 318, 422, 518, 544, 706) containing a material chosen from the group consisting of opaque materials, reflecting infrared light and combinations thereof and a bias protuberance (542) positioned adjacent to a portion (520, 522) of the tube (14, 140, 216, 236, 318, 422, 518, 544, 706) to prevent a side wall (538) of the tube (14, 140, 216, 236, 318, 422, 518, 544, 706) located on the same side as the bias protuberance (542) expands after the bias protuberance (542), so that a side wall (540) of the tube (518, 544) opposite the bias protrusion (542) can continue to expand towards the infrared sensor (506, 508, 608) that would be possible without the bias protuberance (542) to increase the sensitivity d of the detection of occlusions when the first cassette (10, 100, 206, 306, 402, 502, 602, 700, 802, 902, 1002, 1102, 1218, 1302, 1402) is inserted into the pumping device ( 64, 202, 302, 404, 504, 604, 804, 904, 1004); and characterized in that the second cassette (10, 100, 206, 306, 402, 502, 602, 700
