1. A method of delivering fluid to multiple patients, comprising:
- (a) providing a fluid delivery system comprising a reusable fluid path and a plurality of per-patient disposable fluid paths, the reusable fluid path including(i) a first fluid source;
(ii) a second fluid source;
(iii) a helical vane mixer adapted to mix fluids from the first and second fluid sources, the plurality of per-patient disposable fluid paths each including a first end connectable to a patient of the multiple patients and a second end connectable to the reusable fluid path;
(b) connecting the second end of a first per-patient disposable fluid path of the plurality of per-patient disposable fluid paths to the reusable fluid path and the first end of the first per-patient disposable fluid path to a first patient of the multiple patients to define a fluid path between the first and second fluid sources and the first patient;
(c) mixing the fluids from the first and second fluid sources to create a first mixture with a predetermined content for the first patient;
(d) delivering the first mixture to the first patient through the first per-patient disposable fluid path;
(e) disconnecting the first per-patient disposable fluid path from the reusable fluid path and the first patient;
(f) connecting a second per-patient disposable fluid path to the reusable fluid path and a second patient of the multiple patients;
(g) mixing the fluids from the first and second fluid sources to create a second mixture with a predetermined content for the second patient; and
(h) delivering the second mixture to the second patient through the second per-patient disposable fluid path.

-
(a) providing a fluid delivery system comprising a reusable fluid path and a plurality of per-patient disposable fluid paths, the reusable fluid path including (i) a first fluid source; (ii) a second fluid source; and (iii) a static mixer configured to mix the fluids from the first and second fluid sources to create a mixed fluid, the plurality of per-patient disposable fluid paths each including a first end connectable to a patient of the multiple patients and a second end connectable to the reusable fluid path; (b) connecting the second end of a first per-patient disposable fluid path of the plurality of per-patient disposable fluid paths to the reusable fluid path and the first end of the first per-patient disposable fluid path to a first patient of the multiple patients to define a fluid path between the first and second fluid sources and the first patient; (c) mixing the fluids from the first and second fluid sources to create a first mixture with a predetermined content for the first patient; (d) delivering the first mixture to the first patient through the first per-patient disposable fluid path; (e) disconnecting the first per-patient disposable fluid path from the reusable fluid path and the first patient; (f) connecting a second per-patient disposable fluid path to the reusable fluid path and a second patient of the multiple patients; (g) mixing the fluids from the first and second fluid sources to create a second mixture with a predetermined content for the second patient; and (h) delivering the second mixture to the second patient through the second per-patient disposable fluid path. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
