Abstract
A man-portable dialysate generator with a forward osmosis membrane module, a concentrated aqueous salt solution reservoir, a non-sterile water feedstock inlet, and a collection reservoir that produces sterile dialysate from non-sterile feed water. The dialysate generator does not have an electric-powered pump to move fluids across the osmosis membrane, or does not have electric-powered pumps that generate more than 5 psi for fluid pressure. The dialysate generator is man-portable, less than 50 pounds and maybe less than 31 pounds, and preferably less than 10 pounds. The device is particularly advantageous for use in forward deployed military patient care, disaster response or remote medical care situations away from clean water and electricity.
