Abstract:
An evaluation of techniques for human waste receiving, collection and storage during an aerospace mission, with the crewman wearing, or not wearing, a pressure protective garment is presented. Laboratory models, utilizing the most promising techniques, were designed, fabricated and evaluated. A centrifugal urinal, powered by a hand-wound spring motor, was developed for urine collection. Although the principle proved to be satisfactory, further work is required to improve pumping capacity, eliminate air entrainment with the urine, and devise air-urine separation techniques. A disinfectant dispenser operable in zero gravity and a sphereical bladder equipped urine storage tank with means for addition of disenfectant were developed. A flexible plastic in-suit urinal was fabricated, with means for discharging collected urine into the centrifugal urinal. A flexible plastic collector for fecal matter, held in place by a body harness and containing a disinfectant for stabilization purposes, was developed, as was a storage box for containment of used collectors. Further research is required in the areas of penis seals, better control of liquid fecal matter, and odor control.
