In-flight Urine Collection Absorber Evaluation (IUCAs) (DSO 328)

Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Urine collection devices used in Space Shuttle missions have taken up too much space, have tended to leak, and have been cumbersome for men and impossible for women to use. The in-flight urine collection absorber (IUCA) was developed for the collection of small volumes of urine for metabolic studies involving stable (nonradioactive) isotopes such as deuterium (2H) and "heavy oxygen" (18O), which are used to study energy expenditure, water metabolism and body composition. The objectives of this hardware study were to evaluate potential effects of the absorbent filter on the analysis of these isotopes and to evaluate the ease of use of the IUCA by men and women in flight.
