Evaluation of the disposable absorption containment trunk for female U-2 and TR-1 pilots.
Female U-2 and TR-1 pilots needed a urine collection device as part of their high flight pressure suit ensembles. The Disposable Absorption Containment Trunk (DACT) had been designed for short term use with the NASA Space Shuttle Program. This study evaluated the DACT for the extended and repetitive use required for integration into the U-2 and TR-1 aircraft. Six female subjects were tested wearing a custom-fit DACT and the 1030 full pressure suit ensemble with torso harness. They were strapped into the U-2 ejection seat with parachute and seat kit for 10 h and 45 min every 3 d for a total of 5 sessions. The DACT was evaluated for absorptive capability and comfort. Subjects were monitored for dermatitis, vaginitis, and urinary tract infections. The DACT reliably absorbed menstrual flow and urinary outputs to 950 cc. Higher urinary outputs resulted in minimal leakage. Dermatitis in the form of mild erythema and chafing was present, but cleared between sessions without medical intervention. Complaints concerning comfort were minor and limited to fit problems. One case of vaginitis developed. There were no cases of urinary tract infection. The DACT was found to be an acceptable method of urine collection for female U-2 and TR-1 pilots. Minor changes in design will enhance the comfort and performance of the DACT.
