Beckman physiological and cardiovascular monitoring system - 13739ce12d4ef81f8fb5d53f64cc6702

This cardiovascular reflex conditioning system was designed by Beckman Instruments' Space Engineering Group (SEG) in 1964 for NASA's Projects Gemini and Apollo. This system was part of astronauts' flight suits and would inflate and deflate cuffs to stimulate blood flow to lower limbs, preventing the usual diuretic effects of prolonged weightlessness during space flight.
