ABSTRACT:
A method, and apparatus, for rotating immobilized subhuman primate animal test subjects about one or more axes according to a preselected sequence to simulate weightlessness and to minimize trauma during simulated zero or micro-gravity studies is disclosed. The method includes intermittent rotation of the test subject ninety degrees every thirty minutes about an axis parallel to both the spine of the test animal and to the ground, and intermittent rotation of the test subject forty-five degrees every three to five minutes about each of two axes. The method is performed using a timed roto-positioning apparatus having a frame, a subframe rotatably attached to the frame, and a carrier for a primate restraint system rotatably attached to the subframe. Two motors, controlled by a programmable controller, individually rotate the subframe and the carrier according to a preselected sequence. The preferred embodiment for the apparatus is a modified A-frame structure made from welded channel aluminum beams and equipped with casters and lifters to move and securely position the apparatus. A tube with rotatable fittings is used to supply drinking water to test animals and electrical slip rings are used for transmitting physiological sensor signals from the test animal through the rotating connections of the carrier, subframe and frame. Radio telemetry may be used in place of the electrical slip rings.
