Problems solved by technology
In previous animal experiments, the device for fixing animals (rats) on the centrifuge was just a rectangular box, which could not be adjusted in size. Rats could retract, turn their heads, or even turn around in self-protective positions in the box, thus weakening the + Gz, it is difficult to guarantee the success and stability of the model, which becomes the bottleneck of our research on prevention and control measures based on this model

Embodiment Construction
[0015] Such as figure 1 , figure 2 and image 3 As shown, the animal centrifuge video acquisition system at least includes a centrifuge shaft 12, a centrifuge shaft drive mechanism 14, and the centrifuge shaft 12 is vertically connected with the centrifuge arm 7, so that the centrifuge arm 7 and the centrifuge base 16 Parallel, the other end of the horizontal centrifuge arm 7 fixes the animal experiment platform 15, and the camera of a wireless camera unit is fixed on the horizontal centrifuge arm 7 near the position of the centrifuge rotating shaft 12, and the camera focuses on the animal experiment platform 15, and the wireless camera The unit 5 is used to extract the animal image information of the fixed animal experiment platform 15, and transmits it to a control computing unit 13 by wireless mode. When the fixed animal experiment platform 15 at one end rotates centrifugally around the axis, the control calculation unit 13 receives, stores and analyzes the image informa...

The invention belongs to medical experiment equipment, in particular to an animal centrifuge video capture system which is characterized by at least comprising one centrifuge rotating shaft and a centrifuge rotating shaft driving mechanism. The centrifuge rotating shaft is vertically connected with a centrifuge rotating arm, so that the centrifuge rotating arm is parallel to a centrifuge base, and the other end of the horizontal centrifuge rotating arm is fixed on an animal experiment platform. A camera of a wireless camera unit is fixed to the position on the horizontal centrifuge rotating arm, adjacent to the centrifuge rotating shaft, the camera is focused on the animal experiment platform, and the wireless camera unit is used for extracting the animal image information of the fixed animal experiment platform. When the centrifuge rotating shaft driving mechanism drives the centrifuge rotating shaft to rotate, the centrifuge rotating shaft drives the fixed animal experiment platform at the other end of the centrifuge rotating arm to rotate around the shaft, a control calculation unit receives, stores and analyzes the animal image information, and judges whether the animal loses consciousness or not. The invention provides a basis for the physiological mechanism and the prevention and the treatment of brain injury caused by positive acceleration.
Description
technical field [0001] The invention belongs to medical experiment equipment, especially an animal centrifuge video acquisition system, which establishes a rat model of brain injury caused by positive acceleration generated by the centrifuge by observing the performance of rats in the animal centrifuge, including rats Design of special fixtures and analysis of computer image acquisition. Background technique [0002] When fighter jets do maneuvers or aerobatics, the direction of the centripetal acceleration produced is directed from the bottom of the cockpit to the canopy. In the case of this accelerated movement, the pilot must be subjected to the inertial centrifugal force opposite to the acceleration, and its direction is directed from the head to the pelvis (foot). In aviation medicine, this acceleration is called positive acceleration, and the inertial force experienced by the pilot is expressed as +Gz. In recent years, high-performance fighter jets can produce high G...
