This invention discloses a fixation device for animal medical experiments, comprising a support frame, a square tube fixedly connected to the bottom of the support frame, a first motor fixedly connected to the side of the square tube, a one-way
threaded rod fixedly connected to the output end of the first motor, a sliding frame threadedly connected to the one-way
threaded rod, a connecting rack fixedly connected to one side of the sliding frame, and an external toothed
ratchet ring meshing with the connecting rack. The support frame is fixedly connected to a first
bevel gear, and a disc is fixedly connected to the side of the first
bevel gear away from the support frame. This invention effectively avoids experimental interference caused by
blood stains and odors, ensuring
data accuracy. The device features an automatic post-experiment cleaning mechanism that quickly cleans
blood stains and odors from components such as the support frame and flip clamp, preventing residual odors from irritating subsequent experimental animals, reducing abnormal reactions such as animal restlessness and stress, stabilizing physiological indicators such as
heart rate and
blood pressure, and ensuring the accuracy and consistency of data from multiple batches of experiments.
