Device for trauma stress experiment

Abstract

The invention relates to a device for a trauma stress experiment. The device for the trauma stress experiment comprises a box body and a control system. Slots are arranged on the inner lateral side of the box body, two ends of a longitudinal plate and two ends of a transverse plate are respectively in inserting connection with the slots, and the longitudinal plate and the transverse plate are intersected and matched. A fence and a through air are arranged on the inner side of a base plate of the box body, and a shake generator and a gas generator which are electrically connected with the control system are fixed on the outer side of the base plate. A collecting plate is arranged at the bottom of the box body, a loudspeaker is installed on one side wall of the box body, and a current stimulating drive is installed on the other side wall. A noise drive, a camera and a light stimulating source are installed on the top plate. The noise drive is electrically connected with the loudspeaker, and a current generator is electrically connected with the fence. The control system comprises a computer, a single chip microcomputer, a programmable logic device, a photoelectric isolating circuit, the current stimulating drive, a light source drive and the noise drive. The device for the trauma stress experiment can provide various traumatic stress environments, is conveniently suitable for experimental subjects with different sizes, simultaneously performs one stress mode or various stress modes, and can perform real-time analysis or ex-post analysis.

[0001] The invention relates to an experimental instrument, in particular to a device for trauma stress experiment. Background technique

[0002] Stress refers to the non-specific systemic reaction that occurs when the body is stimulated by various internal and external environmental factors. Stress sources that cause stress include physiological factors, environmental factors, and psychological, social and cultural factors. The body self-regulates through physiological and behavioral cognitive responses to maintain the stability of the internal environment and normal functioning. But when stress is insufficient, excessive, or prolonged, it can negatively affect body function. In recent years, with the occurrence of "911", "SARS", tsunami, earthquake, Iraq war, Wenchuan earthquake, major traffic accidents and other sudden disasters, mental disorders caused by various traumatic stresses remain high. Current studies have confirmed that excessive stress, espec...
