Abstract
A portable sow pupillary reflex detecting device relates to a detecting device and aims at solving the problem that no detecting instrument for detecting sow health condition reflected by sow pupils exists at present. A power supply and a drive control circuit are installed at the bottom in a box body, an adjusting knob and a power supply switch button are arranged on the outer side of the top, a radiationlight source and six infraredlaser heads are all fixed on a laser head fixing plate, and the radiationlight source is located at the central position of a regular hexagon formed by the six infraredlaser heads. The six infrared laser heads are divided into three groups, light rays emitted by every two adjacent infrared laser heads are intersected and converged into a point in the space, the control signal output end controlling the knob is connected with the control signal input end of the drive control circuit, the radiationlight sourcecontrol signal output end of the control circuit is connected with the control signal input end of the radiation light source, and the control signal output ends for the six infrared laser heads of the control circuit are respectively connected with the control signal input ends of the six infrared laser heads. The portable sow pupillary reflex detecting device is used for detecting sow pupils.
Description
technical field [0001] The invention relates to a detection device. Background technique [0002] The function of pupil contraction under light stimulation is called pupilreflex or response to light. The pupil will shrink immediately under strong light stimulation, and maintain it for a while, and then slowly dilate. The speed and degree of pupillary reactions on both sides are exactly the same, that is, the same amplitude changes at the same time. The pupillary response is slow or disappears is pathological. [0003] In the process of human medical clinical and experimental research, the inspection process of pupillary reflex includes direct response to light, indirect response to light and convergence reflex. In the detection of pupillary reflex, the test results may be affected by stress, or the measurement results may have large errors due to failure to cooperate with the inspection; the application of human pupil detection instruments to animals often has many proble...
