Technical Field
The invention relates to the technical field of police equipment, in particular to a portable non-contact handheld rapid drug-related detector with a protective cover hood.
Background
The drug addict is a brain disease patient in the strict sense. The dynamic change process of eyes contains a large amount of scientific information, and scientifically and accurately acquiring the data and effectively analyzing and judging the data are the technical key for defining drug smokers. The pupil responds sensitively to light stimuli, and when illuminated with light (e.g., focused flashlight light), the pupil contracts immediately and returns quickly after the light source is removed. When one side of the pupil is stimulated with light, the side pupil contracts and recovers after the light is removed, known as a direct light reflex. If the two eyes are separated by an opaque object (for example, using a spacer and a palm), when one pupil is irradiated with light, the other pupil is also immediately contracted, which is called indirect light reflection. Typically, the direct and indirect light reflections from both eyes are simultaneous and of equal amplitude. Pupillary light reflex is an unconditional neural reflex process and is difficult to be interfered by subjective factors. The currently known neural transmission pathways for light reflex are: the relaxation of the pupil is governed by the mydriasis muscle, which causes dilation of the pupil and is governed by sympathetic nerves, and the pupillary sphincter, which is excited to constrict the pupil and is governed by parasympathetic nerves. During the miosis phase of the light reflex, parasympathetic innervation occurs, and during the diastole phase and the pupillary dark adaptation, sympathetic innervation occurs.
The suspected drug addict through hole detector is based on the principle for detection, and utilizes the characteristic that opioid drug addicts have specific pupil dynamic change on specific light wavelength and light intensity to quickly detect the physiological dependence degree and the craving degree of the opioid drug addicts and opioid drug addicts.
