Core Technical Parameters

Practical Application Cases

1. A municipal forensic authentication center accepted the entrustment of the local public security bureau to conduct forensic identification of the injury degree of the victim in an intentional injury case. In the case, the victim was slapped on the left ear by others, resulting in left ear pain and hearing loss. The clinical diagnosis was traumatic tympanic membrane perforation. The two parties had major disputes on whether the tympanic membrane perforation was caused by the trauma and the size of the perforation and the injury degree. Moreover, the victim's tympanic membrane perforation was located at the edge of the tense part of the tympanic membrane, with a very small volume. It was difficult to clearly present the perforation shape and fresh injury characteristics by naked eye observation and ordinary otoscope examination. The traditional photography method could not obtain clear image data that met the identification requirements, and the identification work encountered a bottleneck.
    
   The appraisers used this Forensic Clinical Digital Examination and Forensics System to carry out high-power magnification inspection of the victim's left ear tympanic membrane through the digital otoscope. Through the optimized lighting of 8 adjustable warm white LED lights, they clearly presented the micro perforation shape of the tympanic membrane tense part, the fresh bleeding points at the edge, and the congestion and edema of the tympanic membrane and other fresh traumatic injury characteristics. At the same time, through the high-definition imaging function of the system, they completely recorded the whole inspection process, took high-resolution photos of the perforation characteristics, and accurately measured the diameter and area of the perforation. Through the purple light auxiliary mode of the system, they confirmed the occult submucosal hemorrhage around the perforation, and clarified that the perforation was a fresh traumatic perforation, which had a direct causal relationship with the slapping trauma.
    
   Finally, based on the objective image data collected by the system, the appraisers issued a forensic appraisal opinion of minor injury grade II, which was fully accepted by the People's Court and became the core evidence for the conviction and sentencing of the case. The image data collected by the system was also included in the case file as an attachment to the appraisal opinion, providing a solid scientific basis for the fair trial of the case.
    
2. The Criminal Technology Corps of the Provincial Public Security Department accepted a major case of sexual assault on a minor. The victim was a young girl, and the victim was extremely emotionally unstable after the incident, unable to cooperate with the traditional invasive examination. Moreover, the mucosal injury of the victim's perineum was extremely subtle, which could not be identified by naked eye observation. The traditional photography method could not clearly fix the injury characteristics, and could not provide effective evidence support for the case, so the investigation of the case fell into a deadlock.
    
   The forensic examiners used this Forensic Clinical Digital Examination and Forensics System, adopted a non-invasive inspection method, and carried out non-invasive inspection of the victim's perineal and perianal skin and mucous membranes through a digital dermatoscope and a high-power magnification microscope. Through the white light + purple light dual light source lighting mode, they clearly found and recorded three subtle epidermal exfoliation, occult submucosal hemorrhage points, and secretion attachment traces of the victim's perineal mucosa. The whole process was non-contact and non-invasive, which maximally protected the physical and mental health and privacy of the victim. At the same time, through high-definition video and photos, the shape, position, size and characteristics of the injury were completely fixed.
    
   Based on the objective image data collected by the system, the forensic doctor issued a forensic appraisal opinion, which confirmed that the victim had fresh body surface injury caused by sexual assault, provided key core evidence for the characterization of the case and the determination of criminal facts, and finally successfully locked and severely punished the suspect, effectively safeguarding the legitimate rights and interests of minors.
