Abstract
Description
Technical Field
[0001] This invention relates to the technical field of toolboxes, and in particular to a multifunctional forensic toolbox and its method of use. Background Technology
[0002] For on-site medical investigation, medical tracking and evidence collection, live medical examination and observation of injuries, autopsy, symptom analysis, test comparison, observation and interrogation, identification of remains, retrieval of surveillance footage, and special physical examinations, forensic doctors need to bring specific investigation tools to the scene. Some scenes are quite chaotic, and the tools used for investigation and sampling are different. In addition, samples are sometimes collected from living tissues at the investigation site. The collected samples and investigation tools are often placed separately, which means that forensic doctors need to carry at least two or more sets of toolboxes when going to the scene for investigation work. This is very inconvenient and cannot effectively maintain the freshness of live samples. After the autopsy, instruments are often simply rinsed with tap water at the scene and then directly packed into boxes. They are then processed separately in the laboratory using various equipment such as fixed ultrasonic cleaners, sterilizers, and drying ovens. Instruments need to be transferred multiple times between the "scene-transportation-laboratory", which is cumbersome and carries a high risk of contamination and cross-infection.
