A criminal crime scene refers to a place or location where a criminal suspect crimes and leaves a trace, material evidence, related to the crime. The discovery and extraction of biological material evidence is an important ring in crime scene investigation, is the most critical step of subsequent laboratory inspection, can provide powerful evidence for case detection, and is an important means for detecting and solving cases at present.

At present, different extraction methods are generally adopted for trace biological material evidence on different objects in the field. The method is characterized in that a wiping method and a sticking method are usually adopted for the exfoliated cells, the wiping method is to wipe the parts possibly left by the material evidence after a cotton swab is soaked by normal saline, but on one hand, the method is easily influenced by the wiping strength of an extractor and the adhesive force of cotton swab fibers, and on the other hand, for the detection materials such as bed sheets and clothes, the wiping method has a small wiping area and insufficient viscosity, so that the number of the extracted exfoliated cells is insufficient, and therefore, the cotton swab wiping method is not suitable for extracting the biological material evidence on the rough objects. The existing adhesive device for adhering the exfoliated cells is generally composed of a base with an adhesive layer and a cover. The adhesive layer is composed of a whole or two symmetrically arranged D-shaped sterile neutral adhesive tapes, and in practical application, due to the viscosity of the adhesive tapes, the adhesive tapes are easy to curl and wind in the transfer process after being adhered, so that the extraction efficiency of the exfoliated cells adhered on the adhesive tapes is seriously influenced.
