Description

Technical Field

[0001] The invention belongs to the technical field of oral sample storage devices, and in particular relates to an oral sample storage device for stomatology. Background Art

[0002] Dentistry, also known as oral medicine or oral clinical medicine, is an important branch of medicine that focuses on the study, diagnosis and treatment of human oral and maxillofacial diseases. This discipline covers multiple subfields, including oral medicine, oral surgery, oral rehabilitation, orthodontics, pediatric dentistry, oral preventive care, and oral and maxillofacial medical imaging.

[0003] Oral samples are of great value in medical research and clinical diagnosis, and can be used in genetic testing, disease diagnosis, microbial analysis and many other aspects. The types of oral samples include saliva samples, soft tissue samples and hard tissue samples. The methods for collecting oral samples include supragingival plaque collection and subgingival plaque collection in hard tissue sample collection.

[0004] The oral sample preservation device is a special container used to store and preserve oral samples (such as oral mucosal cells, saliva, etc.), ensuring that the samples can maintain their integrity and stability after collection for subsequent analysis and research. The main components are sampling swabs, collection preservation tubes and preservation fluids. Oral sample preservation devices are widely used in hospitals, scientific research institutes, testing institutions and other places for oral microbial research, genetic testing, disease diagnosis and other fields. By collecting and analyzing oral samples, we can understand the individual's oral health status, microbial community distribution and potential health risks.

[0005] The authorization publication number "CN210492330U" records that "a special storage tube for oral samples includes an outer tube and a tube cover, the inner wall of the outer tube is fixedly connected with a plurality of fixed blocks, the sides of the plurality of fixed blocks away from the outer tube are fixedly connected with the inner tube, a circular through hole is opened on the lower surface of the outer tube, and the hole wall of the circular through hole is movably connected with a moving mechanism, the outer wall of the outer tube is fixedly connected with a symmetrically distributed disinfection mechanism, and the outer wall of the outer tube is fixedly connected with two symmetrically distributed fixing mechanisms; the fixing mechanism includes an L-shaped rod fixedly connected to the side wall of the outer tube, and the bottom end of the L-shaped rod is fixedly connected with a pointed head. The special storage tube for oral samples of the utility model saves time and effort in the process of taking out oral samples, reduces the difficulty of medical staff in taking oral samples, and at the same time improves the efficiency of oral sample detection, and can also effectively improve the accuracy of oral sample detection".

[0006] The above patent is provided with a connecting rod, a rubber piston, a first mesh plate and a second mesh plate. When it is necessary to take out oral samples for testing, the moving mechanism is raised so that the oral samples are attached to the first mesh plate and the second mesh plate. After that, the medical staff only needs to use tweezers to clamp the oral samples. The oral sample removal process saves time and effort, reduces the difficulty of medical staff in taking oral samples, and improves the efficiency of oral sample testing. However, in the actual oral sample collection process, the existing oral sample preservation device cannot perform targeted collection of dental plaque in the gaps between teeth, resulting in the oral samples collected in the oral cavity unable to accurately reflect the pathogenic environment in the oral cavity, resulting in a decrease in the accuracy of oral environment analysis, and the preservation liquid is not completely isolated from the air, resulting in the preservation liquid being contaminated by environmental pathogens when the oral samples are collected, which reduces the accuracy of the subsequent oral sample analysis data. For this reason, we propose an oral sample preservation device for stomatology. Summary of the invention
