Oral mucosa sampling device

Abstract

The invention discloses an oral mucosa sampling device, and relates to the technical field of medical auxiliary equipment, the oral mucosa sampling device comprises a sampling tube and an operation cylinder, the left end of the operation cylinder is rotatably connected with a rotating wheel, the right end of the operation cylinder is provided with a rectangular insertion cylinder, the right side of the rotating wheel of the insertion cylinder is fixedly connected with a rotating tube, and the right end of the rotating tube is rotatably connected with a coaxial ball nut; the left end of the screw rod penetrates through the rotating pipe and the rotating wheel, the right end of the screw rod is provided with an elastic drag hook, the upper side of the right end of the inserting cylinder is provided with an opening, the left end of the sampling pipe is fixedly provided with an inserting piece, the right end of the sampling pipe is provided with a cap, a rubber block is slidably connected into the sampling pipe, and a swab is inserted into the middle of the rubber block. A buckle matched with the elastic drag hook is arranged on the left side of the rubber block. According to the technical scheme, the sampling success rate can be increased through the spiral bristles; the sampling swab can be quickly replaced and the swab after sampling can be stored, the effectiveness of the sample can be prolonged, the concentrated placement can also play a role in single isolation, and cross infection is avoided.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an oral mucosa sampling device. Background technique [0002] Collecting oral exfoliated cells for DNA testing is a non-interventional, painless, and non-invasive method that is easy to operate and does not require disinfection. At present, more and more units at home and abroad use the oral exfoliation of detainees and criminal suspects with criminal records. Cells are tested for forensic DNA and a DNA database is established. In addition, in conventional medical diagnosis, it is also possible to diagnose diseases by collecting oral exfoliated cells and analyzing their gene fragments, and plan treatment plans for patients. When sampling, sampling tools must be used to sample oral mucosal cells, and the cells are stored in slides, specific containers or solutions, and then transferred to the laboratory for inspection and analysis. Existing oral cavity samplin...

Problems solved by technology

[0003] The current swabs generally have the following disadvantages: First, the surface area of ​​the cylindrical swab head is limited. When collecting exfoliated cells in the oral cavity, the number of cells removed is limited, which is likely to cause inaccurate test results. For subsequent cell extraction and DNA extraction The application is limited; the second is that in the actual operation of oral sampling, multiple individuals are often extracted and sent for testing uniformly, resulting in samples that cannot be used in a timely manner, and long-term retention will inevitably lead to fungal and bacterial contamination that will affect the test results. They are all placed in one place uniformly, and there is also the possibility of cross-infection, which will damage the sample and affect the test results
