Special sampling brush for oral cavity

Abstract

The invention discloses a special sampling brush for the oral cavity, and relates to the field of medical apparatus and instruments. A grip comprises a preparation area and an operation area, wherein a preparation groove is arranged on the upper side of the preparation area; the right side of the preparation groove penetrates through the right side of the preparation area; the operation area is fixedly connected to the upper position of the right side of the preparation area; a buffer wheel is arranged at the left end in the operation area; the buffer wheel is fixedly connected with a plurality of L-shaped contact blocks; a plurality of sampling devices are inserted into the preparation groove; each sampling device comprises a sampling pipe and a sampling brush, wherein each sampling brush is arranged in each sampling pipe; a flange is respectively arranged at the openings of the left end and the right end in each sampling pipe; a supporting piece is arranged at the right end of each sampling pipe; each sampling brush comprises a pushing block; the left side of each pushing block is fixedly connected with a swab rod; and spiral bristles are arranged on each swab rod. By use of the technical scheme of the invention, a sampling success rate can be increased through the spiral bristles, a sampling swab can be quickly replaced and the swab after sampling can be stored, the effectiveness of a sample can be prolonged, concentrated placement can also play a role in single isolation, and cross infection is avoided.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a special sampling brush for oral cavity. Background technique [0002] Collecting oral exfoliated cells for DNA testing is a non-invasive, painless, and non-invasive method with simple operation and no need for disinfection. At present, more and more units at home and abroad use oral exfoliated cells of criminal suspects for forensic DNA testing and establish In addition, in routine medical diagnosis, DNA database can also be used to diagnose diseases by taking 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 sampling tools are generally swabs. The swabs include a swab rod and a swab head. The swab he...

AI Technical Summary

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
