Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to a portable oral mucosa sampler. Background Technology

[0002] The portable oral mucosal sampler is a lightweight tool designed for convenient collection of oral mucosal cells. Its main body is made of medical-grade ABS material, and it is equipped with a soft and sterile polyester fiber sampling head. It can safely and efficiently obtain oral epithelial cell samples. No professional training is required for operation. Users only need to gently scrape the cheek with the sampling head 10-15 times to complete the non-invasive sampling. The whole process is painless and takes no more than 1 minute. It generally consists of a handheld sampling rod, a polyester fiber sampling head that comes into contact with the oral mucosa, and a sampling tube that contains the above two parts.

[0003] Existing application number: CN201820490620.1, this utility model discloses an oral mucosal sampler for gene detection, including a fixed plate. A movable plate is slidably connected to one side of the fixed plate via a slide rail. Two support plates are installed at one end of each of the two movable plates. Sponges are installed inside each of the four support plates, and filter plates are fixed to one side of each of the four support plates. Folding plates are rotatably connected to each pair of the four support plates, with two folding plates installed in total. Iron plates are fixed to one end of each of the two folding plates, and magnets are fixed to one side of each of the two iron plates. A first bolt rotatably connects the two movable plates, and a clamping plate is fixed above one of the movable plates. The clamping plate and the first bolt are rotatably connected by threads. Fixing boxes are installed outside each of the two fixing holes. This utility model, with its support plates and sponges, avoids the problem of easy shaking and saliva leakage when the mouth is open for a long time during sampling.

[0004] Based on the above, the sampling rods are generally quite long. To facilitate the preservation and storage of the sampled specimens, after sampling is completed, the operator needs to manually break off the sampling rod above the sampling ball and place it into the storage container or testing container. During this process, the hands are likely to come into direct contact with the sample, making it impossible to achieve contactless separation and independent sealing of the sampling head, which increases the risk of contamination. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a portable oral mucosal sampler. This solves the problem that existing sampling rods are generally too long, requiring operators to manually break off the sampling rod above the sampling bulb and place it into a storage or testing container after sampling to facilitate specimen preservation. During this process, the operator's hand can easily come into direct contact with the sample, making it impossible to achieve contactless separation and independent sealing of the sampling head, thus increasing the risk of contamination.

[0006] The purpose and effectiveness of this portable oral mucosa sampler are achieved through the following specific technical means: A portable oral mucosa sampler includes a storage bottle, a first threaded groove, a handheld part, an insertion part, a contact part, a sampling ball, a sampling facilitator, and a storage facilitator. The first threaded groove is formed on the inner side of the top of the storage bottle. The handheld part is located on the right side of the storage bottle. The insertion part is inserted into the inside of the handheld part. The contact part is located below the insertion part. The sampling ball is fixedly connected to the bottom of the contact part. The sampling facilitator is located inside and outside the handheld part. The storage facilitator is located at the top and bottom ends of the storage bottle.

[0007] Furthermore, the sampling-facilitating component includes: anti-slip texture; multiple anti-slip textures are provided, and the multiple anti-slip textures are dispersedly and fixedly connected to the outside of the handheld part.

[0008] Furthermore, the sampling assembly also includes a contraction ring and an expansion ring; the contraction ring is fixedly connected to the bottom of the handheld part; and the expansion ring is fixedly connected to the top of the insertion part.

[0009] Furthermore, the sampling component also includes: an upper cap and a first threaded ring; the upper cap is disposed above the storage bottle; the first threaded ring is fixedly connected to the bottom of the upper cap, and the first threaded ring is threadedly connected to a first threaded groove.

[0010] Furthermore, the easy-to-store component includes: a breakable part and an operating plate; the upper end of the breakable part is fixedly connected to the lower part of the extension part, and the lower end of the breakable part is fixedly connected to the upper part of the contact part; two operating plates are provided, and the two operating plates are separately fixedly connected inside the upper cover.

[0011] Furthermore, the easy-to-store component also includes: a second threaded ring, a lower cap, and a second threaded groove; the second threaded ring is fixedly connected to the bottom of the storage bottle; the lower cap is disposed at the bottom of the second threaded ring; the second threaded groove is formed inside the lower cap, and the lower cap is threadedly connected to the second threaded ring through the second threaded groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, the traditional sampling rod is designed with a retractable handheld part and an extension part, which effectively solves the storage problem caused by the excessive length of the sampling rod. The length of the storage bottle is greatly shortened, making it easy to store and carry. The overall length can be extended by using the interference fit between the shrink ring and the expansion ring for fixation, making it convenient to use.

[0013] Secondly, after sampling, the broken part is inserted into the gap of the operating plate inside the upper cover, and the sampling rod is automatically broken by tilting and applying force, so that the contact part and the sampling ball fall into the upper cover. Then, the sample is sealed and stored by the threaded connection between the lower cover and the upper cover. This design completely avoids hand contact when manually breaking the sampling rod. The mechanical structure realizes the automatic separation and sealing of the sample, eliminating the risk of contamination from the operation process and improving the safety and storage efficiency of sample preservation.

[0014] This invention significantly shortens the storage length through a retractable handheld part and an extension part structure, achieving a balance between portability and ease of use. With the linkage design of the break-off part and the operation panel, as well as the threaded sealing structure of the upper and lower caps, the sampling head can be separated and sealed without contact. This eliminates the risk of sample contamination from the source of operation and improves storage efficiency, promoting the upgrading of sampling equipment towards portability and low-contamination sampling process, and contributing to the positive development of the oral mucosa testing field.

[0023] The sampling component includes: anti-slip texture 201; multiple anti-slip textures 201 are provided, and the multiple anti-slip textures 201 are dispersedly and fixedly connected to the outside of the handheld part 2.

[0024] The sampling component also includes a contraction ring 202 and an expansion ring 5; the contraction ring 202 is fixedly connected to the bottom of the handheld part 2; and the expansion ring 5 is fixedly connected to the top of the insertion part 3.

[0025] The sampling component also includes: an upper cap 7 and a first threaded ring 701; the upper cap 7 is positioned above the storage bottle 1; the first threaded ring 701 is fixedly connected to the bottom of the upper cap 7 and is threadedly connected to the first threaded groove 101.

[0026] The specific usage and function of this embodiment are as follows: Before use, the upper cap 7 is threadedly connected to the storage bottle 1 through the first threaded ring 701 and the first threaded groove 101 to seal the storage bottle 1. The handheld part 2, the insertion part 3, the contact part 4, the sampling ball 401 and other components are installed inside the storage bottle 1. When in use, the handheld part 2 is taken out of the storage bottle 1, and then the bottom of the insertion part 3 is pulled down to expose the part of the handheld part 2. The insertion part 3 is pulled out from the handheld part 2. When the expansion ring 5 is pulled to the position of the contraction ring 202, the expansion ring 5 and the contraction ring 202 made of plastic form an interference fit connection, keeping the expansion ring 5 and the contraction ring 202 in the extended state. Then, the staff can hold the handheld part 2 and insert the insertion part 3, the contact part 4 and the sampling ball 401 into the patient's mouth to sample the oral mucosa. During the process, the anti-slip texture 201 can increase the friction between the staff and the handheld part 2, ensuring that the sampling process is carried out smoothly.

[0027] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes a storage component, which is set at the top and bottom of the storage bottle 1.

[0028] The easy-to-store components include: a breakable part 6 and an operating plate 8; the upper end of the breakable part 6 is fixedly connected to the lower part of the extension part 3, and the lower end of the breakable part 6 is fixedly connected to the upper part of the contact part 4; two operating plates 8 are provided, and the two operating plates 8 are separately fixedly connected inside the upper cover 7.

[0029] The storage component also includes: a second threaded ring 102, a lower cap 9, and a second threaded groove 901; the second threaded ring 102 is fixedly connected to the bottom of the storage bottle 1; the lower cap 9 is located at the bottom of the second threaded ring 102; the second threaded groove 901 is opened inside the lower cap 9, and the lower cap 9 is threadedly connected to the second threaded ring 102 through the second threaded groove 901.

Then, the upper cover 7 is removed, and the sampling ball 401 is inserted into the upper cover 7. Then, the breaking part 6 connecting the insertion part 3 and contact part 4 is inserted into the gap between the two operating plates 8. The operator tilts their hand and applies force to break the breaking part 6. The contact part 4 and sampling ball 401 fall into the upper cover 7 due to gravity. Then, the hand part 2 and the insertion part 4 are inserted into the upper cover 7. Part 3 can be discarded immediately; then, the lower cap 9 is removed from the bottom of the storage bottle 1 through the threaded connection mechanism formed by the second threaded groove 901 and the second threaded ring 102. The second threaded groove 901 in the lower cap 9 is threadedly matched and assembled with the first threaded ring 701 in the upper cap 7. The contact part 4 and the sampling ball 401 can be sealed and stored in the space after the upper cap 7 and the lower cap 9 are connected. The entire process does not require the operator's hands to come into contact with the contact part 4 and the sampling ball 401 after sampling, which is more hygienic and clean.
