Description

Technical Field

[0001] The utility model belongs to the technical field of oral sampling devices, and particularly relates to an oral sampling device. Background Art

[0002] The existing oral sampling device is a device used to extract the mucous membrane inside the oral cavity for testing. The device is a kind of medical device with a simple structure and is easy to operate by hand-held sampling. When sampling, the existing oral sampling device directly grasps the handpiece to take the sampling rod and the sampling cotton ball for operation. It is inconvenient to separate the hand from the oral cavity for hygienic sampling when sampling. At the same time, it is easy to press and install when the protective cover is closed, and it is easy to loosen and be unstable when placed. After sampling, the sampling cotton ball is directly placed in the sampling placement bottle, which is not easy to control stably and is easy to cause the sample to shake, affecting the detection effect after sampling. For this reason, we propose an oral sampling device. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 5 The top of sampling rod 4 is provided with a hand-held head 1, which is convenient for holding the sampling rod 4 and using it. The bottom end of sampling rod 4 is wrapped with a sampling cotton ball 7, which is convenient for sampling. The end surface of sampling rod 4 is clamped and installed with a protective cover 2, which is convenient for separating hands from the oral cavity during sampling and easy for hygienic sampling. The inner surface edge of the protective cover 2 is fixed with an elastic protrusion 8 by glue. The end edge of the sampling placement bottle 3 is provided with a pressing groove 9, and the protective cover 2 and the sampling placement bottle 3 are tightly connected by the elastic protrusion 8 and the pressing groove 9, which is easy to press and fix the protective cover 2 and the sampling placement bottle 3 after sampling, so as to facilitate closed protection use.

[0021] In this embodiment, preferably, the inner bottom end of the sampling bottle 3 is snap-fitted with a control bottom block 5, which is easy to snap-fit and place when the sampling cotton ball 7 is placed. The inner surface of the control bottom block 5 is fixed with a built-in sample protection sheet 6 by glue, which is convenient for protection after the sampling cotton ball 7 is taken. The end of the sampling cotton ball 7 is embedded in the interior of the control bottom block 5, which is easy to protect after sampling, thereby improving the detection effect after sampling.

[0022] In order to facilitate the locking and protection of the sampling cotton ball 7, the built-in sample protection sheet 6 is an arc-shaped structure, and the built-in sample protection sheet 6 is embedded in the interior of the control bottom block 5. In order to facilitate the sampling cotton ball 7 to be placed more stably, the outer surface of the control bottom block 5 coincides with the inner bottom end of the sampling placement bottle 3, and the outer surface of the sampling cotton ball 7 coincides with the inner surface structure of the control bottom block 5. In order to facilitate the protection cover 2 and the sampling placement bottle 3 to be pressed tightly for protection, the pressing groove 9 and the sampling placement bottle 3 are an integrated structure, and the elastic protrusion 8 matches the inner surface structure of the pressing groove 9. In order to facilitate easy protection after closing, the protective cover 2 is a circular structure, and the end of the sampling placement bottle 3 is embedded in the interior of the protective cover 2.

[0023] The working principle and use process of the utility model are as follows: the oral sampling device can be used by directly disassembling the protective cover 2 and the sampling bottle 3 when in use, and the handheld head 1 can be taken to drive the sampling rod 4 and the sampling cotton ball 7 to take samples. When sampling, the sampling cotton ball 7 and the end of the sampling rod 4 are embedded in the interior of the oral cavity, and the protective cover 2 contacts the surface of the oral cavity, which is convenient for separating the hand from the oral cavity through the protective cover 2, making it difficult to contact the oral cavity during sampling, and making sampling more hygienic. After sampling, the protective cover 2 is directly closed on the surface of the sampling bottle 3 so that the sampling cotton ball 7 and the sampling rod 4 are in contact with each other. The sampling rod 4 is placed inside the sampling placement bottle 3, and the elastic protrusion 8 is deformed to squeeze the elastic protrusion 8 inside the pressing groove 9, which makes it easy to fix the protective cover 2, and facilitate the stable placement of the sampling rod 4 and the sampling cotton ball 7 after sampling, and easy to fix. Then, when the sampling rod 4 and the sampling cotton ball 7 are closed, the end of the sampling cotton ball 7 is embedded in the interior of the control bottom block 5 and protected by the built-in sample protection sheet 6. The built-in sample protection sheet 6 is not easy to cause surface contamination of the sampling cotton ball 7, and it is stably engaged and placed, which is convenient for protecting the sampling cotton ball 7 after sampling, thereby improving the detection effect after sampling.
