Sampler 100 may be used to house swab 200 in first chamber C, and first chamber C may similarly house reagents such as saline to pre-treat swab 200. The second chamber D is used for filling and sampling, and the liquid reagents in the first chamber C and the second chamber D can flow between the two chambers. The first opening and the second opening K can directly communicate the first cavity C and the second cavity D with the outside respectively.

In sampler 100, a swab 200 after sampling is placed in the first chamber C, and a treatment reagent such as physiological saline is injected through the first opening or the second opening K. The swab 200 is pre-treated in the first chamber C to allow the sample from the swab 200 to be eluted into the reagent. Since the first chamber C is communicated with the second chamber D, the reagent containing the sample can flow between the first chamber C and the second chamber D, so that the operator can directly collect the sample reagent in the second chamber D through the second opening K or perform the instrument detection on the sample reagent without taking out the swab 200. The operation of taking out the swab 200 is avoided, so that the steps are simplified, and the risk of polluting the experimental environment caused by taking out the swab 200 is avoided.

It can be understood that, according to different usage scenarios and usage requirements, the number of the first cavities C and the second cavities D may be adaptively adjusted, and specifically, a plurality of first cavities C correspond to one second cavity D, a plurality of first cavities C correspond to a plurality of second cavities D, or a plurality of first cavities C correspond to a plurality of second cavities D, and the like, which is not limited herein.

In some embodiments, body 10 includes a first tube portion 11 and a second tube portion 13 having axes that do not coincide with each other, a first cavity C being formed in first tube portion 11, and a second cavity D being formed in second tube portion 13.

In one embodiment, the first chamber C is substantially cylindrical, the second chamber D is substantially rectangular, and the first pipe portion 11 and the second pipe portion 13 are correspondingly shaped and arranged side by side with their axes parallel. It will be appreciated that in other embodiments, the specific shapes of the first chamber C, the second chamber D, the first pipe portion 11 and the second pipe portion 13 can be adjusted, and the axes of the first pipe portion 11 and the second pipe portion 13 are not limited to being parallel, and the axes of the two may be at an angle to each other for the purpose of facilitating the liquid extraction operation or the direct detection of the instrument, and the like, and are not limited in detail herein.

Further, the first pipe portion 11 and the second pipe portion 13 together constitute a bottom 15 of the sampler 100 at one end on their own axis, and a first opening and a second opening K are formed respectively at the other end on their own axis, and the second opening K is lower than the first opening in the height direction.

The first pipe part 11 and the second pipe part 13 bottom parallel and level are convenient for steadily placing, and the second pipe part 13 is because mainly undertake functions such as annotating liquid, sample, so the second opening K is relatively closer to the bottom 15 of the ware to reduce annotate the liquid stroke, also be closer to the liquid level during the sample, the operation of being convenient for.

Furthermore, the first pipe portion 11 and the second pipe portion 13 have a common pipe wall 16, and the common pipe wall 16 is provided with a communication hole for communicating the first chamber C with the second chamber D.

The first pipe portion 11 and the second pipe portion 13 are directly connected by sharing part of the pipe wall, the structure is compact, and the first cavity C and the second cavity D can be directly communicated by opening on the common pipe wall 16. In order to reduce the liquid requirement for the first chamber C to communicate with the second chamber D, the communication hole should be located as close as possible to the bottom 15 of the container.

Specifically, the body 10 further includes a screen 17, and the screen 17 is provided at a communication portion between the first chamber C and the second chamber D and covers the communication hole.

It will be appreciated that in other embodiments, the filtering function may be provided directly by configuring the communication holes in the form of a plurality of fine holes without an additional screen 17.

In some embodiments, the inner wall of the first chamber C is provided with a plurality of elution structures 19 that are raised with respect to the inner wall.

The elution structure 19 may interact with the swab 200 disposed in the first chamber C to facilitate the detachment of the sample component from the swab 200 when the swab 200 collides with the protruding elution structure 19, especially when the swab 200 is rotated, thereby increasing the elution rate. The first tube part 11 may be made of a hard plastic.

Further, the elution structure 19 is located at the bottom of the first cavity C away from the opening and is a rib-like protrusion.

Since the injected reagent, such as saline, is located at the bottom of the first chamber C and the swab 200 is mostly located there in its inserted position, the elution structure 19 is configured in the first chamber C away from the opening, i.e. close to the bottom wall, to most effectively come into contact with the swab 200, while the ribbed structure also facilitates scraping of the swab 200. It will be appreciated that the elution structure 19 may be configured in other shapes or in a variety of different shapes, and the configuration location may be adapted according to the position of the swab 200, so long as the elution rate is effectively increased, and is not particularly limited herein.

Referring to fig. 4, in some embodiments, the sampler 100 further includes a first cover 30, the first cover 30 can be covered on the first opening in an opening-closing manner, and is provided with a rotating hole Z, and the rod portion of the swab 200 is inserted through the rotating hole Z and can rotate around its own axis in the rotating hole Z.

It will be appreciated that the second opening K may also be closed by providing a second cap or film, in which case the sample may need to be taken off the cap or by piercing the sample.

Further, the side of the first cover 30 facing the first chamber C is configured with a guide structure 31 guiding the swab 200 through the rotation hole Z.

The general operation of the swab 200 after sampling is to insert the swab 200 into the first chamber C and then to cover the first cover 30. The guide structure 31 can guide the swab 200 when the first cover 30 is closed, so that the rod portion can be accurately inserted into the rotating hole Z, thereby reducing the difficulty in mounting the first cover 30.

Referring to fig. 5, some embodiments of the present invention further provide a swab 200, the swab 200 is used in the sampler 100, the swab 200 has a sampling end 201 and a handle end 203, the handle end 203 is configured to penetrate the first cover 30, and the peripheral structure has a boss 205 located on one side of the first cover 30 facing the first cavity C.

After the swab 200 is completely sampled and inserted into the first cavity C of the sampler 100, the first cover 30 is covered, the sampling end 201 of the swab 200 abuts against the bottom wall of the first cavity C, and the handle end 203 is limited by the boss 205, so that the swab 200 can be effectively prevented from moving up and down in the axial direction.

The perimeter of the handle end 203 of the swab 200 is configured with at least one plane P.

The plane P is configured at the handle end 203 to facilitate application of rotational torque by hand or a specialized rotational machine in performing the operation of rotating the swab 200. In one embodiment, the handle end 203 is configured with two planes P that are parallel and spaced apart, it being understood that in other embodiments, the number and angle of the planes P may be varied, simply to facilitate the application of torque.

When the sampler 100 and the swab 200 are used, an operator first collects a sample to be tested through the swab 200, then inserts the collected swab 200 into the first cavity C of the collector, and covers the first cover 30. At this time, the sampling end 201 of the swab 200 contacts the elution structure 19, the rotation of the swab 200 is driven by the rotation of the handle end 203, and the sample to be tested is eluted into the reagent such as the saline injected into the first cavity C under the scraping of the elution structure 19. After the elution, which is a pretreatment, is completed, the sampler 100 is placed in the inspection apparatus, and the sampling needle of the inspection apparatus samples the sample into the second cavity D through the second opening K. Because the second cavity D that the work of taking a sample was located separates with the first cavity C that swab 200 was located, and does not share an opening, so both can mutual noninterference, need not during the sample to first opening uncap and take out swab 200, and the operation is more convenient, and relatively more seals stably. When sampler 100 is a disposable device, body 10, first cover 30, and swab 200 may be disposed of for convenient use.
