Referring to fig. 1 to 5, the present invention provides a swab 10 for cell sampling, the swab 10 for cell sampling includes a handle 100, a sampling tube 200, a sampling mechanism 300, and a sampling head 400. In this embodiment, the handle 100 is a polypropylene handle, and the handle 100 is provided with the anti-slip threads 110, and the anti-slip threads 110 increase the anti-slip performance of the handle 100 and increase the friction force between the handle 100 and the hand. A sliding cavity (not shown) is formed in the central region of the handle 100, a strip-shaped sliding opening 101 is formed in the side wall of the handle 100, and the strip-shaped sliding opening 101 is communicated with the sliding cavity. One end of the handle 100 is connected to one end of a sampling tube 200, and in this embodiment, the sampling tube 200 is a polypropylene tube. The end of the sampling tube 200 far away from the handle 100 is connected with the sampling head 400, and the handle 100 is communicated with the sampling head 400 through the sampling tube 200. In this embodiment, the sampling head 300 is a polypropylene head. The portion of the sampling tube 200 adjacent to the sampling head 400 is provided with a fracture 210. Further, the middle portion of the sampling tube 200 is provided with a breaking port 210 so as to break the sampling tube 200 at different portions according to the amount of the collected liquid sample.

The sampling mechanism 300 includes a slide rod 310, a connecting rod 320, a pressing plate 330, and a piston 340. One end of the sliding rod 310 is connected to the piston 340. The pressing plate 330 is connected to a side wall of the sliding rod 310 at an end thereof remote from the piston 340 by a connecting rod 320. The piston 340 is adapted to the sampling tube 200, and the piston 340 is inserted into the sampling tube 200 and slidably connected to the sampling tube 200. The sliding rod 310 is partially received in the sliding cavity and is slidably coupled to the handle 100. The sliding rod 310 is partially received in the sampling tube 200. The pressing plate 330 is exposed out of the sliding cavity, and the connecting rod 320 passes through the strip-shaped sliding port 101 to be connected with the pressing plate 330.

The sampling head 400 is a hollow ellipsoid, a plurality of sampling holes 401 are disposed on the side wall of the sampling head 400, and further, each sampling hole 401 is uniformly disposed on the sampling head 400. Each sampling hole 401 communicates with the sampling tube 200 through the sampling head 400. One side of sampling head 400 is provided with scraper 410, has seted up sample groove 402 on the scraper 410, and the edges and corners of scraper 410 are the fillet setting. In this embodiment, the scraper 410 is a rectangular plate and the sampling groove 402 has a rectangular cross-section. In another embodiment, the scraper 410 is a triangular plate and the sampling slot 402 is triangular in cross-section. The sampling head 400 is provided with a plurality of soft fan-shaped leakage-proof blocking pieces 420 in each sampling hole 401, in this embodiment, the soft fan-shaped leakage-proof blocking pieces 420 are soft plastic sheets. In other embodiments, the soft fan-shaped anti-leakage blocking sheet is a soft silicone sheet. In yet another embodiment, the soft fan-shaped leak-proof barrier is a soft rubber sheet. The soft fan-shaped leakage-proof baffles 420 are mutually abutted to form a relatively sealed circular partition plate.

In this embodiment, the sampling head 400 is provided with four 90-degree central-angle soft fan-shaped leakage-proof baffles 420 in each sampling hole 401, and the soft fan-shaped leakage-proof baffles 420 are abutted to each other to form a relatively sealed circular partition. In another embodiment, the sampling head is provided with three soft fan-shaped leakage-proof blocking sheets with 120-degree central angles in each sampling hole, and the soft fan-shaped leakage-proof blocking sheets are mutually abutted to form a relatively closed circular partition plate. Under normal conditions, each soft fan-shaped leak protection separation blade mutually supports and constitutes a relative inclosed circular baffle and seals the thief hole 401, and when having strong air current to pass through the thief hole 401, each soft fan-shaped leak protection separation blade is buckled and is made the thief hole 401 be in temporary development state. That is, when the pressing plate 330 is pushed to move the piston 340, the strong airflow generated by the pushing movement adsorbs the liquid sample to pass through the sampling hole 401, so that each of the soft fan-shaped leakage-proof blocking pieces 420 is bent, and the liquid sample enters the sampling head 400 and the sampling tube 200.

In the working process of the swab 10 for cell sampling, the handle 100 is held by hand to send the sampling head 400 to the part to be detected, the handle 100 rotates the sampling head 400, the sampling head 400 drives the scraper 410 to rotate to collect the cells of the part to be detected, and the cells of the part to be detected enter the sampling groove 402 of the scraper 410. On the other hand, in the process of rotating the sampling head 400, the pressing plate 330 is gently and slowly pushed, so that the pressing plate 330 drives the piston 340 to slide in the sampling tube 200 through the connecting rod 320 and the sliding rod 310, thereby forming a suction force. The liquid sample of the site to be detected is sucked into the sampling head 400 and the sampling tube 200 through the sampling holes 401 provided in the sampling head 400. The swab 10 for sampling cells has high efficiency of collecting liquid samples, can collect more liquid samples at one time, and avoids the dropping and loss of the collected samples from the sampling head 400. In addition, the swab 10 for sampling cells can collect cells at a site to be detected while collecting a liquid sample during rotation.

In order to increase the working stability of the swab 10 for cell sampling, in one embodiment, the anti-slip pattern is disposed on the surface of the pressing plate 330 facing away from the connecting rod 320 to increase the friction between the pressing plate 330 and the finger. In this embodiment, a non-slip pad is disposed on a surface of the pressing plate 330 facing away from the connecting rod 320. Further, the non-slip mat is soft rubber pad, and soft rubber pad has certain elasticity, good toughness and good wear resistance, and soft rubber pad has increased the frictional force between pressing board 330 and the finger when the protection is pressed board 330 and finger to the job stabilization nature of the swab 10 that is used for the cell sample has been increased. In another embodiment, the non-slip pad is a soft silicone pad. In yet another embodiment, anti-slip lines are provided on the anti-slip pad to further increase the friction between the pressing plate 330 and the finger. Thus, the non-slip pad provided on the side of the pressing plate 330 facing away from the connecting rod 320 increases the frictional force between the pressing plate 330 and the finger, thereby increasing the working stability of the swab 10 for cell sampling.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
