Description

Technical Field

[0001] The present invention relates to the technical field of virus sample collection, and more specifically, to a virus sample collection device. Background Art

[0002] A virus is a very tiny, simple life form that can be transmitted through air, water, food, contact, etc., infecting animals, plants and humans, and causing disease. When collecting virus samples from people, animals or plants infected with the virus, a swab is usually used as a collection tool to collect the virus sample, and then the virus sample is placed in a collection bottle so that the front end of the swab is preserved in the virus nucleic acid preservation solution inside the collection bottle.

[0003] After the virus sample is collected using a swab, the swab needs to be placed in a sampling tube in which a certain amount of virus nucleic acid preservation solution is pre-stored. However, after the staff opens the sampling tube, the internal virus nucleic acid preservation solution may leak due to operational errors. In addition, since the collection tube and the tube cover are connected by threads, when the tube cover is used for sealing, the angle between the tube cover and the collection tube may be skewed, resulting in a certain gap at the top of the collection tube, further causing the virus nucleic acid preservation solution to leak. This is particularly prominent when a single person is sampling. After the virus nucleic acid preservation solution leaks, a new sampling tube needs to be replaced or even a new swab needs to be used for re-sampling, resulting in a waste of collection tube and virus nucleic acid preservation solution resources and a decrease in collection efficiency.

[0043] See also Figures 6 to 8 The top of the groove drum 33 is fixedly connected with a gasket 322, which is made of rubber material. When the rubber gasket 322 at the bottom of the groove drum 33 is pressed by hand, the friction between the hand and the top of the groove drum 33 can be increased, and the hand is not easy to slip when pressing the groove drum 33;

[0044] See also Figure 8 , Fig. 9 and Fig.12 A positioning ring 323 is fixedly connected to one side of the pipe cover 5.

The upper and lower sides of the inner wall of the spiral groove 34 are fixedly connected with metal edges 325, and the edge of the metal edges 325 is arc-shaped. By arranging the arc-shaped metal edges 325 on the inner wall of the spiral groove 34, it is easier for the protrusion 36 to rotate inside the spiral groove 34 without being stuck with the groove barrel 33.

[0045] Method of use: When the present application is in use, the tube cover 5 is pulled out. When the tube cover 5 is pulled out, the insertion rod 28 will slide upward on the inner wall of the slot 27. When the insertion rod 28 moves upward, one end of the slot block 212 will contact one end of the inner wall of the rectangular slot 29, pushing the slot block 212 to rotate toward the inside of the rectangular slot 29 through the second rotating shaft 210 and causing the coil spring 211 to deform, so that the slot block 212 fits the inner wall of the rectangular slot 29 as much as possible, and one end of the slot block 212 will not contact the outer surface of the L-shaped rod 24. The tube cover 5 is pulled out until the insertion rod 28 is about to be separated from the inside of the slot 27, and the swab 6 inside the collection tube 1 is taken out. The virus sample is collected through the cotton ball at the front end of the swab 6. After the collection is completed, the cotton ball end of the swab 6 is inserted downward into the collection tube 1. The pipe cover 5 is pressed down to make the insertion rod 28 slide downward on the inner wall of the slot 27. During the entire sliding process of the insertion rod 28, the slot block 212 is located inside the rectangular slot 29. When the bottom end of the insertion rod 28 is located at the infusion slot 26, the coil springs 211 at both ends of the second rotating shaft 210 will gradually return to their original state and drive the second rotating shaft 210 to rotate so that the slot block 212 rotates in a direction away from the rectangular slot 29. At this time, the insertion rod 28 continues to slide down and one end of the slot block 212 will be placed on the top end of the L-shaped rod 24. At the same time, the top end of the slot block 212 will contact one side of the top end of the inner wall of the rectangular slot 29, so that the slot block 212 is stuck between the insertion rod 28 and the L-shaped rod 24. When the insertion rod 28 continues to move downward so that the bottom end contacts the bottom end of the inner wall of the infusion slot 26, the slot block 212 will press down the L-shaped rod 24. The L-shaped rod 24 is rotated toward the film 22 through the first rotating shaft 23, and the film 22 is scraped open by the end of the L-shaped rod 24 away from the first rotating shaft 23, so that the virus nucleic acid preservation liquid located on one side of the baffle 21 and the film 22 in the liquid-filling tube 4 flows out and enters the cotton ball end of the swab 6 wrapped at the bottom of the collection tube 1 through the infusion groove 26. When the groove block 212 is stuck between the insertion rod 28 and the L-shaped rod 24, the insertion rod 28 is moved to slide downward on the inner wall of the slot 27, which makes the rotating rod 213 at the top of the groove block 212 rotate at the top of the groove block 212, pushing the sliding rod 215 to slide upward for a distance on the inner wall of the circular groove 214, so that the top of the sliding rod 215 squeezes the first air bag 216 to squeeze the air inside the first air bag 216 to the annular groove 217. The airbag sheet 218 is expanded to fill the contact point between the top of the inner wall of the tube cover 5 and the top of the collection tube 1, and the contact point between the top of the tube cover 5 and the top of the collection tube 1 is further sealed. Then, the grooved cylinder 33 is pressed downward to control the round rod 32 to slide downward on the inner wall of the straight cylinder 31. When the grooved cylinder 33 moves downward on the outer surface of the cylinder 35, the protrusion 36 on the top side of the cylinder 35 will slide inside the spiral groove 34 on the outer surface of the grooved cylinder 33, and the cylinder 35 follows the movement of the protrusion 36 inside the spiral groove 34 to rotate in the clockwise direction, and the second gear 311, the shaft rod 310 and the third gear 312 are driven to rotate in the counterclockwise direction through the first gear 39, and the gear ring 313 is pushed to rotate in the clockwise direction on the outer surface of the tube cover 5 through the third gear 312.The end of the snap ring 315 on one side of the gear ring 313 is made to contact with the top of the conical block 319 inside the groove 318 at one end of the arc rod 316 on the outer surface of the collection tube 1. The gear ring 313 continues to rotate to push the conical block 319 to rotate into the groove 318, so that the snap ring 315 enters the outer surface of the arc rod 316 and is sleeved on the outside of the arc rod 316. When the groove drum 33 cannot move downward any further, the snap ring 315 is completely sleeved on the outside of the arc rod 316. The conical block 319 is manually pushed upward so that the conical block 319 is located on one side of the snap ring 315. The position of the snap ring 315 on the outer surface of the arc rod 316 is limited by the stop block 317 and the conical block 319. The conical block 319 is prevented from rotating outward by the rectangular sheet 320, so that the relative position between the tube cover 5 and the collection tube 1 is tightened, and the groove drum 33 is in the cylinder When the outer surface of the cylinder 35 moves downward, the internal pressure rod 38 will compress the second airbag 37 inside the cylinder 35, and the air inside the second airbag 37 will be input into the first airbag 216 and enter the airbag sheet 218 through the first airbag 216, further expanding the airbag sheet 218, and sealing the contact between the top of the inner wall of the tube cover 5 and the top of the collection tube 1. When the swab 6 inside the collection tube 1 needs to be taken out, the top of the conical block 319 is pressed by hand to push the conical block 319 outward to break the auxiliary groove 321 where the conical block 319 and the outer surface of the rectangular sheet 320 are connected, and then the clamping ring 315 is pushed on the outer surface of the arc rod 316 to move in the direction of the third gear 312 so that the clamping ring 315 is separated from the outer surface of the arc rod 316 to release the position fixation of the tube cover 5 and the collection tube 1, and then the tube cover 5 is pulled out to take out the swab 6.
