Description

Technical Field

[0001] The present invention relates to the technical field of nucleic acid detection, and in particular to a combined nucleic acid sampling booth. Background Art

[0002] The purpose of nucleic acid testing is to screen those who are at risk of infection, so that each of us can be more assured and safer. And doing nucleic acid is also for your own safety. The substance of nucleic acid testing is the nucleic acid of the virus. Nucleic acid testing is to find out whether there is nucleic acid of foreign invading viruses in the patient's respiratory specimens, blood or feces to determine whether the patient is infected with the new coronavirus. Therefore, once the nucleic acid test is "positive", it can be proved that the virus exists in the patient's body, so doing nucleic acid is a good way to detect whether we are infected with the new coronavirus.

[0040] Working principle: when not working, the nucleic acid bottle 8 is placed in the nucleic acid placement rack 10, and the nucleic acid bottle cap 9 is placed on the inclined slide 506; when the medical staff starts to do nucleic acid, the cotton swab collected from the sample is placed on the nucleic acid bottle 8, and the nucleic acid bottle 8 is pressed downward, and the nucleic acid bottle 8 drives the lower pressing block 304 to move downward, and the lower pressing block 304 drives the first connecting plate 303 to move downward, and the upper pressing block 301 moves forward under the elastic force of the first spring 302 to break the cotton swab. After the cotton swab is broken, the lower pressing block 304 is reset under the action of the second spring 305, and then drives the upper pressing block 301 to reset, and repeats this; at the same time, when the lower pressing block 304 moves downward, it drives the first limit plate 303 to move downward. The positioning block 405 moves downward, thereby driving the forward plate 401 to move forward. When the forward plate 401 moves forward, the first touch plate 412 contacts the travel switch 410, so that the driving member 403 drives the first rotating rod 402 to rotate, thereby driving the displacement plate 404 to move forward until the second touch plate 412 is just not in contact with the travel switch 410. At this time, the nucleic acid placement rack 10 drives the first nucleic acid bottle 8 to move forward until the second nucleic acid bottle 8 is just located below the upper pressing block 301. When the first touch plate 412 moves forward, it drives the top plate 413 to move and then drives the push rod 406 to move forward. When the eight nucleic acid bottles 8 are used up, at this time , the front end of the forward piece 401 just contacts the manual cylinder valve 407, the manual cylinder valve 407 is started and then drives the cylinder push rod 408 and the cylinder 409 to start, so that the forward piece 401 is reset to the first end of the push rod 406 just contacts the manual cylinder valve 407; when the nucleic acid placement rack 10 drives the nucleic acid bottle 8 to move forward, the nucleic acid bottle 8 contacts the nucleic acid bottle cap 9, because the nucleic acid bottle 8 is always moving forward, the nucleic acid bottle cap 9 drives the bottle cap positioning plate 504 to rotate after contacting the nucleic acid bottle 8, and the nucleic acid bottle cap 9 falls downward to the opening of the nucleic acid bottle 8, and is tightened on the nucleic acid bottle 8 under the friction force of the two fixing plates 203 of the tightening mechanism. At this time, the third spring Under the action of 503, the bottle cap positioning plate 504 is reset to clamp another nucleic acid bottle cap 9, and this is repeated; when the nucleic acid bottle caps 9 are all tightened on the nucleic acid bottles 8, the nucleic acid placement rack 10 continues to move forward, and under the action of gravity, one end of the nucleic acid placement rack 10 falls on the nucleic acid collection plate 601. When the nucleic acid placement rack 10 completely falls on the nucleic acid collection plate 601, it pushes the second limit block 602 to move and then drives the fourth spring 604 to move toward the third fixing plate 606, and the oblique mouth of the nucleic acid collection plate 601 moves forward. When the second nucleic acid placement rack 10 arrives, the oblique mouth of the nucleic acid collection plate 601 is just used to collect the second nucleic acid placement rack 10;When the four oblique openings on the nucleic acid collection tray 601 have collected all the nucleic acid placement racks 10, the nucleic acid collection tray 601 moves toward the conveying table 701 under the action of gravity, and the roller 702 rotates to drive the nucleic acid collection tray 601 to move forward. When the bottom end of the nucleic acid collection tray 601 contacts the first spring block 703 and presses it downward, the first spring block 703 drives the pressing rod 705 to move downward and drives the limiting rod 706 to move downward. The limiting rod 706 drives the third limiting block 707 to rotate and then drops the nucleic acid collection tray 601 thereon onto the collection tray support table 605. Subsequently, under the action of the fifth spring 704, the first spring block 703 is reset and drives the third limiting block 707 to reset, and this is repeated. ;
