[0023] Reference Figure 1-3 The figure shows a preferred embodiment of the present invention.

[0024] The split throat swab self-service sampling device provided in this embodiment uses a throat swab 702 to sample the liquid in the user's throat, and then tests the sampled liquid to determine whether the user has nucleic acid from foreign invading viruses to determine whether the user is infected with the new coronavirus or other viruses, not just the new coronavirus.

[0025] The split throat swab self-service sampling equipment includes a pre-processing chamber, a sampling unit and a post-processing chamber. The pre-processing chamber, the sampling unit and the post-processing chamber are arranged separately and at intervals. That is to say, along the sampling process, the pre-processing chamber, the sampling unit and the post-processing chamber are arranged in sequence and at intervals.

[0026] An assembly structure for assembling the sampling tool 300 is provided in the pre-processing chamber, and the assembled sampling tool 300 has a pharyngeal swab 702; the sampling unit has a display screen, and the display screen guides the user to hold the sampling tool 300 and use the pharyngeal swab 702 to perform pharyngeal sampling. When the user gets the sampling tool 300 and comes to the sampling unit, the display screen will gradually guide the user to perform sampling through video and voice, and the entire process is monitored by video. When the user makes mistakes in sampling, the video and voice on the display screen will synchronously remind the user.

[0027] The post-processing chamber is provided with a screwing structure for twisting off or closing the tube cover of the sampling tube 400, a cutting structure for cutting the throat swab 702 collected by the sampling tool 300 and placing it in the sampling tube 400, and a storage robot for placing the sampling tube 400 containing the throat swab 702 in the sample storage box 203.

[0028] When the cut throat swab 702 needs to be placed in the sampling tube 400 , the cap screwing structure will twist open the tube cap of the sampling tube 400 in advance. When the throat swab 702 is placed in the sampling tube 400 , the cap screwing structure will cover the tube cap on the sampling tube 400 .

[0029] In the split throat swab self-service sampling equipment provided above, the sampling tool 300 is assembled in the pre-processing chamber through the assembly structure. The user obtains the sampling tool 300 in the pre-processing chamber, and performs sampling operations in the sampling unit according to the video and voice on the display screen. The sampling tool 300 after sampling is placed in the post-processing chamber, and the tube cover of the sampling tube 400 is unscrewed through the cap screwing structure, and the throat swab 702 is cut off through the shearing structure and placed in the sampling tube 400, and then the tube cover is covered on the sampling tube 400, and the sampling tube 400 is placed in the sample storage box 203 by the storage robot to complete the entire sampling operation. The entire process does not require cross-contact between staff and users, which greatly reduces the probability of staff being infected with the virus and avoids safety hazards. In addition, the efficiency of the entire sampling operation is high, which can meet the rapid nucleic acid sampling needs of a large group of users.

[0030] In this embodiment, a sensing area, a user camera and a scanning head are provided on the pre-processing chamber. The sensing area samples the user's ID card information, the user camera samples the user's head portrait information, and the scanning head scans the barcode on the sampling tool 300 obtained by the user.

[0031] In this way, by using the dual authentication of the sensing area and the user's camera, the user's information can be further determined to ensure the accuracy of the user information sampling, and the user's information corresponds one-to-one with the information of the sampling tool 300.

[0032] The sampling tool 300 is provided with a sampling camera 704. When the throat swab 702 of the sampling tool 300 is sampling, the sampling tool 300 communicates wirelessly with the host system. The sampling tool 300 is provided with an RFID card. The sampling tool 300 communicates wirelessly with the host system by using the RFID card. The sampling camera 704 records the sampling and transmits the sampling video to the host system. The host system determines whether the sampling operation is qualified.

[0033] The sampling tool 300 includes a handheld handle 701 and a protective cover 301. The throat swab 702 is inserted into the front end of the handheld handle 701. The throat swab 702 has a sampling end exposed in front of the sampling tool 300. When the user takes a sample, the user bites the mouth opener 705 in his or her mouth, and the sampling end of the throat swab 702 passes through the mouth opener 705 and directly abuts the sampling position of the user's throat.

[0034] The mouth opener 705 has two through holes for the throat swab 702 to pass through, so that after the throat swab 702 passes through the through holes, the spacing distance and position of the throat swab 702 can be accurately located. The outer end of the mouth opener 705 has a positioning cavity, and the front end of the sampling tool 300 is directly embedded in the positioning cavity, so that the sampling tool 300 can be accurately located.

[0035] The sampling camera 704 is set at the front end of the sampling tool 300. When the user holds the sampling tool 300 for sampling, the sampling camera 704 can record the entire sampling process in real time, and transmit the sampling video or sampling image to the host system in real time. The host system analyzes the sampling video or sampling image, and then determines whether the user's sampling operation is correct. If correct, continue to the next step. If the sampling is wrong or the sampling is wrong, the user needs to re-sample.

[0036] The pre-treatment chamber is provided with a peeling structure for peeling the throat swab 702 from the throat swab roll, an inserting structure for inserting the throat swab 702 on the handheld handle 701, and a push cover structure for covering the protective cover 301 on the handheld handle 701.

[0037] In this way, the throat swab 702 in the throat swab roll can be directly peeled out through the peeling structure, and then the protective cover 301 is covered on the handheld handle 701 through the push cover structure. The protective cover 301 seals the throat swab 702 on the handheld handle 701 to play a protective role.

[0038] The stripping structure includes an active roller 102 for driving the throat swab roll to rotate, and two stripping rollers 104 are arranged in parallel and spaced apart below the active roller 102 for stripping the two side packaging surfaces of the throat swab roll apart. There is a gap between the two glass rollers for the throat swab roll to pass through, so that the throat swab roll passes through the gap between the two stripping rollers 104, and the two stripping rollers 104 respectively roll up the packaging surfaces on both sides of the throat swab roll to strip apart, so that the throat swab 702 between the packaging surfaces on both sides falls downward.

[0039] In this embodiment, auxiliary rollers 103 are respectively arranged on both sides of the active roller 102, and the peeled packaging surfaces are respectively rolled up on the auxiliary rollers 103. A transition roller is arranged between the active roller 102 and the auxiliary roller 103, and the transition roller is located above the peeling roller. In this way, the packaging surface passes through the transition roller and is then rolled up on the auxiliary roller 103.

[0040] The insertion structure includes a receiving groove arranged below the gap and accommodating the fallen throat swab 702. The fallen throat swab 702 is placed in the receiving groove. The receiving groove is provided with a clamping and pushing claw for clamping the throat swab 702 and inserting it on the handheld handle 701, and a guide claw for allowing the throat swab 702 to pass through and guiding the throat swab 702.

[0041] The clamping and pushing claws clamp the pharyngeal swab 702 in the receiving groove. During the pushing process, the pharyngeal swab 702 passes through the guiding claws. The guiding claws can guide the pharyngeal swab 702 axially, so that the pharyngeal swab 702 can be accurately inserted into the handheld handle 701.

[0042] The pre-processing chamber is provided with a gripping manipulator 101 for grabbing the hand-held handle 701 to the flipping station 105 .

[0043] In the pre-processing chamber, the handle 701 is initially arranged vertically. The gripping manipulator 101 grabs the handle 701 and places it vertically on the flipping station 105. The flipping station 105 rotates 90 degrees to flip the handle 701 to a horizontal state.

[0044] The cover pushing structure includes a cover conveying groove 107 for transmitting the protective cover 301 to move and a rotating disk 106. The rotating disk 106 is arranged at the end of the cover conveying groove 107. The protective cover 301 is conveyed along the cover conveying groove 107. When the protective cover 301 enters the rotating disk 106, the rotating disk 106 rotates to align the protective cover 301 with the handheld handle 701 with the throat swab 702 inserted therein; a cover pushing head is arranged on the rotating disk 106, and the cover pushing head pushes the protective cover 301 to cover the handheld handle 701. In this way, the assembly of the entire sampling tool 300 is completed.

[0045] The cap screwing structure includes a tube clamping station 202 for placing the sampling tube 400 and a vertical axis located above the tube clamping station 202. After the sampling tube 400 is clamped and placed on the tube clamping station 202, the vertical axis descends, and a rotating head is provided at the bottom of the vertical axis. The rotating head has a clamping groove for clamping the tube cover and rotating it to detach the tube cover from the sampling tube 400 or to cover the tube cover on the sampling tube 400.

[0046] When the sampling end of the cut throat swab 702 needs to be placed in the sampling tube 400, the rotating head of the vertical axis unscrews the tube cover of the sampling tube 400. When the sampling end of the throat swab 702 is placed in the sampling tube 400, the rotating head of the vertical axis covers the tube cover of the sampling tube 400. Then, the storage robot places the sampling tube 400 with the throat swab 702 in the sample storage box 203.

[0047] The shearing structure includes a shearing clamp 201 which is arranged above the tube clamping station 202 and located outside the tube clamping station 202. When the tube cover on the sampling tube 400 is unscrewed, the shearing clamp 201 cuts off the throat swab 702 on the sampling tool 300 located above the tube clamping station 202, so that the sampling end of the throat swab 702 falls into the sampling tube 400.

[0048] A storage robot and a capping station are provided on the post-processing warehouse. The capping station is provided with a cap clamping claw 204. A cap dropping hole is provided below the cap clamping claw 204. A protective cover warehouse for placing the protective cover 301 is provided below the cap dropping hole. The storage robot clamps the sampling tool 300 with the throat swab 702 arranged downward after sampling to the capping station. The cap clamping claw 204 clamps the protective cover 301 on the sampling tool 300, and the protective cover 301 is separated from the handheld handle 701 and falls into the protective cover warehouse through the cap dropping hole.
