Description

Technical Field

[0001] The present invention belongs to the field of pathogen sampling and testing, and in particular relates to an expandable oropharyngeal swab sampling workstation. Background Art

[0002] The 2002 Severe Acute Respiratory Syndrome (SARS), the 2019 COVID-19, and the 2023 influenza A outbreak have posed significant challenges to my country's public health and the prevention and control of large-scale infectious diseases. Throughout the lifecycle of a public health event, effective control of viral transmission requires the collection of multiple pathogen markers, including viral nucleic acids and surface receptor proteins, through oropharyngeal swabs, which are then sent to specialized testing institutions for analysis.

[0003] Typically, oropharyngeal swab sampling is performed by trained samplers with nursing or medical qualifications. During this process, the samplers are at risk of exposure and infection, and it is difficult to ensure the accuracy of the sampling site due to long working hours, which highlights the importance of automated oropharyngeal swab sampling devices.

[0004] The Chinese invention patent application with application number CN202011131670.9 and titled "A High-efficiency and Automated Intelligent Collection System for Coronavirus Nucleic Acid" discloses a design scheme for a high-efficiency and automated intelligent collection system for coronavirus nucleic acid. The design scheme is equipped with a facial bracket and an identity recognition device on the front side of the workbench. The main body of the nucleic acid sampling is a six-axis robot. The sampling test tube placement tooling is respectively provided with an untested area, a tested area and a tested area. At the same time, there is also a matching screw-cap grabbing mechanism for opening and closing the test tube cap.

[0005] Although this intelligent collection system has realized automated nucleic acid sampling and avoided the exposure and infection risks brought by manual sampling, its shortcomings are as follows: (1) The six-axis robotic arm for oropharyngeal swab sampling has redundant degrees of freedom of movement. Excessive degrees of freedom will increase the difficulty of control and increase costs, and the movement of the six-axis robotic arm will increase the sampling time; (2) There is no explanation on how to embed the swab into the robotic arm. If the examinee inserts the swab into the robotic arm on his own, the contact between the examinee and the swab will cause the risk of inaccurate detection; (3) The scalability of the sampling system in the case of large-scale oropharyngeal swab sampling is not considered; (4) It is limited to the collection of new coronavirus nucleic acid. The nucleic acid sampling booth with a single six-axis robot as the main body has low working efficiency and is likely to cause queue congestion for examinees, thereby increasing the risk of cross infection. Summary of the Invention

[0006] In order to solve the above-mentioned problems existing in the prior art, the present invention provides an expandable oropharyngeal swab sampling workstation with high sampling efficiency, so as to solve the technical problems that the existing novel coronavirus nucleic acid intelligent collection system has low working efficiency, which easily causes queues of examinees to be congested and increases the risk of cross-infection.

[0138] Before the expandable oropharyngeal swab sampling workstation is put into operation, the staff uses a cable to connect the expandable oropharyngeal swab sampling workstation to an external power source to ensure that all power equipment inside the expandable oropharyngeal swab sampling workstation operates normally;

[0139] Subsequently, the various systems in the workstation 1 are turned on, the disinfection spray head and the air supply device start working, the moving parts are reset, and the sampling window 16 is opened; then, the staff can enter the operating room 131 to prepare for sampling (prepare test tubes and swabs) and close the outward door at the same time.

[0140] During operation of the expandable oropharyngeal swab sampling workstation, the staff places the test tube rack containing the test tubes into the test tube delivery space through the test tube delivery window and closes the test tube inter-transfer partition. At this time, the test tube inter-transfer partition 1322 is also in a closed state, and the disinfection device 1331 sprays disinfectant into the test tube delivery space to disinfect the test tubes and the test tube rack.

[0141] After the test tubes and test tube racks are fully disinfected, the movable partition 1322 between the test tubes is opened, and the test tube transfer system 32 sequentially transfers one of the test tubes on the test tube rack to the center position of the test tube fixture 342. When the infrared or photoelectric sensor on the test tube fixture 342 detects that the test tube has reached the correct position, the connecting rod 3422 in the test tube fixture 342 will clamp the test tube under the drive of the servo 3424 and the crank slider mechanism 3423.

[0142] Next, the test tube cover opening and closing robot arm 341 starts working to remove the test tube cover. At this time, the swab conveyor 311 holding the swab placed by the staff arrives at the sampling robot arm 221 where the pathogen marker sampling needs to be completed and stops. The clamping head 2214 in the sampling robot arm 221 will grab the swab on the swab conveyor 311; and when the clamping head 2214 in the sampling robot arm 221 clamps the swab, the central processing unit will transmit an instruction to the swab clamping device on the swab conveyor 311 to release the swab. Then the sampling robot arm 221 rotates a certain angle to the vicinity of the mandibular support frame 222 to prepare for the sampling of pathogen markers. The swab conveyor 311 will return to the operating room 131 from the sampling area 132 along the conveying track 312.

[0144] After the sampling is completed, the rotating boss 2211 rotates 180 degrees, and the sampling head of the swab on the sampling robotic arm 221 falls into the test tube of the test tube fixing device 342 under the action of the swab cutting system 33. Then, the sampling robotic arm 221 rotates a certain angle so that the sampling robotic arm 221 is located above the medical waste holding unit 23, and then the swab rod is released. The swab rod falls into the medical waste holding unit 23 by gravity, and the sampling robotic arm 221 prepares for the next round of pathogen marker sampling.

[0145] When the test tube on the test tube fixture 342 is filled with the specified number of samples, the test tube cover opening and closing robot arm 341 will re-close the clamped cover on the test tube. Then, the test tube transport system 32 will clamp the test tube on the test tube fixture 342. The central processing unit will issue a command to the test tube fixture 342 to release the test tube. The test tube will be transported by the test tube transport system 32 and placed on the test tube rack in the test tube delivery space.

[0146] After all the test tubes on the test tube rack have been sampled, the movable partition driving device 1323 will drive the movable partition 1322 between the test tubes to move, so that the test tube delivery space is isolated from the sampling area 132, and the disinfection device 1331 starts to disinfect the test tubes and test tube racks in the test tube delivery space again. After sufficient disinfection, the translation partition between the test tubes will be opened by the translation partition driving device, and the staff can replace the test tube rack and test tubes. This cycle is repeated to quickly complete the sampling of pathogen markers.

[0147] This scalable oropharyngeal swab sampling workstation can not only efficiently, accurately, and safely collect viral nucleic acid antigens, antibodies, and receptor proteins, but can also collect markers for other pathogens (such as bacteria and fungi) from other parts of the human body. Furthermore, it can be rapidly deployed in communities for public health incident prevention and control, and can also be deployed in hospital laboratories to efficiently collect patient body fluids.
