[0002] With the acceleration of globalization, the flow of people has become increasingly frequent, which not only promotes economic and cultural exchanges, but also makes the spread of infectious diseases more frequent and complex. Especially in the prevention and control of respiratory infectious diseases, such as influenza virus, large-scale and efficient throat swab sampling activities have become one of the key measures for epidemic prevention and control.

[0003] Traditional throat swab sampling mainly relies on medical staff to operate. This process not only consumes a lot of human resources, but also has many risks and challenges.

[0043] The frame 1, the packaging and extrusion bag module 2 and the packaging and throat swab stacking module 3 are all built with Lego components.

[0044] Working principle of this embodiment:

[0045] The packaging extrusion bag module 2 includes a left extrusion roller 13 and a right extrusion roller 16 arranged horizontally on the left and right sides, and the two are driven to rotate by the first drive motor 8 and the second drive motor 15 respectively. A left linkage gear roller 14 is rotatably installed directly below the left extrusion roller 13, and a right linkage gear roller 17 is rotatably installed directly below the right extrusion roller 16. The left linkage gear roller 14 and the right linkage gear roller 17 rotate in the opposite direction and at the same linear speed as the left extrusion roller 13 and the right extrusion roller 16, respectively, to achieve the clamping and pushing of the throat swab packaging bag. The left linkage gear roller 14 includes a pair of gears 18 arranged front and back, and a throat swab avoidance groove 19 is left between the gears 18 for avoiding the throat swab. The right linkage gear roller 17 also includes a pair of gears 18 arranged front and back, but a throat swab pressing roller 20 is provided between the gears 18 for pressing the throat swab rod. When a human hand approaches the ultrasonic hand recognition sensor 4, a signal is transmitted to the control 7, and the controller 7 starts the program and starts working. The complete pharyngeal swab packaging bag is moved from the pharyngeal swab stacking module 3 to the packaging extrusion bag module 2 via the conveyor belt 21. The first drive motor 8 and the second drive motor 15 rotate forward to drive the pharyngeal swab packaging to continue to move to the left. When the head of the pharyngeal swab extends out of the left extrusion roller 13, the right color recognition sensor 6 recognizes that the tail of the pharyngeal swab packaging bag has just passed completely. At this time, the right linkage gear roller 17 and the right extrusion roller 16 just clamp the rod of the pharyngeal swab. At this time, the first drive motor 8 and the second drive motor 15 stop rotating; then the first drive motor 8 rotates in the opposite direction. Due to the existence of the pharyngeal swab avoidance groove 19, the left extrusion roller 13 and the left linkage gear roller 14 only clamp the position of the head of the pharyngeal swab packaging bag, and do not press the pharyngeal swab contained inside. The reverse rotation process causes the head of the packaging bag to move to the right, and the pharyngeal swab head is automatically ejected from the head of the packaging bag. Then, when the ultrasonic hand recognition sensor 4 recognizes that the hand has left, it means that the throat swab has been taken away. At this time, the first drive motor 8 and the second drive motor 15 need to rotate forward to drive the packaging bag retained in the packaging extrusion bag module 2 to be discharged from the left side.

[0046] The specific working steps of the packaging extrusion bag module 2 are as follows.

[0047] Start and convey: When a person's hand approaches the ultrasonic hand recognition sensor, the controller starts the program and the conveyor belt moves the throat swab packaging bag to the packaging extrusion bag module.

[0048] Clamping and moving: The first drive motor and the second drive motor rotate forward, driving the left squeezing roller, the right squeezing roller and the corresponding linked gear roller to clamp the packaging bag and continue to move to the left.

[0049] Identification and clamping: When the head of the throat swab extends out of the left squeezing roller, the right color recognition sensor recognizes that the tail of the packaging bag has completely passed through. At this time, the right linkage gear roller and the right squeezing roller clamp the rod of the throat swab.

[0050] Reverse rotation and ejection: After the motor stops rotating, the first drive motor rotates in the reverse direction. Due to the presence of the throat swab avoidance groove, the left squeezing roller and the left linkage gear roller only clamp the head of the packaging bag, but do not press the throat swab. Reverse rotation causes the head of the packaging bag to move to the right, and the head of the throat swab is automatically ejected from the head of the packaging bag.

[0051] Hand leaving and discharge: When the ultrasonic hand recognition sensor detects that the hand has left, it means that the throat swab has been taken away. At this time, the first drive motor and the second drive motor rotate forward, driving the packaging bag trapped inside the module to be discharged from the left side. After the left color recognition sensor recognizes that the packaging bag has been discharged, the device stops working.

[0052] In this embodiment, the packaging extrusion bag module controls the rotation direction and speed of the motor through a program, and uses the linkage gear roller and the avoidance groove to achieve effective clamping, movement and release of the throat swab packaging bag. At the same time, through the cooperation of sensors and controllers, automated operation and intelligent control are achieved.

[0053] The first drive motor 8 and the second drive motor 15 adopt the driven large gear 9 and the driving small gear 10 to cooperate and drive, which can improve the working efficiency. The front ends of the rotating shafts of the left squeezing roller 13 and the right squeezing roller 16 are fixedly installed with upper gears 11 of the same diameter as them, and the front ends of the rotating shafts of the left linkage gear roller 14 and the right linkage gear roller 17 are fixedly installed with lower gears 12 of the same diameter as them. The upper gear 11 is meshed and installed with the lower gear 12, so that the left squeezing roller 13 and the left linkage gear roller 14, and the right squeezing roller 16 and the right linkage gear roller 17 can rotate synchronously in the opposite direction.

[0054] The packaged throat swab stacking module 3 includes a throat swab stacking groove 24 for placing throat swabs and packaging bags. A throat swab bag push roller 25 is provided at the bottom of the throat swab stacking groove 24, which is driven to rotate by a third drive motor 26 fixedly mounted on the outside of the frame 1, and is used to push the packaging bag and throat swab forward. The conveyor belt 21 is an unpowered conveyor belt, and a push roller 22 is installed on the top. The push roller 22 rotates synchronously with the throat swab bag push roller 25 through a belt drive, and is used to move the packaging bag from the stacking position to the packaging extrusion bag module 2. A small bevel gear 27 is fixedly mounted on the output shaft of the third drive motor 26, and the small bevel gear 27 is meshed and installed with a large bevel gear 28 actively mounted on the outside of the frame 1, and the large spur gear 30 is meshed and installed with the small spur gear 29 to amplify the rotation speed, thereby realizing the reversing transmission of power and improving the material movement efficiency.

[0055] A rotating arm 36 is rotatably mounted on the top of the right end of the throat swab stacking slot 24, and a bag pressing plate 31 is hinged at the end of the rotating arm 36. A hinge device 32 is provided in the bag pressing plate 31, including a ball seat 35 fixedly connected to the bag pressing plate 31, a ball head 34 is movably mounted in the ball seat 35, and a connecting rod 33 at the end of the ball head 34 is fixedly connected to the rotating arm 36, so as to realize the flexible rotation of the bag pressing plate 31. The above structure enables the bag pressing plate 31 to keep applying force from the top to press the throat swab packaging bag, ensuring that it is placed accurately.

[0056] The device can also expand the automatic hand sanitizer extrusion module on both sides of the rack 1 to facilitate personnel to disinfect their hands before and after sampling. At the same time, it can cooperate with the throat swab cutting end module to realize the automatic cutting and collection of the throat swab, further improving the sampling efficiency.

[0057] The rack 1, the packaging extrusion bag module 2 and the packaging throat swab stacking module 3 are all built with LEGO components, adopting a modular and reconfigurable design method, and have the advantages of easy construction, maintenance and scalability.
