Description

Technical Field

[0001] The present invention relates to a sampling machine, in particular to a human-machine interactive device and method for collecting biological samples. Background Art

[0002] Throat swab sampling is an important method for detecting whether the sampler is infected with the virus. The process requires certain operating skills and reduces the risk of infection. Due to the different height characteristics of the sampled persons, the sampling machine cannot cater to the height of the sampled person's mouth; for example, taller people need to bend over or kneel, and shorter people need to stand on tiptoes or step on something. The sampled person needs to actively cooperate with the sampling height. Such a sampling process will be more troublesome, laborious, and very uncomfortable for the sampled person. At the same time, the sampling operation will result in some poor throat swab sampling results such as improper collection angle, force, and inaccurate collection area, thus affecting the accuracy of nucleic acid testing.

[0003] In addition, during the sampling process, when the sampler opens his mouth to take the sample, a large amount of droplets and aerosols will be sprayed out due to forceful breathing or uncontrollable coughing, which will cause air pollution in the surrounding environment and contaminate surrounding objects, posing a high risk of cross-infection.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 and Figures 3 to 6 As shown, this embodiment includes a sampling chamber 9, a lifting mechanism, a negative pressure generating device, an atomizing device, a sampling oral positioning device, a position recognition device and a visual recognition and feedback device, wherein a window 30 is opened on the front screen 26 of the sampling chamber 9, and the lifting mechanism, the atomizing device and the sampling oral positioning device are respectively arranged on the inner side of the window 30.

[0033] The lifting mechanism of this embodiment includes a lifting power source, a transmission mechanism, and a traction member 8. The lifting power source is mounted on the front screen 26. The lifting power source is connected to the traction member 8 via the transmission mechanism, driving the traction member 8 to move up and down. The window 30 of this embodiment is square. The front screen 26 on both sides of the window 30 is fixed with traction linings 6. The lifting power source of this embodiment includes a lifting drive motor 22 and a reducer 23. The lifting drive motor 22 and the reducer 23 are fixed to the traction linings 6 on both sides via a right-angle motor mount 24. The lifting drive motor 22 is connected to the input end of the reducer 23.

[0034] The transmission mechanism of this embodiment includes a synchronous belt mechanism, a traction central shaft 2 and a traction synchronous belt mechanism. The traction central shaft 2 is rotatably installed on the traction liners 6 on both sides. The output end of the lifting power source is connected to the traction central shaft 2 through a synchronous belt mechanism. Traction synchronous belt mechanisms are respectively provided on both sides of the traction member 8. Each side of the traction member 8 is connected to the traction central shaft 2 through the traction synchronous belt mechanism on the same side. The output end of the reducer 23 drives the traction central shaft 2 to rotate through the synchronous belt mechanism, and the traction central shaft 2 drives the traction member 8 to achieve lifting through the traction synchronous belt mechanism. The synchronous belt mechanism includes a synchronous pulley 3 and a synchronous belt 4. The synchronous pulley 3 is respectively installed on the output end of the reducer 23 and the traction central shaft 2, and the two synchronous pulleys 3 are connected by a synchronous belt 4; the traction synchronous belt mechanism includes a traction synchronous pulley 31, a traction synchronous belt 20 and a synchronous belt buckle 16. Traction synchronous pulleys 31 are provided at both ends of the traction central shaft 2 and both sides of the traction member 8. The two traction synchronous pulleys 31 arranged upper and lower on each side are connected by a traction synchronous belt 20, and each side of the traction member 8 is connected to the traction synchronous belt 20 on the same side through a synchronous belt buckle 16.

[0035] In this embodiment, both left and right sides of the traction member 8 are slidably connected to the traction lining 6 via traction rails 5. The traction rails 5 comprise an inner traction rail 501 and an outer traction rail 502. The inner traction rail 501 is fixed to the traction lining 6, while the outer traction rail 502 is fixed to the traction member 8. The outer traction rail 502 is slidably connected to the inner traction rail 501, ensuring that the traction member 8 moves only in the vertical direction, avoiding swinging and excessive vibration. A traction timing belt 20 provides power for the raising and lowering of the traction member 8, while the traction rails 5 constrain the traction member 8, ensuring that the traction member 8 and its attached components can only move along the traction rails 5. A proximity switch 17, mounted on the traction lining 6, is installed along the lifting track of the traction member 8 to limit the lifting position. In this embodiment, two proximity switches 17 are installed on each side of the traction member 8. The timing belt buckle 16 on each side moves with the traction timing belt 20 between the two upper and lower proximity switches 17 on the same side, preventing the traction member 8 from exceeding the specified position and damaging the machine.

[0036] The negative pressure generating device, atomizing device and sampling oral positioning device of this embodiment are respectively installed on the traction member 8. The sampling oral positioning device includes a bite 15 and a bite bracket 14. One end of the bite bracket 14 is installed on the traction member 8, and the other end is detachably connected to the bite 15. In order to position the mouth of the sampled person, the bite bracket 14 is arranged to extend outward toward the side of the sampled person, which is more in line with the human body structure, making the sampling process of the sampled person more comfortable and convenient. The end of the bite 15 close to the sampled person is provided with a tongue depressor 1502, and the other end away from the sampled person is provided with a groove 1501. The design of the bite 15 is more in line with the human oral structure. During the sampling process, the sampled person bites the bite 15 and places the upper teeth of the mouth into the groove 1501 for positioning. The tongue is under the tongue depressor 1502, which is convenient for sampling with a sampling swab.

[0037] The traction member 8 has a space for accommodating the head of the person being sampled. The mouthpiece support 14 and mouthpiece 15 are located within this space. Multiple suction holes 35 are provided on the traction member 8 outside this space. The traction member 8 is internally hollow, and each suction hole 35 is connected to the interior of the traction member 8. One end of a negative pressure generating device is connected to a negative pressure source, and the other end is connected to the suction holes 35 provided on the traction member 8. The sterilized atomized air is sucked away by the negative pressure generating device. The shape of the traction member 8 is not limited and can be U-shaped or a closed "mouth" shape. In this embodiment, the traction member 8 is U-shaped. The negative pressure generating device includes a negative pressure source and a pipeline 36. Multiple suction holes 35 are provided on the inner sides of the vertical edges of the U-shaped opening. The traction member 8 is connected to the negative pressure source via the pipeline 36. The sterilized atomized air has a stimulating effect on human breathing. The negative pressure generating device is used to suck the atomized disinfectant and possibly incompletely sterilized air through the suction holes 35 for a unified disinfection process.

[0038] Since the person being sampled will contaminate the mouthpiece 15, nearby instruments and nearby air by breathing during the sampling process, the atomizing device will atomize the disinfectant and spray it out to disinfect the nearby air and instruments, and the mouthpiece 15 will be replaced, thereby reducing the possibility of mutual infection between the people being sampled. The atomizing device of this embodiment includes a float valve 10, a centrifugal blower 11, an atomizing shell 12, an atomizing generator 13 and a spray chamber 19. The atomizing shell 12 is installed at the bottom of the traction member 8. The atomizing generator 13 is installed in the atomizing shell 12 and is filled with disinfectant. The atomizing generator 13 is immersed in the disinfectant and atomizes the disinfectant. The atomized disinfectant is stored in the atomizing shell 12; the centrifugal blower 11 is fixed to the outer surface of the atomizing shell 12 and is connected to the interior of the atomizing shell 12 through an air duct. The connection point between the pipe and the atomizing housing 12 is located above the liquid level of the disinfectant and below the lower end of the spray chamber 19. A hollow spray chamber 19 is mounted on the traction member 8. The upper end of the spray chamber 19 is U-shaped, corresponding to the traction member 8. Spray ports 25 are formed on the inner sides of the vertical sides of the U-shaped opening and at the bottom of the U-shape. The lower end of the spray chamber 19 is located within the atomizing housing 12. A centrifugal blower 11 passes the atomized disinfectant through the spray chamber 19 and is ultimately sprayed out of the spray ports 25, where it diffuses and disinfects the surrounding area. Because disinfectant must be present within the atomizing housing 12, and the depth of the disinfectant (i.e., the depth to which the disinfectant submerges the spray port of the atomizing generator 13) significantly affects the atomization effect, this embodiment further includes a float valve 10 within the atomizing housing 12 to control the disinfectant liquid level. This float valve 10 is conventional and has a liquid inlet 7 extending outward from the atomizing housing 12. Disinfectant is injected through the liquid inlet to a set liquid level. The float valve 10 of this embodiment controls the injection of disinfectant into the atomizing housing 12 and is a purely mechanical structure, which is not prone to damage and is simple and reliable.

[0039] In this embodiment, a roller shutter 29 is provided between the traction member 8 and the bottom of the window 30. The upper end of the roller shutter 29 is fixed to the traction member 8, and the lower end is fixed to the bottom of the window 30. The roller shutter 29 rises with the traction member 8 and can block the interior of the workstation when it is unfolded; the roller shutter 29 descends with the traction member 8 and can be retracted when it is folded.

[0040] A position identification device is mounted on the sampling chamber 9 and is used to identify the height of the person being sampled. In this embodiment, the position identification device is a height sensor 32. This sensor identifies the height of the person being sampled and transmits this information to a controller, which then controls the lifting mechanism to adjust to the varying heights of the person being sampled. To ensure effective height identification, the sensor is mounted on the top of the sampling chamber 9 via a height sensor bracket 34.

[0041] The visual recognition and feedback mechanism of this embodiment includes a camera 27 and a display 31. The camera 27 is mounted on the traction member 8 via a camera bracket 28 and rises and falls with the traction member 8 to photograph the face and pharyngeal wall of the person being sampled. In order to facilitate the person being sampled to clearly see the display 31, the display 31 of this embodiment is mounted on the top of the sampling chamber 9 in a hanging manner via a display hanging plate 33. The camera 27, the display 31, the height sensor 32, the lifting drive motor 22, and the proximity switch 17 are respectively connected to the controller, as shown in FIG. Figure 7A 、 Figure 7B As shown, the display 31 first provides a standard facial contour for the sampled person to adjust the facial correspondence; then, the display 31 provides a characteristic image of the pharyngeal area in the oral cavity for the sampled person to adjust the corresponding state of the open exposure of the pharynx.

[0042] Example 2

[0043] like Figure 2 As shown, the difference between this embodiment and the first embodiment is that a first rolling curtain 2901 is provided between the traction member 8 of this embodiment and the top of the window 30, and a second rolling curtain 2902 is provided between the traction member 8 and the bottom of the window 30. The upper end of the first rolling curtain 2901 is fixed to the top of the window 30, and the lower end is fixed to the traction member 8. The upper end of the second rolling curtain 2902 is fixed to the traction member 8, and the lower end is fixed to the bottom of the window 30. The display 31 of the visual recognition and feedback mechanism of this embodiment is embedded in the first rolling curtain 2901 and moves with the first rolling curtain 2901. The height sensor 32 of this embodiment is installed on the outer edge of the top of the sampling chamber, or installed above the traction member 8. The rest is the same as the first embodiment.

[0044] The biological sample collection method of the present invention is:

[0045] The biological sample collection human-computer interaction device of the present invention is used to collect biological samples from a subject. Taking throat swab sampling as an example, a height sensor 32 identifies the subject's height and transmits this information to a controller. The controller then controls the lift drive motor to adjust and raise the traction member 8 based on the height position determined by the subject's head features, moving it to a position appropriate for the subject's height, making the sampling process more comfortable and convenient. The subject bites the mouthpiece 15. During the sampling process, the camera 27 in the visual recognition and feedback mechanism identifies the subject's facial contours and the sampling area within the oral cavity, records the sampling process, and displays it on the display 31. After the sampling swab is taken, the atomizer 13 operates to atomize the disinfectant solution, which is then sprayed from the spray port 25 by the centrifugal blower 11 to disinfect the air near the mouthpiece 15 and the device itself, ensuring a comfortable and smooth sampling process and significantly reducing the possibility of cross-infection between subjects. After disinfection, the negative pressure source draws the disinfected atomized air and any remaining air through the suction port 35 via the pipeline 36 for disposal. The next person to be sampled can follow the above steps.
