DETAILED DESCRIPTION

[0031] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, the detailed description thereof will not be repeated.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0033] Combine the following Figures 1 to 7 The specific working mode of the present invention is described in detail:

[0034] The present invention proposes a sampling head device of a throat swab sampling system, comprising: a flexible clamping and rotating device 1, a slip ring 2, a laser rangefinder 3, a motor 4, a lower shell 5, a crossbeam adapter 6, an upper shell 7, a camera 8, a lighting assembly 9, a mounting plate 10, a clamping plate 11, a support plate 12, and a baffle 13; the lower shell 5 and the upper shell 7 are assembled together to form a closed head chamber.

[0035] The flexible clamping rotating device 1 is used to clamp the throat swab; the flexible clamping rotating device 1 is installed in the head chamber and can drive the throat swab to rotate. The flexible clamping rotating device 1 uses a spring 102 to clamp the throat swab, and the clamping force is gentle, which prevents the throat swab from breaking during clamping; at the same time, when the throat swab encounters a large resistance during sampling, the spring 102 and the throat swab will slide relative to each other, reducing discomfort; the flexible clamping rotating device 1 is provided with a spring 107 and a pressure sensor 109, which improves the comfort of throat swab sampling; at the same time, the pressure sensor 109 can feedback the changes in the pressure value in real time, which improves the safety of throat swab sampling.

[0036] The slip ring 2 is used to transmit the force of the motor 4 driving the flexible clamping rotating device 1 to rotate; the slip ring 2 is installed on the mounting plate 10 in the head cavity and is located between the flexible clamping rotating device 1 and the motor 4.

[0037] The slip ring 2 is an inner and outer ring structure; the inner ring is used to connect the motor 4 and the flexible clamping rotating device 1, and rotates simultaneously with the flexible clamping rotating device 1; the inner ring transmits the force that drives the flexible clamping rotating device 1 to rotate by connecting to the adapter assembly 110; the inner ring is provided with a through hole for passing the circuit of the pressure sensor 109; the outer ring is used to support the inner ring and is fixedly connected to the mounting plate 10.

[0038] The laser rangefinder 3 is used to measure the distance between the sampled person and the sampled person; Figure 7As shown, the laser rangefinder 3 is installed in the groove of the clamping plate 11. The laser beam emitted by the laser rangefinder 3 intersects with the axis of the throat swab at the head position of the throat swab, so as to ensure that the laser rangefinder measures the specific distance between the head of the throat swab and the person being sampled in real time.

[0039] The motor 4 is used to drive the flexible clamping and rotating device 1 to rotate. The motor 4 is installed on the mounting plate 10 in the head chamber. As Figure 1 shown, the central axes of the flexible clamping and rotating device 1, the slip ring 2, and the output shaft of the motor 4 coincide.

[0040] The crossbeam adapter 6 is used to connect with external components. The crossbeam adapter 6 is fixedly connected to the lower shell 5 and the upper shell 7 respectively.

[0041] The upper shell 7 is installed above the lower shell 5. A window for light transmission is opened on the upper shell 7. In an embodiment of the present invention, the lower shell 5 and the upper shell 7 are fixedly connected by threads.

[0042] The camera 8 is used to collect image information. The camera 8 is installed on the support plate 12. The optical axis of the lens of the camera 8 is parallel to the central axis of the flexible clamping and rotating device 1, ensuring that the camera 8 can directly collect the oral image of the person being sampled.

[0043] The lighting component 9 is used to supplement light for the camera 8 when the light is dim; the lighting component 9 is installed on the support plate 12; the optical axis of the lighting component 9 is parallel to the central axis of the flexible clamping and rotating device 1, ensuring that the lighting component 9 directly irradiates the oral cavity of the person being sampled.

[0044] The mounting plate 10 is used to carry the slip ring 2 and the motor 4. As Figure 6 shown, the mounting plate 10 is installed on the lower shell 5 and is located in the head chamber.

[0045] The clamping plate 11 is used to fix and carry the laser rangefinder 3. As Figure 6 and Figure 7 shown, the clamping plate 11 is installed on both sides of the inner wall of the lower shell 5 and is pressed and fixed by the mounting plate 10. A groove for fixing the laser rangefinder 3 is opened on the clamping plate 11. The inclination angle of the groove ensures that the optical path of the laser emitted by the laser rangefinder 3 intersects with the axis of the throat swab at the head position of the throat swab.

[0046] The support plate 12 is used to fix and carry the camera 8 and the lighting component 9. As Figure 1 shown, the support plate 12 is installed on the upper shell 7 and is located in the head chamber. In an embodiment of the present invention, the support plate 12 is fixedly installed on the upper shell 7 by screws.

[0047] The baffle 13 is used to close the window on the upper shell 7. As Figure 1As shown, the baffle 13 is mounted on the upper shell 7 and is located in the head chamber. The baffle 13 is made of transparent material to ensure light transmittance.

[0048] The flexible clamping and rotating device 1 includes a clamping sleeve 101 , a spring 102 , a center rod 103 , a bearing 104 , a linear bearing 105 , a sleeve 106 , a spring 107 , a sensor pressure plate 108 , a pressure sensor 109 , an adapter assembly 110 , and a retaining spring 111 .

[0049] The clamping sleeve 101 is installed at one end of the central rod 103 to carry and fix the throat swab. Figure 3 As shown, in order to facilitate the centering of the throat swab during clamping, the end of the clamping sleeve 101 close to the throat swab is in the shape of a hollow cone, and the inner hole diameter of the hollow cone is the same as the diameter of the rod of the throat swab. When the throat swab is close to the clamping sleeve 101, the rod of the throat swab first contacts the hollow cone, and when the throat swab continues to move, it will be guided by the inner wall of the hollow cone to the inner hole of the hollow cone, ensuring the convenience of centering when the throat swab is clamped. The clamping sleeve 101 is provided with a hole for installing the spring piece 102, and the size and number of the hole correspond to the spring piece 102. In an embodiment of the present invention, the clamping sleeve 101 and the center rod 103 are assembled together in an interference fit manner to ensure that the center rod 103 can drive the clamping sleeve 101 to rotate together.

[0050] The spring pieces 102 are installed in the clamping sleeve 101 to compress the throat swab. To ensure the centration and reliability of the clamping throat swab, in the axial direction of the clamping sleeve 101, the number of spring pieces 102 in a group is at least three, and the installation positions of all spring pieces 102 are collinear; in the radial direction of the clamping sleeve 101, the number of groups of spring pieces 102 is not less than three, and each group of spring pieces 102 is evenly distributed along the circumference.

[0051] like Figure 2 and Figure 3 As shown, in one embodiment of the present invention, three spring pieces 102 are selected as one group, and there are three groups of spring pieces 102 in total. Each group of spring pieces 102 is evenly distributed at an angle of 120° in the radial direction of the clamping sleeve 101. In one embodiment of the present invention, the spring piece 102 is a ejector spring piece.

[0052] like Figure 5 As shown, a part of the center rod 103 is fixed in the sleeve 106 and passes through the linear bearing 105; the other part extends out of the sleeve 106 and is connected to the clamping sleeve 101. The center rod 103 is used to transmit the contact force between the throat swab and the sampled part and drive the clamping sleeve 101 to rotate. A positioning key 301 is provided on one end of the center rod 103 close to the spring 107. The positioning key 301 is used to cooperate with the through groove 601 on the outer cylindrical surface of the sleeve 106 to ensure that the center rod 103 is driven to rotate simultaneously when the sleeve 106 rotates.

[0053] The bearing 104 is mounted on the outer cylindrical surface of the sleeve 106 and is constrained by the shaft shoulder on the outer cylindrical surface of the sleeve 106. The bearing 104 is fixed by the inner wall of the lower shell 5 and the inner wall of the upper shell 7. The bearing 104 is used to carry the flexible clamping rotating device 1.

[0054] The linear bearing 105 is installed inside the sleeve 106, axially fixed by the retaining spring 111, and sleeved on the center rod 103. The linear bearing 105 is used to support and lubricate the center rod 103.

[0055] like Figure 4 As shown, the sleeve 106 is used to carry various components inside and drive the center rod 103 to rotate. A through groove 601 is provided on the outer cylindrical surface of the sleeve 106 at one end close to the adapter assembly 110; the through groove 601 cooperates with the positioning key 301 on the center rod 103 to ensure that the sleeve 106 drives the center rod 103 to rotate simultaneously when the sleeve 106 rotates. A shoulder for axially positioning the bearing 104 is provided on the outer cylindrical surface of the sleeve 106. A groove for fixing the retaining ring 111 is provided inside the sleeve 106.

[0056] The spring 107 is installed inside the sleeve 106 and is located between the central rod 103 and the sensor pressing plate 108. The spring 107 is used to buffer the movement impact of the central rod 103 to ensure that the throat swab is sampled gently. The spring 107 is constrained and fixed by the annular groove on the sensor pressing plate 108.

[0057] The sensor pressing plate 108 is installed inside the sleeve 106. It is used to transmit force and press the pressure sensor 109 onto the adapter assembly 110. One end of the sensor pressing plate 108 is provided with an annular groove for fixing the spring 107, and the size of the annular groove is the same as that of the spring 107.

[0058] The pressure sensor 109 is installed inside the sleeve 106 and is located between the sensor pressure plate 108 and the adapter assembly 110. The pressure sensor 109 is used to measure the contact pressure between the throat swab and the sampled part. The pressure sensor 109 uses a thin film sensor. The pins of the pressure sensor 109 pass through the through holes on the adapter assembly 110, are connected to the slip ring 2 and the external components, and transmit specific pressure data.

[0059] The adapter assembly 110 is installed at one end of the sleeve 106, and is used to connect with the slip ring 2 and ensure the sealing of the sleeve 106. The adapter assembly 110 is provided with a through hole for the pin of the pressure sensor 109 to pass through.

[0060] The retaining spring 111 is installed in the inner groove of the sleeve 106 to fix the linear bearing 105 .

[0061] The working principle of the sampling head device of the throat swab sampling system proposed by the present invention is as follows: The laser rangefinder 3 monitors the distance between the sampling head device and the person to be sampled in real time; the camera 8 collects and stores the oral images of the person to be sampled in real time for subsequent image processing; the lighting component 9 provides supplementary light in real time; when the throat swab enters the oral cavity of the person to be sampled, the motor 4 starts to drive the flexible clamping and rotating device 1 and the throat swab to rotate; the sampling head device is controlled by an external device to move. When the throat swab carried by the sampling head device moves to the designated sampling site, the throat swab contacts the sampling site, and the pressure sensor 109 in the flexible clamping and rotating device 1 feeds back the change of the contact pressure in real time; when the pressure value reaches a certain magnitude, the external device stops moving the sampling head device, and the flexible clamping and rotating device 1 drives the throat swab to rotate in real time to perform the sampling work. After the sampling is completed, the rotating motor 4 stops working, and the sampling head device is driven back by the external device to complete the automatic sampling.

[0062] In summary, the present invention proposes a sampling head device of a throat swab sampling system. The present invention realizes the real-time monitoring of the moving distance, automatic throat swab sampling, and real-time detection of the interaction force with the human body through the flexible clamping and rotating device 1, the laser rangefinder 3, the motor 4, and the camera 8, improving the motion accuracy while ensuring the safety of people and equipment and the comfort of collection; after being connected to an external automatic control component, the present invention can automatically perform the work of throat swab sampling, avoiding the phenomenon of secondary infection when doctors perform artificial sampling, reducing the labor intensity, and improving the efficiency and safety of the sampling work; the present invention avoids the design method of traditional robotic arms, reduces the overall equipment cost, and has a simple overall structure, which is easy to manufacture and use.
