[0064] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0065] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0066] Combine Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a throat swab sampling device, which includes a mounting member 1, a fixed member 2 and a movable member 3; a connecting portion 11 for connecting to an external device is provided on one side of the mounting member 1; the fixed member 2 is fixedly connected to the other side of the mounting member 1 via at least a first sensor 21 and a second sensor 22; the movable member 3 is connected to the side of the fixed member 2 facing away from the mounting member 1 via an elastic movable component 4, and a clamping mechanism 5 for clamping a swab 7 is provided on the other opposite side of the movable member 3;

[0067] Among them, the first sensor 21 and the second sensor 22 are arranged at intervals on opposite sides of the fixing part 2, and can detect the pressure and / or tension between the fixing part 2 and the mounting part 1; the elastic movable component 4 can shrink and deform under pressure to drive the movable part 3 and the swab to move parallel or tilted toward the fixing part 2.

[0068] The throat swab sampling device can be used in conjunction with a sampling manipulator, and the working process may include swab clamping, flexible collection and manipulator resetting.

[0069] During the swab clamping process, the clamping mechanism 5 in the movable part 3 clamps and fixes the swab 7; during the flexible collection process, the sampling manipulator drives the pharyngeal swab sampling device to perform oral wiping and collection on the posterior pharyngeal wall of the person being collected. When the swab 7 contacts the posterior pharyngeal wall, the posterior pharyngeal wall generates a backward pressure F on the swab 7. At this time, the first sensor 21 and the second sensor 22 can detect the real-time pressure between the fixing part 2 and the mounting part 1. When the real-time pressure is too large, under the control of the force control algorithm, the execution arm in the sampling manipulator can drive the pharyngeal swab sampling device to move backward to reduce the pressure on the posterior pharyngeal wall of the person being collected, and the sampling manipulator can adjust its own wiping force according to the actual pressure changes of the first sensor 21 and the second sensor 22.

[0070] Moreover, since the movable part 3 is connected to the side of the fixed part 2 facing away from the mounting part 1 through the elastic movable component 4, the elastic movable component 4 can also shrink and deform under the action of the pressure F, and the movable part 3 and the swab can move parallel or tilted toward the fixed part 2. In this way, the elastic movable component 4 can achieve the effective effect of actively and adaptively adjusting the pressure of the swab 7 on the posterior pharyngeal wall of the collector, and interact with the detection adjustment of the first sensor 21 and the second sensor 22, so as to fully ensure that the person being collected is safer and more comfortable during the automatic collection of the oral swab.

The linear bearing 42 can be installed and fixed in the movable part 3 along the thickness direction by a retaining spring, and the flexible spring 43 is arranged below the linear bearing 42. In this way, when the swab 7 contacts the patient being collected and is under pressure, the movable guide shaft 41 can slide downward relative to the linear bearing 42 and correspondingly squeeze the flexible spring 43, so that the movable part 3 is pressed downward under the elastic deformation of the elastic movable component 4, adaptively adjusting the pressure of the swab 7 on the posterior pharyngeal wall of the collector, and ensuring that the patient being collected will not be harmed by the wiping pressure of the swab 7.

[0077] The specific configuration of the elastic movable component 4 has a simple structure, can flexibly and sensitively adapt to stress deformation, and fully ensures that the swab 7 has moderate force when wiping.

[0078] In one embodiment, multiple elastic movable components 4 are provided in the corners of the movable member 3 ; the multiple movable guide shafts 41 in the multiple elastic movable components 4 can move and retract relative to the linear bearing 42 along the thickness direction individually or simultaneously.

[0079] Specific, combined Figure 2 and Figure 3To further explain in detail, four elastic movable components 4 are specifically arranged in a one-to-one correspondence at the four corners of the movable part 3, so that the four movable guide shafts 41 in the four elastic movable components 4 can be moved and retracted relative to the linear bearing 42 along the thickness direction individually or simultaneously, so that the relative spacing and relative inclination angle between the movable part 3 and the fixed part 2 can be fully and flexibly adjusted, so that the force and angle of the swab 7 during wiping and collection can be flexibly and adaptively adjusted.

[0080] The specific configuration of the elastic movable component 4 has the beneficial effects of being simple in structure and being able to flexibly and adaptively adjust the force and angle of the swab 7 during wiping and collection.

[0081] In one embodiment, the elastic movable component 4 further includes a limit stopper 44 ; the limit stopper 44 is fixedly disposed on the top end of the movable guide shaft 41 and forms a limit blocking mechanism with the moving member 3 .

[0082] Specific, combined Figure 2 Further detailed description, the elastic movable component 4 also specifically includes a limit block 44, and the limit block 44 is fixedly arranged at the top end of the movable guide shaft 41, so that the limit block 44 can correspond to the recessed mounting hole position in the movable part 3 to form a limit blocking mechanism, thereby forming a limitation on the moving range of the corresponding movable part 3.

[0083] The specific arrangement of the above-mentioned limit stopper 44 has the beneficial effects of being simple in structure and being able to controllably limit the moving range of the movable member 3 .

[0084] In one embodiment, the clamping mechanism 5 includes a clamping member 51 and a driving motor 52; the clamping member 51 is movably embedded in the sliding groove 31 in the movable member 3; the driving motor 52 is connected to the clamping member 51 through the transmission mechanism 6, and is used to drive the clamping member 51 to move back and forth in the sliding groove 31; wherein, the clamping member 51 and the sliding groove 31 are respectively provided with a recessed V-shaped bayonet, and the two V-shaped bayonet can correspond to form a clamping port for clamping a swab.

[0085] Specific, combined Figure 3 To further explain in detail, the clamping mechanism 5 is specifically configured to include a clamping part 51 and a driving motor 52, and the driving motor 52 can be specifically configured to be a stepping motor, and the driving motor 52 transmission mechanism 6 is connected to the clamping part 51, which can drive the clamping part 51 to move back and forth in the sliding groove 31, so that the recessed V-shaped bayonet openings corresponding to the clamping part 51 and the sliding groove 31 can cooperate to form a clamping port for clamping the swab.

[0086] Moreover, two of the above-mentioned driving motors 52 can be provided accordingly, and a reducer can also be provided to reduce the speed of the stepping motor so as to increase the output torque of the stepping motor.

[0087] In one embodiment, the transmission mechanism 6 includes a traction rope 61, a sheave 62 and a guide member 63; one end of the traction rope 61 is connected to the clamp 51; the sheave 62 is arranged on the output shaft of the drive motor 52, and the other end of the traction rope 61 is connected to the annular groove in the circumferential surface of the sheave 62; the guide member 63 is arranged along the extension direction of the sliding groove 31, for guiding and limiting the sliding direction of the clamp 51; wherein the drive motor 52 can drive the sheave 62 to reel or unreel the traction rope 61, so that the clamp 51 slides back and forth in the sliding groove 31.

[0088] Specific, combined Figure 4 To further explain in detail, the transmission mechanism 6 is specifically configured to include a traction rope 61, a sheave 62 and a guide member 63, and one end of the traction rope 61 is connected to the clamp 51, and the other end is connected to the annular groove in the circumferential surface of the sheave 62, so that the driving motor 52 can drive the sheave 62 to reel or unreel the traction rope 61, thereby pulling the clamp 51 to slide back and forth in the sliding groove 31 through the traction rope 61, and the guide member 63 arranged along the extension direction of the sliding groove 31 can also guide and limit the sliding direction of the clamp 51, so that the clamping sliding movement of the clamp 51 is more precise.

[0089] In one embodiment, the guide member 63 includes a guide shaft 631 and a compression spring 632; the guide shaft 631 is installed on the clamp 51 along the extension direction of the sliding groove 31, and one end of the compression spring 632 abuts against the clamp 51, and the other end abuts against the sliding groove 31, which is used to apply a compressive elastic force to the clamp 51; wherein, a plurality of guide members 63 are arranged in the sliding groove 31, and the clamp 51 can slide relative to the guide shaft 631 and squeeze the compression spring 632.

[0090] Specific, combined Figure 3 and Figure 4 To further explain in detail, the guide member 63 is specifically configured to include a guide shaft 631 and a compression spring 632, and the compression spring 632 can be sleeved on the outside of the guide member 63, and one end abuts against the clamping member 51, and the other end abuts against the sliding groove 31, so that the compression spring 632 can apply a compression elastic force to the clamping member 51. When the driving motor 52 no longer drives the clamping member 51, the compression spring 632 can cause the clamping member 51 to perform a reset movement.

[0091] The specific arrangement of the guide member 63 has the beneficial effects of simple structure, precise guidance of the clamping member 51, and movement reset.

[0092] In one embodiment, the transmission mechanism 6 further includes a winding sheave 64 ; the winding sheave 64 is installed on the moving member 3 via a fixing pin 641 ; and the traction rope 61 is wound around the circumference of the winding sheave 64 .

[0093] Specific, combined Figure 4 To further explain in detail, a winding groove wheel 64 is also provided in the transmission mechanism 6, and the winding groove wheel 64 is installed on the movable part 3 through a fixing pin 641, and the traction rope 61 is wound around the circumference of the winding groove wheel 64. In this way, the traction direction of the traction rope 61 can be changed through the winding groove wheel 64, so that the structure of the transmission mechanism 6 can be more compact.

[0094] The swab clamping process of the throat swab sampling device: Figure 3 As shown, when the flexible manipulator is in its initial state, the clamp 51 is positioned at the edge of the sliding slot 31, squeezed by multiple compression springs 632. When the manipulator needs to grasp a swab 7, the drive motor 52 rotates, driving the traction rope 61 around the winding sheave 64 and around the circumference of the sheave 62. This rewinds the traction rope 61, pulling the clamp 51 along the guide shaft 631 to secure the swab 7. The clamping force is provided by the drive motor 52 and the resistance provided by the multiple compression springs 632.

[0095] The flexible collection process of the throat swab sampling device: Figure 5 As shown, when the flexible robotic gripper grasps a swab 7 to collect oral pharyngeal blood from a patient, the swab 7 contacts the posterior pharyngeal wall, exerting a backward pressure F on the swab. Under the swab's pressure, the movable element 3 moves backward along the elastic movable assembly 4, with the flexible spring 43 in the elastic movable assembly 4 providing a counterforce. The addition of active flexibility ensures that the patient is not injured. Simultaneously, the first and second sensors 21 and 22 generate pressure changes ∆F1 and ∆F2, respectively. These pressure changes are equal to the pressure exerted by the swab on the patient, i.e., F = ∆F1 + ∆F2. The combination of the active, adaptively contracting flexible spring 43 and the passively detecting first and second sensors 21 and 22 ensures greater patient safety and comfort during oral swab collection. When the pressure values ​​detected by the first and second sensors 21 and 22 reach a set threshold, the robotic gripper, carrying the swab, moves up and down the patient's posterior pharyngeal wall, driven by the actuator arm. Furthermore, the friction force f exerted by the swab 7 on the patient's posterior pharyngeal wall during the wiping process can be calculated based on the pressure changes ∆F1 and ∆F2. The first sensor 21 and the second sensor 22 work together to measure the positive pressure exerted by the swab 7 on the posterior pharyngeal wall and the frictional resistance generated during wiping. When the positive pressure or frictional resistance is too high, the force control algorithm controls the actuator arm in the manipulator to move backward with the flexible manipulator to reduce the pressure on the patient's posterior pharyngeal wall.

[0096] The throat swab sampling device resets: After oral swab collection is complete, the manipulator's actuator arm carries the throat swab sampling device out of the patient's mouth. At this point, the movable element 3, under the elastic force of multiple flexible springs 43, moves along the movable guide shaft 41 to reset. When the manipulator needs to release the swab, the drive motor 52 rotates in the opposite direction and releases the traction rope 61, causing the clamp 51 to release the swab 7. During the outward sliding process, the clamp 51 is powered by multiple compression springs 632.

[0097] In one embodiment, resistance-increasing gaskets are respectively provided in the V-shaped bayonet.

[0098] Specific, combined Figure 3 To further explain in detail, resistance-increasing gaskets are respectively provided in the V-shaped bayonet. The resistance-increasing gaskets can be, but are not limited to, rubber gaskets, silicone gaskets, sponge gaskets, etc., to increase the clamping stability of the V-shaped bayonet on the swab 7.

[0099] In one embodiment, one of the two side surfaces of the movable part 3 and the fixed part 2 facing each other is provided with a recessed portion and the other is provided with a corresponding raised portion; when the movable part 3 moves toward the fixed part 2, the raised portion is correspondingly engaged with the recessed portion.

[0100] Specific, combined Figure 4 To further explain in detail, on the two side surfaces of the movable part 3 and the fixed part 2 facing each other, one is provided with a recessed portion and the other is provided with a corresponding raised portion. In this way, when the movable part 3 moves toward the fixed part 2, the raised portion is correspondingly engaged and inserted into the recessed portion, thereby further improving the relative stability of the relative positions of the movable part 3 and the fixed part 2.

[0101] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0102] The above are only specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure.
