[0064] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are 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] Combination Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a throat swab sampling device, which includes a mounting member 1, a fixing member 2 and a moving member 3; a connecting portion 11 for connecting to an external device is provided on one side of the mounting member 1; the fixing member 2 is fixedly connected to the other side of the mounting member 1 through at least a first sensor 21 and a second sensor 22; the moving member 3 is connected to a side of the fixing member 2 facing away from the mounting member 1 through an elastic movable component 4, and a clamping mechanism 5 for clamping a swab 7 is provided on the other opposite side of the moving 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 can 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 effectively achieve the 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 and 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.

[0071] In summary, the throat swab sampling device provided in the embodiments of the present disclosure has at least the following beneficial effects:

In this way, when the swab 7 contacts the collected patient and is subjected to 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 moving part 3 is pressed downward under the elastic deformation of the elastic movable component 4, and the pressure of the swab 7 on the posterior pharyngeal wall of the collector is adaptively adjusted, ensuring that the collected patient will not be injured 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 a moderate force when wiping.

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

[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 stop mechanism with the moving member 3 .

[0082] Specific, combined Figure 2 Further detailed description, the elastic movable component 4 also specifically includes a limit stop block 44, and the limit stop block 44 is fixedly arranged at the top end of the movable guide shaft 41, so that the limit stop block 44 can correspond to the recessed mounting hole in the movable part 3 to form a limit locking 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 simple structure and being able to controllably limit the moving range of the moving 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 correspondingly provided with a recessed V-shaped bayonet, and the two V-shaped bayonet can correspond to cooperate 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 member 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 member 51 for driving, and can drive the clamping member 51 to reciprocate in the sliding groove 31, so that the corresponding recessed V-shaped snap-fits of the clamping member 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 stepper motor so as to increase the output torque of the stepper motor.

[0087] In one embodiment, the transmission mechanism 6 includes a traction rope 61, a groove wheel 62 and a guide member 63; one end of the traction rope 61 is connected to the clamp 51; the groove wheel 62 is arranged on the output shaft of the driving motor 52, and the other end of the traction rope 61 is connected to the annular groove in the peripheral surface of the groove wheel 62; the guide member 63 is arranged along the extension direction of the sliding groove 31, and is used to guide and limit the sliding direction of the clamp 51; wherein the driving motor 52 can drive the groove wheel 62 to reel in 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 groove wheel 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 groove wheel 62, so that the driving motor 52 can drive the groove wheel 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, 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 clamp 51, and the other end abuts against the sliding groove 31, so that the compression spring 632 can apply a compressive elastic force to the clamp 51. When the driving motor 52 no longer drives the clamp 51, the compression spring 632 can cause the clamp 51 to perform a reset movement.

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

[0092] In one embodiment, the transmission mechanism 6 further includes a winding groove wheel 64 ; the winding groove wheel 64 is installed on the moving member 3 through a fixing pin 641 ; and the traction rope 61 is wound around the circumference of the winding groove wheel 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 periphery of the winding groove wheel 64, so that 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 is as follows: Figure 3 As shown, when the flexible manipulator is in the initial state, the clamping member 51 is at the edge of the sliding slot 31 under the pressure of the multiple compression springs 632. When the manipulator needs to work to grab the swab 7, the drive motor 52 rotates and drives the traction rope 61 to bypass the winding groove wheel 64 and wrap around the circumference of the groove wheel 62, thereby realizing the function of winding the traction rope 61, pulling the clamping member 51 to move along the guide shaft 631, and clamping and fixing the swab 7. At this time, the power for clamping comes from 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 mechanical claw clamps the swab 7 to collect the patient's posterior pharyngeal wall, when the swab 7 contacts the posterior pharyngeal wall, the posterior pharyngeal wall generates a backward pressure F on the swab. At this time, the moving part 3 moves backward along the elastic movable component 4 under the pressure of the swab, and the flexible spring 43 in the elastic movable component 4 provides an elastic force in the opposite direction. The addition of active flexibility ensures that the patient will not be injured. At the same time, the first sensor 21 and the second sensor 22 generate pressure changes ΔF1 and ΔF2, and the pressure changes generated by the two sensors are equal to the pressure generated by the swab on the patient, that is, F = ΔF1 + ΔF2. The combination of the active adaptive contraction flexible spring 43 and the passive detection first sensor 21 and the second sensor 22 makes the patient safer and more comfortable during the oral swab collection process. When the pressure value detected by the first sensor 21 and the second sensor 22 reaches the set threshold, the manipulator carries the swab and wipes the patient's posterior pharyngeal wall up and down under the drive of the actuator arm. In addition, the friction force f generated by the swab 7 on the posterior pharyngeal wall of the collected patient during the wiping process can also be calculated according to the pressure changes ΔF1 and ΔF2. The first sensor 21 and the second sensor 22 can cooperate to measure the positive pressure generated by the swab 7 on the posterior pharyngeal wall and the friction resistance generated during the wiping process. When the positive pressure or friction resistance is too large, under the control of the force control algorithm, the actuator arm in the manipulator should carry the flexible manipulator to move backward to reduce the pressure on the posterior pharyngeal wall of multiple patients.

[0096] The reset process of the throat swab sampling device: After the oral swab is collected, the execution arm in the manipulator carries the throat swab sampling device out of the patient's mouth. At this time, the moving part 3 moves along the movable guide shaft 41 under the elastic force of multiple flexible springs 43 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, so that the clamp 51 releases the swab 7. During the process of the clamp 51 sliding outward, the power of the clamp 51 comes from multiple compression springs 632.

[0097] In one possible implementation manner, resistance-enhancing gaskets are respectively provided in the V-shaped bayonet.

[0098] Specific, combined Figure 3 For further detailed description, resistance-enhancing gaskets are respectively arranged in the V-shaped bayonet, and the resistance-enhancing 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, among the two side surfaces of the movable member 3 and the fixed member 2 facing each other, one is provided with a recessed portion and the other is provided with a corresponding raised portion; when the movable member 3 moves toward the fixed member 2, the raised portion is correspondingly engaged and inserted into the recessed portion.

[0100] Specific, combined Figure 4 To further explain in detail, among the two side surfaces of the movable member 3 and the fixed member 2 facing each other, one is provided with a recessed portion and the other is provided with a corresponding raised portion, so that when the movable member 3 moves toward the fixed member 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 member 3 and the fixed member 2.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
