[0020] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through a nasopharyngeal adenoid collector according to some embodiments of the present disclosure, the sampling steps can be simplified, thereby shortening the sampling time, reducing the contamination of the sample in the nasal cavity and the contamination of the sample in the air, and improving the user experience. The reasons why the existing technology has many sampling steps, long sampling time, many cases of sample contamination in the nasal cavity and the contamination of the sample in the air, and poor user experience are: when using a swab for sampling, since it only includes a single swab rod and a single sampling head, only cell samples or secretion samples can be collected at a time; the rigid swab rod is easy to damage the nasal mucosa during the sampling process, resulting in a poor user experience and sample contamination; the swab rod needs to be broken to obtain the sample, resulting in many sampling steps and a long sampling time; the swab rod is easily contaminated with nasal contaminants during the process of entering and exiting the nasal cavity during sampling; and after the sampling is completed, when the swab rod's easy-to-break point is placed against the tube mouth and force is applied to break the swab rod from the easy-to-break point, the sampling head is exposed to the air for a long time, causing sample contamination. Based on this, some embodiments of the nasopharyngeal adenoid collector disclosed herein are characterized in that the nasopharyngeal adenoid collector includes an inner sampling structure, a middle sampling structure and an outer protective structure, wherein the inner sampling structure includes a metal wire, a base and a brush sampling head, wherein the head end of the metal wire is connected to the brush sampling head, and the tail end of the metal wire is connected to the base; the middle sampling structure includes a metal tube, a middle tube seat and a net bag sampling structure, wherein the head end of the metal tube is connected to the net bag sampling structure, and the tail end of the metal tube is connected to the middle tube seat; the outer protective structure includes an outer tube seat and a sheath tube, wherein the outer tube seat is connected to the tail end of the sheath tube, and the outer protective structure is used The inner sampling structure is embedded in the middle sampling structure, which is embedded in the outer protective structure. The inner and middle sampling structures are connected, and the front end of the sheath is provided with an arc-shaped protective edge. The inner and middle sampling structures can rotate independently for sampling. When in use, the base is pressed to squeeze the drive structure provided between the middle sampling structure and the outer protective structure, causing the brush sampling head and the net sampling structure to pop out. The base is rotated to engage the middle tube holder with the circumferential groove provided in the outer tube holder, allowing sampling to be performed through the brush sampling head and the net sampling structure. Because the inner and middle sampling structures of the nasopharyngeal adenoid collector can rotate synchronously during a single sampling operation to capture mucus secretions and desquamated epithelial cells on the surface of the adenoids, the sampling process can be simplified, the sampling time can be shortened, and the number of sampling times can be reduced.Because the inner sampling structure and the middle sampling structure are located inside the outer protective structure, they can provide protection for the inner sampling structure and the middle sampling structure when entering and exiting the nasal cavity, thereby reducing the sampling head from being contaminated by pollutants in the nasal passage and the exposure of the sample to air pollution after sampling. The arc-shaped contour design of the arc-shaped protective edge also reduces damage to the nasal mucosa. As a result, the sampling steps can be simplified, thereby shortening the sampling time, reducing the contamination of the sample in the nasal cavity and the contamination of the sample in the air, and improving the user experience.

[0044] In some embodiments, as Figure 1 As shown, the inner sampling structure is embedded in the middle sampling structure. The middle sampling structure is embedded in the outer protective structure. The inner sampling structure and the middle sampling structure are connected. The inner sampling structure and the middle sampling structure can rotate synchronously to perform sampling in a single sampling.

[0045] Alternatively, as Figure 3 As shown, the net bag sampling structure 6 includes a net frame and a net bag. The net frame is made of memory alloy wire, and the net bag is made of polymer material. The pore size of the net bag ranges from 100 to 120 μm, and the diameter of the net frame ranges from 2.8 to 3.2 mm. The net bag can be used to sample cells on the surface of the adenoids. The net bag can be made of polymer mesh. For example, the memory alloy wire frame can be made of nickel-titanium alloy wire, and the polymer mesh can be made of polyethylene.

The initial state of the spring 19 is the expanded state. The spring 19 provides a buffering effect when the inner and middle sampling structures are used for sampling, thereby slowing down the speed at which the inner and middle sampling structures enter the nasal cavity. After the inner and middle sampling structures have taken samples, the spring 19 can drive the inner and middle sampling structures to retract the inner and middle sampling structures into the outer protective structure.

The middle tube seat 4 is rotated so that the limit block 18 provided on the outside of the middle tube seat 4 is clamped into the axial groove 14 provided in the outer tube seat 7. The base 1 is pressed to squeeze the driving structure provided between the middle sampling structure and the outer protective structure, so that the brush sampling head 3 and the net bag sampling structure 6 are ejected. The base 1 is rotated so that the middle tube seat 4 is clamped into the second continuous circumferential groove 16 of the outer tube seat 7. The base 1 is rotated so that the brush sampling head 3 and the net bag sampling structure 6 are sampled. The size setting of the base 1, the middle tube seat 4, and the outer tube seat 7 can achieve a better sampling operation effect. Here, the size of the base 1, the middle tube seat 4, and the outer tube seat 7 is not limited and can be adjusted according to actual needs. The diameter of the base 1 is within a range that provides a stable foundation, reducing tilting or sliding of the device during sampling. The material of the base 1 serves as the bottom support of the sampler, improving overall stability. The diameter of the middle tube holder 4 is within a range that can adapt to the internal metal tube or sampling component, providing a fixed and guiding function. The diameter of the outer tube holder 7 is within a range that can serve as an external protective cover or connection interface, enhancing the sealing and stability of the device.

[0053] In the process of adopting technical solutions to solve the above technical problems, the following technical problem 2 is often accompanied: when users take nasopharyngeal adenoid samples from children, the children may feel uncomfortable and move during the sampling process, which may cause damage to the nasal tissue of the children, resulting in a higher risk of sampling, and the children need to be sampled multiple times, which makes sampling difficult and time-consuming; the sampling structure is not inspected before sampling, resulting in the damaged sampling structure causing damage to the nasopharyngeal adenoids and the collected samples being contaminated, which requires multiple sampling. In response to the above technical problem 2, the conventional solution is generally: sampling only through the swab rod of the bent nasal swab. The inventors took into account the shortcomings of sampling only through the swab rod of the bent nasal swab, and combined with the advantages of the inventor's company in the research and development of nasopharyngeal adenoid sampler structures, we decided to adopt the following solution:

[0054] Optionally, the outer protective structure may further include reflective ceramic markings, a protective film, a visual sensor, a processor, an audio playback component, an infrared thermal imaging sensor, and a resistance strain gauge. The protective film may be a disposable polyethylene film and may be sleeved over the outer protective component. The visual sensor may be fixed to the inner side of the opening of the sheath 8. The processor may be integrated into the sheath 8. The audio playback component may be disposed on the surface of the outer tube socket 7 of the outer protective structure. The infrared thermal imaging sensor may be integrated into the front opening of the sheath 8. The resistance strain gauge may be adhered to the surface of the spring. The reflective ceramic markings may be a composite structure combining a ceramic substrate and a reflective material and may be welded to the inner wall of the outer protective structure near the circumference of the tube opening. The processor may be an instrument that processes various information. For example, the processor may be a central processing unit. For example, the infrared thermal imaging sensor may be a microbolometer. The processor may be in communication with the visual sensor, the audio playback component, the infrared thermal imaging sensor, and the resistance strain gauge. The processor can be connected to an audio amplifier module via the DAC interface of the STM32 main control chip. The audio amplifier module can be a PAM8403. It should be noted that the communication connection can include, but is not limited to, 3G / 4G, WiFi, Bluetooth, WiMAX, Zigbee, UWB (ultra wideband), and other currently known or future communication methods. The resistance strain gauge can be a device that senses a user pressing the base and emits a voltage signal. The visual sensor can be a miniature camera.

[0055] The processor is further configured to perform the following steps:

[0056] In the first step, in response to detecting that the voltage signal of the resistance strain gauge meets a preset sampling start condition, the following steps are performed:

[0057] The first sub-step includes receiving sampling head image information of the brush sampling head and net bag image information collected by the visual sensor. The sampling head image information may represent an image of the brush sampling head before sampling. The net bag image information may represent an image of the net bag before sampling. The preset sampling initiation condition may be detecting that the voltage signal of the resistance strain gauge is greater than 1.2V.

[0058] The second sub-execution step is to determine whether the middle-layer sampling structure and the inner-layer sampling structure meet the preset replacement condition based on the sampling head image information and the net bag image information of the net bag. The preset replacement condition can be that the detection result information corresponding to the sampling head image information or the net bag image information indicates that the detection is unqualified. In practice, first, the processor can detect the sampling head image information and the net bag image information through the YOLOv7 model to obtain the detection result information corresponding to the sampling head image information and the detection result information corresponding to the net bag image information. The obtained detection result information can indicate that the detection is qualified or unqualified. Then, in response to determining that the detection result information indicates that the detection is unqualified, it is determined that the middle-layer sampling structure and the inner-layer sampling structure meet the preset replacement condition. Finally, in response to determining that the detection result information indicates that the detection is qualified, it is determined that the middle-layer sampling structure and the inner-layer sampling structure do not meet the preset replacement condition.

[0059] The third sub-step is to control the audio playback component to play the sampling structure replacement information in response to determining that the brush sampling head or the net bag meets the preset replacement condition. The audio playback component can be a speaker for playing the sampling structure replacement information. The specific type of the audio playback component is not limited here. The sampling structure replacement information can represent information that prompts the user to replace the brush sampling head or the net bag. For example, the sampling structure replacement information can be: "Please replace the brush sampling head."

[0060] The fourth sub-step includes receiving infrared image information captured by the infrared thermal imaging sensor in response to determining that the brush sampling head or the net bag does not meet the preset replacement condition. The infrared image information may represent an infrared image of the user's nasopharyngeal adenoids captured by the infrared thermal imaging sensor. The infrared thermal imaging sensor may be configured to generate an infrared image of the nasopharyngeal adenoids by absorbing infrared radiation from the nasopharyngeal adenoids. The specific type of the infrared thermal imaging sensor is not limited herein.

[0061] The fifth sub-step involves determining, based on the infrared image information, sampling area information corresponding to the nasopharyngeal adenoid collector. The sampling area information may represent a sampling area of ​​the nasopharyngeal adenoids in the infrared image information. The sampling area of ​​the nasopharyngeal adenoids may represent the region within which the nasopharyngeal adenoids are located in the infrared image information. In practice, the processor may identify the region within which the nasopharyngeal adenoids are located in the infrared image information using an edge detection method.

[0062] The sixth sub-step is to segment the infrared image information based on the sampling area information to obtain target sampling area image information corresponding to the sampling area information. The target sampling area image information may represent an image corresponding to the sampling area information segmented from the infrared image information. In practice, the processor may segment the infrared image information based on the sampling area information using an adaptive threshold segmentation algorithm to obtain target sampling area image information.

[0063] The above technical solution, as an inventive feature of an embodiment of the present disclosure, solves the second technical problem: "Sampling children is dangerous, difficult, and time-consuming; a damaged sampling structure can easily damage the nasopharyngeal adenoids and contaminate the collected sample, requiring multiple sampling." The reasons for this low safety are as follows: when users perform nasopharyngeal adenoid sampling on children, the child may feel uncomfortable and move during the sampling process, which can easily cause damage to the child's nasal tissue, resulting in a high risk of sampling and the need for multiple sampling. Sampling children is difficult and time-consuming; the sampling structure is not inspected before sampling, resulting in a damaged sampling structure damaging the nasopharyngeal adenoids and contaminating the collected sample, requiring multiple sampling. If the above factors are resolved, the risk of sampling children can be reduced; and during the sampling process, the difficulty and time of sampling for children can be reduced, and the contamination of the collected sample, resulting in the need for multiple sampling, can be reduced. To achieve this effect, the outer protective structure of the present disclosure can also include reflective ceramic marking points, a protective film, a visual sensor, a processor, an audio playback component, an infrared thermal imaging sensor, and a resistance strain gauge. Wherein, the protective film can be a disposable polyethylene film, which can be sleeved on the outer protective component. Thus, the protective film can reduce the friction between the rigid swab and the nasal mucosa, and the protective film can reduce the sense of intrusion of the rigid swab, so as to improve the experience of children when sampling, thereby reducing the damage caused by activities due to discomfort of children and reducing the risk of sampling. And the reflective ceramic marking points set can be used to increase the brightness in the nasal cavity, so as to facilitate the determination of the position of the nasopharyngeal adenoids, thereby improving the clarity of the captured image, and then improving the accuracy of determining the position of the nasopharyngeal adenoids, so as to reduce the difficulty of sampling. And the processor can control the audio playback component to play the sampling structure replacement information in response to determining that the brush sampling head or the net bag meets the preset replacement conditions. The user can replace the damaged brush sampling head or net bag in time through the sampling structure replacement information played by voice. In this way, the damage to the nasopharyngeal adenoids caused by the damaged sampling structure and the contamination of the collected samples due to the failure to inspect the sampling structure before sampling can be reduced, the accuracy of determining the sampling area can be improved, and the sampling situation can be reduced. It can also reduce the difficulty of sampling for children and shorten the sampling time.

[0064] In the process of adopting technical solutions to solve the above technical problems, the following technical problem three is often accompanied: in the home scenario, when users are taking samples, due to unclear sampling positions, it is easy to misjudge the sampling positions and collect invalid samples, which can easily cause damage to the nasal tissues; since it is impossible to judge whether the amount of collected samples meets the standards during the sampling process, users usually find that the amount of collected samples does not meet the standards after the sampling is completed and that effective sampling results cannot be obtained. Re-sampling is required, which causes cumbersome sampling operations and long sampling times. In response to the above technical problem three, the conventional solution is generally: sampling by referring to the position picture of the nasopharyngeal adenoids. The inventors took into account the shortcomings of sampling by referring to the position picture of the nasopharyngeal adenoids, and combined with the advantages of the inventor's company in the development of nasopharyngeal swab samplers, we decided to adopt the following solution:

[0065] Optionally, the processor may be further configured to perform the following steps:

[0066] The first step is to determine the posture information of the above-mentioned visual sensor based on the stored target sampling area image information. The above-mentioned posture information can represent the posture vector of the above-mentioned visual sensor relative to the origin of the reference coordinate system during the sampling process. In practice, the above-mentioned processor can obtain the above-mentioned posture information based on the above-mentioned target sampling area image information through the PnP algorithm. The stored target sampling area image information can represent the image of the nasopharyngeal adenoids sampling area segmented from the infrared image information of the user taken. The above-mentioned nasopharyngeal adenoids sampling area can represent the area where the nasopharyngeal adenoids are located. The captured infrared image information can represent the infrared image of the user's nasopharyngeal adenoids collected by the above-mentioned infrared thermal imaging sensor.

[0067] The second step is to determine the posture difference information between the posture information and the preset posture information in response to determining that the posture information does not meet the preset posture setting condition. The preset posture setting condition can represent that the difference between the posture information and the preset posture information is less than the preset difference. Here, there is no limitation on the specific value of the preset difference, and the condition can be set according to actual needs. The preset posture information can represent the posture vector relative to the origin of the reference coordinate system that is preset during the sampling process of the visual sensor. The posture difference information can represent the difference between the vector represented by the posture information and the vector represented by the preset posture information. In practice, the processor can determine the posture difference information by the vector difference formula and the angle difference method.

[0068] Step 3: In response to determining that the posture difference information satisfies a preset playback condition, the audio playback component is controlled to play movement prompt information based on the posture difference information. The movement prompt information can be represented by a voice navigation instruction generated by converting the posture difference information. For example, the posture difference information can be the difference ΔX / ΔY / ΔZ of the three axes X / Y / Z, and the movement prompt information can be: "Move down." The preset playback condition can be that the difference represented by the detected posture difference information is greater than a preset threshold. The specific value of the preset threshold is not limited here. In practice, the processor can determine the movement prompt information corresponding to the posture difference information from a preset target movement prompt information set. The target movement prompt information in the preset target movement prompt information set can represent the correspondence between the posture difference information and the movement prompt information. For example, the target movement prompt information can be: "Position difference information: ΔX is greater than 5mm, movement prompt information: move left."

[0069] In a fourth step, in response to determining that the posture difference information satisfies the preset posture setting conditions, a sampling start prompt message corresponding to the nasopharyngeal adenoid collector is generated. The sampling start prompt message may represent an instruction prompting the operator to press the bottom of the base to perform sampling. For example, the sampling start prompt message may include: "When the deviation value ΔX / ΔY / ΔZ is ≤ ±0.5mm, generate "Posture is correct, please press the handle to perform sampling."

[0070] Step 5: In response to detecting the sample collection information of the net bag sampling structure after sampling captured by the visual sensor, determining whether the sample collection information meets a preset sample collection condition. The sample collection information may represent the outline features of the net bag after sampling. The outline features may represent the outline of the net bag within the sample collection information. The preset sample collection condition may be that the outline features in the sample collection information are identical to those in a standard sample library. In practice, the processor may perform image preprocessing on the image of the net bag after sampling using a Gaussian filter. The processor may then use a Canny operator to identify the outline of the net bag in the sample collection information. Thereafter, a pre-trained convolutional neural network (ResNet) may be used to compare the outline features with a standard sample library. Finally, in response to determining that the outline features are successfully compared with the standard sample library, determining that the sample collection information meets the preset sample collection condition. In response to determining that the outline features are unsuccessfully compared with the standard sample library, determining that the sample collection information does not meet the preset sample collection condition. The standard sample library may include outline features of net bags that have passed sampling.

[0071] The sixth step is to receive the mucus collection information of the brush sampling head after sampling captured by the visual sensor, wherein the mucus collection information may represent the image of the brush sampling head after sampling captured by the visual sensor.

[0072] Step 7: Determine mucus coverage information and mucus depth information based on the mucus collection information. The mucus coverage information can represent the coverage of the mucus layer collected by the brush sampling head after sampling. The mucus depth information can represent the three-dimensional physical thickness of the mucus layer collected by the brush sampling head after sampling. The mucus layer can represent the collected mucus on the surface of the adenoids. In practice, the processor can first process the mucus coverage image information through semantic segmentation to obtain the coverage of the mucus layer. Then, the mucus collection information can be processed using a multispectral reflectance model and the reflective ceramic markers to obtain the three-dimensional physical thickness of the mucus layer.

[0073] Step 8: Generate sample collection volume information based on the mucus coverage information and the mucus depth information. The sample collection volume information may represent the total amount of adenoid secretions collected based on the mucus coverage information and the mucus depth information. In practice, the processor may process the mucus coverage information and the mucus depth information using a spatial weighting function to obtain the sample collection volume information.

[0074] In the ninth step, in response to determining that the sample collection volume information satisfies the preset collection volume condition, the audio output module is controlled to play the sampling termination prompt information. The sampling termination prompt information may represent information indicating that the collected sample volume has met the standard. The preset collection volume condition may be that the collection volume represented by the sample collection volume information is greater than the preset collection volume. Here, there is no limitation on the specific numerical value of the preset collection volume, and it can be adjusted according to actual conditions. For example, the preset collection volume may be 10 μL. For example, the sample termination prompt information may represent: "Sample collection meets the standard."

[0075] The above technical solution, as an inventive point of an embodiment of the present disclosure, solves the third technical problem: "The sampling position is difficult to judge, and there is a high possibility of collecting invalid samples or causing great damage to the nasal tissue; and after the sampling is completed, it is found that the collected sample volume does not meet the standard and needs to be sampled again, resulting in cumbersome sampling operations and low sampling efficiency." The reasons for the great damage to the nasal tissue, cumbersome sampling operations and low sampling efficiency are as follows: In a home scenario, when the user is sampling, due to the unclear sampling position, it is easy to misjudge the sampling position and collect invalid samples, and easily cause damage to the nasal tissue; since it is impossible to judge whether the collected sample volume meets the standard during the sampling process, the user usually finds that the collected sample volume does not meet the standard after the sampling is completed and cannot obtain a valid sampling result, and needs to sample again, resulting in cumbersome sampling operations and long sampling time. If the above factors are solved, the effect of simplifying the sampling operation can be achieved. In order to achieve this effect, the nasopharyngeal adenoid collector disclosed in the present invention first uses the above-mentioned processor to determine the posture difference information between the above-mentioned posture information and the preset posture information. In response to determining that the above-mentioned posture difference information meets the preset playback condition, the above-mentioned processor then controls the above-mentioned audio playback component to play the movement prompt information based on the above-mentioned posture difference information. In response to determining that the above-mentioned posture information meets the above-mentioned preset posture setting condition, the above-mentioned processor generates a sampling start prompt information corresponding to the above-mentioned nasopharyngeal adenoid collector. In this way, the user can improve the accuracy of judging the sampling position through voice prompts, thereby reducing the difficulty of sampling. Afterwards, in response to detecting the sample collection information of the above-mentioned brush sampling head captured by the above-mentioned visual sensor, the above-mentioned processor determines whether the above-mentioned sample collection information meets the preset sample collection condition. In response to determining that the above-mentioned sample collection amount information meets the preset collection amount condition, the processor controls the above-mentioned audio output module to play the sampling termination prompt information. In this way, the user can complete the assessment of whether the collected sample amount meets the standard during the sampling stage, thereby reducing the need for repeated sampling and simplifying the sampling operation.

[0076] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through a nasopharyngeal adenoid collector according to some embodiments of the present disclosure, the sampling steps can be simplified, thereby shortening the sampling time, reducing the contamination of the sample in the nasal cavity and the contamination of the sample in the air, and improving the user experience. The reasons why the existing technology has many sampling steps, long sampling time, many cases of sample contamination in the nasal cavity and the contamination of the sample in the air, and poor user experience are: when using a swab for sampling, since it only includes a single swab rod and a single sampling head, only cell samples or secretion samples can be collected at a time; the rigid swab rod is easy to damage the nasal mucosa during the sampling process, resulting in a poor user experience and sample contamination; the swab rod needs to be broken to obtain the sample, resulting in many sampling steps and a long sampling time; the swab rod is easily contaminated with nasal contaminants during the process of entering and exiting the nasal cavity during sampling; and after the sampling is completed, when the swab rod's easy-to-break point is placed against the tube mouth and force is applied to break the swab rod from the easy-to-break point, the sampling head is exposed to the air for a long time, causing sample contamination. Based on this, some embodiments of the nasopharyngeal adenoid collector disclosed herein are characterized in that the nasopharyngeal adenoid collector includes an inner sampling structure, a middle sampling structure and an outer protective structure, wherein the inner sampling structure includes a metal wire, a base and a brush sampling head, wherein the head end of the metal wire is connected to the brush sampling head, and the tail end of the metal wire is connected to the base; the middle sampling structure includes a metal tube, a middle tube seat and a net bag sampling structure, wherein the head end of the metal tube is connected to the net bag sampling structure, and the tail end of the metal tube is connected to the middle tube seat; the outer protective structure includes an outer tube seat and a sheath tube, wherein the outer tube seat is connected to the tail end of the sheath tube, and the outer protective structure is used The inner sampling structure is embedded in the middle sampling structure, which is embedded in the outer protective structure. The inner and middle sampling structures are connected, and the front end of the sheath is provided with an arc-shaped protective edge. The inner and middle sampling structures can rotate independently for sampling. When in use, the base is pressed to squeeze the drive structure provided between the middle sampling structure and the outer protective structure, causing the brush sampling head and the net sampling structure to pop out. The base is rotated to engage the middle tube holder with the circumferential groove provided in the outer tube holder, allowing sampling to be performed through the brush sampling head and the net sampling structure. Because the inner and middle sampling structures of the nasopharyngeal adenoid collector can rotate synchronously during a single sampling operation to capture mucus secretions and desquamated epithelial cells on the surface of the adenoids, the sampling process can be simplified, the sampling time can be shortened, and the number of sampling times can be reduced.Because the inner sampling structure and the middle sampling structure are located inside the outer protective structure, they can provide protection for the inner sampling structure and the middle sampling structure when entering and exiting the nasal cavity, thereby reducing the sampling head from being contaminated by pollutants in the nasal passage and the exposure of the sample to air pollution after sampling. The arc-shaped contour design of the arc-shaped protective edge also reduces damage to the nasal mucosa. As a result, the sampling steps can be simplified, thereby shortening the sampling time, reducing the contamination of the sample in the nasal cavity and the contamination of the sample in the air, and improving the user experience.
