Description

Technical Field

[0001] Embodiments disclosed herein relate to the field of medical devices, specifically to nasopharyngeal adenoid collectors. Background Technology

[0002] A nasopharyngeal adenoid sampler can be used to sample adenoid tissue to provide a sample of the adenoids. Currently, existing nasopharyngeal adenoid samplers consist of only a single swab and a single sampling tip fixed to its front end, and the nasopharyngeal adenoid sampler is not detachable.

[0003] However, in practice, the following technical problems are frequently encountered when using a nasopharyngeal adenoid sampler:

[0004] When using swabs for sampling, the use of only a single swab and a single sampling tip means that only cell or secretion samples can be collected at a time. The rigid swab is prone to damaging the nasal mucosa during sampling, resulting in a poor user experience and sample contamination. Furthermore, the need to break the swab to obtain the sample adds multiple sampling steps, leading to a longer sampling time. During the sampling process, the swab is easily contaminated with nasal pollutants. After sampling, when the swab is broken by pressing the easy-break point against the tube opening, the sampling tip is exposed to air for a longer period, causing sample contamination.

[0020] The various embodiments disclosed above have the following beneficial effects: A nasopharyngeal adenoid collector according to some embodiments of this disclosure simplifies the sampling process, thereby shortening sampling time, reducing sample contamination within the nasal cavity and in the air, and improving the user experience. The reasons for the numerous sampling steps, long sampling time, frequent sample contamination within the nasal cavity and in the air, and poor user experience in the prior art are as follows: When using a swab for sampling, since it only includes a single swab rod and a single sampling tip, only cell or secretion samples can be collected at a time; the rigid swab rod is prone to damaging the nasal mucosa during sampling, resulting in a poor user experience and sample contamination; and the need to break the swab rod to obtain the sample results in numerous sampling steps and a long sampling time; the swab rod is easily contaminated with nasal pollutants during entry and exit from the nasal cavity; and after sampling, when the swab rod is broken from the breakable point by pressing against the tube opening, the sampling tip is exposed to air for a long time, causing sample contamination. Based on this, some embodiments of the nasopharyngeal adenoid collection device disclosed herein are characterized in that the nasopharyngeal adenoid collection device 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 first 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 mesh sampling structure, wherein the first end of the metal tube is connected to the mesh 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, wherein the outer tube seat is connected to the tail end of the sheath, and the outer protective structure is used for... The above-mentioned net sampling structure and brush sampling head are protected. 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. The front end of the sheath has an arc-shaped protective edge. The inner and middle sampling structures can rotate independently for sampling. In use, pressing the base squeezes the drive structure between the middle sampling structure and the outer protective structure, causing the brush sampling head and net sampling structure to pop out. Rotating the base causes the middle tube seat to engage with the circumferential groove in the outer tube seat, and sampling is performed through the brush sampling head and net sampling structure. Because the inner and middle sampling structures of the nasopharyngeal adenoid collector can rotate synchronously in a single sampling operation to capture mucus secretions and exfoliated epithelial cells on the surface of the adenoids, the sampling steps can be simplified, the sampling time shortened, and the number of samplings reduced.Furthermore, because the aforementioned inner and middle sampling structures are located within the outer protective structure, they are protected when entering and exiting the nasal cavity. This reduces the likelihood of the sampling head becoming contaminated with pollutants within the nasal passage and the sample being exposed to airborne contamination. The arc-shaped contour design of the protective edge also minimizes damage to the nasal mucosa. Consequently, the sampling process is simplified, resulting in shorter sampling time, reduced sample contamination within the nasal cavity and in the air, and an improved user experience.

[0053] In the process of adopting technical solutions to address the aforementioned technical problems, the following technical problem two often arises: When users perform nasopharyngeal adenoid sampling on children, the children are prone to discomfort and movement during the sampling process, which can easily cause damage to the children's nasal tissues, resulting in a high risk of sampling. Furthermore, multiple samplings are required for children, making sampling difficult and time-consuming. The lack of pre-sampling structure testing can lead to damage to the nasopharyngeal adenoids and contamination of the collected samples, necessitating multiple samplings. The conventional solution to this technical problem two is generally to use only the bent nasal swab's swab for sampling. However, considering the drawbacks of using only the bent nasal swab's swab for sampling, and leveraging the advantages of the inventor's company in the development of nasopharyngeal adenoid sampler structures, we have decided to adopt the following solution:

[0054] Optionally, the aforementioned outer protective structure may further include reflective ceramic markers, 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, which can be sleeved onto the outer protective component. The visual sensor may be fixed to the inside 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 seat 7 of the outer protective structure. The infrared thermal imaging sensor may be integrated at the front opening of the sheath 8. The resistance strain gauge may be adhered to the surface of the spring. The reflective ceramic markers 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 for processing 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 communicatively connected to the visual sensor, the audio playback component, the infrared thermal imaging sensor, and the resistance strain gauge. The aforementioned 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 aforementioned communication connections can include, but are not limited to, 3G / 4G connections, WiFi connections, Bluetooth connections, WiMAX connections, Zigbee connections, UWB (ultra-wideband) connections, and other currently known or future development communication methods. The aforementioned strain gauge can be a device that senses the voltage signal emitted by the user pressing the base. The aforementioned visual sensor can be a miniature camera.

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

[0056] The first step, in response to the detection that the voltage signal from the aforementioned resistance strain gauge meets the preset sampling start condition, is to execute the following steps:

[0057] The first sub-execution step involves receiving the sampling head image information of the brush sampling head and the net image information of the net bag acquired by the aforementioned vision sensor. The sampling head image information represents the image of the brush sampling head before sampling. The net image information represents the image of the net bag before sampling. The preset sampling start condition can be that the voltage signal of the resistance strain gauge is detected to be greater than 1.2V.

[0058] The second sub-execution step involves determining, based on the sampling head image information and the net image information, whether the middle layer sampling structure and the inner layer sampling structure meet preset replacement conditions. These preset replacement conditions can be detection result information corresponding to the sampling head image information or the net image information, indicating a failed detection. In practice, firstly, the processor can use the YOLOv7 model to detect the sampling head image information and the net image information, obtaining detection result information corresponding to the sampling head image information and the net image information. The obtained detection result information can indicate whether the detection is successful or unsuccessful. Then, in response to determining that the detection result information indicates a failed detection, it is determined that the middle layer sampling structure and the inner layer sampling structure meet the preset replacement conditions. Finally, in response to determining that the detection result information indicates a successful detection, it is determined that the middle layer sampling structure and the inner layer sampling structure do not meet the preset replacement conditions.

[0059] The third sub-execution step, in response to determining that the aforementioned brush sampling head or the aforementioned net bag meets the aforementioned preset replacement conditions, controls the aforementioned audio playback component to play the sampling structure replacement information. The aforementioned audio playback component can be a speaker used to play the aforementioned sampling structure replacement information. Here, the specific type of audio playback component is not limited. The aforementioned sampling structure replacement information can represent a message prompting 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-execution step, in response to determining that the aforementioned brush sampling head or the aforementioned net does not meet the aforementioned preset replacement conditions, involves receiving infrared image information acquired by the aforementioned infrared thermal imaging sensor. This infrared image information can characterize the infrared image of the user's nasopharyngeal adenoids acquired by the aforementioned infrared thermal imaging sensor. The aforementioned infrared thermal imaging sensor can be used to generate an infrared image of the nasopharyngeal adenoids by absorbing infrared radiation from the nasopharyngeal adenoids. Here, the specific type of the aforementioned infrared thermal imaging sensor is not limited.

[0061] The fifth sub-execution step involves determining the sampling area information corresponding to the nasopharyngeal adenoid collector based on the aforementioned infrared image information. This sampling area information characterizes the sampling area of ​​the nasopharyngeal adenoids in the aforementioned infrared image information. In practice, the processor can identify the area where the nasopharyngeal adenoids are located in the aforementioned infrared image information using edge detection.

[0062] The sixth sub-execution step involves segmenting the infrared image information based on the aforementioned sampling region information to obtain target sampling region image information corresponding to the aforementioned sampling region information. The target sampling region image information represents the image segmented from the aforementioned infrared image information corresponding to the aforementioned sampling region information. In practice, the processor can use an adaptive threshold segmentation algorithm to segment the infrared image information based on the aforementioned sampling region information to obtain the target sampling region image information.

[0063] The above-described technical solution, as an inventive point of this disclosure, solves technical problem two: "Sampling children is highly dangerous, difficult, and time-consuming; damaged sampling structures can easily damage the nasopharyngeal adenoids and contaminate the collected samples, thus requiring multiple samplings." The reasons for the low safety are as follows: When users sample children's nasopharyngeal adenoids, the children are prone to discomfort and movement during the sampling process, which can easily cause damage to the children's nasal tissues, resulting in a high risk of sampling and requiring multiple samplings, making sampling difficult and time-consuming; failure to inspect the sampling structure before sampling can lead to damaged sampling structures damaging the nasopharyngeal adenoids and contaminating the collected samples, thus requiring multiple samplings. Solving these factors can reduce the risk of sampling children; and during the sampling process, reduce the difficulty of sampling children, shorten sampling time, and reduce the likelihood of contaminated samples requiring multiple samplings. To achieve this effect, the outer protective structure of this disclosure may further include reflective ceramic markers, a protective film, a visual sensor, a processor, an audio playback component, an infrared thermal imaging sensor, and a resistance strain gauge. The aforementioned protective film can be a disposable polyethylene film, which can be fitted onto the outer protective component. This protective film reduces friction between the rigid swab and the nasal mucosa, and also reduces the invasiveness of the rigid swab, improving the child's experience during sampling and reducing harm caused by the child's discomfort and movement, thus lowering the risk of sampling. Furthermore, the reflective ceramic markers can increase the brightness within the nasal cavity, facilitating the location of the nasopharyngeal adenoids and improving the clarity of the captured image, thereby increasing the accuracy of locating the adenoids and reducing the difficulty of sampling. The processor can respond to determining that the brush sampling head or the net bag meets the preset replacement conditions by controlling the audio playback component to play sampling structure replacement information. Users can use the voice-played sampling structure replacement information to promptly replace damaged brush sampling heads or net bags. This reduces the risk of damage to the nasopharyngeal adenoids due to the failure to inspect the sampling structure before sampling, thus improving the accuracy of determining the sampling area and reducing the likelihood of sampling failures. It also reduces the difficulty of sampling children and shortens the sampling time.

[0064] In the process of adopting technical solutions to address the aforementioned technical problems, the following technical problem three often arises: In home scenarios, when users are sampling, the lack of clarity regarding the sampling location can easily lead to misjudgment of the sampling location, resulting in invalid samples and potential damage to nasal tissue. Furthermore, because it is impossible to determine whether the sample volume is sufficient during the sampling process, users often find that the sample volume is insufficient and effective sampling results cannot be obtained after sampling, requiring resampling, which makes the sampling operation cumbersome and time-consuming. The conventional solution to this technical problem three is generally to sample by referring to images of the nasopharyngeal adenoids. However, considering the drawbacks of sampling by referring to images of the nasopharyngeal adenoids and leveraging the advantages of the inventor's company in developing nasopharyngeal swab samplers, we have decided to adopt the following solution:

[0065] Alternatively, the processor described above can also be configured to perform the following steps:

[0066] The first step is to determine the pose information of the aforementioned visual sensor based on the stored target sampling region image information. This pose information represents the pose vector of the visual sensor relative to the origin of the reference coordinate system during the sampling process. In practice, the processor can obtain the pose information based on the target sampling region image information using the PnP algorithm. The stored target sampling region image information represents the image of the nasopharyngeal adenoids sampling region segmented from the captured infrared image information of the user. This nasopharyngeal adenoids sampling region represents the area where the nasopharyngeal adenoids are located. The captured infrared image information represents the infrared image of the user's nasopharyngeal adenoids acquired by the aforementioned infrared thermal imaging sensor.

[0067] The second step involves determining the pose difference information between the aforementioned pose information and the preset pose information in response to the determination that the pose information does not meet the preset pose setting conditions. The preset pose setting conditions can be defined as the difference between the aforementioned pose information and the preset pose information being less than a preset difference. Here, the specific value of the preset difference is not limited and can be determined according to actual needs. The preset pose information can be defined as the pose vector of the visual sensor relative to the origin of the reference coordinate system, preset during the sampling process. The pose difference information can be defined as the difference between the vector represented by the aforementioned pose information and the vector represented by the preset pose information. In practice, the processor can determine the pose difference information using vector difference formulas and angle difference methods.

[0068] Step 3: In response to determining that the pose difference information meets the preset playback conditions, the audio playback component is controlled to play motion prompt information based on the pose difference information. The motion prompt information can be represented as a voice navigation command generated from the pose difference information. For example, if the pose difference information is the difference between the X / Y / Z axes (ΔX / ΔY / ΔZ), then the motion prompt information could be: "Move downwards". The preset playback conditions can be that the difference represented by the detected pose difference information is greater than a preset threshold. Here, the specific value of the preset threshold is not limited. In practice, the processor can determine the motion prompt information corresponding to the pose difference information from a preset set of target motion prompt information. The target motion prompt information in the preset set of target motion prompt information can represent the correspondence between the pose difference information and the motion prompt information. For example, the target motion prompt information could be: "Pose difference information: ΔX greater than 5mm, motion prompt information: Move to the left".

[0069] Fourth, in response to the determination that the above-mentioned pose difference information meets the above-mentioned preset pose setting conditions, a sampling start prompt message corresponding to the above-mentioned nasopharyngeal adenoid collector is generated. The above-mentioned sampling start prompt message can represent an instruction to the operator to press the bottom of the above-mentioned base to perform sampling. For example, the sampling start prompt message can be: "When the above-mentioned deviation value ΔX / ΔY / ΔZ≤±0.5mm, generate "Position correct, please press the handle to sample".

[0070] Fifth step: In response to detecting the sample acquisition information of the sampled net structure captured by the aforementioned visual sensor, determine whether the sample acquisition information meets the preset sample acquisition conditions. The sample acquisition information can characterize the contour features of the sampled net. The contour features can characterize the contour of the net within the sample acquisition information. The preset sample acquisition conditions can be that the contour features in the sample acquisition information are the same as the contour features in a standard sample library. In practice, the processor can perform image preprocessing on the image of the sampled net using Gaussian filtering. Then, the processor can identify the contour of the net in the sample acquisition information using the Canny operator. Afterwards, a pre-trained convolutional neural network (ResNet) can be used to compare the contour features with the standard sample library. Finally, in response to determining that the contour features successfully compare with the standard sample library, determine that the sample acquisition information meets the preset sample acquisition conditions. In response to determining that the contour features fail to successfully compare with the standard sample library, determine that the sample acquisition information does not meet the preset sample acquisition conditions. The standard sample library can include the contour features of nets that have been sampled successfully.

[0071] The sixth step involves receiving the sampled mucus collection information from the brush sampling head captured by the aforementioned visual sensor. This mucus collection information can characterize the image of the brush sampling head captured by the aforementioned visual sensor.

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

[0073] Step 8: Based on the aforementioned mucus coverage and depth information, generate sample collection volume information. This sample collection volume information characterizes the total amount of adenoid secretions collected based on the mucus coverage and depth information. In practice, the processor can process the mucus coverage and depth information using a spatial weighting function to obtain the sample collection volume information.

[0074] Step nine: In response to determining that the sample collection volume information meets the preset collection volume condition, control the audio output module to play a sampling termination prompt message. This sampling termination prompt message indicates that the collected sample volume has met the standard. The preset collection volume condition can be that the collection volume indicated by the sample collection volume information is greater than a preset collection volume. Here, the specific value of the preset collection volume is not limited and can be adjusted according to actual conditions. For example, the preset collection volume can be 10 μL. For example, the sample termination prompt message can indicate: "Sample collection met the standard."

[0075] The above-described technical solution, as an inventive point of this disclosure, solves technical problem three: "The sampling location is difficult to determine, leading to a high probability of collecting invalid samples or causing significant damage to nasal tissue; and after sampling, if the sample volume is found to be insufficient, resampling is required, resulting in cumbersome sampling operations and low sampling efficiency." The reasons for the high damage to nasal tissue, cumbersome sampling operations, and low sampling efficiency are as follows: In home settings, users are prone to misjudging the sampling location and collecting invalid samples due to uncertainty about the sampling location, which can easily damage nasal tissue. Furthermore, because it is impossible to determine whether the sample volume is sufficient during sampling, users often find that the sample volume is insufficient after sampling, resulting in ineffective sampling results and requiring resampling, leading to cumbersome sampling operations and long sampling times. Solving these factors simplifies the sampling process. To achieve this effect, the nasopharyngeal adenoid sampler disclosed herein first uses the processor to determine the pose difference information between the pose information and the preset pose information. In response to determining that the pose difference information meets the preset playback conditions, the processor then controls the audio playback component to play movement prompt information based on the pose difference information. In response to determining that the pose information meets the preset pose setting conditions, the processor generates a sampling start prompt message corresponding to the nasopharyngeal adenoid sampler. Thus, users can improve the accuracy of judging the sampling position through voice prompts, thereby reducing the sampling difficulty. Subsequently, in response to detecting the sample acquisition information acquired by the visual sensor from the brush sampling head, the processor determines whether the sample acquisition information meets the preset sample acquisition conditions. In response to determining that the sample acquisition quantity information meets the preset acquisition quantity conditions, the processor controls the audio output module to play a sampling termination prompt message. Thus, users can complete the evaluation of whether the sample acquisition quantity meets the standard during the sampling stage, reducing the need for repeated sampling and simplifying the sampling operation.

[0076] The various embodiments disclosed above have the following beneficial effects: A nasopharyngeal adenoid collector according to some embodiments of this disclosure simplifies the sampling process, thereby shortening sampling time, reducing sample contamination within the nasal cavity and in the air, and improving the user experience. The reasons for the numerous sampling steps, long sampling time, frequent sample contamination within the nasal cavity and in the air, and poor user experience in the prior art are as follows: When using a swab for sampling, since it only includes a single swab rod and a single sampling tip, only cell or secretion samples can be collected at a time; the rigid swab rod is prone to damaging the nasal mucosa during sampling, resulting in a poor user experience and sample contamination; and the need to break the swab rod to obtain the sample results in numerous sampling steps and a long sampling time; the swab rod is easily contaminated with nasal pollutants during entry and exit from the nasal cavity; and after sampling, when the swab rod is broken from the breakable point by pressing against the tube opening, the sampling tip is exposed to air for a long time, causing sample contamination. Based on this, some embodiments of the nasopharyngeal adenoid collection device disclosed herein are characterized in that the nasopharyngeal adenoid collection device 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 first 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 mesh sampling structure, wherein the first end of the metal tube is connected to the mesh 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, wherein the outer tube seat is connected to the tail end of the sheath, and the outer protective structure is used for... The above-mentioned net sampling structure and brush sampling head are protected. 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. The front end of the sheath has an arc-shaped protective edge. The inner and middle sampling structures can rotate independently for sampling. In use, pressing the base squeezes the drive structure between the middle sampling structure and the outer protective structure, causing the brush sampling head and net sampling structure to pop out. Rotating the base causes the middle tube seat to engage with the circumferential groove in the outer tube seat, and sampling is performed through the brush sampling head and net sampling structure. Because the inner and middle sampling structures of the nasopharyngeal adenoid collector can rotate synchronously in a single sampling operation to capture mucus secretions and exfoliated epithelial cells on the surface of the adenoids, the sampling steps can be simplified, the sampling time shortened, and the number of samplings reduced.Furthermore, because the aforementioned inner and middle sampling structures are located within the outer protective structure, they are protected when entering and exiting the nasal cavity. This reduces the likelihood of the sampling head becoming contaminated with pollutants within the nasal passage and the sample being exposed to airborne contamination. The arc-shaped contour design of the protective edge also minimizes damage to the nasal mucosa. Consequently, the sampling process is simplified, resulting in shorter sampling time, reduced sample contamination within the nasal cavity and in the air, and an improved user experience.
