Abstract
Description
Technical Field
[0001] This application relates to the field of medical interaction, and in particular to a behavior management device and behavior management method for use in oral diagnosis and treatment. Background Technology
[0002] In dentistry, behavioral management primarily refers to controlling patients' pain and fear. For patients with dental phobia, effective behavioral management can alleviate their anxiety and improve their treatment experience, leading to its increasingly widespread application in the field of dentistry. Common behavioral management methods include non-pharmacological therapies. These methods utilize appropriate language, gentle physical gestures, and necessary companionship to alleviate patients' anxiety and fear of dental treatment.
[0003] Nitrous oxide-oxygen inhalation sedation. The patient is relaxed by inhaling a nitrous oxide-oxygen mixture, allowing oral treatment to be performed while the patient is in a relaxed state.
[0004] Oral sedation. Commonly used in children. Oral treatment is performed after oral sedation.
[0005] Intravenous sedation. Sedative drugs are administered intravenously to induce a sedative state in the patient for oral treatments, such as complex tooth extractions and dental implant procedures. Examples include midazolam and remimazolam.
[0006] Local anesthesia techniques. Pain caused by oral procedures is controlled through methods such as topical anesthesia, infiltration anesthesia, and nerve block anesthesia. Medications used include tetracaine, procaine, lidocaine, articaine, and mepivacaine.
[0007] Due to the limitations of the dental operating environment and the precision required for the procedures, patient cooperation is crucial during dental treatment. In some high-speed dental procedures, patients often need to keep their heads still; otherwise, the precision of the treatment will be affected, and adverse consequences such as soft tissue abrasions may occur. Because of this characteristic, commonly used non-pharmacological treatments such as massage, infrared therapy, and electromagnetic therapy are difficult to implement during dental treatment.
[0008] Drug sedation techniques are widely used in dentistry. However, during dental procedures, dentists operate continuously within the mouth, potentially introducing contaminants such as water, droplets, and blood, which can affect airway safety. If the patient remains conscious and has an active cough reflex, the procedure is relatively safe. Furthermore, maintaining patient consciousness facilitates cooperation with the dentist during treatment. Deep sedation can lead to insufficient spontaneous ventilation, necessitating airway intervention. Deep sedation using methods such as nitrous oxide-oxygen inhalation, oral sedatives, or intravenous sedation may result in insufficient spontaneous ventilation.
[0009] In conclusion, there is a need for a behavior management device that can safely control patients' pain and fear and monitor their sedation levels. Summary of the Invention

[0012] Secondly, this application provides a behavior management method for oral diagnosis and treatment, applied to the aforementioned behavior management device for oral diagnosis and treatment, wherein the behavior management method for oral diagnosis and treatment includes: acquiring the patient's corresponding reference current level.
[0013] In physiotherapy mode, the electrical stimulation transmitting module is controlled to transmit transcutaneous electrical stimulation to the electrode pads at a set frequency and the corresponding reference current level for the patient.
[0014] In sedation monitoring mode, images of the patient's face and hands are acquired.
[0015] The patient's facial and hand images are recognized to obtain facial recognition results and hand recognition results; the facial recognition results are the patient's facial expressions; the hand recognition results are the patient's hand movements or the hands cannot be recognized.

[0017] According to the specific embodiments provided in this application, this application has the following technical effects: This application provides a behavior management device and method for oral treatment. Certain acupoints help relieve pain, including toothache, headache, and nausea and vomiting caused by anxiety. Neiguan acupoint is such an acupoint. In this application, the electrode pad is placed at Neiguan acupoint, avoiding the situation where patients cannot keep their heads still during oral treatment due to commonly used non-pharmacological treatments.

[0022] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] In one exemplary embodiment, such as Figure 1As shown, a behavior management device for oral diagnosis and treatment is provided, comprising: a main unit and electrode pads; the electrode pads are placed on the Neiguan acupoint of the patient, and the electrode pads are used to stimulate the Neiguan acupoint; the main unit includes a controller and an image recognition module and an electrical stimulation emission module, both connected to the controller; the electrical stimulation emission module is connected to the electrode pads; the controller includes: a physiotherapy stimulation module and a sedation monitoring stimulation module, the physiotherapy stimulation module is used to control the electrical stimulation emission module to emit transcutaneous electrical stimulation to the electrode pads at a set frequency and a reference current level corresponding to the patient in physiotherapy mode; the image recognition module is used to recognize the patient's facial image and hand image to obtain facial recognition result and hand recognition result; the facial recognition result is the patient's facial expression; the hand recognition result is the patient's hand movement or the hand cannot be recognized; the sedation monitoring stimulation module is used to control the electrical stimulation emission module to emit transcutaneous electrical stimulation to the electrode pads in sedation monitoring mode and determine the patient's sedation level based on the facial recognition result or the hand recognition result.
[0024] In practical applications, the two electrode pads are connected to the electrical stimulation transmitting module by wires and are attached to the Neiguan acupoint on the patient's wrist to provide intermittent electrical stimulation to the patient based on the electrical stimulation signal transmitted by the electrical stimulation transmitting module.
[0025] In another exemplary embodiment of this application, the controller further includes a baseline measurement module for acquiring the patient's reference current level.
[0026] In another exemplary embodiment of this application, the behavior management device for oral treatment further includes: a display connected to the controller, through which a physiotherapy mode, a sedation monitoring mode, or a baseline measurement mode can be selected by the doctor during treatment. The display is connected to the controller for the doctor to select a treatment mode during treatment.
[0027] In another exemplary embodiment of this application, the sedation monitoring stimulation module specifically includes: a safety level judgment unit, used to control the electrical stimulation emission module to emit transcutaneous electrical stimulation to the electrode pad at the target current level for the current stimulation number in sedation monitoring mode, and to determine whether the target current level for the current stimulation number reaches the preset safety level corresponding to the patient under the preset sedation level, and to obtain a first judgment result; the target current level for the current stimulation number is obtained by adding one level to the target current level for the previous stimulation number; the target current level for the initial stimulation number is the reference current level corresponding to the patient.
[0028] The first result unit is used to determine whether the patient is in an uncomfortable state based on the facial recognition result or the hand recognition result if the first judgment result is yes, and obtain a second judgment result; if the second judgment result is yes, determine that the patient is under a preset sedation level, and control the electrical stimulation transmitting module to transmit transcutaneous electrical stimulation to the electrode pad at a set frequency and the reference current level corresponding to the patient; if the second judgment result is no, determine that the patient is not under a preset sedation level, issue an alarm and control the electrical stimulation transmitting module to stop transmitting transcutaneous electrical stimulation.
[0029] The second result unit is used to determine whether the patient is in an uncomfortable state based on the facial recognition result or the hand recognition result if the first judgment result is negative, and to obtain a third judgment result; if the third judgment result is positive, it is determined that the patient is under a preset sedation level, and the electrical stimulation transmitting module is controlled to transmit transcutaneous electrical stimulation to the electrode pad at a set frequency and the reference current level corresponding to the patient; if the third judgment result is negative, it is determined that the patient is under a preset sedation level, and the electrical stimulation transmitting module is controlled to transmit transcutaneous electrical stimulation to the electrode pad at the target current level for the current stimulation number, until the next stimulation number is entered.
[0030] In practical applications, issuing an alarm specifically involves displaying a prominent red alarm symbol on the control screen.
[0031] In practical applications, the image recognition module uses one camera to capture facial images and another camera to capture hand images.
[0032] The facial recognition camera is a fixed-focus camera, mounted on the dental chair lamp, so that it is directly facing the patient's face as the lamp's angle is adjusted. Based on the lamp's focal length, the facial recognition camera's field of view is slightly larger than the patient's entire head.
[0033] The hand recognition camera is mounted on the left side of the dental chair via a floor-standing bracket, and its angle is adjusted to face the patient's left hand. The camera angle is adjustable; it is a zoom camera with a minimum field of view that encompasses the patient's entire left hand.
[0034] The image recognition module uses computer vision and machine learning algorithms to obtain facial recognition and hand recognition results.
[0035] Before the treatment starts, the facial recognition system begins to run. It processes the images captured by the face camera through a facial recognition model to obtain the facial recognition confidence RESULTS.DETECTIONS. Set the confidence threshold DETECTION_THRESHOLD = 0.65. When RESULTS.DETECTIONS > DETECTION_THRESHOLD, it is judged that a face is recognized. If the recognition is unsuccessful, adjust the camera angle and distance until the recognition is successful. Use a hand feature point detection model to recognize the images captured by the hand camera. After all the landmark points are recognized, all the landmark points appear on the display screen and the target recognition is successful, and the system can start running. If the target recognition is unsuccessful, further adjust the camera angle and distance until all the landmark points appear on the display screen and the target recognition is successful.
[0036] In practical applications, facial expressions include: eyes open, eyes half-open, eyes closed, and frowning. Hand movements include: open, half-fist, and fist. If no hand landmark points are recognized, it is determined that the target is lost, and the hand recognition result is that the hand cannot be recognized.
[0037] In practical applications, the facial recognition result is obtained by using computer vision and machine learning algorithms. Specifically: calculate the aspect ratio of the eyes EAR. If the aspect ratio of the eyes is less than 0.12, it is judged that the eyes are closed. If the aspect ratio of the eyes is greater than 0.2, it is judged that the eyes are open. If 0.12 ≤ EAR ≤ 0.2, it is judged that the eyes are half-open.
[0038] Calculate the aspect ratio of the eyebrows and the eye corners according to the formula BROW_POS_LOCATION_RATIO = ||B285 - B55|| / ||B417 - B285||. || || represents calculating the distance. B285 represents the point corresponding to the root of the left eyebrow, B55 represents the point corresponding to the root of the right eyebrow, ||B285 - B55|| represents calculating the distance between the two eyebrow roots, B417 represents the position corresponding to the inner corner of the left eye, and ||B417 - B285|| represents calculating the distance between the eye corner and the eyebrow root.
[0039] The threshold for frowning BROW_THRESHOLD = 0.45.
[0040] When BROW_POS_LOCATION_RATIO ≥ BROW_THRESHOLD, it is judged as frowning.
[0041] When BROW_POS_LOCATION_RATIO < BROW_THRESHOLD, it is judged as not frowning.
[0042] The MediaPipe Hands deep learning-based hand feature point detection method can detect 21 3D feature points of the hand in real time. These feature points include key parts such as the wrist and finger joints. Its core is to map the input hand image to feature point coordinates using a pre-trained neural network model (MediaPipe Hands model). During model training, a large number of hand images annotated with feature points are used as training data. By learning the mapping relationship between feature points and image pixels in this data, feature point detection of new input images is achieved. In practical applications, computer vision and machine learning algorithms are used to obtain hand recognition results. Specifically, let the input image be I, and the output of the hand feature point detection model, i.e., the MediaPipeHands model, is the feature point set Q = {q1, q2, ..., q21}, where each feature point qi is a 3D coordinate (xi, yi, zi). The model can be represented as: Where H() is the MediaPipe Hands model.
[0043] First, the input image I is normalized to fit the model input. The normalized image is then input into model H() to obtain the feature point set Q. The detected feature points are then smoothed to reduce noise and jitter.
[0044] The joint angle of each finger is calculated based on the set of feature points. An angle threshold β is set. When the joint angle of a finger is greater than the threshold, the finger is considered to be open.
[0045] Calculate the joint vector for each finger based on the set of feature points. and , This represents the vector from the base of the finger to the middle of the finger. Let represent the vector from the middle of the finger to the fingertip. For each finger, calculate the bending angle α of its interphalangeal joint. α can be expressed as: , | represents the calculation of the modulus. An angle threshold γ is set; when the bending angle of the interphalangeal joint of a finger is less than this threshold, the finger is considered bent. If the bending angle of all (or most) fingers is less than the threshold, and the fingertips are close to the wrist or palm, it is judged as a clenched fist.
[0046] In another exemplary embodiment of this application, the baseline measurement module includes: a response judgment unit, used to control the electrical stimulation emission module to emit transcutaneous electrical stimulation to the electrode pad at the target current level for the current measurement number, and to judge whether the patient's response has reached the preset stop condition; the target current level for the current measurement number is obtained by adding one level to the target current level for the previous measurement number.
[0047] The reference current range determination unit is used to determine the patient's reference current range based on the target current range for the current number of measurements if the patient's response meets the preset stop condition.
[0048] The measurement count update unit is used to update the measurement count and proceed to the next measurement if the patient's response does not meet the preset stop condition.
[0049] In another exemplary embodiment of this application, the reference current level determination unit specifically determines the target current level for the current measurement number as the patient's reference current level if the patient reports stimulation without discomfort.
[0050] If the patient is determined to be in an uncomfortable state based on facial recognition results, hand recognition results, or electrocardiogram monitoring results, then the target current level of the previous measurement is determined as the patient's reference current level.
[0051] The procedure for using the behavior management device provided in this application for oral diagnosis and treatment is as follows: 1. Place the electrode pads on the Neiguan acupoint on the patient's left wrist and determine the baseline level (reference current level) of electrical stimulation while the patient is awake.
[0052] Before starting the measurement, fully explain and communicate with the patient, instructing them to verbally indicate when there is stimulation without discomfort. When the patient experiences stimulation without discomfort, determine the current setting at that moment as the reference current setting. The reference current setting is determined based on the patient's subjective feedback.
[0053] At the start of the measurement, select the baseline measurement mode on the display. Electrical stimulation is manually controlled at this stage. Start with the first level, increasing the stimulation level gradually with intervals of at least 10 seconds. After the measurement begins, change the level without informing the patient. Simultaneously, the image recognition module monitors the patient's face and hands; the electrocardiogram (ECG) monitors vital signs such as heart rate, blood pressure, blood oxygen saturation, and respiratory rate. If the recognition result is: eyes open, brow furrowed, hands open, or hands not recognized, a prominent red warning sign appears on the display. Even without verbal notification, this is considered an indication of discomfort, and the baseline level is lowered. If the ECG monitor detects significant changes in vital signs such as heart rate, blood pressure, blood oxygen saturation, or respiratory rate, this is also considered an indication of discomfort. Even without verbal notification, the baseline level is lowered, and the reference current level is objectively determined by the instrument. The patient's baseline level is recorded in the controller. There are 30 levels in total, based on the electrical stimulation current. The first level is 0 microamps to 10 microamps, the second level is 10 microamps to 20 microamps, and so on. Each electrical stimulation is delivered for a fixed duration of 2 seconds, with a 10-second interval between each stimulation.
[0054] In a relaxed state, patients typically hold their hands in a semi-clenched fist at their sides. Patients with dental phobia, however, become tense as soon as they sit in the dental chair, and their hands may remain clenched. Therefore, depending on the individual patient, both clenched and semi-clenched fists correspond to the patient's baseline state. Before treatment begins, the dentist will communicate with the patient, instructing them to raise their left hand if they experience any discomfort during treatment. When the patient feels discomfort, they may open or raise their hand. Raising the hand may be outside the camera's field of view, thus failing to identify the hand's openness or discomfort. A convolutional neural network continuously learns and updates to adapt to hand movements under different lighting conditions.
[0055] 2. Select the physiotherapy mode on the monitor.
[0056] As is customary for most dentists, a doctor-patient consultation is held before treatment begins, instructing the patient to raise their left hand if they experience any discomfort during the procedure. To begin treatment, the patient clicks the start button on the monitor. The controller then begins to deliver intermittent electrical stimulation at the baseline setting (reference current setting) for when the patient is awake.
[0057] 3. During treatment, if the doctor needs to assess the patient's sedation status, they can select the sedation monitoring mode on the monitor at any time, choosing between mild, moderate, or conscious sedation as needed. Initially, the controller continuously and intermittently emits electrical stimulation at the baseline level. Subsequently, the intensity of electrical stimulation is gradually increased at specific time intervals from the baseline level. Simultaneously, the image recognition module monitors the face and hands. When the recognition result is: eyes open, brow furrowed, hands open, or no hands can be recognized, the signal is immediately transmitted back to the controller, which stops increasing the electrical stimulation intensity and returns to the baseline level for intermittent emission. At the same time, the text indicating "eyes open, brow furrowed, hands open, or no hands can be recognized" is displayed prominently on the screen. If the electrical stimulation level is increased to the safe level, and the image recognition module still does not indicate "eyes open, brow furrowed, hands open," or no hands can be recognized, an alarm is triggered, and a prominent red alarm symbol is displayed on the screen.
[0058] Mild sedation, moderate sedation, and conscious sedation each correspond to a safe level of electrical stimulation, calculated based on the patient's baseline level, treatment program, and sedation depth. The formula is: Safe level = Baseline level + a × Treatment program + b × Sedation depth + c × Weight. Where a, b, and c are coefficients.
[0059] The value for each treatment item is assigned based on the specific treatment, such as fillings for superficial or moderate caries, fillings for deep caries, root canal treatment, extraction of teeth in alignment, extraction of impacted teeth, scaling or root planing, and is divided into 0, 1, and 2. If the dentist does not select a treatment item, the default value is 0.
[0060] The sedation depth value is assigned based on the preset sedation level. Mild and moderate sedation are assigned a value of 1, and conscious sedation is assigned a value of 2.
[0061] The weight value is assigned according to different weight ranges.
[0062] This application proposes a behavior management device for use in oral diagnosis and treatment, which assists in behavior management during oral sedation, alleviates the patient's anxiety, and assists in the assessment of sedation status.
[0063] This application delivers transcutaneous electrical stimulation via electrode pads attached to the wrist, without interfering with the doctor's operation. It provides sedation and analgesia during oral treatment, safely controlling the patient's pain and fear.
[0064] Dental treatment typically takes a long time. This application utilizes the time spent on dental treatment to simultaneously perform electrical stimulation therapy. Through electrical stimulation therapy, the patient's attention is diverted, achieving the goal of behavioral management.
[0065] Current assessment indicators and equipment often focus on general anesthesia. There is a lack of objective evaluation equipment or indicators for assessing the degree of sedation in conscious sedation. This application uses the patient's response to transcutaneous electrical stimulation in sedation monitoring mode as an objective indicator for evaluating and distinguishing the degree of sedation. Using transcutaneous electrical stimulation as a means of judging the degree of sedation in conscious sedation fills a gap in this field, provides objective reference for clinical medical staff, and ensures patient safety.
[0066] This application also provides a behavior management method for oral diagnosis and treatment, applied to the aforementioned behavior management device for oral diagnosis and treatment, wherein the behavior management method for oral diagnosis and treatment includes: acquiring the patient's corresponding reference current level.
[0067] In physiotherapy mode, the electrical stimulation transmitting module is controlled to transmit transcutaneous electrical stimulation to the electrode pads at a set frequency and the corresponding reference current level for the patient.
[0068] In sedation monitoring mode, images of the patient's face and hands are acquired.
[0069] The patient's facial and hand images are recognized to obtain facial recognition results and hand recognition results; the facial recognition results are the patient's facial expressions; the hand recognition results are the patient's hand movements or the hands cannot be recognized.
[0070] The control electrical stimulation transmitting module emits transcutaneous electrical stimulation to the electrode pads and determines the patient's sedation level based on facial or hand recognition results.
[0071] In another exemplary embodiment of this application, obtaining the reference current level corresponding to the patient specifically includes: under the current number of measurements, controlling the electrical stimulation emission module to emit transcutaneous electrical stimulation to the electrode pad at the target current level under the current number of measurements, and determining whether the patient's response has reached the preset stop condition; the target current level under the current number of measurements is obtained by adding one level to the target current level under the previous number of measurements.
[0072] If the patient's response meets the preset stop condition, the target current level for the current measurement count is determined as the patient's reference current level.
[0073] If the patient's response does not meet the preset stop criteria, the measurement count will be updated, and the next measurement will begin.
[0074] In another exemplary embodiment of this application, controlling the electrical stimulation transmitting module to emit transcutaneous electrical stimulation to the electrode pads and determining the patient's sedation level based on facial recognition results or hand recognition results specifically includes: at the current stimulation count, controlling the electrical stimulation transmitting module to emit transcutaneous electrical stimulation to the electrode pads at the target current level for the current stimulation count, and determining whether the target current level for the current stimulation count reaches the preset safety level corresponding to the patient under the preset sedation level, thereby obtaining a first determination result; the target current level for the current stimulation count is obtained by adding one level to the target current level for the previous stimulation count; the target current level for the initial stimulation count is the reference current level corresponding to the patient.
[0075] If the first judgment result is yes, then the patient is judged to be in an uncomfortable state based on the facial recognition result or the hand recognition result, and a second judgment result is obtained.
[0076] If the second judgment result is yes, then it is determined that the patient is under the preset sedation level, and the electrical stimulation transmitting module is controlled to transmit transcutaneous electrical stimulation to the electrode pad at the set frequency and the reference current level corresponding to the patient.
[0077] If the second judgment result is negative, it is determined that the patient is not under the preset sedation level, and an alarm is issued and the electrical stimulation transmitting module is controlled to stop transmitting transcutaneous electrical stimulation.
[0078] If the first judgment result is negative, then the third judgment result is obtained by judging whether the patient is in an uncomfortable state based on the facial recognition result or the hand recognition result.
[0079] If the third judgment result is yes, then it is determined that the patient is under a preset sedation level, and the electrical stimulation transmitting module is controlled to transmit transcutaneous electrical stimulation to the electrode pads at a set frequency and the reference current level corresponding to the patient.
[0080] If the third judgment result is negative, then the patient is determined to be under a preset sedation level, and the electrical stimulation transmitting module is controlled to transmit transcutaneous electrical stimulation to the electrode pads at the target current level for the current stimulation count, until the next stimulation count begins.
[0081] In another exemplary embodiment of this application, if the patient's response reaches the preset stop condition, the target current level for the current measurement count is determined as the patient's reference current level. Specifically, if the patient indicates stimulation without discomfort, the target current level for the current measurement count is determined as the patient's reference current level.
[0082] If the patient is determined to be in an uncomfortable state based on facial recognition results, hand recognition results, or electrocardiogram monitoring results, then the target current level of the previous measurement is determined as the patient's reference current level.
[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
