Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an auxiliary airway opening system and method. Background Art

[0002] After intravenous anesthesia, the patient's muscles will relax and become limp, and the tongue in the mouth will also relax. If the patient is in a lying position, the root of the tongue will fall to the trachea, causing tracheal obstruction and the risk of suffocation. In these medical operations that require intravenous anesthesia, medical staff are usually required to lift the patient's mandible and push it in the opposite direction of the tongue root falling, so as to adjust the tongue root from blocking the trachea to a non-blocking trachea state to ensure that the patient can breathe normally. This operation method imposes a heavy workload on medical staff. When a single medical staff takes care of multiple patients, it is often difficult for medical staff to lift a single patient for a long time. There is a study on the effect of jaw lift operation on the success rate of respiratory mask placement in patients in the current evidence-based medicine database Trip Medical Database. In this evidence-based medicine evidence, 157 clinical trials were conducted. It includes a control group (n=73) and a test group (n=79). After the patient was induced with general anesthesia, the control group used the traditional method to insert a flexible laryngeal airway mask. The test group used the jaw lift method to assist in the placement of a flexible laryngeal airway mask. The success rate of flexible laryngeal airway mask insertion, alignment status, oropharyngeal leakage pressure (OLP) of the laryngeal mask, oropharyngeal soft tissue damage, postoperative pharyngeal pain, and the incidence of airway adverse events were recorded in the two groups.

[0003] The results showed that the first placement success rates of the flexible laryngeal mask in the control group and the experimental group were 73.8% and 97.5%, respectively, and the final success rates were 97.5% and 98.7%, respectively. Compared with the control group, the first placement success rate in the experimental group was higher, and the difference was statistically significant. There was no statistically significant difference in the final success rate between the two groups (P = 0.56). The alignment score showed that the placement of the experimental group was better than that of the control group, and the difference was statistically significant. The OLP of the control group was 22.1 ± 2.6 cmH 2 O, OLP of the experimental group was 25.4±3.8cmH 2 O. The OLP of the experimental group was significantly higher than that of the control group. The incidence of mucosal injury and postoperative pharyngitis in the experimental group was 2.5% and 5.0%, which was significantly lower than 23.0% and 16.7% in the control group. There were no adverse airway events in each group.

[0004] The conclusion is that the jaw lift method can improve the success rate of the first placement of the soft laryngeal mask and the positioning of the laryngeal mask, increase the sealing pressure of the laryngeal mask, and reduce the incidence of oropharyngeal soft tissue injury and postoperative pharyngeal pain. In other words, the jaw lift method is of great significance for the opening of the airway in patients undergoing general anesthesia.

[0005] Airway opening devices exist in the prior art, such as oropharyngeal airways and nasopharyngeal airways. However, the oropharyngeal airway is highly irritating and produces a lot of secretions, which is not suitable for gastroscopy. The nasopharyngeal airway is highly irritating, and the nasal mucosa is easily damaged and bleeding, which can easily cause the risk of aspiration.

[0006] The patent document with publication number CN109924964A discloses a method and system for preventing sleep apnea based on a chin rest, which belongs to the technical field of preventing sleep apnea. The method includes the following steps: S1: monitoring the user's breathing state by wearing a chin rest, the breathing state includes abnormal breathing and normal breathing, when the user has abnormal breathing, the chin rest enters the working mode S2; S2: adjusting the posture of the chin rest in the working mode, the posture adjustment is to push the chin rest partly upward and forward to increase the airway gap of the user, and at the same time perform S3 to monitor whether the user's breathing state has returned to normal; S3: when the user's breathing state has returned to normal, the local force state of the chin rest is detected, when the user's breathing state has not returned to normal, the posture adjustment of step S2 can continue. The method and system of this patent are used to solve the technical problems that the means of treating OSAHS in the prior art have many adverse reactions and insignificant therapeutic effects. However, the defects of this patent are:

[0007] 1. The mandibular support of the patent is an air bag or mechanical device that lifts the patient's entire mandible. This integral mandibular support has limited effect in opening the airway and cannot completely or partially replace the manual mandibular support. Especially in the case of respiratory obstruction during painless digestive endoscopy, the mandibular support of the patent cannot achieve the anterior-upward displacement of the mandibular angle.

[0008] 2. The chin support of the patent needs to be specially customized according to the patient's body shape. Otherwise, when patients of different body shapes wear the chin support, the required lifting distance is different and the effect is also different, which makes the patent only applicable to patients of a certain body shape and cannot provide targeted chin support for patients of different body shapes. In particular, the chin support of the patent cannot accurately adjust the position of the force application point of the patient's mandible and the force mode, resulting in different effects of opening the airway after the patient changes his body position.

[0009] 3. This patent does not adjust the force application point and force direction according to the change of body position of the patient after abnormal breathing, and it cannot meet the accurate force application point and force direction of the support module required to rescue patients with abnormal breathing.

[0010] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0011] There are devices in the prior art for lifting the patient's lower jaw, but the main idea of ​​the device is to open the patient's airway by lifting the patient's entire lower jaw. For patients who need to undergo painless digestive endoscopy, they are injected with anesthetics. The method of lifting the lower jaw as a whole is less efficient in opening the airway, and the device cannot accurately grasp the timing of lifting the mandibular angle, how to lift the mandibular angle after the patient's body position changes, and how to accurately lift the patient's mandibular angle. The present invention is mainly used in the process of painless digestive endoscopy of patients.

[0012] The prior art has already presented a technical solution for accurately monitoring the user's breathing state by wearing a chin support structure. For example, the patent document with publication number CN109924964A discloses a method and system for preventing sleep apnea based on a chin support, the method comprising: first, monitoring the user's breathing state by wearing a chin support, the breathing state includes abnormal breathing and normal breathing, when the user has abnormal breathing, the chin support enters the working mode; secondly, adjusting the posture of the chin support in the working mode, the posture adjustment is that the chin support is partially pushed upward and forward to increase the airway gap of the user, and at the same time monitoring whether the user's breathing state has returned to normal; finally, when the user's breathing state has returned to normal, the local force state of the chin support is detected, and when the user's breathing state has not returned to normal, the posture adjustment of the working mode step is continued. This technical solution can simultaneously realize the monitoring of the user's breathing state and the airway adjustment process under abnormal breathing state. However, this technical solution realizes the local pushing action of the chin support through a mechanical motion pushing unit or an airbag inflation pushing unit, thereby completing the posture adjustment action of the chin support. On the one hand, this setting can only adjust the user's mandibular posture through a single adjustment method, and cannot adjust multiple force parameters of the support module used to support the user's breathing state according to the user's different body positions and breathing states, thereby failing to achieve a refined adjustment process of the user's airway presentation state. On the other hand, the single-degree-of-freedom airway adjustment mechanism in this technical solution is significantly different from the multi-degree-of-freedom support module of the present invention, and cannot perform multi-parameter adjustment according to the user's actual breathing state.

[0013] In view of the shortcomings of the prior art, the present invention provides an auxiliary airway opening system, the system includes a support module for lifting the mandibular angle and forehead of a patient, a processing module located in the main frame of the support module or in a remote computer room server, and a monitoring module for monitoring the physiological parameters of the patient; the processing module communicatively connected to the support module is configured to: judge the patient's respiratory state and the corresponding patient position based on the physiological parameters monitored by the monitoring module; adjust the support scheme of the support module based on the patient's respiratory state, and adjust the position, size and direction of the force point of the support force applied by the support module according to the change of the patient's position. Compared with the above-mentioned prior art, the present invention can obtain the patient's respiratory state and the corresponding patient position information by setting a monitoring module for monitoring the patient's physiological parameters, and adjust the action parameters of the support module accordingly. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to adjust the specific parameters of the support scheme of the support module according to the patient's respiratory state and the patient's position change information at the same time, so as to achieve accurate lifting of the patient's mandibular angle and maintain stable opening of the airway. Specifically, the prior art only involves adjusting the patient's airway state by changing the respiratory state, thereby ignoring the impact of the patient's position change on the airway adjustment. For example, when the patient is lying down, the state of the airway can be adjusted through the mechanical motion pushing unit or the airbag inflation pushing unit in the above-mentioned prior art, and the lying position will not hinder the patient's airway adjustment process. However, when the patient is in a side-lying position, the relative position of the head and neck may be deflected, and the force parameters in a single direction cannot ensure that the patient's airway state can be adjusted to a preset state. Furthermore, the processing module of the present invention plans a support scheme that meets the patient's current state based on the acquired physiological parameters, which not only effectively ensures the patient's airway is unobstructed and eliminates the risk of suffocation during anesthesia surgery, but also can use the planning of the support scheme to ensure the patient's sleep quality and avoid frequent posture adjustments that affect the patient's normal rest.

[0014] According to a preferred embodiment, when the processing module is arranged in the main frame of the support module, the communication unit of the support module establishes a communication connection with the processing module in a wired manner. The processing module establishes a communication connection with the monitoring module integrated in the support module or the monitoring module located around the patient in a wired and / or wireless manner to obtain respiratory data, pressure data and image data in the physiological parameters. When the patient has abnormal breathing, since the medical staff does not monitor the patient all the time, the patient's abnormal condition can only be obtained through the patient's own interactive feedback with the call button or by the patient's bedside monitor. Therefore, when the patient's physiological parameters are determined by using the patient's bedside monitoring module (i.e., monitor), the patient's abnormal breathing can be determined by the processing module based on the physiological parameters provided by the monitoring module, and the processing module controls the support mode of the support module to open the patient's airway.

[0015] According to a preferred embodiment, the processing module analyzes the patient's respiratory state based on the respiratory data and determines whether the respiratory state is abnormal, so as to control the support module to adjust the patient's posture when the patient has abnormal breathing. The support module that the processing module plans out the corresponding support scheme can lift the patient's mandibular angle to move forward and upward, so that the patient's mandible protrudes to effectively open the airway. The processing module of the present invention can automatically detect the patient's respiratory state based on the respiratory data and make a judgment when an abnormality occurs, which greatly reduces the need for manual monitoring and improves work efficiency. Once abnormal breathing is detected, the processing module can quickly control the support module to adjust, which is particularly important for emergency situations that require rapid response (such as suffocation, airway obstruction, etc.). Through the planning of the processing module, the support module can accurately lift the patient's mandibular angle to move forward and upward, so that the patient's mandible protrudes, thereby effectively opening the airway. This precise adjustment can ensure the smooth flow of the patient's airway and prevent serious consequences caused by airway obstruction.

[0016] According to a preferred embodiment, the processing module determines the magnitude and direction of the force applied by the support module to the patient based on the pressure data, and then adjusts the angle and position of the support module to apply the support force to the patient to maintain the patient's airway open state. Compared with the above-mentioned prior art, the processing module of the present invention can obtain the magnitude and direction of the force applied by the support module to the patient according to the monitoring module, and adjust the angle and position of the support module to apply the support force to the patient according to the above data. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to timely adjust its actual force application parameters according to the change of the support state of the patient by the support module, so that the airway is continuously maintained in an open state. Specifically, the processing module of the present invention determines the magnitude and direction of the force applied by the support module to the patient based on the pressure data. This precise control can ensure that the support force is just right, which can effectively support the patient without causing unnecessary pressure or injury. When the magnitude and direction of the force applied by the support module change, the processing module can perceive in real time and make corresponding adjustments. This real-time adjustment capability can improve the patient's comfort while ensuring that the patient's airway is always in an open state. The processing module can automatically adjust the angle and position of the support module according to the pressure data. This automatic adaptation capability reduces the need for manual intervention and improves the automation of the inspection process.

[0017] According to a preferred embodiment, the processing module determines the current position of the patient based on the image data so that when the patient's position changes beyond the supportable range of the support module or when the distance between the patient and the support module exceeds the threshold, it is determined that the support module cannot continue to maintain the patient's airway open, and an alarm signal is sent to the prompt module. Compared with the above-mentioned prior art, the present invention can send an alarm signal when the support module exceeds its supportable range or when the distance between the patient and the support module exceeds the threshold in combination with the image data. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to prevent the adjustment function of the support module from failing and causing the patient's airway to be unable to open, thereby improving the reliability of the support module. Specifically, the processing module of the present invention can determine the current position of the patient based on the image data, which helps to monitor the patient's posture and position changes in real time, and ensure that the support module can adapt to the patient's dynamic changes. Since the processing module can monitor the patient's position and position changes in real time, once an abnormal situation occurs, an alarm signal can be quickly issued, and medical staff can respond quickly, thereby improving the response speed of the entire system. The present invention can reduce the need for manual monitoring and intervention, reduce the workload of medical staff, and improve work efficiency through an automatic monitoring and alarm system.

[0018] According to a preferred embodiment, when the processing module obtains the physiological parameters collected by the monitoring module, the processing module can determine the patient's breathing abnormality in combination with the changes in the patient's physiological parameters collected by the monitoring module at each time point, and plan the support scheme of the support module in combination with the patient's changes in body position and pressure when the patient has breathing abnormality. The processing module plans the precise lifting position required by the support module based on the physiological parameters, so that the support module can lift the patient's mandibular angle and forehead, and then make the patient's lower teeth exceed the upper teeth to effectively open the patient's airway. The processing module plans the support scheme of the support module in a target-related manner for opening the airway, such as time-related, efficiency-related, or accuracy-related.

[0019] According to a preferred embodiment, when the monitoring module detects that the patient's body position changes from supine to lateral position, the processing module calculates the support scheme of the support module and sends instructions to the support module to make corresponding posture adjustments to maintain the support of the patient's mandibular angle. During the adjustment stage, the processing module fine-tunes the position and force of the support module according to the physiological parameters monitored in real time to ensure that the patient's mandibular angle is accurately supported. For example, the processing module finely adjusts the force applied by the support module to achieve the best lifting effect.

[0020] According to a preferred embodiment, when the patient's breathing state returns to normal, the processing module changes the lifting state of the support module based on the patient's compression condition obtained by the monitoring module. If the pressure value of the patient's compression condition is not zero, the processing module controls the support module to maintain the current posture adjustment position to provide continuous breathing support for the patient. The processing module not only obtains the patient's breathing state in real time to determine the support scheme of the support module, but also realizes the lifting action of the patient's mandibular angle and forehead by the support module through precise posture adjustment. The present invention can effectively lift the patient's mandibular angle and ensure that the patient's airway is open through monitoring based on the monitoring module and posture adjustment of the support module.

[0021] Another aspect of the present invention also relates to an auxiliary airway opening method, the method comprising: judging the patient's respiratory state and the corresponding patient's body position based on the physiological parameters monitored by the monitoring module; adjusting the support scheme of the support module based on the patient's respiratory state, and adjusting the position, size and direction of the force point of the support module applying the support force according to the patient's body position change. The present invention combines real-time monitoring, judgment and posture adjustment to avoid airway obstruction caused by tongue posterior fall and oropharyngeal muscle collapse in painless digestive endoscopy or other environments, avoids complications such as hypoxemia in patients, and provides an effective protection measure for patients.

[0022] According to a preferred embodiment, the method also includes: when the processing module obtains the physiological parameters collected by the monitoring module, the processing module can determine the patient's breathing abnormality in combination with the changes in the patient's physiological parameters collected by the monitoring module at each time point, and plan the support scheme of the support module in combination with the patient's body position changes and pressure conditions when the patient has breathing abnormalities. The processing module of the present invention combines the changes in physiological parameters at multiple time points, which makes the judgment of the patient's breathing abnormality more accurate. By comprehensively analyzing multiple physiological parameters, the patient's condition can be more comprehensively understood and the reliability of diagnosis can be improved. In addition to the changes in physiological parameters, the processing module of the present invention also takes into account the patient's body position changes and pressure conditions, which makes the judgment of breathing abnormalities more comprehensive. This comprehensive assessment can better cope with different situations and improve the effectiveness of treatment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the protection scope of the present invention. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein.

[0034] First, the technical terms of the present invention are explained.

[0035] Mandibular angle: It is formed by the intersection of the posterior edge of the mandibular ramus and the lower edge of the mandibular body. The angle is related to age and chewing force. The bone surface of the inner and outer areas of the mandibular angle is rough, with the masseter muscle attached on the outside, the medial pterygoid muscle attached on the inside, and the stylomandibular ligament attached in the middle. The mandibular angle is one of the bony anatomical landmarks on the maxillofacial surface and is commonly used in craniofacial measurement.

[0036] Painless digestive endoscopy: It is a method that uses sedation and anesthetic drugs to eliminate or reduce the pain of patients during digestive endoscopy, thereby improving patients' acceptance of digestive endoscopy and enabling endoscopists to complete the diagnosis and treatment process more smoothly. Painless digestive endoscopy is applicable to multiple endoscopic diagnosis and treatment technologies such as gastroscopy, colonoscopy, enteroscopy, EUS, ERCP, EMR, ESD, and POEM.

[0037] Jaw support to open the airway is of great significance for painless digestive endoscopy. During painless digestive endoscopy, due to the use of anesthetic drugs, patients may experience respiratory depression, tongue drop, etc., leading to airway obstruction, and even suffocation and death in severe cases. Jaw support to open the airway can effectively solve this problem, keep the patient's airway open, and ensure that the patient safely goes through the examination process. In addition, jaw support to open the airway can also reduce the patient's pain and discomfort, improve the patient's tolerance and satisfaction, and enable endoscopists to complete the diagnosis and treatment process more smoothly. At the same time, for some patients who need emergency endoscopic examinations, jaw support to open the airway can quickly and effectively open the airway, buying precious treatment time for patients.

[0038] Example 1

[0039] In the prior art, there are simple support devices that can replace the manpower of medical staff to lift the patient's mandible, but the adjustment of the extension and contraction amount of this support device often relies on the experience of medical staff. If the pressure is adjusted too high, it will cause damage to the patient, and after this support device supports the patient's mandible, if the patient's body moves, it may cause the position of the support device and the patient's mandible to change, and the patient's mandible cannot be effectively and continuously lifted, resulting in the risk of suffocation. Patients with obstructive sleep apnea hypopnea syndrome may suffer from unconscious changes in body position during sleep, which may cause the patient's own respiratory arrest.

[0040] Moreover, in clinical practice, several diseases cause patients to have impaired consciousness, but clinicians fail to intubate the patients in time and / or the surgeons fail to manage the patients' airways after the patients are anesthetized in the surgical environment. In the above cases, clinicians or surgeons lack extra time to hold up the patient's mandible for a long time to ensure effective ventilation of the patient, which may cause the patient to have hypoxia due to tongue root falling back. For example, during painless digestive endoscopy, patients are prone to tongue falling back and oropharyngeal muscle collapse after anesthesia, which may cause airway obstruction and snoring in patients, and in severe cases, complete airway obstruction. Patients may experience hypoxemia in the above cases, which may be life-threatening. Currently, commonly used airway opening devices in clinical practice include oropharyngeal airways and nasopharyngeal airways. The oropharyngeal airway is highly irritating and has a lot of secretions, and is not suitable for gastroscopy of patients. The nasopharyngeal airway is highly irritating and the nasal mucosa is easily damaged and bleeding, which may easily cause the risk of aspiration in patients. It is known from evidence-based medicine that the mandibular support operation can improve the success rate of the first insertion, placement and positioning of the gastroscope and reduce the incidence of oropharyngeal soft tissue damage and postoperative pharyngeal pain for patients who need painless gastrointestinal endoscopy and undergo general anesthesia. Therefore, manual mandibular support is an effective and non-destructive method. However, it is difficult for clinicians, surgeons or other medical staff to maintain the mandibular support state for a long time. Therefore, the present invention aims to simulate the action of mandibular support by human hands, check the patient's abnormal breathing state to automatically support the patient's mandible, thereby opening the patient's airway and freeing the hands of medical staff.

[0041] In view of the deficiencies of the prior art, the present invention provides an auxiliary airway opening system and method. The present invention also provides an auxiliary airway opening system and method suitable for patients in the lateral position, which is used to open the airway of patients in the lateral position by simulating the action of supporting the mandible with a human hand, thereby freeing the hands of medical staff. The present invention can also provide a device for supporting the mandibular angle of a patient during painless digestive endoscopy, which is used to accurately adjust the direction, size and force application point of the device on the mandibular angle and forehead of the patient according to the patient's body position and abnormal breathing state. The present invention is mainly used in the process of painless digestive endoscopy of patients.

[0042] The present invention discloses an auxiliary airway opening system, such as Figure 6As shown, the system includes a support module 100 for lifting the mandibular angle and forehead of the patient, a processing module 200 located in the main frame of the support module 100 or in a remote computer room server, and a monitoring module 300 for monitoring the patient's physiological parameters. The processing module 200 located in the remote computer room server can execute the program of the method of the present invention based on the physiological parameters monitored by the monitoring module 300 to control the support module 100 to support. When the support module 100 is placed at the patient's bedside or other fixed position, the support module 100 uses its communication unit to establish a communication connection with the processing module 200. The processing module 200 can be integrated in the main frame of the support module 100, or it can be set in the server of the remote computer room. The processing module 200 of the system disclosed in the present invention is preferably integrated in the main frame of the support module 100 to adjust the support scheme of the support module 100 in a timely manner. When the processing module 200 is set in the main frame of the support module 100, the communication unit of the support module 100 establishes a communication connection with the processing module 200 in a wired manner. The processing module 200 disposed in the main frame of the support module 100 also establishes a communication connection with the monitoring module 300 integrated in the support module 100 or the monitoring module 300 located around the patient in an optical fiber Internet connection manner. The monitoring module 300 integrated in the support module 100 or located around the patient obtains the patient's respiratory data, pressure data, and image data and sends them to the processing module 200 located in the main frame of the support module 100 or in a remote computer room server. Figure 6As shown, the processing module 200 located in the main frame of the support module 100 or in the remote computer room server is connected to the hospital information system (Hospital Information System, HIS) in the medical institution through the Internet to store the respiratory parameter recording information and physiological parameter recording information generated by the patient during the breathing process. The processing module 200 located in the main frame of the support module 100 or in the remote computer room server can also be connected to the Internet with the image information system (Radiology Information System, RIS) to record, store and analyze the patient's body position changes during the breathing process. The processing module 200 located in the main frame of the support module 100 or in the remote computer room server analyzes the patient's respiratory state based on the respiratory data collected by the monitoring module 300 and determines whether the respiratory state belongs to abnormal breathing, thereby controlling the support module 100 placed at the patient's bedside to adjust the patient's posture when the patient has abnormal breathing. The processing module 200 that receives the pressure data fed back by the support module 100 determines the magnitude and direction of the force applied by the support module 100 to the patient based on the pressure data, and then adjusts the angle and position of the support force applied by the support module 100 to the patient, thereby maintaining the patient's airway patency. The processing module 200 that receives the patient image captured by the monitoring module 300 determines the patient's current body position based on the image data, and determines that the support module 100 cannot continue to maintain the patient's airway patency when the patient's body position changes beyond the supportable range of the support module 100 placed at the patient's bedside or when the distance between the patient and the support module 100 exceeds a threshold, and sends an alarm signal to the prompt module.

[0043] When the patient has abnormal breathing, since the medical staff does not monitor the patient all the time, the patient's abnormal condition can only be obtained through the patient's own interactive feedback with the call button or the patient's bedside monitor 301. Therefore, when the patient's physiological parameters are determined by the patient's bedside monitoring module (i.e., the monitor 301), the processing module 200 determines the patient's abnormal breathing according to the physiological parameters provided by the monitoring module, and the processing module 200 controls the support mode of the support module 100 to open the patient's airway. In particular, when the patient has abnormal breathing due to a change in body position, it is difficult for the support module 100 whose lifting mode has not been adjusted to effectively open the patient's airway. In this way, when the patient has abnormal breathing in the sleeping state of the bed or under surgical anesthesia, the processing module 200 in the main frame of the support module 100 or in the server in the remote computer room can adjust the support scheme of the support module 100 by combining "monitoring the changes in the patient's physiological parameters in a time-related manner and obtaining the patient's abnormal breathing" and "obtaining the patient's body position changes and pressure conditions when the patient has abnormal breathing". The support scheme is formulated in the initial use stage (i.e., the stage of installing the support module 100 beside the patient's bed) based on the position of the mandibular angle and forehead of the patient in the supine or lateral position. The processing module 200 identifies the mandibular angle and forehead of the patient based on the image data obtained by the monitoring module 300 to plan the support scheme of the support module 100. However, since the patient is not in a state of abnormal breathing for a long time and the body position may change accordingly, such as the patient may have intermittent abnormal breathing when sleeping, the physiological discomfort of the patient caused by abnormal breathing may change his body position. The support module 100 without adjusting the support scheme is difficult to accurately support the mandibular angle, and it cannot meet the accurate force point and force direction required for rescuing patients in abnormal breathing. In particular, the current jaw support devices are still limited to the method of lifting the patient's entire mandible by lifting the bracket, resulting in limited effect of opening the patient's airway, and the patient's abnormal breathing cannot be handled in time. If the patient's mandible is kept in a lifted state for a long time, it may also cause pressure sores or other complications in the patient. Therefore, how to determine whether the patient's abnormal breathing situation requires the intervention of the support module 100 and how to provide the correct support force application position, size and direction according to the patient's changed body position are technical problems to be solved by the present invention.

[0044] Specifically, when the patient is undergoing surgery and is located in the operating room, the processing module 200 built into the support module 100 determines the patient's current position based on the patient image data collected by the image acquisition sensor 303. The processing module 200 that determines the patient's corresponding position controls the support module 100 fixed to the operating bed to open the airway in response to the instructions of the medical staff or the patient's respiratory state. The processing module 200 controls the first arm 118 to approach the patient's mandibular angle based on the fixed position of the support module 100 located next to the bed and the patient's head bone points, and controls the second arm 116 to approach the patient's forehead. The processing module 200 uses an image processing algorithm to identify the collected image data based on the image processing algorithm to obtain the patient's head bone points. The head bone points can refer to the mandibular angle, forehead protrusion points, etc. The identification of these bone points can be achieved by comparing with a pre-set head anatomical model. When several bone points of the patient are identified, the processing module 200 calculates the position where the first arm 118 and the second arm 116 should approach to ensure that the robotic arm can accurately align with the patient's head. The processing module 200 sends instructions to the control structure in the support module 100 to adjust the position of the first arm 118 and the second arm 116. The first arm 118 will be positioned near the mandibular angle of the patient by the processing module 200, and the second arm 116 will be positioned near the forehead protrusion point, so that the end of the mechanical arm (i.e., the second gasket 113 and the third gasket 114) will be accurately placed on these bone points to provide stable support. The processing module 200 controls the first arm 118 and the second arm 116 to synchronously apply forces in opposite directions to the mandibular angle and forehead of the patient so that the mandible of the patient exceeds the upper jaw. The processing module 100 controls the control structure in the support module 100 to lift the mandibular angle of the patient by synchronously extending or rotating the second gasket 113 of the first arm 118 and the third gasket 114 of the second arm 116. After the processing module 200 positions the first arm 118 and the second arm 116, the processing module 200 also collects feedback data based on the pressure sensor 302, such as pressure distribution, head stability, etc. Thus, the processing module 200 adjusts the support force or force angle of the first arm 118 and the second arm 116 according to the feedback data to optimize the support effect and ensure the comfort and safety of the patient. The processing module 200 controls the first arm 118 and the second arm 116 of the support module 100 to at least continuously approach the mandibular angle and forehead of the patient to achieve a continuous airway opening state of the patient. Thus, the support module 100 can replace manual lifting of the mandibular angle of the patient.

[0045] When the patient is in a coma or sleeping state after general anesthesia and is located in a ward, the processing module 200 that receives the patient's physiological parameters collected by the monitoring module 300 determines the patient's respiratory state and the corresponding patient's body position based on the physiological parameters. When the processing module 200 determines that the patient is in an abnormal respiratory state, the processing module 200 controls the support module 100 fixed to the patient's bedside to open the airway. The processing module 200 controls the first arm 118 to approach the patient's mandibular angle based on the fixed position of the support module 100 located at the bedside and the patient's head bone point, and controls the second arm 116 to approach the patient's forehead. Preferably, when the patient enters a deep breathing or shortness of breath state, the processing module 200 detects a slight change in the patient's body position. In order to keep the patient's airway open and the body position stable, the processing module 200 immediately responds and adjusts the mechanical structure of the support module 100. The processing module 200 controls the ends of the first arm 118 and the second arm 116 (i.e., the first gasket 113 and the second gasket 114) to fine-tune the rotation angle so that they fit the mandibular angle and forehead of the patient more closely. In order to offset the changes in body position caused by breathing, the processing module 200 increases the supporting force of the first arm 118 and the second arm 116. This is achieved by increasing the contact pressure between the first gasket 113 and the second gasket 114 and the patient's skin. The processing module 200 adjusts the supporting angle of the first arm 118 and the second arm 116 according to the patient's breathing pattern and body position changes to ensure that the force is always perpendicular to the mandibular angle and forehead of the patient. In the case of apnea or dyspnea in the patient, the processing module 200 controls the control structure in the support module 100 so that the first arm 118 and the second arm 116 quickly and synchronously apply forces in opposite directions to the mandibular angle and forehead of the patient. In order to open the airway to the maximum extent, the processing module 200 controls the first gasket 113 and the second gasket 114 to cover the mandibular angle and forehead area of ​​the patient as much as possible, while increasing the force of the force application point.

[0046] like Figure 8 As shown, when the support module 100 and the monitoring module 300 are installed around the patient or beside the bed, the auxiliary airway opening method of the present invention further includes:

[0047] S1: The patient's physiological parameters are monitored by the monitoring module 300, and the processing module 200 determines the patient's respiratory state and the corresponding patient position based on the monitored physiological parameters.

[0048] In step S1, the processing module 200 in the main frame of the support module 100 or in the server in the remote machine room pre-plans a support scheme for controlling the support module 100 according to the patient's physiological parameters. Preferably, the processing module 200 pre-determines the required support force direction and force application point position of the patient in a certain body position according to the pre-planned support scheme. Due to the uncertainty of the patient's breathing state and body position changes in an unconscious state, it is necessary to obtain the patient's physiological parameters in real time through the monitoring module 300 to facilitate the subsequent operation of the support module 100. The primary goal of the support module 100 is to open the patient's airway to restore the patient's breathing state.

[0049] In the present invention, the above physiological parameters include the patient's height, weight, mandibular angle position, respiratory data, pressure data, and image data. The monitoring module 300 may include one or more sensors. Figure 6 As shown, the sensor can be a monitor 301 arranged beside the patient's bed, a pressure sensor 302 arranged at the contact point between the support module 100 and the patient's mandibular angle or forehead, and an image acquisition sensor 303 arranged in the patient's room. The monitor 301 can obtain the patient's vital signs, such as heart rate, blood pressure, blood oxygen saturation, etc. These data can be transmitted to the processing module 200 in real time to provide the processing module 200 with important respiratory data. The pressure sensor 302 is used to monitor the support force of the support module 100 on the patient, thereby reflecting the patient's pressure condition and ensuring that the pressure is not too large to cause pressure sores in the patient.

[0050] According to a preferred embodiment, the image acquisition sensor 303 of the monitoring module 300 sends the collected image data of the patient to the processing module 200. The image acquisition sensor 303 can be a camera in a ward or an operating room. The processing module 200 identifies and analyzes the image data to obtain the mandibular angle position and body position change of the patient. Preferably, the memory 201 of the processing module 200 contains a physiological structure database of patients of several body types, which has a variety of human physiological structures, including the mandibular angle position of patients of different body types. Preferably, the processing module 200 receives the image data and executes an image recognition algorithm on the image data to obtain the mandibular angle position and body position change of the patient. The above-mentioned image recognition algorithm can refer to that the processing module 200 obtains the mandibular angle position and body position change of the patient by comparing the image data obtained by the monitoring module 300 with the human physiological structure in the memory 201. Specifically, the step of the processing module 200 performing the comparison includes: comparing the image data collected by the monitoring module 300 with the human physiological structure in the memory 201 for bone points or other key points of the body according to the image recognition algorithm, and then outputting the comparison result. The comparison of the above-mentioned skeletal points or other body key points includes the comparison of at least two features. For example, the processing module 200 compares the patient's jaw position and facial features to match the patient's physiological structure. The processing module 200 determines the mandibular angle position of the patient in the body position based on the comparison results.

[0051] More preferably, the processing module 200 determines the stable state of the patient's body position according to the direction and size of the force applied to the patient's mandibular angle and / or forehead fed back by the pressure sensor 302 on the support module 100. The support module 100 can continuously monitor the position of the patient's mandibular angle by cooperating with the processing module 200. The change in the pressure state of the contact position between the support module 100 and the patient's mandibular angle can indirectly reflect whether the patient's body position is stable. This judgment is based on the assumption that the part where the support module 100 contacts the patient's mandibular angle in a stable state will not be significantly displaced. Preferably, the processing module 200 verifies the patient's body position change according to the physiological data provided by the monitoring module and the stable state fed back by the support module 100. If the body position change represented by the physiological data is consistent with the stable state fed back by the support module 100, it can be considered that the patient's body position has changed significantly. If the body position change represented by the physiological data is inconsistent with the stable state fed back by the support module 100, it may be necessary to further verify the accuracy of the relevant data and send an alarm signal to the medical staff's smart device. Through the information fed back by the support module 100, the processing module 200 can timely determine the unstable state of the patient's body position, so as to take corresponding mechanical structure adjustments to ensure the safety of the patient. For example, when the pressure sensor 302 of the support module 100 feedbacks that the force direction of the patient is shifted sideways, the processing module 200 determines that the patient may have a tendency to roll over. The processing module 200 adjusts the force direction of the support module 100 to intervene in the rollover trend. The force direction of the support module 100 can provide real-time feedback on the state of the contact part with the patient, which helps the processing module 200 to timely determine the patient's body position changes and take corresponding measures to adjust. If there is a large difference between the graphic data obtained by the monitoring module 300 and the patient's stable state feedback fed back by the pressure sensor 302 of the support module 100, the processing module 200 has an error correction function. This helps to improve the accuracy and reliability of monitoring and ensure accurate judgment of the patient's body position.

[0052] Preferably, when the patient's body position changes or the distance between the patient and the support module 100 changes beyond a set threshold, the processing module 200 determines that the support module 100 can no longer maintain the patient's airway open to send an alarm signal to the medical staff. The processing module 200 can send an alarm signal to the medical staff's smart device. The smart device is, for example, a smart phone, a smart watch, a walkie-talkie, etc. The alarm signal can be a text message reminder. For example, the alarm signal received by the medical staff's smart device is: Patient A in bed 37 of the respiratory department has apnea, and the position change exceeds the adjustable range. Please go to the ward in time to treat the patient. The alarm signal can also be a sound reminder or other way to alert medical staff through a smart device.

[0053] S2: The processing module 200 adjusts the support scheme of the support module 100 based on the patient's respiratory state, and adjusts the position, size and direction of the force application point of the support module 100 according to the patient's body position change.

[0054] Since the processing module 200 can plan a support scheme to be subsequently executed by the support module 100 based on the physiological parameters provided by the monitoring module 300, the support module 100 can lift the patient's mandibular angle at the corresponding angle and force point. In the case of abnormal breathing of the patient, the processing module 200 plans a support scheme that meets the patient's current state based on the acquired physiological parameters, which not only effectively ensures the patient's airway is unobstructed and eliminates the risk of suffocation during anesthesia surgery, but also can use the planning of the support scheme to ensure the patient's sleep quality and avoid frequent posture adjustments that affect the patient's normal rest.

[0055] Since the patient's breathing and body position can be reflected in real time by the physiological parameters obtained by the monitoring module 300, the processing module 200 can not only realize the automatic start and stop of the support module 100 by using the changes in the physiological parameters when the patient's abnormal breathing state occurs, but also plan the support scheme of the support module 100 for the patient. At this time, the support of the patient by the system of the present invention is not to lift the patient's entire mandible as in the prior art, but to lift the patient's mandibular angle to the front and top, that is, the support module 100 of the present invention lifts the patient's mandibular angle locally, and the local position of the mandibular angle can be the leftmost or rightmost end of the mandibular angle. The processing module 200 plans the precise lifting position required by the support module 100 based on the physiological parameters, so that the support module 100 can lift the patient's mandibular angle and forehead, and then make the patient's lower teeth exceed the upper teeth to effectively open the patient's airway. The processing module 200 plans the support scheme of the support module 100 in a target-related manner such as time-related, efficiency-related or accuracy-related to open the airway.

[0056] When the processing module 200 obtains the physiological parameters collected by the monitoring module 300, the processing module 200 can determine the patient's breathing abnormality in combination with the changes in the patient's physiological parameters collected by the monitoring module 300 at various time points, and plan the support scheme of the support module 100 in combination with the changes in the patient's body position and pressure conditions when the patient has breathing abnormalities. When the processing module 200 plans the support scheme of the support module 100, the processing module 200 at least uses "changes in the patient's physiological parameters" and "changes in body position and pressure conditions during breathing abnormalities" to plan the support scheme of the support module 100 with high precision. As a result, the support module 100 corresponding to the support scheme planned by the processing module 200 can lift the patient's mandibular angle to move forward and upward, thereby protruding the patient's mandible to effectively open the airway.

[0057] Preferably, the processing module 200 pre-plans the support scheme of the support module 100 in the initial use stage based on the patient's physical characteristics. For example, for a tall patient, the force application point of the support module 100 may need to be located near the neck to effectively open the airway. For a short patient, the force application point of the support module 100 may need to be adjusted downward to avoid excessive pressure on the patient's breathing.

[0058] Preferably, the processing module 200 determines the patient's respiratory state based on the physiological parameters obtained by the monitoring module 300, and then adjusts the support scheme of the support module 100. For example, if the monitoring module 300 finds that the patient's respiratory rate suddenly speeds up or slows down, the processing module 200 will immediately adjust the support scheme to adapt to the patient's current physiological needs. Specifically, the processing module 200 obtains the patient's apnea duration, the number of apneas, the blood oxygen saturation and / or the respiratory rate of the patient in the physiological parameters. When the patient's apnea duration exceeds the set threshold, or the number of apneas of the patient exceeds the threshold within a certain period of time, or the patient's blood oxygen saturation is lower than a certain threshold, or the patient's respiratory rate suddenly drops to a certain threshold, the processing module 200 determines that the patient has an abnormal respiratory state. The above thresholds can be set as: apnea duration exceeds thirty seconds; the number of apneas of the patient exceeds two times within one minute; the patient's blood oxygen saturation is lower than 90%; the respiratory rate drops to 8 times / minute or lower. Thus, the processing module 200 quickly determines the patient's respiratory state and then adjusts the support scheme of the support module 100.

[0059] S3: When the patient's breathing state returns to normal, the processing module 200 changes the lifting state of the supporting module 100 based on the patient's pressure condition obtained by the monitoring module 300.

[0060] When the patient's breathing state returns to normal, the processing module 200 monitors the patient's compression condition. If the pressure value of the patient's compression condition is monitored to be zero, it means that the patient's breathing state has returned to normal, and no further posture adjustment is required by the support module 100. If the patient's compression condition is monitored to be not zero, this may mean that the patient's breathing state has not returned to normal, or other abnormal conditions have occurred. In this case, the processing module 200 controls the support module 100 to maintain the current posture adjustment position and continue to provide respiratory support to the patient until his breathing state returns to normal.

[0061] In the above method, the processing module 200 not only obtains the patient's respiratory status in real time to determine the support scheme of the support module 100, but also realizes the lifting action of the support module 100 on the patient's mandibular angle and forehead through precise posture adjustment. The present invention can effectively lift the patient's mandibular angle and ensure that the patient's airway is open through the monitoring based on the monitoring module 300 and the posture adjustment of the support module 100. The present invention avoids the situation of airway obstruction caused by tongue posterior fall and oropharyngeal muscle collapse in painless digestive endoscopy or other environments, avoids complications such as hypoxemia in patients, and provides an effective protection measure for patients through the combination of real-time monitoring, judgment and posture adjustment.

[0062] Example 2

[0063] This embodiment is a further improvement on Embodiment 1, and the repeated contents will not be repeated here.

[0064] The present invention discloses an auxiliary airway opening system, such as Figures 1 to 5 As shown, the system includes a first arm 118 and a second arm 116. The first arm 118 is used to lift the patient's mandibular angle to open the patient's airway. The second arm 116 is used to press down the patient's forehead to tilt the patient's head back. The first arm 118 and the second arm 116 are connected to the fixed frame 101. The first arm 118 is rotatably connected to the fixed frame 101 through the second rotating shaft 106. The second arm 116 is rotatably connected to the fixed frame 101 through the fourth rotating shaft 117. The fixed frame 101 is detachably fixed to the rod body. The rod body can be an infusion stand beside the patient's bed. The fixed frame 101 is fixed to the rod body through a fixed clamping frame 103 and a clamping knob 105. A first rotating shaft 102 is provided at the connection between the fixed clamping frame 103 and the fixed frame 101, so that the fixed clamping frame 103 can rotate around the axis with the first rotating shaft 102 as the center of the circle. The contact positions of the fixed clamping frame 103 and the fixed frame 101 with the rod body are respectively provided with a first gasket 104. The first gasket 104 can increase the friction between the fixed clamping frame 103 and the fixed frame 101 and the rod body to prevent the fixed clamping frame 103 and the fixed frame 101 from slipping. A charging socket can be provided on the fixed frame 101. A power module for powering the movement of the first arm 118 and the second arm 116 is integrated in the fixed frame 101. The power supply mode of the power module is online charging or energy storage, so that the support module 100 of the present invention can continue to be used in the absence of a power socket or power outage. The auxiliary airway opening system of the present invention is fixed and stable, can be used at any time, and does not take up space. The fixed frame 101 can be adjusted up and down to achieve the movement of the mandibular support and thus change the position of the mandible.

[0065] Preferably, if Figure 2 , Figure 4As shown, the first arm 118 includes a first sub-arm 107 and a second sub-arm 111, which are connected by a third rotating shaft 110. The end of the first sub-arm 107 is fixed to the fixing frame 101 by the second rotating shaft 106. The end of the second sub-arm 111 is configured to fit the mandibular angle of the patient. The second sub-arm 111 is connected to the second gasket 113 that is in direct contact with the patient and is used to prevent the patient from being crushed by the first ball bracket 112. The first ball bracket 112 can be a universal joint. Preferably, one end of the second arm 116 is connected to the fixing frame 101, and the end of the other end is connected to the third gasket 114 that is in direct contact with the patient and is used to prevent the patient from being crushed by the second ball bracket 115. The end of the second arm 116 is configured to fit the forehead of the patient. The ends of the first arm 118 and the second arm 116 are configured to apply forces in opposite directions to the mandibular angle and forehead of the patient, respectively, so that the patient's mandible exceeds the upper jaw and maintains the patient's airway open. Preferably, a pressure sensor 302 for monitoring the magnitude and direction of the force applied to the patient is disposed in the second pad 113 and the third pad 114. The second pad 113 and the third pad 114 can be a slightly hard arc-shaped sheet or a soft pad.

[0066] Preferably, if Figure 3 and Figure 4 As shown, the first arm 118 and the second arm 116 are retractable mechanical arms. A positioning knob 108 is provided on the first sub-arm 107 of the first arm 118 to determine the retracted position of the first arm 118. Since the second arm 116 only fits the patient's forehead, there is no need to set an additional positioning knob 108. The first arm 118 is provided with a retractable portion 109 for retracting the first arm 118. The first arm 118 and the second arm 116 are provided with a control mechanism, such as a motor, for controlling a number of rotating shafts, a ball head bracket and the degree of retraction of the mechanical arm. The processing module 200 adjusts the support scheme of the support module 100 based on the physiological parameters obtained by the monitoring module 300, and adjusts the angle and position of the first arm 118 and the second arm 116 through the control mechanism according to the planned support scheme to maintain the patient's airway opening state.

[0067] Specifically, in the support scheme planned by the processing module 200, the processing module 200 determines the mandibular angle of the patient according to the patient's height and physiological structure to control the support module 100 to support it. Based on the planned support scheme, the processing module 200 drives the first arm 118 and the second arm 116 to perform corresponding actions through a control mechanism. These actions may include adjusting the angle, position and telescopic length of the mechanical arm. The positioning knob 108 on the first sub-arm 107 is used to determine the telescopic position of the first arm 118. The processing module 200 can set the length of the first sub-arm 107 by controlling the positioning knob 108. The telescopic portion 109 of the first arm 118 is used to realize the telescopic action of the mechanical arm. The processing module 200 controls the internal motor to drive the telescopic portion 109 to telescope, thereby realizing the length change of the first arm 118. The processing module 200 sets the force direction of the second gasket 113 and the third gasket 114. The processing module 200 controls the rotation angles of the first ball bracket 112 and the second ball bracket 115, thereby controlling the force directions of the second gasket 113 and the third gasket 114 on the patient's mandibular angle and forehead, respectively. The first ball bracket 112 and the second ball bracket 115 enable the first arm 118 and the second arm 116 to have a certain degree of rotational freedom to adapt to different patient positions.

[0068] In the present invention, the force direction of the support module 100 is set to an angle of 25° with the patient's mandibular angle to ensure effective lifting of the patient's mandibular angle to the front and upper displacement. The control mechanism of the present invention can be a device integrated inside the first arm 118 and the second arm 116, including a motor, a transmission device, a control circuit, etc., for driving the first arm 118 and the second arm 116 to perform precise movements. The control mechanism is connected to the mechanical arm through the transmission device. When the control mechanism receives the instruction of the processing module 200, the motor drives the mechanical arm to perform corresponding actions, such as telescoping, rotating, etc. The processing module 200 calculates the lifting distance of the patient's mandibular angle by the support module 100 based on the patient's physiological structure so that the patient's lower teeth exceed the upper teeth. Preferably, when the monitoring module 300 detects that the patient's body position changes from lying flat to lying on the side, the processing module 200 will quickly calculate a new support plan and send instructions to the support module 100 to make corresponding posture adjustments, such as rotating a certain angle to maintain stable lifting of the patient's mandibular angle. During the adjustment phase, the processing module 200 fine-tunes the position and force of the support module 100 according to the physiological parameters monitored in real time to ensure accurate support of the patient's mandibular angle. For example, the processing module 200 fine-tunes the force of the support module 100 to achieve the best support effect.

[0069] In the present invention, the first arm 118 and the second arm 116 have at least four degrees of freedom, corresponding adjustable angles and adjustable distance intervals. The processing module 200 determines whether the patient's position change exceeds the adjustable range of the support module 100 based on the determined degrees of freedom, adjustable angles and adjustable distance intervals, thereby issuing an alarm signal.

[0070] The auxiliary airway opening system of the present invention can be fixed on the infusion pole, and the pressure sensor 302 collects the pressure data of the support module 100 on the mandibular angle and forehead of the human body, so that the processing module 200 adjusts the angle and displacement of the first arm 118 and the second arm 116 to ensure that the first arm 118 and the second arm 116 of the auxiliary airway opening are stably connected and support the patient's mandible to prevent separation, and avoid excessive pressure on the patient's mandible to cause damage to the patient. In the case of movement of the patient's torso, the processing module 200 adjusts the position and angle of the first arm 118 and the second arm 116 to maintain the patient's airway opening.
