Description

Technical Field

[0001] The present invention belongs to the field of medical technology, and in particular relates to an intervention method and system for esophageal reflux in airway management. Background Art

[0002] Esophageal reflux, commonly known as gastroesophageal reflux disease (GERD), refers to the condition in which gastric contents flow backward into the esophagus, causing discomfort and complications. Its main causes include lower esophageal sphincter insufficiency, delayed gastric emptying, and esophageal clearance dysfunction. The symptoms of this disease are varied, including but not limited to heartburn, acid reflux, dysphagia, and throat discomfort. Its mechanism involves dysfunction of the lower esophageal sphincter, delayed gastric emptying, and disorders of the esophageal clearance mechanism. This disease not only affects the quality of life, but may also cause a series of complications, such as esophagitis, esophageal stenosis, and esophageal cancer.

[0003] It is worth noting that esophageal reflux is more common in certain populations, one of which is pregnant women. During pregnancy, increased gastroesophageal reflux may lead to accidental aspiration of gastric contents into the airway, which may cause suffocation or serious respiratory problems. Due to physiological changes in pregnant women, relaxation of the lower esophageal sphincter and increased abdominal pressure significantly increase the incidence of reflux. This aspiration not only causes coughing and suffocation, but may also lead to complications such as aspiration pneumonia, increasing the health risks of mother and baby.

[0004] Swelling of the soft tissue in the neck may have a significant impact on the patency of the airway. The swollen soft tissue may directly compress the airway, causing it to narrow, which in turn affects the flow of air, causing difficulty breathing or even suffocation. Even if the swelling does not completely block the airway, the narrowing of the airway will lead to reduced ventilation efficiency, causing the patient to experience symptoms such as shortness of breath and shortness of breath.

[0005] In clinical practice, doctors usually evaluate the swelling of the soft tissue in the neck and its effect on airway patency through visual inspection and palpation. This evaluation mainly relies on visual inspection and palpation, which is not only limited by the doctor's experience and skills, but also easily affected by subjective factors, resulting in inconsistent evaluation results.

[0006] Manual examinations are inefficient and cannot be timely. Low efficiency may result in patients not receiving timely intervention in a short period of time, increasing the risk of complications. In many cases, the manifestation of esophageal reflux-related symptoms may be intermittent, and doctors may not be able to capture the patient's true symptoms during examinations, resulting in missed or misdiagnosed diagnoses and delayed treatment.

[0007] When evaluating soft tissue swelling, doctors often rely on their personal palpation experience, which is easily affected by individual differences and may lead to misjudgment of the degree of swelling. At the same time, there is currently a lack of effective quantitative tools in clinical practice to evaluate the severity of soft tissue swelling in the neck and its specific impact on the airway, which makes doctors lack objective basis when formulating treatment plans. For these reasons, doctors may not be able to adjust the treatment plan in time when the condition changes, resulting in the patient's condition not being effectively controlled.

[0008] In summary, how to provide an intervention method and system for esophageal reflux in airway management is a technical problem that urgently needs to be solved. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an intervention method and system for esophageal reflux in airway management, which can generate a position adjustment plan based on the patient's current position and adjust the patient's current position, thereby reducing the risk of esophageal reflux aspiration caused by inappropriate position.

[0010] The present invention provides an intervention method for esophageal reflux in airway management, the method comprising the following steps: S1 collects risk assessment results to determine whether the patient has the risk of esophageal reflux aspiration; S2 identifies the patient's current body position when the patient is at risk of esophageal reflux aspiration; based on the current body position, determines the target body position and generates a body position adjustment plan; S3 adjusts the position of the patient's upper limbs and / or lower limbs through the position adjustment device, moves the patient's limbs from the first position to the second position, and makes the patient's limbs reach the characteristics of the target position in the position adjustment plan.

[0011] Further, identifying the patient's current body position in S2 includes identifying the position of the patient's upper limbs, the position of the upper limbs including at least the position of the patient's head; and identifying the position of the patient's lower limbs, the position of the lower limbs including at least the position of the patient's feet.

[0012] Furthermore, determining the target body position in S2 includes evaluating the relationship between the position information of each limb in the current body position and the risk of esophageal reflux aspiration, and extracting the limbs to be adjusted that are related to the risk of esophageal reflux aspiration; based on each limb to be adjusted, selecting a predetermined body position adjustment plan, or separately determining the adjustment method corresponding to each limb to be adjusted, and generating at least one body position adjustment plan based on the corresponding adjustment method.

[0013] Furthermore, after generating the posture adjustment plan, the method also includes screening the generated posture adjustment plan, including calculating the time and displacement distance taken for the patient to change from the current posture to the target posture; performing weighted operation on the time and displacement distance to obtain the operation result; comparing the operation results and selecting the posture adjustment plan with the minimum operation result.

[0014] Further, the calculation of the displacement distance of the patient from the current body position to the target body position includes selecting at least one of the patient's limbs to be adjusted as a reference point; obtaining the displacement distance between the reference point from a first position to a second position as the displacement distance of the patient from the current body position to the target body position.

[0015] Furthermore, it also includes classifying the patient's limbs into head limbs, trunk limbs and lower limbs according to their positions; selecting one limb to be adjusted from the head limbs, trunk limbs and lower limbs as a reference point in the corresponding category; calculating the displacement distance between each reference point from the first position to the second position, corresponding to the displacement distance of the head limbs, trunk limbs and lower limbs; taking the average value of the calculation results as the displacement distance of the patient from the current position to the target position.

[0016] Furthermore, the calculation of the time taken for the patient to change from the current position to the selected position includes collecting the patient's average movement speed data, or retrieving the patient's historical average movement speed data; and calculating the time taken based on the aforementioned displacement distance and average movement speed.

[0017] Furthermore, it also includes calibrating the historical average moving speed, including the following steps: collecting the patient's physical condition data, evaluating the impact of the disease on the patient's mobility, and generating a calibration coefficient.

[0018] Further, S3 includes sorting the limbs to be adjusted in the posture adjustment scheme according to different preset adjustment priorities; and performing operations on each limb to be adjusted in sequence based on the priority of each limb to be adjusted.

[0019] The present invention also provides a system using any one of the above-mentioned automatic intervention methods, including a body position adjustment device, which includes: Reflux aspiration risk management module, used to collect risk assessment results of whether the patient has the risk of esophageal reflux aspiration; A target body position acquisition module is used to identify the patient's current body position when the patient has a risk of esophageal reflux aspiration; based on the current body position, determine the patient's target body position and generate a body position adjustment plan; The body position adjustment module is used to adjust the patient's body position so that the patient's limbs reach the characteristics of the target body position in the body position adjustment plan.

[0020] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art, as an example: It can continuously monitor the patient's current position, develop an individual position adjustment plan, and adjust the patient's position to ensure that the patient is in a position that is conducive to reducing the risk of esophageal reflux aspiration.

[0021] For the generated posture adjustment plan, the time and displacement distance of the limbs when the posture is changed are calculated. The patient's limbs are classified to facilitate the selection of appropriate reference points when calculating the displacement distance, and the movement speed data is dynamically calibrated to improve the accuracy of the calculation.

[0022] By weighted calculation of the time and distance it takes for the patient to change from the current position to the target position, different position adjustment plans can be compared, the optimal plan can be screened out, the time and distance required for the patient's position adjustment can be reduced, and the timeliness of the patient's position adjustment can be ensured.

[0023] In addition, the limbs to be adjusted in the posture adjustment plan can be sorted according to the adjustment priority to ensure that the most critical limbs are adjusted first, thereby improving the targetedness and effectiveness of the intervention. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution disclosed in the present invention is described in detail below in conjunction with specific embodiments.

[0028] Techniques and methods known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques and methods should be considered part of the specification. In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0029] The present invention provides an intervention method for esophageal reflux, such as Figure 1 As shown, the method comprises the following steps: S1 collects risk assessment results to determine whether the patient has the risk of esophageal reflux aspiration.

[0030] The collection method is mainly through directly collecting relevant information of patients input by medical staff. The diagnosis of esophageal reflux disease usually depends on past medical history and clinical manifestations.

[0031] And; provide clinical information by collecting the patient's subjective feelings, such as whether there is a burning sensation in the stomach, nausea, vomiting, or acid reflux.

[0032] And / or, by collecting imaging and examination results, such as laryngoscopic images, gastroscopic images, 24-hour pH monitoring results, esophageal motility test results, and other objective data reflecting the functional and pathological changes of the esophagus and stomach.

[0033] Establish an identification checklist that identifies indicators associated with the risk of esophageal reflux aspiration based on literature and clinical practice, including but not limited to the following categories: Symptoms, such as burning sensation in the stomach, chest pain, nausea, or vomiting.

[0034] Medical history-related indicators, such as previous diagnosis of esophageal reflux disease, history of gastric ulcer or duodenal ulcer, bad living habits, whether pregnant, etc.

[0035] Imaging and examination results.

[0036] Biochemical indicators, such as Helicobacter pylori infection status and gastric acid secretion level.

[0037] The risk is determined and evaluated by comparing the collected results with the preset esophageal reflux aspiration risk-related contents on the list. The more items that meet the requirements, the higher the risk of esophageal reflux aspiration. When the number of items that meet the requirements exceeds the preset threshold, the patient is determined to have the risk of esophageal reflux aspiration and the subsequent steps are initiated.

[0038] S2 identifies the patient's current position.

[0039] Body position recognition can be achieved through a variety of technical means. As examples and not limitations, the following are some of the implementation methods: The patient's movement and position are monitored through sensors, for example, small wearable sensors are set on the patient, including but not limited to accelerometers, gyroscopes, etc. Among them, accelerometers can detect changes in acceleration, and gyroscopes are used to measure angular velocity. The combination of the two can provide movement information in three-dimensional space.

[0040] The sensor may also include a pressure sensor, which may be arranged on the contact surface of the seat or mattress contacting the patient, or may be arranged as a patch on different parts of the patient's body. When the patient changes posture or moves, the contact pressure of different parts will change, and the data of pressure distribution, size, and change trend are collected and analyzed to judge the patient's posture and posture change.

[0041] In addition, image acquisition equipment, such as cameras and / or infrared sensors, can be installed in the space where the patient is located to shoot the patient from different angles, capture the patient's real-time image, and analyze these images to select some preset limb parts as key limb parts for identification, such as the patient's head, arms, ankles, chest, etc.; track the positions of these key limb parts, and obtain the patient's body position information by analyzing the positions and relative relationships of the key points. By analyzing the movement trajectory of the key limb parts, the patient's motion information can be obtained.

[0042] S2 identifies the patient's current body position, including identifying the position of the patient's upper limbs, the position of the upper limbs including at least the position of the patient's head; and identifying the position of the patient's lower limbs, the position of the lower limbs including at least the position of the patient's feet.

[0043] Through the body position recognition method described above, the head and foot positions are given priority over other limb parts during data collection and processing.

[0044] Choose a plane as a height reference and compare the position information of the head and feet to compare the heights of the two.

[0045] Take a patient lying on the bed as an example, with the ground or wound surface as the reference plane, assuming the coordinate value in three-dimensional space, the coordinate of the head position is (x h , y h , z h ), the coordinates of the foot position are (x f , y f , z f ).

[0046] By comparing z h and z f The size of the head and feet can be used to determine the height difference between the head and feet relative to the reference plane.

[0047] S2 determines the patient's target body position based on the current body position.

[0048] The target position has a lower risk of esophageal reflux aspiration than the current position.

[0049] Determining the patient's target position in S2 includes evaluating the relationship between the position information of each limb in the current position and the risk of esophageal reflux aspiration, and extracting the limbs to be adjusted that are related to the risk of esophageal reflux aspiration.

[0050] Specifically, the position information of the patient's head is evaluated to see whether it is at an appropriate height by comparing it with the positions of other limbs. For example, by comparing the head position with the abdominal position, it is found that the patient's head position is too low, and the head is lower than the stomach, which will lead to increased abdominal pressure and thus an increased risk of esophageal reflux aspiration. Based on the above analysis, the head is determined to be a limb to be adjusted that is related to the risk of esophageal reflux aspiration and is extracted.

[0051] For another example, after comparing the position information of the patient's torso and legs, if the patient's torso and legs are at the same height, or even lower than the legs, the current position of the torso is judged to have a risk of esophageal reflux aspiration and is extracted as the limb to be adjusted.

[0052] After extracting all the limbs to be adjusted that are related to the risk of esophageal reflux aspiration, determine the corresponding adjustment methods based on each limb to be adjusted. The adjustment method includes adjusting the limb to be adjusted from the first position where the risk of esophageal reflux aspiration is higher to the second position where the risk of esophageal reflux aspiration is lower, so that the patient changes from the current position to the target position. The change of the second position relative to the first position includes at least one of the following three types: change in height, change in relative position, and change in angle. The target position of the patient is formed by the convergence of the position features of the limb to be adjusted in the second position.

[0053] Specifically, for the head of the limb to be adjusted that is lower than the abdomen, the corresponding adjustment method is to lift the head from the first position to a second position with a higher height.

[0054] If it is detected that the torso is lower than the legs, the torso support needs to be strengthened, and the corresponding adjustment method is to raise the torso from the first position to the second position with a higher height.

[0055] A predetermined posture adjustment plan is subsequently selected, or a posture adjustment plan is generated based on the judgment results.

[0056] Furthermore, considering that the adjustment of each limb takes time, in order to save time as much as possible, the current body position is adjusted to the target body position with a lower risk of reflux and aspiration as soon as possible, and it is not necessary to adjust each limb to be adjusted. At least one limb to be adjusted and its corresponding adjustment method are selected as a separate body position adjustment plan, and a plurality of body position adjustment plans are generated according to the types and differences of the selected limb to be adjusted.

[0057] The generated posture adjustment plans are screened, including calculating the time and displacement distance required for the patient to change from the current posture to the target posture.

[0058] The method for calculating the displacement distance of the patient from the current body position to the target body position includes selecting at least one of the patient's limbs to be adjusted as a reference point; taking the first position of the reference point as the starting point and the second position as the end point, and obtaining the displacement distance of the reference point from the first position to the second position.

[0059] For example, the initial position of the patient's nose is selected as the reference point, the patient's nose is identified, its current first position is recorded, and the displacement distance of the patient's other limbs including the head is extracted in the position adjustment plan. The initial position of each limb of the patient is recorded, and the target position (X 当前 , Y 当前 , Z 当前 ), based on the initial position coordinates, and the target position coordinates (X 目标 , Y 目标 , Z 目标 ), for example, by the following formula: Displacement distance

[0060] That is, the patient's nose is used to represent the patient's entire body, and the displacement distance D is regarded as the displacement distance of the patient from the current body position to the target body position.

[0061] Or, further, when calculating the displacement distance, the various limb parts of the patient are classified according to their positions, preferably, divided into head limbs, trunk limbs and lower limbs from top to bottom; in each category, one limb to be adjusted is selected as a reference point for all limb parts to be adjusted in that category.

[0062] Specifically, the head and limbs refer to the limbs on the head, including eyes, nose, ears, etc. As an example, the head and limbs select the eyes, such as the left eye, as the reference point. That is, the calculated displacement distance of the left eye from the first position to the second position represents the displacement distance of all the limbs to be adjusted in the body position adjustment that are classified under the head and limbs category.

[0063] The trunk and limbs refer to the limbs below the head and above the legs, including the chest, abdomen, back, etc. As an example and not a limitation, the trunk and limbs use the navel as a reference point. Similarly, the displacement distance of the trunk and limbs from the current position to the target position is regarded as the calculation result of the displacement distance of the navel from the first position to the second position.

[0064] The lower limbs refer to the legs and the parts of the body below the legs, including the thighs, calves, feet, etc. As an example, the foot is selected as the reference point.

[0065]

[0066] The patient's displacement distance D from the current position to the target position is classified into three categories, namely, the average value of the calculated displacement distances of the head and limbs, the trunk and limbs, and the lower limbs.

[0067] The time spent includes estimating the average moving speed of the patient; the average moving speed of the patient can be obtained by the various relevant functional components for monitoring the position and movement of the patient described in the previous embodiments.

[0068] Taking the accelerometer and gyroscope as an example, the three-dimensional motion data provided by the accelerometer can reflect the patient's movement direction and speed changes, and then the average movement speed can be obtained through time integration. The combination of gyroscope and accelerometer can more accurately identify the patient's movement state and direction.

[0069] The pressure sensor can estimate the movement rate of the limbs by detecting the changes in pressure at different time points.

[0070] The image acquisition device tracks the patient's movement trajectory by analyzing the real-time images. By analyzing the time series of these positions, the patient's movement speed can be calculated.

[0071] The above average moving speed may be for the patient as a whole, and all limbs of the patient may be considered to move at this speed, or it may be further refined to obtain the moving speeds of different limbs separately.

[0072] Alternatively, for patients with a medical record, the patient's historical average moving speed data can be directly retrieved, and further, calibration can be performed in combination with the patient's physical condition data.

[0073] The patient's physical condition data includes the hospital's diagnostic data on the patient and / or the patient's real-time physiological data. The hospital's diagnostic data on the patient can be obtained by reading the data from the hospital's electronic medical record system; the patient's real-time physiological data can be obtained by setting relevant functional components for collecting physiological data on the patient, including but not limited to heart rate monitors, blood pressure detectors, body temperature detectors, etc.

[0074] Based on the patient's physical condition data, determine whether his or her condition will affect his or her mobility, and evaluate the degree of impact of the condition on his or her mobility. For example, the condition is scored from 1 to 5, where 1 indicates no impact and 5 indicates severe impact.

[0075] According to different scoring results, corresponding calibration parameters are generated to adjust the historical average moving speed.

[0076] The specific implementation steps are as follows: .

[0077] If the disease score is 3, the adjustment factor is 0.4, which means that the historical average movement speed will be reduced by 40%.

[0078] The calibrated average moving speed = historical average moving speed * (1 + adjustment factor).

[0079] The time taken is calculated based on the above displacement distance and average moving speed.

[0080] Furthermore, the method further includes calibrating the calculation result of the time spent, including the following steps: collecting the patient's physical condition data and / or the patient's time spent; generating a calibration coefficient based on the collected result; The time spent and the displacement distance are weighted to obtain the calculation result.

[0081] The weighted calculation method is taken as an example but not limited to multiplying the time spent and the displacement distance. Alternatively, the time spent and the displacement distance are added.

[0082] Sort the calculation results from large to small, and select the posture adjustment plan with the minimum calculation result.

[0083] S3 adjusts the position of the patient's upper limbs and / or lower limbs through the position adjustment device to move the patient's limbs from the first position to the second position.

[0084] The body position adjustment device here can be selected from at least one of a robotic arm, a bed capable of adjusting height and angle, an intelligent robot-assisted device, and other devices capable of adjusting the position of the patient's limbs from the head to the feet.

[0085] like Figure 2 As shown, the body position adjustment device 100 includes a plurality of mechanical arms 110 and an adjustable bed 120 .

[0086] The principle and structure of the above device can refer to the structure and principle of the existing device, and will not be elaborated in detail here.

[0087] The body position adjustment device moves the limb part to be adjusted from the current first position to the second position in the body position adjustment scheme.

[0088] Optionally, the limbs to be adjusted in the posture adjustment scheme are sorted according to different preset adjustment priorities. The adjustment priority and the influence of the limbs on the risk of reflux aspiration form a positive relationship.

[0089] Optionally, the patient's head and the patient's body are set to have a higher adjustment priority. In the case where the limbs to be adjusted include the patient's head and / or the patient's body, the adjustment operations for these two limbs to be adjusted are performed preferentially.

[0090] Other limbs to be adjusted with higher adjustment priorities will have their related adjustment operations performed first compared to limbs to be adjusted with lower adjustment priorities.

[0091] After the adjustment is completed through the above steps, the patient's limbs reach the characteristics of the target position in the position adjustment plan, which at least includes that the patient's head position is lower than the foot position, and / or that the patient's body is in a right-side lying position.

[0092] The present invention provides a system using any one of the intervention methods described above, comprising a body position adjustment device, including: Reflux aspiration risk management module, used to collect risk assessment results of whether the patient has the risk of esophageal reflux aspiration; A target body position acquisition module is used to identify the patient's current body position when the patient has a risk of esophageal reflux aspiration; based on the current body position, determine the patient's target body position and generate a body position adjustment plan; The body position adjustment module is used to adjust the patient's body position so that the patient's limbs reach the characteristics of the target body position in the body position adjustment plan.
