Description

Technical Field

[0001] The present invention relates to the technical field of stomach-stomach-destroying capsule management systems, and in particular to a stomach-stomach-destroying capsule intelligent satiety management system and a method thereof. Background Art

[0002] With the improvement of living standards and changes in eating habits, obesity and its related chronic diseases (such as diabetes, hypertension, etc.) have become important health issues of global concern. Scientific, safe and effective weight management has become a hot topic in today's medicine and health management field. As a non-invasive satiety management tool, Zhanwei Capsule occupies stomach capacity through physical means, thereby reducing food intake. It is an innovative product that has attracted much attention in recent years.

[0003] The prior art has the following deficiencies:

[0004] After the traditional stomach-occupying capsule expands to a preset volume in the stomach, it cannot be dynamically adjusted according to the actual capacity or state of the user's stomach. If the capsule volume is too large in actual application, it may cause a heavy burden on the stomach, causing stomach discomfort or even damage.

[0005] Based on this, the present invention proposes an intelligent satiety management system for stomach-stomach capsules and a method thereof. Through the initial expansion volume and subsequent primary and secondary expansion adjustment mechanisms, the volume is adjusted according to the user's stomach capacity and real-time gastric status data to avoid damage caused by excessive expansion and achieve a safe and comfortable user experience. Summary of the invention

[0006] The purpose of the present invention is to provide a stomach-sucking capsule intelligent satiety management system and method thereof to overcome the deficiencies in the background technology.

[0007] In order to achieve the above object, the present invention provides the following technical solution: a method for intelligent satiety management of stomach-stomach capsule, the management method comprising the following steps:

[0008] The management system obtains the stomach-sucking capsule information through the stomach-sucking capsule control platform, and the stomach-sucking capsule information includes the initial expansion volume of the stomach-sucking capsule and the model of the stomach-sucking capsule;

[0009] After the stomach-sucking capsule has been in the user's stomach for a period of time, the stomach status data is collected through the built-in sensor of the stomach-sucking capsule, the stomach status data is substituted into the intelligent adjustment rule for analysis, and the expansion volume of the stomach-sucking capsule is adjusted once;

[0010] After obtaining the intragastric state data and intragastric pressure at regular intervals, it is determined whether the expansion volume of the stomach-occupying capsule needs to be adjusted for a second time, and a corresponding control strategy is generated according to the determination result.

[0011] In a preferred embodiment, the stomach status data is collected by a sensor built into the stomach capsule, and the stomach status data includes a temperature index, a gastric motility index, and a pH index.

[0012] In a preferred embodiment, substituting the intragastric state data into the intelligent regulation rule analysis includes the following steps:

[0013] The processing logic of the intelligent adjustment rule is: normalize the temperature index, gastric motility index and pH index, map the value range of the temperature index, gastric motility index and pH index to [0,1], obtain the normalized value of the temperature index, the normalized value of the gastric motility index and the normalized value of the pH index, and sum the normalized value of the temperature index, the normalized value of the gastric motility index and the normalized value of the pH index to obtain the intragastric influencing factor.

[0014] In a preferred embodiment, adjusting the expansion volume of the stomach capsule once comprises the following steps:

[0015] After obtaining the intragastric influence factor, the initial expansion volume of the gastric capsule is adjusted once according to the intragastric influence factor. The adjustment algorithm expression is: Where volume one To adjust the expansion volume once, volume old is the initial expansion volume, effect is the influencing factor in the stomach, and the management system remotely controls the stomach capsule through wireless technology to adjust the expansion volume once.

[0016] In a preferred embodiment, after regularly acquiring the intragastric state data and intragastric pressure, determining whether it is necessary to adjust the expansion volume of the stomach-occupying capsule for a second time comprises the following steps:

[0017] Obtain the intragastric influencing factor and intragastric pressure regularly, first calculate and obtain the intragastric pressure fluctuation amplitude, and then comprehensively calculate the intragastric influencing factor and the intragastric pressure fluctuation amplitude to obtain the adjustment coefficient, the expression is: adjust = ω1 × effect + ω2 × pressure, where adjust is the adjustment coefficient, effect is the intragastric influencing factor, pressure is the intragastric pressure fluctuation amplitude, ω1 and ω2 are the weights of the intragastric influencing factor and the intragastric pressure fluctuation amplitude respectively, and 0<ω1<ω2<1;

[0018] The obtained adjustment coefficient is compared with the preset adjustment threshold. The adjustment threshold is used to determine whether it is necessary to adjust the expansion volume of the stomach-stomach capsule for the second time. If the adjustment coefficient is less than the adjustment threshold, it is determined that it is not necessary to adjust the expansion volume of the stomach-stomach capsule for the second time. If the adjustment coefficient is greater than or equal to the adjustment threshold, it is determined that it is necessary to adjust the expansion volume of the stomach-stomach capsule for the second time.

[0019] In a preferred embodiment, generating a corresponding control strategy according to the judgment result includes the following steps:

[0020] When it is determined that the expansion volume of the Zhanwei capsule does not need to be adjusted twice, the management system controls the Zhanwei capsule to adjust the expansion volume once. When it is determined that the expansion volume of the Zhanwei capsule needs to be adjusted twice, the management system adjusts the expansion volume of the Zhanwei capsule twice through the adjustment coefficient. The expression is:

[0021] volume two =volume one / ln(adjust+1), in the formula, volume one To adjust the expansion volume once, volume two is the secondary adjustment of expansion volume, and adjust is the adjustment coefficient.

[0022] In a preferred embodiment, the calculation logic of the temperature index is as follows: obtaining the current temperature and the previous temperature in the stomach within the monitoring period, subtracting the previous temperature from the current temperature to obtain the temperature difference, obtaining the temperatures at multiple time points within the monitoring period, calculating the average temperature, dividing the temperature difference by the monitoring period to obtain the temperature rise rate, and multiplying the temperature rise rate by the average temperature to obtain the temperature index;

[0023] The calculation logic of the gastric motility index is as follows: obtaining the gastric motility speed at the current moment and the gastric motility speed at the previous moment in the stomach within the monitoring time period, subtracting the gastric motility speed at the current moment from the gastric motility speed at the previous moment to obtain the gastric motility speed difference, obtaining the gastric motility speed at multiple time points within the monitoring time period, calculating the average gastric motility speed, dividing the gastric motility speed difference by the monitoring time to obtain the gastric motility speed decrease rate, and multiplying the gastric motility speed decrease rate by the average gastric motility speed to obtain the gastric motility index;

[0024] The calculation logic of the pH index is as follows: obtain the current pH value and the previous pH value in the stomach within the monitoring time period, subtract the current pH value from the previous pH value to obtain the pH value difference, obtain the pH values ​​at multiple time points within the monitoring time period, calculate the average pH value, divide the pH value difference by the previous monitoring value to obtain the pH decrease rate, and multiply the pH decrease rate by the average pH value to obtain the pH index.

[0026] Information acquisition module: obtains the Zhanwei capsule information through the Zhanwei capsule control platform, and the Zhanwei capsule information includes the initial expansion volume of the Zhanwei capsule and the Zhanwei capsule model;

[0027] Adjustment module: After the stomach-sucking capsule has been in the user's stomach for a period of time, the stomach status data is collected through the built-in sensor of the stomach-sucking capsule, the stomach status data is substituted into the intelligent adjustment rule analysis, and the expansion volume of the stomach-sucking capsule is adjusted once;

[0028] Strategy generation module: after regularly acquiring the intragastric status data and intragastric pressure, it determines whether it is necessary to adjust the expansion volume of the stomach-occupying capsule for the second time, and generates a corresponding control strategy based on the judgment result.

Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0032] Figure 1 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 As shown, the present embodiment provides a method for intelligent satiety management of stomach-satisfying capsules, and the method comprises the following steps:

[0035] The management system obtains the stomach-sucking capsule information through the stomach-sucking capsule control platform. The stomach-sucking capsule information includes the initial expansion volume of the stomach-sucking capsule and the model of the stomach-sucking capsule (usually a doctor or professional will recommend a suitable capsule model and initial expansion volume based on the user's stomach capacity, health status and eating habits). After the stomach-sucking capsule has been in the user's stomach for a period of time, the stomach status data is collected through the built-in sensor of the stomach-sucking capsule, and the stomach status data is substituted into the intelligent adjustment rule for analysis. The expansion volume of the stomach-sucking capsule is adjusted once. After obtaining the stomach status data and stomach pressure at regular intervals, it is determined whether the expansion volume of the stomach-sucking capsule needs to be adjusted for a second time, and a corresponding control strategy is generated based on the judgment result.

[0036] This application obtains the information of the stomach capsule through the stomach capsule control platform. The information of the stomach capsule includes the initial expansion volume of the stomach capsule and the model of the stomach capsule. After the stomach capsule enters the user's stomach for a period of time, the stomach state data is collected through the built-in sensor of the stomach capsule, and the stomach state data is substituted into the intelligent adjustment rule analysis, and the expansion volume of the stomach capsule is adjusted once. After obtaining the stomach state data and stomach pressure at regular intervals, it is determined whether the stomach capsule needs to be adjusted for the expansion volume twice, and a corresponding control strategy is generated according to the judgment result. The management system adjusts the volume according to the user's stomach capacity and real-time stomach state data through the initial expansion volume and subsequent one-time and two-time expansion adjustment mechanism, to avoid the damage caused by excessive expansion and achieve a safe and comfortable user experience.

[0037] Examples of application scenarios for this application:

[0038] User background: Ms. Zhang is a middle-aged woman who is trying to lose weight. She is overweight and has a habit of overeating. She has tried various weight loss methods, but has not achieved the desired results due to difficulty in controlling her diet.

[0039] Solution application: Ms. Zhang chose Zhanwei Capsule as an auxiliary weight loss tool under the guidance of her doctor. The doctor recommended a suitable capsule model for her based on her stomach capacity, health status and eating habits, and set the initial expansion volume.

[0040] After the capsule enters the stomach, the built-in sensor begins to monitor Ms. Zhang's gastric status data in real time, including gastric pressure, temperature, pH value, etc. As the capsule gradually expands, the management system analyzes the gastric environment based on the sensor data, and makes the first expansion adjustment to the capsule volume according to the intelligent adjustment rules. If the gastric pressure is too high or the temperature rises too quickly over a period of time, the system will automatically reduce the expansion volume of the capsule to avoid causing stomach discomfort or injury. If Ms. Zhang's gastric environment continues to be unstable, the system will make a secondary adjustment to ensure that the capsule volume remains within a safe and comfortable range to avoid excessive expansion. Throughout the process, the management system always makes dynamic adjustments based on Ms. Zhang's stomach capacity and real-time data to help her maintain a long-term sense of fullness and reduce unnecessary eating, thereby achieving her weight loss goals.

[0041] User background: Mr. Li has just undergone stomach surgery (such as gastric bypass surgery) and needs to adopt a gentler diet control method to help his stomach recover and avoid discomfort caused by overeating.

[0042] Solution application: The doctor recommended that Mr. Li use the Zhanwei Capsule to control his food intake and ensure that he would not experience excessive stomach pressure or discomfort due to excessive food intake during the recovery period. Mr. Li's initial expansion volume was set by the doctor based on the stomach capacity after surgery, and the expansion volume was ensured not to be too large to avoid unnecessary pressure on the stomach wall. The management system monitors Mr. Li's stomach status through built-in sensors and adjusts the expansion volume of the capsule in real time. If the system detects that the pressure in the stomach is too high, it may be because the stomach capacity is too small or it is over-expanded. The system will automatically reduce the volume of the capsule to ensure the comfort and safety of the stomach. Through this dynamic adjustment, Mr. Li can feel a longer-lasting sense of fullness and avoid overeating, while also preventing stomach discomfort or other health risks due to excessive expansion.

[0043] User background: Mr. Wang has been suffering from gastroesophageal reflux disease (GERD) for a long time. Excessive stomach acid and bloating often make him feel uncomfortable. The doctor recommended that he use Zhanwei Capsules to help reduce food intake and reduce the burden on the stomach.

[0044] Solution application: Mr. Wang uses the stomach-sucking capsule to regulate his food intake according to the doctor's advice. The initial expansion volume of the capsule is set in a range suitable for Mr. Wang's stomach health to ensure that the stomach pressure is not too high due to excessive expansion. During use, the management system monitors the status data in the stomach in real time through built-in sensors, such as stomach temperature, gastric acid concentration and pressure. If the gastric acid concentration is too high or the gastric pressure is increased, the system will immediately adjust the expansion volume of the capsule, reducing its volume to relieve the burden on the stomach and prevent stomach discomfort. During Mr. Wang's use, the system always adjusts the expansion volume of the capsule according to real-time data to avoid excessive expansion in the stomach, ensure stomach health, reduce symptoms of chronic gastric disease, and improve comfort.

[0045] User background: Mr. Liu is an office worker who sits for a long time and has little activity. He is prone to overeating, which causes stomach bloating and discomfort. Mr. Liu hopes to use Zhanwei Capsules to help control his food intake and avoid overeating.

[0046] Solution application: Mr. Liu started using the Zhanwei Capsule on the advice of his doctor. The initial expansion volume is set according to Mr. Liu's weight and stomach capacity to ensure that he will not feel uncomfortable due to excessive expansion. The management system determines the state of the stomach by monitoring the intragastric state data (such as pressure, temperature, and pH value). If Mr. Liu's intragastric pressure rises due to prolonged sitting for a period of time, the system will automatically adjust the expansion volume of the capsule to reduce the pressure and ensure that the stomach is not overly compressed. Throughout the process, the capsule will dynamically adjust the expansion volume based on real-time data to help Mr. Liu effectively control his food intake, reduce stomach discomfort, improve eating habits, and lose weight.

[0047] The above solution is suitable for users in different scenarios. By real-time monitoring of the state of the stomach and adjusting the expansion volume of the stomach capsule according to the individual situation of the user, it can help users achieve safer and more comfortable satiety management, avoid discomfort or health risks caused by excessive expansion, and help maintain long-term diet control. It is suitable for weight loss, postoperative recovery, chronic gastric disease management and other scenarios. .

[0048] Embodiment 2: The management system obtains stomach capsule information through the stomach capsule control platform, and the stomach capsule information includes the stomach capsule initial expansion volume and stomach capsule model (usually doctors or professionals will recommend a suitable capsule model and initial expansion volume based on the user's stomach capacity, health status and eating habits), including the following steps:

[0049] The management system obtains the information of the stomach capsule, including the initial expansion volume and capsule model, through the stomach capsule control platform. This information is usually recommended by doctors or professionals based on the user's stomach capacity, health status and eating habits to ensure the selection of the appropriate capsule model and initial expansion volume in order to effectively control satiety and ensure safety.

[0050] Suppose there is a user A who has a small stomach capacity and is in the stage of losing weight. The doctor recommends the use of a capsule suitable for a small stomach capacity and recommends a suitable initial expansion volume based on his health condition. The management system generates corresponding capsule configuration information based on this information, and the management system obtains relevant information about the stomach capsule through the stomach capsule control platform. Including: the initial expansion volume of the stomach capsule. The model of the stomach capsule (based on the needs of different users, doctors or professionals will recommend a suitable model to ensure the expansion effect and safety). The user's stomach capacity, health condition and eating habits, this information helps determine the appropriate initial expansion volume;

[0051] Provide customized capsule model and expansion volume based on the user's stomach capacity, health status and other information to ensure that each user's needs are met.

[0052] The information of the stomach capsule is shown in Table 1:

[0053]

[0054] Table 1

[0055] As shown in Table 1, the system obtains the user's stomach capacity, health status, eating habits and other data through the user's health record or the information provided by the doctor. Based on the above information, the doctor or professional selects the appropriate capsule model and initial expansion volume and records it on the control platform. The stomach capsule control platform receives the capsule model and initial expansion volume provided by the user and the doctor and saves them. This data can be used for subsequent adjustment operations and monitoring.

[0056] After the stomach-sucking capsule enters the user's stomach for a period of time, the stomach status data is collected by the built-in sensor of the stomach-sucking capsule, including the following steps:

[0057] The built-in sensor of the stomach capsule is used to collect the gastric status data, including temperature index, gastric motility index and pH index;

[0058] The calculation logic of the temperature index is as follows: obtain the current temperature and the previous temperature in the stomach during the monitoring period, subtract the current temperature from the previous temperature to obtain the temperature difference, obtain the temperatures at multiple time points during the monitoring period, calculate the average temperature, divide the temperature difference by the monitoring time to obtain the temperature rise rate, and multiply the temperature rise rate by the average temperature to obtain the temperature index.

[0059] The calculation logic of the gastric motility index is as follows: obtain the gastric motility speed at the current moment and the gastric motility speed at the previous moment in the stomach during the monitoring period, subtract the gastric motility speed at the current moment from the gastric motility speed at the previous moment to obtain the gastric motility speed difference, obtain the gastric motility speed at multiple time points during the monitoring period, calculate the average gastric motility speed, divide the gastric motility speed difference by the monitoring time to obtain the gastric motility speed decrease rate, and multiply the gastric motility speed decrease rate by the average gastric motility speed to obtain the gastric motility index.

[0060] The calculation logic of the pH index is as follows: obtain the current pH value and the previous pH value in the stomach during the monitoring period, subtract the current pH value from the previous pH value to obtain the pH difference, obtain the pH values ​​at multiple time points during the monitoring period, calculate the average pH value, divide the pH difference by the previous monitoring value to obtain the pH decrease rate, and multiply the pH decrease rate by the average pH value to obtain the pH index.

[0061] There is a certain relationship between the values ​​of temperature index, gastric motility index and pH index and the volume of the gastric capsule expansion. They mainly reflect the changes in the gastric environment, which may be caused by the changes in the volume of the gastric capsule expansion. The following is the possible relationship between each rate and the capsule expansion volume:

[0062] 1) Relationship between temperature index and expansion volume of stomach capsule: When the expansion volume of stomach capsule increases, the contact area between the capsule and the inner wall of the stomach increases, which may cause more friction or heat release, leading to an increase in temperature in the stomach. A capsule that expands too much may affect the circulation of gastric juice or the physical pressure on the stomach wall, thereby increasing the temperature in the stomach. If the temperature index is high, it means that the expansion volume of the capsule is too large, which may cause increased pressure and friction in the stomach, thereby accelerating the temperature rise. If the temperature index is too large, it means that the expansion volume of the capsule may be too large, and it is necessary to slow down the temperature index by reducing the expansion volume to avoid stomach discomfort.

[0063] 2) Relationship between gastric motility index and expanded volume of the stomach capsule: After the stomach capsule expands, the pressure on the stomach wall increases, which may lead to a decrease in the gastric motility. When the expanded volume is too large, the normal peristalsis of the stomach is suppressed, and the emptying rate of gastric juice and food may slow down, resulting in a decrease in gastric motility. If the gastric motility index is high, it means that the gastric motility function is impaired and the emptying capacity of the stomach is deteriorated, which is usually caused by excessive expansion of the stomach capsule. If the gastric motility index is large, the expanded volume of the capsule should be reduced to avoid long-term retention in the stomach and discomfort.

[0064] 3) Relationship between pH index and expanded volume of gastric capsule: A gastric capsule with a large expanded volume may increase gastric acid secretion or affect the circulation of gastric juice, leading to excessive gastric acid, thereby exacerbating the decrease in pH value in the stomach. Excessive expansion volume will lead to increased gastric acid concentration, which may aggravate the condition of excessive gastric acid. When the pH index is large, it means that the acidity in the stomach is too high, usually due to increased pressure in the stomach due to excessive expansion volume, or increased gastric juice secretion. If the pH index is large, it is necessary to reduce the expansion volume to avoid excessive stimulation of the stomach wall and increase in gastric acid concentration, thereby slowing down the rate of decrease in pH value.

[0065] Substituting the gastric status data into the intelligent regulation rule analysis includes the following steps:

[0066] The temperature index, gastric motility index and pH index are normalized so that their value ranges are mapped to [0,1], and the normalized value of the temperature index, the normalized value of the gastric motility index and the normalized value of the pH index are obtained. The normalized value of the temperature index minus the normalized value of the gastric motility index minus the normalized value of the pH index are summed to obtain the intragastric influencing factor.

[0067] The expansion volume of the stomach capsule is adjusted once, comprising the following steps:

[0068] The larger the value of the intragastric impact factor is, the worse the overall state of the user's stomach is, and the more it is necessary to reduce the expansion volume of the stomach capsule. After obtaining the intragastric impact factor, the initial expansion volume of the stomach capsule is adjusted once according to the intragastric impact factor. The adjustment algorithm expression is:

[0069] In the formula, volume one To adjust the expansion volume once, volume old is the initial expansion volume, effect is the influencing factor in the stomach, and the management system remotely controls the stomach capsule to adjust the expansion volume once through wireless technology (such as RFID or NFC technology, the capsule has a built-in low-power receiver that can receive wireless signals such as radio frequency identification (RFID) or near-field communication (NFC) signals).

[0070] After obtaining the intragastric state data and intragastric pressure at regular intervals, determining whether it is necessary to adjust the expansion volume of the stomach-occupying capsule for a second time includes the following steps:

[0071] Obtain the intragastric influencing factor and intragastric pressure regularly, first calculate and obtain the intragastric pressure fluctuation amplitude, and then comprehensively calculate the intragastric influencing factor and the intragastric pressure fluctuation amplitude to obtain the adjustment coefficient, the expression is: adjust = ω1 × effect + ω2 × pressure, where adjust is the adjustment coefficient, effect is the intragastric influencing factor, pressure is the intragastric pressure fluctuation amplitude, ω1 and ω2 are the weights of the intragastric influencing factor and the intragastric pressure fluctuation amplitude respectively, and 0<ω1<ω2<1;

[0072] The larger the adjustment coefficient, the more it is necessary to adjust the expansion volume of the Zhanwei capsule for the second time. The obtained adjustment coefficient is compared with the preset adjustment threshold. The adjustment threshold is used to determine whether it is necessary to adjust the expansion volume of the Zhanwei capsule for the second time. If the adjustment coefficient is less than the adjustment threshold, it is determined that it is not necessary to adjust the expansion volume of the Zhanwei capsule for the second time. If the adjustment coefficient is greater than or equal to the adjustment threshold, it is determined that it is necessary to adjust the expansion volume of the Zhanwei capsule for the second time.

[0073] The calculation logic of the intragastric pressure fluctuation amplitude is as follows: after obtaining the intragastric pressure values ​​at multiple time points, the intragastric pressure values ​​at multiple time points are set up, the average pressure value and the pressure value standard deviation in the set are calculated, and the intragastric pressure fluctuation amplitude is calculated. The expression is: In the formula, μ is the average pressure value, σ is the standard deviation of the pressure value, and the larger the value of the intragastric pressure fluctuation amplitude is, the greater the pressure in the stomach is rising as a whole during the monitoring period, and the smaller the expansion volume of the gastric capsule needs to be.

[0074] Generate a corresponding control strategy based on the judgment result, including the following steps:

[0075] When it is determined that the expansion volume of the Zhanwei capsule does not need to be adjusted twice, the management system controls the Zhanwei capsule to adjust the expansion volume once. When it is determined that the expansion volume of the Zhanwei capsule needs to be adjusted twice, the management system adjusts the expansion volume of the Zhanwei capsule twice through the adjustment coefficient. The expression is:

[0076] volume two =volume one / ln(adjust+1), in the formula, volume one To adjust the expansion volume once, volume two is the secondary adjustment of expansion volume, and adjust is the adjustment coefficient.

[0077] Embodiment 3: The intelligent satiety management system of the stomach-sucking capsule described in this embodiment includes an information acquisition module, an adjustment module, and a strategy generation module;

[0078] Information acquisition module: obtains stomach capsule information through stomach capsule control platform, the stomach capsule information includes stomach capsule initial expansion volume and stomach capsule model (usually doctors or professionals will recommend suitable capsule model and initial expansion volume according to the user's stomach capacity, health status and eating habits), and sends the stomach capsule information to the adjustment module;

[0079] Adjustment module: After the stomach-sucking capsule has been in the user's stomach for a period of time, the stomach status data is collected through the built-in sensor of the stomach-sucking capsule, the stomach status data is substituted into the intelligent adjustment rule analysis, and the expansion volume of the stomach-sucking capsule is adjusted once, and the expanded volume after the adjustment is sent to the strategy generation module;

[0080] Strategy generation module: after regularly acquiring the intragastric status data and intragastric pressure, it determines whether it is necessary to adjust the expansion volume of the stomach-occupying capsule for the second time, and generates a corresponding control strategy based on the judgment result.
