Description

Technical Field

[0001] The present invention relates to the field of medical rehabilitation technology, and in particular to a pelvic floor muscle rehabilitation system after rectal cancer anal preservation surgery based on an artificial expansion balloon. Background Art

[0002] After anal preservation surgery for rectal cancer, patients often experience sphincter dysfunction, such as decreased bowel control ability, requiring sphincter rehabilitation training to ensure a normal life for the patient. According to relevant technologies, rehabilitation training for patients is usually guided by doctors, who assess the patient's recovery status based on experience. Human assessments are somewhat accidental, leading to inaccurate sphincter recovery assessments and low rehabilitation training efficiency. This makes it difficult to accurately assess the patient's recovery status and formulate a plan for the next rehabilitation training session based on the patient's recovery status, resulting in insufficiently targeted rehabilitation training.

The patient's recovery status can be determined based on the patient's strength and control status, and a training plan for the next rehabilitation training session can be formulated based on the recovery status. This reduces reliance on doctors, improves the accuracy of patient recovery status assessments, and enhances the efficiency of patient rehabilitation training. A controller can send a first prompt message to the patient, control the valve to open the first branch, disconnect the second branch, and control the liquid pump to pump a first volume of liquid into the balloon. Subsequently, the valve is controlled to disconnect the first branch, open the second branch, and collect liquid pressure data, thereby sending a training prompt message to the patient and initiating training, providing basic data for determining the patient's recovery status. When determining the force condition coefficient, the force training condition coefficient can be determined by testing the patient's force generation and maintenance capabilities, accurately and comprehensively describing the recovery status of the sphincter's force generation ability and improving the accuracy and objectivity of the force training condition coefficient. The force condition coefficient and control condition coefficient can be determined based on the force training target data, control training target data, and liquid pressure data, thereby determining the rehabilitation status information of the patient undergoing this rehabilitation training, and determining the patient's rehabilitation status information from the two aspects of force and control.

Furthermore, based on the patient's rehabilitation status information, the strength training target data adjustment coefficient, the first control training target data adjustment coefficient and the second control training target data adjustment coefficient can be obtained, thereby obtaining the adjusted control training target data and the adjusted strength training target data, and then generating a training reminder message for the next rehabilitation training. Taking into account the situation where the adjustment coefficient is too large or too small, the above-mentioned adjustment coefficients are adjusted, thereby improving the matching degree between the adjusted training difficulty and the patient's recovery status, improving the accuracy of the patient's rehabilitation status assessment, and improving the efficiency of the patient's rehabilitation training.

Obviously, the described embodiments are only 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 making creative efforts shall fall within the scope of protection of the present invention.

[0065] The technical solution of the present invention is described in detail below with reference to specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0066] Figure 1 A schematic diagram of a pelvic floor muscle rehabilitation system after rectal cancer anal preservation surgery based on an artificial expansion balloon according to an embodiment of the present invention is exemplarily shown. The system includes:

[0067] Balloon, liquid pump, controller, pipe, pressure sensor, valve;

[0068] The liquid pump is connected to the balloon through the first branch of the pipeline and is used to pump liquid into the balloon;

[0069] The pressure sensor is connected to the balloon through the second branch of the pipeline and is used to detect liquid pressure data;

[0070] The valve is used to switch the first branch and the second branch;

[0071] The balloon is placed into the patient's rectum;

[0072] The controller is used to:

[0073] The patient is given a first prompt message to relax the sphincter;

[0074] Controlling the valve to open the first branch, disconnecting the second branch, and controlling the liquid pump to pump a first volume of liquid into the balloon;

[0075] The control valve disconnects the first branch and opens the second branch;

[0076] Send training reminder messages to patients;

[0077] determining the patient's recovery status information based on the training reminder message and the liquid pressure data detected after the training reminder message is issued;

[0078] Determine the training reminder message for the next rehabilitation training based on the patient's rehabilitation status information.

[0079] According to an embodiment of the present invention, the pelvic floor muscle rehabilitation system based on an artificial expansion balloon after rectal cancer anal preservation surgery can send a first prompt message to the patient to relax the sphincter. After the control valve opens the first branch and disconnects the second branch, and the liquid pump is controlled to pump a first volume of liquid into the balloon, the control valve disconnects the first branch and opens the second branch, and a training prompt message is sent to the patient. The liquid pressure data is detected to determine the patient's recovery status information, and then determine the training prompt message for the next rehabilitation training. The patient's recovery status can be determined based on the patient's strength status and control status, and a training plan for the next rehabilitation training can be formulated based on the recovery status, reducing dependence on doctors, improving the accuracy of the patient's recovery status assessment, and improving the efficiency of the patient's rehabilitation training.

[0080] According to an embodiment of the present invention, a liquid pump is connected to the balloon via a first branch of a conduit. After the balloon is placed in the patient's rectum, the liquid pump can pump liquid into the balloon. The pumped liquid can be a sterile liquid such as water or saline. Based on signals sent by a controller, a specified volume of liquid is pumped out and then enters the balloon through the first branch for use in patient rehabilitation training.

[0081] According to an embodiment of the present invention, a pressure sensor is connected to the balloon via a second branch of the pipeline for detecting liquid pressure data. The pressure sensor (e.g., a MEMS piezoresistive sensor, a capacitive sensor, etc.), the second branch, and the balloon can form a sealed communication vessel. During rehabilitation training, the liquid pressure within the balloon can be transmitted to the pressure sensor via the second branch, thereby detecting the liquid pressure value, which is the liquid pressure data. Of course, the pressure sensor can display the liquid pressure data in real time or remotely connect to the patient's mobile device to display the pressure data on the mobile device, allowing the patient to observe in real time during rehabilitation training whether their application of force has achieved the target liquid pressure data as indicated in the training prompt message.

[0082] According to an embodiment of the present invention, a valve is used to switch between a first branch and a second branch. The valve can switch between the first branch and the second branch based on a signal from a controller. When the valve switches to the first branch, the second branch is disconnected, preventing the transmission of liquid pressure data to the pressure sensor. When the valve switches to the second branch, the first branch is disconnected, preventing the pumping of liquid into the balloon. This prevents pressure from being transmitted to the liquid pump through the first branch when the patient exerts force.

[0083] According to an embodiment of the present invention, the balloon is placed in the patient's rectum. During rehabilitation training, the patient's sphincter squeezes the balloon, increasing the pressure of the liquid inside the balloon. This allows the liquid pressure data to be measured and the force exerted by the patient's sphincter to be determined. The better the patient's recovery, the more liquid can be pumped into the balloon, increasing the balloon's resistance and thus increasing the difficulty of the rehabilitation training. Conversely, less liquid can be pumped into the balloon to reduce the difficulty of the rehabilitation training. Based on the above-mentioned processing method, the difficulty of rehabilitation training can be gradually increased, thereby improving the efficiency of rehabilitation training.

[0084] According to an embodiment of the present invention, the controller is configured to send a first prompting message to the patient to relax their sphincter muscles. This prompting message, i.e., the first prompting message, can be displayed on a mobile phone screen, played through a loudspeaker, or other means, prompting the patient to prepare for pumping fluid into the balloon. For example, the controller can send a first prompting message, "Please relax," via a text message to the mobile phone of a patient undergoing rehabilitation training. The patient is instructed to relax their sphincter muscles upon receiving the first prompting message.

[0085] According to an embodiment of the present invention, a control valve opens the first branch, disconnects the second branch, and controls the liquid pump to pump a first volume of liquid into the balloon. Because patients undergoing rehabilitation training often have weak sphincter control, the first branch can be opened, the second branch disconnected, and the liquid pump controlled to pump a first volume of liquid into the balloon five seconds after the first prompt message is issued, allowing the patient sufficient time to relax their sphincter. The first volume can be determined based on the patient's recovery status. When the patient's recovery status is good, a larger first volume (e.g., 15 ml) can be set to increase the resistance of the balloon and thus increase the difficulty of rehabilitation training. Conversely, a smaller first volume (e.g., 5 ml) can be set to reduce the difficulty of rehabilitation training. The present invention does not impose any restrictions on this.

[0086] According to an embodiment of the present invention, the control valve disconnects the first branch and opens the second branch. After the liquid pump is controlled to pump a first volume of liquid into the balloon, the first branch is disconnected to prevent pressure from being transmitted to the liquid pump through the first branch when the patient exerts force. The second branch is opened to transmit the pressure of the liquid in the balloon to the pressure sensor through the second branch when the patient exerts force.

[0087] According to an embodiment of the present invention, a training reminder message is sent to the patient. The training reminder message can be sent to the patient in the same manner as the first reminder message. For example, a training reminder message such as "Please use force to reach the liquid pressure of 40 mmHg, please apply force slowly for 5 seconds to reach 20 mmHg" can be sent to the mobile phone of the patient undergoing rehabilitation training via a controller in the form of a text message. After receiving the training message, the patient must control the sphincter force as required.

[0088] In this way, the controller can send a first prompt message to the patient, control the valve to open the first branch, disconnect the second branch, and control the liquid pump to pump a first volume of liquid into the balloon. Then, the valve is controlled to disconnect the first branch and open the second branch, and the liquid pressure data is collected, so as to send a training prompt message to the patient and start training, providing basic data for determining the patient's recovery status information.

[0089] According to an embodiment of the present invention, the patient's recovery status information is determined based on the training prompt message and the liquid pressure data detected after the training prompt message is issued, including: determining the strength training target data and the control training target data based on the training prompt message; determining the strength status coefficient based on the strength training target data and the liquid pressure data; determining the control status coefficient based on the control training target data and the liquid pressure data; and determining the patient's recovery status information based on the strength status coefficient and the control status coefficient.

[0090] According to an embodiment of the present invention, the strength training target data and the control training target data are determined based on the training prompt message. In the training prompt message, the target pressure that the patient needs to reach is the strength training data. For example, the training prompt message is "Please exert force to reach 40mmHg", and the strength training target data is 40mmHg. The control training target data may include the target pressure that the patient needs to reach during control training and the time required to reach the target pressure. The target pressure that the patient needs to reach during control training is, for example, "Please exert force slowly for 5 seconds to reach 20mmHg", and the target pressure that the patient needs to reach during control training is 20mmHg, and the time required to reach the target pressure is 5 seconds. Since the strength training target data is mainly for training the patient's ability to exert force, and the control target training data is mainly for training the patient's ability to control force, the target pressure in the control target data is smaller than the strength training target data.

[0091] According to an embodiment of the present invention, a force condition coefficient is determined based on force training target data and liquid pressure data, including: obtaining liquid pressure data at multiple moments within a first preset time period after the moment of issuing a training prompt message; determining a first maximum value of the liquid pressure data, and a first moment corresponding to the first maximum value of the liquid pressure data; determining a first minimum value and a first average value of the liquid pressure data at multiple moments in a time period between the first moment and the end moment of the first preset time period; and determining a force condition coefficient based on the first maximum value, the first minimum value, the first average value and the force training target data.

[0092] According to an embodiment of the present invention, liquid pressure data is acquired at multiple moments within the first preset time period after the moment the training reminder message is sent. After receiving the training reminder message, the patient starts to exert force and tries to reach the strength training target data as much as possible. The patient may be required to exert force and maintain it for a certain period of time, i.e., the first preset time period, for example, 3 seconds. When acquiring liquid pressure data at multiple moments within the first preset time period, the time interval between adjacent moments may be 0.1 seconds. Sufficient liquid pressure data may be collected within the first preset time period to determine the patient's strength condition coefficient. The maximum value of the liquid pressure data at each moment collected within the first preset time period is the first maximum value. The moment corresponding to the liquid pressure data reaching the maximum value is the first moment. The minimum value of the liquid pressure data at multiple moments in the time period between the first moment and the end moment of the first preset time period is the first minimum value. The average value of the liquid pressure data corresponding to all moments in the time period between the first moment and the end moment of the first preset time period is the first average value.

[0093] According to an embodiment of the present invention, according to an embodiment of the present invention, determining a force condition coefficient according to the first maximum value, the first minimum value, the first average value and the force training target data includes: determining the force condition coefficient according to formula (1): , (1),

[0094] in, is the first maximum value, is the first average value, is the first minimum value, is the strength training target data, is the end time of the first preset time period, is the first moment, is the duration of the first preset time period, is a coefficient less than 1 and greater than 0, The first time after the first moment, the data is less than The moment corresponding to the liquid pressure data.

[0095] According to an embodiment of the present invention, since the first maximum value of the patient in the first preset time period can reach the strength training target data (that is, the patient's force generation ability can reach the target force generation ability) under good recovery conditions, and can be maintained until the end of the first preset time period, under normal circumstances, the first maximum value, the first minimum value and the first average value should all be greater than or equal to the strength training target data, that is, the patient's force generation ability should always reach the target force generation ability in strength training. If the recovery condition is not good, the first maximum value may not reach the strength training target data or it may be difficult to maintain the strength after briefly reaching the strength training target data, resulting in a lower first minimum value and first average value after the first moment. Therefore, in formula (1), The ratio information representing the first maximum value and the strength training target data can describe the patient's force-generating ability under the optimal force-generating condition during strength training. The ratio information representing the first average value and the strength training target data can describe the patient's ability to maintain strength during strength training. The information representing the ratio of the first minimum value to the strength training target data can describe the patient's ability to exert force under the worst conditions when maintaining a large force (i.e., the ability to exert force when it cannot be maintained). It can represent the patient's overall force-generating ability in strength training, can be used as proportional information to evaluate the patient's force-generating ability, and can describe the patient's force-generating ability demonstrated in strength training.

[0096] According to an embodiment of the present invention, in formula (1), after the patient's force reaches the first maximum value, it may not be possible to always maintain the maximum force state during the process of maintaining a large force. The liquid pressure data will gradually decrease and will not decrease to 0 instantly. Therefore, It can represent the target pressure in strength training when the patient reaches the first maximum force and maintains a large force (that is, the minimum liquid pressure data required to maintain force under normal circumstances). It can be considered as the target maintenance pressure. For manually set experience values, for example, .when When , it means that after the patient reaches the first maximum force, in the process of maintaining the force, although the force gradually decreases, the force at each moment can reach or exceed the target maintenance pressure. It can be considered that the patient has maintained the force. Therefore, in formula (1), The duration between the end of the first preset time period and the first moment can be considered as the duration of maintaining the force under the condition of maintaining the force. The ratio of the duration of maintaining the force to the first preset time period can indicate the ability to reach the maximum force and maintain the force.

[0097] According to an embodiment of the present invention, in formula (1), when When the first minimum value is less than the target maintenance pressure, the patient's force gradually decreases during the process of maintaining the force after reaching the first maximum value, and the target maintenance pressure cannot be reached after a certain moment. It can be considered that the force is not maintained. Therefore, in formula (1), Indicates that the first time after the first moment, the The time length between the moment corresponding to the liquid pressure data and the first moment, since the patient cannot continue to maintain the force during the time period from the moment when the patient cannot maintain the force to the end time of the first preset time period, therefore, is the length of time the patient can maintain force, so The ratio of the duration of the force maintenance to the first preset time period can describe the patient's ability to maintain strength during strength training. The product of the proportional information used to assess the patient's ability to sustain force and the proportional information used to assess the patient's force generation capacity can be used as a force condition coefficient, which comprehensively describes the patient's sphincter force generation capacity from the perspectives of both force generation and maintenance. The larger the force condition coefficient, the stronger the patient's sphincter force generation and maintenance capacity demonstrated during this strength training. Conversely, the smaller the force condition coefficient, the worse the patient's sphincter force generation and maintenance capacity demonstrated during this strength training.

[0098] In this way, the strength training condition coefficient can be determined by testing the patient's force generation ability and maintenance ability, accurately and comprehensively describing the recovery status of the sphincter's force generation ability, and improving the accuracy and objectivity of the strength training condition coefficient.

[0099] According to an embodiment of the present invention, the training prompt message includes a frequency control training prompt message and a maintenance control training prompt message; the control status coefficient is determined based on the control training target data and the liquid pressure data, including: determining the second moment at which the frequency control training prompt message is issued each time, and the third moment at which the liquid pressure data is detected to be higher than the detection threshold in the time period between two adjacent second moments; detecting the liquid pressure data at multiple moments within the action time period after the maintenance control training prompt message is issued; determining the control status coefficient based on the second moment, the third moment, the liquid pressure data within the action time period and the control training target data.

[0100] According to an embodiment of the present invention, the frequency control training prompt message may be multiple training prompt messages, prompting the patient to perform frequency control training. For example, a training prompt message "Please push harder" sent to the patient every 2 seconds is a frequency control message. The hold control training prompt message may prompt the patient to perform hold control training, for example, "Please push slowly for 5 seconds to reach 20 mmHg." The moment each frequency control training prompt message is sent is the second moment. The detection threshold is the minimum fluid pressure data required for effective sphincter exertion under normal circumstances. When the fluid pressure data is less than the detection threshold, the patient's force is too weak to effectively control sphincter exertion, and the patient is considered to have failed the training. Conversely, when the fluid pressure data is greater than or equal to the detection threshold, the patient's force is effective, and the patient is considered to have successfully exerted force, completing a frequency control training session. The moment when the fluid pressure data is detected to be above the detection threshold in the time period between two adjacent second moments is the third moment (i.e., the moment when the patient successfully exerted force). Furthermore, within the action time period after the maintenance control training prompt message is issued, the liquid pressure data at multiple moments are detected. When the liquid pressure data at multiple moments within the time period are detected, the time interval between adjacent moments may be 0.1 seconds.

[0101] According to an embodiment of the present invention, the control state coefficient is determined based on the liquid pressure data and the control training target data within the second moment, the third moment, and the action time period, including: determining a preset reaction time according to the control training target data; determining the control training force data and the duration of the action time period according to the control training target data; and determining the control state coefficient according to formula (2): , (2),

[0102] in, To preset the reaction time, is the second moment when the frequency control training prompt message is issued for the i-th time, is the third moment between the second moment when the frequency control training prompt message is sent for the i-th time and the second moment when the frequency control training prompt message is sent for the (i+1)th time. The second moment when the frequency control training prompt message is sent for the i+1th time, The moment before the second moment when the frequency control training prompt message is sent for the (i+1)th time, is the liquid pressure data detected at time t, is the detection threshold, max is the maximum value function, n is the number of frequency control training prompt messages, i≤n, is the kth moment in the action time period corresponding to the sth hold control training prompt message, The k+1th moment in the action time period corresponding to the sth hold control training prompt message, The control training intensity data corresponding to the s-th control training prompt message, The control training intensity data corresponding to the s-1th control training prompt message. When s=1, , is the duration of the action time period corresponding to the s-th hold control training prompt message, for Liquid pressure data detected at all times, for Liquid pressure data detected at all times, is the number of moments in the action time period corresponding to the s-th maintenance control training prompt message, N is the number of maintenance control training prompt messages, k≤ , s≤N, and i, n, k, , s, and N are all positive integers.

[0103] According to an embodiment of the present invention, the preset reaction time is determined based on the control training target data. The target time between the moment when the patient receives the frequency control training prompt message and the moment when the force required by the training causes the liquid pressure data to reach the detection threshold (that is, the reaction time required for successful force under normal circumstances) is the preset reaction time, for example, 0.5 seconds. According to the control training target data, the control training force data and the duration of the action time period are determined. In the control training target data, the target pressure that the patient needs to reach is the control training force data, and the target duration that the patient needs to exert force is the duration of the action time period. For example, the control training target data is to slowly exert force for 5 seconds to reach 20 mmHg, the control training force data is 20 mmHg, and the duration of the action time period is 5 seconds.

[0104] According to an embodiment of the present invention, in formula (2), Indicates the variable between the control training strength data corresponding to the sth and s-1th control training prompt messages (when s=1, ),therefore, The ratio of the variable representing the control training force data to the duration of the action period corresponding to the s-th control training reminder message can be considered as the target change speed of the control training force data corresponding to the s-th control training reminder message. Since under normal circumstances, the change speed at each moment in the action period corresponding to the s-th control training reminder message is the same (i.e., uniform force), therefore, It can be used as the target change speed in the time period between each moment in the action time period corresponding to the s-th maintenance control training prompt message. It can represent the actual change rate of the liquid pressure data between the kth moment and the k+1th moment within the action time period corresponding to the sth maintenance control training prompt message.

[0105] According to an embodiment of the present invention, when When the target change speed is in the same direction as the actual change speed, the patient's force direction is correct, but the force change speed may be different from the target change speed. It can represent the relative difference between the target change speed and the actual change speed between the kth moment and the k+1th moment in the action time period corresponding to the sth hold control training prompt message, and the difference between 1 and the above relative difference , which can be used to evaluate the patient's ability to maintain control at that moment and can describe the patient's ability to maintain control.

[0106] According to an embodiment of the present invention, when When the actual change speed is 0 or the target change speed is opposite to the actual change speed, the patient's force direction does not meet the requirements of this maintenance control training. The corresponding value for evaluating the patient's ability to maintain control at this moment is 0. For example, the reminder message for maintenance control training is "Please slowly exert force for 5 seconds to reach 20mmHg". The patient does not exert force or the force gradually decreases. The force does not meet the requirements of maintenance control training. The corresponding value for evaluating the patient's ability to maintain control is 0. Therefore, It can represent the average value of the control ability at each moment in the action time period corresponding to the s-th control training prompt message, and can represent the patient's control ability during the training for the control training prompt message. It can describe the patient's ability to maintain control during training for multiple maintenance control training prompt messages. The larger the value is, the stronger the patient's ability to maintain control during control training is.

[0107] According to an embodiment of the present invention, in formula (2), It represents the maximum value of the liquid pressure data detected at multiple moments between the second moment when the frequency control training prompt message is sent for the i-th time and the i+1-th time. The patient's force gradually increases. The maximum value of the patient's force between the second moment when the frequency control training prompt message is sent for the i-th time and the i+1-th time is the patient's maximum force during the i-th frequency control training. This maximum force can be used to determine whether the patient's force ability meets the standard, that is, to determine whether the patient has successfully exerted force during the i-th frequency control training. If the force is successfully exerted, the subsequent reaction time calculation is performed to determine the patient's reaction speed and frequency control ability. If the force is not successfully exerted, it means that the patient cannot effectively control the sphincter. When the patient cannot effectively control the sphincter force, it can be considered that the patient cannot respond to the training prompt message, so the piecewise function value can be directly set to 0. When When the maximum value is greater than or equal to the detection threshold, the patient successfully exerts force in the i-th frequency control training and completes the i-th frequency control training. On the contrary, when When , the maximum value is less than the detection threshold, the patient's force in the i-th frequency control training is too small to effectively control the sphincter force, and it can be considered that the patient has failed to exert force.

[0108] According to an embodiment of the present invention, in formula (2), when When the patient exerts force successfully, in this case, The time duration between the third moment between the second moment of the frequency control training reminder message being sent for the i+1th time and the second moment of the frequency control training reminder message being sent for the i-th time can be considered as the actual reaction time of the patient to successfully exert force in the i-th frequency control training (i.e., the actual time duration from the patient receiving the frequency control training reminder message to the patient successfully exerting force, which can also represent the patient's reaction speed). Therefore, The ratio information of the preset reaction time to the actual reaction time can be considered as the ratio information for evaluating the frequency control ability this time, and can describe the patient's frequency control ability.

[0109] According to an embodiment of the present invention, when When the patient fails to exert force, the patient's frequency control ability corresponding to the frequency control training prompt message sent by the patient for the i-th time is 0, and it can be considered that the patient has not completed this frequency control training. It represents the average value of the assessed frequency control ability corresponding to each frequency control training reminder message, which can describe the frequency control ability of the patient in this frequency control training. The larger the average value, the stronger the frequency control ability of the patient in this control training.

[0110] According to an embodiment of the present invention, the product of the above two items can be used as the patient's control condition coefficient The control coefficient can be used to comprehensively describe the patient's ability to control the sphincter from the perspectives of both maintenance control and frequency control. The larger the control coefficient, the stronger the patient's ability to control the sphincter during this control training. Conversely, the smaller the control coefficient, the worse the patient's ability to control the sphincter during this control training.

[0111] According to an embodiment of the present invention, the patient's rehabilitation status information is determined based on the force condition coefficient and the control condition coefficient. The rehabilitation status information may include the force condition coefficient and the control condition coefficient corresponding to the patient's current rehabilitation training. For example, if the force condition coefficient and the control condition coefficient corresponding to the patient's current rehabilitation training are 0.5 and 0.7, respectively, the rehabilitation status information is "the force condition coefficient is 0.5, and the control condition coefficient is 0.7."

[0112] In this way, the force condition coefficient and control condition coefficient can be determined based on the force training target data, control training target data, and fluid pressure data, thereby determining the patient's recovery status information for this rehabilitation training session. This information is determined from both the force and control aspects. This considers that the force condition coefficient includes both force generation and maintenance capabilities, and that the control condition coefficient includes both frequency control and maintenance control capabilities. This improves the accuracy, comprehensiveness, and objectivity of the force condition coefficient, control condition coefficient, and patient recovery status information.

[0113] According to an embodiment of the present invention, a training prompt message for the next rehabilitation training is determined based on the patient's rehabilitation status information, including: when the strength condition coefficient is higher than or equal to the first strength coefficient threshold, or lower than the second strength coefficient threshold, determining the strength training target data adjustment coefficient according to formula (3) , (3),

[0114] in, is the force condition coefficient, is a coefficient less than 1 and greater than 0, is the first force coefficient threshold, is a coefficient greater than 1, is the second force coefficient threshold, ; Adjust the strength training target data according to the strength training target data adjustment coefficient to obtain the adjusted strength training target data; when the control condition coefficient is higher than or equal to the first control coefficient threshold, or lower than the second control coefficient threshold, determine the first control training target data adjustment coefficient according to formula (4) , (4),

[0115] in, is the control condition coefficient, is the first control coefficient threshold, is the second control coefficient threshold, , and is a coefficient less than 1 and greater than 0; the second control training target data adjustment coefficient is determined according to formula (5) , (5),

[0116] Among them, the second control training target data adjustment coefficient is used to adjust the variance of the control training target data; according to the first control training target data adjustment coefficient and the second control training target data adjustment coefficient, the control training target data is adjusted to obtain the adjusted control training target data; according to the adjusted control training target data and the adjusted strength training target data, a training reminder message for the next rehabilitation training is obtained.

[0117] According to an embodiment of the present invention, in formula (3), when When the strength condition coefficient is higher than or equal to the first strength coefficient threshold (for example, 0.8), the patient's sphincter strength ability in this rehabilitation training is very good. The strength training difficulty in the current rehabilitation training is too simple for the patient and cannot achieve the training effect. Since the larger the strength training data, the greater the difficulty of strength training, the strength training target data can be increased to increase the difficulty of strength training. On the contrary, when When the strength condition coefficient is lower than the second strength coefficient threshold (for example, 0.3), the patient's sphincter force ability shown in this rehabilitation training is very poor. The strength training difficulty in the current rehabilitation training is too difficult for the patient and he cannot complete the training. Therefore, the strength training target data can be reduced to reduce the difficulty of strength training.

[0118] According to an embodiment of the present invention, in formula (3), when hour, It represents the difference between the strength condition coefficient and the first strength coefficient threshold, which can describe the gap between the patient's strength training result and the training target. It can be used as an increase coefficient for the target strength condition coefficient, or as an increase coefficient for the strength training target data. is a coefficient less than 1 and greater than 0, so it can be obtained by The increase coefficient of the strength training target data is reduced and adjusted to obtain the adjusted increase coefficient of the strength training target data. Based on the above processing method, the increase coefficient of the strength training target data can be kept within a reasonable range, reducing the possibility that the patient cannot reach the adjusted strength training target data due to an excessively large increase coefficient. When the patient can complete the training, the difficulty of the strength training is increased, thereby obtaining the adjustment coefficient of the strength training target data. . Similarly, when When Reduction coefficient for strength training target data Make an increase adjustment to obtain the reduction coefficient of the adjusted strength training target data, so as to reduce the difficulty of strength training and enable the patient to complete strength training, and then obtain the strength training target data adjustment coefficient .

[0119] According to an embodiment of the present invention, the force training target data is adjusted according to the force training target data adjustment coefficient to obtain the adjusted force training target data. This adjusts the difficulty of the force training, thereby improving the effectiveness of the rehabilitation training while enabling the patient to complete the training. For example, if the force training target data for this rehabilitation training is 20 mmHg and the force training target data adjustment coefficient is 1.1, the adjusted force training target data is the product of 20 and 1.1, i.e., 22 mmHg.

[0120] According to an embodiment of the present invention, in formula (4), when When the control condition coefficient is higher than or equal to the first control coefficient threshold (for example, 0.8), the patient's sphincter control ability in this control training is very good. The control training difficulty in the current rehabilitation training is too simple for the patient and cannot achieve the training effect. Since the shorter the preset reaction time, the greater the difficulty of the control training, the preset reaction time can be shortened to increase the difficulty of the control training. On the contrary, when When the control status coefficient is lower than the second control coefficient threshold (for example, 0.3), the patient's sphincter control ability shown in this rehabilitation training is very poor. The control training difficulty in the current rehabilitation training is too difficult for the patient to complete the training. Therefore, the preset reaction time can be extended to reduce the difficulty of the control training and ensure that the patient completes the rehabilitation training.

[0121] According to an embodiment of the present invention, similar to formula (3), Can be used as a shortening factor for preset reaction time, because and is a coefficient less than 1 and greater than 0, so it can be obtained by The shortening coefficient of the preset reaction time is adjusted to obtain the adjusted shortening coefficient Based on the above processing method, the shortening coefficient of the preset reaction time can be kept within a reasonable range, reducing the possibility that the patient cannot reach the adjusted preset reaction time and action time period due to the shortening coefficient being too large. When the patient can complete the training, the effect of rehabilitation training is improved, and the first control training target data adjustment coefficient can be obtained. . Similarly, you can Extension factor for the preset reaction time Adjustments are made to reduce the possibility that the preset reaction time is too long due to the extension coefficient being too large, the control training difficulty is too simple for the patient, and the training effect cannot be achieved, thereby obtaining the first control training target data adjustment coefficient The first control training target data adjustment coefficient can be used to adjust the preset reaction time in multiple training sessions.

[0122] According to an embodiment of the present invention, in formula (5), the second control training target data adjustment coefficient is used to adjust the variance of the control training target data in the maintenance control training (the variance of the control training intensity data and the duration of the action time period in the multiple maintenance control training prompt messages. The higher the variance, the greater the data difference between the control training intensity data and the duration of the action time period, and the more difficult it is to perform maintenance control). Since the variance in the control training target data is larger, the fluctuation of the control training target data is larger, the more difficult it is to control, and the greater the difficulty of control training. Similar to formula (4), when When , the control training difficulty in the current rehabilitation training is too simple for the patient and cannot achieve the training effect. The variance of the control training target data can be increased to increase the difficulty of the control training and improve the effect of rehabilitation training. On the contrary, when When the control training difficulty in the current rehabilitation training is too difficult for the patient to complete the training, the variance of the control training target data can be reduced to reduce the difficulty of the control training and ensure that the patient completes the rehabilitation training.

[0123] According to an embodiment of the present invention, similar to formula (3), when hour, It can represent the second control training target data adjustment coefficient, which can be obtained by The increase coefficient of the variance of the control training target data is adjusted to reduce the possibility that the patient will complete the adjusted maintenance control training due to the excessive increase coefficient. When the patient can complete the training, the effect of rehabilitation training is improved. On the contrary, when hour, It can represent the second control training target data adjustment coefficient, which can be obtained by The reduction coefficient of the variance of the control training target data is adjusted to be smaller to reduce the possibility that the variance of the control training target data is too small due to the reduction coefficient being too large, and the control training difficulty is too simple for the patient, thereby reducing the possibility that the training effect cannot be achieved.

[0124] According to an embodiment of the present invention, the control training target data is adjusted based on a first control training target data adjustment coefficient and a second control training target data adjustment coefficient to obtain adjusted control training target data. The product of the first control training target data adjustment coefficient and the preset reaction time is the adjusted preset reaction time, and the product of the second control training target data adjustment coefficient and the variance of the control training target data (control training force data and the duration of the action time period) is the adjusted variance of the control training target data. The control training target data is adjusted based on the adjusted preset reaction time and the adjusted variance of the control training target data to obtain the adjusted control training target data.

[0125] According to an embodiment of the present invention, a training reminder message for the next rehabilitation training session is obtained based on the adjusted control training target data and the adjusted strength training target data. Similar to the training reminder message generated for the current rehabilitation training session, the adjusted preset reaction time, the adjusted variance of the control training target data, and the adjusted strength training data can be determined based on the adjusted control training target data and the adjusted strength training target data, thereby generating a plan for the next rehabilitation training session and a training reminder message for the next rehabilitation training session, thereby making the difficulty of the next rehabilitation training session more suitable for the patient and improving the effectiveness of the next rehabilitation training session.

[0126] In this way, based on the patient's rehabilitation status information, the strength training target data adjustment coefficient, the first control training target data adjustment coefficient and the second control training target data adjustment coefficient can be obtained, thereby obtaining the adjusted control training target data and the adjusted strength training target data, and then generating a training reminder message for the next rehabilitation training. Taking into account the situation where the adjustment coefficient is too large or too small, the above-mentioned adjustment coefficients are adjusted, thereby improving the matching degree between the adjusted training difficulty and the patient's recovery status, improving the accuracy of the patient's rehabilitation status assessment, and improving the efficiency of the patient's rehabilitation training.

[0127] According to an embodiment of the present invention, a pelvic floor muscle rehabilitation system based on an artificially dilating balloon after rectal cancer anal preservation surgery can issue a first prompt message to the patient to relax the sphincter. After controlling a valve to open the first branch and disconnect the second branch, and controlling a liquid pump to pump a first volume of liquid into the balloon, the valve is controlled to disconnect the first branch and open the second branch, a training prompt message is issued to the patient, and liquid pressure data is detected to determine the patient's recovery status and, in turn, a training prompt message for the next rehabilitation training session. The system can determine the patient's recovery status based on the patient's strength and control status, and formulate a training plan for the next rehabilitation session based on the recovery status, reducing reliance on doctors, improving the accuracy of patient recovery status assessment, and enhancing the efficiency of patient rehabilitation training. A controller can issue a first prompt message to the patient, control the valve to open the first branch and disconnect the second branch, and control the liquid pump to pump a first volume of liquid into the balloon. Subsequently, the valve is controlled to disconnect the first branch and open the second branch, and liquid pressure data is collected to issue a training prompt message to the patient and initiate training, providing basic data for determining the patient's recovery status. When determining the force condition coefficient, the force training condition coefficient can be determined by testing the patient's force generation and maintenance capabilities, accurately and comprehensively describing the recovery status of the sphincter's force generation ability and improving the accuracy and objectivity of the force training condition coefficient. The force condition coefficient and control condition coefficient can be determined based on the force training target data, control training target data, and liquid pressure data, thereby determining the rehabilitation status information of the patient undergoing this rehabilitation training, and determining the patient's rehabilitation status information from the two aspects of force and control. Taking into account the fact that the force condition coefficient includes both force generation and maintenance capabilities, and taking into account the fact that the control condition coefficient includes both frequency control capabilities and maintenance control capabilities, the accuracy, comprehensiveness, and objectivity of the force condition coefficient, control condition coefficient, and patient rehabilitation status information are improved. Furthermore, based on the patient's rehabilitation status information, the strength training target data adjustment coefficient, the first control training target data adjustment coefficient and the second control training target data adjustment coefficient can be obtained, thereby obtaining the adjusted control training target data and the adjusted strength training target data, and then generating a training reminder message for the next rehabilitation training. Taking into account the situation where the adjustment coefficient is too large or too small, the above-mentioned adjustment coefficients are adjusted, thereby improving the matching degree between the adjusted training difficulty and the patient's recovery status, improving the accuracy of the patient's rehabilitation status assessment, and improving the efficiency of the patient's rehabilitation training.
