Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation technology, and in particular to a pelvic floor muscle rehabilitation system based on an artificial dilatation balloon after rectal cancer surgery with sphincter preservation. Background Technology

[0002] After rectal cancer surgery with sphincter preservation, patients often experience sphincter dysfunction, such as decreased bowel control. Rehabilitation training of the sphincter muscles is necessary to ensure a normal life. However, current techniques typically rely on physician guidance and experience-based assessments of the patient's recovery. This human assessment is inherently prone to error, leading to inaccurate evaluations of sphincter rehabilitation and inefficient training. It is difficult to accurately assess the patient's progress and tailor subsequent rehabilitation plans accordingly, resulting in insufficiently targeted rehabilitation training.

[0063] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0064] According to the present invention, a first prompt message to relax the sphincter muscles can be issued to the patient. After the control valve opens the first branch and closes the second branch, and the liquid pump pumps a first volume of liquid into the balloon, the control valve closes the first branch and opens the second branch, a training prompt message is issued to the patient, and liquid pressure data is detected to determine the patient's rehabilitation status information, thereby determining the training prompt message for the next rehabilitation training. The patient's rehabilitation status can be determined based on the patient's strength and control status, and a training plan for the next rehabilitation training can be formulated based on the rehabilitation status, reducing dependence on doctors, improving the accuracy of patient rehabilitation status assessment, and improving the efficiency of patient rehabilitation training. The controller can issue a first prompt message to the patient, control the valve to open the first branch and close the second branch, and control the liquid pump to pump a first volume of liquid into the balloon. Subsequently, the control valve closes the first branch and opens the second branch, collects liquid pressure data, and then issues a training prompt message to the patient to start training, providing basic data for determining the patient's rehabilitation status information. When determining the strength condition coefficient, the patient's ability to exert force and maintain it can be assessed to determine the strength training condition coefficient, accurately and comprehensively describing the recovery status of the sphincter's exertion ability and improving the accuracy and objectivity of the strength training condition coefficient. Furthermore, based on strength training target data, control training target data, and fluid pressure data, strength condition coefficients and control condition coefficients can be determined, thereby identifying the patient's rehabilitation status information from both strength and control perspectives. By considering that the strength condition coefficient includes both exertion and maintenance abilities, and that the control condition coefficient includes both frequency control and maintenance control abilities, the accuracy, comprehensiveness, and objectivity of determining the strength condition coefficient, control condition coefficient, and patient rehabilitation status information are improved. Furthermore, based on the patient's rehabilitation status information, adjustment coefficients for the intensity training target data, the first control training target data, and the second control training target data can be obtained, thus yielding adjusted control training target data and adjusted intensity training target data. This allows for the generation of training prompt messages for the next rehabilitation training session. Furthermore, considering cases where the adjustment coefficients are too large or too small, the aforementioned adjustment coefficients are adjusted, improving the match between the adjusted training difficulty and the patient's recovery status, enhancing the accuracy of patient rehabilitation status assessment, and increasing the efficiency of patient rehabilitation training.

[0070] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0071] Figure 1 An exemplary schematic diagram of a pelvic floor muscle rehabilitation system based on an artificial dilatation balloon after rectal cancer surgery with sphincter preservation, according to an embodiment of the present invention, is shown, the system comprising:

[0072] Balloons, liquid pumps, controllers, pipes, pressure sensors, valves;

[0073] The liquid pump is connected to the balloon via the first branch of the pipeline and is used to pump liquid into the balloon;

[0074] The pressure sensor is connected to the balloon via a second branch of the pipeline and is used to detect liquid pressure data;

[0075] The valve is used to switch between the first branch and the second branch;

[0076] The balloon is used to insert into the patient's rectum;

[0077] The controller is used for:

[0078] The first prompt message to the patient is to relax the sphincter muscles;

[0079] The control valve opens the first branch, disconnects the second branch, and controls the liquid pump to pump the first volume of liquid into the balloon;

[0080] The control valve disconnects the first branch and opens the second branch;

[0081] Send training prompt messages to patients;

[0082] Based on the training prompt message and the fluid pressure data detected after the training prompt message was issued, the patient's rehabilitation status information is determined;

[0083] Based on the patient's recovery status information, determine the training prompt message for the next rehabilitation training session.

[0084] According to an embodiment of the present invention, a pelvic floor muscle rehabilitation system based on an artificial dilatation balloon after rectal cancer surgery with sphincter preservation can issue a first prompt message to the patient to relax the sphincter muscles. After controlling the valve to open the first branch and disconnect the second branch, and controlling the liquid pump to pump a first volume of liquid into the balloon, the control valve disconnects the first branch and opens the second branch, issuing a training prompt message to the patient and detecting liquid pressure data to determine the patient's rehabilitation status information, thereby determining the training prompt message for the next rehabilitation training. The system can determine the patient's rehabilitation status based on the patient's strength and control status, and formulate a training plan for the next rehabilitation training based on the rehabilitation status, reducing reliance on doctors, improving the accuracy of patient rehabilitation status assessment, and enhancing the efficiency of patient rehabilitation training.

[0085] According to an embodiment of the present invention, a liquid pump is connected to a balloon via a first branch of a conduit. After the balloon is inserted into the patient's rectum, the liquid pump can pump liquid into the balloon. The pumped liquid can be sterile liquids such as water or saline. A specified volume of liquid can be pumped out according to a signal sent by a controller and enter the balloon through the first branch for use in the patient's rehabilitation training.

[0086] According to an embodiment of the present invention, a pressure sensor is connected to a balloon via a second branch of a conduit to detect 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 closed communicating vessel. During rehabilitation training, the liquid pressure inside 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 it can be remotely connected to the patient's mobile device to display the pressure data on the mobile device, allowing the patient to observe in real time whether their exertion during rehabilitation training has brought the liquid pressure data to the target level indicated by the training prompts.

[0087] According to an embodiment of the present invention, a valve is used to switch between a first branch and a second branch. The first branch and the second branch can be switched according to a signal from the controller. When switched to the first branch, the second branch is cut off, preventing the transmission of liquid pressure data to the pressure sensor. When switched to the second branch, the first branch is cut off, preventing the pumping of liquid into the balloon. This also prevents pressure from being transmitted to the liquid pump through the first branch when the patient exerts force.

[0088] According to an embodiment of the present invention, a balloon is inserted into the patient's rectum. During rehabilitation training, the patient's sphincter muscles forcefully squeeze the balloon, increasing the fluid pressure inside the balloon. The fluid pressure data is then measured to determine the extent of sphincter muscle exertion. The better the patient's recovery, the more fluid can be pumped into the balloon, increasing its resistance and thus the difficulty of the rehabilitation training. Conversely, less fluid can be pumped into the balloon to reduce the difficulty. Based on this approach, the difficulty of rehabilitation training can be gradually increased, thereby improving its efficiency.

[0089] According to an embodiment of the present invention, the controller is used to: send a first prompt message to the patient to relax the sphincter muscles. This first prompt message can be sent via a mobile phone screen display, loudspeaker playback, or other means, prompting the patient to prepare for the infusion of fluid into the balloon. For example, the controller can send a "Please relax" first prompt message as a text message to the mobile phone of a patient undergoing rehabilitation training. The patient must relax the sphincter muscles after receiving the first prompt message.

[0090] 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. Since patients undergoing rehabilitation training have weaker sphincter control, the first branch can be opened and the second branch disconnected 5 seconds after the first prompt message is issued, allowing sufficient time for the patient to relax their sphincter. The first volume can be determined based on the patient's rehabilitation status. When the patient's rehabilitation 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 limit this.

[0091] According to an embodiment of the present invention, a control valve disconnects the first branch and opens the second branch. After the control fluid pump pumps a first volume of liquid into the balloon, the first branch can be disconnected to prevent pressure from being transmitted to the fluid pump through the first branch when the patient exerts force, and the second branch can be opened so that the liquid pressure inside the balloon can be transmitted to the pressure sensor through the second branch when the patient exerts force.

[0092] According to an embodiment of the present invention, training prompt messages are sent to the patient. These prompt messages can be sent in the same manner as the first prompt message. For example, the controller can send text messages such as "Please exert force to achieve a fluid pressure of 40 mmHg" and "Please exert force slowly for 5 seconds to achieve 20 mmHg" to the patient's mobile phone during rehabilitation training. Upon receiving the training message, the patient must control their sphincter muscles as required.

[0093] In this way, the controller can send an initial 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. Then, the controller can control the valve to disconnect the first branch and open the second branch, collect liquid pressure data, and thus send a training prompt message to the patient to start training, providing basic data for determining the patient's rehabilitation status.

[0094] According to an embodiment of the present invention, determining the patient's rehabilitation status information based on the training prompt message and the fluid pressure data detected after the training prompt message is issued includes: determining force training target data and control training target data based on the training prompt message; determining a force status coefficient based on the force training target data and the fluid pressure data; determining a control status coefficient based on the control training target data and the fluid pressure data; and determining the patient's rehabilitation status information based on the force status coefficient and the control status coefficient.

[0095] According to an embodiment of the present invention, force training target data and control training target data are determined based on training prompt messages. The training prompt message indicates the target pressure the patient needs to achieve, which is the force training data. For example, if the training prompt message is "Please exert force to reach 40 mmHg," then the force training target data is 40 mmHg. The control training target data may include the target pressure the patient needs to achieve during control training and the time required to achieve the target pressure. For example, if the training prompt message is "Please exert force slowly for 5 seconds to reach 20 mmHg," then the target pressure the patient needs to achieve during control training is 20 mmHg, and the time required to achieve the target pressure is 5 seconds. Since the force 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 less than that in the force training target data.

[0096] According to an embodiment of the present invention, determining a force condition coefficient based on force training target data and liquid pressure data includes: acquiring liquid pressure data at multiple moments within a first preset time period after the moment a training prompt message is issued; 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 within 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.

[0097] According to an embodiment of the present invention, liquid pressure data is acquired at multiple moments within a first preset time period after the moment the training prompt message is issued. After receiving the training prompt message, the patient begins to exert force and tries to reach the force training target data as much as possible. The patient may be asked to exert force and maintain it for a certain duration, 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, and sufficient liquid pressure data may be collected within the first preset time period to determine the patient's force status 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 when the liquid pressure data reaches the maximum value is the first moment. The minimum value of the liquid pressure data at multiple moments within the time period between the first moment and the end of the first preset time period is the first minimum value. The average value of the liquid pressure data at all moments within the time period between the first moment and the end of the first preset time period is the first average value.

[0098] According to an embodiment of the present invention, determining the force condition coefficient based on 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). ,

[0099] (1),

[0100] in, The first maximum value, This is the first average value. The first minimum value, The strength training target data, This is the end time of the first preset time period. For the first moment, The duration of the first preset time period. A coefficient that is less than 1 and greater than 0. For the first time since the first moment, less than The time corresponding to the liquid pressure data.

[0101] According to an embodiment of the present invention, since, under good recovery conditions, the patient's first maximum value within a first preset time period can reach the strength training target data (i.e., the patient's exertion ability can reach the target exertion ability), and can be maintained until the end of the first preset time period, therefore, 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 exertion ability should always reach the target exertion ability in strength training. If the recovery condition is poor, the first maximum value may not reach the strength training target data or may be difficult to maintain 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), This information represents the ratio of the first maximum value to the target data for strength training, which can describe the patient's ability to exert force under optimal conditions during strength training. This information represents the ratio of the first average value to the target data for strength training, which can describe the patient's ability to maintain strength during strength training. The information representing the ratio of the first minimum value to the force training target data describes the patient's ability to exert force at its worst point (i.e., the ability to exert force when unable to maintain a relatively high exertion level) while maintaining a high exertion level. Therefore, It can represent a patient's overall force exertion ability during strength training, serve as a proportion of information for assessing a patient's force exertion ability, and describe the force exertion ability demonstrated by a patient during strength training.

[0102] According to an embodiment of the present invention, in formula (1), since the patient's force reaches the first maximum value, during the process of maintaining a large force exertion, it may not be possible to maintain the maximum force state indefinitely, and the liquid pressure data will gradually decrease instead of instantly decreasing to 0. Therefore, This can be represented as the target pressure (i.e., the minimum fluid pressure required to maintain force exertion under normal circumstances) during strength training after the patient has reached the first maximum force exertion. It can be considered the target maintenance pressure. For example, manually set empirical values. .when When the patient reaches the first maximum force, it indicates that during 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 exerted. Therefore, in formula (1), This represents the duration between the end of the first preset time period and the first moment. It can be considered the duration for which force is maintained while applying it. Therefore... The proportion of the duration of force exertion to the first preset time period can represent the ability to reach the maximum force and maintain force exertion.

[0103] According to an embodiment of the present invention, in formula (1), when When the first minimum value is less than the target maintenance pressure, after the patient reaches the first maximum value, the force gradually decreases during the maintenance process, and at a certain point, the target maintenance pressure cannot be reached. It can be considered that the force has not been maintained. Therefore, in formula (1), This indicates the first time a value less than [a certain value] was collected after the first moment. The duration between the time corresponding to the liquid pressure data and the first time point is such that, because the patient cannot maintain exertion during the period from the moment they cannot maintain exertion until the end of the first preset time period, therefore... This refers to the duration for which the patient can maintain exertion. The ratio of the duration of sustained exertion to the first preset time period describes the patient's ability to maintain exertion during strength training. Therefore, The product of the proportion of information assessing a patient's ability to maintain force exertion and the proportion of information assessing a patient's ability to exert force can be used as a strength condition coefficient, which can comprehensively describe the patient's sphincter muscle's ability to exert force and maintain it from both the aspects of force exertion and maintenance. The larger the strength condition coefficient, the stronger the patient's sphincter muscle's ability to exert force and maintain it during this strength training; conversely, the smaller the strength condition coefficient, the weaker the patient's sphincter muscle's ability to exert force and maintain it during this strength training.

[0104] In this way, by testing both the patient's ability to exert force and their ability to maintain it, the strength training status coefficient can be determined, accurately and comprehensively describing the recovery status of the sphincter's ability to exert force, thus improving the accuracy and objectivity of the strength training status coefficient.

[0105] According to an embodiment of the present invention, the training prompt message includes a frequency control training prompt message and a hold control training prompt message; determining the control status coefficient based on control training target data and liquid pressure data includes: determining a second moment when the frequency control training prompt message is issued each time, and a third moment when liquid pressure data is detected to be higher than a detection threshold during the time interval between two adjacent second moments; detecting liquid pressure data at multiple moments during the action time interval after the hold control training prompt message is issued; and determining the control status coefficient based on the second moment, the third moment, the liquid pressure data during the action time interval, and the control training target data.

[0106] According to an embodiment of the present invention, the frequency control training prompt message can be multiple training prompt messages to prompt the patient to perform frequency control training. For example, sending a "Please exert force" training prompt message to the patient every 2 seconds is the frequency control message. The hold control training prompt message can prompt the patient to perform hold control training. For example, sending the message "Please exert force slowly for 5 seconds to reach 20 mmHg" to the patient. The moment when each frequency control training prompt message is sent is the second moment. The detection threshold is the minimum fluid pressure data for effective sphincter muscle exertion under normal conditions. When the fluid pressure data is less than the detection threshold, the patient's force is too small and cannot effectively control the sphincter muscle exertion, and the patient can be considered to have failed in this training session. Conversely, when the fluid pressure data is greater than or equal to the detection threshold, the patient's force exertion is effective, and the patient can be considered to have successfully exerted force and completed one frequency control training session. The moment when the fluid pressure data is detected to be higher than the detection threshold in the time interval between two adjacent second moments is the third moment (i.e., the moment when the patient successfully exerts force). Furthermore, during the action period following the issuance of the maintain control training prompt message, liquid pressure data at multiple moments are detected. When detecting liquid pressure data at multiple moments within this time period, the time interval between adjacent moments can be 0.1 seconds.

[0107] According to an embodiment of the present invention, determining the control status coefficient based on the liquid pressure data and control training target data during the second time moment, the third time moment, and the action time period includes: determining the preset reaction time based on the control training target data; determining the control training intensity data and the duration of the action time period based on the control training target data; and determining the control status coefficient according to formula (2). ,

[0109] in, To preset the reaction time, For the second moment after the i-th frequency control training prompt message is issued, The third time interval is the time between the second moment of the i-th frequency control training prompt message and the second moment of the (i+1)-th frequency control training prompt message. This refers to the second moment when the frequency control training prompt message is issued for the (i+1)th time. This refers to the time before the second moment when the (i+1)th frequency control training prompt message is issued. The liquid pressure data detected at time t. The threshold is set to `max`, which is the function to maximize the value. `n` is the frequency control, which determines the number of training prompts, where `i ≤ n`. For the k-th moment within the action time period corresponding to the s-th maintain control training cue message, The (k+1)th time interval within the action time period corresponding to the s-th maintenance control training cue message. For the control training intensity data corresponding to the s-th control training cue message, For the control training intensity data corresponding to the (s-1)th hold control training cue message, when s=1, , Let be the duration of the action time period corresponding to the s-th control training cue message. for Real-time detected liquid pressure data, for Real-time detected liquid pressure data, Let N be the number of moments within the action time period corresponding to the s-th hold-control training cue message, and let N be the number of hold-control training cue messages, where k ≤ , s≤N, and i, n, k, , s, and N are all positive integers.

[0110] According to an embodiment of the present invention, a preset reaction time is determined based on control training target data. The target time between the moment the patient receives the frequency control training prompt message and the moment when the required force is exerted to reach the detection threshold of the liquid pressure data (i.e., the reaction time required for successful force exertion under normal circumstances) is the preset reaction time, for example, 0.5 seconds. Control training intensity data and the duration of the action time period are determined based on the control training target data. The target pressure that the patient needs to achieve, as prompted by the control training target data, is the control training intensity data, and the target duration for the patient to exert force is the duration of the action time period. For example, if the control training target data is "Please exert force slowly for 5 seconds to reach 20 mmHg," then the control training intensity data is 20 mmHg, and the duration of the action time period is 5 seconds.

[0111] According to an embodiment of the present invention, in formula (2), This represents the variable representing the control training intensity data corresponding to the s-th and s-1-th control training cue messages (when s=1, ),therefore, The variable representing the control training force data, and its ratio to the duration of the action time period corresponding to the s-th hold control training cue message, can be considered as the target rate of change of the control training force data corresponding to the s-th hold control training cue message. Since, under normal circumstances, the rate of change is the same at each moment within the action time period corresponding to the s-th hold control training cue message (i.e., uniform force application), therefore... It can be used as the target change rate within the time interval between each moment of the action time interval corresponding to the s-th maintain control training prompt message. It can represent the actual rate of change of liquid pressure data between the kth and k+1th times within the action time period corresponding to the sth control training prompt message.

[0112] According to an embodiment of the present invention, when At that time, the target rate of change is in the same direction as the actual rate of change, and the patient's force direction is correct. However, the rate of change of force may differ from the target rate of change. This can represent the relative difference between the target change rate and the actual change rate between the k-th and k+1-th times within the action time period corresponding to the s-th control training cue message, where 1 is the difference between the aforementioned relative difference. It can be used to assess the patient's ability to maintain control at a given moment, and can describe the patient's ability to maintain control.

[0113] According to an embodiment of the present invention, when If the actual rate of change is 0 or the target rate of change is opposite in direction to the actual rate of change, the patient's force application direction does not meet the requirements of this control maintenance training. The corresponding assessment value for the patient's control maintenance ability at that moment is 0. For example, if the control maintenance training prompt is "Please slowly exert force for 5 seconds to reach 20 mmHg," and the patient does not exert force or the force gradually decreases, the force application does not meet the requirements of the control maintenance training, and the corresponding assessment value for the patient's control maintenance ability is 0. Therefore, This can represent the average value of the ability to maintain control at various times within the action time period corresponding to the s-th control maintenance training cue message, and can represent the patient's ability to maintain control during training for that control maintenance training cue message. It describes the patient's ability to maintain control during training in response to multiple control training prompts. The higher the value, the stronger the patient's ability to maintain control during control training.

[0114] According to an embodiment of the present invention, in formula (2), This represents the maximum value of the liquid pressure data detected at multiple moments between the second moment of the i-th and i+1-th frequency control training prompt messages. The patient's exertion force gradually increases. The maximum value of the patient's exertion force between the second moment of the i-th and i+1-th frequency control training prompt messages is the patient's maximum exertion force during the i-th frequency control training process. This maximum exertion force can be used to determine whether the patient's exertion ability meets the standard, that is, to determine whether the patient successfully exerted force during the i-th frequency control training process. If the exertion force is successful, subsequent calculations on the reaction time are performed to determine the patient's reaction speed and frequency control ability. If the exertion force is unsuccessful, it indicates that the patient cannot effectively control the sphincter muscle. In the case of ineffective sphincter muscle exertion, the patient can be considered unable to respond to the training prompt messages, therefore 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 and completes the i-th frequency control training session; otherwise, when... When the maximum value is less than the detection threshold, the patient exerts too little force in the i-th frequency control training and cannot effectively control the sphincter muscle force, which can be considered as the patient's failure to exert force.

[0115] According to an embodiment of the present invention, in formula (2), when At that moment, the patient successfully exerted force; in this situation, The third moment, representing the time between the (i+1)th and second moments of the frequency control training prompt message, and the second moment of the ith frequency control training prompt message, can be considered the actual reaction time for the patient to successfully exert force during the ith frequency control training (i.e., the actual time from receiving the frequency control training prompt message to successfully exerting force, which can also represent the patient's reaction speed). Therefore... The information representing the ratio of the preset reaction time to the actual reaction time can be considered as the ratio information for assessing the patient's frequency control ability and can describe the patient's frequency control ability.

[0116] According to an embodiment of the present invention, when When the patient fails to exert force, their frequency control ability is 0 for the i-th frequency control training prompt message, indicating that the patient has not completed this frequency control training. Therefore, This represents the average value of the frequency control ability assessment corresponding to each frequency control training prompt message issued. It describes the frequency control ability demonstrated by the patient in this frequency control training. The larger the average value, the stronger the frequency control ability demonstrated by the patient in this control training.

[0117] According to an embodiment of the present invention, the product of the above two items can be used as the patient's control status coefficient. The control status coefficient can comprehensively describe a patient's sphincter control ability from two aspects: maintenance control and frequency control. The larger the control status coefficient, the stronger the patient's sphincter control ability in this control training; conversely, the smaller the control status coefficient, the weaker the patient's sphincter control ability in this control training.

[0118] According to an embodiment of the present invention, the patient's rehabilitation status information is determined based on the strength condition coefficient and the control condition coefficient. The rehabilitation status information may include the strength condition coefficient and the control condition coefficient corresponding to the patient's current rehabilitation training. For example, if the strength 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 "strength condition coefficient is 0.5, control condition coefficient is 0.7".

[0119] In this way, based on the training target data for strength and control, as well as the fluid pressure data, the strength status coefficient and control status coefficient can be determined. This allows for the assessment of the patient's rehabilitation status information during the rehabilitation training, providing insights into both strength and control. By considering that the strength status coefficient encompasses both exertion and maintenance abilities, and that the control status coefficient includes both frequency control and maintenance control abilities, the accuracy, comprehensiveness, and objectivity of the strength status coefficient, control status coefficient, and patient rehabilitation status information are improved.

[0120] According to an embodiment of the present invention, the training prompt message for the next rehabilitation training is determined based on the patient's rehabilitation status information, including: when the strength status coefficient is higher than or equal to a first strength coefficient threshold, or lower than a second strength coefficient threshold, determining the strength training target data adjustment coefficient according to formula (3). ,

[0121] (3),

[0122] in, For the force condition coefficient, A coefficient that is less than 1 and greater than 0. The first force coefficient threshold, A coefficient greater than 1 The second strength coefficient threshold, The strength training target data is adjusted according to the strength training target data adjustment coefficient to obtain the adjusted strength training target data; when the control status coefficient is higher than or equal to the first control coefficient threshold, or lower than the second control coefficient threshold, the first control training target data adjustment coefficient is determined according to formula (4). ,

[0123] (4),

[0124] in, To control the condition coefficient, The first control coefficient threshold, The second control coefficient threshold, , and The coefficients are less than 1 and greater than 0; the adjustment coefficients for the second control training target data are determined according to formula (5). ,

[0125] (5),

[0126] The second control training target data adjustment coefficient is used to adjust the variance of the control training target data; the control training target data is adjusted according to the first and second control training target data adjustment coefficients to obtain the adjusted control training target data; and the training prompt message for the next rehabilitation training is obtained based on the adjusted control training target data and the adjusted intensity training target data.

[0127] 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 (e.g., 0.8), the patient demonstrates good sphincter muscle strength during this rehabilitation training. The current strength training difficulty is too simple for the patient and cannot achieve the desired training effect. Since a larger strength training data point indicates a greater difficulty level, the target strength training data can be increased to enhance the training difficulty. Conversely, when... When the strength condition coefficient is lower than the second strength coefficient threshold (e.g., 0.3), the patient's sphincter strength ability is very poor in this rehabilitation training. The current strength training is too difficult for the patient to complete. Therefore, the strength training target data can be reduced to reduce the difficulty of strength training.

[0128] According to an embodiment of the present invention, in formula (3), when hour, This represents the difference between the strength condition coefficient and the first strength coefficient threshold. It describes the gap between the patient's current strength training result and the training goal. 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. The coefficient is less than 1 and greater than 0; therefore, it can be obtained through... The scaling factor for the strength training target data is adjusted by reducing its size to obtain an adjusted scaling factor. Based on the above processing method, the scaling factor for the strength training target data can be kept within a reasonable range, reducing the possibility that the patient will be unable to reach the adjusted strength training target data due to an excessively large scaling factor. This allows the difficulty of the strength training to be increased while still enabling the patient to complete the training, thus yielding the adjusted scaling factor for the strength training target data. Similarly, when At that time, it can be done through The reduction factor for the strength training target data By increasing the adjustment, a reduction coefficient is obtained for the adjusted strength training target data, which reduces the difficulty of strength training, making it easier for patients to complete the training. This allows us to obtain the adjustment coefficient for the strength training target data. .

[0129] According to an embodiment of the present invention, the strength training target data is adjusted according to the strength training target data adjustment coefficient to obtain the adjusted strength training target data. This adjusts the difficulty of the strength training, improving the effectiveness of rehabilitation training while ensuring the patient can complete the training. For example, if the strength training target data for this rehabilitation training is 20 mmHg, and the strength training target data adjustment coefficient is 1.1, the adjusted strength training target data is the product of 20 and 1.1, which is 22 mmHg.

[0130] According to an embodiment of the present invention, in formula (4), when When the control status coefficient is higher than or equal to the first control coefficient threshold (e.g., 0.8), the patient demonstrates good sphincter control during this control training. The current control training in rehabilitation is too simple for the patient and cannot achieve the desired training effect. Since a shorter preset reaction time results in greater difficulty of control training, the preset reaction time can be shortened to increase the difficulty of control training. Conversely, when... If the control status coefficient is lower than the second control coefficient threshold (e.g., 0.3), the patient's sphincter control ability is very poor in this rehabilitation training. The control training in the current rehabilitation training is too difficult for the patient to complete. 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.

[0131] According to an embodiment of the present invention, similar to formula (3), It can be used as a shortening factor for the preset reaction time, because and The coefficient is less than 1 and greater than 0; therefore, it can be obtained through... The shortening factor of the preset reaction time is reduced and adjusted to obtain the adjusted shortening factor. 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 will be unable to achieve the adjusted preset reaction time and movement time due to an excessively large shortening coefficient. This improves the effectiveness of rehabilitation training while ensuring the patient can complete the training, thereby obtaining the adjustment coefficient for the first control training target data. Similarly, it can be achieved through... Extension coefficient of preset reaction time Adjustments are made to reduce the possibility that an excessively large extension coefficient will result in an overly long preset reaction time, making the training difficulty too simple for the patient and thus failing to achieve the desired training effect. This allows for the determination of 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.

[0132] 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 (the variance of the control training intensity data and the duration of the action time period in multiple control training prompt messages) in the maintenance control training. The higher the variance, the greater the difference between the control training intensity data and the duration of the action time period, and the more difficult it is to maintain control. Since the larger the variance in the control training target data, the greater the fluctuation of the control training target data, the more difficult it is to control, and the greater the difficulty of control training, similar to formula (4), when At times, the control training in current rehabilitation programs is too simple for the patient, failing to achieve the desired training effect. In such cases, increasing the variance of the control training target data can increase the difficulty of the control training and improve the effectiveness of the rehabilitation training. Conversely, when… At present, the control training in rehabilitation training is too difficult for patients to complete. To reduce the variance of the control training target data, the difficulty of control training can be reduced, ensuring that patients complete rehabilitation training.

[0133] According to an embodiment of the present invention, similar to formula (3), when hour, This can represent the adjustment coefficient of the second control training target data, which can be achieved through... The amplification factor for the variance of the control training target data is reduced to decrease the likelihood that the patient will maintain control training after completing the adjusted training due to an excessively large amplification factor. This improves the effectiveness of rehabilitation training when the patient can complete the training, and conversely, when... hour, This can represent the adjustment coefficient of the second control training target data, which can be achieved through... The reduction factor of the variance of the control training target data is adjusted to reduce the possibility that the variance of the control training target data is too small due to an excessively large reduction factor, making the control training too simple for the patients and failing to achieve the training effect.

[0134] According to an embodiment of the present invention, the control training target data is adjusted according to 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 intensity data and the duration of the action time period) is the variance of the adjusted control training target data. The adjusted control training target data is obtained by adjusting the control training target data according to the adjusted preset reaction time and the adjusted variance of the control training target data.

[0135] According to an embodiment of the present invention, a training prompt message for the next rehabilitation training session is obtained based on the adjusted control training target data and the adjusted intensity training target data. Similar to generating the training prompt message for the current rehabilitation training session, the adjusted preset reaction time, the variance of the adjusted control training target data, and the adjusted intensity training data can be determined based on the adjusted control training target data and the adjusted intensity training target data. This generates a plan and training prompt message for the next rehabilitation training session, making the difficulty of the next rehabilitation training more suitable for the patient and improving the effectiveness of the next rehabilitation training.

[0136] In this way, based on the patient's rehabilitation status information, adjustment coefficients for the intensity training target data, the first control training target data, and the second control training target data can be obtained, thus yielding adjusted control training target data and adjusted intensity training target data. This allows for the generation of training prompt messages for the next rehabilitation training session. Furthermore, considering situations where the adjustment coefficients are too large or too small, the above adjustment coefficients are adjusted accordingly, improving the matching degree between the adjusted training difficulty and the patient's recovery status, enhancing the accuracy of patient rehabilitation status assessment, and improving the efficiency of patient rehabilitation training.

[0137] According to an embodiment of the present invention, a pelvic floor muscle rehabilitation system based on an artificial dilatation balloon after rectal cancer sphincter preservation surgery can issue a first prompt message to the patient to relax the sphincter muscles. After controlling the valve to open the first branch and disconnect the second branch, and controlling the liquid pump to pump a first volume of liquid into the balloon, the system controls the valve to disconnect the first branch and open the second branch, issues a training prompt message to the patient, and detects liquid pressure data to determine the patient's rehabilitation status information, thereby determining the training prompt message for the next rehabilitation training. The system can determine the patient's rehabilitation status based on the patient's strength and control status, and formulate a training plan for the next rehabilitation training based on the rehabilitation status, reducing reliance on doctors, improving the accuracy of patient rehabilitation status assessment, and increasing the efficiency of patient rehabilitation training. The system can issue a first prompt message to the patient via a controller, control the valve to open the first branch and disconnect the second branch, control the liquid pump to pump a first volume of liquid into the balloon, then control the valve to disconnect the first branch and open the second branch, collect liquid pressure data, and thus issue a training prompt message to the patient to start training, providing basic data for determining the patient's rehabilitation status information. When determining the strength condition coefficient, the patient's ability to exert force and maintain it can be assessed to determine the strength training condition coefficient, accurately and comprehensively describing the recovery status of the sphincter's exertion ability and improving the accuracy and objectivity of the strength training condition coefficient. Furthermore, based on strength training target data, control training target data, and fluid pressure data, strength condition coefficients and control condition coefficients can be determined, thereby identifying the patient's rehabilitation status information from both strength and control perspectives. By considering that the strength condition coefficient includes both exertion and maintenance abilities, and that the control condition coefficient includes both frequency control and maintenance control abilities, the accuracy, comprehensiveness, and objectivity of determining the strength condition coefficient, control condition coefficient, and patient rehabilitation status information are improved. Furthermore, based on the patient's rehabilitation status information, adjustment coefficients for the intensity training target data, the first control training target data, and the second control training target data can be obtained, thus yielding adjusted control training target data and adjusted intensity training target data. This allows for the generation of training prompt messages for the next rehabilitation training session. Furthermore, considering cases where the adjustment coefficients are too large or too small, the aforementioned adjustment coefficients are adjusted, improving the match between the adjusted training difficulty and the patient's recovery status, enhancing the accuracy of patient rehabilitation status assessment, and increasing the efficiency of patient rehabilitation training.
