Description

Technical Field

[0001] This invention relates to the field of postoperative rehabilitation and nursing equipment technology, specifically to an intelligent monitoring and auxiliary intervention device for the recovery of gastrointestinal function after endometriosis surgery. Background Technology

[0002] In gynecological clinical practice, patients with endometriosis who undergo laparoscopic surgery often experience complications due to extensive pelvic adhesions, large surgical wounds, and ongoing complications during the procedure. Multiple factors, such as pneumoperitoneum inhibiting intestinal peristalsis, lead to delayed recovery of gastrointestinal function after surgery.

[0003] Currently, clinical assessment of postoperative gastrointestinal function recovery primarily relies on nurses periodically auscultating the abdomen with a stethoscope, subjectively judging the frequency and intensity of bowel sounds to indirectly assess intestinal motility. This method suffers from discontinuous monitoring, strong subjectivity in assessment, and the inability to quantify and record data, making it difficult to capture dynamic changes in intestinal motility in real time and potentially missing the optimal intervention window. Regarding interventions to promote gastrointestinal function recovery, conventional methods such as encouraging early ambulation and abdominal massage rely heavily on the experience of medical staff and the patient's self-awareness in terms of frequency, intensity, and effectiveness. They lack objective, quantifiable implementation standards and timely feedback and adjustment mechanisms, hindering individualized and precise postoperative rehabilitation management. Furthermore, existing postoperative monitoring or rehabilitation equipment often has limited functionality, primarily passively monitoring routine physiological parameters such as ECG and blood oxygenation, or only providing pre-programmed physical stimulation. It generally lacks the ability to perform real-time intelligent assessment based on bowel sounds—a core gastrointestinal function signal—and cannot dynamically generate and implement personalized intervention plans based on assessment results, failing to establish a complete process of monitoring, assessment, intervention, and optimization.

[0004] Therefore, existing technologies suffer from problems such as discontinuous postoperative gastrointestinal function monitoring, subjective assessment, untimely intervention, and a lack of quantitative and personalized guidance. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent monitoring and auxiliary intervention device for the recovery of gastrointestinal function after endometriosis surgery, so as to overcome the above-mentioned problems of the prior art and realize continuous monitoring, intelligent assessment and automatic precise intervention for the recovery of gastrointestinal function after surgery.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A smart monitoring and auxiliary intervention device for gastrointestinal function recovery after endometriosis surgery includes an abdominal bandage, a control unit fixed to the outer layer of the abdominal bandage, and a bowel sound acquisition sensor array and a feedback massage unit fixed to the inner layer of the abdominal bandage, wherein: The control unit includes a power supply module, a processing and evaluation module, and a Bluetooth communication module, and is electrically connected to the bowel sound acquisition sensor array and the feedback massage unit. The processing and evaluation module receives the bowel sound signals, performs time-frequency transformation and denoising processing to obtain a denoised frequency sequence, extracts signal feature parameters from the denoised frequency sequence, identifies and marks weak signal segments, classifies persistently abnormal weak signal segments, and, based on the classification results, finally outputs an evaluation result reflecting the state of intestinal peristalsis. The processing and evaluation module is also used to generate intervention control commands based on the evaluation results. The Bluetooth communication module is used to send the evaluation results to an external nursing terminal. The bowel sound acquisition sensor array is used to be attached to the patient's abdomen to collect abdominal bowel sound signals in real time. The feedback massage unit is used to perform tactile stimulation according to the intervention control command.

[0007] Furthermore, the device also includes a drainage tube fixing buckle, which is disposed on the abdominal strap to fix the abdominal drainage tube.

[0008] Furthermore, the device also includes an activity monitoring sensor electrically connected to the control unit for monitoring the patient's activity data and transmitting the activity data to the external nursing terminal via the Bluetooth communication module.

[0009] Furthermore, the bowel sound acquisition sensor array consists of multiple independent bowel sound sensors arranged in a ring array.

[0010] Furthermore, the feedback massage unit includes multiple vibration motors arranged in a ring within the inner layer of the abdominal strap.

[0011] Furthermore, the time-frequency transformation and denoising process includes: Perform a Fourier transform on the bowel sound signal to obtain a frequency domain feature sequence; The frequency domain feature sequence is subjected to wavelet transform to remove noise components, and the denoised signal is reconstructed in the time domain to obtain the denoised frequency sequence.

[0012] Furthermore, the signal characteristic parameters include peak amplitude and frequency distribution parameters.

[0013] Furthermore, the classification of weak segments of persistently abnormal signals is performed using a support vector machine algorithm.

[0014] Another objective of this invention is to provide a method for intelligent monitoring and auxiliary intervention of gastrointestinal function recovery after endometriosis surgery, using the aforementioned intelligent monitoring and auxiliary intervention device for gastrointestinal function recovery after endometriosis surgery, the method comprising: Abdominal bowel sound signals are collected in real time using a bowel sound acquisition sensor array; The bowel sound signal is processed by the processing and evaluation module, including: performing time-frequency transformation and denoising to obtain a denoised frequency sequence, extracting signal feature parameters from the denoised frequency sequence to identify and label weak signal segments, and classifying persistently abnormal weak signal segments to output an evaluation result reflecting the state of intestinal peristalsis. Based on the assessment results, intervention control instructions are generated; According to the intervention control command, the feedback massage unit is driven to provide tactile stimulation to the patient's abdomen; The assessment results are sent to an external care terminal via a Bluetooth communication module.

[0015] Furthermore, the step of generating intervention control instructions based on the assessment results specifically includes: Based on the assessment results, the matching degree is calculated by combining pre-stored rehabilitation history data that reflects the individual characteristics of the patients; The working parameters of the feedback massage unit are dynamically adjusted based on the matching results to form a personalized intervention protocol sequence for controlling the working mode and timing of the feedback massage unit. During the execution of the intervention protocol sequence by the feedback massage unit, the parameters of the intervention protocol sequence are iteratively optimized based on the real-time feedback of bowel sounds.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention replaces the traditional intermittent and subjective manual auscultation with a ring-shaped array of bowel sound acquisition sensors, enabling continuous and objective acquisition of abdominal bowel sound signals, providing a stable and reliable data source for assessment, and realizing dynamic and objective continuous monitoring; 2. The processing and evaluation module performs professional digital signal processing and feature analysis on the collected signals, and uses classification algorithms to automatically identify and classify the state of bowel sounds, transforming the state of intestinal peristalsis into objective and quantifiable evaluation results, which significantly improves the accuracy and consistency of the evaluation. 3. A precise, closed-loop intervention system has been constructed. Based on intelligent assessment results, the device can automatically determine and trigger the feedback massage unit to provide physical stimulation intervention, forming a closed loop of monitoring, assessment, and intervention. Furthermore, by combining individual patient historical data to generate personalized intervention protocols and iteratively optimizing them based on real-time feedback, the intervention measures become more precise and adaptive, effectively promoting the recovery of intestinal peristalsis. 4. Improved postoperative care efficiency and safety. The integrated drainage tube fixation clip and activity monitoring function facilitate early postoperative mobilization, aligning with the Enhanced Recovery After Surgery (ERAS) concept. Simultaneously, all data is uploaded to the nursing terminal via Bluetooth, enabling remote and centralized monitoring, reducing the workload of medical staff, helping to lower the risk of postoperative complications such as intestinal adhesions and intestinal obstruction, and accelerating the patient's recovery process.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0019] This embodiment provides an intelligent monitoring and auxiliary intervention device for the recovery of gastrointestinal function after endometriosis surgery. (See also...) Figure 1 The device includes an abdominal bandage 1, a control unit 2 fixed to the outer layer of the abdominal bandage, and a bowel sound acquisition sensor array 3 and a feedback massage unit 4 fixed to the inner layer of the abdominal bandage. The abdominal bandage 1 can be worn on the patient's abdomen and is made of elastic, breathable medical material. It can be adapted to patients with different abdominal circumferences via Velcro or buckles.

[0020] The control unit 2 is an integrated rigid housing containing a power supply module, a processing and evaluation module, and a Bluetooth communication module, and is electrically connected to the bowel sound acquisition sensor array 3 and the feedback massage unit 4. In this embodiment, the power supply module uses a rechargeable lithium battery and is equipped with a charging interface. The processing and evaluation module is based on a microprocessor and runs an embedded program. The processing and evaluation module is used to receive the bowel sound signal, perform time-frequency transformation and noise reduction processing to obtain a denoised frequency sequence, extract signal feature parameters from the denoised frequency sequence, identify and mark weak signal segments, classify persistently abnormal weak signal segments, and based on the classification results, finally output an evaluation result reflecting the state of intestinal peristalsis. The processing and evaluation module is also used to generate intervention control commands based on the evaluation results. The Bluetooth communication module is used to send the evaluation results to an external nursing terminal.

[0021] An array of bowel sound sensors 3 and a feedback massage unit 4 are fixedly installed in the inner layer of the abdominal bandage 1. The bowel sound sensor array 3 is used to attach to the patient's abdomen to collect abdominal bowel sound signals in real time; the feedback massage unit 4 is used to perform tactile stimulation according to the intervention control command. Both the bowel sound sensor array 3 and the feedback massage unit 4 are electrically connected to corresponding modules in the control unit 2 via flexible wires and are powered by a power supply module.

[0022] In one specific embodiment, the bowel sound acquisition sensor array 3 consists of multiple independent, miniaturized bowel sound sensors, such as piezoelectric ceramic sensors, arranged in a ring array. This ring arrangement allows it to cover multiple key auscultation areas of the abdomen, thereby acquiring bowel sound signals more comprehensively. The feedback massage unit 4 includes multiple miniature vibration motors arranged in a ring within the inner layer of the abdominal bandage 1. When triggered, these vibration motors can generate tactile vibration stimulation of different intensities, patterns, and durations.

[0023] In a preferred embodiment, the device further includes a drainage tube fixing buckle 5. The drainage tube fixing buckle 5 is located on the outer side or edge of the abdominal bandage 1. At a predetermined position corresponding to the abdominal wall outlet of the patient's abdominal drainage tube, the abdominal bandage 1 may have a clearance hole, such as... Figure 1 The rectangular hole shown is for the drainage tube to pass through. The drainage tube fixing buckle 5 is used to securely fix the external section of the drainage tube to the surface of the bandage after it has passed through. This design solves the problems of easy allergies and easy fall-off of traditional adhesive tape fixation. It can effectively prevent the drainage tube from being accidentally pulled and displaced when the patient moves, and avoids direct pressure on the drainage tube and puncture site by the main body of the bandage, while also facilitating observation by nurses.

[0024] In addition, the control unit 2 integrates activity monitoring sensors, such as a three-axis accelerometer and a gyroscope. These sensors continuously monitor the patient's physical movement, identifying and recording data such as the number of steps, duration, and intensity of activities taken after getting out of bed using a specific algorithm. This activity data, along with bowel sound assessment results, is synchronously transmitted to an external nursing terminal via the Bluetooth communication module, providing objective evidence for medical staff to comprehensively assess the patient's postoperative recovery motivation and overall rehabilitation progress.

[0025] The specific working process of this device is as follows: First, the bowel sound acquisition sensor array 3 continuously acquires raw bowel sound signals from the patient's abdomen and transmits them to the processing and evaluation module of the control unit 2. Simultaneously, the activity monitoring sensor within the control unit continuously monitors the patient's movement data.

[0026] The processing and evaluation module processes the raw bowel sound signal, first through time-frequency transformation and denoising. Specifically, the Fourier Transform (FFT) algorithm is used to transform the time-domain signal to the frequency domain, obtaining a frequency-domain feature sequence. The wavelet transform algorithm is then used to perform multi-scale decomposition on this frequency-domain feature sequence. Wavelet coefficients related to interference noise such as heart sounds and breath sounds are thresholded or attenuated to remove noise components. Finally, the processed signal is reconstructed in the time domain, resulting in a denoised audio sequence with a significantly improved signal-to-noise ratio.

[0027] The processing and evaluation module then performs feature extraction and preliminary identification. Key feature parameters, such as peak amplitude and frequency distribution parameters, are extracted from the denoised frequency sequence. By comparing the extracted peak amplitude with a pre-set intensity threshold based on clinical data, periods with signal intensity below the threshold are identified and marked as weak signal segments. The system records the start and end times of each marked segment and calculates its duration.

[0028] Next, the processing and evaluation module performs state classification and assessment. The system sets a duration threshold and performs in-depth analysis on weak signal segments with a duration exceeding this threshold. Multidimensional features of these segments are extracted and input into a pre-trained classification model; in this embodiment, a Support Vector Machine (SVM) algorithm is used. This SVM classification model is trained based on a large amount of historical postoperative patient bowel sound data segments and their corresponding clinical assessment labels, such as normal peristalsis or inhibition. Its input consists of multidimensional feature parameters extracted from the weak signal segments with a persistent abnormality, such as peak amplitude, mean and variance of the frequency distribution, and segment duration. The output is the classification result of the current intestinal peristalsis state. The classification model outputs the state categories corresponding to the segments, including normal peristalsis, mild inhibition, and significant inhibition. The processing and evaluation module integrates the classification results over a period of time and finally outputs a quantitative assessment result reflecting the current overall intestinal peristalsis state.

[0029] The subsequent assessment module makes decisions and provides personalized interventions. When the assessment results indicate poor intestinal motility, the module automatically generates intervention control instructions. This process can be further optimized: the assessment module calls pre-stored rehabilitation history data reflecting the patient's individual characteristics and calculates the matching degree between the current state characteristics and historical data patterns, such as calculating cosine similarity. Based on the matching results, the operating parameters of the feedback massage unit 4, such as vibration intensity, mode, and working cycle, are dynamically adjusted to form a personalized intervention protocol sequence, which is specifically a set of control instructions defining intensity, cycle, and duration. The assessment module sends this intervention control instruction to the feedback massage unit 4. Upon receiving the instruction, the feedback massage unit 4 immediately drives its internal micro-vibration motor to work according to the set parameters, providing circular, intermittent vibration stimulation to the patient's abdomen.

[0030] During the intervention, the system enters a closed-loop optimization phase. The bowel sound acquisition sensor array 3 continues to operate, and the monitoring submodule within the processing and evaluation module tracks the changing trend of bowel sound signals after the intervention. If the changing trend does not meet the preset optimization target, for example, if the proportion of weak signal segments does not decrease by more than 10% within 30 minutes after the start of the intervention, the system will automatically iteratively adjust the parameters of the intervention protocol sequence, such as increasing the stimulation intensity, to achieve closed-loop optimization, thereby making the intervention more precise and effective.

[0031] All key data generated during the above process, including bowel sound characteristics, intelligent assessment results, intervention logs based on tactile feedback, and activity data obtained from continuous monitoring, are wirelessly transmitted via the Bluetooth communication module within control unit 2 to external nursing terminals, such as the central monitoring system at the nurse station or mobile nursing devices acting as data relays. This enables medical staff to remotely and in real-time monitor the gastrointestinal function recovery progress and device operating status of multiple patients.

[0032] This embodiment also provides a method for intelligent monitoring and auxiliary intervention of gastrointestinal function recovery after endometriosis surgery, such as... Figure 2 As shown, the method of using the intelligent monitoring and auxiliary intervention device for gastrointestinal function recovery after endometriosis surgery includes: Abdominal bowel sound signals are collected in real time using bowel sound acquisition sensor array 3; The bowel sound signal is processed by the processing and evaluation module, including: performing time-frequency transformation and denoising to obtain a denoised frequency sequence, extracting signal feature parameters from the denoised frequency sequence to identify and label weak signal segments, and classifying persistently abnormal weak signal segments to output an evaluation result reflecting the state of intestinal peristalsis. Based on the assessment results, intervention control instructions are generated; According to the intervention control command, the feedback massage unit 4 is driven to provide tactile stimulation to the patient's abdomen; The assessment results are sent to an external care terminal via a Bluetooth communication module.

[0033] The step of generating intervention control instructions based on the assessment results specifically includes: calculating the matching degree based on the assessment results and combining it with pre-stored rehabilitation history data reflecting individual patient characteristics; dynamically adjusting the working parameters of the feedback massage unit according to the matching results to form a personalized intervention protocol sequence for controlling the working mode and timing of the feedback massage unit; and iteratively optimizing the parameters of the intervention protocol sequence based on real-time feedback of bowel sounds during the execution of the intervention protocol sequence by the feedback massage unit 4.
