[0035] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0036] like Figure 1 and Figure 2 As shown, an intelligent peritoneal dialysis tube wound monitoring dressing includes a dressing body 1, on which a monitoring module 3 for monitoring the skin temperature at the wound is provided; The monitoring module 3 includes a temperature sensing array module 33 for sensing temperature, and the temperature sensing array module 33 is attached to the dressing body 1 via the heat conducting portion 2; An adhesive layer 13 is connected to the surface or outer edge of the dressing body 1 , and the adhesive layer 13 is bonded around the wound.

[0037] The adhesive layer 13 is made of medical-grade hypoallergenic adhesive.

[0038] It can monitor changes in wound skin temperature, generate thermal maps, and use algorithms combined with neural network visual models to intelligently evaluate wound healing, helping to detect potential problems in advance.

[0039] Example 1 like Figure 4 As shown, the monitoring module 3 includes a flexible substrate 31 integrated in the inner cavity of a flexible packaging shell 34, and a thin film battery 32, a Bluetooth communication module and a control cache chip are integrated on the flexible substrate 31; The bottom of the flexible substrate 31 is integrated with a temperature sensing array module 33 , which is in direct contact with the dressing body 1 . The bottom of the flexible packaging shell 34 is packaged at the outer edge of the temperature sensing array module 33 .

[0040] The dressing body 1 at the bottom of the temperature sensing array module 33 is provided with a plurality of temperature sensing through holes 4 distributed in a rectangular array. The interior of the temperature sensing through holes 4 is filled with a columnar heat conducting part 2 made of a polyvinyl alcohol / thermal conductive silicone composite material.

[0041] The monitoring module 3 and the dressing body 1 are detachably connected, and the top surface of the dressing body 1 is directly connected or the recessed portion 11 on the top surface thereof is engaged with the flexible packaging shell 34; The flexible packaging shell 34 is detachably connected to the dressing body 1 via the connecting piece 341 .

[0042] The temperature sensing array module 33 includes multiple metal semiconductors distributed in a rectangular array, and the metal semiconductors correspond one-to-one to the columns constituting the heat conducting portion 2 .

[0043] Each small metal semiconductor contact can sense the temperature fluctuations on the closely fitted patient skin surface, forming real-time voltage changes in the wound, which are converted into a thermal map image in the background.

[0044] The metal semiconductor material is nickel oxide, indium tin oxide or a composite thereof.

[0045] The thin film battery 32 provides power for the temperature sensor array module 33, the Bluetooth communication module and the control cache chip; The metal semiconductor on the temperature sensor array module 33 transmits real-time temperature-voltage data to the background system via the Bluetooth communication module, wherein the control cache chip serves as a data transfer station.

[0046] The thin film battery 32 is configured to support three to five days of data transmission usage.

[0047] Example 2 like Figure 3 and 4 As shown, a through hole for the pipe to enter and exit is opened at the center of the dressing body 1, and the same through hole is also opened at the corresponding position on the monitoring module 3; A protective component is provided, wherein the protective component covers the top of the through hole.

[0048] The protective assembly includes a truncated cone-shaped protective shell 51, which is fixed to the top of the through hole on the flexible packaging shell 34 or the top of the through hole on the dressing body 1; The annular surface on the top of the protective shell 51 is connected to the elastic clamping ring 52 through a soft connecting ring 53. The centers of the protective shell 51, the connecting ring 53 and the clamping ring 52 are all on the same vertical line, and an interference fit is formed between the clamping ring 52 and the pipe.

[0049] The clamping ring 52 is made of elastic medical-grade silicone material.

[0050] The present invention provides an elastic clamping ring structure at the peritoneal dialysis tube outlet. The ring-shaped design can closely fit the outer wall of the peritoneal dialysis tube. The elastic material's inherent resilience forms a reliable interference fit, effectively securing the tube at the outlet. Compared with existing technologies, this structural design has the following advantages: Effectively prevent catheter displacement: The elastic clamp stably clamps the catheter to prevent catheter displacement due to changes in patient position, turning over, activity or accidental pulling, reducing the risk of mechanical stimulation and tension injury at the exit site.

[0051] Reduce exit bleeding and tissue damage: By stabilizing the position of the catheter, repeated tearing, bleeding, redness, swelling or granulation tissue hyperplasia of the exit wound caused by frequent pulling can be avoided, which is conducive to the continuous and smooth healing of the exit wound and improves the long-term use safety of the peritoneal dialysis channel.

[0052] Improve patient comfort and compliance: The elastic clasp is soft and fits well, does not increase local tenderness or foreign body sensation in patients, has good adaptability, is suitable for different catheter models and body surface anatomical differences, is highly comfortable to wear for a long time, and improves the patient's wearing experience.

[0053] Simple structure and easy to use: The clamping ring has a simple structure, is easy to produce and process, and is easy to install and operate. It can be quickly fixed and disassembled, making it convenient for nursing staff to carry out daily care and cleaning, thereby improving nursing efficiency.

[0054] Compatible with a variety of nursing auxiliary materials: The clamp ring of the present invention can be used in conjunction with other nursing materials such as smart dressings, disinfected dressings, antibacterial coatings, etc. to form a comprehensive outlet management solution and improve the overall nursing quality.

[0055] Prevention of complications: By effectively buffering and dispersing the stress on the catheter outlet, it helps prevent common complications such as peritoneal dialysis outlet infection, outlet hernia, and abnormal proliferation of granulation tissue, thereby extending the service life of the peritoneal dialysis channel.

[0056] Example 3 The system also includes an algorithm evaluation system, wherein the algorithm module in the algorithm evaluation system collects the user's baseline thermal data in advance, analyzes it based on the neural network visual model and the comparison algorithm, and outputs a thermal map and abnormal warning information; The formula of the comparison algorithm is as follows:

[0057] in, Ti , j Indicates the i Rank j The temperature state of the column pixel, Vi , j Indicates the voltage value at this point. V threshold is the set voltage threshold, which is determined according to the voltage range corresponding to normal body temperature. The collected voltage matrix is converted into a temperature state matrix, and then a neural network visual model is used for image processing and analysis to generate a thermal map. The thermal map is then compared with the normal body temperature thermal map to determine the wound healing status.

[0058] The algorithm evaluation system uses U-Net or Vision Transformer deep learning models to reconstruct heat maps.

[0059] The algorithm module is based on pre-collected baseline test data and uses a neural network visual model to design a comparison formula. When the skin wound is healing well, the collected temperature is relatively uniform and within the normal range. If inflammation occurs, the local temperature is high. The algorithm module is used to monitor the wound healing condition.

[0060] The algorithm evaluation system processes data as follows: 1. Data preprocessing steps: Step S1: Data collection → Each contact (e.g., 5x5 array) corresponds to a temperature / voltage value, forming a frame of raw data matrix; Step S2: remove burrs and noise (using wavelet transform or Kalman filtering); Step S3: Arrange according to the time axis to form a multi-frame thermal data sequence.

[0061] 2. Neural Network Heatmap Generation Model: Structure: Use U-Net or Vision Transformer (ViT) structure to visually encode the data matrix; Training data: normal skin temperature, wound healing, and infection status are used as three labels; Output: Generate RGB image heat map (can be superimposed with skin image); Highlights: Abnormally high temperature areas are automatically marked in red, and normal areas are gradually changed from green to yellow.

[0062] 3. Steps of the efficacy judgment algorithm: Step Description E1 reads the latest frame of thermal data (Temp[x][y]); E2 is compared point by point with the user's individual baseline (normal thermal data is reserved); E3 calculates ΔT = current value - baseline value; E4 If local ΔT > a℃ and area > b contact → determine abnormal area; E5 outputs diagnosis results according to risk level: "normal / suspected infection / severe inflammation"; E6 automatically generates red, yellow, and green level prompts on the user interface or doctor's side.

[0063] Where a and b are the set judgment parameters.

[0064] Example 4 Preferably, the dressing body 1 is a dressing structure that changes color when exposed to liquid; like Figure 10 As shown, the dressing body 1 includes a bactericidal skin-friendly layer 14 and a transparent protective layer 15 , and a color-changing display layer 12 is provided between the bactericidal skin-friendly layer 14 and the protective layer 15 .

[0065] Specifically, the color-changing material in the color-changing display layer 12 is an embedded microcapsule structure, which breaks when encountering liquid to release dye to achieve color change.

[0066] Alternatively, the color-changing material is a water-sensitive color-changing dye or a pH-sensitive color-changing dye selected from hydroxyindoles, bromophenol blue, phenolphthalein, methyl orange, and the like.

[0067] Alternatively, a pattern or text is formed on the surface of the color-changing display layer 12, and the pattern or text is revealed or changes color when the leakage reaches a predetermined amount, forming a replacement prompt.

[0068] Alternatively, the transparent protective layer 15 is a moisture-permeable and waterproof medical polyurethane film.

[0069] At the same time, the color-changing display layer 12 is provided with a plurality of different color segments for corresponding to the alarm levels of different seepage amounts.

[0070] Compared with the prior art, the liquid-discoloring dressing structure proposed in the present invention has the following outstanding beneficial effects: Passive visual monitoring, accurate and intuitive Through the preset color-changing material structure, the color changes when the wound exudate reaches a certain level. Medical staff and patients can directly observe the color change through the transparent protective layer on the surface of the dressing, so that they can accurately judge the exudate status without the need for instruments, avoiding missed diagnosis or delayed replacement.

[0071] Simple structure, low cost, easy to mass produce It adopts the principle of pure physical and chemical reaction monitoring, does not require the use of complex sensors, electronic components or energy modules, has a mature manufacturing process, a wide range of raw materials, and low overall cost, making it particularly suitable for large-scale industrial production and universal medical promotion.

[0072] Dynamic alarm classification to prompt replacement time By designing multi-color segments or patterns, it can correspond to different degrees of exudate and provide graded alarms. Nursing staff can reasonably arrange the frequency of dressing changes according to the changes in color levels to avoid waste caused by saturated dressing leakage or premature replacement.

[0073] Improve nursing efficiency and patient safety It is convenient for nursing staff to quickly judge changes in wound exudate, reduce their labor intensity, improve nursing efficiency, and timely detect abnormal exudate to warn of infection risks, thereby improving patient healing quality and safety.

[0074] Good compatibility and scalability It can be integrated with intelligent temperature monitoring modules, catheter outlet fixing modules, etc. to achieve multi-dimensional integrated monitoring of wound exudate, temperature, catheter stability, etc., forming a systematic and intelligent overall wound care solution.

[0075] Adapting to diverse care environments Since the system does not require power and complex instruments, it is particularly suitable for nursing environments with limited human resources or insufficient equipment, such as primary medical institutions, home care, elderly rehabilitation centers and remote care, and will help promote the development of inclusive medical care.

[0076] In summary, the liquid-changing dressing structure provided by the present invention exhibits significant advantages in terms of ease of operation, cost controllability, efficient nursing, safety warning, and promotion and popularization, and has great clinical application value and market prospects.
