Description

Technical Field

[0001] The present invention relates to the technical field of wound treatment, and in particular to a wound repair method and system combining traditional Chinese medicine with VSD drainage. Background Art

[0002] The field of wound care technology focuses on the management and treatment of wounds, ranging from basic wound cleaning and protection to medical interventions such as promoting tissue regeneration and controlling infection. This field utilizes a variety of medical technologies, including traditional dressings, antibiotic application, surgical techniques, and modern technologies such as negative pressure wound therapy and bioengineered materials. The goal of wound care is to accelerate wound healing, reduce complications, and improve the patient's quality of life.

[0003] Among them, the wound repair method combining traditional Chinese medicine and VSD drainage is an innovative wound treatment program that combines the treatment concepts of traditional Chinese medicine and modern medical technology. The method is mainly used to treat chronic and difficult-to-heal wounds, such as diabetic foot ulcers or long-term pressure sores. Traditional Chinese medicine is used in this program for its blood circulation and anti-inflammatory properties, while VSD drainage technology promotes wound drainage through negative pressure, reduces the chance of infection, and accelerates healing. The purpose of the method is to achieve more efficient wound cleaning and healing effects through the combination of traditional Chinese and Western medicine, especially in the treatment of difficult-to-heal wounds that are difficult to treat with traditional methods.

[0004] When selecting Chinese medicine, traditional repair methods rely on the experience and judgment of medical staff themselves, resulting in medical staff with different experiences finding it difficult to choose the best Chinese medicine repair solution for repair quality. Cost factors are not taken into consideration, leading to excessive or improper use of high-cost treatment options. In the selection process of the VSD device, only based on experience judgment, the VSD device may be too large, which is not only too expensive but also affects the treatment effect. The time for removing the VSD device also depends on the experience and judgment of medical staff. It is difficult to adjust the treatment plan according to the progress of wound healing, resulting in treatment delays or inappropriate continuation of treatment, increasing patient discomfort and treatment costs. Summary of the invention

[0068] See also Figure 2 , the method to identify the wound edge position is:

[0069] S111: Based on the wound surface of the patient, an image of the wound surface is captured by an image capturing device, and the image quality is optimized by preprocessing the image to obtain wound surface image information;

[0070] S112: Based on the wound surface image information, the formula:

[0071]

[0072] Calculate the gradient strength S of the pixel, where k1 and k2 are weighting coefficients, G x and G y are the gradients of the pixel in the horizontal and vertical directions respectively, and S is the gradient strength of the pixel;

[0073] S113: Based on the gradient strength S of the pixel point, the pixel point with a gradient strength exceeding the preset gradient threshold is compared with the preset gradient threshold, and the pixel point is marked as a wound edge to obtain a wound edge marking result.

[0074] formula:

[0075]

[0076] The meaning and acquisition method of parameters:

[0077] G x and G y : The parameters represent the gradient of the pixel in the horizontal and vertical directions. The gradient is the rate of change of the image brightness and is calculated by using the Sobel operator. Before processing the image, the image first goes through a preprocessing stage where a Gaussian filter is applied to remove noise. Then the Sobel operator is used to apply horizontal and vertical masks to the filtered image to obtain the G x and G y .

[0078] k1 and k2: weighting coefficients used to adjust the horizontal and vertical gradients G x and G y The influence of the coefficients in the calculation of the final gradient strength S. The coefficients can be adjusted according to the specific characteristics of the image to optimize the edge detection effect. In practical applications, the selection of coefficients depends on the specific analysis of the image content or is set through expert experience.

[0079] Calculation example:

[0080] Set the following parameters:

[0081] G x =120 and G y =100: represents the horizontal and vertical gradient values ​​of a pixel.

[0082] k1=0.8 and k2=0.7: coefficients for adjusting the gradient influence.

[0083] Set the gradient strength threshold to 150.

[0084] Calculate the gradient strength S:

[0085]

[0086] The calculated result S≈118.81 is less than the gradient intensity threshold of 150, so the pixel is not considered as the wound edge.

[0087] See also Figure 3 , the steps to obtain the wound size assessment results are:

[0088] S121: Based on the wound edge marking result, the total number of pixels in the wound area is extracted through image analysis, and the formula is:

[0089] A=N·a D

[0090] Calculate the wound area A, where N represents the number of pixels in the wound area, a D is the area scaling factor;

[0091] S122: Based on the wound area A and the wound shape, the formula is:

[0092]

[0093] Calculate the wound size index D to obtain the wound size assessment result, where A represents the wound area, k D is the shape coefficient, C represents the curvature of the wound edge, α D is the exponential adjustment factor, β D is the base offset of curvature, γ D is the standardized coefficient, D is the wound size index, and e is the base of the natural logarithm.

[0094] formula:

[0095] A=N·a D

[0096] and

[0097]

[0098] The meaning and acquisition method of parameters:

[0099] N: The number of pixels in the wound area, which indicates the total number of pixels at the edge of the wound that have been marked in the image. It is automatically counted by the image processing software.

[0100] a D: represents the area scaling factor, that is, the actual area represented by each pixel. The specific value depends on the resolution of the image and the specific parameters of the imaging device. For example, if a pixel represents 0.1 square millimeters in actual measurement, then a D 0.1mm 2 .

[0101] k D : Shape coefficient is an adjustment parameter that is set according to the regularity and complexity of the edge shape of the wound surface. It can be set based on previous clinical data or through the experience of experts.

[0102] C: The curvature of the wound edge is obtained through geometric analysis of the edge shape, indicating the degree of tortuosity of the edge curve. It is usually automatically calculated by the geometric algorithm in the image analysis software.

[0103] α D , β D and γ D :α D is the exponential adjustment factor, β D is the base offset of curvature, γ D It is a normalization coefficient, which is set by experts to optimize the range and rate of change of the calculation results.

[0104] Calculation example:

[0105] Set the following parameter values:

[0106] N=500: represents the number of pixels.

[0107] a D =0.1mm 2 : The actual area represented by each pixel.

[0108] k D =0.5: shape factor, set according to the general complexity of the wound surface.

[0109] C=0.3: edge curvature, obtained through image analysis.

[0110] α D =2: Curvature influence adjustment factor.

[0111] β D =0.25: Baseline offset of curvature.

[0112] γ D =100: coefficient used to normalize the results.

[0113] Calculate the total wound area A:

[0114] A=N·a D =500·0.1=50mm2

[0115] Calculate the wound size index D:

[0116]

[0117] The calculation result D≈0.726 represents the wound size score after the given shape coefficient and curvature are adjusted. The larger the value, the larger the wound.

[0118] See also Figure 4 , the method for identifying the Chinese medicine repair fluid that matches the current wound surface is:

[0119] S211: extracting the characteristics of the current wound based on the wound size assessment result, the characteristics of the current wound including wound depth, body part, wound type and wound size index;

[0120] S212: Based on the characteristics of the current wound surface, extract the applicable data of differentiated Chinese medicine repair fluids, including the applicable wound depth, applicable site, applicable wound type and applicable wound size corresponding to each Chinese medicine repair fluid, through the formula:

[0123] S213: Based on the matching score M, compare with the preset matching threshold, mark the traditional Chinese medicine repair liquid whose matching score exceeds the preset threshold, and obtain the matching traditional Chinese medicine repair liquid identification result.

[0124] formula:

[0125]

[0126] The meaning and acquisition method of parameters:

[0127] d: Wound depth, usually measured directly by medical staff using professional tools or obtained through imaging examinations.

[0128] P: The part of the body where the wound is located, recorded based on the medical staff's observation or the patient's description.

[0129] T: Wound type, such as abrasion, cut, etc. This information is determined and recorded by medical staff based on the appearance of the wound.

[0130] D: Wound size index, calculated by the previous method.

[0131] d m , P m , T m and D m : The parameters represent the depth, location, type and size of wounds that the Chinese medicine repair fluid is suitable for. The information is provided by the historical usage data of the Chinese medicine repair fluid or the manufacturer.

[0132] w d 、w p 、w t and w s : Weight coefficient, adjusted according to the medical team's experience or historical data to balance the influence of different characteristics in the matching score.

[0133] δ(P,P m ) and δ(T, T m ): Difference function, when P = P m Or T = T m It returns 0 when the value is true, otherwise it returns 1. It is used to calculate the match between the two parameters.

[0134] Calculation example:

[0135] Set the following parameter values:

[0136] The current wound depth is d = 2cm, the location is P = "arm", the type is T = "cut", the size is D = 15, and the Chinese medicine repair solution is suitable for: depth d m =3cm, part P m = "Legs", Type T m = "Cut", size D m =10, the weight coefficient is set to: w d =0.5, w p =0.3, w t =0.2, w s =0.4.

[0137] Calculation process formula:

[0138]

[0139] The calculated result M≈23.26 indicates the matching score between the Chinese medicine repair fluid and the current wound surface. The matching degree is low, which is mainly caused by the difference in body parts and sizes. The results show that the Chinese medicine repair fluid may not be the most ideal choice. Medical staff should consider using a more matching repair fluid to improve the treatment effect.

[0140] See also Figure 5 , the steps to obtain the results of Chinese medicine repair are:

[0141] S221: Based on the matching results of the Chinese medicine repair solution, combined with the cost of each Chinese medicine repair solution, the formula is:

[0143] Calculate the profit score R of each Chinese medicine repair solution, where ξ R is the weight coefficient, λ R is the regularization coefficient, M is the matching score, B is the cost of the Chinese medicine repair solution, and R is the benefit score of the Chinese medicine repair solution;

[0144] S222: Based on the benefit score R of the traditional Chinese medicine repair fluid, by comparing the benefit scores of differentiated traditional Chinese medicine repair fluids, select the target traditional Chinese medicine repair fluid, and repair the wound surface through medical staff to obtain the traditional Chinese medicine repair result.

[0148] M: Matching score, calculated in the previous step.

[0149] B: The cost of Chinese herbal repair fluid is usually obtained through the hospital's purchasing department or directly from the supplier's quotation, ensuring the accuracy and timeliness of the cost data.

[0150] ξ R : is a weight coefficient used to enhance the role of the fit score in the benefit score calculation. It can be dynamically adjusted based on historical data and clinical feedback to optimize the sensitivity and specificity of the scoring model.

[0151] λ R : Regularization coefficient, mainly used to deal with the excessive impact on the score when the cost is extremely low. The value of this parameter is usually set according to the cost distribution of traditional Chinese medicine repair fluid in the past to ensure the balance of the benefit score.

[0152] Calculation example:

[0153] Set the following values:

[0154] M = 85: high matching score, indicating that the Chinese medicine repair fluid is very consistent with the current wound condition, B = 200: cost unit is yuan, ξ R =1.5: weighting factor, λ R =10: Regularization coefficient.

[0155] Calculation process:

[0156]

[0157] The calculated benefit score R≈1.233, and the larger the value is, the better the comprehensive effect of the traditional Chinese medicine repair fluid is.

[0158] See also Figure 6 , the steps to obtain the results of negative pressure suction are:

[0159] S311: Based on the results of Chinese medicine repair and wound size assessment, according to the wound size index and wound area, the formula is:

[0160]

[0161] Calculate the selectivity index I of the VSD device, where κ I is the adjustment parameter, D is the wound size index, A is the wound area, and A m is the applicable area range of the VSD device, and I is the selection index;

[0167] A: Wound area, calculated using the previous method.

[0168] A m : The applicable area range of the VSD device is indicated in the product specifications provided by the manufacturer. This parameter indicates the applicable range of each VSD model in terms of wound area, which is usually obtained by referring to the product manual.

[0169] κ I: It is an adjustment parameter used to balance the influence between wound score D and area adaptability A, ensuring the effect under different wound areas and complexities.

[0170] Calculation Example

[0171] Set the following parameter values:

[0186] Δ h : Health status difference, which indicates the difference in health status score between the current patient and similar cases. The health status score is assessed by experts based on the patient's overall health status and chronic disease history, and the difference value is expressed by the difference between the two health scores.

[0187] α T : The weight coefficient of age difference is used to adjust the effect of age on recovery time. This coefficient is obtained by analyzing large sample historical data. Regression analysis or correlation analysis is usually used to determine its reasonable range to ensure the accuracy of recovery time prediction.

[0188] β T : Weight coefficient of health status difference, used to adjust the impact of health status on recovery time. This coefficient is set in combination with the correlation between health status score and recovery time to ensure the scientific nature of recovery time prediction.

[0189] Δ s : Wound severity difference, which indicates the difference in severity between the current wound and similar cases. Wound severity is assessed by experts.

[0190] γ T: The weight coefficient of wound severity is used to adjust the impact of wound complexity on recovery time. This coefficient is obtained through the correlation analysis of wound complexity and recovery time in historical data to ensure the rationality of the coefficient.

[0191] Calculation example:

[0192] Set the following values: Average recovery time T for similar patients r = 3 days, age difference Δ a =10 years old, health status difference Δ h =0.2, indicating that there is a small difference in health score and a small difference in wound severity Δ s =0.3, indicating that there are slight differences in the severity of the wound surface, and the weight coefficient of age difference α T =0.05, weight coefficient of health status difference β T =0.1, weight coefficient of wound severity γ T =0.15.

[0193] Calculation process:

[0194] T=T r ·(1+α T Δ a +β T Δ h )·(1+γ T Δ s )

[0195] =3·(1+0.05·10+0.1·0.2)·(1+0.15·0.3)

[0196] =3·(1+0.5+0.02)·(1+0.045)

[0197] =3·1.52·1.045

[0198] ≈4.7562

[0199] The calculated predicted recovery time T≈4.76 days means that after considering the differences in age, health status and wound severity between the current patient and similar patients, the estimated time required to recover to the target effect will be longer than the original 3 days. The results can help medical staff make reasonable estimates of the recovery process and adjust treatment plans accordingly.
