Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method and system for monitoring fluid exchange operation points of peritoneal dialysis patients based on blockchain technology. Background Art

[0002] With the continuous increase in the global incidence of chronic kidney disease (CKD), the number of patients with end-stage renal disease (ESRD) is growing, posing a severe challenge to social medical resources. Renal transplantation is the first choice for the treatment of end-stage renal disease. Although it has significant efficacy, most ESRD patients have to rely on dialysis to maintain their lives due to factors such as the shortage of donor organ resources, the difficulty of matching, and postoperative immune rejection. In dialysis treatment, peritoneal dialysis (PD) and hemodialysis (HD) are the two major methods. Among them, peritoneal dialysis has been widely used in clinical practice due to its advantages such as simple operation, better protection of residual renal function and higher quality of life of patients. It is especially suitable for self-management in a family environment. Peritoneal dialysis, especially "continuous ambulatory peritoneal dialysis at home" (CAPD), is a key means of renal replacement therapy for patients with end-stage renal disease (uremia). Its treatment effect is highly dependent on the regularity of follow-up and the standardization of patients' treatment.

[0003] However, the promotion of the home peritoneal dialysis model is also accompanied by a series of challenges. The primary problem is that it is difficult to ensure the standardization of patients' self-operation. The lack of immediate supervision by professional medical staff can easily lead to operational errors, which in turn increases the risk of serious complications such as peritonitis. In addition, the real-time collection and analysis of patients' dialysis data has become another major problem. Within the current technical framework, follow-up data mainly rely on paper documents manually recorded by patients. This method has significant problems such as lack of data synchronization, inconsistent data formats, and large differences in data representation. These problems seriously hinder the accurate collection of CAPD patient operation data, resulting in confusion in the follow-up timeline, and difficulty in implementing intervention measures in a timely manner, which may ultimately increase the risk of complications. It is difficult for medical staff to obtain key parameters in the patient's dialysis process in a timely and accurate manner, which affects the precise adjustment and effect evaluation of the treatment plan, and is not conducive to the long-term management and optimization of the patient's condition.

[0004] In response to the above dilemma, a peritoneal dialysis patient fluid exchange operation point monitoring system based on blockchain technology came into being, providing an innovative solution for home peritoneal dialysis management. The system deeply integrates cutting-edge information technologies such as the Internet of Things, big data analysis and blockchain, and realizes remote monitoring and intelligent management of patient dialysis operations. Specifically, by embedding smart sensors in dialysis equipment, the system can capture and record key data in the fluid exchange process in real time, including but not limited to dialysate flow, temperature, pressure changes and patient vital signs information. After these data are encrypted using blockchain technology, the security and immutability of data transmission are ensured, effectively preventing the risk of data leakage or tampering.

[0005] More importantly, the blockchain-based monitoring system can also realize real-time data analysis and feedback. Once abnormal operation or potential signs of complications are found, the system will immediately trigger the early warning mechanism, send operation instructions or emergency medical advice to the patient, and automatically notify medical staff for rapid intervention. This innovative model not only significantly improves the patient's self-management ability and safety, but also greatly enhances the communication and collaboration efficiency between doctors and patients, opening up new ways to optimize dialysis treatment strategies, reduce complications, and improve the overall quality of life of patients.

[0006] Therefore, technical personnel in this field are committed to developing a method and system for monitoring the fluid exchange operation points of peritoneal dialysis patients based on blockchain technology, aiming to timely, accurately and efficiently monitor the fluid exchange operation point data of peritoneal dialysis patients and promote high-quality development in the field of home peritoneal dialysis. Summary of the invention

[0007] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to solve how to timely, accurately and efficiently monitor the fluid exchange operation point data of peritoneal dialysis patients in a home peritoneal dialysis scenario.

[0008] To achieve the above objectives, on the one hand, the present invention provides a method for monitoring fluid exchange operation points of peritoneal dialysis patients based on blockchain technology, the method comprising:

[0009] Step 1: Any patient undergoing peritoneal dialysis uploads weight, blood pressure, and urine volume data;

[0010] Step 2, the patient records the peritoneal dialysis process monitoring data, and uploads the peritoneal dialysis process monitoring data to the server, and the server stores the patient's peritoneal dialysis process monitoring data;

[0011] Step 3, using the stored peritoneal dialysis process monitoring data to generate summary information, and adding the meta-information of the patient's current monitoring data to store it in the blockchain;

[0012] Step 4, calculating whether the received peritoneal dialysis process monitoring data is invalid data, if it is invalid data, no processing is performed; if it is valid data, the server performs noise reduction processing on the peritoneal dialysis process monitoring data, and calculates the data point position according to the sequential ID of the timestamp, and stores the calculated patient peritoneal dialysis process point data;

[0013] Step 5: The server calculates the patient's operation time data through the point information; and stores the calculated patient's peritoneal dialysis process time data;

[0014] Step 6: Generate summary information from the stored peritoneal dialysis process point data and process duration data, and store it in the blockchain together with the patient's meta-information of this monitoring data;

[0015] Step 7: The data point map and point details are available for doctors to review and analyze.

[0016] Furthermore, the points in step 4 include a starting point, a plug breaking point, a liquid inlet starting point, a liquid inlet end point, a tube sealing starting point, and a waste liquid hanging point at the tube sealing end point.

[0017] Furthermore, the patient operation time data in step 5 includes total operation time, hand hygiene time, liquid discharge time, tube sealing time, and liquid inlet time.

[0018] Furthermore, in step 3, the patient records the peritoneal dialysis process monitoring data. Specifically, the patient uses Bluetooth to connect to a spring scale to record the peritoneal dialysis process monitoring data.

[0019] Furthermore, the specific method in step 2 also includes that the server stores the patient's peritoneal dialysis process monitoring data in a relational database.

[0020] Furthermore, in step 4, it is calculated whether the received peritoneal dialysis process monitoring data is invalid data. The judgment condition is that when the data points are less than 1200 or the points do not meet the time sequence, they are regarded as invalid data.

[0021] Furthermore, in step 4, the specific method also includes storing the calculated patient peritoneal dialysis process point data in a relational database.

[0022] Furthermore, the specific method in step 5 also includes storing the calculated patient peritoneal dialysis process duration data in a relational database.

[0023] Furthermore, the specific method in step 7 also includes that the data point map and point details can be used by doctors to view and analyze the patient's home peritoneal dialysis operation specifications so as to provide timely advice and guidance.

[0024] On the other hand, the present invention provides a peritoneal dialysis patient fluid exchange operation point monitoring system based on blockchain technology, which has a functional module for executing any of the aforementioned peritoneal dialysis patient fluid exchange operation point monitoring methods based on blockchain technology.

[0025] Furthermore, the functional modules include a patient end, a data uploading module, a data receiving module, a peritoneal dialysis process point calculation service, a peritoneal dialysis process duration calculation service, a medical end, a peritoneal dialysis process monitoring database, and a peritoneal dialysis process monitoring summary blockchain.

[0026] Furthermore, the patient end provides patients with the function of viewing and uploading data. Patients can upload data through the data upload module. The uploaded data includes but is not limited to one or more of body weight, blood pressure, urine volume, peritoneal dialysis fluid weight, and peritoneal dialysis process point data.

[0027] Furthermore, the medical end provides doctors with data analysis for managing peritoneal dialysis patients and patients' peritoneal dialysis processes, timely discovers patient abnormalities or risks, and provides assistance and intervention; the medical end receives data through a data receiving module and calculates the patient's peritoneal dialysis point information and duration information through a peritoneal dialysis process point calculation service and a peritoneal dialysis process duration calculation service, and records relevant data in the data receiving module, the peritoneal dialysis process point calculation service, and the peritoneal dialysis process duration calculation service to a peritoneal dialysis process monitoring database, and stores data metadata and data summary information in a peritoneal dialysis process monitoring summary block.

[0028] The blockchain-based peritoneal dialysis patient fluid exchange operation point monitoring method and system provided by this patent allows patients to perform dialysis in their familiar home environment, and can effectively introduce medical resources for care and guidance of daily home fluid exchange operations. Patients can arrange dialysis time according to the medical plan formulated by the doctor, without the need to frequently travel to and from the hospital. This is especially convenient for patients with limited mobility or living in areas far from the hospital. Patients will feel more comfortable and relaxed when undergoing dialysis at home, and can better adapt to dialysis life and reduce the tension and anxiety that may arise from dialysis in the hospital. This patent reduces the chances of patients being exposed to the hospital environment and reduces the risk of cross-infection to a certain extent.

[0029] Secondly, this patent fully considers the problems that patients may encounter during home peritoneal dialysis, such as lack of direct medical supervision, difficulty in ensuring operational standardization, and high risk of peritonitis. By combining the WeChat applet with the doctor management end, patients can use the WeChat applet to monitor, record and upload the data process. The doctor end can automatically discover the patient's operational standardization problems in real time based on the point algorithm, communicate and guide the patient in a timely manner, effectively reduce the various problems and risks encountered by patients during home peritoneal dialysis, and automatically collect the patient's peritoneal dialysis data at the same time, and make timely adjustments and interventions according to the situation.

[0030] Finally, this patent adopts the advantages of decentralized storage, data encryption, anonymization processing, access control, data immutability and traceability of blockchain technology, and stores the patient's data in multiple nodes in a dispersed manner, avoiding the risk of single point failure and centralized data theft; at the same time, the traceability of blockchain enables every data access, modification and other operations to be accurately recorded, forming a complete audit tracking chain, so that patients and relevant regulatory agencies can view the data operation history at any time, and promptly discover problems such as abnormal access and data leakage, thereby enhancing the protection of patient privacy.
