[0002] As one of the important means for treating end-stage renal disease, peritoneal dialysis has been widely used clinically due to its relatively simple operation and less impact on the patient's hemodynamics. During peritoneal dialysis, the patient uses their own peritoneum as a semipermeable membrane, and by instilling dialysate into the abdominal cavity, the removal of metabolic waste and excess water in the body is achieved. However, there are risks that cannot be ignored in this treatment method, among which tunnel infection and peritonitis are the most common and serious complications.

[0030] Working principle: The overall device takes the operation box as the core. When the bidirectional lead screw on its outer wall rotates, it can drive the clamping blocks with sliders to move relatively or away from each other, and realizes the stable fixation of the dialysis pipeline and the like by means of the ejector pin and the spring.

It solves the problem of incomplete disinfection.

[0035] 3. The present invention provides a clear guiding path for dialysis pipelines and the like through the guiding tube, making it difficult for the pipelines to be distorted or entangled during the fixing process, ensuring the smooth flow of the liquid inside the pipelines. At the same time, the capping function of the cap on the guiding tube when not in use can effectively protect the inside of the guiding tube and the pipelines passing through the guiding tube, prevent external pollutants from entering, and reduce the risk of infection. It solves the problem that the pipelines are easily contaminated.

[0036] 4. The present invention obtains key parameter information such as the temperature, pH value, and osmotic pressure of peritoneal dialysis fluid in real time, forms continuous data records, presents the dynamic changes of each parameter of the dialysis fluid during the entire dialysis process for medical staff, facilitates them to accurately grasp the real-time state of the dialysis fluid, and provides reliable data support for subsequent analysis, evaluation, and regulation work.

Specific implementation mode

[0051] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] Please refer to the attached Figure 1 - attached Figure 5 , an embodiment of the present invention provides a device for preventing peritoneal dialysis tunnel infection or peritonitis, including an operation box 1. The outer wall of the operation box 1 is rotatably connected to a bidirectional lead screw 20. One end of the bidirectional lead screw 20 is fixedly provided with a handle 1 4. The middle parts of both ends of the bidirectional lead screw 20 are threadedly connected with clamping blocks 22. The thread directions on the outer wall of the bidirectional lead screw 20 are opposite. Both side walls of the clamping block 22 are fixedly provided with slide blocks 21. The top ends of the slide blocks 21 are slidably connected to the top end inner wall of the operation box 1. One side of the clamping block 22 is provided with a plurality of thrust columns 23. One end of the thrust column 23 is provided with a spring 24. The spring 24 is arranged inside the clamping block 22. The top end of the operation box 1 is provided with a bearing groove, and a disinfection device is arranged in the bearing groove of the operation box 1.

[0053] Specifically, rotating the handle 4 drives the bidirectional lead screw 20 fixedly connected thereto to rotate. Since the thread directions on the outer wall of the bidirectional lead screw 20 are opposite, and clamping blocks 22 are threadedly connected to both ends of the middle part thereof, according to the principle of screw drive, when the bidirectional lead screw 20 rotates, the two clamping blocks 22 will move relatively or away from each other along the lead screw. The sliders 21 fixed to both side walls of the clamping blocks 22 slide on the top end of the inner wall of the operation box 1, playing a guiding role to ensure the smoothness and accuracy of the movement of the clamping blocks 22. During the movement of the clamping blocks 22, a number of ejector pins 23 on one side of the clamping blocks 22 will move accordingly. When the clamping blocks 22 move towards the objects to be fixed, such as dialysis tubes, the ejector pins 23 will contact the objects. Since a spring 24 is provided at one end of the ejector pin 23, the spring 24 will generate elastic deformation when being squeezed. According to Hooke's law, the elastic force generated by the spring 24 will make the ejector pin 23 tightly press against the object, thereby realizing the clamping and fixing of the object.

[0054] By rotating the handle 4 to control the movement of the clamping blocks 22 and utilizing the cooperation of the ejector pins 23 and the springs 24, flexible and stable clamping and fixing can be achieved for objects such as dialysis tubes with different sizes and shapes. The elastic action of the springs 24 can adapt to the minor deformation and position change of the objects, and always maintain a certain clamping force to ensure that the dialysis tube does not shake or shift during peritoneal dialysis, guaranteeing the smooth progress of dialysis treatment. The problem of unstable fixation is solved.

[0055] Please refer to the attached Figure 1 - attached Figure 3 , the disinfection device includes a disinfectant solution box 3. The bottom end of the disinfectant solution box 3 is arranged in the bearing groove of the operation box 1. A liquid inlet valve 2 is arranged on the upper surface of the disinfectant solution box 3. A liquid storage cavity 14 is arranged inside the disinfectant solution box 3. An outlet valve 16 is arranged at the bottom end inside the disinfectant solution box 3. One end of the outlet valve 16 is provided with a connecting pipe 18. Spray pipes 17 are arranged on the outer walls at both ends of the connecting pipe 18. The outlet valve 16 and the connecting pipe 18 are arranged in the bearing groove of the operation box 1. The outer wall of the spray pipe 17 penetrates through the operation box 1 and is arranged inside the operation box 1. An integrated controller 19 is arranged in the bearing groove of the operation box 1. Fixed components are arranged on both sides of the operation box 1.

[0056] Specifically, the disinfectant liquid is injected into the liquid storage cavity 14 inside the disinfectant liquid box 3 through the liquid inlet valve 2 for storage. The liquid inlet valve 2 controls the inflow of the disinfectant liquid. When it is necessary to add the disinfectant liquid, the liquid inlet valve 2 is opened, and the disinfectant liquid enters the liquid storage cavity 14 under the action of gravity or an external pressure. After the addition is completed, the liquid inlet valve 2 is closed to prevent the leakage of the disinfectant liquid. When a disinfection operation is required, an instruction is issued through the integrated controller 19 in the carrier slot of the operation box 1 to control the opening of the liquid outlet valve 16. The disinfectant liquid in the liquid storage cavity 14 flows out from the liquid outlet valve 16 under its own gravity or under the action of a certain pressure difference and enters the connecting pipe 18. The disinfectant liquid flowing into the connecting pipe 18 is evenly sprayed out through the spray pipes 17 provided on the outer walls at both ends of the connecting pipe 18 by means of the flowing pressure of the liquid. The spray pipes 17 penetrate through the operation box 1 and are arranged inside it, enabling the disinfectant liquid to directly act on the inside of the operation box 1 and the parts related to peritoneal dialysis, so as to achieve the disinfection treatment of this area.

[0057] Through the precise control of the liquid outlet valve 16 by the integrated controller 19, the on-demand output of the disinfectant liquid can be achieved. The design of the connecting pipe 18 and the spray pipes 17 enables the disinfectant liquid to be evenly sprayed inside the operation box 1 and related parts, ensuring the comprehensiveness and uniformity of disinfection, improving the disinfection efficiency, and effectively killing pathogens such as bacteria and viruses in this area. The problem of incomplete disinfection is solved.

[0058] Please refer to the appendix Figure 1 - appendix Figure 2 , the fixing assembly includes a breathable strap one 5. One end of the breathable strap one 5 is arranged on the side wall of the operation box 1. A hook-and-loop fastener rough surface 6 is arranged at one end of the breathable strap one 5. A hook-and-loop fastener hook surface 8 is arranged on one side of the hook-and-loop fastener rough surface 6. A breathable strap two 9 is arranged at the top of the hook-and-loop fastener hook surface 8. One end of the breathable strap two 9 is arranged on the other side of the operation box 1. A guide pipe 11 is fixedly arranged on the side wall of the operation box 1. A thread is arranged on the outer wall of the guide pipe 11, and a cap 10 is threadedly connected to the thread of the guide pipe 11.

[0059] Specifically, one end of the breathable strap one 5 is connected to one side wall of the operation box 1, and the other end is provided with a hook-and-loop fastener rough surface 6; one end of the breathable strap two 9 is connected to the other side wall of the operation box 1, and the other end is provided with a hook-and-loop fastener hook surface 8. When it is necessary to fix the device on the patient's body, the breathable strap one 5 and the breathable strap two 9 are wound around the appropriate part of the patient's body, and then the hook-and-loop fastener rough surface 6 and the hook-and-loop fastener hook surface 8 are made to fit each other. Due to the hook-shaped structure of the hook-and-loop fastener hook surface 8 being able to tightly engage with the fluff structure of the hook-and-loop fastener rough surface 6, through this mechanical connection method, the fixed connection of the breathable strap one 5 and the breathable strap two 9 is realized, thereby stably fixing the operation box 1 on the patient.

[0060] The guiding tube 11 is fixedly arranged on the side wall of the operation box 1, and its outer wall is threaded. During peritoneal dialysis, the dialysis pipeline and the like can pass through the guiding tube 11, and the guiding tube 11 plays a role in guiding and positioning the pipeline, so that the pipeline can maintain an orderly position to a certain extent. When the guiding tube 11 is not needed, the cap 10 with internal threads is screwed onto the threads of the guiding tube 11. Through the screwing action of the threads, the cap 10 is tightly installed on the guiding tube 11, thereby closing the guiding tube 11 and preventing foreign matters such as dust and bacteria from entering.

[0061] The guiding tube 11 provides a clear guiding path for the dialysis pipeline and the like, so that the pipeline is not easily distorted or wound during the fixing process, ensuring the smooth flow of the liquid in the pipeline. At the same time, the closing effect of the cap 10 on the guiding tube 11 when not in use can effectively protect the inside of the guiding tube 11 and the pipeline passing through the guiding tube 11, prevent external pollutants from entering, and reduce the risk of infection. It solves the problem that the pipeline is easily contaminated.

[0062] Please refer to the attached Figure 2 - attached Figure 4 、 attached Figure 6 , a non-slip pad 12 is arranged at the bottom end of the operation box 1. A contact cavity 15 is arranged in the middle of the non-slip pad 12. A number of anti-slip silica gels 13 are arranged at the bottom end of the non-slip pad 12. A slot is arranged inside the non-slip pad 12. A cotton cloth box 25 is slidably connected in the slot of the non-slip pad 12. A handle two 26 is arranged on one side of the cotton cloth box 25. A cotton cloth groove 7 is arranged in the middle of the cotton cloth box 25.

[0063] Specifically, the non-slip pad 12 is located at the bottom end of the operation box 1, and the number of anti-slip silica gels 13 arranged at its bottom end has a large friction coefficient. When the operation box 1 is placed on the skin, the anti-slip silica gels 13 are in close contact with the contact surface. Relying on the elasticity of the silica gel itself and the friction force between the contact surface, the friction force between the operation box 1 and the placement plane is increased, thereby playing an anti-slip role. At the same time, the contact cavity 15 arranged in the middle of the non-slip pad 12 can fit the shape of the placement plane to a certain extent, further improving the tightness of the contact and enhancing the anti-slip effect.

[0064] A slot is provided inside the anti-slip mat 12, and the cotton cloth box 25 is slidably connected in the slot and can be pulled and moved along the slot. A handle 26 is provided on one side of the cotton cloth box 25. By holding the handle 26 and applying external force, the cotton cloth box 25 can be easily pulled out or pushed out of the slot. A cotton cloth groove 7 is provided in the middle of the cotton cloth box 25, which can be used to place cleaning supplies such as cotton cloth. When the disinfection device sprays disinfectant, some excess droplets of the sprayed disinfectant will fall. At this time, the cotton cloth box 25 is pulled out, and the cotton cloth can absorb these excess disinfectants by utilizing the water absorption of the cotton cloth, so as to avoid the patient from being flowed at will and causing discomfort. In addition, when the patient sweats, the cotton cloth box 25 can also be pulled out, and the patient's sweating part can be contacted with cotton cloth. With the good hygroscopicity of the cotton cloth, the sweat can be absorbed, and the patient's skin surface can be kept relatively dry, reducing the skin problems that may be caused by the accumulation of sweat and the influence on the dialysis operation.

[0065] The design of the cotton cloth box 25 being flexible and pullable makes it convenient for medical staff or patients to use the cotton cloth in the cotton cloth slot 7 for cleaning at any time according to actual needs. During disinfection, it can effectively absorb excess disinfectant, maintain the cleanliness of the surrounding environment, and prevent the adverse effects caused by excessive residual disinfectant; when the patient sweats, it can absorb sweat in time to ensure that the patient's skin is in a relatively comfortable and dry state, reduce the possibility of infection and other problems caused by sweat, and help maintain a good dialysis hygiene environment.

[0066] Please see attached Figure 7 -Attached Figure 12 , a system for preventing peritoneal dialysis tunnel infection or peritonitis, a device for preventing peritoneal dialysis tunnel infection or peritonitis, comprising the following modules:

[0067] Data acquisition module, used to collect the temperature, pH, osmotic pressure of peritoneal dialysis fluid and obtain the patient's key parameters such as body temperature, heart rate, and blood pressure;

[0068] Data analysis and risk assessment module, used to process and evaluate the data collected by the data acquisition module;

[0069] An intelligent control module is used to control the peritoneal dialysis process based on the results of the data analysis and risk assessment modules;

[0070] The early warning and feedback module is used to monitor whether the patient's dialysate has obvious abnormalities and to record and store previously collected data and risk assessment results;

[0071] The remote communication module is used to transmit the collected data to the terminal equipment of medical staff in real time and to push peritoneal dialysis-related knowledge and precautions to patients.

[0072] The data acquisition module includes:

[0073] The dialysate parameter monitoring sub-module is used to monitor the key parameters of peritoneal dialysis fluid temperature, pH value, and osmotic pressure in real time;

[0074] The patient physiological data acquisition sub-module is used to collect the patient's basic vital signs and the local peritoneal signs.

[0075] Specifically, the dialysate parameter monitoring sub-module is equipped with corresponding sensors, which detect the key parameters of peritoneal dialysis fluid based on different physical or chemical principles. For example, for temperature monitoring, a thermistor and other temperature sensors are used. Its resistance value changes with the change of the dialysis fluid temperature. By detecting the resistance change and according to a specific conversion formula, the real-time temperature value of the dialysis fluid can be obtained; for pH value monitoring, a pH electrode is relied on. It can undergo a specific chemical reaction with hydrogen ions in the dialysis fluid to generate a corresponding potential difference, and then convert the potential difference into the corresponding pH value according to principles such as the Nernst equation; for osmotic pressure monitoring, it is based on the detection of the solute concentration in the dialysis fluid. Through a specific osmotic membrane and related concentration sensing devices, the osmotic pressure value of the dialysis fluid is calculated according to the relationship between osmotic pressure and solute concentration. These sensors continuously contact the dialysis fluid and obtain data, and then transmit the collected data to the subsequent data processing unit in real time.

[0076] This sub-module uses a variety of medical monitoring devices to collect relevant data of the patient. In terms of basic vital signs, for example, heart rate monitoring is carried out through an electrocardiograph. Its electrodes are attached to the corresponding positions on the patient's body surface. By detecting the weak current changes generated by the electrical activity of the heart and according to the characteristic laws of electrocardiogram signals, the heart rate value can be calculated; blood pressure monitoring relies on an electronic sphygmomanometer. The cuff is used to apply pressure to parts such as the patient's arm, and then by detecting the fluctuation signals caused by the change of blood pressure in the blood vessels, the systolic blood pressure and diastolic blood pressure values are obtained according to a specific blood pressure calculation algorithm; body temperature monitoring relies on a thermometer (such as an electronic thermometer). The thermosensitive element is used to contact specific parts of the patient's body surface or inside (such as the armpit, mouth, etc.), and the patient's body temperature value is obtained according to the temperature change of the thermosensitive element. For the local peritoneal signs, for example, through ultrasonic examination equipment, palpation, etc. (some with pressure sensing devices, etc.) to detect the degree of local peritoneal swelling, tenderness, etc., and integrate and collect the data obtained from these examinations and transmit them to the subsequent analysis and processing link.

[0077] By obtaining the key parameter information such as the temperature, pH value, and osmotic pressure of peritoneal dialysis fluid in real time, continuous data records are formed, presenting the dynamic changes of each parameter of the dialysis fluid during the entire dialysis process for medical staff, facilitating them to accurately grasp the real-time state of the dialysis fluid and providing reliable data support for subsequent analysis, evaluation, and regulation work. It solves the problem of being unable to grasp the parameter state of the dialysis fluid in real time.

[0078] The data analysis and risk assessment module includes:

[0079] A dialysate status analysis sub-module, which is used to analyze the parameters of the collected dialysate, and judge whether there is an abnormal situation of the dialysate by comparing with the preset normal range standard;

[0080] A comprehensive patient infection risk assessment sub-module, which is used to comprehensively evaluate the risk of peritoneal dialysis tunnel infection or peritonitis in patients by combining the patient's physiological data and the analysis results of the dialysate status, and divide the corresponding risk levels.

[0081] Specifically, the dialysate status analysis sub-module will receive the parameter data of peritoneal dialysate collected by the dialysate parameter monitoring sub-module. These data cover key indicators such as temperature, pH value, and osmotic pressure. Then, the normal range standard values corresponding to each parameter are preset inside the sub-module, and these standard values are determined based on a large amount of medical research and clinical practice experience. For example, for the dialysate temperature, the normal range may be set within a specific interval (such as 36.5°C - 37.5°C); there is a corresponding appropriate interval for the pH value; the osmotic pressure also has a corresponding standard range.

[0082] After receiving the real-time dialysate parameter data, the sub-module will compare these actually collected data with the preset normal range standards one by one. Through the written logical judgment program, if the collected data falls within the normal range standard, it is determined that the corresponding parameter is in a normal state; if the data exceeds the upper and lower limits of the normal range, it is considered that the parameter has an abnormal situation. For example, if the collected dialysate temperature is 38°C, exceeding the upper limit of the set normal temperature interval, the system will determine that the temperature parameter is abnormal.

[0083] This sub-module will simultaneously obtain the patient's basic vital signs (such as heart rate, blood pressure, body temperature, etc.) and data on the local peritoneal signs collected by the patient physiological data collection sub-module, as well as the analysis results of the parameters of the dialysate output by the dialysate status analysis sub-module. Then, it uses a built-in evaluation algorithm constructed by a professional medical team and verified by a large number of clinical cases inside.

[0084] This set of algorithms comprehensively considers the correlation between different factors and the impact weight on the infection risk. For example, when multiple factors such as an increase in the patient's body temperature, local tenderness in the peritoneum, and abnormal pH of the dialysate occur simultaneously, compared with a single factor abnormality, a higher infection risk weight will be assigned in the algorithm. By substituting these input data into the evaluation algorithm for complex calculations and logical analyses, the risk level of the patient developing peritoneal dialysis tunnel infection or peritonitis is finally obtained, and the patient is classified into the corresponding risk level according to the pre-set risk level classification criteria (such as low risk, medium risk, high risk, etc.).

[0085] By achieving a comprehensive, scientific, and quantitative comprehensive assessment of the patient's infection risk, it no longer relies solely on the subjective experience of medical staff. The generated risk level assessment result can clearly reflect the current infection risk status of the patient, providing an intuitive and reliable reference index for medical staff. Based on this risk level result, medical staff can more targeted formulate subsequent medical intervention measures. For example, for high-risk patients, they can increase the monitoring frequency, adjust the dialysis plan in a timely manner, take preventive medications, etc., so as to more reasonably allocate medical resources, improve the efficiency and accuracy of medical work. It solves the problem of inaccurate assessment of the patient's infection risk.

[0086] The intelligent control module includes:

[0087] A dialysate parameter control sub-module, which is used to automatically send control instructions to the corresponding adjustment device in the dialysis equipment according to the abnormal situation of the dialysate parameters obtained from data analysis, and adjust the relevant parameters of the dialysate;

[0088] A dialysis process optimization sub-module, which is used to intelligently adjust and optimize the entire peritoneal dialysis process, including parameters such as dialysis frequency, duration, perfusion, and drainage speed, according to the risk assessment level of the patient developing peritoneal dialysis tunnel infection or peritonitis.

[0089] Specifically, the dialysate parameter control sub-module will receive the analysis result information of each parameter of the dialysate fed back by the dialysate status analysis sub-module. Once the analysis result shows that there are abnormal dialysate parameters, such as too high or too low dialysate temperature, pH deviation from the normal range, osmotic pressure not meeting the standard, etc.

[0090] The dialysis process optimization sub-module will obtain the risk assessment level result of the patient developing peritoneal dialysis tunnel infection or peritonitis given by the patient infection risk comprehensive assessment sub-module, such as low risk, medium risk, high risk level classification. Then, there are pre-set adjustment strategies for each parameter of the dialysis process corresponding to different risk levels inside the sub-module.

[0091] Through the automated and precise regulation of dialysate parameters, it is possible to respond immediately upon detecting abnormal dialysate parameters, send adjustment instructions to the dialysis equipment in a timely and accurate manner, and avoid potential delays and inaccuracies in manual intervention. By effectively adjusting the relevant parameters of the dialysate, it is ensured that the dialysate can always be in a suitable state that meets medical requirements, guarantee the normal progress of peritoneal dialysis treatment, and improve the dialysis effect. The problem of inaccurate regulation of dialysate parameters is solved.

[0092] The warning and feedback module includes:

[0093] A real-time warning sub-module, which is used to issue warning messages using sound, light, and a display screen when it is judged through data analysis that the patient has a high risk of infection;

[0094] A historical data feedback sub-module, which is used to record and store various types of data and risk assessment results collected in the past.

[0095] Specifically, the real-time warning sub-module continuously receives the assessment result data on the risk of peritoneal dialysis tunnel infection or peritonitis in the patient output by the comprehensive patient infection risk assessment sub-module. A determination threshold for the risk level is preset inside this sub-module to distinguish different degrees of infection risk situations. For example, when the assessment result shows that the patient's infection risk value exceeds the set high-risk threshold, it is determined that the patient is in a high infection risk state.

[0096] The historical data feedback sub-module establishes data connections with each data collection module (such as the dialysate parameter monitoring sub-module, the patient physiological data collection sub-module, etc.) and the risk assessment module (such as the comprehensive patient infection risk assessment sub-module, etc.). When these modules collect corresponding data or generate assessment results, they will transmit the data to the historical data feedback sub-module in real time. This sub-module is equipped with a large-capacity data storage device (such as a hard disk and other storage media), and stores various types of received data in an orderly manner according to specific data formats and classification rules. For example, it will record the temperature, pH value, and osmotic pressure data of each dialysate monitoring, the physiological data such as the patient's heart rate, blood pressure, and body temperature measured each time, and the patient infection risk assessment level results at different time points in chronological order.

[0097] Through the comprehensive, systematic, and long-term recording and storage of various types of past data related to peritoneal dialysis, a complete data archive is constructed, providing rich data resources for medical staff to review the patient's dialysis history and understand the trend of the disease. Through an intuitive presentation method, it is convenient for medical staff to perform data analysis, such as observing the change rules of the patient's various indicators over time and summarizing the dialysis treatment effects at different stages. The problem of poor management of peritoneal dialysis historical data and difficulty in effective utilization is solved.

[0098] The remote communication module includes:

[0099] A medical staff communication sub-module for real-time transmitting peritoneal dialysis-related data to the terminal devices of medical staff;

[0100] A patient education sub-module for pushing peritoneal dialysis-related knowledge, operation precautions, and tips on preventing infection to patients in various forms such as text, voice, and video.

[0101] Specifically, the medical staff communication sub-module first establishes a data connection channel with each module responsible for collecting and analyzing peritoneal dialysis-related data (such as a dialysis fluid parameter monitoring sub-module, a patient physiological data collection sub-module, a data analysis and risk assessment module, etc.), and can obtain the data information generated by these modules in real time, covering various aspects such as the temperature, pH value, and osmotic pressure of the dialysis fluid, the heart rate, blood pressure, body temperature of the patient, and the infection risk assessment level.

[0102] In the traditional peritoneal dialysis monitoring mode, medical staff mostly need to check the device data beside the patient or in a fixed monitoring room, which limits the activity range of medical staff, making it impossible to take into account more work tasks and efficiently manage multiple patients remotely. Moreover, once leaving the corresponding location, it is difficult to keep track of the latest situation of the patient in real time, and it is easy to have the problem of untimely response to the changes in the patient's condition.

[0103] Through the real-time and remote transmission of peritoneal dialysis-related data, medical staff can obtain the dialysis situation data of patients in a timely manner regardless of whether they are in different departments or offices in the hospital or in other places outside the hospital, as long as their terminal devices can access the corresponding network and open the receiving application program. This breaks the space limitation, greatly improves the monitoring efficiency of medical staff for patients, enables them to remotely monitor the conditions of multiple patients at the same time, and eliminates the need to always stay beside the patient to check the data. It solves the problem of the difficulty for medical staff to remotely obtain peritoneal dialysis data of patients in real time.

[0104] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
