Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an auxiliary system for hydration therapy. Background Art

[0002] Coronary angiography is a cardiac interventional diagnostic technique that uses contrast agents to visualize the coronary arteries of the heart, thereby helping doctors determine whether there are obstructive lesions in the coronary arteries, as well as the specific location and extent of the lesions. According to literature reports, about 20 to 30 million people in China need to use contrast agents during diagnosis and treatment each year, and the incidence of acute kidney injury after contrast imaging can be as high as 10% or more in general cardiology patients who undergo contrast agent examinations or interventional treatments, and even as high as 40% or more in ICU patients (Ozkok Sercin & Ozkok Abdullah. (2017). Contrast-induced acute kidney injury: A review of practical points. World journal of nephrology (3), 86-99). In addition, some high-risk patients, such as those with renal insufficiency, diabetes, gout, and long-term hypertension, have a certain risk of contrast-induced nephropathy.

[0003] Post-contrast Acute Kidney Injury (PC-AKI) is a common complication after coronary angiography. Hydration therapy is an important means to prevent and reduce contrast-induced acute kidney injury (CI-AKI) caused by the use of contrast agents during coronary angiography. Hydration therapy can increase renal blood flow (hydration therapy increases blood flow to the kidneys by increasing the body's water content, thereby providing more oxygen and nutrients to the kidneys and supporting normal kidney function), inhibit renal vasoconstriction (hydration helps prevent renal vasoconstriction caused by contrast agents, which may cause local ischemia in the kidneys), promote renal vasodilation (by increasing blood volume, hydration therapy helps dilate renal blood vessels and improves renal microcirculation), dilute contrast agents (hydration therapy can dilute contrast agents that enter the body, reduce their concentration in the kidneys, and reduce direct toxicity to the renal tubules), accelerate the excretion of contrast agents (by increasing urine volume, hydration therapy accelerates the excretion of contrast agents and reduces the burden on the kidneys), reduce renal tubular viscosity (hydration reduces urine viscosity and reduces the risk of crystallization and cast formation in the renal tubules), and reduce tubular cell toxicity (hydration therapy reduces the toxic effects of contrast agents on renal tubular cells and protects kidney function).

[0004] Currently, there is no uniform standard for hydration therapy for patients undergoing interventional treatment, but the following regimens are widely adopted: (1) Conventional oral hydration therapy: patients take an appropriate amount of water orally before receiving contrast agents to maintain their body hydration status; (2) Conventional fluid replacement hydration therapy: patients are provided with normal saline or other electrolyte solutions through intravenous rehydration to ensure adequate hydration; (3) Standard oral hydration therapy: patients take a specific amount of water according to a standardized regimen within a certain period of time before the use of contrast agents, such as taking 500 ml of water 2 hours before contrast imaging, and then taking 250 ml every 15 minutes until the start of contrast imaging.

[0005] The research results on oral hydration programs reported in domestic and foreign literature vary: there are large differences in the timing of intervention, the choice of oral fluids, and the control of fluid volume, and no unified program has been formed. In clinical practice, oral hydration is mostly based on previous clinical experience, without fixed standards and specifications (Tang Siyue. (2022). Construction of an evidence-based nursing practice program for oral hydration to prevent acute kidney injury after coronary angiography (Master's thesis, Fujian Medical University)).

[0006] CN215679087U discloses a weighing module circuit of a hydration therapy inlet and outlet balance system. This technical solution achieves hydration therapy only by maintaining the inlet and outlet balance, without considering the hydration timing or the physiological parameters used to feedback the patient's current condition.

[0007] Studies have shown that standard oral hydration therapy can improve the subjective comfort of patients undergoing interventional surgery, reduce the cost of hydration-related consumables and hydration-related time, and has no effect on the incidence of hydration-related complications and contrast-induced nephropathy. The defect of standard oral hydration therapy is the patient's compliance with drinking water. If the patient cannot strictly follow the doctor's orders for hydration therapy, it will still cause contrast-induced acute kidney injury. In addition, when conducting standard oral hydration therapy, the treatment plan is fixed and difficult to flexibly adjust according to actual conditions. It is not suitable for all patients, which in turn affects the patient's compliance with drinking water. That is, the current hydration therapy plan cannot work according to the specific circumstances of the individual. Therefore, the treatment effect is limited. In some cases, it will increase the risk of acute kidney injury after postoperative contrast imaging.

[0008] Mauro Maioli et al. explored the effect of fluid management strategy guided by bioimpedance vector analysis (BIVA) in preventing contrast-induced acute kidney injury (CI-AKI). Although the study evaluated the body fluid status through BIVA and adjusted the intravenous infusion volume accordingly, it did not disclose how to adjust the hydration strategy (such as water intake) according to the patient's own status (such as specific physiological parameters) during hydration therapy, and thus could not ensure the effectiveness of the treatment (Maioli, M., ToSo, A., Leoncini, M., Musilli, N., Grippo, G., Ronco, C., McCullough, PA, & Bellandi, F. (2018). Bioimpedance-Guided Hydration for the Prevention of Contrast-Induced Kidney Injury: The HYDRA Study. Journal of the American College of Cardiology, 71(25), 2880-2889).

[0009] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0010] Postoperative drinking guidance is crucial for patient recovery, especially when it comes to promoting the excretion of contrast agents after use and reducing the burden on the kidneys. At present, for the short-term drinking method, patients need to understand that the main purpose of drinking water after surgery is to accelerate the excretion of contrast agents and reduce the risk of kidney damage. The required drinking methods include: ① Within 3 hours after surgery: patients should drink 400 to 500 ml of water per hour as prescribed by the doctor. Drinking a lot of water at this stage helps to quickly increase urine output and promote the excretion of contrast agents. ② 3 hours to 24 hours after surgery: Within 21 hours after this, the patient's water intake should be appropriately reduced, and the total water intake throughout the day should not exceed 2000 ml. The purpose of this stage is to maintain a stable urine output while avoiding increasing the burden on the heart and kidneys due to excessive drinking. Due to the large difference in water intake within 24 hours after surgery, patients may find it difficult to accurately implement this guidance. Drinking more water than the recommended amount may increase the filtration burden on the kidneys, especially for patients with renal insufficiency, which may lead to edema or heart failure. If you don’t drink enough water, it may slow down the excretion of contrast media and increase the risk of kidney damage, especially in the postoperative period after contrast media administration. Inappropriate water intake may affect the patient’s overall recovery process, prolong hospital stay, and increase medical costs.

[0011] When nursing staff educate patients, they only remind them to "drink more water", but there is no specific, personalized hydration plan for the timing and amount of drinking water. In addition, the existing technology does not consider the impact of the external environment on the patient's willingness to drink water. Even if the patient is reminded, due to the inappropriate external environment or water temperature, the patient may not drink water according to the expected amount or timing of drinking water for hydration therapy.

[0012] In view of the shortcomings of the prior art, the present invention provides an auxiliary system for hydration therapy, comprising:

[0013] a container configured to store water to be consumed by the patient;

[0014] A collection unit disposed on the container, configured to collect information related to the water stored in the container;

[0015] A monitoring unit configured to obtain physiological parameter information reflecting the effect of hydration therapy on the patient, and a processing unit respectively connected to the acquisition unit and the monitoring unit signal,

[0016] The processing unit is configured to dynamically adjust the single water intake and / or water drinking interval in the patient's hydration plan according to the water volume change information stored in the container and the patient's urine volume and / or parameter information reflecting the blood volume status collected by the monitoring unit after the patient receives hydration therapy.

[0017] This system uses the acquisition unit to monitor the relevant information of the water in the container in real time, such as the change in water volume, to ensure that the patient takes in the prescribed amount of water according to the hydration plan, and avoids physical discomfort caused by drinking too much or too little water at one time. The monitoring unit obtains the patient's physiological parameters during the hydration treatment process, such as urine volume and parameters reflecting the blood volume status, to provide data support for the hydration effect, so as to dynamically adjust the hydration plan according to the patient's physical condition, abandoning the traditional fixed hydration plan. The processing unit comprehensively analyzes the patient's response to hydration therapy based on the collected water volume information and physiological parameters, and adjusts the single drinking water volume and drinking interval time to meet the patient's real-time needs, which helps to improve the efficiency and effectiveness of hydration therapy and reduce the risk of overhydration or dehydration.

[0018] In addition, the system can also reduce the medical risks caused by improper hydration, such as the situation where patients with heart failure may increase the burden on the heart due to excessive or rapid drinking of water. During the hydration treatment process, the system can provide a corresponding hydration plan according to the actual needs of the patient. For the physiological parameter feedback provided by the system in real time, the patient can grasp his or her own hydration status, and the patient can follow the treatment plan with more confidence. Therefore, the auxiliary system of the present invention can also improve the patient's compliance and ensure the smooth implementation of hydration treatment.

[0019] According to a preferred embodiment, the monitoring unit collects parameters reflecting the blood volume status including heart rate and blood pressure. Urine volume is a direct indicator for monitoring hydration status. If the urine volume decreases, it may indicate that the patient is at risk of dehydration; conversely, if the urine volume increases, it may indicate overhydration or normal renal function. Monitoring heart rate and blood pressure helps to evaluate the effect of hydration therapy. Proper hydration can maintain normal heart rate and blood pressure levels.

[0020] According to a preferred embodiment, the processing unit is configured to reduce the patient's single water intake when the difference between the patient's water intake and the single urine volume reflected by the water volume change information stored in the container exceeds a specified threshold and reflects fluid accumulation, and the heart rate is within a normal heart rate range, and the blood pressure is within a normal blood pressure range and reflects that the heart load is not affected.

[0021] When the difference between the amount of water a patient consumes and the amount of urine exceeds the specified threshold, it indicates that there is fluid accumulation (limited fluid excretion). Although the patient's current cardiac load is not affected, in order to avoid more serious consequences, especially for some patients with heart failure and kidney disease, if edema or other fluid overload occurs, the hydration plan needs to be adjusted in time. When fluid accumulation is detected, the amount of water drunk each time can be appropriately reduced. For example, if the patient usually drinks 250 ml of water at a time, you can consider reducing it to 150-200 ml. Since the patient's cardiac load is not affected, the interval between drinking water is not extended. While ensuring the safety of the patient's hydration treatment process, adjusting the hydration plan as little as possible will help improve patient compliance.

[0022] According to a preferred embodiment, the processing unit is configured to: reduce the patient's single water intake and extend the drinking interval time when the difference between the patient's water intake and single urine volume reflected by the water volume change information stored in the container is lower than a specified threshold, the heart rate exceeds the upper limit of the normal heart rate range, and the blood pressure exceeds the normal blood pressure range and reflects an increased heart load.

[0023] By continuously monitoring the patient's physiological indicators, the processing unit can capture the patient's blood volume status in real time. Since both the heart rate and blood pressure exceed the upper limit of the normal range, it means that hydration therapy has increased the patient's cardiac burden, so the amount of water consumed at a time is reduced and the interval between drinking water is extended. This setting effectively reduces the burden on the heart and reduces the risk of fluid retention. By reducing the amount of water consumed and extending the interval between drinking water, the system can effectively prevent related complications such as edema and dyspnea in the early stages.

[0024] According to a preferred embodiment, the processing unit is configured to shorten the drinking water interval when the difference between the patient's water intake and single urine volume reflected by the water volume change information stored in the container is lower than a specified threshold, the heart rate is within the normal heart rate range, but the blood pressure is lower than the lower limit of the normal blood pressure range, reflecting insufficient blood volume.

[0025] When a patient has fluid accumulation but insufficient blood volume, it is necessary to consider both the cardiac load and the timeliness of contrast agent discharge. This setting achieves more refined water management by dynamically adjusting the drinking interval. This flexibility ensures that the patient's fluid intake is within a safe range, avoiding fluid overload while meeting the body's need for water, effectively reducing the risk of complications caused by insufficient blood volume, such as syncope or dehydration, and improving the overall treatment effect.

[0026] According to a preferred embodiment, the processing unit is configured to reduce the patient's single water intake or extend the drinking interval when the difference between the patient's water intake and single urine volume reflected by the water volume change information stored in the container is lower than a specified threshold value and reflects fluid accumulation, and the heart rate is within a normal heart rate range, but the blood pressure exceeds the upper limit of the normal blood pressure range and reflects an increased heart load.

[0027] If the patient's heart rate is faster than the normal range, it may indicate dehydration. After excluding other causes (such as pain, anxiety), you can consider increasing the amount of hydration moderately. Low blood pressure may be a sign of dehydration, especially if the patient has low blood volume. At this time, the amount of hydration should be increased moderately, but be careful not to increase it too quickly to avoid causing a sharp increase in blood pressure. If hydration leads to an increase in blood volume, it may cause or aggravate hypertension. In this case, it may be necessary to reduce the amount of hydration and closely monitor changes in blood pressure. The amount of hydration can be controlled by reducing the amount of water the patient drinks at a single time or extending the interval between drinking water, thereby increasing the effect of hydration therapy while ensuring the safety of the body.

[0028] According to a preferred embodiment, the auxiliary system also includes a user interaction interface, which is used to input the patient's diet plan, and the processing unit is configured to: after receiving the input diet plan, calculate the invisible water intake according to the food type and consumption, and then adjust the single water drinking amount and / or drinking interval in the patient's hydration plan.

[0029] This setting can prevent the total water intake from exceeding the heart's tolerance. This solution is especially suitable for patients with heart failure. Excessive water intake will cause a sharp increase in blood volume, which will put an extra burden on the heart. The heart cannot pump blood effectively, which will cause pulmonary congestion or peripheral edema. For example, if the patient's daily diet includes fruits, vegetables, soups and other high-water foods (cucumbers, soup noodles, etc. contain high water content), the water intake can be reduced and / or the interval between drinking water can be extended.

[0030] According to a preferred embodiment, the processing unit is configured to automatically adjust the temperature of the water in the container according to the patient's physiological parameter information collected by the monitoring unit and / or the external ambient temperature and / or ambient humidity to control the patient's water intake speed and / or water drinking amount.

[0031] Preferably, a heating component and a refrigeration component are provided in the container to heat or cool the water in the container. This setting is particularly suitable for hospitalized patients, whose drinking water usually comes from the hospital's water room or bottled water in the supermarket, and it is difficult to accurately obtain the most suitable warm water for drinking. Especially in the case of taking boiled water in a container, the water temperature of the water stored in the container changes with the extension of the storage time, and the changed water temperature may not be suitable for patients to drink. For example, the intake of cold water may cause vasoconstriction. For patients with cardiovascular and cerebrovascular diseases, drinking cold water may induce angina pectoris or cerebral vasospasm. Patients with heart failure should not drink cold water or cold drinks, because overcooled drinks may increase heart rate and cardiac oxygen consumption, induce arrhythmia or angina pectoris. The temperature of boiled water is too high, not suitable for direct drinking, and may cause scalding. Due to the inappropriate water temperature, patients usually miss the set drinking time and reduce the amount of water they drink.

[0032] According to a preferred embodiment, the processing unit is configured to adjust the temperature of the water in the container according to historical physiological parameter information of the patient undergoing hydration therapy.

[0033] According to a preferred embodiment, the processing unit is configured to: when the historical physiological parameter information reflects that the patient's heart rate exceeds the normal heart rate range, or the blood pressure exceeds the normal blood pressure range each time after drinking water, control the heating component to heat the water in the container so that the water temperature in the container exceeds normal warm water.

[0034] For some special patients, such as those with heart failure, they cannot drink water too fast. The water temperature should be adjusted to a temperature higher than normal warm water. At this time, due to the high temperature, the patient will slow down the speed of drinking water, or reduce the amount of water consumed, thus controlling the extra burden on the heart. At the same time, drinking hot water in moderation can promote blood circulation and metabolism. Even if the amount of water consumed is reduced, the appropriate increase in water temperature can promote faster delivery of contrast agents to the kidneys and then excrete them from the body through urine. Hot water may also help improve the body's hemodynamics, thereby increasing the distribution of contrast agents in the body, making them more evenly present in the blood vessels, and helping them to be excreted through the kidneys.

[0035] According to a preferred embodiment, the processing unit can automatically generate a recommended amount of water to be drunk and an interval for drinking water according to the monitored external environmental factors, so as to ensure the effectiveness of the patient's water intake.

[0036] Preferably, the processing unit is configured to monitor external environmental factors, including temperature and humidity, in real time via environmental sensors, and integrate this information into the adjustment of the hydration regimen.

[0037] According to a preferred embodiment, a temperature sensor is provided in the container, which can monitor the temperature of the water in the container in real time and feed the information back to the processing unit for dynamic adjustment.

[0038] According to a preferred embodiment, the processing unit is configured to automatically adjust the temperature of the water according to the external ambient temperature and / or humidity, and control the heating component to heat the water in the container or control the cooling component to cool the water in the container before the next drinking time arrives, to ensure that the water is within a comfortable drinking range for the patient and to improve the patient's compliance.

[0039] For patients with personal preferences, when the weather is hot or the humidity is low, their body water loss is fast, especially in high temperature environment, body fluids are lost through sweat, so patients need to replenish water in time. If the water temperature is too high at this time, the patient will not want to drink water due to subjective reasons, resulting in insufficient drinking water. In this case, the processing unit controls the refrigeration component to cool the water in the container to meet the patient's personal preferences and body water balance. When the ambient temperature is cold, the processing unit controls the heating component to heat the water in the container to meet the patient's personal preferences. At the same time, when the external environment is cold, blood vessels tend to contract to reduce heat. Drinking hot water helps to dilate blood vessels, increase metabolic rate, and accelerate chemical reactions in the body (including the metabolism and excretion of contrast agents. Hot water may stimulate the kidneys to produce more urine), thereby improving patient compliance and ensuring the effect of hydration therapy.

[0040] Preferably, the heating component or cooling component of the container is configured to preheat or precool the water before the patient drinks it, so as to ensure that the patient enjoys the best water temperature experience when drinking the water.

[0041] According to a preferred embodiment, the processing unit is configured to generate a hydration therapy record of the patient and dynamically generate a subsequent hydration plan based on the patient's hydration history.

[0042] Past research results show that the incidence of urinary retention is 38.67% for patients who drink 500 ml of water within 1 hour, and 17.71% for patients who drink 1000 ml of water within 3 hours. For patients, these hydration plans based on past experience may cause discomfort to patients due to their low understanding ability or compliance. The present invention plans to design hydration plans according to individual conditions, and dynamically adjusts the hydration plans according to changes in the patient's physiological parameters during hydration treatment, so that the hydration plans can achieve better treatment effects.

[0043] Oral hydration according to the actual physical needs of the patient can promote the discharge process of the contrast agent, avoid the blockage of the renal tubules by contrast agent crystals after intervention, and can also reduce the concentration of contrast agent in the blood, thereby alleviating the toxic effects of contrast agent on the renal tubules. The present invention adjusts the patient's single water intake and / or water drinking interval in real time by detecting the patient's urine volume and / or changes in physiological parameters reflecting the blood volume state. The present invention can not only improve the patient's compliance, but also enhance the patient's cognition and self-management ability of their own hydration state through real-time feedback, and significantly reduce the medical risks caused by improper hydration, especially for some special patients, such as patients with heart failure.

[0044] The auxiliary system provided by the present invention can effectively reduce the incidence of PC-AKI and improve patient compliance and satisfaction. It will not increase the burden on the heart and stomach, and the incidence of adverse events such as stomach discomfort, intestinal discomfort, and urinary retention is low; it effectively promotes the excretion of contrast agents. The present invention can also adjust the patient's hydration therapy plan based on the patient's historical physiological parameter changes or external environmental factors. The present invention also takes into account applications in different environments and conditions, and can provide stable and reliable hydration therapy support whether in a hospital or home environment. The monitoring data provides strong technical support for medical practice and promotes the development of personalized medicine. BRIEF DESCRIPTION OF THE DRAWINGS

The collection unit 110 is preferably equipped with a temperature sensor 112 to obtain the water temperature in the container 100.

[0053] The monitoring unit 200 is configured to obtain physiological parameter information reflecting the effect of hydration therapy on the patient. Physiological parameter information includes parameters such as urine volume, heart rate, and blood pressure. The monitoring unit 200 preferably includes a smart wearable device 220, such as a smart bracelet or watch (HUAWEI or Apple Watch). The monitoring unit 200 also includes a urine volume monitoring module 210, such as a urine volume meter or a real-time urine volume monitor. The urine volume monitor uses ultrasonic technology for non-invasive measurement to provide continuous bladder capacity detection data.

[0054] The processing unit 300 is signal-connected to the collection unit 110 and the monitoring unit 200, respectively, to achieve data transmission. The collection unit 110 and the monitoring unit 200 include a wireless transmission module, which communicates with the processing unit 300 via wireless technologies such as Wi-Fi, Bluetooth or ZigBee. The collection unit 110 and the monitoring unit 200 preferably send the relevant information of the water in the container 100 and the collected physiological parameter information to the processing unit 300 in real time via a wireless network. Encryption technology is used in the data transmission process to ensure the security of patient information. According to a preferred embodiment, the processing unit 300 can be installed as an application (App) on mobile devices such as smartphones, tablets, computers, etc., and patients can interact with the system through an intuitive interface, such as Figure 3 As shown. The processing unit 300 uses a built-in algorithm to analyze data, evaluate the effect of hydration therapy, and intelligently recommend personalized hydration plans. The integrated App supports telemedicine services, allowing doctors to remotely access patient data through mobile devices and provide professional advice. The application on the mobile device can set notifications and reminders to ensure that patients drink water and take medicine on time. Preferably, the auxiliary system supports multi-user access, and patients, family members, and medical staff can view or manage data according to their own permissions. The processing unit 300 can provide health education materials such as videos, articles, and FAQs to help patients understand the importance and methods of hydration therapy. At the same time, patients can more intuitively understand their own hydration therapy status. This setting helps to improve patient compliance.

[0055] In the initialization stage T0, the processing unit 300 provides the smart wearable device 220 with reminders related to drinking water, so as to remind the user to drink a prescribed amount of water at prescribed time intervals.

[0056] In response to receiving the reminder related to drinking water, the collection unit 110 on the container 100 detects the user from the initial stage T0 to the initialization end T end The water volume change during the period, wherein, in response to each water volume change, the collection unit 110 on the container 100 provides information about the water volume change to the processing unit 300, and the processing unit 300 records the relevant information and the time point T associated with each water volume change received m .

[0057] In response to receiving the information of "the first water volume change from the initial stage T0", the processing unit 300 sends an instruction to the urine volume monitoring module 210 to detect the urine volume. After receiving the information of "the first water volume change from the initial stage T0", the urine volume monitoring module 210 will detect the urine volume of the user from the initial stage T0 to the end of initialization T0. end Total urine volume during the period s and single urine output U e .

[0058] From the initial stage T0 to the end of initialization T end During this period, the processing unit 300 also measures the parameter information reflecting the blood volume state in the initial stage, such as the heart rate HR, through the smart wearable device 220. pre (patient's heart beats per minute) and blood pressure BP pre (the patient's blood pressure, expressed as systolic pressure and diastolic pressure), or the processing unit 300 instructs the user to provide parameter information reflecting the blood volume state in the initial stage (HR pre , BP pre ).

[0059] In order to avoid acute kidney injury, after receiving the information of the first water volume change detected by the collection unit 110 in the container 100 in the initial stage T0, the processing unit 300 detects the water volume change information detected by the collection unit 110 in the container 100, the patient's urine volume detected by the urine volume monitoring module 210 and / or the patient's heart rate (HR) and blood pressure (BP) collected by the monitoring unit 200 during hydration therapy.

[0060] From the initial stage T0 to the end of initialization T endDuring this period, the processing unit 300 sends the first drinking water reminder to the user's smart wearable device 220 or user interaction interface, and the collection unit 110 on the container 100 detects the change in the amount of water the user drinks for the first time, and transmits the relevant information to the processing unit 300. In response to the receipt of the information on the first change in water volume, the processing unit 300 sends an instruction to the urine volume monitoring module 210 to detect the urine volume. The urine volume monitoring module 210 detects the user's initial urine volume. The processing unit 300 confirms that all necessary initial data have been recorded and meets the rationality verification criteria. The data collection tasks in the initialization phase (such as the initial water volume in the container 100, the first water volume change, the user's initial urine volume detection, the user's initial heart rate and initial blood pressure, etc.) are successfully completed. At the same time, the user is in the initial stage T0 to the end of initialization T end During this period, the heart rate and blood pressure remain stable without abnormal fluctuations, indicating that the user's body is in a stable state, which means that the initialization of the system is completed and the system will transition to the routine monitoring stage.

[0061] During the regular monitoring phase, the processing unit 300 sends a drinking reminder to the user's smart wearable device 220 or the user interface to remind the user to drink a specified amount of water at a specified time interval. The collection unit 110 on the container 100 detects the change in the amount of water the user drinks each time and transmits the relevant information to the processing unit 300. The processing unit 300 records the information of each water change and the relevant time point (T m In response to receiving the information of the first water volume change, the processing unit 300 sends an instruction to start detecting urine volume to the urine volume monitoring module 210. The urine volume monitoring module 210 detects the urine volume information of the user in the regular monitoring stage.

[0062] According to a preferred embodiment, the system of this embodiment further includes a bioimpedance monitoring unit to realize real-time monitoring of the bioimpedance value of the human body. The processing unit 300 is also configured to obtain the bioimpedance value of the human body collected by the bioimpedance monitoring unit. The bioimpedance monitoring unit can be, for example, a portable handheld device, an electronic weight scale with an integrated bioimpedance measurement function, or a dedicated medical device (such as EFG ElectroFluidGraph, etc.), which can be selected according to actual conditions.

[0063] The processing unit 300 of the auxiliary system for hydration therapy is configured as follows: after the patient receives hydration therapy, the processing unit 300 dynamically adjusts the single water drinking amount and / or water drinking interval in the patient's hydration plan according to the water volume change information provided by the collection unit 110 on the container 100 and the patient's urine volume and / or parameter information reflecting the blood volume status collected by the monitoring unit 200, wherein the parameters reflecting the blood volume status include, for example, heart rate, diastolic blood pressure and systolic blood pressure.

[0064] According to a preferred embodiment, the processing unit 300 combines multiple variables such as bioimpedance value, urine output, heart rate, diastolic blood pressure and systolic blood pressure to calculate a dynamic water intake adjustment value to dynamically adjust the single water intake and / or drinking interval in the patient's hydration plan. The water intake adjustment value is calculated based on the patient's physiological state and demand state to indicate the amount of water that the patient needs to consume at a specific time to ensure the normal operation of his fluid balance and physiological functions. The dynamic adjustment value ensures that the single water intake can reflect the patient's actual current water needs. The processing unit 300 is configured to calculate the water intake adjustment value, and the water intake adjustment formula is as follows:

[0065]

[0066] Where D is the current water intake adjustment value (ml); D t is the amount of water consumed corresponding to the target bioimpedance (ml); Z is the current bioimpedance value (Q); Z t is the target bioimpedance value (Q); U is the current urine output (ml); U max is the maximum urine output; HR is the current heart rate (beats / minute); HR target is the target heart rate (beats / min); DBP is the current diastolic blood pressure (mmHg); DBP target is the target diastolic blood pressure (mmHg); SBP is the current systolic blood pressure (mmHg); SBP target is the target systolic blood pressure (mmHg); α, β, γ, δ, ∈ are weight coefficients, reflecting the influence of each factor on the adjustment of water intake, and are values ​​between 0 and 1 respectively; D adjustment D is the adjustment coefficient of drinking water; t The amount of water consumed corresponding to the target bioimpedance is pre-set based on the patient's basic data and clinical condition.

[0067] According to the water intake adjustment formula of the present invention, the deviation of bioimpedance is calculated as follows:

[0076]

[0077] According to the water intake adjustment formula of the present invention, the effect of urine output is calculated as follows:

[0078]

[0079] The effect of urine output represents the ratio of the current urine output to the maximum possible urine output, and a negative value indicates that the amount of water intake needs to be reduced.

[0080] According to the present invention, the function of deviation calculation also considers more complex proportional relationships or nonlinear functions to better reflect the influence of physiological changes on water intake. Different weighting or nonlinear functions are used for different physiological parameters, and the weight coefficients α, β, γ, δ, ∈ are used to adjust the influence of various factors in adjusting water intake. The weight coefficients are set based on clinical experience or through regression analysis.

[0081] In the present invention, the basic path for setting weight coefficients α, β, γ, δ, ∈ is performed by the following steps, which combine clinical experience and statistical analysis. The content of determining these parameters in the present invention is described in detail below with reference to specific examples.

[0083] Feature standardization: Since different variables have different dimensions, the present invention standardizes the variables so that their mean is 0 and their standard deviation is 1. The standardization of the variables is as follows:

[0084]

[0085] Among them, μ is the mean of the variable and σ is the standard deviation.

[0086] Setting the initial weight coefficient: In the present invention, the initial weight coefficient is preliminarily set based on clinical experience or literature, for example:

[0092]

[0093] Among them, D predicted,i is the adjusted value of water intake calculated according to the formula, D actual,i Adjust the value to the actual amount of water you drink.

[0094] Regression Analysis:

[0095] In the present invention, a linear regression or other suitable regression method is used to establish a model, and the water intake adjustment value D is used as the dependent variable, and each physiological parameter (standardized value) is used as an independent variable to calculate the regression coefficient of each independent variable. The calculation formula of the water intake adjustment value D is as follows:

[0096] D=β0+β1Z+β2HR+β3DBP+β4SBP+β5U+∈

[0097] Among them, β1, β2, β3, β4, β5 are the regression coefficients of their respective variables.

[0098] Normalization of weight coefficients:

[0099] The regression coefficient is converted into a weight coefficient so that the sum thereof is 1. According to the present invention, the formula for converting the regression coefficient into the weight coefficient is as follows:

[0100]

[0101] Verification and adjustment:

[0102] The new weight coefficient is tested on the validation data set, the prediction error is calculated, and compared with the actual operation. When the error is unacceptable, the present invention further adjusts the weight coefficient through an optimization algorithm (such as grid search, random search, etc.). According to the present invention, the adjustment formula of the weight coefficient is as follows:

[0103] Findα,β,γ,δ,∈ to minimizeL(α,β,γ,δ,∈)

[0104] Implementation and Monitoring:

[0105] After the weight coefficient is determined, it is implemented in clinical practice. The present invention systematically sets and optimizes the weight coefficient in the water intake adjustment formula. After a period of implementation, the weight coefficient is re-evaluated and adjusted to ensure its applicability. In the present invention, the process of evaluating and adjusting the weight coefficient is based on a large amount of clinical experience or literature.

[0106] In the water intake adjustment formula, D adjustment is a constant, which is a dynamic value that changes according to the patient's physiological condition, such as changes in bioimpedance, fluctuations in heart rate, changes in diastolic and systolic blood pressure, and changes in urine volume. adjustment Used to adjust the final water intake adjustment value to adapt it to clinical needs. According to the present invention, this value can be adjusted under certain circumstances, such as based on clinical experience.

[0107] According to the present invention, the empirical data that need to be estimated are as follows:

[0108] Target bioimpedance value (Z t ): This value is determined based on the patient's basic data (such as gender, age, weight, height, etc.) and clinical experience. The patient's basic data is derived from, for example, reference to relevant literature or estimation using historical data.

[0109] Target water intake (D t ): The target water intake is set based on the patient's surgical type, preoperative status, fluid needs, and the physician's clinical judgment.

[0110] Target heart rate (HR target ): The target heart rate is set based on the patient's health status and clinical goals. The patient's health status is, for example, derived from preoperative heart monitoring data; the clinical goals are, for example, the normal heart rate range provided by reference medical literature and health guidelines.

[0111] Target diastolic blood pressure (DBP target ) and systolic blood pressure (SBP target ): It is set based on the patient's normal physiological range, medical history, and postoperative goals.

[0112] Weight coefficient (α, β, γ, δ, ∈): The weight coefficient reflects the influence of each factor on the adjustment of water intake. The weight coefficient is obtained through clinical experience, professional knowledge or data analysis.

[0113] Maximum urine output (U max ): This value is estimated based on the patient's historical urination data or the normal physiological range. The normal physiological range is obtained by referring to the data provided by medical literature and health guidelines.

[0114] In order to obtain the required estimated empirical data in the calculation formula of the water intake adjustment value, technicians in this field can search and refer to various channels or resource libraries. Through the following ways, technicians in this field can obtain and verify these empirical data to ensure that they can accurately apply these data in actual work. Specifically, the empirical data required in this embodiment is, for example, a medical record database from a hospital and a public medical record database after desensitization from relevant departments, in the form of, for example, electronic health record (EHR) data. In the present invention, the above parameters (water intake, urine output, bioimpedance, heart rate, blood pressure, etc.) can also be determined through clinical guidelines and standards and a large amount of reference data provided by standardization organizations and certification agencies; after obtaining the required empirical data, each deviation value is calculated and multiplied by the corresponding weight coefficient; all adjustment values ​​are added to obtain the final water intake adjustment value D.

[0115] Some functions or parameters in the formula can be adjusted under certain circumstances, for example, according to clinical experience, medical literature or professional guidelines. The system of this embodiment takes into account multiple physiological parameters and their interrelationships, which can provide dynamic adjustment suggestions for the water intake of perioperative patients. The system achieves more personalized fluid management through continuous monitoring and adjustment. According to the present invention, some functions or parameters in the formula can be adjusted under certain circumstances, for example, according to clinical experience, medical literature or professional guidelines. The system can also adjust weight coefficients and other parameters according to individual differences of patients. Information on individual differences of patients is obtained, for example, through methods such as clinical evaluation, laboratory tests, health monitoring equipment, and medical records.

[0116] The system of this embodiment further designs an optimization algorithm. Designing an optimization algorithm L to minimize the prediction error in the water intake adjustment formula is an important step. The present invention provides the following optimization algorithm example based on the gradient descent method.

[0117] 1. Define the objective function

[0118] According to the present invention, the objective function L is defined as follows:

[0119]

[0120] Among them, D predicted,i is the water intake adjustment value calculated using the current weight coefficient, D actual,i is the actual water intake adjustment value, and n is the sample size.

[0121] 2. Gradient calculation

[0122] In order to use the gradient descent method, the present invention calculates the partial derivative (gradient) of the objective function L with respect to each weight coefficient, and the calculation formula is as follows:

[0123]

[0124] In the present invention, the chain rule and the linear regression prediction formula are used to calculate the partial derivatives. Assume that D predicted,i It is given by the following formula:

[0125]

[0126] Here, the partial derivative is obtained by predicted,i It is obtained by taking the derivative of the weight coefficient.

[0127] 3. Gradient descent algorithm steps

[0128] The specific steps of the gradient algorithm provided by the present invention are as follows:

[0129] The process of initializing the weight coefficients is as follows:

[0130] α, β, γ, δ, ∈←0.2 (can be adjusted based on experience)

[0131] In the present invention, the process of initializing the weight coefficient is adjusted according to clinical experience, for example.

[0132] Set the learning rate:

[0133] Choose an appropriate learning rate η (such as 0.01), which determines the magnitude of each update step.

[0134] Loop until convergence:

[0135] Repeat the following steps until the preset number of iterations is reached or the change in the objective function is less than the threshold:

[0136] A. The formula for calculating the gradient is as follows:

[0137]

[0138] B. The formula for updating the weight coefficient is as follows:

[0139] α←α-η·g α

[0140] β←β-η·g β

[0141] γ←γ-η·g γ

[0142] δ←δ-η·g δ

[0143] ∈←∈-η·g ∈

[0144] C. Normalized weight coefficient:

[0145] To ensure that the sum of all weight coefficients is 1, the normalized weight coefficients are processed as follows:

[0146] Summm=α+β+γ+δ+∈

[0147]

[0148] Termination conditions:

[0149] If the change in the objective function L is less than the set threshold (such as 0.00 1), or the maximum number of iterations (such as 1000) is reached, the iteration is stopped.

[0150] 4. Implementation and evaluation

[0151] According to the present invention, after the iteration is completed, the new weight coefficient is evaluated on the validation data set to check the difference between the prediction accuracy and the actual water intake adjustment value.

[0152] This embodiment uses the above-mentioned optimization algorithm to continuously adjust the weight coefficient based on clinical data to minimize the prediction error and achieve personalization and precision of water intake.

[0153] Example 2

[0154] This embodiment is a further improvement of Embodiment 1, and repeated contents will not be repeated here.

[0155] Since the absorption and excretion of water by the human body is not instantaneous but a continuous process, it is necessary to accumulate all urine volumes between two drinking time points (for example, represented by T1 and T2 respectively) to accurately reflect the impact of each drinking time on urine volume. Preferably, in this embodiment, the single urine volume U refers to the cumulative amount of all urine volumes within the time interval between two adjacent drinking times.

[0156] Assume that the user drinks V1 and V2 amounts of water at time points T1 and T2, respectively, and that the user has multiple urination events between these two time points. Assume that the urination events occur at time points t1, t2, ..., t3, and the urine volumes of each urination are U1, U2, ..., U n .

[0157] The steps to calculate the change in urine volume caused by each water intake are as follows:

[0158] 1. Record the time and amount of drinking water:

[0159] Water intake at time T1 V1;

[0160] Water intake at time T2 is V2.

[0161] 2. Record urination events and urine volume between two drinking time points:

[0162] The urination time points between T1 and T2 are t1, t2, ... t3,

[0163] The corresponding urine output is U1, U2, ..., U n .

[0164] 3. Calculate total urine volume:

[0165] Add up all urine output between T1 and T2:

[0166]

[0167] 4. Calculate the change in urine volume caused by drinking water each time:

[0168] The change in urine volume corresponding to the amount of water consumed V1 is U total .

[0169] The change in urine volume after drinking water is not instantaneous, and there is a certain delay. Therefore, the urine volume between two adjacent time points needs to be accumulated to calculate the change in urine volume caused by each drinking of water. This is an important step to reflect the change in the user's hydration status and help ensure the effectiveness and accuracy of hydration therapy. By recording and analyzing detailed drinking and urination data, the system can better understand and manage the user's hydration status.

[0170] According to a preferred embodiment, the hydration therapy system provided in this embodiment has a manual input mode and an automatic monitoring mode, and the user can switch the mode of the system through the user interaction interface. The manual mode and the automatic monitoring mode are preferably applicable to both the initialization phase and the normal monitoring phase. In the manual input mode, the user can manually input the parameter information required by the system through the user interaction interface, such as heart rate, blood pressure, single water intake, single urine output, etc. The processing unit 300 receives the information uploaded by the user. The processing unit 300 performs a rationality check on the data input by the user to ensure that the data is within a reasonable range. When the data is unreasonable, the processing unit 300 prompts the user to re-enter or recommends switching to the automatic monitoring mode.

[0171] In the automatic monitoring mode, the acquisition unit 110 and the monitoring unit 200 automatically detect parameters and transmit them to the processing unit 300 .

[0172] In any mode, the user can choose to switch modes through the mobile application or user interface. The system will prompt the user to confirm the switching operation and explain the operating steps of the new mode in detail. Preferably, when switching modes, the processing unit 300 synchronizes the data of the current stage to the new mode to ensure data continuity and integrity. If data anomalies or device failures occur during the switching process, the processing unit 300 will prompt the user and suggest taking corresponding measures (such as restarting the device or contacting technical support).

[0173] During the routine monitoring phase, drinking water multiple times in a row may have a cumulative effect on the subsequent urine volume. When the single urine volume U caused by a later drinking time point (such as T3) is less than the single urine volume U at an earlier drinking time point (such as T2), the processing unit 300 identifies the abnormal urination trend and issues a prompt to the user through the smart wearable device 220 or the user interaction interface. Preferably, the prompt issued by the processing unit 300 can be to switch the current mode to verify whether the abnormal data is caused by the user's physical abnormality or a failure of the monitoring unit 200, thereby improving the accuracy of the analysis and ensuring the reliability and effectiveness of the system. According to a preferred embodiment, the processing unit 300 is configured to: after the patient receives hydration therapy, the single water intake and / or drinking interval in the patient's hydration plan are dynamically adjusted according to the water volume change information stored in the container 100 and the patient's urine volume and / or parameter information reflecting the blood volume status.

[0174] The processing unit 300 is configured to perform the following operations:

[0175] receiving the status of the patient after receiving hydration therapy; and determining the water volume change information V stored in the container 100 according to the water volume change information V C , as well as the patient's urine volume U (the patient's urine output) and / or parameter information B reflecting the blood volume status collected by the monitoring unit 200, so as to dynamically adjust the single water drinking volume D and / or the drinking interval T in the patient's hydration plan. The parameter information reflecting the blood volume status includes: heart rate HR (the patient's heart beats per minute) and blood pressure BP (the patient's blood pressure, expressed as systolic pressure and diastolic pressure).

[0176] Specifically, it can be expressed as: if (Vc, U, HR, BP) meets the conditions, D and T are dynamically adjusted.

[0177] The above technical solution can also be expressed as a data lookup table summarized through experience, as shown in Table 1.

[0178] Table 1

[0179]

[0180] According to a preferred embodiment, the monitoring unit 200 collects parameters reflecting the blood volume status including heart rate HR and blood pressure BP. Preferably, the physiological parameter information collected by the monitoring unit 200 can also include urine specific gravity. Urine specific gravity is an indicator of the concentration of solutes in urine and is related to the kidney's ability to reabsorb water; a lower urine specific gravity usually indicates a decrease in the kidney's reabsorption of water, which may be a sign of adequate hydration. If the urine specific gravity is high, it may mean that the kidneys reduce urine output in order to conserve water, which may be a sign of dehydration or insufficient fluid.

[0181] According to a preferred embodiment, the processing unit 300 is configured to: when the difference Δ (i.e. Δ=IU) between the patient's water intake I and the single urine volume U reflected by the water volume change information stored in the container 100 exceeds a specified threshold value T th Reflecting the accumulation of body fluid, the heart rate HR is in the normal heart rate range [HR min , HR max ], blood pressure BP is within the normal blood pressure range [BP min , BP max ]When the cardiac load is not affected, reduce the patient's single water intake by D.

[0182] The processing unit 300 is configured to perform the following operations:

[0183] If Δ>T th And (HR min ≤HR≤HR max ) and (BP min ≤BP≤BP max ), then D decreases.

[0184] According to a preferred embodiment, the processing unit 300 is configured to: when the difference Δ between the patient's water intake I and the single urine volume U reflected by the water volume change information stored in the container 100 is lower than the specified threshold value T th , heart rate HR exceeds the upper limit of the normal heart rate range HR max , blood pressure exceeds the normal blood pressure range [BP min , BP max ] When the heart load is increased, the patient's single water intake D is reduced and the interval between drinking water T is prolonged. Δ = IU.

[0185] The processing unit 300 is configured to perform the following operations:

[0186] If Δ <T th And (HR>HR max ) and (BP>BP max ), D decreases and T lengthens.

[0187] According to a preferred embodiment, the processing unit 300 is configured to: when the difference Δ between the patient's water intake I and the single urine volume U reflected by the water volume change information stored in the container 100 is lower than the specified threshold value T th , heart rate HR is in the normal heart rate range [HR min , HR max ], but the blood pressure BP is lower than the lower limit of the normal blood pressure range BP min When the blood volume is insufficient, the drinking interval T is shortened. Δ = IU.

[0188] The processing unit 300 is configured to perform the following operations:

[0189] If Δ <T th And (HR min ≤HR≤HR max ) and (BP <BP min ), then T is shortened.

[0190] According to a preferred embodiment, the processing unit 300 is configured to: when the difference Δ between the patient's water intake I and the single urine volume U reflected by the water volume change information stored in the container 100 is lower than the specified threshold value T th , heart rate is within the normal heart rate range [HR min , HR max ], but blood pressure exceeds the upper limit of the normal blood pressure range BP max When the heart load is increased, the patient's single water intake D is reduced or the interval between drinking water T is extended. Δ = IU.

[0191] The processing unit 300 is configured to perform the following operations:

[0192] If Δ <T th And (HR min ≤HR≤HR max ) and (BP>BP max ), then D decreases or T increases.

[0193] Normal heart rate but falling blood pressure: This may be a sign of hypovolemia and the patient needs to be evaluated for more fluids, especially if they are taking diuretics. Normal heart rate but elevated blood pressure: If blood pressure rises and heart rate remains the same, you may need to consider reducing the amount of hydration or extending the interval between fluids, especially if the patient has a history of heart disease or hypertension.

[0194] According to a preferred embodiment, the auxiliary system also includes a user interaction interface 400, which is used to input the patient's diet plan. The processing unit 300 is configured to: after receiving the input diet plan, calculate the invisible water intake according to the food type and consumption, and then adjust the single water drinking amount and / or drinking interval in the patient's hydration plan.

[0195] This setting can prevent the total water intake from exceeding the heart's tolerance. This solution is particularly suitable for patients with heart failure. Excessive water intake will cause a sharp increase in blood volume, which will put an extra burden on the heart. The heart cannot effectively pump blood, which will cause pulmonary congestion or peripheral edema. For example, the patient's daily diet includes fruits, vegetables, soups and other high-water foods (cucumbers, soup noodles, etc. contain high water content). When the processing unit 300 analyzes that the patient drank more soup and ate more vegetables with high water content at lunch, the patient's next water drinking time will be delayed, and the next water drinking amount will be reduced.

[0196] According to a preferred embodiment, the processing unit 300 is configured to automatically adjust the temperature of the water in the container 100 according to the patient's physiological parameter information and / or the external ambient temperature and / or ambient humidity collected by the monitoring unit 200 to control the patient's water intake speed and / or water drinking amount.

[0197] Preferably, a heating component 113 and a cooling component 114 are provided in the container 100 to heat or cool the water in the container 100. Figure 2 shown.

[0198] According to a preferred embodiment, the processing unit 300 is configured to adjust the temperature of the water in the container 100 according to historical physiological parameter information of the patient undergoing hydration therapy.

[0199] According to a preferred embodiment, the processing unit 300 is configured to: when the historical physiological parameter information reflects that the patient's heart rate HR exceeds the normal heart rate range [HR min , HR max ], or blood pressure exceeds the normal blood pressure range [BP min , BP max ], the heating component 113 is controlled to heat the water in the container 100 so that the water temperature in the container 100 is T w Exceeding normal warm water T normal .

[0200] The processing unit 300 is configured to perform the following operations:

[0201] If (HR>HR max ) or (BP>BP max or BP <BP min ), then T w >T normal .

[0202] For example, for patient A, each time he drinks water, his heart rate rises and exceeds the normal range, and his urine volume decreases. The processing unit 300 controls the heating component 113 to heat the water in the container 100 according to the historical physiological data, such as heating from 30°C to 50°C. Due to the high water temperature, the patient's drinking speed and drinking amount are indirectly controlled (the patient would like to wait for the water to cool down before drinking).

[0203] According to a preferred embodiment, the processing unit 300 can automatically generate a recommended amount of water to be drunk and an interval for drinking water according to the monitored external environmental factors, so as to ensure the effectiveness of the patient's water intake.

[0204] Preferably, the processing unit 300 is configured to monitor external environmental factors, including temperature and humidity, in real time through environmental sensors, and integrate this information into the adjustment of the hydration regimen.

[0205] According to a preferred embodiment, a temperature sensor 112 is provided in the container 100, which can monitor the temperature of the water in the container 100 in real time and feed the information back to the processing unit 300 for dynamic adjustment.

[0206] According to a preferred embodiment, the processing unit 300 is configured to automatically adjust the temperature of the water according to the external ambient temperature and / or humidity, and control the heating component 113 to heat the water in the container 100 or control the cooling component 114 to cool the water in the container 100 before the next drinking time arrives, to ensure that the water is within a comfortable drinking range for the patient and to improve the patient's compliance.

[0207] Preferably, the heating component 113 or the cooling component of the container 100 is configured to preheat or precool the water before the patient drinks the water, so as to ensure that the patient enjoys the best water temperature experience when drinking the water.

[0208] According to a preferred embodiment, the processing unit 300 is configured to generate a hydration therapy record of the patient and dynamically generate a subsequent hydration plan based on the patient's hydration history.
