Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary equipment, in particular to an auxiliary system for hydration therapy. BACKGROUND

[0002] Coronary angiography is a heart interventional diagnostic technique, which makes the coronary artery of the heart develop by using contrast agent, so as to help doctors judge whether there is obstructive lesion in the coronary artery, and the specific position and degree of the lesion. According to the literature, about 2000-3000 million people need to use contrast agent in the diagnosis and treatment process in China every year, and among the general cardiology patients receiving contrast examination or interventional treatment, the incidence of acute kidney injury after contrast can be as high as more than 10%, and the incidence of acute kidney injury after contrast in ICU patients can even be as high as more than 40% (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 renal dysfunction, diabetes, gout, long-term hypertension, etc., have certain contrast-induced nephropathy risk.

[0003] Post-contrast Acute Kidney Injury (PC-AKI) is a relatively common complication after coronary angiography. Hydration therapy is an important means to prevent and reduce acute kidney injury (CI-AKI) caused by the use of contrast agent in coronary angiography. Hydration therapy can increase renal blood flow (hydration therapy increases the water content in the body, increases the blood flow of the kidney, thereby providing more oxygen and nutrients for the kidney to support normal kidney function), inhibit renal vasoconstriction (hydration helps prevent renal vasoconstriction caused by contrast agents, which can cause local ischemia in the kidney), promote renal vasodilation (by increasing blood volume, hydration therapy helps to dilate the renal blood vessels and improve the microcirculation of the kidney), dilute the contrast agent (hydration therapy can dilute the contrast agent entering the body, reduce its concentration in the kidney, and reduce the direct toxicity to the renal tubule), accelerate the excretion of contrast agent (by increasing urine output, hydration therapy accelerates the excretion of contrast agent and reduces the burden on the kidney), reduce the viscosity of the renal tubule (hydration reduces the viscosity of urine, reducing the risk of crystallization and cast formation in the renal tubule), and reduce renal 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 schemes are widely adopted: (1) routine oral hydration therapy: patients take in an appropriate amount of water before receiving contrast agents to maintain the body's hydration status; (2) routine fluid replacement hydration therapy: through intravenous fluid replacement, physiological saline or other electrolyte solutions are provided to ensure adequate hydration; (3) standard oral hydration therapy: within a certain time before the use of contrast agents, patients take in a specific amount of water according to a standardized scheme, such as 500 ml of water 2 hours before the contrast, and then 250 ml every 15 minutes until the contrast begins.

[0005] The results of research on oral hydration schemes reported in domestic and foreign literature are different: there are great differences in the timing of intervention, the choice of oral liquid, and the control of liquid volume, and no uniform scheme has been formed. In clinical practice, oral hydration is often implemented based on previous clinical experience without fixed standards and norms (Tang Siming. (2022). Construction of evidence-based nursing practice scheme for preventing acute kidney injury after coronary angiography (Master's thesis, Fujian Medical University)).

[0006] CN215679087U discloses a hydration therapy in-out liquid balance system weighing module circuit, which only maintains in-out liquid balance to achieve hydration therapy, without considering the timing of hydration and physiological parameters for feeding back the current situation of the patient.

[0007] Studies have shown that standard oral hydration therapy can improve the subjective comfort of patients undergoing interventional surgery, reduce hydration-related consumable costs and hydration-related time, while having no effect on the incidence of hydration-related complications and the incidence of contrast-induced nephropathy. The defect of standard oral hydration therapy is the patient's drinking water compliance. If the patient cannot strictly follow the doctor's advice for hydration therapy, it will still cause contrast-induced acute kidney injury. In addition, the current standard oral hydration therapy has a fixed treatment scheme, which is difficult to adjust flexibly according to the actual situation, and is not suitable for all patients, which further affects the patient's drinking water compliance. That is, the current hydration therapy scheme cannot play a role according to the specific situation of the individual, so the treatment effect is limited, and in some cases, it may even increase the risk of postoperative contrast-induced acute kidney injury.

[0008] Mauro Maioli et al. explored the effect of fluid management strategies guided by bioimpedance vector analysis (BIVA) in the prevention of contrast-induced acute kidney injury (CI-AKI), although the study assessed the body fluid status through BIVA and adjusted the intravenous fluid volume accordingly, it did not disclose how to adjust the hydration strategy (such as the amount of drinking water) according to the changes in the patient's own state (such as specific physiological parameters) during the hydration treatment, thus it cannot ensure the effectiveness of the treatment (Maioli, M., Tosso, A., Leoncini, M., Musilli, N., Grippo, G., Ronco, C., McCullough, P. A., & 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, due to the difference in understanding of those skilled in the art; on the other hand, due to the limited space, the applicant did not list all the details and contents when he studied a large number of literatures and patents when he made the invention, but this does not mean that the invention does not have the characteristics of the prior art. On the contrary, the invention has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. SUMMARY

[0010] Postoperative water drinking guidance is essential for patient recovery, especially when it comes to facilitating the excretion of contrast agents after their use and reducing the burden on the kidneys. Current methods for short-term water drinking require patients to understand that the main purpose of postoperative water drinking is to accelerate the excretion of contrast agents and reduce the risk of kidney damage. The required water drinking method includes: ① Within 3 hours after surgery: the patient should drink 400 to 500 milliliters of water per hour as prescribed. The large amount of water in this stage helps to quickly increase urine output and promote the excretion of contrast agents. ② 3 hours to 24 hours after surgery: within the next 21 hours, the patient's water intake should be appropriately reduced, and the total daily water intake should not exceed 2000 milliliters. The purpose of this stage is to maintain stable urine output while avoiding excessive water intake that increases the burden on the heart and kidneys. 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 recommended can increase the filtration burden on the kidneys, especially for patients with kidney dysfunction, which can lead to edema or heart failure. If the water intake is insufficient, it may slow down the excretion of contrast agents and increase the risk of kidney damage, especially during the postoperative period after the use of contrast agents. Inappropriate water intake can affect the overall recovery process of the patient, prolong hospitalization time, and increase medical costs.

[0011] When nurses provide health education, they only remind patients to "drink more water", but there is no specific and personalized hydration plan for the timing and amount of water drinking. In addition, the prior art does not consider the influence of the external environment on the patient's willingness to drink water. Even if the patient is reminded, the patient may not hydrate according to the expected amount of water or the timing of water drinking due to an unsuitable external environment or water temperature.

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

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

[0014] a collection unit provided on the container and configured to collect information about the water stored in the container;

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

[0016] the processing unit is configured to dynamically adjust the single water drinking amount and / or the water drinking interval time in the hydration plan of the patient according to the water volume change information of the water stored in the container and the urine output and / or parameter information reflecting the blood volume state of the patient collected by the monitoring unit after the patient receives the hydration therapy.

[0017] This system uses a data acquisition unit to monitor water-related information in the container in real time, such as water volume changes, to ensure that patients consume the prescribed amount of water according to the hydration protocol, avoiding discomfort caused by drinking too much or too little water at once. The monitoring unit acquires physiological parameters during the patient's hydration treatment, such as urine output and parameters reflecting blood volume status, to provide data support for the hydration effect. This allows for dynamic adjustment of the hydration protocol based on the patient's physical condition, abandoning the traditional fixed hydration protocol. The processing unit comprehensively analyzes the patient's response to hydration treatment based on the collected water volume information and physiological parameters. By adjusting the single water intake and drinking intervals to adapt to the patient's real-time needs, it helps improve the efficiency and effectiveness of hydration treatment and reduces the risk of over-hydration or dehydration.

[0018] Furthermore, this system can reduce medical risks caused by improper hydration, such as increased cardiac burden in patients with heart failure due to excessive or rapid water intake. During hydration therapy, the system can provide corresponding hydration plans based on the patient's actual needs. The real-time physiological parameter feedback from the system allows patients to monitor their hydration status and follow the treatment plan with greater confidence. Therefore, the auxiliary system of this invention can also improve patient compliance and ensure the smooth execution of hydration therapy.

[0019] According to a preferred embodiment, the monitoring unit collects parameters reflecting blood volume status, including heart rate and blood pressure. Urine output is a direct indicator of hydration status; decreased urine output may indicate a risk of dehydration, while increased urine output may indicate overhydration or normal renal function. Monitoring heart rate and blood pressure helps assess the effectiveness 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 single urine volume, as reflected by the water volume change information stored in the container, exceeds a predetermined threshold, indicating fluid accumulation; the heart rate is within the normal heart rate range; and the blood pressure is within the normal blood pressure range, indicating that the cardiac load has not been affected.

[0021] When the difference between a patient's fluid intake and urine output exceeds a prescribed threshold, it indicates fluid retention (restricted fluid excretion). Although the patient's current cardiac workload is not affected, to avoid more serious consequences, especially in patients with heart failure or kidney disease, if edema or other fluid overload occurs, the hydration regimen needs to be adjusted promptly. When fluid retention is detected, the amount of water consumed at each feeding can be appropriately reduced. For example, if a patient usually drinks 250 ml of water at a time, it can be reduced to 150-200 ml. Since the patient's cardiac workload is not affected, the interval between drinking sessions should not be extended. Minimizing adjustments to the hydration regimen while ensuring the patient's safety during hydration therapy helps 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 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 predetermined threshold, the heart rate exceeds the upper limit of the normal heart rate range, and the blood pressure exceeds the normal blood pressure range, reflecting increased cardiac 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 heart rate and blood pressure exceeded the upper limit of the normal range, it indicated that hydration therapy was increasing the burden on the patient's heart. Therefore, the amount of water consumed at each feeding was reduced, and the interval between feedings was extended. This setting effectively reduced the burden on the heart and decreased the risk of fluid retention. By reducing the amount of water consumed and extending the intervals between feedings, 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 interval when the difference between the patient's water intake and single urine volume, as reflected by the water volume change information stored in the container, is lower than a predetermined 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 experiences fluid retention but also hypovolemia, both cardiac load and the time required for contrast agent removal need to be considered. This setting allows for more precise fluid management by dynamically adjusting the drinking interval. This flexibility ensures that the patient's fluid intake remains within a safe range, avoiding fluid overload while meeting the body's hydration needs. This effectively reduces the risk of complications caused by hypovolemia, such as syncope or dehydration, and improves overall treatment outcomes.

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

[0027] If a patient's heart rate is faster than normal, it may indicate dehydration. After ruling out other causes (such as pain or anxiety), a moderate increase in hydration may be considered. Low blood pressure can also be a sign of dehydration, especially in patients with low blood volume. In this case, hydration should be increased moderately, but care should be taken not to increase it too quickly to avoid a sharp rise in blood pressure. If hydration leads to an increase in blood volume, it may cause or worsen hypertension. In this case, it may be necessary to reduce hydration and closely monitor blood pressure changes. The effectiveness of hydration therapy can be increased while ensuring the patient's safety by controlling the amount of water the patient drinks at each feeding or by extending the intervals between drinking sessions.

[0028] According to a preferred embodiment, the auxiliary system further includes a user interface for inputting the patient's diet plan. The processing unit is configured to: after receiving the input diet plan, calculate the implicit water intake based on the food type and amount consumed, and then adjust the single water intake and / or water intake interval in the patient's hydration plan.

[0029] This setup prevents total fluid intake from exceeding the heart's capacity. It is particularly suitable for patients with heart failure, as excessive fluid intake can lead to a rapid increase in blood volume, placing an extra burden on the heart. This can prevent the heart from pumping blood effectively, resulting in pulmonary congestion or peripheral edema. For example, if a patient's daily diet includes fruits, vegetables, soups, and other high-water-content foods (such as cucumbers and noodle soup), fluid intake can be reduced and / or the intervals between drinks 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 based on the patient's physiological parameter information collected by the monitoring unit and / or the external ambient temperature and / or ambient humidity, so as to control the patient's water intake rate and / or water consumption.

[0031] Preferably, the container is equipped with heating and cooling components to heat or cool the water inside. This setup is particularly suitable for hospitalized patients, whose drinking water typically comes from hospital water dispensers or bottled water from supermarkets, making it difficult to accurately obtain the most suitable drinking temperature. Especially when drawing boiling water from the container, the water temperature changes constantly over time, and the resulting temperature may not be suitable for the patient. For example, drinking cold water may cause vasoconstriction, and for patients with cardiovascular and cerebrovascular diseases, drinking cold water may induce angina or cerebral vasospasm. Patients with heart failure should not drink cold water or cold drinks, as excessively cold beverages may increase heart rate and myocardial oxygen consumption, inducing arrhythmia or angina. Boiled water, on the other hand, is too hot to drink directly and may cause burns. Due to unsuitable water temperature, patients often miss their designated drinking times and reduce their water intake.

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

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

[0034] For some patients, such as those with heart failure, drinking water should not be too fast. The water temperature should be adjusted to above normal lukewarm. At this temperature, the patient will slow down their drinking rate or reduce the amount of water they drink, thus controlling the extra burden on the heart. At the same time, drinking a moderate amount of hot water can promote blood circulation and metabolism. Even with reduced water intake, the appropriately higher water temperature can facilitate the faster delivery of contrast agents to the kidneys, where they are then excreted through urine. Hot water may also help improve hemodynamics, thereby increasing the distribution of contrast agents in the body, making them more evenly distributed in the blood vessels and facilitating their excretion through the kidneys.

[0035] According to a preferred embodiment, the processing unit can automatically generate recommended water intake and drinking intervals based on monitored external environmental factors 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 scheme.

[0037] According to a preferred embodiment, a temperature sensor is provided inside 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 water temperature according to the external ambient temperature and / or humidity, control the heating element to heat the water in the container or control the cooling element 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 improve patient compliance.

[0039] For patients with personal preferences, their bodies lose water quickly in hot or low-humidity weather, especially in high-temperature environments where fluids are lost through sweat, requiring timely hydration. If the water temperature is too high, patients may not want to drink due to subjective reasons, resulting in insufficient water intake. In this case, the processing unit controls the cooling component to cool the water in the container to meet the patient's personal preference and maintain body hydration 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 preference. Simultaneously, in cold environments, blood vessels tend to constrict to reduce heat; drinking hot water helps dilate blood vessels, increases metabolic rate, and accelerates internal chemical reactions (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 effectiveness of hydration therapy.

[0040] Preferably, the heating or cooling components of the container are 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.

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

[0042] Previous studies have shown that the incidence of urinary retention is 38.67% when patients drink 500ml of water within 1 hour and 17.71% when they drink 1000ml of water within 3 hours. For patients, due to their limited understanding or poor adherence, these hydration protocols based on past experience may actually cause discomfort. This invention designs hydration protocols in a planned manner tailored to individual circumstances, and dynamically adjusts the protocol based on changes in the patient's physiological parameters during hydration therapy to achieve better therapeutic effects.

[0043] Oral hydration, tailored to the patient's actual needs, can promote the excretion of contrast agents, preventing contrast agent crystallization and renal tubule blockage after interventional procedures. It can also reduce the concentration of contrast agents in the blood, thereby mitigating the toxic effects of contrast agents on the renal tubules. This invention adjusts the patient's single water intake and / or drinking interval in real time by detecting changes in urine output and / or physiological parameters reflecting blood volume status. This improves patient compliance, enhances patient awareness and self-management of their hydration status through real-time feedback, and significantly reduces medical risks caused by improper hydration, especially for certain patients such as those with heart failure.

[0044] The auxiliary system provided by this invention can effectively reduce the incidence of PC-AKI and improve patient compliance and satisfaction. It does not increase the burden on the heart or stomach, and has a low incidence of adverse events such as gastrointestinal discomfort, intestinal discomfort, and urinary retention; it also effectively promotes contrast agent excretion. This invention can also adjust the patient's hydration therapy plan based on changes in the patient's historical physiological parameters or external environmental factors. This invention also considers application under different environments and conditions, providing stable and reliable hydration therapy support in both hospital and home settings. Monitoring data provides strong technical support for medical practice and promotes the development of personalized medicine. Attached Figure Description

[0050] The following is a detailed explanation with reference to the accompanying drawings.

[0051] Example 1

[0052] This embodiment provides an auxiliary system for hydration therapy, such as... Figure 1The system includes: a container 100, a data acquisition unit 110 disposed on the container 100, a monitoring unit 200, and a processing unit 300. The container 100 is used to store water for a patient to drink. The container 100 is preferably equipped with graduations to accurately measure the patient's water intake. Preferably, the data acquisition unit 110 is disposed within the container 100 to acquire information related to the stored water. This information includes water volume, water volume changes, and water temperature. The data acquisition unit 110 is preferably equipped with a high-precision water volume sensor 111. The water volume sensor 111 is used to acquire changes in the water volume in the container 100. The data acquisition unit 110 is preferably equipped with a temperature sensor 112 to acquire the water temperature in the container 100.

[0053] The monitoring unit 200 is configured to acquire physiological parameters reflecting the effectiveness of hydration therapy in patients. These physiological parameters include urine output, 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 output monitoring module 210, such as a urinalysis or real-time urine output monitor. The urinalysis monitor utilizes ultrasound technology for non-invasive measurement to provide continuous bladder capacity data.

[0054] The processing unit 300 is signal-connected to both the acquisition unit 110 and the monitoring unit 200 to enable data transmission. The acquisition unit 110 and the monitoring unit 200 include wireless transmission modules that communicate with the processing unit 300 via wireless technologies such as Wi-Fi, Bluetooth, or ZigBee. Preferably, the acquisition unit 110 and the monitoring unit 200 transmit information related to the water in the container 100 and the collected physiological parameters to the processing unit 300 in real time via a wireless network. Encryption technology is used throughout the data transmission process to ensure patient information security. According to a preferred embodiment, the processing unit 300 can be installed as an application (App) on mobile devices such as smartphones, tablets, and computers, allowing patients to interact with the system through an intuitive interface, such as… Figure 3 As shown. The processing unit 300 uses built-in algorithms to analyze data, evaluate the effectiveness of hydration therapy, and intelligently recommend personalized hydration plans. The integrated app supports telemedicine services, allowing doctors to remotely access patient data via mobile devices and provide professional advice. The app on the mobile device can be set to send notifications and reminders to ensure patients drink water and take medication on time. Preferably, the auxiliary system supports multi-user access, allowing patients, family members, and healthcare personnel to view or manage data according to their 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. Simultaneously, patients can more intuitively understand their own hydration therapy status, which helps improve patient adherence.

[0055] During the initialization phase T0, the processing unit 300 provides drinking-related prompts to the smart wearable device 220 to remind the user to drink the prescribed amount of water at specified time intervals.

[0056] In response to receiving a prompt related to drinking water, the acquisition unit 110 on container 100 detects the user from the start of the initial phase T0 to the end of the initialization T. end During the period, water volume changes, wherein, in response to each water volume change, the acquisition unit 110 on container 100 provides information about the water volume change to the processing unit 300, and the processing unit 300 records the relevant information and receives the time point T associated with each water volume change. m .

[0057] In response to receiving the information "First water volume change starting from initial stage T0", processing unit 300 sends a command to urine volume monitoring module 210 to detect urine volume. After receiving the information "First water volume change starting from initial stage T0", urine volume monitoring module 210 will detect the user's urine volume from initial stage T0 to the end of initialization T. end Total urine volume during the period U s and single urine volume U e .

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

[0059] To avoid acute kidney injury, after receiving the information on the first water volume change detected by the acquisition unit 110 in the container 100 at the initial stage T0, the processing unit 300, based on the water volume change information detected by the acquisition unit 110 in the container 100, the urine volume of the patient detected by the urine volume monitoring module 210, and / or the heart rate (HR) and blood pressure (BP) of the patient collected by the monitoring unit 200 during the hydration treatment.

[0060] From the initial phase T0 to the end of initialization T endDuring this period, the processing unit 300 sends a first drinking prompt to the user's smart wearable device 220 or user interface. The acquisition unit 110 on the container 100 detects the change in the amount of water the user drinks during this first drinking and transmits the relevant information to the processing unit 300. In response to the receipt of the first water volume change information, the processing unit 300 sends a command to the urine volume monitoring module 210 to detect 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 has been recorded and meets the rationality verification standards. The data acquisition tasks of 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) are successfully completed. Simultaneously, the user's initial phase T0 to the end of initialization T... end During this period, the heart rate and blood pressure remained stable without any abnormal fluctuations, indicating that the user's body was in a stable state. This means that the initialization of the system is complete and the system will transition to the routine monitoring phase.

[0061] During the routine monitoring phase, the processing unit 300 sends a drinking reminder to the user's smart wearable device 220 or user interface to remind the user to drink the prescribed amount of water at specified time intervals. The data acquisition unit 110 on the container 100 detects changes in water volume each time the user drinks and transmits the relevant information to the processing unit 300. The processing unit 300 records information about each water volume change and the relevant time point (T). m Upon receiving information about the first change in water volume, the processing unit 300 sends a command to the urine volume monitoring module 210 to start detecting urine output. The urine volume monitoring module 210 detects the user's urine output information during the routine monitoring phase.

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

[0063] The processing unit 300 of the auxiliary system for hydration therapy is configured to: when a patient receives hydration therapy, the processing unit 300 dynamically adjusts the single water intake and / or water intake interval in the patient's hydration protocol based on the water volume change information provided by the acquisition unit 110 on the container 100 and the patient's urine volume and / or parameter information reflecting blood volume status collected by the monitoring unit 200, wherein the parameters reflecting 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 fluid intake adjustment value, thereby dynamically adjusting the single fluid intake and / or drinking interval in the patient's hydration protocol. This fluid intake adjustment value, calculated based on the patient's physiological state and needs, represents the amount of water the patient needs to ingest at a specific time to ensure fluid balance and normal physiological function. This dynamic adjustment value ensures that the single fluid intake reflects the patient's current actual fluid requirements. The processing unit 300 is configured to calculate the fluid intake adjustment value, and the fluid intake adjustment formula is as follows:

[0065]

[0066] Where D is the current water intake adjustment value (ml); D t Z represents the water intake (ml) corresponding to the target bioimpedance; Z represents the current bioimpedance value (Q); Z t Target bioimpedance value (Q); U is the current urine output (ml); U max Maximum urine output; HR is current heart rate (beats / min); HR target Target heart rate (beats / min); DBP is current diastolic blood pressure (mmHg); DBP target Target diastolic blood pressure (mmHg); SBP is current systolic blood pressure (mmHg); SBP target Target systolic blood pressure (mmHg); α, β, γ, δ, ∈ are weighting coefficients reflecting the influence of each factor on water intake adjustment, and are values ​​between 0 and 1; D adjustment D is the adjustment factor for water intake; t The target bioimpedance corresponds to the amount of water consumed, a value that is preset based on the patient's baseline data and clinical condition.

[0067] According to the drinking water 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 impact of urine output represents the ratio of the current urine output to the maximum possible urine output; a negative value indicates that the amount of water intake needs to be reduced.

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

[0081] In this invention, the basic approach for setting the weighting coefficients α, β, γ, δ, ∈ is through the following steps, which combine clinical experience and statistical analysis. The determination of these parameters in this invention is described in detail below with specific examples.

[0082] Data Collection: Sufficient clinical data were collected, including variables Z, HR, DBP, SBP, and U, as well as the corresponding fluid intake adjustment value D. In this invention, the dataset includes information such as the type of surgery, age, gender, and underlying diseases of different patients.

[0083] Feature standardization: Since different variables have different dimensions, this invention standardizes the variables to make their mean 0 and standard deviation 1. The standardization process for the variables is as follows:

[0084]

[0085] Where μ is the mean of the variable and σ is the standard deviation.

[0086] Setting initial weighting coefficients: In this invention, the initial weighting coefficients are initially set based on clinical experience or literature, for example:

[0087] α0=0.2, β0=0.2, γ0=0.2, δ0=0.2, ∈0=0.2

[0088] Ensure that the sum of all weight coefficients is 1:

[0089] α0+β0+γ0+δ0+∈0=1

[0090] Construct the objective function:

[0091] The objective function is set to minimize the prediction error. According to the present invention, the formula for minimizing the prediction error (such as mean squared error) is as follows:

[0092]

[0093] Among them, D predicted，i D is the adjusted water intake value calculated according to the formula. actual，i This is an adjustment value based on actual water consumption.

[0094] Regression analysis:

[0095] In this invention, a model is established using linear regression or other suitable regression methods. The water intake adjustment value D is used as the dependent variable, and each physiological parameter (standardized value) is used as the independent variable. The regression coefficient of each independent variable is calculated. The formula for calculating the water intake adjustment value D is as follows:

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

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

[0098] Weight coefficient normalization:

[0099] The regression coefficients are converted into weighting coefficients such that their sum is 1. According to the present invention, the formula for converting regression coefficients into weighting coefficients is as follows:

[0100]

[0101] Verification and adjustment:

[0102] The new weight coefficients are tested on a validation dataset, the prediction error is calculated, and compared with the actual operation. When the error is unacceptable, the present invention further adjusts the weight coefficients using optimization algorithms (such as grid search, random search, etc.). According to the present invention, the adjustment formula for the weight coefficients is as follows:

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

[0104] Implementation and monitoring:

[0105] After determining the weighting coefficients, implementation in clinical practice begins. This invention systematically sets and optimizes the weighting coefficients in the water intake adjustment formula. After a period of implementation, the weighting coefficients are reassessed and adjusted to ensure their applicability. In this invention, the process of assessing and adjusting the weighting coefficients is based on extensive clinical experience or literature.

[0106] In the formula for adjusting water intake, D adjustment It is a constant, a dynamic value that varies according to the patient's physiological condition, such as changes in bioimpedance, heart rate fluctuations, changes in diastolic and systolic blood pressure, and changes in urine output. D adjustment This is used to adjust the final fluid intake value to suit clinical needs. According to the invention, this value can be adjusted under specific circumstances, such as based on clinical experience.

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

[0108] Target bioimpedance value (Z) t This value is determined based on the patient's baseline data (such as gender, age, weight, height, etc.) and clinical experience. The patient's baseline data may be derived from relevant literature or estimated using historical data.

[0109] Target water intake (D) t The target fluid intake is set based on the patient's type of surgery, preoperative condition, fluid requirements, 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 cardiac monitoring data; the clinical goals are, for example, the normal heart rate range provided by medical literature and health guidelines.

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

[0112] Weighting coefficients (α, β, γ, δ, ∈): These coefficients reflect the degree of influence of each factor on water intake adjustment. They can be derived from 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 normal physiological range. Normal physiological range is obtained, for example, by referring to data provided in medical literature and health guidelines.

[0114] To obtain the necessary empirical data for calculating the water intake adjustment value, those skilled in the art can search and refer to various channels or resource databases. Through the following methods, those skilled in the art can obtain and verify this empirical data to ensure its accurate application in practical work. Specifically, the empirical data required in this embodiment may be from hospital medical record databases and anonymized public medical record databases of relevant departments, in the form of electronic health records (EHR) data, for example. In this invention, the above parameters (water intake, urine output, bioimpedance, heart rate, blood pressure, etc.) can also be determined through a large amount of reference data provided by clinical guidelines and standards, as well as standardization organizations and certification bodies; after obtaining the necessary empirical data, each deviation value is calculated and multiplied by the corresponding weighting coefficient; all adjustment values ​​are summed to obtain the final water intake adjustment value D.

[0115] Some functions or parameters in the formula can be adjusted under specific circumstances, such as based on clinical experience, medical literature, or professional guidelines. The system in this embodiment considers multiple physiological parameters and their interrelationships, providing dynamic adjustment suggestions for perioperative patients' fluid intake. This 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 specific circumstances, such as based on clinical experience, medical literature, or professional guidelines. The system can also adjust weighting coefficients and other parameters based on individual patient differences. Information on individual patient differences can be obtained, for example, through clinical assessment, laboratory tests, health monitoring equipment, and medical records.

[0116] The system in this embodiment further incorporates an optimization algorithm. Designing the optimization algorithm L to minimize the prediction error in the water consumption adjustment formula is a crucial step. This invention provides the following example of an optimization algorithm 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 This is the adjusted water intake value calculated using the current weighting coefficients, D. actual，i This is the actual adjusted water consumption value, and n is the sample size.

[0121] 2. Gradient Calculation

[0122] In order to use the gradient descent method, this invention calculates the partial derivative (gradient) of the objective function L with respect to each weight coefficient, as shown in the following formula:

[0123]

[0124] In this invention, the chain rule and the prediction formula of linear regression are used to calculate the partial derivatives. Assume D... predicted，i Given by the following formula:

[0125]

[0126] Here, the partial derivative is obtained by applying D. predicted，i It is obtained by differentiating the weighting coefficients.

[0127] 3. Steps of the gradient descent algorithm

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

[0129] The initialization of weight coefficients is handled as follows:

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

[0131] In this invention, the initial weighting coefficients are adjusted based on clinical experience, for example.

[0132] Set the learning rate:

[0133] Choose an appropriate learning rate η (e.g., 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 a threshold:

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

[0137]

[0138] B. The formula for updating the weight coefficients 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 weighting coefficients:

[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 (e.g., 0.001), or the maximum number of iterations (e.g., 1000) is reached, then the iteration stops.

[0150] 4. Implementation and Evaluation

[0151] According to the present invention, after the iteration is completed, the new weighting coefficients are evaluated on the validation dataset to check the difference between the prediction accuracy and the actual water consumption adjustment value.

[0152] This embodiment uses the above-mentioned optimization algorithm to continuously adjust the weight coefficients based on clinical data in order to minimize prediction errors and achieve personalized and precise water intake.

[0153] Example 2

[0154] This embodiment is a further improvement of embodiment 1, and the repeated content will not be described again.

[0155] Since the human body's absorption and excretion of water is not instantaneous but a continuous process, it is necessary to sum up all urine output between two drinking times (e.g., T1 and T2) to accurately reflect the impact of each drinking session on urine volume. Preferably, in this embodiment, the single urine volume U refers to the cumulative amount of urine output within the time interval between two adjacent drinking sessions.

[0156] Suppose a user drinks V1 and V2 units of water at times T1 and T2 respectively. Between these two times, the user experiences multiple urination events. Let these urination events occur at times t1, t2, ..., t3, and the volume of urine urinated each time be U1, U2, ..., U... n .

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

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

[0159] Water intake V1 at time T1;

[0160] Water intake V2 at time T2.

[0161] 2. Record the number of urination events and the amount of urine between two drinking times:

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

[0163] The corresponding urine outputs are U1, U2, ..., U n .

[0164] 3. Calculate total urine output:

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

[0166]

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

[0168] The change in urine volume corresponding to water intake V1 is U total .

[0169] Urine volume changes after drinking water are not instantaneous; there is a certain delay. Therefore, it is necessary to sum the urine output between two adjacent time points to calculate the urine volume change caused by each instance of drinking water. This is a crucial step in reflecting changes in the user's hydration status and helps ensure the effectiveness and accuracy of hydration therapy. By recording and analyzing detailed drinking and urination data, this 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, which the user can switch between through a user 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 required parameters, such as heart rate, blood pressure, single-time water intake, and single-time urine output, through the user interface. The processing unit 300 receives the information uploaded by the user. The processing unit 300 performs a validity check on the user-input data 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 the data or suggests switching to the automatic monitoring mode.

[0171] In 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 select and switch modes via a mobile application or user interface. The system will prompt the user to confirm the switching operation and explain the operation 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 abnormalities or device malfunctions occur during the switching process, the processing unit 300 will prompt the user and suggest appropriate measures (such as restarting the device or contacting technical support).

[0173] During the routine monitoring phase, repeated water intake may have a cumulative effect on subsequent urine output. When the single urine volume U caused by a later water intake time point (e.g., T3) is less than the single urine volume U of an earlier water intake time point (e.g., T2), the processing unit 300 identifies the abnormal urination trend and issues a prompt to the user via the smart wearable device 220 or the user interface. Preferably, the prompt issued by the processing unit 300 can switch the current mode to verify whether the abnormal data is caused by a user's physical abnormality or a malfunction 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, dynamically adjust the single water intake volume and / or water intake interval in the patient's hydration plan based on the water volume change information stored in the container 100 and the patient's urine output and / or parameters reflecting blood volume status.

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

[0175] Receive the patient's status after receiving hydration therapy; based on the water volume change information V stored in container 100. C The monitoring unit 200 collects the patient's urine output U (the amount of urine excreted by the patient) and / or parameters reflecting blood volume status B, in order to dynamically adjust the single water intake D and / or water intake interval T in the patient's hydration protocol. The parameters reflecting blood volume status include: heart rate HR (the number of heartbeats per minute by the patient) and blood pressure BP (the patient's blood pressure, expressed as systolic and diastolic pressure).

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

[0177] The above technical solution can also be represented as a data lookup table based on experience, as shown in Table 1.

[0178] Table 1

[0179]

[0180] According to a preferred embodiment, the monitoring unit 200 collects parameters reflecting blood volume status, including heart rate (HR) and blood pressure (BP). Preferably, the physiological parameter information collected by the monitoring unit 200 may also include urine specific gravity. Urine specific gravity is an indicator of the solute concentration in urine and is related to the kidney's ability to reabsorb water; a lower urine specific gravity usually indicates reduced reabsorption of water by the kidneys, which may be a sign of adequate hydration. If the urine specific gravity is high, it may mean that the kidneys are reducing urine output to conserve water, which may be a signal 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 fluid intake I and single urine volume U, as reflected by the water volume change information stored in the container 100, exceeds a predetermined threshold T. th This reflects fluid retention, and a heart rate (HR) within the normal heart rate range. min HR max Within [the specified range], blood pressure (BP) is within the normal range. min BP max When the heart load is not affected, reduce the patient's single water intake (D).

[0182] 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 If ), then D decreases.

[0184] According to a preferred embodiment, the processing unit 300 is configured to: when the difference Δ between the patient's fluid intake I and single urine volume U, as reflected by the water volume change information stored in the container 100, is lower than a predetermined threshold T th Heart rate (HR) exceeding the upper limit of the normal heart rate range (HR) max Blood pressure exceeding the normal range [BP] min BP max When the heart is under increased load, the patient's single water intake (D) should be reduced, and the interval between water intakes (T) should be prolonged. Δ = IU.

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

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

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

[0188] 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 If ), 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 fluid intake I and single urine volume U, as reflected by the water volume change information stored in the container 100, is lower than a predetermined threshold T th Heart rate is within the normal heart rate range [HR] min HR max However, blood pressure exceeds the upper limit of the normal blood pressure range (BP). max When the heart is under increased load, reduce the patient's single water intake (D) or extend the interval between water intakes (T). Δ = IU.

[0191] 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 If ), then D decreases or T increases.

[0193] Normal heart rate but low blood pressure: This could be a sign of insufficient blood volume, requiring assessment of whether the patient needs more fluid replacement, especially for patients using diuretics. Normal heart rate but high blood pressure: If blood pressure is high while the heart rate remains constant, reducing hydration or extending drinking intervals may need to be considered, especially if the patient has a history of heart disease or hypertension.

[0194] According to a preferred embodiment, the auxiliary system further includes a user interface 400 for inputting the patient's diet plan. The processing unit 300 is configured to: after receiving the input diet plan, calculate the implicit water intake based on the food type and amount consumed, and then adjust the single water intake and / or water intake interval in the patient's hydration plan.

[0195] This setup prevents total fluid intake from exceeding the heart's capacity. It is particularly suitable for patients with heart failure, as excessive fluid intake can lead to a rapid increase in blood volume, placing an extra burden on the heart and hindering its pumping ability, potentially causing pulmonary congestion or peripheral edema. For example, if a patient's daily diet includes fruits, vegetables, soups, and other high-water-content foods (such as cucumbers and noodle soup), and the processing unit 300 analyzes that the patient consumed a significant amount of soup and high-water-content vegetables at lunch, the next time the patient drinks water will be delayed, and the amount consumed at that time 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 based on the patient's physiological parameter information and / or the external ambient temperature and / or ambient humidity collected by the monitoring unit 200, so as to control the patient's water intake rate and / or water consumption.

[0197] Preferably, the container 100 is provided with a heating element 113 and a cooling element 114 to heat or cool the water in the container 100, such as... Figure 2 As shown.

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

[0199] According to a preferred embodiment, the processing unit 300 is configured to: when historical physiological parameter information reflects that the patient's heart rate (HR) exceeds the normal heart rate range after each water intake [HR] min HR max [, or blood pressure exceeding the normal blood pressure range [BP]] min BP max When [the water is heated], the heating element 113 heats the water in the container 100 so that the water temperature T in the container 100 is [the desired temperature]. w Water temperature exceeding normal temperature T normal .

[0200] 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, in patient A, after each instance of drinking water, their heart rate would increase beyond the normal range, and their urine output would decrease. The processing unit 300 controls the heating element 113 to heat the water in container 100 based on historical physiological data, such as heating it from 30°C to 50°C. Due to the higher water temperature, the patient's drinking speed and volume are indirectly controlled (the patient will prefer to wait for the water to cool down before drinking).

[0203] According to a preferred embodiment, the processing unit 300 can automatically generate recommended water intake and water intervals based on monitored external environmental factors 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 via environmental sensors and integrate this information into the adjustment of the hydration scheme.

[0205] According to a preferred embodiment, a temperature sensor 112 is provided inside 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 water temperature according to the external ambient temperature and / or humidity, 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 the range of water that is comfortable for the patient to drink and to improve patient compliance.

[0207] Preferably, the heating element 113 or cooling element of the container 100 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.

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