Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical machinery, and particularly relates to a heart failure patient drinking water control system and method. BACKGROUND

[0002] Heart failure is a group of complex clinical syndromes caused by various reasons leading to abnormal changes in heart structure or function, causing ventricular systolic or diastolic dysfunction, and thus causing a group of complex clinical syndromes. Fluid retention (pulmonary congestion, systemic congestion and peripheral edema) is the main clinical manifestation. Although fluid retention is not caused by heart failure, most heart failure patients have fluid retention. Symptoms and signs of fluid retention, such as dyspnea and peripheral edema, are the main reasons for heart failure patients to be hospitalized.

[0003] The 2018 heart failure guidelines clearly point out that the amount of drinking water and intravenous infusion speed should be limited for patients with acute heart failure and obvious congestion. In order to reduce water and sodium retention and relieve symptoms, the fluid intake should be controlled within 1500mL, not more than 2000mL, and a negative balance of about 500mL should be maintained. For patients with severe pulmonary edema, the negative balance should be 1000-2000mL, and after the pulmonary congestion and edema subsided, it should gradually return to a balance of about 500mL. Patients with refractory end-stage heart failure usually have obvious water and sodium retention, and it is recommended to maintain a daily output of more than 500-1500mL. At the same time, the guidelines point out that the management of output and input requires the cooperation of patients and their families, so it is necessary to popularize the basic knowledge of heart failure among patients and their families, and to guide the diet and lifestyle of patients and their families, so as to improve the self-management ability of patients, and to improve the lifestyle of patients.

[0004] The amount of water intake is an important scientific indicator. A large number of studies have confirmed that the restriction of water intake in patients with psychological failure has been a problem, and the compliance is poor. Liquid restriction has always been considered as the cornerstone of self-management of patients with psychological failure. Even if the amount of water intake is limited by medical advice, relevant health education is improved, but patients secretly drink water, try every means to exceed the amount of water intake, and the compliance of medical behavior is poor, and the compliance of water restriction is poor. Restricting the intake of liquid can help individuals maintain fluid balance and reduce the occurrence of acute congestion-induced failure. The increase in blood volume caused by water and sodium retention is an important pathological link of heart failure, so low-sodium water-restricted diet can improve the symptoms of heart failure to some extent. The restriction of intake includes the amount of infusion, water intake and water content in food. The restriction of infusion amount is issued by the doctor in charge, and the nursing staff strictly controls the infusion amount according to the doctor's advice. The water content in food is prepared by the nutritionist according to the doctor's advice, and the liquid intake is strictly controlled according to the treatment requirements. Jia Ping et al. conducted a statistical analysis of the thirst of patients with heart failure. 4 bottles of 250 ml mineral water were prepared on the bedside cabinet without the knowledge of the patients and their families, and whether the patients exceeded the dose of water intake and the number of over-drinking were observed. According to the doctor's advice, the prepared water was placed in the heat preservation barrel, and the patient drank it in time. It is recommended that the amount of water intake of patients should be 1 ml per kilogram of body weight each time, and 2 / 3 of the total amount of water intake in the daytime and 1 / 3 of the total amount of water intake at night. The number of over-drinking and the amount of over-drinking of the two groups of patients were compared, and the observation started on the second day of hospitalization and lasted for 5 days. A numerical rating scale was used, with a test-retest reliability of 0.67-0.8545. A score of 0-10 represents different degrees, with 0 representing no thirst and 10 representing severe thirst. The scoring criteria are as follows: 0 points represent no thirst, 1-3 points represent mild thirst, 4-6 points represent moderate thirst, and 7-10 points represent severe thirst. The thirst scores, incidence of thirst and degree of thirst of the two groups of patients were compared. The results are shown in Table 1. The test group drank ice water. The control group drank warm water.

[0005] Table 1

[0006]

[0007] The results show that whether drinking warm water or ice water, heart failure patients will have more than 50% probability of thirst under the condition of artificial control of water intake frequency.

[0008] The prior art for water control of heart failure patients often relies on the patient or his third party guardian to calculate the water intake through a measuring cup, for example, the Chinese patent with publication number CN214433545U relates to a heart failure patient drinking cup, which comprises a water storage cavity and a drinking water cavity separated from the water storage cavity by a partition plate, a through hole is provided on the partition plate, and a limiting groove is provided on the inner wall of the through hole; it also includes a limiting piece located in the through hole, the limiting piece is provided with a circle of bosses on the side surface, the bosses are located in the limiting groove, the side of the partition plate facing the water storage cavity is provided with a water outlet hole one, and the side of the partition plate facing the drinking water cavity is provided with a water outlet hole two, both the water outlet hole one and the water outlet hole two are communicated with the limiting groove. The device can control the single water intake of the patient.

[0009] For heart failure patients, the quantification of water intake not only refers to the single water intake. Taking 24 hours as a cycle, medical staff will provide different water intake plans for patients with different degrees of heart failure, especially based on the patient's fluid output to determine the patient's fluid intake. The Chinese patent with publication number CN211186740U relates to a heart failure patient drinking water measuring cup, which comprises a cup body, a measuring cup cavity, a sealing cover, a capillary and a locking mechanism, the top side of the cup body is provided with an upwardly inclined water drinking part, the top surface of the water drinking part is provided with a water drinking opening, a pair of cup handles are mirror image distributed on the outer wall of the cup body, the measuring cup cavity is fixedly installed at the center of the cup body, the outer wall of the measuring cup cavity and the inner wall of the cup body form a water receiving area, the top cup wall of the measuring cup cavity expands outward to form a water pouring opening, and the bottom of the measuring cup cavity is funnel-shaped and provided with a water dripping opening. The device only controls excessive water intake and cannot guarantee that the patient can drink enough water. For heart failure patients, both sufficient water intake and insufficient water intake will affect the body. When excessive water intake, heart failure patients may have increased cardiac volume, increased cardiac preload, and aggravated heart failure, and other organs may also be enlarged, such as the lungs. When the water intake is insufficient, the body metabolism lacks water and other symptoms of water shortage are caused.

[0010] Based on the water intake prompt for heart failure patients, the present application provides a heart failure patient water control system.

[0011] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, the applicant has studied a large number of literatures and patents when making the present application, but due to the limited space, all the details and contents are not listed in detail, which does not mean that the present application does not have these characteristics of the prior art, on the contrary, the present application has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art in the background art. SUMMARY

[0012] The present application relates to a water drinking device, especially a water drinking control device, and a water quantity measuring device.

[0013] Patients in the middle and late stage of heart failure need to strictly control the daily water intake, and drink water in small amounts and multiple times. Due to the difficulty of accurately controlling the water intake, combined with the large artificial statistical error, the water control effect of heart failure is not good, and the patient's heart failure is aggravated. Therefore, a device with propaganda function is needed in clinical practice, which can strictly control the water intake according to the different conditions of patients and remind patients to drink water, water heating and insulation. Heart failure patients need to strictly control the daily water intake, and drink water in small amounts and multiple times. Large mouthfuls of water. Clinically, patients are reminded to drink water through regular patrols to avoid neglecting to drink water due to distraction, and the hourly water intake is strictly controlled to avoid excessive water intake leading to gastrointestinal discomfort. Due to the difficulty of accurately controlling the water intake by patients and their families, combined with the need for patients to drink water in small amounts and multiple times, the frequency and water intake statistics are tedious, and the artificial statistical error is large, which can easily affect the patient's recovery process after surgery. In addition, the water temperature suitable for drinking water needs to be controlled multiple times, and manual temperature adjustment will not only make it difficult to count the water intake, but also waste resources. In addition, patients may not drink all the water due to physical discomfort, and in this case, the un-drunk water cannot be counted, increasing the error in daily water intake statistics. Therefore, a device with propaganda function is needed in clinical practice, which can strictly control the water intake according to the different conditions of patients and remind patients to drink water, water heating and insulation.

[0014] The common symptoms of patients in the middle and late stage of heart failure are rapid breathing, rapid heartbeat, sitting respiration, inability to lie flat, restlessness, cyanosis of the lips, general edema, reduced urine output, and even mental confusion due to cerebral hypoxia. Therefore, when the patient's water intake plan cannot be normally implemented, relying solely on reminders may not help patients with blurred consciousness to normally execute the water intake plan. The present application provides a water intake control system that can seek help from a third party based on multiple warnings when the planning of the water intake plan reaches a time that cannot be delayed, so as to help the current patient execute the water intake plan under the supervision of the third party.

[0015] The water intake part is preferably a water cup, and the power components in the water cup operate by relying on the charging battery arranged in the water cup. The system confirms that the patient has a water intake motive based on the patient's water intake action, thereby triggering the weight sensing component to start working, which on the one hand reduces the energy consumption of the dual-sensing device and increases the endurance time of the water cup; on the other hand, the simultaneous monitoring of the dual-sensor will bring a large amount of data to be processed to the central processor, which reduces the reaction speed of the central processor and increases the waiting time for instruction feedback during use.

[0016] A heart failure patient water intake control system includes at least a water intake part capable of sensing changes in the water in the patient's water cup, a central processor, and a water outlet part controlled by the central processor to adjust the water outlet amount and water temperature of the water added to the water intake part.

[0017] The drinking water part is provided with a gravity sensing component and a motion sensing component. When the central processor confirms that the patient has a drinking water motive based on the information about the patient's drinking water motion provided by the motion sensing component, the central processor triggers the gravity sensing component to monitor the weight change of the drinking water part. In response to the information about the patient's insufficient drinking water times or insufficient water volume provided by the drinking water part, the central processor adjusts the initial drinking water plan of the patient and generates an alarm to prompt the patient to drink water.

[0018] The amount of drinking water for heart failure patients is limited. In order to ensure that the patient can intake the amount of drinking water that meets the life needs while avoiding excessive drinking water that burdens the kidney that is in functional decline, medical staff need to develop different drinking water plans for patients according to the development degree of heart failure of the patients. In the prior art, such drinking water plans often rely on the autonomous execution of patients or guardians of the patients. On the one hand, the drinking water plan process is complicated, and the autonomous execution relying on manual work may have errors or omissions. On the other hand, the patient may have the problem of excessive drinking in a single drinking process, for example, the single drinking is limited to no more than 200 mL, but the patient drinks 300 mL of water in a single drinking when 500 mL of water is stored in the cup, and this problem can only be found after the patient finishes drinking.

[0019] From the perspective of the patient, single excessive drinking will lead to a decrease in the amount of subsequent drinking water, and increase the probability of subsequent excessive drinking. In the life of the patient, water not only meets the life needs, but also helps when the patient chokes while eating. In special circumstances, the patient may need to drink a planned amount of water. From the perspective of medical staff, single excessive drinking can cause metabolic burden for some severe heart failure patients, and there is a high probability of water and sodium retention. The cumulative excessive drinking water will also affect the kidney of the light heart failure patient, especially when the patient's output is less than the intake, the part of the excessive drinking water is stored in the human body, causing edema. Therefore, the present application separates the functions of water outlet and drinking water, and the patient needs to authorize the water outlet for each drinking. The water outlet provides the patient with the amount of water for this drinking according to the drinking water plan, and controls the single drinking amount of the patient through automatic equipment. The system also sets a detection unit in the drinking water part to determine whether the patient drinks water by combining the patient's motion and the change of the water amount of the drinking water part, so as to avoid the need for other people to look after the patient to complete each drinking, and to record and report in time when the patient wastes the water or does not drink the water, so as to realize the fine management of the drinking water of the patient.

[0020] When the remaining drinking water time of the patient is sufficient but the qualified drinking water amount is not completed for more than the first number threshold, the central processor triggers the drinking water part to broadcast the propaganda voice and generates the first level alarm to prompt the patient to drink water. Timed and quantitative drinking water does not burden the body of the heart failure patient.

[0021] Heart failure also has a certain impact on kidney function. Heart failure is a symptom of the development of organic heart disease to the later stage. Due to the weakening of the contractile force of the heart, the burden of the heart is increased, resulting in impaired cardiac function. Due to the significant reduction in cardiac ejection, the blood supply to the organs of the body, including the kidneys and the brain, will also be significantly reduced. The function of the kidney is to excrete the metabolic waste in the body, including urea nitrogen and creatinine, and the maintenance of kidney function depends on sufficient blood volume of the kidney. When the patient is a heart failure patient, a single sudden excessive water intake will put a great burden on the patient's kidney, and in severe cases, it can even cause the patient to edema. Therefore, even if there is enough time left for water intake, in order to avoid a sudden increase in the amount of water intake in the subsequent period of time, the system sets the first level alarm in the case that the single specified water intake plan is not completed.

[0022] When the remaining time of the patient is the minimum time for the preset single water intake to reach the maximum value, the central processor generates a second level alarm to assist the patient in drinking water, wherein the receiving terminal of the second level alarm belongs to at least a third party guardian of the patient or a medical staff responsible for the patient.

[0023] Due to the reduction of cardiac output when the patient has heart failure, the blood flow supply to the brain is reduced, which will cause the patient to have intermittent unconsciousness, slow reaction and irritability, and in severe cases, the patient can even be in a coma. When the patient has the above-mentioned unconsciousness, the water intake part will not respond even if it sends an alarm. When such a situation occurs, the manual supervision of the third party guardian or the medical staff on the patient's water intake behavior becomes extremely important. When the patient misses the first level alarm for several times and the remaining time is the minimum time for the preset single water intake to reach the maximum value, the relevant information is sent to the terminal of the third party guardian or the medical staff to prompt the third party guardian or the medical staff with normal thinking to supervise the patient's water intake.

[0024] The system provided by the present application can be used to provide a water intake plan for a patient with heart failure in the middle and late stages. The system can implement an initial water intake plan based on the medical order, but when the patient repeatedly fails to cooperate with the water intake action, the system can provide at least one prompt for the patient through the water intake part, so that the patient can generate a water intake awareness, and adjust the remaining water intake plan based on the unwatered action of this time, to ensure that the patient can complete the specified water intake amount and water intake times within the planned time. When the patient suddenly has blurred consciousness or memory loss and cannot clearly follow the system instructions to drink water, the system can notify the third party guardian to supervise the patient to complete the water intake plan based on the condition that the remaining time of the patient is the minimum time for the preset single water intake to reach the maximum value.

[0025] According to a preferred embodiment, in response to the complete presentation of the first-level alarm to the patient, the central processor increases the number of water drinking of the patient based on the remaining water drinking time. The first-level alarm is used to prompt the patient to complete the current water drinking plan. Under the prompt of the first-level alarm, the patient may drink water, and the first-level alarm will stop even if it has not been broadcasted completely after the patient finishes drinking water. When the first-level alarm is completely presented, it indicates that the patient has not drunk water and is likely not to drink water, so the central processor attributes the water drinking amount of this time to the non-water drinking amount, and adjusts the water drinking plan for the patient based on the non-water drinking amount and the recommended single water drinking amount in the medical order.

[0026] According to a preferred embodiment, the present patent relates to a ward or ICU water drinking system, which comprises a water outlet and a water drinking part bound to the patient's identity. Each time the water is discharged, the patient can check the patient's identity information by scanning the code, swiping the card, fingerprint scanning or scanning the specific identification code of the water cup bound to the patient, automatically switch to the water drinking information corresponding to the patient, and make the water outlet discharge water according to the water drinking information. The central processor can measure the total amount of water drinking, and when used, it is used for a single patient. The most suitable water drinking interval of the patient is input by medical staff in advance. Preferably, the central processor sets the daily water drinking times according to the total water drinking amount and the single water drinking amount interval, and adjusts the water drinking amount according to the patient's work and rest, such as appropriately increasing the water drinking amount after meals to supplement water, and reducing the water drinking amount near the night rest.

[0027] According to a preferred embodiment, the central processor is capable of receiving the heart rate detection signal of the patient, wherein the central processor generates a result of judging that the first level alarm is ineffective due to the abnormal state of the patient in combination with the trajectory of the drinking water part transmitted by the motion sensing assembly and the heart rate detection signal of the patient. Based on the result of judging that the first level alarm is ineffective, the central processor receives information transmitted by the gravity sensing assembly of the drinking water part to confirm the drinking water deficiency amount of the drinking water part, and updates the initial drinking water plan based on the drinking water deficiency amount of the drinking water part. Due to the problem of cerebral ischemia, heart failure patients have intermittent abnormal states of unconsciousness or mania. Patients in this state will have a strong reaction to external stimuli, such as breaking a cup. When the first level alarm sounds, the patient in an abnormal state may break the cup. Heart failure patients will always wear an electrocardiogram monitoring device in the ward to ensure that heart failure patients can be rescued in time when their heart rate is a problem. The central processor of the present application can receive patient heart rate data. When the patient in an abnormal state makes a big movement, the patient's emotions and actions will cause the heart rate to increase, and the central processor can judge the state of the patient and the state of the cup based on the trajectory of the cup movement and the increase of the patient's heart rate. When the patient is in an abnormal state, the central processor will send an instruction to the drinking water part to stop the drinking water part from emitting images, lights or sounds that stimulate the patient, and provide a calm environment for the patient. At the same time, the weight sensor of the drinking water part can detect the change of the water amount in the drinking water part based on the instruction to determine whether water leakage occurs. The above setting can avoid the emotional stimulation of the alarm to the patient. Heart failure patients need to rest, and uncomfortable external stimuli are extremely likely to cause the patient to have a heart attack or aggravate the patient's heart failure problem, so the system provided by the present application can combine the patient's emotions and actions to remind the patient to drink water at the appropriate time, and avoid excessive stimulation to the patient.

[0028] According to a preferred embodiment, based on the result of the judgment of the failure of the first level alarm, the central processor continuously receives the heart rate detection signal of the patient and re-sends the first level alarm when the heart rate detection signal of the patient enters a first heart rate threshold. Based on the occurrence of the failure of the first level alarm, the central processor can select other methods to display the first level alarm, wherein the methods are less stimulating than the method used to display the first level alarm last time. When the patient is calm, the patient's desire to drink water will increase due to the increase of the heart rate. At this time, the system can display the first level alarm in a less stimulating way than the last time to prompt the patient to drink water. On the one hand, this time point is the time when the patient needs to drink water; on the other hand, after the patient vents his emotions or performs a large action, the patient's metabolism will be too large due to excessive heartbeat, so the body is in a state of water thirst, therefore, after the patient calms down, it is appropriate for the system to prompt the patient to drink water, and the patient has a great possibility to drink water. Preferably, the most stimulating method in the first level alarm is the alarm sound. The second stimulating method in the first level alarm is the voice propaganda. The weak stimulating method in the first level alarm is the light blinking.

[0029] According to a preferred embodiment, the sensor for detecting the change of the water weight can also be a light detector. Through the light reflection principle, the light detector measures the scale on the water cup corresponding to the drinking water, and calculates the volume difference of the drinking water before and after the water pouring action, and then obtains the pouring amount.

[0030] According to a preferred embodiment, the undrunk water amount also includes the remaining water amount in the drinking part. When the next water is added, the central processor will first identify the content of the drinking water in the drinking part, and if there is undrunk water in the drinking part, the central processor will calculate the water volume to be added by calculating the water volume in the drinking part. Preferably, when there is remaining water in the drinking part, the central processor does not change the current drinking plan, but only supplements the drinking amount of the patient in the current drinking plan to the drinking part, and the remaining water in the drinking part is included in the undrunk water amount, and the subsequent single drinking times are redistributed after the redistribution.

[0031] According to a preferred embodiment, according to the temperature in the drinking part, the central processor will adjust the temperature of the water to be added according to the corresponding temperature in the drinking part, so that the patient can drink the most suitable temperature drinking water when drinking.

[0032] According to a preferred embodiment, the central processor receives real-time monitoring data of the urine amount of the patient, and adjusts the remaining single drinking amount or the remaining drinking times of the patient in the day when the urine amount of the patient is updated without changing the total amount of drinking water of the patient in the day. The liquid in and out of the human body needs to be balanced. When the patient has liquid discharge, it means that the patient's body is healthy and the body fluid can be supplemented. The central processor can adjust the drinking time or times based on the increase of the discharged liquid.

[0033] According to a preferred embodiment, when the single water drinking amount of the patient is within the interval and the remaining water drinking time is sufficient, the central processor provides the patient with drinking water in compliance with the current water drinking amount based on the initial water drinking plan of the patient. The water outlet part in the dormant state sends information of starting work to the central processor upon receiving the instruction authorized by the patient, and provides the specified volume of drinking water to the water drinking part of the patient based on the water outlet instruction sent by the central processor. The initial water drinking plan is generated by the central processor capable of receiving the medical order related to the patient sent from the medical staff terminal, wherein the medical order at least contains the water drinking schedule of the patient, the total daily water drinking amount of the patient and the single water drinking amount of the patient.

[0034] A water drinking control method for heart failure patients, the method comprising the following steps:

[0035] Based on the medical order, a water drinking plan related to the preset water drinking time, the preset total daily water drinking amount and the preset single water drinking amount is generated; by monitoring the water drinking times and the water drinking amount of the patient, after each time the patient completes the water drinking action, the water drinking plan of the patient can be adjusted based on the historical water drinking record of the patient and the water drinking amount of the patient this time, wherein when the remaining water drinking time of the patient is sufficient but the qualified water drinking amount is not completed for more than a first number threshold, a first level alarm is generated to prompt the patient to drink water in the form of broadcasting health education voice; when the remaining time of the patient is the minimum time for the preset single water drinking amount to reach the maximum value, a second level alarm is generated to assist the patient to drink water, wherein the second level alarm is used to prompt at least the third party guardian of the patient or the medical staff in charge to supervise the completion of the water drinking plan of the patient on the same day.

[0036] The system can record the water drinking amount and the water drinking times of the patient, and provide the water drinking basis for the medical staff, and when the patient is treated based on kidney failure, the medical staff can plan the infusion or urination monitoring based on the historical water drinking record.

[0039] LIST OF REFERENCE NUMERALS

[0040] 100: central processor; 200: water outlet part; 300: water drinking part. DETAILED DESCRIPTION

[0041] The following will be described in detail with reference to the accompanying drawings.

[0042] The application provides a water drinking control system for heart failure patients, which comprises a water drinking part 300 capable of sensing the change of water in a patient's cup, a central processor 100, and a water outlet part 200 capable of adjusting the water volume and temperature of water added to the water drinking part 300 under the control of the central processor 100, as shown in the figure. Figure 1 Preferably, the water drinking part 300 is a water cup with a scale and a sensing device. The water outlet part 200 is a drinking water storage device with a water outlet control valve. The water outlet part 200 can be connected to a water pipe and heat the water in the water pipe to ensure that the patient can drink high-temperature boiled water. The water outlet part 200 can store normal-temperature boiled water, and the temperature of the drinking water can be controlled by mixing high-temperature boiled water and normal-temperature boiled water when the patient needs drinking water of other temperatures. The water drinking part 300 can at least sense the change of water volume and temperature in the part.

[0043] The water drinking part 300 is provided with a gravity sensing assembly and a motion sensing assembly. When the central processor 100 confirms that the patient has a water drinking motive based on the information about the patient's water drinking motion provided by the motion sensing assembly, the central processor 100 triggers the gravity sensing assembly to detect the weight change of the water drinking part 300. In response to the information about the patient's too few times of drinking water or too low water volume provided by the water drinking part 300, the central processor 100 adjusts the initial water drinking plan of the patient and generates an alarm to prompt the patient to drink water. Preferably, the data content transmitted by the motion sensing assembly at least includes three-dimensional space coordinate data of the water drinking part 300, i.e., the coordinates of the water drinking part 300 corresponding to x, y, and z axes, respectively. Preferably, the coordinate system in which the water drinking part 300 is located can be flexibly selected according to the actual application scenario. The motion sensing assembly can be a three-axis acceleration sensor. The motion sensing assembly can be used to record the spatial running track data of the patient grabbing the integrated or water drinking part 300 provided with the motion sensing assembly in the air. Preferably, the spatial running track data can include the time length of the pause generated in the process of the patient grabbing the water drinking part 300, the distance of one-time motion, the moving track of the patient's hand moving from one position to another position, and other time sequence signals. Preferably, one-time motion is a smooth motion without pause throughout the process. By this method, the patient's action of drinking water or dropping the cup can be accurately distinguished. When the motion sensing assembly detects the displacement of the water drinking part 300 each time, the gravity sensing assembly automatically triggers to detect the weight of the current water drinking part 300 and sends it to the central processor 100. The central processor 100 can obtain the water drinking volume of the patient based on the last weight and the current weight.

[0044] When the patient has sufficient remaining water drinking time but has not completed the qualified water drinking amount for more than a first number threshold, the central processor 100 triggers the water drinking unit 300 to broadcast a health education voice and generates a first level alert to remind the patient to drink water. The first level alert can provide a warning to the patient in the form of sound, image or light. For patients with severe heart failure, the first level alert can also connect to an image display module in the ward, such as a television, to provide the patient with a video showing the dangers of excessive or insufficient water drinking. Preferably, the video can only play the dangers of excessive water drinking by the patient based on the patient's excessive drinking at the time. Preferably, the first number threshold can be 2 times.

[0045] When the patient has a minimum time left for the maximum single water drinking amount to be reached, the central processor 100 generates a second level alert to assist the patient in drinking water, wherein the receiving terminal of the second level alert belongs to at least a third party guardian of the patient or a medical staff responsible for the patient. Preferably, the maximum single water drinking amount can be 200mL. The minimum time left for the patient can be 5h.

[0046] The system provided in the present application can be used to provide a water drinking plan for patients with advanced heart failure. The system can implement an initial water drinking plan based on a medical order, but when the patient repeatedly shows an action of not cooperating with water drinking, the system can provide at least one reminder to the patient through the water drinking unit 300, so that the patient can generate a water drinking awareness, and adjust the remaining water drinking plan based on the action of not drinking water at the time, to ensure that the patient can complete the specified water drinking amount and water drinking times within the planned time. When the patient suddenly has confusion or memory loss and cannot clearly follow the system's instructions to drink water, the system can notify a third party guardian to supervise the patient to complete the water drinking plan based on the condition that the patient has a minimum time left for the maximum single water drinking amount to be reached.

[0047] According to a preferred embodiment, in response to complete presentation of the first level alert to the patient, the central processor 100 increases the number of water drinking times of the patient based on the remaining water drinking time. Complete presentation of the first level alert to the patient means that the image is played in its entirety or the sound is continuously played for more than 10s.

[0048] According to a preferred embodiment, the central processor 100 is capable of receiving the heart rate detection signal of the patient, wherein the central processor 100 combines the trajectory related to the drinking water part 300 transmitted by the motion sensing assembly and the heart rate detection signal of the patient to generate a result of determining that the first level alarm is ineffective due to the abnormal state of the patient. The heart rate of the heart failure patient is monitored in real time by the electrocardiogram monitoring device. The electrocardiogram monitoring device is capable of sending the monitored heart rate data to the central processor 100. Preferably, the electrocardiogram monitoring device is capable of sending the heart rate data of the patient to the central processor 100 at a cycle of 1 time / min. When the heart rate data increases by more than 10%, the central processor 100 generates a result of determining that the patient is in an abnormal state of emotional excitement or large motion.

[0049] According to a preferred embodiment, based on the result of determining that the first level alarm is ineffective, the central processor 100 continues to receive the heart rate detection signal of the patient and re-sends the first level alarm when the heart rate detection signal of the patient enters a first heart rate threshold. The first level alarm being ineffective indicates that the current drinking water plan is not implemented. The heart rate data will gradually decrease as the patient's emotion stabilizes or no longer implements large motion. The first heart rate threshold can be in the range of 60-100 times / min.

[0050] According to a preferred embodiment, based on the result of determining that the first level alarm is ineffective, the central processor 100 receives information transmitted by the gravity sensing assembly of the drinking water part 300 to confirm the missing amount of drinking water of the drinking water part 300, and updates the initial drinking water plan based on the missing amount of drinking water of the drinking water part 300. At this time, the missing amount of drinking water is the amount of wasted drinking water, and the missing amount of this time will not be counted as the drinking amount of the patient. Generally, when the drinking water is missing, the system defaults that the patient has drunk the amount of drinking water, and the system will determine whether the drinking water plan is implemented based on this situation. However, based on the above situation, the system will prevent or not implement the update of the drinking water plan, i.e. not consider that the current drinking water plan is completed.

[0051] According to a preferred embodiment, the central processor 100 receives real-time monitoring data of the patient's urine output, and adjusts the patient's remaining single drinking water amount or the remaining drinking water times of the day when the patient's urine output is updated, without changing the patient's total daily drinking water amount. The patient's intake and output needs to be balanced based on the body condition. After the patient produces urine, the central processor 100 can increase the patient's drinking water amount within the range of the single allowed drinking amount, and reduce the subsequent drinking amount based on the increase of the current drinking amount. For example, when the patient's urine bag detection device sends the central processor 100 information about the patient's increased urine, the central processor 100 adjusts the last drinking water plan, and adjusts the single 100mL drinking water amount to 120mL or 140mL. The total drinking water amount is in the range of 1000-2000mL. Based on the increase of the current drinking water amount, the patient is timely rehydrated. The above adjustment scheme increases the degree of refinement of the patient's drinking water regulation.

[0052] According to a preferred embodiment, when the patient's single drinking water amount is within the interval and the remaining drinking water time is sufficient, the central processor 100 provides the patient with drinking water that meets the current drinking water amount based on the patient's initial drinking water plan. When the patient drinks water according to the specified plan, the central processor 100 triggers the next drinking water plan when each drinking water plan is completed, and when the water outlet 200 is opened based on the patient's authorization, the water outlet 200 can receive the central processor 100's instructions to provide the patient with the specified amount of drinking water according to the plan.

[0053] According to a preferred embodiment, the water outlet 200 in the sleep state sends the central processor 100 information about starting work when receiving the patient's authorization instructions, and provides the patient's drinking water outlet 300 with a specified volume of drinking water based on the water outlet instructions sent by the central processor 100. The initial drinking water plan is generated based on the medical orders related to the patient sent by the medical staff terminal received by the central processor 100, wherein the medical orders at least include the patient's drinking schedule, the patient's total daily drinking water amount, and the patient's single drinking water amount. The doctor can adjust the patient's drinking water plan through his own terminal system according to the patient's physical development each time, and the plan can only be adjusted by medical staff to avoid the patient or his guardian arbitrarily changing the drinking water plan and causing the patient to overdrink.

[0054] For the water nursing of heart failure patients, the existing technology is commonly realized by a special nursing staff supervision mode, for example, the nursing staff of a hospital or the family of a heart failure patient who has received certain nursing training as a nursing party to supervise the water drinking activity of the heart failure patient, but this mode is very labor-intensive, and in many cases, the patient drinking water cannot be seen or cannot be seen by the nursing party. Therefore, the existing technology may also consider using some devices to remind heart failure patients to drink water, such as using some intelligent water drinking cups already sold on the market, but the existing intelligent water drinking cups have very simple functions, basically only have the function of reminding the user to drink water according to the user's set time, and a small number of intelligent water cups may also have the functions of detecting the water drinking amount and the remaining water amount. Such a water cup can meet the drinking water needs of a normal person, but for heart failure patients, such an intelligent water cup is difficult to apply, because in addition to the basic requirement of a certain amount of water drinking per day as a normal person, the nursing party is more concerned about the water drinking action mode of the heart failure patient. The trachea and esophagus in the human body are two major channels connected to the outside world, and the trachea and esophagus share a channel at the throat of the human body. When a person drinks water or eats food, the epiglottis cartilage will cover the trachea, and a short breath will occur. After the food or drinking water passes through the pharynx, the epiglottis cartilage will reopen, allowing the person to continue breathing. When continuously drinking water, a person will be in a breath-holding state for a long time, which may not have too much impact on a normal person, but for heart failure patients, a long breath-holding state is a major cause of abnormal heart rate. One of the important symptoms of heart failure is the decline in heart function, which affects the circulation of blood and oxygen in the patient's body, and the patient is very prone to breathing difficulties. On this basis, the short breath of the patient when drinking water will further increase the risk of oxygen deficiency of the patient. However, each heart failure patient has different conditions, and each person has their own drinking habit. Some people are used to drinking water in large mouthfuls, some people are used to drinking water in small mouthfuls, and some people are used to drinking water in one gulp. However, the risk of oxygen deficiency caused by breath-holding when drinking water is not known to the patient, although the heart failure patient is encouraged to drink water in small mouthfuls, the specific amount of small mouthfuls that each person can tolerate is different, especially for the nursing staff in the perspective of others, it is more difficult to know, thus causing nursing troubles.

[0055] Based on the above problems, preferably, the present scheme gives the following method:

[0056] In the first time period, the central processor 100 obtains the first action mode parameter related to the patient's water drinking by using the action sensing assembly. At the same time, the central processor 100 obtains the first electrocardio parameter of the patient by using the electrocardio sensing assembly, and stores the first electrocardio parameter in a manner of time sequence correlation with the first action mode parameter;

[0057] Jointly analyzing the first electrocardio parameter and the first action mode parameter: setting a detection value, when a certain data in the first electrocardio parameter exceeds the detection value, marking the corresponding parameter in the first action mode parameter as a warning parameter;

[0058] In the second time period, the central processor 100 obtains the second action mode parameter related to the patient drinking water by using the action sensing assembly, and when a certain parameter in the second action mode parameter is detected to be greater than the warning parameter, an alarm signal is generated and sent to the outside.

[0059] The parameter types recorded by the first action mode parameter and the second action mode parameter can be the same, and in the case of different time periods, the two parameters can be regarded as two versions. The action mode parameter may, for example, include the drinking water time of the patient, i.e. the time from starting to drink to swallowing, during which the patient's pharynx has water passing through all the time. The detection method can be to detect the inclination of the water cup by using the action sensing assembly, to monitor the weight change of the water cup content by using the gravity sensing assembly, or even to realize it by taking the sound of the patient drinking water and the video picture as the detection basis. When the drinking water time of the patient is obtained, the first electrocardio parameter of the patient is obtained at the same time, which may, for example, include the heart rate parameter of the patient. In the analysis, a detection value is set, which may, for example, be a normal heart rate reference value. In the analysis, when the heart rate of the first electrocardio parameter at a certain time is detected to exceed the normal heart rate reference value, it indicates that the heart rate of the patient at this time is increased, which is likely to be caused by hypoxia due to the patient's long-time drinking water and holding breath, thereby causing the heart rate to be fast, which can be regarded as a dangerous signal, and therefore the device marks the drinking water action mode parameter of the patient at this time to form a warning parameter. In the second time period, which can be the time period in which the patient normally uses the device, the device detects the drinking water action mode parameter of the patient, and when the warning parameter appears, an alarm is automatically sent. Preferably, the steps in the first time period can be repeated to obtain an updated warning parameter distribution result.

[0060] From the above scheme, the drinking water adaptability of each heart failure patient is automatically monitored, i.e. within the range of the physiological indicators recommended by medicine (here, the electrocardio indicator is taken as the main concern), the personal drinking water habit of the patient can be executed to what extent, the alarm sending condition can be automatically adjusted according to the personal state of the patient and the drinking water habit, so as to better adapt to the personal characteristics of each patient, and on the basis of trying not to affect the drinking water habit of the patient, the health care of the patient is realized, which has a significant contribution to the intelligent monitoring system realizing "unconscious detection" and "unconscious prompting".

[0061] Embodiment 1

[0062] The present application relates to a drinking water monitoring device. The present application relates to a water quantity monitoring device. The present application relates to a drinking water system suitable for clinical patients.

[0063] The system of this invention is suitable for patients with heart failure of class II.

[0064] The patient possesses a personal identification card. Each time the patient needs to drink water, they swipe their personal identification card at the water dispenser 200 to authorize the dispenser.

[0065] When a patient is hospitalized, the doctor provides a hydration plan in the prescription based on the patient's heart failure progression: a total daily water intake of 1300mL, with 10 water intakes per day, including 200mL of water for breakfast, lunch, and dinner, and 100mL of water for other time intervals.

[0066] like Figure 2 The procedure shown is as follows: when the scheduled drinking time arrives, the patient carries the drinking device 300 to the water dispensing unit 200 to collect water. The patient swipes their card, and the water dispensing unit 200 provides 100mL of drinking water to the drinking device 300 based on the drinking plan. The drinking device 300 begins monitoring. The central processor 100 receives data from the drinking device 300 related to the movement trajectory and water weight. When the data indicates that the drinking device 300 has shifted and the water weight has decreased to 0, the central processor 100 considers the patient to have completed the drinking session.

[0067] Before a meal, the patient takes the drinking water dispenser 300 to the water outlet 200 to fill with water. The water outlet 200 provides 200mL of water to the drinking water dispenser 300. When the central processor 100 receives a message that the movement trajectory has not changed and the water weight has not changed, and this situation continues for 30 minutes, the central processor 100 controls the drinking water dispenser 300 to emit a sound to prompt the patient to drink water.

[0068] When the central processor 100 receives a sudden increase in the patient's heart rate from 90 beats / min to 120 beats / min, accompanied by an arc-shaped displacement of the drinking fountain 300, the central processor 100 controls the drinking fountain 300 to stop emitting sound. The drinking fountain 300 detects its internal weight and finds no change in weight; the central processor 100 confirms water leakage and continues to monitor the patient's heart rate.

[0069] When the patient's heart rate returns to 93 beats / min and remains unchanged for 10 minutes, the central processor 100 controls the drinking unit 300 to prompt the patient to drink water by flashing lights.
