Description

Technical Field

[0001] The present invention relates to the technical field of heart failure, and in particular to a method, system and device for monitoring salt and water intake in patients with heart failure. Background Art

[0002] Heart failure, as a serious cardiovascular disease, poses a huge threat to the health of patients. Controlling salt intake is a crucial part of the treatment and management of heart failure. Excessive salt intake can lead to fluid retention in the body, increase the burden on the heart, and aggravate the symptoms of heart failure. However, traditional salt intake monitoring methods have many limitations.

[0003] At present, patients can only rely on self-estimation to judge their salt intake, which is not accurate and prone to large errors. For example, it is difficult for patients to accurately grasp the amount of salt added during cooking, and it is also difficult to detect the invisible salt in some processed foods. Patients may find it difficult to strictly control their salt and water intake due to lack of professional knowledge or insufficient self-management awareness. At the same time, it is difficult for medical staff to fully understand the patient's daily diet and changes in their condition, and it is difficult to provide personalized treatment advice. It is difficult for patients to record and analyze their long-term salt intake and cannot intuitively understand their diet control. For medical staff, it is also difficult to fully grasp the patient's diet, so they cannot adjust the treatment plan in time. At the same time, the lack of remote monitoring means also makes it impossible for medical staff to understand the patient's salt intake in real time, which is not conducive to the timely management and treatment of the disease.

[0044] Example 1

[0045] A method for monitoring salt and water intake in a heart failure patient as shown in the figure comprises the following steps:

[0046] Set the description of the condition of heart failure patients, and set the standard value of daily salt intake and daily water intake for heart failure patients;

[0047] Obtain the daily salt intake, water intake and water excretion of heart failure patients; obtain the description of medication and condition uploaded by the patient every day;

[0048] When the patient's salt intake and water intake exceed the set daily salt intake standard value and daily water intake standard value, a salt water intake exceeding standard reminder is issued;

[0049] Medical staff provide nutritional advice and salt intake recommendations to patients based on their salt intake, water intake, water excretion, medication descriptions, and disease status.

[0050] First, set the condition description and the daily salt intake standard value and daily water intake standard value for heart failure patients. Through the information uploaded by the patient daily, such as salt intake, water intake, water excretion, medication description and condition description, the system can monitor the patient's salt water intake and physical condition in real time. When the patient's salt intake and water intake exceed the set standard values, the system will issue a reminder of excessive salt water intake. Medical staff can comprehensively analyze the patient's specific situation based on these detailed information uploaded by the patient, and provide personalized nutrition advice and salt intake advice to better manage the patient's heart failure.

[0051] Example 2

[0052] This embodiment is different from Embodiment 1 in that obtaining the daily salt intake of a heart failure patient comprises the following steps:

[0053] Set up a salt tank for weighing salt;

[0054] Get the weight of the salt tank before taking salt, get the weight of the salt spoon before taking salt, and take salt with the salt spoon;

[0055] Get the weight of the salt tank after taking out the salt, and get the weight of the salt spoon after taking out the salt;

[0056] The weight difference of the salt tank before and after taking salt is calculated as the first salt intake; the weight difference of the salt spoon before and after taking salt is calculated as the second salt intake;

[0057] The average of the first salt intake and the second salt intake is calculated as the salt intake, and the salt intake is stored.

[0058] First, before the patient prepares to take salt for cooking or eating, accurately obtain the weight of the salt tank before taking salt and the weight of the salt spoon before taking salt. Then, the patient takes a certain amount of salt from the salt tank with a salt spoon for cooking or direct consumption. After the salt is taken, the weighing equipment is used again to measure the weight of the salt tank after taking salt and the weight of the salt spoon after taking salt. By calculating the weight difference before and after the salt tank takes salt, the first salt intake based on the change of the salt tank is obtained; at the same time, the weight difference before and after the salt spoon takes salt is calculated to obtain the second salt intake based on the change of the salt spoon. Finally, the first salt intake and the second salt intake are averaged to determine the salt intake of this salt taking, and the data is stored for subsequent analysis and management. By measuring and calculating the weight from the two perspectives of the salt tank and the salt spoon, the actual salt intake of the patient can be determined more accurately, avoiding the errors that may be caused by a single measurement method, and providing extremely accurate data support for the dietary management of heart failure patients.

[0059] Example 3

[0060] A salt and water intake monitoring device for a heart failure patient, comprising a first weighing module, a second weighing module, a first calculation module, a second calculation module, a wireless communication module, a cloud management platform, and a query client;

[0061] The first weighing module is used to obtain the weight of the salt tank before taking salt and the weight of the salt tank after taking salt;

[0062] The second weighing module is used to obtain the weight of the salt spoon before taking the salt and the weight of the salt spoon after taking the salt;

[0063] The first calculation module is used to calculate the weight difference of the salt tank before and after taking salt as the first salt intake, and calculate the weight difference of the salt spoon before and after taking salt as the second salt intake;

[0064] The second calculation module is used to calculate the average of the first salt intake and the second salt intake as the salt intake;

[0065] The wireless communication module is used to transmit the data of the salt intake calculated by the second calculation module to the cloud management platform, and the cloud management platform stores the data of the salt intake;

[0066] The query client is used to query salt intake data from the cloud management platform.

[0067] The first weighing module continuously monitors the weight change of the salt tank through the built-in high-precision sensor, records the initial weight of the salt tank before the patient takes the salt, and measures and records the current weight of the salt tank again after taking the salt. The second weighing module also uses the sensor to monitor the weight of the salt spoon, and obtains the weight of the salt spoon before and after taking the salt. The first calculation module receives data from the first weighing module and the second weighing module, calculates the weight difference before and after the salt tank takes the salt, and uses it as the first salt intake; at the same time, the weight difference before and after the salt spoon takes the salt is calculated as the second salt intake. The second calculation module averages the first salt intake and the second salt intake to obtain the final salt intake. The wireless communication module transmits the calculated salt intake data to the cloud management platform in real time, and the cloud management platform securely stores and classifies the data. The query client can be a mobile phone, computer or other device. Patients, family members or medical staff can query the salt intake data from the cloud management platform at any time through the query client to understand the patient's diet.

[0068] The device can realize real-time monitoring of salt intake. No matter where patients and medical staff are, as long as there is a network connection, they can query the client to understand the patient's salt intake at any time, identify problems in time and take corresponding measures.

[0069] The cloud management platform can store a large amount of salt intake data, analyze and compile statistics on the data, and provide a basis for doctors to formulate personalized treatment plans. At the same time, the long-term storage of data also facilitates the tracking and evaluation of patients' diets.

[0070] Example 4

[0071] A salt intake monitoring device for a heart failure patient, comprising a salt tank shell, a salt tank, a salt spoon, a control module, a first weighing sensor, a base, a connecting rod, a cylinder, a second weighing sensor and a baffle;

[0072] The salt tank is installed at the upper end of the salt tank shell, and the first weighing sensor is installed at the lower end; a base is installed on the top surface of the first weighing sensor; a second weighing sensor is installed on the outer middle part of the salt tank; the head of the salt spoon is placed on the base, and the tail end extends to the outside of the salt tank shell; the cylinder is installed in the middle part of the salt tank shell; the connecting rod is horizontally arranged, one end of which is connected to the output end of the cylinder, and the other end is connected to the salt spoon; the control module is installed at the bottom of the salt tank shell.

[0073] The working principle of this embodiment:

[0074] The salt tank is firmly mounted on the upper inner end of the salt tank shell. The first weighing sensor at the lower inner end of the salt tank shell measures the weight of the salt tank by sensing the pressure exerted on it by the salt tank. The second weighing sensor on the outer middle of the salt tank is specifically used to measure the weight of the salt spoon. The head of the salt spoon is placed on the base to ensure that the salt spoon is in a stable position when not in use. Its tail extends to the outside of the salt tank shell to facilitate the patient to take salt. The cylinder is installed in the middle of the inner part of the salt tank shell. When salt needs to be taken, the control module issues a command, and the cylinder starts working, pushing the salt spoon through the connecting rod to perform the salt taking operation. The control module, as the core control part of the entire device, is installed at the bottom of the salt tank shell and is responsible for coordinating the work of various components to ensure the normal operation of the device.

[0075] Example 5

[0076] The difference between this embodiment and embodiment 4 is that a push rod is arranged in the middle of the head of the salt spoon; the push rod is arranged vertically, with the lower end connected to the head of the salt spoon and the upper end extending upward.

[0077] A push rod is added in the middle of the head of the salt spoon. The push rod is set vertically, with the lower end firmly connected to the head of the salt spoon and the upper end extending upward. During the salt taking process, the push rod can play a role of auxiliary support and positioning, making the salt spoon more stable when taking salt, and also making it easier for patients to accurately control the amount of salt taken.

[0078] The working principle of this embodiment is the same as that of Embodiment 4.

[0079] Example 6

[0080] This embodiment differs from Embodiment 5 in that it further comprises a sealing cover and a sealing rubber ring; a sealing rubber ring is arranged on the outer side of the upper end of the salt tank shell; and the sealing cover is installed on the top surface of the salt tank shell.

[0081] On this basis, a sealing cover and a sealing rubber ring are added. The sealing rubber ring is installed on the outer side of the upper end of the salt tank shell, which can effectively prevent air and moisture from entering the salt tank shell and keep the inside of the salt tank dry. The sealing cover is installed on the top surface of the salt tank shell. When the salt is not in use, the sealing cover can tightly cover the salt tank to prevent the salt from being contaminated by dust, debris, etc.

[0082] The working principle of this embodiment is the same as that of Embodiment 4.

[0083] Example 7

[0084] The difference between this embodiment and embodiment 6 is that a magnetic block is provided at the front end of the head of the salt spoon; and a magnet is provided at one end of the connecting rod connected to the salt spoon.

[0085] A magnetic block is set at the front end of the salt spoon head, and a magnet is set at the end of the connecting rod connected to the salt spoon. When the connecting rod is close to the salt spoon, the magnet and the magnetic block attract each other, so that the salt spoon and the connecting rod are firmly connected. When the cylinder pushes the salt spoon through the connecting rod to take salt, this connection method can ensure that the salt spoon will not fall off accidentally, ensuring the stability of the salt taking process.

[0086] The working principle of this embodiment is the same as that of Embodiment 4.

[0087] Example 8

[0088] This embodiment differs from Embodiment 7 in that it further comprises a control button; the control button is arranged on the outer side of the middle part of the salt tank shell.

[0089] The working principle of this embodiment is the same as that of Embodiment 4.

[0090] In summary, the present invention has the following beneficial effects:
