Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a portable nuclear-surface temperature difference meter used for measuring the prognosis of heart failure. Background Art

[0002] Heart failure is the terminal stage of all cardiovascular diseases, and its prognosis determines the prevention and control effects of all cardiovascular diseases. At present, although the treatment technology of heart failure has made some progress, its overall prognosis is still poor. Therefore, it is urgent to find a method that can accurately assess the severity and prognosis of heart failure so as to intervene early, prevent its deterioration and recurrence, and ultimately achieve the goal of improving prognosis and prolonging life. However, in the current clinical practice, there is still a lack of gold standard for the assessment of the severity and prognosis of heart failure.

[0003] At present, the evaluation method used in clinical practice is to include a series of predictive factors (such as left ventricular ejection fraction, New York heart function class, B-type natriuretic peptide / N-terminal B-type natriuretic peptide, blood sodium, blood oxygen, hematocrit, electrocardiogram QRS wave width, blood pressure, heart rate, renal function, traditional treatment effect, volume load, etc.) and combine them with clinical manifestations for comprehensive evaluation. However, the prediction effect of using any of the above predictive factors alone is not ideal, and even if multiple predictive factors are included at the same time, it is difficult to accurately evaluate the patient's prognosis. In addition, since most heart failure patients in my country are managed in community hospitals, for most community hospitals, even if the evaluation efficiency of the above predictive factors is not high, some of them are difficult to obtain. Utility Model Content

[0004] In order to solve the above problems existing in the existing heart failure prognosis determination and evaluation methods, the utility model designs a new portable nuclear-to-surface temperature difference instrument for heart failure prognosis determination.

[0005] The inventors have found in clinical practice that patients with severe heart failure will complain of unbearable heat in their chests, and therefore crave cold drinks (ice cream, popsicles, and even ice cubes), and to the point of "having to eat", and the mortality rate of such patients in the short term is extremely high. The inventors speculate that this is because the "power pump" function of the heart of patients with heart failure is reduced, breathing is accelerated, the amount of respiratory muscle exercise is increased, and the sympathetic nerves are excited, resulting in increased heat production. On the other hand, due to decreased cardiac function and sympathetic excitement, the skin blood flow is reduced, resulting in reduced heat dissipation. The final result is that the core temperature increases, the surface temperature decreases, and the core-surface temperature difference increases. Based on the above analysis, the core-surface temperature difference can be used as a quantitative indicator to reflect the clinical manifestation of craving for cold drinks, and this clinical manifestation is highly correlated with the prognosis of heart failure. Therefore, measuring the core-surface temperature difference can evaluate the severity and prognosis of heart failure.

[0006] The design scheme of the portable nuclear-surface temperature difference meter of the utility model includes: a core temperature measuring device is formed by installing an infrared non-contact temperature measuring probe in the earphone head, which is used to measure the core temperature (the tympanic membrane temperature is measured to represent the core temperature); a surface temperature measuring device is formed by installing an infrared non-contact temperature sensor on the inside of a bracelet, which is used to measure the surface temperature. The two are connected by Bluetooth, the earphone is the secondary Bluetooth, and the bracelet is the main Bluetooth. Among them, in addition to the temperature measurement function, the earphone also has the function of connecting to a mobile phone. An earphone compartment is provided inside the bracelet, and the screen is a compartment door that can be folded open, and a magnetic charging port is provided inside; after receiving the temperature from the earphone, the bracelet automatically calculates the core-surface temperature difference, and the measurement result is displayed on the bracelet screen and stored in the chip. In addition, the bracelet also has basic functions such as displaying time. Furthermore, after the bracelet is connected to the Bluetooth APP of the mobile phone, the measurement results can be uploaded to the server, and the server dynamically analyzes the measurement results, quantifies the opinions of experts, sets symptom evaluation standards, and provides diagnostic reports for reference by clinicians, and can also give patients reasonable suggestions.

[0073] The touch screen uses organic light-emitting diode OLED (Organic Light-Emitting Diode) display technology, which uses a very thin organic material coating and a glass substrate (or flexible organic substrate). When current passes through, these organic materials will emit light, so there is no need for a backlight, which can significantly reduce the power consumption of the device.

[0074] In summary, the portable nuclear-surface temperature difference instrument for heart failure prognosis determination of the utility model has the following advantages:

[0075] (1) The core-surface temperature difference of the human body can more accurately and comprehensively reflect the changes in the body's blood circulation state caused by changes in cardiac function in patients with heart failure, as well as the abnormal body heat distribution caused by such changes. It reflects the "pure effect" of the body's failure to transfer endogenous heat from the core to the peripheral parts and dissipate it, thereby remaining in the body. Therefore, it can better eliminate the individual differences in body temperature. The device of the utility model can synchronously measure the core temperature and surface temperature of the human body, and obtain the core-surface temperature difference of the human body in real time. The design of the utility model can more comprehensively reflect the temperature condition of the human body, provide doctors and users with more accurate health data, and accurately measure and evaluate the severity and prognosis of the patient's heart failure without incorporating many of the currently commonly used clinical predictive factors.

[0076] (2) The device of the utility model is suitable for all patients with heart failure. The more serious the condition of the patient, the higher the prediction accuracy. The development process of the disease can be accurately known based on the changing trend of the detection data.

[0077] (3) The device of the utility model has a simple structure and is easy to use, and is very suitable for use in community hospitals and patients at home, thereby extending clinical examinations outside the hospital, providing convenience for patients while reducing the medical pressure on general hospitals.

[0078] (4) The device of the utility model can synchronize data and remotely manage data with smart devices such as mobile phones through Bluetooth connection. Patients can view their health data through their mobile phones, and doctors can also understand the health status of patients by remotely accessing the data of the device so as to implement timely intervention, thus realizing intelligent health management.
