Description

TECHNICAL FIELD

[0001] The utility model relates to blood glucose monitoring technical field, concretely relates to an ear -wearing formula monitoring blood sugar ware. BACKGROUND

[0002] For diabetic patients, monitoring blood glucose can provide key data support for doctors to adjust treatment plans. For example, by monitoring fasting blood glucose and postprandial blood glucose, doctors can understand the efficacy of different hypoglycemic drugs (such as insulin, metformin, etc.). If it is found that the patient's blood glucose control is still not ideal after using a certain drug, the fasting blood glucose is continuously higher than 7mmol / L or the 2-hour postprandial blood glucose is higher than 10mmol / L, it is necessary to consider adjusting the drug dosage, replacing the drug or using other hypoglycemic drugs in combination. At the same time, blood glucose monitoring can also help doctors judge the patient's response to insulin therapy. The dose of insulin needs to be accurately adjusted according to the blood glucose level, because excessive insulin may cause hypoglycemia, and insufficient dose cannot effectively control blood glucose. By monitoring blood glucose, doctors can develop personalized insulin treatment plans for patients, including determining the type of insulin (short-acting, medium-acting, long-acting), injection time and dose.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor are within the scope of the utility model protection.

[0024] The following will combine the drawing, and the technical scheme provided by each embodiment of the utility model will be described in detail.

[0025] The utility model embodiment provides a kind of ear-mounted blood glucose monitor, including the hanging ear piece 1 for hanging in ear contour, the blood glucose monitoring equipment 2 for measuring blood glucose at personnel earlobe, the adjusting device 3 for converting the direction of blood glucose monitoring equipment 2 and the massage device 4 for personnel ear, the blood glucose monitoring equipment 2 includes infrared sensor 21, photoelectric blood volume sensor 22, battery and processor 23, the infrared sensor 21 and photoelectric blood volume sensor 22 are arranged on adjusting device 3, the processor 23 is arranged at the end of hanging ear piece 1, the battery is located inside processor 23, the infrared sensor 21, photoelectric blood volume sensor 22 and processor 23 are all by battery power supply, the processor 23 has Bluetooth connection function and can be connected with smart device by Bluetooth, alarm system 24 is equipped on the processor 23, the massage device 4 is arranged on processor 23;

[0026] The device can be worn on any one ear of the person, and the infrared sensor 21 emits preset wavelength near-infrared signals through the earlobe. After the blood and glucose in the capillary blood vessels in the earlobe absorb the corresponding excitation light, they are transmitted to the photoelectric blood volume sensor 22. The photoelectric blood volume sensor 22 collects the optical signal and converts it into an electrical signal to send to the processor 23. The processor 23 analyzes the received electrical signal to obtain the analysis results of blood pressure and blood glucose. The required data can be viewed through the Bluetooth connection device. After the blood glucose monitoring is completed, if the blood glucose is low, an alarm will be sounded to remind the person to supplement sugar food. If the blood glucose is high, an alarm will be sounded to remind the person to lower the blood glucose. The person can press the Xuanfeng acupoint behind the ear through the massage device 4 to lower the blood glucose.

[0027] The wearing method of the device can facilitate real-time monitoring of the person by the infrared sensor 21 and the photoelectric blood volume sensor 22.

[0028] The ear blood glucose sensor is usually equipped with a wireless communication module, such as Bluetooth or Wi-Fi technology. The blood glucose data measured by the sensor can be transmitted wirelessly to mobile devices such as smartphones and smartwatches. This wireless transmission method allows patients to view their blood glucose data at any time, and also facilitates remote management of data. For example, the patient's family members or medical personnel can view the patient's blood glucose records through a remote medical platform to discover abnormal blood glucose conditions and provide suggestions in a timely manner. Moreover, wireless data transmission can also achieve automatic data backup, avoiding data loss.

[0029] The interstitial fluid component under the skin of the ear is closely related to the blood glucose level. The sensor can penetrate the outermost stratum corneum of the ear skin and contact the interstitial fluid through a kind of ear-mounted blood glucose monitoring microneedle or painless contact mode. The biosensitive element in the sensor can react chemically with glucose in the interstitial fluid. For example, glucose oxidase is a commonly used biosensitive material that reacts with glucose to produce hydrogen peroxide and other products. Then, through electrochemical detection technology, the electrode is used to detect the change of these reaction products. When the glucose concentration increases, the amount of reaction product will also change accordingly, and the electrode will generate different electrical signals. These electrical signals can be processed by the signal conversion and amplification circuit in the sensor, and finally converted into blood glucose concentration values that can be read. The device uses the absorption and scattering characteristics of near-infrared light in the ear tissue to monitor blood glucose. The ear tissue has a specific absorption and scattering pattern for different wavelengths of near-infrared light, and the glucose molecule has a unique absorption peak in the near-infrared waveband. The sensor emits near-infrared light of a specific wavelength range to the ear skin. The light propagates in the tissue and interacts with the glucose molecules therein. Part of the light is absorbed by the glucose molecules, and the rest of the light is scattered or reflected back. The sensor detects the reflected or scattered light and analyzes its spectral characteristics. Through complex algorithms, information related to glucose concentration can be extracted from the changes in the light signal. For example, when blood glucose increases, the degree of light absorption at the glucose absorption peak wavelength will increase, and the sensor can calculate the blood glucose concentration according to this change.

[0037] In a further preferred embodiment of the present application, the processor 23 is internally provided with a GPS locator.

[0038] During the wearing of the device by the patient outdoors, when the patient faints due to low blood sugar, the GPS locator in the processor 23 can be used to know the location of the patient in the first time, so that timely positioning and rescue can be performed.
