Description

[Technical field]

[0001] The utility model relates to the technical field of blood sugar monitoring equipment, in particular to the technical field of low-power consumption multi-connection continuous glucose monitoring systems. [Background technology]

[0002] Diabetes is one of the most common chronic diseases in daily life. For patients with type 1 diabetes and some patients with type 2 diabetes, they need to rely on regular insulin injections every day to control the glucose (blood sugar) concentration in their blood, and the amount of each insulin injection depends on the blood sugar concentration test of the day.

[0003] There are three types of blood glucose meters commonly used in the market, namely blood glucose meters based on dry POC small instruments, biochemical meters based on wet reaction reagents, and continuous glucose monitoring (CGM). Among them, blood glucose meters based on dry POC small instruments can only detect the patient's blood glucose value at a single or multiple limited time points, and cannot continuously monitor blood glucose concentration; blood biochemical tests require drawing a large amount of venous blood, which can only be performed in professional medical institutions, and the results cannot be obtained in time; CGM can puncture the monitoring probe into the subcutaneous tissue and can continuously provide blood glucose information throughout the day.

[0004] At present, more and more hospitals choose to use CGM to continuously monitor blood glucose for in-hospital patients. The communication methods of CGM usually include ZigBee communication, traditional Bluetooth communication (such as Sinocare, Yuyue, Silicone and Jiunuo) and NFC communication (such as Abbott). However, the above communication methods are all one-to-one communication, and there are usually multiple patients in the inpatient department, which means that medical staff need to go to different wards one by one and interact with each CGM separately to obtain relevant data, which is very inconvenient. In addition, the shortcomings of ZigBee communication include 1) speed and reliability may be affected by interference and obstacles; 2) it is vulnerable to security threats (such as hackers can easily intercept and steal sensitive information transmitted wirelessly); 3) radio frequency technology will generate more electromagnetic radiation (although this radiation is generally considered to have no direct impact on human health, there are still many patients who are cautious about it). The traditional Bluetooth communication method has the problem of high power consumption because it requires devices to be connected before data transmission. The shortcomings of NFC communication method also include 1) it is easy to be attacked by hackers or viruses, which may lead to the leakage of personal information; 2) not all devices support NFC technology. If the device used does not support NFC technology, NFC cannot be used for data transmission, and the NFC transmission distance is short (only 5 to 10 cm). [Utility Model Content]

[0005] The purpose of the utility model is to solve the problems in the prior art and to propose a low-power multi-connection continuous glucose monitoring system that can achieve one-to-many transmission with low energy consumption.

[0006] To achieve the above objectives, the utility model proposes a low-power multi-connection continuous glucose monitoring system, including a collector, a Bluetooth gateway and an electronic terminal. Several collectors transmit data with the Bluetooth gateway and / or the electronic terminal respectively through Bluetooth broadcasting.

[0007] Preferably, one Bluetooth gateway is provided for every 2 to 50 collectors.

[0008] Preferably, the electronic terminal is a smart phone, a tablet computer or a PC.

[0009] Preferably, the electronic terminal stores the received blood glucose data in an internal memory and / or a cloud platform.

[0010] Preferably, the collector includes a casing, a patch, a sensor, a collector circuit board and a power supply. The patch is fixed to the outer wall of the casing, and the sensor, collector circuit board and power supply are respectively installed in the casing. The sensor has a sensor needle that can be implanted in the human body, and the collector can collect bioelectric current.

[0011] Preferably, the patch includes a base fabric layer and a release paper, one side of the base fabric layer is fixed to the housing and the other side is coated with glue and adhered with a release paper, and the release paper is torn off.

[0012] Preferably, a plurality of grooves are provided on the side of the base fabric layer carrying the glue.

[0013] Preferably, a plurality of indicator lights are provided on the outer wall of the casing.

[0014] Beneficial effects of the utility model:

[0015] 1) By combining the collector, Bluetooth gateway and electronic terminal to form a glucose monitoring system, multiple collectors can first transmit data to the Bluetooth gateway, and then use the Bluetooth gateway to transmit the data to the electronic terminal or server, thereby realizing one-to-many transmission, so that medical staff can monitor all patients wearing collectors in the entire ward only in the background, and a single collector can directly transmit data to the electronic terminal, thereby realizing one-to-one transmission;

[0016] 2) By using Bluetooth broadcasting to transmit data, power consumption can be effectively reduced (the traditional Bluetooth communication method usually enables two devices to transmit data to each other through Bluetooth connection, with a power consumption of about 8 to 12 mA, while the average power consumption of the Bluetooth broadcasting data transmission method is only about 40 to 50 uA), which can extend the use time of the collector;

[0017] 3) By using a base fabric layer and a release paper to form a patch together, and providing a plurality of grooves on the side of the base fabric layer facing the release paper and coating the adhesive, the grooves can be used to effectively increase the loading amount of the adhesive and the adhesion area between the base fabric layer and the skin, thereby improving the adhesion stability of the collector;

[0018] 4) By adding several indicator lights on the outer wall of the housing, medical staff can directly judge whether the collector is low on power by the color of the light during rounds, thereby further ensuring the normal operation of the collector.

[0019] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

After the collector is installed, the collector will first apply a certain voltage to the sensor to make the sensor generate a weak current in the subcutaneous tissue of the human body, then read the current and transmit the data to the Bluetooth gateway through Bluetooth broadcast. Then, the Bluetooth gateway sends the current data to the electronic terminal or server via wifi or local area network. Finally, the electronic terminal or server converts the current data into blood sugar values. At this time, medical staff can directly view the data detected by each collector through the electronic terminal.
