Description

Technical Field

[0001] The present application relates to the technical field of blood glucose monitoring, and in particular to an optical fiber signal transmission device for blood glucose monitoring. Background Art

[0002] Blood sugar monitoring is a regular check of blood sugar levels. Blood sugar monitoring can better control the changes in blood sugar in diabetic patients, and has important guiding significance for exercise, diet, and rational use of drugs, and can help patients find problems at any time. Blood sugar monitoring time points are generally divided into fasting monitoring and post-meal monitoring. Post-meal monitoring is generally recommended to be done 2 hours after a meal, while fasting monitoring is called fasting blood sugar as long as there is no energy intake for 8-10 hours. The frequency of blood sugar monitoring has different requirements. For people with stable blood sugar control, it is recommended to monitor blood sugar once a day or every other day. If blood sugar control is not stable, or blood sugar is relatively high, and there are patients who often have hypoglycemia, it is recommended that blood sugar be monitored more frequently. In order to better control blood sugar in hospitalized patients, the frequency of blood sugar monitoring is often 7 times a day, that is, a total of 6 times before and after three meals, plus blood sugar before bedtime or at night and early morning. It can better grasp the patient's blood sugar fluctuations so that doctors can adjust the blood sugar-lowering plan in time. Patients at home are not recommended to monitor so frequently, which has a greater impact on the patient's quality of life. You can consider monitoring once a day, such as monitoring fasting on Monday, monitoring after breakfast on Tuesday, monitoring after lunch on Wednesday, and monitoring after dinner on Thursday, so that the blood sugar level of each meal can be taken into account.

[0003] Fiber optic transmission refers to the transmission of data and signals using optical fibers as the medium. Optical fibers can not only be used to transmit analog and digital signals, but can also meet the needs of video transmission. Fiber optic transmission generally uses optical cables, and without the use of repeaters, the transmission distance can reach tens of kilometers.

[0004] Current blood glucose monitors generally use wired or wireless transmission, which can achieve the purpose of data transmission, but the data transmission efficiency is low, the anti-interference performance is poor, and the background monitoring data is inaccurate. Therefore, it is necessary to design a fiber optic signal transmission device for blood glucose monitoring. Summary of the invention
