Continuous blood glucose monitoring system implanter with probe protection functionTechnical Field
The invention relates to the technical field of continuous blood glucose monitoring, in particular to a continuous blood glucose monitoring system implanter with a probe protection function.
Background
The continuous blood glucose monitoring system is a novel continuous dynamic blood glucose monitoring system which is put into clinical use in recent years, and is approved by the FDA in the United states in 2000. The core of the system is a probe and a blood glucose recorder. The blood sugar recorder is an electronic device which is of a pager size and convenient to carry, and the probe is a small and flexible platinum probe. The patient wears the device under daily living conditions, and the continuous dynamic blood glucose monitoring system detects and records blood glucose data. The continuous blood sugar monitoring system automatically records the blood sugar value once every few minutes, and records 200-500 blood sugar values all the day, so as to form continuous dynamic change data of blood sugar. Through data processing, medical professionals can know the blood sugar change condition of a patient in wearing equipment, wherein the blood sugar change condition comprises the highest blood sugar value, the lowest blood sugar value, the time and proportion of the blood sugar exceeding or falling below the set blood sugar value, the blood sugar change range before and after three meals, the blood sugar value of any determined time and the like, an accurate daily blood sugar change curve can be drawn, and marks of events such as exercise, diet and the like are marked on the curve, namely, a complete, detailed and comprehensive blood sugar map is drawn. Through the blood glucose map, doctors can find out a plurality of problems which cannot be found by the conventional blood glucose monitoring method, thereby providing important clues for timely clinical diagnosis and reasonable treatment. The results of continuous blood glucose monitoring can be used to reflect the results of diet control, exercise therapy and medication, and to guide the adjustment of the treatment regimen to improve the treatment condition; continuous blood glucose monitoring can reduce the risk of diabetic complications; good glycemic control can also improve the quality of life of the patient and improve the physical condition.
The current continuous blood glucose monitoring mainly comprises a probe and a blood glucose recorder, the probe is required to be implanted into the skin of a human body in a minimally invasive mode, the existing implantation mode is not directly implanted through the implanter, the implantation mode is assisted by taking one implanter as an auxiliary device, and the following problems exist in the process from the process of taking the probe out of a package to the process of implanting the probe into the skin of the human body in the existing two modes: 1) The probe is exposed to the air, and no protective measures are provided, so that the pollution of the probe is easy to occur, thereby influencing the accuracy of blood glucose monitoring data of continuous blood glucose; 2) The probe is implanted into a human body after being polluted, and the patient is at risk of cross infection; 3) The patient is easy to be injured by the probe of the probe in the implantation process; 4) The patient generates fear after seeing the probe; 5) The ejection force of the ejection mechanism of the implanter is too small to be implanted accurately, and patients have great pain in the process of implanting with too large ejection force;
there is no continuous blood glucose monitoring system implanter with probe protection function in the market at present.
