Description

Novel implantable biosensor implanter

The technical field is as follows:

the utility model relates to an implantation nature biosensor field especially relates to a novel implantation nature biosensor implants ware.

Background art:

many diseases require monitoring of physiological parameters such as body temperature, heart rate, blood pressure, blood oxygen, blood sugar, etc. at any time. Some parameters can be directly measured by physical methods, such as temperature and heart rate, and can be measured in vitro at any time. However, some parameters cannot be obtained from in vitro measurements, such as the need for monitoring blood glucose is one example of a condition that is prominent in diabetics who must obtain from measuring blood or interstitial fluid. The method for measuring the tissue fluid is a continuous monitoring means which can be used in reality, has the advantages that continuous blood sampling or the implantation of a sensor fixing device into a blood vessel are not needed, the method can be used as an apparatus carried by a daily patient, the high risks such as infection or blood loss are not introduced, the necessary data can be effectively provided, and the method becomes an important direction for the development of clinical monitoring.

Taking blood sugar detection as an example, with the significant increase of incidence rate of diabetes in recent years in the world, blood sugar monitoring has become an increasingly indispensable clinical means, and products for patient self-testing blood sugar are mainly single measurement of peripheral blood sugar (fingertip blood), but for type I diabetes patients or type II diabetes patients using insulin therapy, individual single measurement often fails to meet the requirement of blood sugar control. There is a need for a method that provides continuous blood glucose monitoring so that a patient can know his/her blood glucose status at any time and take timely measures to most effectively control the condition of an illness, prevent complications, and achieve a high quality of life.
