Technical Field
[0001] The present invention relates to the technical field of biosensors, and in particular to an integrated implant component of an implantable biosensor. Background Art
[0002] For the diabetic population, traditional fingertip blood glucose meters have shortcomings such as being invasive, having limited information, and being unable to reflect blood glucose fluctuations and provide warnings. They can no longer meet the needs of some people, especially for type 1 diabetes patients who have real-time transmission requirements for blood glucose fluctuations and type 2 diabetes patients who require intensive insulin treatment.
[0003] Due to the need for continuous blood glucose monitoring, the integrated implant component and internal components of the implantable biosensor are required to implant the sensor into the subcutaneous tissue of the human body. Measuring the blood glucose concentration between tissue fluids is a continuous monitoring method that can be used in reality. Its single service life is one to two weeks, which greatly reduces the pain caused by the process of continuous fingertip blood sampling and venous blood sampling. Currently, such implant devices on the market have problems such as complex user operation, long implantation process, and easy mis-triggering of the push device, which leads to reduced user compliance (compliance, Patient compliance / Treatmentcompliance, also known as compliance, refers to the patient's behavior of taking treatment according to the doctor's prescription and consistent with the doctor's orders. It is customary to call the patient "cooperation"; otherwise it is called non-compliance) and experience.
[0004] The transmitter (device for transmitting monitored biological signals) has a compact structure and volume, which helps to improve the wearing experience. In the current integrated products, the transmitter is in working or silent state when placed inside the transmitter. However, no matter which of the above methods is used, the transmitter and sensor assembly have been electrically connected.

The needle member 4 and the fixing seat 7 drive the transmitter 10, the sensor assembly 12 and the auxiliary needle member 11 to move downward at the same time. The bottom surface of the transmitter 10 is bonded to the skin surface. The implantation needle 111 of the auxiliary needle member 11 implants the sensor electrode 121 of the sensor assembly 12 under the skin. The protruding bone position 622 of the main sliding seat 6 gradually moves to the upper part of the first sliding groove 713 and approaches the outer hanging arm 42 of the needle member 4.
