Abstract

A highly integrated analyte detection device is provided. The transmitter is composed of a shell, a cover body, a circuit module and an electrical connection module. The circuit module is fixedly connected with the shell, one end of the electric connection module is fixedly connected with the circuit module, the other end extends to the outside through the through hole on the shell, and is electrically connected with other structural parts. The sealing material is filled between the electric connection module and the through hole, and the cover body and the shell are clamped together to form a seal for the circuit module, which makes the transmitter structure simpler. The shell and the circuit module can be processed separately and then assembled. The production process is less difficult and the production cost is reduced at the same time.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application is a 371 of international application of PCT application serial no. PCT/CN2021/105107, filed on Jul. 8, 2021, which claims the priority benefit of PCT application no. PCT/CN2020/102017, filed on Jul. 15, 2020. The entirety of each of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification. TECHNICAL FIELD The invention mainly relates to the field of medical devices, in particular to a highly integrated analyte detection device. BACKGROUND The pancreas in a normal human body can automatically monitor the level of glucose in the human blood and automatically secrete the required insulin/glucagon. In diabetics, the pancreas does not function properly and cannot produce the insulin the body needs. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function, and diabetes is a lifelong disease. At present, there is no cure for diabetes with medical technology. The occurrence and development of diabetes and its complications can only be controlled by stabilizing blood glucose. Diabetics need to have their blood glucose measured before they inject insulin into the body. At present, most of the testing methods can continuously measure blood glucose and send the data to a remote device in real time for the user to view. This method is called Continuous Glucose Monitoring (CGM). The method requires the device to be attached to the skin and the probe it carries is inserted into the tissue fluid beneath the skin. The transmitter of analyte detection device should not only form good waterproof and insulation protection for the circuit, but also make effective and reliable electrical connection between the circuit and the structural parts (such as sensors) outside the transmitter.
