After the sensor electrode 210 and the needle assembly 240 are mounted on the lower case 232, the lower case 232 with the sensor electrode 210 and the needle assembly 240 is subjected to radiation sterilization, at which time the electronic component 250 is not damaged by the radiation sterilization because the electronic component 250 is not mounted.
For the post-sterilization stage, referring to fig. 3 and 5, the electronics 250 include a first portion 251 and a second portion 252, with sensor electronics at least partially located on the first portion 251, for example, the sensor electronics including a battery 253, a processor, conductive traces, and wireless communication circuitry. In one embodiment, the battery 253, processor, and wireless communication circuitry are located on the first portion 251, with portions of the conductive traces located on the first portion 251 and portions of the conductive traces located on the second portion 252.
When the electronic component 250 is mounted, the first part 251 is mounted on the upper surface of the lower case 232, the electrode signal input terminal is formed on the lower surface of the first part 251, when the first part 251 is mounted on the upper surface of the lower case 232, the electrode signal input terminal is electrically connected with the first conductive part 260, so that the subcutaneous glucose concentration information of the host 100 monitored by the sensor electrode 210 is transmitted to the first part 251 via the first conductive part 260 and the electrode signal input terminal,
after the first portion 251 is installed, the second portion 252 is installed in a stacked manner on the second portion 252. The battery 253 is mounted to the upper surface of the first portion 251 so as to be sandwiched by the first portion 251 and the second portion 252. The battery 253 is electrically connected to the electronic component 250 through a second conductive portion 270, wherein the second conductive portion 270 includes one second conductive member disposed on the upper surface of the first portion 251 and another second conductive member disposed on the lower surface of the second portion 252.

When the second portion 252 is mounted to the first portion 251, the two third conductive members abut each other. To this end, a complete electrical connection is made between the first portion 251 and the second portion 252, thereby forming a complete blood glucose signal transmission circuit between the sensor electrode 210, the first portion 251, and the second portion 252. The third conductive part 280 functions to support the first part 251 and the second part 252 in addition to the function of electrical connection, and the second part 252 can be made almost parallel to the first part 251 when laminated onto the first part 251 by the two third conductive members of the third conductive part 280 abutting against each other.
The second conductive component and the third conductive component are both made of conductive foam.
In other embodiments, for example, conductive rubber, conductive metal spring, conductive metal probe, etc. may be used instead of the conductive foam of the present invention.
To reduce the thickness of the body surface attachment unit 200 of the present invention, the first portion 251 and the second portion 252 of the electronic component 250 may employ, for example, flexible circuit boards.
After the second part 252 is installed, the upper shell 231 is installed on the lower shell 232, and at this time, the upper shell 231 and the lower shell 232 perform a pressing function on the first part 251 and the second part 252, since the electrical connection of the present invention uses an elastic conductive material, such as conductive foam, which is compressible, the conductive foam can be compressed by the pressing function of the upper shell 231 and the lower shell 232, thereby improving the stability and effectiveness of the electrical connection. Finally, the body surface attachment unit 200 is mounted in the cap 500.
