INSERTION DEVICE FOR A BIOSENSOR

An implant device for a biosensor comprises a housing unit, an implant module, a bottom seat and a sensor component. The implant module is disposed in an accommodating space of the housing unit. The implant module includes a main body unit, a guiding set, an implant seat, a first elastic member, a needle withdrawal seat, a second elastic member, and a needle implant member. When the housing unit is pressed downwardly, the implant seat is displaced downwardly to perform automatic needle implantation by virtue of an resilient force of the first elastic member; when the needle implantation is completed, a limiting relationship of the implant seat and the needle withdrawal seat is released, so the needle withdrawal seat completes automatic needle withdrawal by releasing a resilient force of the second elastic member. The implant seat and the needle withdrawal seat are guided by the guiding set to move stably, thereby achieving easy control of production tolerances, increasing production speed and yield rate, improving the stability of needle implantation, and making needle implantation more painless and sensationless.
