Abstract
Embodiments of the disclosure describe a structure for mounting a biosensor in a microfluidic cartridge including a biosensor holder, a gasket seal, a strut, and a leaf spring using a method for maintaining constant pressure and a microfluidic cartridge including the same. The structure allows pressure to be evenly distributed to the biosensor in order to secure reproducibility and reliability of the detection signal, and enables integrated configuration of the cartridge by using a minimum amount of space.
Claims19
A system for mounting a biosensor in a microfluidic cartridge, the structure comprising:
- a holder for holding a biosensor;
- a gasket seal for preventing leakage of fluid, the gasket seal in contact with the biosensor when present in the holder;
- a strut for evenly distributing pressure across a surface of the biosensor when present in the holder;
- and
- a leaf spring for applying pressure to the strut in a direction perpendicular to a surface of the strut, wherein the leaf spring is deformed against a wall of the holder.
