1. A cartridge for a sensor and for detecting one or more components in a sample comprising:
a lower board, an upper board, an adhesive layer in between the two boards, and a microfluidic channel, wherein the microfluidic channel is formed in between the boards and the adhesive and connects an inlet (1), a sample chamber (2), a detecting part (3), and a disposal chamber (4) in that order wherein, the lower board comprises the inlet (1) through which a sample is injected; the sample chamber (2) to store the sample temporarily; the detecting part (3) to detect one or more components in the sample; the disposal chamber (4) to get rid of the sample; an air pump chamber (6) connected to the sample chamber (2) by an air channel (14) to transfer the sample temporarily stored in the sample chamber (2) to the disposal chamber (4) via the microfluidic channel (5); a reagent pump chamber (7) configured to house a pouch (13) to keep a reagent therein and transfer the reagent to the disposal chamber (4) via the detecting part (3), wherein the reagent pump chamber (7) comprises a pouch crushing pin, wherein the reagent pump chamber (7) is connected by the reagent channel (15) to the microfluidic channel (5) between the sample chamber (2) and the detecting part (3), and the upper board comprises a vent hole (8) which lies above the disposal chamber (4); pores (9) which lie above the air pump chamber (6) and the reagent pump chamber (7); and a reading part (10) connected to a reading apparatus to detect a signal from the cartridge and stationed above the detecting part (3), wherein the lower board further comprises rubber stoppers (11) to seal the air pump chamber (6) and the reagent pump chamber (7) respectively, thereby functioning as an air pump and a reagent pump respectively, wherein the adhesive layer comprises pores just below and corresponding to the pores (9) of the upper board, the pores of the adhesive layer and the upper board reserving room for the rubber stopper (11). |
