Belonging to medical diagnosis, especially the in vitro diagnosis field, the invention discloses a dry type biochemical immune mixed analysis system and a device thereof. The mixed analysis system includes a dry type biochemical and immune detection system able to individually or simultaneously complete biochemical and immune detection, and the system includes mixed type and parallel type two modes. The system device involved in the invention is combined by a support base plate, a reagent strip storage unit, a sample addition unit, a sample unit, a detection unit, and a circuit unit, and includes single reaction disk and double-reaction disk two forms. Specifically, the single reaction disk can complete biochemical and immune analysis mixedly, the double reaction disks correspond to biochemical and immune analysis procedures respectively, and the detection process of the two can be finished integratedly. According to the invention, between-sample pollution is effectively reduced, compared with single biochemical type or immune type, the system and the device greatly increase the number of detection items, and have the characteristics of fast detection speed and small blood collection amount, thus reducing the patient pain in the detection process.
