BIOCHEMICAL ANALYSIS CARTRIDGE HAVING IMPROVED OPERABILITY

摘要

The present invention relates to a biochemical analysis cartridge having improved operability. More particularly, the present invention provides a biochemical analysis cartridge including an insertion-type sample cartridge and a reaction cartridge receiving the insertion-type sample cartridge, in which,as the sample cartridge is inserted into the reaction cartridge,a reaction solution chamber moves toward a broken part of a covertape so as to automatically supply the reaction solution stored in the chamber. The biochemical analysis cartridge having improved operability according to the present invention can induce the mixing between a sample and a reaction solution by simply inserting them into the reaction cartridge and a reaction thereafter, thereby minimizing the process of a measurer to intervene in the assay, and subsequently improving user convenience and operability.

主权项

1. A biochemical analysis cartridge comprising an insertion-type sample cartridge for supplying a sample and a reaction cartridge receiving the insertion-type sample cartridge, wherein
the reaction cartridge includes: a receiving unit into which the insertion-type sample cartridge is inserted to be received; a chamber for storing a reaction solution, provided inside the receiving unit with an opening at one end, including a covertape attached to the opening to prevent the discharge of the stored reaction solution, and provided such that the opening to which the covertape is attached faces the inside of the reaction cartridge; a covertape breaking unit provided to oppose the covertape of the chamber for storing the reaction solution and provided to be distant from the covertape; a chamber moving frame fixing the chamber for storing the reaction solution and including a moving path through which the chamber for storing the reaction solution moves toward the covertape breaking unit; and a mixing unit receiving the discharged reaction solution when the covertape is removed and mixing the reaction solution and a discharged bio-sample by contacting the reaction solution with a sample inlet of the insertion-type sample cartridge to form a mixed solution; a sample introduction unit where the sample is fixed to react with the mixed solution of the mixing unit; a measurement unit optically measuring a result of the reaction; and a flow path through which the mixing unit, the sample introduction unit, and the measurement unit are connected; and the insertion-type sample cartridge includes: a capillary-type sample injection unit for collecting and storing a liquid phase bio-sample which has a sample inlet for supplying the stored bio-sample to the reaction cartridge; and a protrusion which contacts the chamber for storing a reaction solution of the reaction cartridge to move the chamber for storing a reaction solution to the covertape breaking unit when the insertion-type sample cartridge is inserted into the receiving unit.
