Biochemical item detection disc

A biochemical item detection disc, comprising:

• a disc (1), a first detection unit (2) and a second detection unit (3), wherein the first detection unit (2) and the second detection unit (3) are arranged on the disc (1);
• the first detection unit (2) comprises a centrifugal bag placing tank (21), a first diluent dosing tank (22), a sample adding tank (23), a first sample dosing tank (24), a first mixing tank (25), a first liquid separation tank (26) and first detection holes (27), wherein the centrifugal bag placing tank (21) is communicated with the first diluent dosing tank (22) through a liquid inlet flow channel;
• the sample adding tank (23) is communicated with the first sample dosing tank (24) through a flow channel;
• the first diluent dosing tank (24) is communicated with the first mixing tank (25) through a first siphon flow channel (4);
• the first sample dosing tank (24) is communicated with the first mixing tank (25) through a second siphon flow channel (5);
• and the first mixing tank (25) is communicated with the first liquid separation tank (26) through a third siphon flow channel (6);
• a plurality of the first detection holes (27) are arranged;
• and the first liquid separation tank (26) is communicated with the first detection holes (27) through the flow channel;
• the second detection unit (3) comprises a first diluent overflow tank (31), a second diluent dosing tank (32), a second sample dosing tank (33), a second mixing tank (34), a second liquid separation tank (35) and second detection holes (36), wherein the first diluent overflow tank (31) is communicated with the first diluent dosing tank (24) through an overflow channel;
• the first diluent overflow tank (31) is communicated with the second diluent dosing tank (32) through the liquid inlet flow channel;
• the second sample dosing tank (33) is communicated with the first sample dosing tank (24) through the flow channel;
• the second diluent dosing tank (32) is communicated with the second mixing tank (34) through a fourth siphon flow channel (7);
• the second sample dosing tank (33) is communicated with the second mixing tank (34) through a fifth siphon flow channel (8);
• and the second mixing tank (34) is communicated with the second liquid separation tank (35) through a sixth siphon flow channel (9);
• and
• a plurality of the second detection holes (36) are arranged;
• and the second liquid separation tank (35) is communicated with the second detection holes (36) through the flow channel.
