Title: BLOOD GAS ANALYZER AND BLOOD GAS BIOCHEMICAL TEST CARD THEREOF
Abstract:
A blood gas analyzer and a blood gas biochemical test card thereof, at least comprising: a test card body (10) provided with a sample intake port (110), a gas suction port (120) and a liquid pipe (130); and an electrode circuit board (20) provided on the test card body (10). The liquid pipe (130) comprises a waste chamber (133), a test liquid pipe (131) with one end in communication with the sample intake port (110), an electrode pipe (134) with two ends in communication with the waste chamber (133) and a test liquid pipe (131) respectively. The electrode pipe (134) is connected to the electrode circuit board (20). The waste chamber (133) at least comprises: a first waste chamber (1334) and a second waste chamber (1335) arranged side by side, and a liquid discharge port (1333) in communication with the first waste chamber (1334) and the second waste chamber (1335). The first waste chamber (1334) is provided with a liquid inlet (1331) in communication with the electrode pipe (134). The second waste chamber (1335) is provided with a liquid outlet (1332) in communication with the gas suction port (120). The liquid outlet (1332) is located above the liquid inlet (1331), and the liquid discharge port (1333) is located on one side of the liquid outlet (1332). There is no need to provide a sealing plug on the gas suction port (120), and an external device is in direct communication with the gas suction port (120). The problem of debris being generated due to puncturing the sealing plug is not present, and the hidden danger of failing a test due to an electrode being contaminated by debris is eliminated.
