Blood gas analyzer and blood gas biochemical test card

Abstract

The invention relates to a blood gas analyzer and a blood gas biochemical test card. The blood gas biochemical test card at least includes a test card main body equipped with a sample introduction port, an air extraction port and a liquid pipeline, and an electrode circuit board arranged on the test card main body; the liquid pipeline includes a waste liquid chamber, a test liquid pipeline having one end communicating with the sample introduction port, and an electrode pipeline having two ends respectively communicating with the waste liquid chamber and the test liquid pipeline; the electrode pipeline is connected with the electrode circuit board; the waste liquid chamber at least includes a first waste liquid chamber and a second waste liquid chamber arranged side by side, and a liquid discharge port communicating with the first waste liquid chamber and the second waste liquid chamber; the first waste liquid chamber is equipped with a liquid inlet communicating with the electrode pipeline; the second waste liquid chamber is equipped with a liquid outlet communicating with the air extraction port; the liquid outlet is located above the liquid inlet; the liquid discharge port is located at one side close to the liquid outlet. The air extraction port has no need of arrangement of a seal plug, an external device directly communicates with the air extraction port, the problem of debris generation due to piercing of the sealing plug does not exist, and the hidden danger of test scrapping caused because debris pollutes an electrode is eliminated.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a blood gas analyzer and a blood gas biochemical test card. Background technique [0002] The blood gas biochemical test card is widely used in the medical industry. The test card integrates biochemical test electrodes, calibrates through the calibration solution in the reagent pack, and then tests the test solution. After the test is completed, in order to prevent the calibration solution and test solution from The air flows out from the air extraction port, and the air extraction port of the test card is generally sealed by a sealing plug. However, during the test, the sampling needle on the vacuum pump in the instrument needs to pierce the sealing plug to communicate with the pipeline in the test card. During the piercing process, the sealing plug is prone to generate debris, and the debris is easy to flow with the calibration solution. On the test electrode, the electrode c...

However, during the test, the sampling needle on the vacuum pump in the instrument needs to pierce the sealing plug to communicate with the pipeline in the test card. During the piercing process, the sealing plug is prone to generate debris, and the debris is easy to flow with the calibration solution. On the test electrode, the electrode cannot be tested and the test card is scrapped; and after the test card test is completed, the sampling needle needs to be separated from the sealing plug, because the sealing plug has been pierced and there is a puncture hole, so the sealing plug cannot completely seal the puncture hole. The test liquid flows out from the piercing hole, causing a hidden danger of liquid contamination
