Problems solved by technology

However, during the test, the sampling needle of the reagent package 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 to the test card with the calibration solution. On the test electrode, the electrode cannot be te

Abstract

The invention relates to a blood-gas analyzer and a blood-gas biochemical test card. The blood-gas analyzer at least comprises a test card main body, a liquid pipeline and an electrode circuit board, wherein the test board main body is provided with a sample inlet and an extraction opening, the liquid pipeline and the electrode circuit board are arranged on the test card main body, the liquid pipeline comprises a test liquid pipeline, a calibration liquid pipeline, a waste liquid cavity and an electrode pipeline which are communicated mutually, the electrode pipeline is connected with the electrode circuit board, one end of the test liquid pipeline is communicated with the sample inlet, a calibration liquid opening is formed in one end of the calibration liquid pipeline, and the highest liquid level position of the calibration liquid pipeline is higher than the liquid level of test liquid. The blood-gas analyzer has the advantages that the calibration liquid opening requires no sealing plug and is directly communicated with an external device, so that the problem of scraps caused by piercing of the sealing plug is avoided, and the hidden danger of test scrapping resulting from pollution of the scraps to electrodes 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 calibration liquid flows out from the pipeline, and the calibration liquid port of the test card is generally sealed by a sealing plug. However, during the test, the sampling needle of the reagent package 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 to the test card with the calibration solution. On the te...
