Background

The test card is widely applied to the medical industry, the test card is generally integrated with a biochemical test point and is commonly used for carrying out blood gas biochemical test, when in test, an external reagent pack is usually used for injecting a calibration liquid into a calibration pipeline of the test card for pre-calibration, then the test liquid is injected into a test pipeline of the test card, and the calibration pipeline is communicated with the test pipeline and is converged to a reaction pipeline for testing. In general, when pre-scaling is performed, the scaling pipeline needs to be isolated from the test pipeline, so as to avoid that the scaling liquid enters the test pipeline to influence the subsequent test liquid.

Specifically, the card body 2 is provided with a calibration line 21, a test line 22, a reaction line 23, and a groove 24, the calibration line 21 is in communication with the reaction line 23, the groove 24 is disposed between the calibration line 21 and the test line 22, and the reaction line 23 is used for performing a reaction test on a liquid to be tested. The on-off valve 3 is movably arranged in the recess 24, the on-off valve 3 being configured to block the calibration line 21 and the test line 22 when in the first position and to communicate the calibration line 21 with the test line 22 when in the second position. It will be appreciated that the sealing membrane 9 may block the calibration line 21, the test line 22, the reaction line 23 and the recess 24 on the card body 2, avoiding liquid leakage during testing.

In the present embodiment, the on-off valve 3 may be switched by manual pulling, or may be moved relative to the card body 2 by a link mechanism.

In some embodiments, as shown in fig. 4, the on-off valve 3 includes a rod 31 and a first sealing ring 32, the rod 31 is provided with a through groove 311, and the first sealing ring 32 is sleeved on the rod 31 and located at one side of the through groove 311. When the switch valve 3 is at the first position, the first sealing ring 32 seals the calibration pipeline 21 and the test pipeline 22, and when the switch valve 3 is at the second position, the passing groove 311 is communicated with the calibration pipeline 21 and the test pipeline 22. It will be appreciated that by measuring in advance the depth of the groove 24, the position of the connection between the test line 22 and the calibration line 21, the length of the rod 31, and the position of the first seal 32, the connection between the test line 22 and the calibration line 21 can be blocked by the first seal 32 when the on-off valve 3 extends into the groove 24 by a predetermined first length, and the connection between the calibration line 21 and the test line 22 when the on-off valve 3 extends into the groove 24 by a predetermined second length by the through groove 311.

Further, the on-off valve 3 further includes a second sealing ring 33, the second sealing ring 33 is sleeved on the rod body 31, the second sealing ring 33 is located at the other side of the passing groove 311, and the second sealing ring 33 is used for sealing off the groove 24. In this way, the outside can be prevented from entering the card body 2 through the groove 24, and the liquid to be tested can be prevented from leaking to the outside through the gap between the rod 31 and the groove 24.

In some embodiments, the switch valve 3 further includes a stopper 34 located outside the groove 24, the stopper 34 being connected with the rod body 31, and the card body 2 further includes a stopper lug 25 protruding from a side end of the card body 2; the stopper 34 abuts against the stopper lug 25 when the on-off valve 3 is in the first position, and the stopper 34 abuts against the sidewall edge of the groove 24 when the on-off valve 3 is in the second position. In this way, when the joint of the calibration pipeline 21 and the test pipeline 22 needs to be blocked, the limiting block 34 is only required to be pushed to be abutted against the limiting lug 25, and when the calibration pipeline 21 is required to be communicated with the test pipeline 22, the limiting block 34 is only required to be pushed to be abutted against the side wall edge of the groove 24, so that the operation is convenient.

The sealing film 9 also shields the waste liquid line 27, the waste liquid tank 26, and the negative pressure line 28.

It will be appreciated that the calibration solution after reaction in the reaction pipeline 23 needs to be pumped to the waste liquid tank 26 under the negative pressure environment to open the switch valve 3, the solution to be tested in the external sample injection container is sucked into the test pipeline 22 under the negative pressure, moves towards the reaction pipeline 23 under the negative pressure, and flows towards the waste liquid tank 26 after the reaction in the reaction pipeline 23. It is to be noted that the connection of the waste liquid channel 27 to the waste liquid channel 26 is provided at a position where the waste liquid channel 26 is distant from the reaction channel 23, which is advantageous in preventing the flow of waste liquid from the waste liquid channel 26 to the waste liquid channel 27 when the test card 1 is placed vertically.
