Problems solved by technology

The blood gas biochemical test card generally introduces the test liquid through the liquid pipeline, and opens or closes the liquid pipeline by setting an on-off switch rubber plug on the main body of the test card. In order to prevent liquid leakage, a sealing film is generally glued on the main body of the test card for Covering the channel switch rubber plug, the sealing film is prone to air leakage caused by poor bonding, and because the channel switch rubber plug protrudes from the surface of the main body of the test card, a large cavity needs to be reserved at the arched position of the sealing film, and the test liquid cannot If the cavity is completely filled, it is easy to leave air bubbles in the cavity, and the air bubbles are easy to exchange gas with the test liquid, which is easy to affect the test results

Abstract

The invention relates to a blood gas analyzer and a blood gas biochemical test card thereof. The blood gas biochemical test card at least comprises an abutting and pressing element, a test card main body, a liquid pipeline and an elastic element, wherein the liquid pipeline is arranged on the test card main body; the elastic element is connected with the test card main body and seals the liquid pipeline; a groove is formed in the surface, opposite to the elastic element, of the liquid pipeline; the elastic element is positioned between the groove and the abutting and pressing element; the abutting and pressing element is provided with a press head matched with the shape of the groove. The groove is formed in the liquid pipeline and forms a whole with the liquid pipeline; no excessive cavity is formed; no bubble is remained; meanwhile, the test liquid consumption is reduced; the test accuracy is improved; the arrangement of an on-off switch rubber plug and a sealing film used for covering a passage switch rubber plug on the test card main body is not needed; the air leakage problem is avoided; the part number is reduced; the production is convenient; the product rejection rate is reduced.

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. The blood gas biochemical test card generally introduces the test liquid through the liquid pipeline, and opens or closes the liquid pipeline by setting an on-off switch rubber plug on the main body of the test card. In order to prevent liquid leakage, a sealing film is generally glued on the main body of the test card for Covering the channel switch rubber plug, the sealing film is prone to air leakage caused by poor bonding, and because the channel switch rubber plug protrudes from the surface of the main body of the test card, a large cavity needs to be reserved ...
