Problems solved by technology

[0006] The detection principles of blood gas analyzers in the prior art are generally similar, and most of them detect blood samples through the electrodes in the sensor module; however, in actual use, it is found that when different blood gas analyzers detect the same blood sample, There are large differences in the test results; when the same blood gas analyzer performs different tests on the same blood sample, there are still differences in the results, and the detection accuracy of existing testers still needs to be improved

Embodiment 1

[0078] Such as Figure 1-Figure 28 As shown, the present invention discloses a blood gas analysis instrument, see figure 1 , including a detection and analysis main board 1 for detecting and analyzing blood samples, and a bearing seat 2, on which a limiting chute 3 for making the test card 5 slide directionally;

[0079] The pressing assembly 8, the top heating limiting assembly 9, the bottom heating limiting assembly 7, the pushing assembly 10 and the driving assembly 6 arranged on the bearing seat 2; the pressing assembly 8 and the top heating limiting assembly 9 are located in the limiting chute 3, the bottom heating limiting assembly 7 and the pushing assembly 10 are located below the limiting chute 3; from top to bottom are the pressurizing assembly 8, the top heating limiting assembly 9, the pushing assembly 10 and the bottom heating limiting assembly 7 ;

[0080] The pressurizing assembly 8 is used to squeeze the gas storage area 531 provided by the test card 5;

[0...

Embodiment 2

[0170] This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, the worm wheel 603 includes a runner 610 and a fan-shaped protrusion arranged on the runner 610, the runner 610 is installed on the rotating shaft 605, and the fan-shaped The protruding portion is provided with worm gear teeth capable of meshing with the worm 604 . Since the runner 610 is provided with a fan-shaped protrusion, the fan-shaped protrusion is provided with worm gear teeth that can mesh with the worm 604; so that the runner 610 and the fan-shaped part 611 form an incomplete worm wheel 603, in actual In use, the installation space can be greatly saved.

Abstract

The invention discloses a blood gas analysis instrument which comprises a detection analysis main board for detecting and analyzing a blood sample and further comprises a bearing seat provided with a limiting sliding groove for enabling a test card to directionally slide, and a pressurizing assembly, a top heating limiting assembly, a bottom heating limiting assembly, a pushing assembly and a driving assembly arranged on the bearing seat. The pressurizing assembly and the top heating limiting assembly are located above the limiting sliding groove, and the bottom heating limiting assembly and the pushing assembly are located below the limiting sliding groove; the pressurizing assembly, the top heating limiting assembly, the pushing assembly and the bottom heating limiting assembly are sequentially arranged from top to bottom; the pressurizing assembly is used for extruding a gas storage area of the test card; the top heating limiting assembly is used for limiting and heating the top of the test card; and the bottom heating limiting assembly is used for limiting and heating the bottom of the test card. The blood gas analyzer is mainly used for detecting and analyzing a blood sample, and has the advantages of good detection effect and high accuracy.

Description

technical field [0001] The invention relates to the technical field of blood gas analysis, in particular to a blood gas analysis instrument. Background technique [0002] Blood gas analyzer is an instrument based on the principle of electrochemistry, which is used to quantitatively detect the acidity and alkalinity (pH), partial pressure of carbon dioxide (PCO2), partial pressure of oxygen (PO2), electrolytes and other related indicators in arterial whole blood samples. When the blood gas analyzer performs blood sample detection, the blood sample to be tested is generally injected into the test card, and then the test card is inserted into the blood gas analyzer, and the blood sample is detected through the electrodes in the sensor module. [0003] The application number is: CN201320881366.5, and the publication number is: CN203732536U discloses a blood gas analyzer, which includes a blood gas analyzer body, a test card and a reagent pack, wherein the test card and the blood...
