Problems solved by technology

In this calibration method, the flow path is divided into gas path and liquid path, and the control of the gas-liquid intersection is more complicated. Especially in the case of a failure, the calibration liquid or cleaning liquid enters the gas path and easily damages the solenoid valve. In addition, Due to the existence of gas cylinders, the instrument is not convenient to be portable or hand-push, which makes the standard gas transportation inconvenient; because the standard gas is compressed gas, and the gas cylinder is large, it is not easy to transport and use, and the compressed gas has to go through It can only be used after decompression, heat preservation, and humidification, and the use process is relatively cumbersome

Embodiment 1

[0025] Example 1, see figure 1 , a blood gas analyzer, comprising: a needle valve 101 placed in a sampling rack 1, a sample case 2 connected to the needle valve 101, a first pump body 4 connected to the sample case 2, a first pump connected to the The waste liquid bag 7 of the body 4, the liquid detector 18 connecting the needle valve 101 and the second pump body 5, the fourth reagent bag 10 connected to the second pump body 5 through the second electromagnetic valve 9, and the fourth reagent bag 10 connected to the second pump body 5. The third solenoid valve 11 of the liquid detector 18, the first solenoid valve 8 connected to the second pump body 5, the first reagent bag 17 connected to the liquid detector 18 through the sixth solenoid valve 16, and the first reagent bag 17 connected to the liquid detector 18 through the fifth The solenoid valve 14 is connected to the second reagent bag 15 of the liquid detector 18, the third reagent bag 13 connected to the liquid detector ...

Embodiment 2

[0027] Example 2, see figure 2 , there is a main passage 102 in the needle valve 101, a first sampling port 105 and a second sampling port 106 are arranged on the main passage 102, the first sampling port 105 is connected to the first passage 103, and the second sampling port 106 is connected to the second sampling port 106. Channel 104; the first reagent, the second reagent, the protein-removing solution and the cleaning solution enter the main channel 102 in the needle valve 101 through the first channel 103, and enter the subsequent flow pipe 3 at the first sampling port 105 of the main channel 102; When cleaning the flow path, the cleaning liquid entering the main channel 102 is divided into two parts, one part enters the flow path pipe 3 from the first sampling port 105, cleans the sample box 2 and the subsequent flow path, and finally enters the waste liquid bag 7, and the other part enters the flow path pipe 3 from the first sampling port 105, and finally enters the was...

Embodiment 3

[0028] Example 3, see figure 1 with figure 2 , the first channel 103 is connected to the liquid detector 18, so that the first reagent, the second reagent, the deproteinized solution and the cleaning solution enter the main channel 102 in the needle valve 101 through the flow pipe 3, and the second channel 104 passes through the flow path The tube 3 is connected to the third pump body 6, so that the cleaning liquid can pass through the third pump body 6 smoothly and enter the waste liquid bag 7, so as to facilitate the cleaning of the flow path.

Abstract

The invention discloses a blood gas analyzer which comprises a needle valve arranged in a sampling frame, a sample box connected with the needle valve, a first pump body connected with the sample box, a waste liquid bag connected with the first pump body, a liquid detector connected with the needle valve and the second pump body, a third electromagnetic valve connected with the liquid detector, a first electromagnetic valve connected with the second pump body and a third pump body connected with the needle valve and the waste liquid bag, wherein in the sample box, one end of a front detector is connected with the needle valve, while the other end of the front detector is sequentially connected with a detection membrane pipe and a rear detector, and the rear detector is connected with the first pump body; the above parts are connected through flow pipes; a memory is connected with the detection membrane pipe through an electrode; and the first electromagnetic valve and the second electromagnetic valve are both provided with air inlets. According to the invention, a gas-liquid mixed calibration method in the prior art is replaced by liquid calibration, so that the method is more convenient for use, and faults caused by that liquid enters an air path are avoided, the fault probability is reduced, and the reliability of the analyzer is improved.

Description

technical field [0001] The invention relates to the field of medical testing, in particular to a blood gas analyzer and a method for using the same. Background technique [0002] The PCO2 and PO2 electrodes of existing domestic blood gas analyzers are calibrated using two compressed gases with different gas ratios, high gas and low gas, which are decompressed, kept warm, and humidified, and then introduced into the electrode measurement channel for calibration, and the rest of the electrodes use standard liquids target. In this calibration method, the flow path is divided into gas path and liquid path, and the control of the gas-liquid intersection is more complicated. Especially in the case of a failure, the calibration liquid or cleaning liquid enters the gas path and easily damages the solenoid valve. In addition, Due to the existence of gas cylinders, the instrument is not convenient to be portable or hand-push, which makes the standard gas transportation inconvenient; ...
