â‘ When should the blood gas analyzer need to be replaced?
In general, when the pressure indicator shows 150-200psi or 10bar, the gas needs to be replaced.
â‘¡What is the difference between domestic steel cylinders and imported special steel cylinders:
Generally, the internal surface of domestic steel cylinders is very rough. Due to the gas pressure and molecular activity capacity, the gas in the cylinders is prone to different molecular adsorption and penetration, and the internal surface of imported special steel cylinders is coated with a special molecular film to effectively control these problems.
â‘¢What is the difference between the shelf life of domestic steel cylinders and imported special steel cylinders:
Due to the different internal surface structure of the steel cylinder and the size of the molecule's own activity, the gas concentration will change with time. Under normal circumstances, the shelf life of the gas contained in the domestic steel cylinder is 18 months, and the shelf life of the imported steel cylinder is generally 2 years.
â‘£What effect does the change of gas concentration have on blood gas analyzer:
a: make the inspection report inaccurate
b: The blood gas analyzer cannot be calibrated and the instrument cannot be used normally
c: Causes changes in the sensitivity of the inspection electrode, and long-term use will cause irreversible damage to the electrode
⑤Why sometimes the instrument cannot be calibrated after a bottle of gas is used for a long time, and the instrument can be used normally after changing to a new gas;
Due to the long time, the gas concentration in the bottle changes
⑹Why can we prepare the standard gas of various types of imported gas cylinders (especially Kangren-348 series, Leidu ABL-700 series)
Because our equipment is fully equipped, we have a variety of special connectors for imported steel cylinders.
⑺The difference between using domestic pressure reducing valve and imported pressure reducing valve:
The blood gas analyzer is a very precise instrument. The pressure reducing valve used must match the original machine, because the gas in the instrument must be analyzed at a certain pressure and a certain flow rate to be accurate. However, domestic pressure reducing valves are basically If this requirement is not met, long-term use of domestic pressure reducing valves will cause inaccurate analysis data and great damage to the instrument.
â‘»How to test the domestic pressure reducing valve can not work with constant pressure and constant current:
We can do such a simple experiment, connect a domestic pressure reducing valve to the gas cylinder, and then connect a rubber tube to the pressure reducing valve, and introduce the rubber tube into the water, so that we can observe the bubbles emerging from the rubber tube , In order to understand the working condition of the pressure reducing valve. Then open the main valve of the gas cylinder and adjust the pressure relief valve button. We can see that the bubbles are evenly emerging from the water. But once we closed the cylinder main valve, we found that the bubbles no longer evenly popped out, but rushed out in an instant. Therefore, the output pressure of the domestic pressure reducing valve will change due to the change of the cylinder pressure. When the pressure reaches a certain level, it will cause huge damage to the instrument, but this will not happen to the inlet pressure reducing valve.
⑼Why when the blood gas analyzer shuts down for a period of time for some reason, CO2 two-point calibration is difficult to pass (especially when the standard gas is used, it is shut down when the gas cylinder is replaced).
This situation is very common in the use of blood gas analyzers, because the CO2 electrode is afraid of drying, especially in the air. Restart the instrument after the blood gas analyzer is shut down, CO2 two-point calibration can not pass for a long time is caused by this reason.
⑽Why does the blood gas analyzer work normally, and when the new standard gas is replaced after shutdown, what is the reason why it can not work normally for a long time?
This kind of situation is especially common for instruments that have been used for more than 3 years. When this happens, you often suspect that the new standard gas concentration is inaccurate. In fact, this situation is caused by the CO2 electrode drying, as long as there are spare bottles This situation does not occur in turn.
⑾Blood gas analyzer is a very precise instrument. We should love it as a child, and more than ten years of practical experience reminds the majority of hospital friends:
â‘ Regular replacement of standard gas (not more than 2 years for imported bottles, not more than 1 and a half years for domestic bottles)
â‘¡It is better to use the original imported pressure reducing valve, do not use the domestic pressure reducing valve
â‘¢ Use standard gas prepared by special manufacturer
â‘£It is best to use imported original gas cylinders
⑤ Equipped with spare gas cylinders, do not stop due to ventilation.
â‘¿Why the spare cylinders that I have launched are popular among the hospitals:
Because the spare gas cylinders I introduced are light weight, compact and flexible, and are equipped with special joints, they can be directly used with the imported pressure reducing valve without replacing the pressure reducing valve.
