Problems solved by technology

[0011] The quality control products produced by the above methods are difficult to avoid the influence of the environment. The high-temperature flame sealing will destroy the gas-liquid two items that have been balanced, which will cause changes in the expected gas concentration in the quality control product bottles, resulting in product quality. Vary and affect product uniformity

Abstract

The invention discloses a production method for a quality control product of a blood-gas electrolyte analyzer. The production method comprises the following steps of: (1) preparing a base buffer solution with set K<+>, Na<+>, Cl<-> and Ca<2+> ionic concentrations; (2) completely balancing CO2, O2 and N2 standard gases with fixed proportion and the base buffer solution in an aluminum foil bag; (3) sealing the aluminum foil bag, driving away the gases in the aluminum foil bag through hands after the base buffer solution and the standard gases are balanced, and then sealing directly after introducing suitable standard gases; and (4) after placing the aluminum foil bag for a period of time, sub-packaging the base buffer solution into small packing bags. According to the production method, the produced quality control product has relatively high uniformity and stability, the impact of air on quality control liquid and gas partial pressure is avoided, and thus the bag uniformity of the quality control product can be ensured effectively, and the quality of the quality control product is improved.

Description

technical field [0001] The invention relates to a production method of a quality control product of a blood gas electrolyte analyzer. Background technique [0002] Blood gas and electrolyte analysis can be used to understand the changes of acid-base balance, oxygen metabolism and osmotic pressure in the body. It is an important monitoring method in the rescue of critically ill patients. Blood gas and electrolyte analysis refers to the detection of different types of gases in various gases and liquids. A technical process for analyzing and monitoring osmotic pressure with acids and bases. Traditional blood gas analyzers can detect hydrogen ion concentration (PH), partial pressure of carbon dioxide (PCO 2 ) and partial pressure of oxygen (O 2 ) and other PH / blood gas items, and according to hydrogen ion concentration (PH), partial pressure of carbon dioxide (PCO 2 ) and partial pressure of oxygen (O 2 ) to calculate AB, BE, SatO 2 、ContQ 2 and other parameters. Next-gen...
