Embodiment Construction

[0020] Such as figure 1 The shown blood gas analyzer calibration test gas tension balance device is mainly composed of a triode injector (1) and a heater (2) structurally. Wherein, the triode injector (1) has three components: the injector primary tube unit (3), the injector diode unit (4) and the injector triode tube unit (5). Further, the primary material of the syringe primary tube unit (3), the syringe secondary tube unit (4) and the syringe tertiary tube unit (5) is polymethyl methacrylate; the syringe primary tube unit (3) Partially insert the second tube unit (4) of the syringe, and fix it through the first sealing ring (12), the first gasket (13), the second sealing ring (14), and the first cover shell (15); The syringe secondary tube unit (4) is partially inserted into the syringe tertiary tube unit (5), and passes through the third sealing ring (19), the second gasket (20), the fourth sealing ring (21), the second cover shell (22) fix; one end of the three-stage tu...

Abstract

A gas tension balancing device for calibration tests of a blood-gas analyzer is disclosed. The structure of the device is mainly composed of a three-stage injector and a heater. The three-stage injector has three constitutional units: an injector first-stage tube unit, an injector second-stage unit and an injector third-stage tube unit. The heater has two constitutional parts: a heating furnace and a temperature controller. Further, the three-stage injector is directly inserted into a three-stage injector heating trough of the heating furnace, and is heated by an external heating sheet and aninternal heating rod of the heating furnace. The invention aims to provide a method and a device which meet relevant requirements prescribed by the national metrological verification regulations of the People's Republic of China JJG 553-1988 ''Testing Regulations for Blood Gas Acid and Alkali Analyzers'' and are used for transferring uncontaminated tension-balanced gas-liquid samples to use places.

Description

technical field [0001] The invention relates to the field of measurement calibration, in particular, a gas tension balance device for calibration test of a blood gas analyzer Background technique [0002] Blood gas acid-base analyzer (referred to as blood gas analyzer) refers to an instrument that uses electrodes to measure the pH, partial pressure of carbon dioxide (PCO2) and partial pressure of oxygen (PO2) in the artery in a short period of time. . Since Poul Astrup of Denmark developed the first blood gas analyzer in the late 1950s, blood gas analysis technology has been playing a vital role in the diagnosis and treatment of acute respiratory failure, surgery, rescue and monitoring. [0003] The blood gas analyzer is an analytical instrument included in the national compulsory verification catalogue. According to the provisions of Article 19 of the National Metrology Verification Regulations of the People's Republic of China JJG 553-1988 "Blood Gas Acid-base Analyzer Ve...
