The basic structure
of blood gas analyzer
are divided into electrode, pipeline and circuit three most (blood
gas analyzer medical equipment work principle diagram shown below)
Be measured inblood samples of the suction piping system, to sample the measurement of indoor capillary. Measuring capillary wall open has four holes, hole, PCO2 were inserted with pH PO2 and three teams of measuring electrode and a CST electrode. Among them, the pH and pH and composed than electrode to pH value measurement system. Blood samples into the sample room of the measurement and piping system to stop pump, sample is also four electrode are measured. Electrode produce corresponding to the pH, PCO2 PO2 and three parameters of electrical signals. These signals through enlargement, module respectively after conversion to micro processor. The computer processing system treatment, operation, and then be sent to their respective shows respectively unit shows or printer to print out measurement results. The measurement system all parts including temperature control, piping system of movement, all by microcomputer or computer chip control.
Measuring room must be is a constant temperature system. Early measurement chamber of auto blood gas analyzer adopts water bath type, keeps style, etc. At present has been solid thermostatic type device instead.
Blood gas analyzer medical analyzer is the method of a kind of relative measurement method. In the measurement of samples before, need liquid and gas determine standard standard pH, PCO2 PO2 and three sets of electrode work curve.
