Electrolyte analyzer five big system analysis

Electrolyte analyzer mainly by the circuit system, board face system, software system, electrode system, liquid road systems. Specific system composition perlong medical equipment expert analysis are as follows:
   First, electrolyte analyzer circuit of the system
   All kinds of electrolyte analyzer circuit system of basic module is normally by power supply circuit module, micro processor module, input/output module, amplification and data acquisition module, the peristaltic pump and the 3-way valve (pos control module on the five modules.
   Power supply circuit module mainly provide analyzer printer interface circuit, the wriggle pump control circuit, electromagnetic valve control circuit and other various parts of the required power supply.
   Second, electrolyte analyzer the board face system
   Electrolyte analyzer in the instrument on board with the man-machine dialogue operation key. On board with the "Yes" or "No" two key, the "Yes" button used to receive a display questions, "No" keys are used to deny display questions.

   Third, electrolyte analyzer software system
   All kinds of analyzer like blood gas analyzer this medical equipment is also software system, the key is to control instrument operation. It provides the instrument system operation, micro instrument setup program operation, instrumental determination program operation and automatic cleaning operation procedures.
  The electrode determination system is analyzer samples of the key, decided to the accuracy of determination results and sensitivity. Electrode systems including instructions and reference electrode than electrode. Instructions electrode including pH, Na +, K +, Li +, Cl-Ca2 +, Mg2 + plasma selective electrode. And electrode is generally than silver/silver chloride electrode.
   Fifth, electrolyte analyzer of liquid road system
   Liquid road system directly affect the accuracy of the determination of sample concentration and stability. The liquid electrolyte analyzer road system is usually specimens dish, solution bottle, suck sample needle, the 3-way valve (pos, electrode systems, wriggle pump etc. For all kinds of reagent wriggle pump flow provide motivation, specimens plate, the 3-way valve (pos and peristaltic pump rotation, convert all by microcomputer automatic control. Liquid in the system by scaling road access liquid/rinses pathways, specimen pathways, waste liquid access, backwater access, electromagnetic valve pathways etc.
