A kind of vim and vigour blomelicalbloodgasandelectrolrteanalyzers sensor electrode

Technical field

The utility model relates to the vim and vigour blomelicalbloodgasandelectrolrteanalyzers, especially a kind of dull and stereotyped Integrated electrode of vim and vigour blomelicalbloodgasandelectrolrteanalyzers sensor electrode.

Background technology

In medical diagnosis, very important to being determined in state of an illness diagnosis and the treatment of some indexs of patient blood, as pH value, hematocrit, ion concentration (K+, Na+, Cl-, Ca2+), glucose, lactic acid and O ₂, CO ₂Dividing potential drop or the like.Advantages such as electrochemical sensor is simple to operate because of it, and is quick, sensitive, accurate more and more are used in medical analysis and the clinical diagnosis.Existing electrochemical sensor electrodes volume is big, consume calibration solution and sample size many; Because electrode all is independently, each electrode needs periodic maintenance, and each cycle electrode life do not wait, change frequently, operating personnel are required height; Such vim and vigour blomelicalbloodgasandelectrolrteanalyzers sensor electrode can't adapt to the trend of bringing in constant renewal in the medical market of regenerating, also can't satisfy the unspecialized requirement of instrumentation.

The utility model content

The purpose of this utility model provides a plurality of parameters of a kind of fast measuring, vim and vigour blomelicalbloodgasandelectrolrteanalyzers sensor electrode easy and simple to handle, comprising: the PVC substrate; The flow of solution pond; The reference liquid flow cell; Electrode chamber; Reference cell; Described PVC substrate is a slab construction; Flow of solution pond, reference liquid flow cell, electrode chamber, reference cell are positioned in the dull and stereotyped PVC substrate.

Above-mentioned flow of solution pond is made up of solution injection port, electrode chamber and waste liquid mouth, and the flow of solution pond is circular-arc at corner part, can increase flow of solution, avoids washing the dead angle.

Above-mentioned flow of solution pond, duct wall is handled through hydrophobic.

Above-mentioned reference liquid flow cell is made up of reference liquid injection port, reference cell and waste liquid mouth, and the reference liquid flow cell is circular-arc at corner part, can increase flow of solution, avoids washing the dead angle.

Above-mentioned reference liquid flow cell, duct wall is handled through hydrophobic.

Above-mentioned electrode chamber is positioned in the middle of the flow of solution pond, comprises Na, K, Cl, Ca, pH ion electrode, O ₂, CO ₂Gas sensitization electrode, and glucose, lactalase electrode; Each electrode is in one line.

Above-mentioned reference cell is positioned in the middle of the reference liquid passage, and reference liquid is AgNO ₃Solution, contrast electrode are Ag/AgNO ₃Electrode; Each test electrode of contrast electrode and electrode chamber and electrode Pt constituted test loop in solution is measured the electric signal of each test parameter on electrode.

Integrated form sensor electrode of the present utility model is integrated in a plurality of ionic electrolytes electrodes, gas sensitization electrode and enzyme electrode on one Zhang Ping's plate electrode, utilize the parameter that a spot of sample size just can be measured exactly simultaneously needs detection, greatly reduce requirement operating personnel.This sensor electrode rationally, effectively circuit design has also been avoided the air bubble problem in the traditional electrode pipeline, has increased measurement accuracy.

Description of drawings

Fig. 1 is the structural representation of a kind of vim and vigour blomelicalbloodgasandelectrolrteanalyzers of the utility model sensor electrode.
