A high-speed electrolyte analysis device

Abstract

The invention provides a flow injection type high speed electrolyte analysis apparatus. The electrolyte analysis apparatus which comprises a sample and standard solution supply device, connecting pipelines, an ion selective electrode set, and a measure circuit which is connected with the ion selective electrode set and also comprises a rotary sampling valve is characterized in that: a first inlet of the rotary sampling valve is communicated with an output pipeline of the sample and standard solution supply device; a second inlet of the rotary sampling valve is communicated with a carrier liquid container; a peristaltic pump for pumping a carrier liquid is arranged between the second inlet of the rotary sampling valve and the carrier liquid container; a first outlet of the rotary sampling valve is communicated with the ion selective electrode set; a second outlet of the rotary sampling valve is communicated with a waste water container; and a peristaltic pump for pumping a sample and a standard liquid is arranged between the second outlet of the rotary sampling valve and the waste water container. The electrolyte analysis apparatus of the present invention has the advantages of simple structure, fast analysis speed, and improvement of the accuracy and the speed of electrolyte analysis.

Description

technical field [0001] The invention relates to an electrolyte analysis device, in particular to a flow injection electrolyte analysis device. Background technique [0002] Potassium (K+), sodium (Na+), chlorine (Cl-) and calcium (iCa++) in human blood are the main components of human electrolytes, and the content of K+, Na+, Cl-, iCa++, in the patient's blood can be obtained for clinicians to diagnose Disease and implementation of treatment are critical. [0003] At present, the instruments for measuring potassium, sodium, chloride and calcium ions in blood mainly use electrolyte analyzers based on ion selective electrode method. However, with the increase of urban population density, the direct impact on the hospital is that more and more people seek medical treatment, and more and more specimens are sent for examination. The analysis speed of the specimens for examination directly affects the doctor's treatment efficiency efficiency. In order to reduce the impact of th...

Problems solved by technology

[0006] In addition, in the sample and standard solution supply part of the existing electrolyte analysis module using the static analysis method, the reagents and samples generally enter the ion-selective electrode through the reagent switching valve, because the reagent switching valve and the ion-selective electrode will adsorb the sample (serum) The protein in the electrolyte will affect the subsequent sample analysis. At this time, if the influence is to be eliminated, the reagent switching valve and the ion-selective electrode need to be thoroughly cleaned, which will affect the speed of electrolyte analysis.
