Protective solution used for storage process of electrode of upper gastrointestinal tract pH value dynamic monitor

Abstract

The invention provides a protective solution used for the storage process of an electrode of an upper gastrointestinal tract pH value dynamic monitor. The protective solution is prepared from the following materials according to the mass ratio: 5 parts of glycerinum, 3 parts of ethyl alcohol, 12 parts of water, 6 parts of loofah juice and 3.5 parts of white carbon black; the water is heated to 85 DEG C, the glycerinum is dissolved in water, then the white carbon black is added, the mixture is continuously stirred for more than 5 minutes and then refrigerated for 10 minutes at the temperature of subzero 12 DEG C, the temperature is raised to subzero 2 DEG C, the heat is preserved for 5 minutes, the temperature is raised to 20 DEG C, the heat is preserved for 10 minutes, and then the mixture is evenly blended and stirred with the ethyl alcohol and the loofah juice to obtain the protective solution. The protective solution forms a layer of protective layer on the surface of the pH electrode to fulfill the purposes of inhibiting bacteria and resisting corrosion, the detection sensitivity of the electrode is effectively protected, and the electrode is prevented from being damaged in the storage process.

Description

technical field [0001] The invention relates to the field of digestive tract power detection equipment, in particular to a protective solution used in the electrode preservation process of an upper digestive tract pH value dynamic monitor. Background technique [0002] At present, in the clinical monitoring of gastroesophageal reflux in the Department of Gastroenterology, an upper gastrointestinal pH dynamic monitor is usually used to monitor the patient's upper gastrointestinal pH. That is, the electrochemical reaction between the pH electrode probe and the digestive juice with different pH values ​​generates a corresponding voltage signal, and the voltage signal reflects the pH information of the upper digestive tract. The detection accuracy of the pH electrode probe in the prior art is low, which makes the detection value of pH inaccurate and cannot accurately reflect the real situation of the patient in real time. Moreover, the existing upper gastrointestinal pH dynamic...
