The diagnostic equipment for functional gastroenterology


Acidigastromonitor GastroScan-24


Intragastric pH-metry is a process of an electrometric measurement of acidity directly in a gastrointestinal tract by a pH catheter and the recorder. This method is based on potential difference occurrence between two electrodes one of which is intended for comparison, and the second for oxidation in an excited environment of GI tract. Intragastric pH-metry include acidity measurement in an esophagus, a stomach and a duodenum.

There are following kinds intragastric pH-metry:


  • Short-term standard intragastric pH-metry (within 2-3 hours), a free mode of selection of drugs and adjustment of drug dosage. The Gastroscan-5 and AGM-03 are applied to these procedures.
  • 24-h gastric рН monitoring (or 24-hours gastric pH-metry). Duration of the procedure is 24 hours or more. The Gastroscan-24Gastroscan-GEM are use.
  • Intraendoscopy pH-metry (during a gastroscopy). The AGM-03 is applied.

Equipment for research of a gastrointestinal motility
stroscan-GEM (Splanchograph) in experiment Mars-500We have two types of instruments to study the motility. The first - the hydravlic capillary infusin manometry system Gastroscan-D with water-perfused multilumen catheters. The second - the device Gastroscan-GEM for recording of a electrical activity due to the gastrointestinal motility using surface electrodes cutaneously.

The Gastroscan-D used in the following tests:
  • Esophageal manometry
  • Advanced upper esophageal sphinter manometry
  • Antroduodenal manometry
  • Anorectal and colonic manometry
The Gastroscan-GEM used for:
  • Short-term standard cutaneous electrogastrography
  • Short-term standard cutaneous electrogastroenterography
  • 24-h cutaneous electrogastroenterography
