title: [Instruments and probes for intracavitary pH measurement].
abstract: The modern clinical tasks, related with intracavitary pH-metry, are highly diversified. It is necessary to work out a whole series of instruments in order to meet the demands of both the practical and the scientific medicine in respect to pH-metry. Such designing of instruments must be based on an analysis of demands related with clinical tasks and with technical-and-economic factors. The article contains a list of such instruments and a description of their practical value, which include: a cheap and microprocessor-based acidogastrometer, a computer-based and multi-seater acidogastrometer, a 24-hour acidogastro-monitor and a comprehensive device designed for examining simultaneously the acidity and other parameters (electrocardiogram and electrogastrogram). The worked out series of instruments meets the key requirements of Russian medicine in respect to intragastric pH-metry and ensures a good competition with foreign companies in the home market.
