The invention relates to medicine and can be used for research

acid-forming and neutralizing

functions of the stomach.

The drawing shows the scheme of the probe.

The probe consists of a casing 1, two cylindrical tubes 2 and 3 installed coaxially with the possibility of mutual displacement, antimony electrodes 4 and 5 are mounted on the working ends of tubes 2 and 3. On the casing 1 there are mounted clamps 6 and 7 respectively of tubes 3 and 2 The electrodes 4 and 5 are connected by conductors 8 and 9 with the device 10 minimum pH determination via connector 1 1. ,

The probe under radiological control is introduced into the stomach and the electrode 4 is installed in the prepyloric part of the stomach, the fixer 7 fixes its position relative to the housing 1. Next, the electrode 5 is removed from the electrode 4 and the lowest pH value is determined using the device 10. With the help of the fixer 6, the tube 3 is fixed. If necessary, the distance between the zone of maximum acid formation and the neutralizing zone is determined on the non-working end of tube 2, calibrated in millimeters.

1. Probe for the study of acid-forming and neutralizing functions of the stomach, containing an elastic tube and antimony and calomel electrodes connected to a measuring device, characterized in that, in order to improve measurement accuracy in the study of acid-forming and neutralizing functions of the stomach, it is equipped with an additional elastic tube, elastic the casing and fixing unit, while the main, additional tubes and casing are installed coaxially with the possibility of mutual longitudinal movement, and on the working end Antimony electrodes are attached to the tubes.

2. Probe π. 1, characterized in that the fixing unit is placed on the non-working end of the casing and contains clamps associated with each of the tubes.

3. Probe π. 1, characterized in that, in order to reduce the time of the study by registering the dependence of the lowest pH value with the distance between the electrodes, the electrodes are connected to the unit for determining the minimum pH.
