Heidelberg pH Capsules

Heidelberg pH Capsule

The Heidelberg pH Capsule measures about 8 mm Diameter x about 21 mm Length. It is Encapsulated within a sealed Polyacrylate (plastic) Capsule, which is designed to be easily swallowed. The pH Capsule is NOT RADIOACTIVE (Absolutely NOT). It is a high-frequency Micro-Electronic Transmitter, designed specifically for Inter Abdominal pH Monitoring. The Power source for the pH Capsule is a, Physiologic battery, which operates off approximately one grain of Salt derived from Normal 0.9 Saline. The interior of the Battery Compartment contains a Pure Zinc Electrode, and Pure Silver Electrode, surrounded by a highly absorbent Silica. When the pH Capsule is immersed in the Normal 0.9 Saline, the Silica absorbs the Saline into the Battery Compartment. The Saline become an Electrolyte for the Battery operation, and promotes the transfer of electrons from the Zinc Electrode to the Silver Electrode, this flow of electrons will power the pH Capsule for many hours.
The pH Capsule is swallowed, with one ounce of water. It reaches the Stomach usually within 2 to 3 seconds. The pH Capsule may be Tethered to prevent premature migration out of the Stomach. When the pH Capsule is properly positioned in the stomach, and displaying the pH Levels on the Graph, a small piece of Medical tape is placed over the exposed Tether, on the Patient’s cheek, to prevent migration out of the Stomach. The Stomach’s Parietal Cells may then be challenged with a Saturated Solutions of Sodium Bicarbonate, to determine the Parietal Cell activity, and re-acidification time.
The pH capsule will record the strength of acid (pH) information and display immediate changes resulting from alkaline or acidic “challenge” to the Patient’s stomach. The strength of the acid (pH), time required to reacidify or alkalize the stomach will be displayed on the computer displayed graph.
