ABSTRACT:
The present invention is for a device and a gel method for controlling pH by acidic buffering. The device is made of a flexible dome, a flexible circular rim and an absorbent acidic buffer. The flexible dome is attached at its margin to the circular rim and the absorbent acidic buffer is contained within the device. The absorbent acidic buffer can control or maintain pH within physiological ranges. The gel method for controlling pH by acidic buffering is accomplished by applying a gel to an area where the pH is to be controlled. The gel includes an acidic buffering polymer which can control or maintain the pH of the area within the range of about 3 to about 5.
