近来,内窥镜pH测量被用于估价胃和胃窦边界的产酸功能和迷走神经完全切除后的局部pH测量。但是,目前的内窥镜pH测量用探头,因易碎不符合研究者的需要,常常遭至失败。作者等研制一种新的内窥镜pH测量探头,pH电极由1毫米直径的铜导线熔化于薄层锑金属上制成。电极末端通过1.5毫米直径的聚四氟乙烯管连结到细导线上,并固定于管端。这种电极远较目前使用的锑电极坚固。锑电极在使用中常常损坏,目前几乎已废弃不用。探头直径不超过1.5毫米,这样不仅适合于各种 Recently, endoscopic pH measurements were used to assess acidogenic function at the gastric and antrum boundaries and local pH measurements after complete excision of the vagus nerve. However, the current probe for endoscopic pH measurement often fails because of its fragility that does not meet the needs of researchers. The authors developed a new endoscopic pH measurement probe, pH electrode made of 1 mm diameter copper wire fused to thin antimony metal. The tip of the electrode was attached to the fine wire by a 1.5 mm diameter Teflon tube and secured to the tube end. This electrode is far stronger than the currently used antimony electrode. Antimony electrode is often damaged in use, almost abandoned now. Probe diameter does not exceed 1.5 mm, so that not only for a variety of
