Balloon Base Rib for Oral Cavity Pressure Probe Positioning

The rib is pre-formed on the balloon base as a positioning structure that automatically contacts the teeth when the balloon is inserted into the oral cavity. This preliminary structural feature ensures that the balloon is positioned at the correct depth without requiring complex insertion procedures or additional adjustment steps, thereby maintaining ease of operation while improving measurement precision through consistent placement.

The mechanical system of manual depth control is replaced by a passive mechanical stop mechanism. The rib on the balloon base acts as a physical barrier that contacts the teeth to prevent over-insertion, while also serving as a positioning feature that ensures the balloon reaches the appropriate depth. This mechanical substitution eliminates the variability of manual insertion depth control and ensures consistent positioning for accurate measurement.

Instead of adding a complex overall positioning system to the entire balloon assembly, the invention applies a localized quality enhancement by adding a simple rib structure only to the balloon base. This localized feature provides the necessary positioning function without complicating the rest of the balloon structure or the insertion mechanism, thereby improving measurement precision while minimizing the increase in device complexity.
