摘要:
A dental suction apparatus 2 includes a tubular vacuum member 10, such as a tubular vacuum tip or aspirator, and a protective foam pad 20. The pad is mounted on a distal end 12 of the tubular vacuum member through a first opening 32 and partially through a second opening 34. In a folded operative position, the foam member 20 not only protects the patients mouth, but creates a larger surface through which fluids and debris particles can be drawn though the influence of a vacuum.
