Abstract
A drip chamber splash guard comprising an annular member receivable within the upper end of the chamber. The guard has one periphery thereof engaged adjacent a centrally located drip sleeve depending below the vented top inwardly of the vents for maintenance of a free flow of air inwardly through the vents. The other periphery of the splash guard member engages adjacent the inner surface of the surrounding chamber outward of the vents. Limited air discharge openings are provided at spaced points about the guard whereby inwardly directed air flow is maintained through the splash guard itself while the filter vents are protected against gross or excessive splashing. In a preferred embodiment, the splash guard will be in the form of a truncated conical member with the air openings adjacent the chamber wall remote from the drip sleeve, the conical configuration, providing a tapered surface for a more effective deflecting of splash.
