US Patent 12083273 Vacuum shield assembly for attachment to medical masks

A vacuum shield assembly intended for attachment to an existing medical mask for air suction, nebulization, BIPAP, and/or CPAP. The vacuum shield assembly generally comprises a shield body and a retaining assembly. The retaining assembly may attach the vacuum shield assembly to a vacuum tube of the existing mask, which may be connected to a negative pressure vacuum. The retaining assembly may also be attached to a nebulizer unit or component thereof, or to an oxygen supply tube of a BIPAP or CPAP mask. The shield body may comprise a lower segment, which may comprise a connecting component configured and dimensioned for attachment to, and for a fluid communication, with the retaining assembly. The shield body may be configured and dimensioned to correspond to the geometry of the existing mask. As an example, the shield body may comprise a substantially concave configuration with a substantially semi-ovoidal edge.
