Abstract: An electric toothbrush is disclosed, having a handle including a drive motor and a head portion removably coupled to the handle. The head portion includes a brush, an exit port fed by an internal irrigation lumen, and a drive shaft operatively connecting the drive motor to the brush. A disposable irrigant reservoir is removably coupled directly to the head portion. The irrigant reservoir is in fluid communication with the internal irrigation lumen of the head portion. The head portion is configured to be replaceable with respect to the handle, and the irrigant reservoir is configured to be replaceable independent of the head portion. In some examples, the irrigant reservoir is a disposable bulb (e.g., a capsule), and is positioned such that the user can hold the handle while also squeezing the reservoir with the same hand. In some examples, the toothbrush head includes a suction mechanism.

Abstract: 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.
