Twist seal oral fluid delivery device
An oral fluid delivery device is described. The device includes a housing forming at least one cavity. The cavity includes at least two reservoirs, a first reservoir and a second reservoir. The device also includes an elongated neck with a distal end having at least one distal opening for passage of a fluid, a proximal end, and a channel fluidly connected to the distal opening. The device also includes a cap at the proximal end of the elongated neck. The cap includes at least one aperture aligned with the channel of the elongated neck and is rotatably coupled to the housing such that rotating the cap relative to the housing selectively aligns the aperture with a first reservoir opening to provide fluid communication between the first reservoir and the channel, or aligns the aperture with a second reservoir opening to provide fluid communication between the second reservoir and the channel.
1. A method of using an oral cleaning device for oral care, comprising:
providing an oral cleaning device comprising:
a housing forming at least one cavity, the at least one cavity housing a fluid reservoir and a suction channel;
an elongated neck comprising a distal end having at least one distal opening for passage of a fluid, a proximal end, and a neck channel fluidly connected to the distal opening; and
a cap at the proximal end of the elongated neck, wherein the cap comprises at least one aperture aligned with the neck channel of the elongated neck;
wherein the cap is rotatably coupled to the housing, and wherein the cap is rotatable between a maximum position in a first direction and a maximum position in a second direction, wherein rotating the cap to the maximum position in the first direction causes the at least one aperture of the cap to be aligned with an opening in the fluid reservoir and wherein rotating the cap to the maximum position in the second direction causes the at least one aperture of the cap to be aligned with an opening in the suction channel; and
rotating the cap relative to the housing to selectively:
align the at least one aperture with the opening in the fluid reservoir to provide fluid communication between the fluid reservoir and the neck channel, or
align the at least one aperture with the opening in the suction channel to provide fluid communication between a vacuum source and the neck channel.
2. The method of claim 1 , further comprising rotating the cap relative to the housing to selectively align the at least one aperture with a top of the housing such that the at least one aperture is not in fluid communication with either the opening in the fluid reservoir or the opening in the suction channel.
3. The method of claim 1 , further comprising:
rotating the cap to provide fluid communication between the neck channel and the fluid reservoir; and
activating a fluid mechanism to provide fluid from the fluid reservoir, through the neck channel, and out the distal opening.
4. The method of claim 3 , wherein the fluid reservoir includes a deformable fluid container comprising a frangible element preventing the flow of the fluid from the fluid reservoir to the neck channel, and wherein activating the fluid mechanism comprises exerting a force on the deformable fluid container to break the frangible element, thereby allowing fluid to flow through the neck channel and out the distal opening.
5. The method of claim 1 , further comprising:
coupling the suction channel to the vacuum source;
rotating the cap to provide fluid communication between the neck channel and the vacuum source.
6. The method of claim 5 , further comprising obstructing a suction adjustment opening in the suction channel to cause suction to be provided through the neck channel and to the distal opening.
