Unit and multi dose applicators and methods of use
A dental application device having a handle having a first end, a second end, and a containment chamber disposed within the handle. The device has a dental solution disposed within the containment chamber, a receiver tip coupled to the handle at the first end, a material passage within the receiver tip that forms a conduit between the first end and a receiving end, a frangible seal that separates the containment chamber from the material passage, and a piercing cannula in fluid communication with an applicator tip and having a distal piercing end extending toward the frangible seal. The piercing cannula is moveable between a first position and a second position. When in the first position, the piercing end is spaced apart from the frangible seal, and in the second position, the piercing end punctures the frangible seal and fluidly connects the dental solution with the applicator tip.
1. A dental application device, comprising:
a handle having a first end, a second end, and a containment chamber disposed within the handle;
a dental solution disposed within the containment chamber;
a tip assembly having a piercing end, a stop, and an applicator tip;
a material passage disposed within the tip assembly that forms a conduit between the piercing end and the applicator tip;
a frangible seal that separates the containment chamber from the material passage;
wherein the piercing end protrudes from the distal end of the stop;
wherein the tip assembly is coupled to the first end of the handle, the piercing end punctures the frangible seal and fluidly connects the dental solution with the applicator tip; and
wherein the stop provides tactile feedback prior to the puncturing frangible seal by resisting the movement of the tip assembly relative to the handle.
2. The dental application device of claim 1 , wherein the applicator tip is comprised of an orientation of fibers.
3. The dental application device of claim 1 , wherein the stop is comprised of one or more mating features.
4. The dental application device of claim 1 , wherein the material passage is coupled to a piercing mandrel.
5. The dental application device of claim 1 , further comprising an activator cap coupled to a receiver tip.
