Abstract

A device, a system and a method are provided to accurately apply a medically beneficial substance directly to a laterally or superiorly located paranasal sinus cavity. When the device is assembled with a solution in a reservoir, and inverted such that the reservoir is above an input apparatus and a housing, weight of the solution pushes down on a diaphragm creating a negative pressure on the diaphragm, which prevents air from entering the reservoir and prevents a liquid from flowing out of the reservoir. Applying a positive pressure to a bottom of the diaphragm causes the diaphragm to open and allows air to flow into the reservoir. When a user creates the positive pressure by exhaling air into the device the act of exhaling causes the user'"'"'s choana to close. Thereby any solution introduced into the user'"'"'s sino-nasal cavity will remain contained within the user'"'"'s sino-nasal cavity increasing effectiveness of treatment and decreasing user discomfort including gagging, choking, and inner ear disturbance. When the positive pressure on the bottom of the diaphragm is removed, the flow of the liquid from the reservoir stops.

Claims

1. A device for delivering a solution to a sino-nasal cavity of a user, the device comprising:

a reservoir container;

a housing adapted to connect to the reservoir container wherein the housing has a nose tube and a grinding chamber with a filter in the housing and a plurality of grinding teeth extending perpendicular to the filter;

an input apparatus adapted to connect to the housing wherein the input apparatus has a mouth piece connected to a tube and the tube is connected to a L-connector of the input apparatus; and

,

a mortar with a first end and a second end.

2. The device for delivering the solution to the sino-nasal cavity of the user of claim 1 wherein the mouth piece is removably attached to a first terminal end of the tube and a diaphragm is interposed at the L-connector of the input apparatus.

3. The device for delivering the solution to the sino-nasal cavity of the user of claim 1 wherein the mortar has the first end with a recess containing a plurality of grinding teeth and the second end with a plurality of tines configured to align with a plurality of holes in the filter.

4. The device for delivering the solution to the sino-nasal cavity of the user of claim 3 wherein the mortar further comprises a removable cap that frictionally engages the mortar and covers the tines of the second end of the mortar.

5. The device for delivering the solution to the sino-nasal cavity of the user of claim 1 further comprising a tip with directional flow that is removably attached to a distal end of the nose tube.

6. A device for delivering a solution to a sino-nasal cavity of a user, the device comprising:

a reservoir container adapted to removably engage a housing wherein the housing has a nose piece with a nasal tip adapted to removably attach to a terminal end of the nose piece;

an input apparatus with a tube that connects a mouth piece to a L-connector of the input apparatus wherein the mouth piece is adapted to removably connect to the housing; and

a mortar with a first end with a plurality of grinding teeth and a second end with a plurality of tines.

7. The device for delivering the solution to the sino-nasal cavity of the user of claim 6 wherein the tube has a first terminal end with the mouth piece removably attached and the L-connector of the input apparatus with a diaphragm interposed between the L-connector and a bottom of the input apparatus.

8. The device for delivering the solution to the sino-nasal cavity of the user of claim 7 wherein the diaphragm permits air flow into the reservoir container when a positive pressure exists in the tube.

9. The device for delivering the solution to the sino-nasal cavity of the user of claim 7 wherein the diaphragm prevents gravity flow of the solution from the reservoir container when a positive pressure does not exist in the tube.

10. The device for delivering the solution to the sino-nasal cavity of the user of claim 7 wherein the plurality of tines of the second end of the mortar are configured to match a plurality of holes in a filter.

11. The device for delivering the solution to the sino-nasal cavity of the user of claim 6 further comprising a nasal tip extension with directional flow adapted to removably engage the terminal end of the nose piece or the nasal tip.

12. The device for delivering the solution to the sino-nasal cavity of the user of claim 6 wherein the housing has a grinding chamber with a filter comprising a plurality of holes in the housing.

13. The device for delivering the solution to the sino-nasal cavity of the user of claim 6 wherein the nasal tip is selected from the group consisting of:

a nasal tip to accommodate nasal opening sizes of children;

a nasal tip to accommodate nasal opening sizes of adults; and

, a nasal tip to accommodate nasal opening sizes of larger adults.

14. A device for delivering a solution to a sino-nasal cavity of a user, the device comprising:

a reservoir container adapted to removably engage a housing wherein the housing has a nose piece with a nasal tip adapted to removably attach to a terminal end of the nose piece;

the housing further comprising a grinding chamber with a filter in the housing consisting of a plurality of holes in the housing and a plurality of grinding teeth extending perpendicular to the filter; and

,

an input apparatus with a tube with a mouth piece at a first terminal end of the tube and a diaphragm at a second terminal end of the tube that connects to a L-connector of the input apparatus.

15. The device for delivering the solution to the sino-nasal cavity of the user of claim 14 wherein the diaphragm has a first closed position that prevents gravity flow of the solution in the reservoir container when a positive pressure does not exist in the tube and a second open position that permits air flow into the reservoir container when the positive pressure exists in the tube.

16. The device for delivering the solution to the sino-nasal cavity of the user of claim 14 further comprising a nasal tip extension with directional flow adapted to removably engage the terminal end of the nose piece or the nasal tip.

17. The device for delivering the solution to the sino-nasal cavity of the user of claim 14 further comprising a mortar with a first terminal end with a plurality of grinding teeth and a second terminal end with a plurality of tines.

18. The device for delivering the solution to the sino-nasal cavity of the user of claim 17 wherein the plurality of tines of the second terminal end of the mortar are configured to match the plurality of holes of the filter.
