The device ejects a gentle flow of fluid under pressure. The fluid stream provides a high quantity of fluid at low pressure. The low pressure fluid stream is more comfortable for a user than a high pressure fluid stream that is delivered by some types of pressurized cans of solution. ## Claims ### Claim 1 A nasal rinse device, comprising: a body surrounding a chamber; a valve; an actuator having a fluid path that is fluidly connected to the chamber when the valve is in an open position; and a nasal rinse tip configured to redirect a flow of nasal rinse solution exiting the actuator as a spray, wherein the nasal rinse tip has a distal portion and a proximate portion and defines an interior cavity that is unobstructed along a longitudinal axis of the nasal rinse tip and that extends from an opening at the proximate portion toward a plurality of exit apertures at the distal portion, the distal portion defining a stop forming a flow obstruction positioned along the longitudinal axis of the nasal rinse tip so as to intercept the flow of nasal rinse solution as the flow of nasal rinse solution moves along the longitudinal axis of the nasal rinse tip and throughout the interior cavity and so as to redirect the intercepted flow of nasal rinse solution around the flow obstruction and to the plurality of exit apertures for ejection; said distal portion having a conical shape, with a convex curved surface leading from the exit apertures toward the proximate portion. ### Claim 2 (depends on 1) The nasal rinse device of claim 1, wherein the distal portion defines an annular chamber connecting the flow obstruction and the plurality of exit apertures. ### Claim 3 (depends on 2) The nasal rinse device of claim 2, wherein a greatest extent of the plurality of exit apertures together is greater than an external circumference of the annular chamber. ### Claim 4 (depends on 3) The nasal rinse device of claim 3, further comprising a circular chamber between the elongated interior cavity and the annular chamber. ### Claim 5 (depends on 2) The nasal rinse device of claim 2, wherein the annular chamber has an external circumference that is greater than a circumference of the flow obstruction. ### Claim 6 (depends on 5) The nasal rinse device of claim 5, wherein the distal portion defines an annular chamber connecting the flow obstruction and the plurality of exit apertures. ### Claim 7 (depends on 6) The nasal rinse device of claim 6, wherein a greatest extent of the plurality of exit apertures together is greater than an external circumference of the annular chamber. ### Claim 8 (depends on 7) The nasal rinse device of claim 7, further comprising a circular chamber between the elongated interior cavity and the annular chamber. ### Claim 9 (depends on 6) The nasal rinse device of claim 6, wherein the annular chamber has an external circumference that is greater than a circumference of the flow obstruction. ### Claim 10 (depends on 1) The nasal rinse device of claim 1, wherein the flow obstruction is positioned in line with the actuator, such that a longitudinal axis of the actuator extends through the flow obstruction. ### Claim 11 A nasal rinse device, comprising: a body surrounding a chamber; a valve; a tube within the chamber and connected to the valve; an actuator having a fluid path that is fluidly connected to the chamber when the valve is in an open position; and a nasal rinse tip configured to redirect a flow of nasal rinse solution exiting the actuator as a spray, wherein the nasal rinse tip has a distal portion and a proximate portion and defines an interior cavity that is unobstructed along a longitudinal axis of the nasal rinse tip and that extends from an opening at the proximate portion toward a plurality of exit apertures at the distal portion, the distal portion defining a stop forming a flow obstruction positioned along the longitudinal axis of the nasal rinse tip so as to intercept the flow of nasal rinse solution as the flow of nasal rinse solution moves along the longitudinal axis of the nasal rinse tip and throughout the interior cavity and so as to redirect the intercepted flow of nasal rinse solution around the flow obstruction and to the plurality of exit apertures for ejection. ### Claim 12 (depends on 11) The nasal rinse device of claim 11, wherein an exterior of the nasal rinse tip tapers outwardly between the distal portion and the proximate portion. ### Claim 13 (depends on 12) The nasal rinse device of claim 12, wherein the exterior is curved between the distal portion and the proximate portion. ### Claim 14 (depends on 11) The nasal rinse device of claim 11, wherein the distal portion defines an annular chamber connecting the flow obstruction and the plurality of exit apertures. ### Claim 15 (depends on 14) The nasal rinse device of claim 14, wherein a greatest extent of the plurality of exit apertures together is greater than an external circumference of the annular chamber. ### Claim 16 (depends on 15) The nasal rinse device of claim 15, further comprising a circular chamber between the elongated interior cavity and the annular chamber. ### Claim 17 (depends on 14) The nasal rinse device of claim 14, wherein the annular chamber has an external circumference that is greater than a circumference of the flow obstruction. ### Claim 18 (depends on 11) The nasal rinse device of claim 11, wherein the flow obstruction is positioned in line with the actuator, such that a longitudinal axis of the actuator extends through the flow obstruction. ### Claim 19 A nasal rinse device, comprising: a body surrounding a chamber, said body comprising an aerosol type can; a valve; an actuator having a fluid path that is fluidly connected to the chamber when the valve is in an open position; and a nasal rinse tip configured to redirect a flow of nasal rinse solution exiting the actuator as a spray, wherein the nasal rinse tip has a distal portion and a proximate portion and defines an interior cavity that is unobstructed along a longitudinal axis of the nasal rinse tip and that extends from an opening at the proximate portion toward a plurality of exit apertures at the distal portion, the distal portion defining a stop forming a flow obstruction positioned along the longitudinal axis of the nasal rinse tip so as to intercept the flow of nasal rinse solution as the flow of nasal rinse solution moves along the longitudinal axis of the nasal rinse tip and throughout the interior cavity and so as to redirect the intercepted flow of nasal rinse solution around the flow obstruction and to the plurality of exit apertures for ejection. ### Claim 20 (depends on 19) The nasal rinse device of claim 19, wherein the flow obstruction is positioned in line with the actuator, such that a longitudinal axis of the actuator extends through the flow obstruction.
