CLAIMS

1. A medicament delivery device comprising:

a first tubular section;

a second tubular section;

a bendable section connecting the first tubular section to the second tubular section;

a cap having a compartment holding a medicament including a sealable opening,

wherein removal of the sealable opening causes the medicament to flow through the first or second tubular sections and into the bendable section; and

a nasal fitting located on the first tubular section or the second tubular section; wherein the nasal fitting forms an airtight seal with the naris of a user when the nasal fitting is inserted into the naris.

2. The medicament delivery device according to claim 1, wherein the nasal fitting comprises a plurality of multi-tiered pliable rings of increasing diameter.

3. The medicament delivery device according to claim 1, wherein the nasal fitting is a conical shape having a smooth surface.

4. The medicament delivery device according to claim 1, further comprising: a cone-shaped tip located at a proximal end of the second tubular section, wherein the nasal fitting is located along the second tubular section, and wherein the cone-shaped tip extends beyond the nasal fitting such that the cone-shaped tip is located completely within a nasal cavity of the user when the nasal fitting is inserted into the naris of the user.

5. The medicament delivery device according to claim 4, wherein sides of the proximal end of the second tubular section are angled inwards at 30-40 0 to form the cone-shaped tip.

6. The medicament delivery device according to claim 5, wherein the sides of the proximal end of the second tubular section are angled inwards at 38 °.

7. The medicament delivery device according to claim 1, wherein the first tubular section comprises a pinch valve along its length and markings to indicate a location of the pinch valve.

8. The medicament delivery device according to claim 7, wherein the pinch valve comprises a softer material than that used to form the first tubular section.

9. A medicament delivery device comprising:

a first tubular section;

a second tubular section;

a bendable section connecting the first tubular section to the second tubular section;

a cap having a compartment holding a medicament including a sealable opening,

wherein a proximal end of the second tubular section is located within the cap and abuts the sealable opening,

wherein removal of the sealable opening causes the medicament to flow through the first or second tubular sections and into the bendable section; and

a one way valve located along an interior of the first tubular member, wherein the one way valve allows airflow from the first tubular section to the second tubular section and restricts airflow from the second tubular section to the first tubular section.

10. The medicament delivery device according to claim 9, wherein the one way valve is a diaphragm check valve, a swing check valve, a stop-check valve, a lift-check valve, an in-line check valve, a duckbill valves, and a pneumatic non-return valve.

11. The medicament delivery device according to claim 9, further comprising: a second one way valve located in series with the one way valve along the interior of the first tubular member.

12. The medicament delivery device according to claim 9, wherein the one way valve comprises:

an air inlet section having a tapered valve seal, an air inlet, and a first mating portion;

an air outlet section having an abutment surface, an air outlet, and a second mating portion,

wherein the first mating portion is jointed to the second mating portion;

a shaft having a scaffold construction,

wherein the shaft has a proximal end and a distal end, and

wherein the proximal end of the shaft comprises a valve formed

circumscribing the shaft; and

a spring surrounding the distal end of the shaft,

wherein a proximal end of the spring abuts the abutment surface and a distal end of the spring exerts a biasing force against the valve, causing the valve to form an airtight connection with the tapered valve seal to restrict airflow from the air outlet section to the air inlet section.

13. The medicament delivery device according to claim 12, wherein, when the air inlet receives an airflow force greater than the biasing force of the spring, the spring is compressed and the airtight connection is removed, allowing airflow from the air inlet to the air outlet.
