Medical nasal respiratory device and uses thereof

2- A medical nasal device according to claim 1 wherein the 2 cuffs are mounted on the free end of the prongs with optional carboxymethylcelluclose or other soothing coating and when adequately inflated ensures sealing of the nasal cavity.

3- A medical nasal device according to claim 1 wherein the 2 cuffs can assume any suitable shape:

• horizontal, pyramidal, pear shaped . . . etc to fix the device in position when adequately inflated.

4- A medical nasal device according to claim 1 wherein the 2 cuffs surround only the free end of the prongs so that no part of the prongs protrudes into the nasal cavity.

5- A medical nasal device according to claim 1 wherein the filling tube and the 2 terminal tubes intermediate between the cuffs on one side and the check valve with the optional pilot ballon on the other side.

6- A medical nasal device according to claim 1 wherein the check valve with pressure relief (with an optional pilot ballon) is attached to the filling tube on one side and fits a detachable syringe on the other side to inject precise volume of air or fluid to the cuffs and prevents its spontaneous deflation to achieve adequate sealing without overinflation and pressure injury or underinflation with disrupted seal.

7- A medical nasal device according to claim 1 wherein the pressure inside the cuffs is high enough to inflate the cuffs so that it ensures adequate sealing, yet it is less than the capillary pressure of the nasal mucosa.

8- A medical nasal device according to claim 1 wherein the device has various sizes to accommodate infants, toddlers and adults of different sizes, races and facial measures.

9- A method for administering a continuous stabilized flow of oxygen supply by using the device aforementioned, wherein the mentioned method comprising the following steps:

• (a) The prongs are inserted into the nostrils with the cuffs deflated until the cuffs completely lie inside the nasal cavities.
• (b) The cuffs are inflated securing the prongs in position to avoid any leak, and then the device is connected to the gas supply wherein an optional mouth strap may be added to ensure further sealing;
• and on removal the air/fluid is drained from the cuffs by actuating the valve using a syringe then the device is pulled out.

10- The method of claim 9 for administering a continuous stabilized flow of oxygen supply by using the device of claim 1, wherein the cuffs are inserted into the nasal cavities completely with optional application of a lubricant gel.

11- The method of claim 9 for administering a continuous stabilized flow of oxygen supply by using the device of claim 1, wherein the pressure inside the cuffs is controlled by the air/fluid injected using the syringe.

12- The method of claim 9 for administering a continuous stabilized flow of oxygen supply by using the device of claim 1, wherein the pressure in claim 11 is high enough to achieve sealing but does exceed the capillary pressure of the nasal mucosa to avoid pressure necrosis and tissue damage.
