Abstract

A gas ventilation mask includes an anesthesia nasal mask and a mouth mask defining respectively a nasal chamber and an oral chamber, detachably connected to one another so that the nasal mask and the mouth mask may be used either separately as a nasal mask or as a mouth mask, or as a combination nasal-mouth mask. Also provided is an anesthesia mask strap system having a first expandable strap portion having the ability to extend; second and third non-expandable strap sections fixed to ends of the first expandable strap section; and an adhesion section for fixing a length of the strap system when the second and third non-expandable strap sections are pulled to tension the expandable strap section.

Claims

1. A method of ventilating a patient, comprising:

applying a nasal mask over the patient'"'"'s nose while leaving the patient'"'"'s mouth uncovered, wherein the nasal mask having at least one opening, the at least one opening comprising a septum or valve therein, a closing of the septum or valve is actuated by pressure within the mask, and wherein the nasal mask further comprises a ventilation and/or oxygen port, wherein the at least one opening is adapted to receive a fluid passage of an oral chamber,

inserting the fluid passage of the oral chamber into the at least one opening, thereby causing the septum or valve to open and to allow fluid communication through the fluid passage between the oral chamber and the nasal mask, and

flowing a gas into the nasal mask through the ventilation and/or oxygen port to pressurize the nasal mask, and receiving the gas and exhalation of the patient from the nasal mask through the ventilation and/or oxygen port.

2. The method of claim 1, wherein the septum or valve is a flexible duckbill valve.

3. The method of claim 1, wherein the at least one opening is adapted to receive a fluid passage of any of a gas scavenger, a gas collector, a nebulizer port, a PEEP valve port, and an expiratory port and/or valve.

4. The method of claim 1, wherein inserting the fluid passage of the oral chamber into the at least one opening comprises inserting a proboscis tube of the oral chamber into the at least one opening.

5. The method of claim 1, comprising separating the oral chamber from the nasal mask to seal the septum or valve.

6. The method of claim 1, wherein the nasal mask comprises a ventilation port and an oxygen port, and wherein the oxygen port is separate from the ventilation port.

7. The method of claim 1, wherein flowing a gas into the nasal mask comprises providing the same pressure level at the nasal mask and the oral chamber.

8. The method of claim 1, wherein the fluid passage is formed of a flexible material.

9. The method of claim 8, further comprising moving the oral chamber relative to the nasal mask.

10. A method of ventilating a patient, comprising:

applying a nasal mask over the patient'"'"'s nose while leaving the patient'"'"'s mouth uncovered, wherein the nasal mask having at least one opening, the at least one opening comprising a septum or valve therein, a closing of the septum or valve is actuated by pressure within the mask, and wherein the nasal mask further comprises a ventilation and/or oxygen port, wherein the at least one opening is adapted to receive a fluid passage of an oral chamber;

flowing a gas into the nasal mask through the ventilation and/or oxygen port to pressurize the nasal mask; and

when the nasal mask is applied over the patient'"'"'s nose, inserting the fluid passage of the oral chamber into the at least one opening, thereby causing the septum or valve to open and to allow fluid communication through the fluid passage between the oral chamber and the nasal mask.

11. The method of claim 10, wherein inserting the fluid passage of the oral chamber into the at least one opening comprises inserting a proboscis tube of the oral chamber into the at least one opening.

12. The method of claim 10, wherein the nasal mask comprises a ventilation port and an oxygen port, and wherein the oxygen port is separate from the ventilation port.

13. The method of claim 10 wherein flowing a gas into the nasal mask comprises providing the same pressure level at the nasal mask and the oral chamber.
