Abstract

A ventilation mask assist device is provided for use in anesthesia of a patient with an obstruction to provide an airtight seal when using a ventilation face mask. The ventilation mask assist device has an outer flap, an inner flap and a perioral extension extending through and connecting the outer flap and the inner flap. The perioral extension extends through a mouth of the patient and provides gaseous communication between the interior of the mouth and the ventilator mask. The outer flap is shaped to extend over the obstruction to cover cheeks and a chin of the patient. The edge of the conventional face mask contacts the outer flap and provides an airtight seal therebetween. The inner flap is shaped to cover the buccal side of the cheeks.

Claims

1. A ventilation mask assist device for use in anesthesia during a positive pressure ventilation of a patient with a facial obstruction, the ventilation mask assist device being used in combination with a ventilation face mask, the ventilation mask assist device comprising;

an outer flap which covers a chin and cheeks of a patient,

a perioral extension of the outer flap that continues into an oral cavity of the patient, and

an inner flap that extends from the perioral extension which extends along an inner surface of lips and the cheeks of a patient,

whereby the ventilation mask assist device when used in combination with the ventilation face mask provides an airtight seal during the positive pressure ventilation.

2. The ventilation mask assist device of claim 1 wherein the outer flap curves rearwardly and conforms to the shape of the face.

3. The ventilation mask assist device of claim 1 wherein the inner flap extends along an interior surface of the cheeks.

4. The ventilation mask assist device of claim 3 wherein the inner flap extends along the gum line.

5. The ventilation mask assist device of claim 1 wherein the outer flap defines a gap which corresponds to and extends laterally along an upper lip of the patient.

6. The ventilation mask assist device of claim 1 further comprising an oximeter having a sensor and a light source, one of the sensor and the light source being placed on the inner flap and the other of the sensor and the light source being placed on a corresponding position on the outer flap, the sensor measuring the amount of light received from the light source through the cheek of the patient, the oximeter calculating the amount of oxygen in the patient'"'"'s blood thereby.

7. The ventilation mask assist device of claim 1 adapted for use in combination with an oral airway.

8. The ventilation mask assist device of claim 1 manufactured from latex-free plastics.

9. The ventilation mask assist device of claim 1 manufactured from a clear plastic material.

10. The ventilation mask assist device of claim 1 wherein the perioral extension is manufactured from a hard plastic material to form a bite block.

11. A ventilation mask assist device for use in anesthesia during a positive pressure ventilation of a patient with a facial obstruction, the ventilation mask assist device being used in combination with a ventilation face mask, the ventilation mask assist device comprising;

an outer flap which outer flap curves rearwardly and conforms to the shape of the face to cover a chin and cheeks of a patient, the outer flap defining a gap which corresponds to and extends laterally along an upper lip of the patient,

a perioral extension of the outer flap that continues into an oral cavity of the patient, and

an inner flap that extends from the perioral extension which extends along an interior surface of the cheeks along the gum line of a patient,

whereby the ventilation mask assist device when used in combination with the ventilation face mask provides an airtight seal during the positive pressure ventilation.

12. The ventilation mask assist device of claim 11 further comprising an oximeter having a sensor and a light source, one of the sensor and the light source being placed on the inner flap and the other of the sensor and the light source being placed on a corresponding position on the outer flap, the sensor measuring the amount of light received from the light source through the cheek of the patient, the oximeter calculating the amount of oxygen in the patient'"'"'s blood thereby.

13. The ventilation mask assist device of claim 11 adapted for use in combination with an oral airway.

14. The ventilation mask assist device of claim 11 manufactured from latex-free plastics.

15. The ventilation mask assist device of claim 11 manufactured from a clear plastic material.

16. The ventilation mask assist device of claim 11 wherein the perioral extension is manufactured from a hard plastic material to form a bite block.
