Abstract
A toroid shaped mouthpiece that is inserted into a patient's mouth between the patient's gums and cheeks. The mouthpiece is particularly configured to sustain an oral space through which the patient can breathe from an anesthesia face mask. With the anesthesia face mask in place over the patient's nose and mouth cavities, the mask generates a good seal with the patient's cheeks because the mouthpiece insures that the cheeks will remain flushed out against the mask. This is particularly advantageous in the case of edentulous patients.
Claims7
A mouthpiece for a patient to aid in maintaining a seal between a face mask and cheeks of a patient upon exposing that patient to a gaseous anesthesia through use of said face mask, said mouthpiece comprising:
- a substantially normally curved, flexible one-piece member being generally elliptically-shaped when flexed into a generally flat configuration and sized to be received in a patient's mouth between the patient's jaw, lips and cheeks and underlie the patient's lips and cheeks,
- said member having a centrally elliptically-shaped oral port and having upper and lower jaw sections connected one with the other by side sections,
- said member having a major axis which intersects said mouthpiece's side sections and a minor axis which intersects said mouthpiece's jaw sections when said unit is in said flattened state, said jaw and side sections having cross-sectional areas as measured along said minor and major axis, respectively, said jaw sections' cross-sectional areas being substantially circular from which that cross-sectional area diverges to a substantially larger, thicker elliptical cross-sectional area at said side sections,
- said jaw sections' cross-sectional areas being adapted to be situated entirely between the gums and the lips and cheeks of the patient and said side sections being adapted to be situated between the patient's gums and cheeks, and
- said member having sufficient thickness and having sufficient hardness such that, when inserted in the patient's mouth, the patient's lips are held in spaced-apart relationship to facilitate the flow of gas into and out of the patient's mouth and the patient's cheeks are urged outwardly to cooperate with the periphery of an anesthesia face mask in order to maintain a seal between the face mask and the patient's cheek areas as desired by the attenting physician during breathing of that patient through the face mask.

A method of anesthetizing a patient through use of a gaseous anesthesia, said method comprising the steps of
- (a) providing a mouthpiece for the patient to aid in maintaining a seal between a face mask and the cheeks of a patient upon that patient being exposed to gaseous anesthesia through the use of said face mask, said mouthpiece comprising:
- a substantially normally curved flexible one-piece member being generally elliptically-shaped when flexed into a generally flat configuration and sized to be received in a patient's mouth between the patient's jaw, lips and cheeks and underlie the patient's lips and cheeks,
- said member having a centrally elliptically-shaped oral port and having upper and lower jaw sections connected one with the other by side sections,
- said member having a major axis which intersects said mouthpiece's side sections and a minor axis which intersects said mouthpiece's jaw sections when said unit is in said flattened state, said jaw and side sections having cross-sectional areas as measured along said minor and major axis, respectively, said jaw sections' cross-sectional areas being substantially circular from which that cross-sectional area diverges to a substantially larger, thicker elliptical cross-sectional area at said side sections,
- said jaw sections' cross-sectional areas being adapted to be situated entirely between the gums and the lips and cheeks of the patient and said side sections being adapted to be situated between the patient's gums and cheeks,
- said member having sufficient thickness and having sufficient hardness such that, when inserted within a patient's mouth, the patient's lips are held in spaced-apart relationship to facilitate the flow of gas into and out of the patient's mouth and the patient's cheeks are urged outwardly to cooperate with the periphery of an anesthesia face mask in order to maintain a seal between the face mask and the patient's cheek areas as desired by the attending physician during breathing of that patient through the face mask,
- (b) inserting said mouthpiece into the patient's mouth so said mouthpiece's entire jaw sections are between the patient's lips and gums and cheeks such that the lips are held in spaced-apart relationship and said mouthpiece's side sections are between the patient's gums and cheeks such that said cheeks are urged away from said gums,
- (c) thereafter placing a face mask on the exterior of the patient's face so that said mask's periphery on the patient's cheeks is juxtaposed at least to the side sections of said mouthpiece located in said patient's mouth, and
- (d) thereafter selectively providing gaseous anesthesia to said face mask.
