Abstract
There is provided herein, a bite block (100) comprising an insertion channel (134) and an airway channel (132) wherein the airway channel is adapted to receive exhaled breath and wherein the first insert channel is adapted to pass a medical instrument. There is provided herein, a bite block comprising an oral insert channel, wherein a portion of said channel opens into a cavity (142) adapted to slidably receive an oral prong (270) the oral insert channel is adapted to receive exhaled breath.
Claims18
A bite block comprising:
- a front plate configured to lodge against a patient's lips and forming a first opening and a second opening;
- and
- a mouthpiece configured for insertion into the patient's mouth, the mouthpiece comprising:
- an airway channel configured to receive exhaled breath from the patient and to allow exhaled breath and inhaled air to flow freely back and forth along the channel when in use, the airway channel extending from the second opening of the front plate to an airway channel end;
- an insertion channel extending away from the first opening to an end of the insertion channel, the insertion channel being formed by a wall having an inner surface and an external surface, wherein the insertion channel is configured to pass a medical instrument through the first opening and within the inner surface of the wall, wherein the insertion channel is positioned below a lower portion of the airway channel;
- a cavity orthogonal to and extending away from an upper portion of the airway channel and terminating in the upper portion of the airway channel at a location positioned between the second opening and the airway channel end;
- and
- an oxygen channel extending along at least a part of the external surface of the wall, wherein the external surface of the wall defines at least a portion of an interior surface of the oxygen channel and a portion of an exterior wall of the mouthpiece, wherein the wall completely separates the oxygen channel from the insertion channel such that there is no fluid communication between the oxygen channel and the insertion channel along the wall, and wherein the oxygen channel is configured to deliver oxygen therethrough,
- wherein the airway channel is formed external to the inner surface of the wall, such that the airway channel is separated from the insertion channel and the oxygen channel, and wherein the airway channel is configured to protrude further into the patient's mouth than the oxygen channel and the insertion channel when in use, such that a distance is maintained between the airway channel end and the end of the insertion channel.
6 more elements
A system for sampling breath, the system comprising a bite block comprising:
- a front plate configured to lodge against a patient's lips;
- and
- a mouthpiece configured for insertion into the patient's mouth, wherein the mouthpiece comprises:
- an airway channel configured to receive exhaled breath from a patient and to allow exhaled breath and inhaled air to flow freely back and forth along the airway channel when in use;
- and terminating in a duct opening formed through the front plate;
- an insertion channel extending from a first opening of the insertion channel formed through the front plate along the mouthpiece, the insertion channel formed by a wall having an inner surface and an external surface, wherein the insertion channel is configured to pass a medical instrument within the inner surface of the wall;
- an oxygen channel, wherein the oxygen channel is formed adjacent to the insertion channel such that the oxygen channel extends along at least a part of the external surface of the wall of the insertion channel, wherein the external surface defines at least a portion of an interior surface of the oxygen channel and a portion of an exterior wall of the mouthpiece, wherein the wall completely separates the oxygen channel from the insertion channel such that there is no fluid communication between the oxygen channel and the insertion channel along the wall the oxygen channel is configured to deliver oxygen therethrough, wherein the airway channel is configured to protrude farther into the patient's mouth than the oxygen channel and the insertion channel when in use, such that a substantial distance is maintained between respective internal ends of the airway channel and the insertion channel.
