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.

Claims

1-27. -27. (canceled)

28. A bite block comprising a mouthpiece, wherein said mouthpiece comprises an airway channel and an insertion channel extending essentially along the length of said mouthpiece,

wherein said insertion channel is configured to pass a medical instrument and to allow substantially free flow of breath;

and

wherein said airway channel is configured to allow exhaled breath and inhaled air to flow substantially freely back and forth along said airway channel, wherein said airway channel is further configured to receive an oral prong, wherein said oral prong is configured to sample breath from said airway channel for the purpose of capnographic measurements.

29. The bite block according to claim 28, wherein said airway channel is formed by a first substantially curved surface which slopes upwards in the direction of the roof of the mouth when said mouthpiece is inserted in a patient'"'"'s mouth, and a second substantially curved surface, which is configured to provide a biting surface for the patient'"'"'s upper teeth.

30. The bite block according to claim 28, wherein said oral prong comprises an opening configured to face towards the flow of breath flowing along said airway channel.

31. The bite block according to claim 28, wherein a portion of said airway channel opens into a cavity configured to receive said oral prong, configured.

32. The bite block according to claim 31, wherein said cavity is further configured to allow relative lateral movement between the oral prong and said cavity, while maintaining the opening of said oral prong facing towards the flow of breath flowing along said airway channel.

33. The bite block according to claim 32, wherein said airway channel is adapted to allow exhaled breath and inhaled air to flow substantially freely back and forth along said airway channel through a duct.

34. The bite block according to claim 33, wherein said duct is further adapted to enable a viewer to view the position of said oral prong functionally connected to said bite block.

35. The bite block according to claim 28, wherein said airway channel is configured to extend deeper into the mouth of a patient compared to said insertion channel.

36. The bite block according to claim 28, further comprises an oxygen channel located in proximity to said insertion channel, wherein said oxygen channel comprises an aperture configured to direct oxygen towards the inside of the mouth of a patient.

37. The bite block according to claim 36, wherein said aperture is located in the insertion channel.

38. The bite block according to claim 36, wherein said airway channel is configured to protrude further into the back of the mouth relative to said oxygen channel.

39. The bite block according to claim 36, configured to reduce the flow of oxygen from said oxygen channel into said airway channel, such that the oxygen pressure is configured to be lower than the opposing pressure created by the exhaled breath, so that the exhaled breath can push back out of the mouth the oxygen, and at least partially prevent oxygen from reaching the airway channel opening and consequently diluting the sampled breath.

40. A system for sampling breath, the system comprising:

a bite block comprising a mouthpiece, wherein said mouthpiece comprises an airway channel and an insertion channel extending essentially along the length of said mouthpiece and an oxygen channel located in proximity to said insertion channel, wherein said insertion channel is configured to pass a medical instrument and to allow substantially free flow of breath;

wherein said airway channel is configured to allow exhaled breath and inhaled air to flow substantially freely back and forth along said airway channel, wherein said airway channel is further configured to receive an oral prong configured to sample breath from said airway channel for the purpose of capnographic measurements; and

wherein said oxygen channel comprises an aperture configured to direct oxygen towards the inside of the mouth of a patient;

and

a valve configured to regulate oxygen delivery to said oxygen channel.

41. The system according to claim 40, wherein said airway channel is formed by a first substantially curved surface which slopes upwards in the direction of the roof of the mouth when said mouthpiece is inserted in a patient'"'"'s mouth, and a second substantially curved surface, which is configured to provide a biting surface for the patient'"'"'s upper teeth.

42. The system according to claim 40, wherein said oral prong comprises an opening configured to face towards the flow of breath flowing along said airway channel.

43. The system according to claim 40, wherein a portion of said airway channel opens into a cavity configured to receive said oral prong.

44. The system according to claim 43, wherein said cavity is further configured to allow relative lateral movement between the oral prong and said cavity, while maintaining the opening of said oral prong facing towards the flow of breath flowing along said airway channel.

45. The system according to claim 40, wherein said airway channel is configured to extend deeper into the mouth of a patient compared to said insertion channel.

46. The system according to claim 40, wherein said aperture of said oxygen channel is located in the insertion channel.

47. The system according to claim 40, wherein said airway channel is configured to protrude further into the back of the mouth relative to said oxygen channel.
