Abstract

A bite block that is inserted into a patient'"'"'s mouth during an endoscopic diagnostic or surgical procedure that has a channel for receiving an endoscope or other surgical instrument through the patient'"'"'s mouth and additional channels transmitting a gas to the patient and transmitting expired gas from the patient.

Claims

1. An endoscopy bite block defining a front flange to overlap a patient'"'"'s mouth and an opening configured to be received between the patient'"'"'s lower and upper jaw and sized to provide access to the patient'"'"'s oral cavity, the opening defines i) a first channel member extending into the patient'"'"'s oral cavity and having a proximal end and a distal end, wherein the first channel member comprises a lower surface and an upper surface and the upper surface defines, ii) a second channel member coincident with the proximal end and the distal end and further defining a third surface substantially parallel to the lower surface and superior thereto and iii) a first support member positioned intermediate the first channel and the second channel and extending proximally from the front flange.

2. The bite block of claim 1, wherein the first channel member is oval-shaped.

3. The bite block of claim 1, wherein the second channel member comprises a first arcuate sub-channel and a second arcuate sub-channel immediately adjacent to the first arcuate sub-channel.

4. The bite block of claim 1, wherein the second channel member is sized to accommodate a tube for delivering a gas to the patient or monitoring the patient'"'"'s exhalation.

5. The bite block of claim 1, wherein a second support member extends proximally from the front flange.

6. The bite block of claim 1 further comprising a second opening adjacent the first channel sized to accommodate a finger.

7. The bite block of claim 6, wherein the first channel comprises lateral cut-out extending from the distal end and toward the proximal end.

8. The bite block of claim 1, wherein the second channel member is sized to accommodate a tube for delivery a gas to the patient and a tube for monitoring the patient'"'"'s exhalation.

9. A kit for performing an endoscopic procedure comprising:

a. A bite block defining a front flange to overlap a patient'"'"'s mouth and an opening configured to be received between the patient'"'"'s lower and upper jaw and for communicating with the patient'"'"'s oral cavity, the opening defines i) a first channel member extending into the patient'"'"'s oral cavity and having a proximal end and a distal end, wherein the first channel member comprises a lower surface and an upper surface, ii) a second channel member coincident with the proximal end and the distal end and further defining a third surface substantially parallel to the lower surface and superior thereto, a first support member positioned intermediate the first channel and the second channel and extending proximally from the front flange; and

b. a cannula having a first port for receiving a first gas, a second port for transmitting a second gas, a third port for delivering the first gas to the patient and a fourth port for receiving the second gas from the patient, wherein the second channel member is sized to accommodate the third and fourth ports.

10. An endoscopy bite block defining a front flange to overlap a patient'"'"'s mouth and an opening configured to be received between the patient'"'"'s lower and upper jaw and sized to provide access to the patient'"'"'s oral cavity, the opening defines i) a first channel member extending into the patient'"'"'s oral cavity and having a proximal end and a distal end, wherein the first channel member comprises a lower surface and an upper surface and the upper surface defines, ii) a second channel member defining a third surface substantially parallel to the lower surface and superior thereto and iii) a first support member positioned intermediate the first channel and the second channel and extending proximally from the front flange.

11. The bite block of claim 10, wherein the second channel member is sized to accommodate a tube for delivery a gas to the patient and a tube for monitoring the patient'"'"'s exhalation.

12. The bite block of claim 10, wherein the first channel member is oval-shaped.

13. The bite block of claim 10, wherein the second channel member comprises a first arcuate sub-channel and a second arcuate sub-channel immediately adjacent to the first arcuate sub-channel.

14. The bite block of claim 10, wherein a second support member extends proximally from the front flange.

15. The bite block of claim 10 further comprising a second opening adjacent the first channel sized to accommodate a finger.

16. The bite block of claim 15, wherein the first channel comprises lateral cut-out extending from the distal end and toward the proximal end.

17. The bite block of claim 10, wherein the second channel member is sized to accommodate a tube for delivering a gas to the patient or monitoring the patient'"'"'s exhalation.
