Benefits of technology

[0009] In short, this invention provides a means for a procedural physician outside the practice of anesthesiology to provide sedation and/or pain relief to patients. The automation provided by the invention compensates for lack of clear standards of practice for non-anesthetists to guide

Problems solved by technology

Further, patients often require assistance in maintaining a patient airway, and positive pressure ventilation may be required becaus

first embodiment

[0109]FIGS. 19 and 20 show a bite block 74, which, in one example, is used with the cannula assembly 145 of FIGS. 1-18. A bite block, in one example, is used on a patient during an upper-gastrointestinal endoscopic medical procedure. The bite block has a bite-block body, which is inserted into the mouth of the patient. The bite-block body has a through passageway for insertion of an endoscope therethrough. The patient bites down on the bite-block body instead of on the endoscope.

[0110] A first expression of the embodiment of FIGS. 19 and 20 is for a bite block 74 including a bite-block body 76 adapted for insertion into the mouth of a patient. The bite-block body 76 includes a through passageway 78 and includes an air sampling passageway 80 spaced apart from the through passageway 78. The through passageway 78 is adapted for receiving therethrough a medical instrument 82 (only an unhatched portion of which is shown in FIG. 20). The air sampling passageway 80 has an inlet 84 disposed...

second embodiment

[0112]FIG. 21 shows a bite block. An expression of the embodiment of FIG. 21 is for a bite block assembly 96 including a bite-block body 98 and an air sampling tube 102. The bite-block body 98 is adapted for insertion into the mouth of a patient and includes a through passageway 104 adapted for receiving therethrough a medical instrument 106 (only a portion of which is shown). The air sampling tube 102 is attached to the bite-block body 98, has an inlet 108 disposed to receive exhaled air from the patient when the bite-block body 98 is inserted into the mouth of the patient and has an outlet 112 attached or attachable to a respiratory gas sampling port of a cannula.

[0113] In one variation of the embodiment of FIG. 21, the air sampling tube 102 is at least partially disposed within the through passageway 104. In one construction, the air sampling tube 102 is adhesively attached to the bite-block body 98. In one employment, the outlet 112 of the air sampling tube 102 is adapted for in...

third embodiment

[0114]FIG. 22 shows a bite block. An expression of the embodiment of FIG. 22 is for a bite block assembly 122 including a bite-block body 124 and an air sampling tube 126. The bite-block body 124 is adapted for insertion into the mouth of a patient. The bite-block body 124 includes a through passageway 128 adapted for receiving therethrough a medical instrument 132 (only a portion of which is shown) and includes an air sampling passageway 134. The air sampling tube 126 is at least partially disposed within the air sampling passageway 134, has an inlet 136 disposed to receive exhaled air from the patient when the bite-block body 124 is inserted into the mouth of the patient, and has an outlet 138 attached or attachable to a respiratory gas sampling port of a cannula. In one variation, the outlet 138 of the air sampling tube 126 is adapted for indirect attachment to the respiratory gas sampling port of the cannula through a connector tube 148.

Abstract

Disclosed is an oxygen delivery device for regulating the flow of oxygen from an oxygen source to a respiratory cannula located on the face of a patient. A host controller coupled to the oxygen delivery device accepts an input from a medical monitor relating to the blood oxygen saturation percentage of the patient. The host controller then regulates the rate of oxygen supplied to the patient based in part upon the blood oxygen saturation percentage of the patient. A high rate of oxygen is supplied to the patient when the controller detects a blood oxygen saturation level below a predetermined percentage and a low rate of oxygen is supplied when the controller detects a blood oxygen saturation level above a predetermined percentage in an order to minimize wasted oxygen.
