Benefits of technology

[0005] It is known to deliver IV sedation drugs to a patient from a drug-delivery cassette assembly using a peristaltic pump wherein the cassette assembly and pump are attached to the procedure room unit.

Problems solved by technology

Further, patients often require assistance in maintaining a patient airway, and positive pressure ventilation may be required because of depressed spontaneous ventilation or drug-induced depression of neuromuscular function, cardiovascular function may be impaired.

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 apparatus constructed from an oxygen delivery manifold, a respiratory cannula, and a host controller. The host controller contains an oxygen delivery program and accepts a respiration input regarding whether the patient is inhaling or exhaling, and whether the patient is breathing orally or nasally. The oxygen delivery program regulates the flow rate of oxygen based in part upon the respiration input provided. A first rates is used when the patient is inhaling and exhaling orally, a second rate is used when the patient is inhaling nasally, and a third rate is used when the patient is exhaling nasally.
