ENDOTRACHEAL TUBE HOLDING DEVICE WITH BITE BLOCK

摘要

A device (30) for holding an endotracheal tube (44, 372) to a patient is disclosed, comprising: a track (32) configured to fit adjacent a lip on a patient's face, the track having a face contacting side (34), an exposed side (36) opposite the face contacting side, and a pair of opposite ends (38); a tube holder (40, 220, 270, 280, 290, 320, 330, 350, 360, 366, 380, 400, 520, 550, 570) coupled to and slidable along the track between the opposite ends; a positioning mechanism (42) that is releasably lockable to allow selective lateral repositioning of the tube holder and an endotracheal tube held thereby along the track and to retain the tube holder at a selected position along the track; a bite block (46, 222, 272, 282, 292, 322, 332, 352, 362, 368, 382, 402, 420, 440, 460, 480, 500, 522, 552, 572) carried by the tube holder and slidable therewith along the track, the bite block having a tubular wall (120, 224, 302, 388, 422, 442, 462, 482, 502, 528, 586), a central opening (122) along a length ot the bite block, an interior wall surface (140, 240, 300, 434, 452, 472), and a pair of opposite open ends (114, 126, 386, 526), the bite block positioned spaced vertically from the track and one of the opposite ends being a working end (126, 386, 526) portion that extends in the direction of and further beyond the face contacting side of the track; and an accessory line channel (138, 236, 238, 354, 428, 432, 454, 468, 488, 508, 512) positioned between the interior wall surface and an endotracheal tube that extends through the central opening. A bite block as above for an endotracheal tube is also disclosed, wherein the accessory line channel is further formed by a wall segment (298, 470, 490, 510, 536) that is recessed into the interior wall surface, the wall segment being thinner than a thickness of the tubular wall adjacent the wall segment.
