摘要： A diagnostic monitor checks the carbon dioxide (CO.sub.2) content of a gas exiting a patient during endotracheal or esophageal intubation. A plurality of composition portions substantially change color in response to exposure to the carbon dioxide. The composition portions change color in response to different times of exposure to carbon dioxide. A magnifying or condensing lens may be positioned on the monitor to enhance viewing of the color change. The monitor may advantageously be made as part of an intubation system through which the gases from a patient exit the patient. The differences in time of exposure needed to cause the color change may be accomplished by using semipermeable membranes having differing thicknesses, CO.sub.2 permeabilities, and/or surface areas with each membrane corresponding to a particular one of the composition portions.

A suitable sensor for the energy emitted by such source comprises a stylet assembly, the distal end of which can detect or collect the energy transmitted between and/or around the vocal cords and the proximal end of which can monitor the detected or collected energy to thereby locate the vocal cords for positioning an endotracheal tube therebetween. A system and method of intubating a patient with the foregoing assembly are also disclosed.

摘要： The subject invention pertains to a system for imaging the human airway having highly advantageous optical, mechanical, ergonomical and physical characteristics. In a specific embodiment, the human airway can be imaged during the intubation procedure. The subject imaging scopes can incorporate a malleable stylet which retains its shape when bent, in order to facilitate intubation of a patient. In a preferred embodiment, a solid metal stylet, for example, a conventional endotracheal tube stylet, can be utilized. In a specific embodiment the subject intubation scope allows for a user to utilize conventional techniques for the insertion of an endotracheal tube, reducing the training needed for use of the subject intubation scope. Preferably, the subject imaging scopes also incorporate at least one illumination fiber to convey light to the distal tip of the subject imaging scopes, for illumination of the objects to be imaged.

摘要： The subject invention pertains to a system for imaging the human airway having highly advantageous optical and physical characteristics. In a specific embodiment, the human airway can be imaged during the intubation procedure. The excellent characteristics of the imaging system of the subject invention result, in part, from the use of plastic optic fibers. Plastic fibers are more robust than the glass optical fibers used in currently available imaging systems, and are therefore capable of being bent and/or twisted with less concern of breakage. In addition, the lower costs of plastic fibers enables scopes of the subject invention, in a specific embodiment, to be manufactured for single patient use thereby eliminating the requirement for cleaning, special care, the maintenance of expensive inventory, and most importantly eliminating the opportunity for cross contamination between patients. A further aspect of the subject invention concerns a novel sheath which covers the portion of the imaging system which enters the patient. In this case, the sheath and its optional associated fiber optic illumination is disposable after each use.

摘要： Disclosed is an intubation imaging stylet for intubating a patient by use in a tube/imaging stylet combination, said imaging stylet comprising: a malleable stylet having a longitudinal axis and a proximal end and a distal end; a flexible image guide having a longitudinal axis and a proximal end and a distal end, said image guide being connected to said stylet such that a portion of said image guide runs parallel to a portion of said stylet along the longitudinal axis of said stylet and such that the distal end of said image guide is co-extensive with the distal end of said stylet; and at least one flexible illumination fiber having a proximal end and a distal end, said illumination fiber being connected to said stylet such that a portion of said illumination fiber runs parallel to a portion of said stylet along the longitudinal axis of said stylet and such that the distal end of said illumination fiber is co-extensive with the distal end of said stylet; such that in use, said imaging stylet is disposed within a tube for intubating a patient thereby forming an imaging stylet/tube combination which in use is held by gripping the tube in a pen-like fashion. The imaging stylet/tube combination is thus in use held in one hand, freeing the other hand of the user for other tasks if necessary, as well as permitting intubation in the conventional manner. To facilitate this, the center of gravity of the imaging stylet/tube combination is located in essentially the same location along the tube as with a conventional stylet/tube combination.
