    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.

    摘要： An intubation scope assembly adapted to facilitate the positioning of an endotracheal tube in a patient comprising an electromagnetic or sound energy source which enters the vocal cords exteriorly of the neck of the patient with energy having a direction, wavelength and intensity capable of entering the trachea, substantially avoiding encompassing the entire pharynx and capable of being transmitted cephalad substantially between and/or around the vocal cords. 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： Various embodiments of the present invention include devices for use in determining the concentration of a tissue energy absorber (e.g., hemoglobin) in an individual's blood. In particular embodiments, the device includes a photometric device (e.g., a pulse oximeter) and an imaging device (e.g., an ultrasound imaging device or other suitable imaging device), and the device is adapted for: (A) using the photometric device to measure a change in mass of the tissue energy absorber within a particular volume of the individual's blood between a first point in time and a second point in time, the particular volume of blood being blood within a particular portion of at least one vascular structure, the vascular structure comprising at least one of the individual's vessels (e.g., at least one of the individual's arteries); (B) using an ultrasound imaging device to measure a change in interior volume, between the first point in time and the second point in time, of the particular portion of the vascular structure; and (C) using both the measured change in the mass of the tissue energy absorber, and the measured change in interior volume to determine at least an approximate blood total concentration of the tissue energy absorber within the individual's blood.

    摘要： A self-inflating resuscitation system formed from a self-inflating resuscitation bag and an exhalation indicator. In particular, the self-inflating resuscitation bag provides an exhalation indicator, which may be an audio or visual indicator, or both. The exhalation indicator enables a caregiver to more accurately determine whether a patient is being ventilated, unlike prior art self-inflating resuscitation bags, and helps to detect esophageal intubation in intubated patients or gastric trapping of gas in non-intubated patients undergoing positive pressure ventilation. In general, the device may be interposed between any source of positive pressure ventilation and any airway device to monitor exhalation as an indicator of adequacy of ventilation.

    摘要： Embodiments of the invention provide methods and devices for improved drainage systems and tubing. In one embodiment, a context-sensitive flow interrupter is provided that inhibits or facilitates flow of fluid when engaged with a mating holder. In another embodiment, outflow is optimized through control of the pressure in gas pockets in a tube, drainage tube or assembly. In one such embodiment, gas pockets are vented to inhibit excessive back-pressure or suction on an organ, vessel or cavity being drained. In another such embodiment, loops in the tubes are avoided by using a mechanical template in the form of a groove or peg assembly to thread the slack in the drainage tube to generate a monotonic gradient. In another embodiment, such as for active drainage systems, a bypass channel is provided that allows an applied vacuum to go around an obstruction created by the collection of fluid in an undrained dependent loop.
