nasotracheal tube  an endotracheal tube that passes through the nose.

neural tube  the epithelial tube developed from the neural plate and forming the central nervous system of the embryo.

orotracheal tube  an endotracheal tube that passes through the mouth.

Orotracheal tube.

otopharyngeal tube , pharyngotympanic tube auditory t.

Sengstaken-Blakemore tube  a multilumen tube used for tamponade of bleeding esophageal varices.

Sengstaken-Blakemore tube for esophagogastric tamponade.

stomach tube  a tube for feeding or for stomach irrigation; the most common kind is the nasogastric tube.

test tube  a tube of thin glass, closed at one end; used in chemical tests and other laboratory procedures.

tracheal tube  endotracheal t.

tracheostomy tube  a curved endotracheal tube that is inserted into the trachea through a tracheostomy.

uterine tube  fallopian tube; a slender tube extending from the uterus toward the ovary on the same side, for passage of oocytes to the cavity of the uterus and the usual site of fertilization.

Uterine, or fallopian, tube.

Wangensteen tube  a small nasogastric tube connected with a special suction apparatus to maintain gastric and duodenal decompression.

x-ray tube  a vacuum tube used for the production of x-rays; when a suitable current is applied, high-speed electrons travel from the cathode to the anode, where they are suddenly arrested, giving rise to x-rays.

endotracheal tube

n.

A tube inserted into the trachea to provide a passageway for air. Also called tracheal tube.

---

Endotracheal tube

A metal or plastic tube inserted in the windpipe which may be attached to a ventilator. It also may be used to deliver medications such as surfactant.

endotracheal tube,

a large-bore catheter inserted through the mouth or nose and into the trachea to a point above the bifurcation of the trachea. It is used for delivering oxygen under pressure when ventilation must be totally controlled and in general anesthetic procedures. See also endotracheal intubation.

tube,

n a hollow cylindrical structure.

tube, buccal,

n a section of tubing attached to the buccal side of a molar band in a horizontal position, serving as an attachment for the labial arch wire, which slides into the tube.

tube, Coolidge,

n.pr a radiographic tube in which the gas pressure is purposely made so low that it plays no role in the operation of the tube, the operation of which depends on the emission of electrons by the heated filament of the cathode. See also radiographic tube, Coolidge.

tube, discharge,

n a vacuum tube in which a high-voltage electric current is discharged (e.g., a radiographic tube).

tube, endotracheal,

n a plastic tube inserted into the trachea to permit the passage of air to and from the lungs. Tubes are available in varying diameters, depending on the size and age of the patient.

tube, horizontal,

n a metal tube attachment that is placed in a horizontal position on the buccal surface of each anchor molar tooth to allow for the insertion of the labial arch wire.

tube, intubation,

n a tube for insertion into the larynx through the oral cavity.

tube, line focus,

n a radiographic tube in which the target face is about 20 inches (50 cm) from the cathode face. The focal spot is rectangular, with the length approximately three times the width. The acute angle provides an effective focal spot area approximately square and a fraction of the actual area in size.

tube, nasogastric

n a plastic tube inserted through the nose, down the esophagus, and into the stomach. It is used to remove the stomach's contents or to pass food directly to the stomach. Also known as an
NG tube.

tube, protective, housing,

n a radiographic tube enclosure that provides radiation protection.

tube, protective, housing, diagnostic,

n a tube housing that reduces the leakage of radiation to, at most, 0.10 r/hr at a distance of 1 mm from the tube target when the tube is operating at its maximal continuous rated voltage.

tube, protective, housing, therapeutic,

n a tube housing that reduces the leakage of radiation to, at most, 1 r/hr at a distance of 1 m from the tube target when the tube is operating at its maximal continuous rated current for the maximal rated voltage.

tube, right-angle,

n a radiographic tube in which the target is at right angles to the cathode.

tube tooth,

n See tooth, tube.

tube, vertical,

n an attachment that is usually placed on the lingual surface of the anchor band to allow for the insertion of the lingual wire.

tube, radiographic,

n See radiographic tube.

Cole-pattern endotracheal tube

one with a tapered shape with no cuff; designed to be fitted with a wider shoulder at the larynx and narrow end in the trachea. Used in horses.

endotracheal intubation

an airway catheter inserted in the trachea during endotracheal intubation to assure patency of the upper airway by allowing for removal of secretions and maintenance of an adequate air passage. In animals, endotracheal intubation is usually accomplished through the mouth using an orotracheal tube.

nasal endotracheal tube

an endotracheal tube designed to be passed through the nasal cavity into the trachea. It usually has a thin wall.

reinforced endotracheal tube

a spiral wire or nylon strip is incorporated into the wall to reduce the risk of collapse or kinking.

endotracheal tube

a variety of endotracheal tubes is available. The tubes are almost always 'cuffed' to allow for their use with a mechanical ventilator. The cuff is a rubber balloon-like device that fits over the lower end of the tube. It is attached to a narrow tube that extends outside the body and allows for inflation of the cuff. Once the cuff is inflated there is no flow of air through the trachea other than that going through the endotracheal tube.
