| feeding tube n. A flexible tube that is inserted through the pharynx and into the esophagus and stomach and through which liquid food is passed. |
feeding tube,
a tube for introducing fluids of high caloric value into the stomach. See also tube feeding.
tube
a hollow cylindrical organ or instrument.
chest tube
one or more tubes inserted into the pleural space to provide relief from either pneumothorax or accumulations of fluid within the thoracic cavity and to allow for re-expansion of the lung.
drainage tube
a tube used in surgery to facilitate escape of fluids. See also drain (2).
endobronchial tube
a double-lumen tube inserted into the bronchus of one lung, permitting complete deflation of the other lung; used in anesthesia and thoracic surgery.
eustachian tube
feeding tube
one for administering food into the alimentary tract. See also enterostomy tube, jejunostomy tube, tube gastrostomy, nasoesophageal tube (below).
fermentation tube
a U-shaped tube with one end closed, for determining gas production by bacteria. Called also Durham tube.
Levin tube
a gastroduodenal catheter of sufficiently small caliber to permit transnasal passage.
nasoesophageal tube
a feeding tube introduced through the nares and nasal cavity, then into the esophagus. Used in enteral feeding of dogs and cats.
otopharyngeal tube
auditory tube.
pharyngostomy tube
see pharyngostomy intubation.
photomultiplier tube
a vacuum tube that produces an electric current proportional to the intensity of light falling on its photocathode; it is sensitive enough to detect single photons.
tube rating chart
provided by the manufacturer and containing the specifications for the safe operating limits of the x-ray tube in terms of kilovolt peak, milliamps and time.
stomach tube
a flexible tube used for introducing food, medication, or other material directly into the stomach, or for removal of undesirable contents from the stomach. It can be passed into the stomach via the nose or mouth. Passage via the mouth requires the protection of a mouth speculum.
suction drainage tube
see suction drainage.
test tube
a tube of thin glass, closed at one end; used in chemical tests and other laboratory procedures.
thoracostomy tube
one inserted through an opening in the chest wall for application of suction to the pleural cavity to facilitate re-expansion of the lung in spontaneous pneumothorax. See also chest tube (above).
