| Ryle's tube | A thin rubber tube, with about the lumen of a no. 8 catheter, and an olive-tipped extremity, used in the giving of a test meal. (05 Mar 2000) |

| Miller-Abbott tube | A tube with two lumens, one ending in a small collapsible balloon and the other in a metallic tip with numerous perforations; used for intestinal decompression. Synonym: Abbott's tube. (05 Mar 2000) |
| photomultiplier tube | A detector which amplifies a signal (by as much as 106) of electromagnetic radiation by an acceleration of electrons released from a photocathode through a series of dynodes; as each electron strikes a dynode stage, 3 to 4 electrons are liberated and accelerated to the subsequent dynode. (05 Mar 2000) |
| Wangensteen tube | A modified siphon that maintains constant negative pressure, used with a duodenal tube for the relief of gastric and intestinal distention. Synonym: Wangensteen tube. (05 Mar 2000) |
| molybdenum target tube | An X-ray tube with an anode surface made of molybdenum instead of tungsten, used in mammography. (05 Mar 2000) |
| water tube | <zoology> One of a system of tubular excretory organs having external openings, found in many invertebrates. They are believed to be analogous in function to the kidneys of vertebrates. Source: Websters Dictionary (01 Mar 1998) |
| pitot's tube | <physics> A bent tube used to determine the velocity of running water, by placing the curved end under water, and observing the height to which the fluid rises in the tube; a kind of current meter. Source: Websters Dictionary (01 Mar 1998) |
| Pitot tube | A stationary L-shaped tube inserted in a fluid stream, with its opening upstream, and used for measuring the velocity of fluid movement at that point in terms of the pressure developed in the tube by the fluid impinging on it, compared to a second tube opening laterally or downstream. (05 Mar 2000) |
| Moss tube | A triple-lumen, nasogastric, feeding-decompression tube, that utilises a gastric balloon to occlude cardioesophageal junction, with simultaneous oesophageal aspiration and intragastric feeding, a double-lumen, gastric lavage tube, that provides continuous delivery of saline via a small bore, with simultaneous aspiration of fluid and some particles via a large bore. (05 Mar 2000) |
| mucosa of auditory tube | The lining coat of the auditory tube. Synonym: tunica mucosa tubae auditivae. (05 Mar 2000) |
| mucosa of uterine tube | The mucous layer of the uterine tube. Synonym: tunica mucosa tubae uterinae. (05 Mar 2000) |
| mucous glands of auditory tube | Glands located principally near the pharyngeal end of the auditory tube. Synonym: glandulae tubariae, glands of auditory tube, glands of eustachian tube. (05 Mar 2000) |
| muscular coat of uterine tube | Muscular layer of the wall of the uterine tube. Synonym: tunica muscularis tubae uterinae. (05 Mar 2000) |
| Coolidge tube | An X-ray tube, in which the cathode consists of a tungsten wire spiral surrounded by a focusing cup; the tungsten spiral is heated by an electric current; the quantity and quality of the X-rays so generated are regulated by varying the temperature of the cathode and the voltage between cathode and anode. (05 Mar 2000) |
| Crookes-Hittorf tube | A simple evacuated tube containing a cathode, that emitted X-rays from the glass envelope when a current was passed through it; the type used by Roentgen to discover X-rays. (05 Mar 2000) |
