Dobhoff tube, which is a small bore NG tube with a weight at the end intended to pull it by gravity during insertion. The name "Dobhoff" refers to its inventors, surgeons Dr. Robert Dobbie and Dr. James Hoffmeister, who invented the tube in 1975.
A gastric feeding tube (G-tube or "button") is a tube inserted through a small incision in the abdomen into the stomach and is used for long-term enteral nutrition. One type is the percutaneous endoscopic gastrostomy (PEG) tube which is placed endoscopically. The position of the endoscope can be visualized on the outside of the person's abdomen ...
A Miller–Abbott tube is a tube used to treat obstructions in the small intestine through intubation. [1] It was developed in 1934 by William Osler Abbott and Thomas Grier Miller . The device is around 3 metres (9.8 ft) [ 2 ] long and has a distal balloon at one end.
Placement of a weighted feeding tube (e.g. Dobhoff) into the duodenum after previous attempts without fluoroscopy have failed; Discography, an invasive diagnostic procedure for evaluation for intervertebral disc pathology. [10] [11]
In an ideal tube, the wavelength of the sound produced is directly proportional to the length of the tube. A tube which is open at one end and closed at the other produces sound with a wavelength equal to four times the length of the tube. A tube which is open at both ends produces sound whose wavelength is just twice the length of the tube.
A tube, or tubing, is a long hollow cylinder used for moving fluids (liquids or gases) or to protect electrical or optical cables and wires. The terms " pipe " and "tube" are almost interchangeable, although minor distinctions exist — generally, a tube has tighter engineering requirements than a pipe.
Chest tube have an end hole (proximal, toward the patient) and a series of side holes. The number of side holes is generally 6 on most chest tubes. The length of tube that has side holes is the effective drainage length (EDL). In chest tubes designed for pediatric heart surgery, the EDL is shorter, generally by only having 4 side holes. [17]
It consists of a cuffed, double-lumen tube that is inserted through the patient's mouth to secure an airway and enable ventilation.Generally, the distal tube (tube two, clear) enters the esophagus, where the cuff is inflated and ventilation is provided through the proximal tube (tube one, blue) which opens at the level of the larynx.
