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 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.
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 ...
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]
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.
Due to improved surgical instruments and technique, women with paramesonephric duct anomalies can have normal sexual relations. Through the use of Vecchietti and Mclndoe procedures, women can carry out their sexual activity. [9] On another note, many other surgical advances have tremendously improved fertility chances as well as obstetric outcomes.
Schematic of a Geiger counter using an "end window" tube for low-penetrating radiation. A loudspeaker is also used for indication. For alpha particles, low energy beta particles, and low energy X-rays, the usual form is a cylindrical end-window tube. This type has a window at one end covered in a thin material through which low-penetrating ...
Tube sinking, also known as free tube drawing, reduces the diameter of the tube without a mandrel inside the tube. The inner diameter is determined by the inner and outer diameter of the stock tube, the outer diameter of the final product, the length of the die landing, the amount of back tension, and the friction between the tube and the die.
