Effect of tube length on the buckling pressure of collapsible tubes

Computers in Biology and Medicine, 2021
The higher incidence of obstructive sleep apnea (OSA) in men than in women has been attributed to the upper airway being longer in men. The Starling resistor is the paradigm biomechanical model of upper airway collapse in OSA where a collapsible tube (representing the pharynx) is located between two rigid tubes (representing the nasal cavity and ...

A New Absorbable Pressure‐Equalizing Tube

Otolaryngology–Head and Neck Surgery, 2002
OBJECTIVEWe investigated pressure‐equalizing (PE) tubes made of biodegradable, absorbable material in an animal model.METHODSPE tubes, made of poly‐bis(ethylanate)phosphazene (PBE) were inserted in 55 ears of 28 Hartley guinea pigs, with survival times of 10, 30, and 60 days after tube insertion.

On Finite Bending of Pressurized Tubes

Journal of Applied Mechanics, 1959
Abstract A unified treatment is presented of two well-known problems which have until now been considered separately. The two problems are: (a) the linear problem of pure bending of curved tubes, and (b) the nonlinear problem of pure bending of straight tubes. In both problems the effect of uniform internal pressure is included.
