Urinary catheters (drainage tubes) are in widespread use. The most common type of long-term catheter is the Foley, which is made from natural or synthetic rubber. Foley catheters are passed into the bladder via the urethra or the suprapubic puncture

Debris build-up within the bladder is one of the main problems encountered by patients undergoing long term catheterization. One of the methods of ameliorating this is to wash out the bladder at regular intervals. In this paper, an alternative method

Mathematical modeling of the dynamic behavior of vulcanizates is reviewed with the emphasis on carbon black filled natural rubber (NR). The 3 constant standard triboelastic solid (STS) model and its behavior are described, in general terms and with s

Torsional dynamics can be extremely damaging to downhole drilling tools and can significantly affect drilling efficiency. Industry focus on combating this has led to the development of various downhole mitigation tools, improved bit technologies, BHA

Aspects of the mechanical behavior of filled vulcanizates are reviewed with reference to existing mathematical models. The basic equations of the triboelastic theory, previously described by Turner, are derived. A standard triboelastic solid (STS) th

A method is described for the physical simulation of the dynamic behaviour of the urinary bladder. It has been found that the model can be controlled to an arbitrary pressure–volume characteristic essentially independent of the properties of the bl

Tests have been performed on animal models shortly post-mortem and on a healthy human subject in order to obtain estimates of the forces which act on suprapubic urinary catheters and similar devices and to develop an abdominal wall simulator. Such da

Elastomeric components are widely used in engineering. Increasing demands are placed on them to withstand hostile conditions such as high temperature and corrosive environments. These demands make it harder to predict likely service life or improve d
