A plastic catheter mount.
Among the disadvantages of catheter mounts in common use is that, as generally manufactured, they have sharp interior angles militating against laminar flow. The diagram illustrates the longitudinal section of a plastic variant in which the narrowing has been chamfered off. It has been found satisfactory in practice, and seems to be standing up robustly to use. It has the additional advantage o...
متن کاملConquering Mount Fuji: Resolution of Tension Pneumocephalus with a Foley Urinary Catheter
Tension pneumocephalus is the presence of air or gas in the cranium that is under pressure. It occurs due to disruption of the skull, including trauma to the head or face, after neurosurgical procedures and occasionally, spontaneously (Schirmer et al., 2010). Patients typically present with headache but can also have neurological deficits such as decreased mental status, numbness, and weakness ...
متن کاملA prospective randomized trial of the LoFric hydrophilic coated catheter versus conventional plastic catheter for clean intermittent catheterization.
PURPOSE We compared the incidence of hematuria, pyuria and clinical urinary tract infection in patients who performed intermittent self-catheterization using a hydrophilic coated LoFric (Astra Tech AB, Mölndal, Sweden) or standard plastic catheter. MATERIALS AND METHODS A total of 62 male patients who performed intermittent self-catheterization to manage neurogenic bladder were randomized int...
متن کاملGrazing Bifurcations and Chaos of a Hydraulic Engine Mount
The constitutive relationships of the rubber materials that act as the main spring of a hydraulic engine mount are nonlinear. In addition to material induced nonlinearity, further nonlinearities may be introduced by mount geometry, turbulent fluid behavior, temperature, boundary conditions, decoupler action, and hysteretic behavior. In this research all influence the behavior of the system only...
متن کاملVehicle Interior Vibration Simulation-a Tool for Engine Mount Optimization
By new advancements in vehicle manufacturing vehicle quality evaluation and assurance has become a more critical issue. In present work, the vibration transfer path analysis and vibration path ranking of a car interior has been performed. The method is similar to classical multilevel TPA methods but has distinct differences. The method is named VIVS which stands for Vehicle Interior Vibratio...
