      catheters.

AB  - The urinary catheter is a thin plastic tube that has been designed to empty the 
      bladder artificially, effortlessly, and with minimum discomfort. The current CH14 
      male catheter design was examined with a view to optimizing the mass flow rate. 
      The literature imposed constraints to the analysis of the urinary catheter to 
      ensure that a compromise between optimal flow, patient comfort, and everyday 
      practicality from manufacture to use was achieved in the new design. As a result 
      a total of six design characteristics were examined. The input variables in 
      question were the length and width of eyelets 1 and 2 (four variables), the 
      distance between the eyelets, and the angle of rotation between the eyelets. Due 
      to the high number of possible input combinations a structured approach to the 
      analysis of data was necessary. A combination of computational fluid dynamics 
      (CFD) and design of experiments (DOE) has been used to evaluate the "optimal 
      configuration." The use of CFD couple with DOE is a novel concept, which 
      harnesses the computational power of CFD in the most efficient manner for 
      prediction of the mass flow rate in the catheter.
