Bladder catheter set
View Patent ↗This invention proposes a urinary catheter set with a urinary catheter disposed in a sterile package, which urinary catheter has a catheter shaft, a catheter tip and a preferably funnel-shaped end on the collecting pouch end, with a cuff being disposed in the package, which cuff encloses the catheter shaft. The cuff is preferably disposed so as to be movable along the length of the catheter shaft.
1. A urinary catheter set comprising a urinary catheter disposed in a sterile package, said catheter having a catheter shaft, a catheter tip, and a collecting pouch end, said catheter set comprising a hollow cuff which encloses a section of the catheter shaft and is disposed inside the sterile package so as to be movable along the length of the catheter shaft, and
said cuff is a thin flat-compressed sheeting tube shaped to define a filling opening disposed towards the collecting pouch end and a discharge hole opposite the filling opening, the filling opening having a diameter at least double that of a diameter of the discharge hole.
2. The urinary catheter set according to claim 1 , in which the urinary catheter has a hydrophilic surface, and including a fluid reservoir disposed inside the package, said fluid reservoir containing a stored fluid capable of activating said hydrophilic surface, said fluid reservoir being separate and distinct from the cuff.
3. The urinary catheter set as claimed in claim 2 , in which the fluid reservoir is rupturable, while the package is closed, by exertion of pressure on the fluid reservoir, whereby said fluid completely wets the surface of the catheter after the fluid reservoir has been broken open.
4. The urinary catheter set as claimed in claim 2 , in which said fluid comprises at least one substance from the group consisting of water, saline solution, and a lubricating gel.
5. The urinary catheter set as claimed in claim 2 , in which said fluid comprises a 0.9 wt % saline solution.
6. The urinary catheter set as claimed in claim 2 , in which said filling opening is larger than the catheter shaft at one end of the cuff, and with the discharge opening closely fitting the catheter shaft at the opposite end of the cuff, whereby, upon activation of the hydrophilic surface of the urinary catheter, the fluid is at least partially collected through said filling opening into and within the cuff, and so that upon moving the cuff along the catheter shaft, most of the surface of the catheter shaft is uniformly wetted with the fluid.
