Abstract
A dual use urine collection assembly comprising a drainage tube assembly having a drainage tube connected to a proximal chamber and an atmospheric equilibrium valve disposed in fluid communication with the proximal chamber. The atmospheric equilibrium valve has an airway with a cross-sectional air inlet area, and the airway is connected to the proximal chamber at an interface having a membrane area. The membrane area is in the range of about 4 to about 8 times larger than the air inlet area. The proximal chamber has a hydrophobic breathable membrane disposed on an inside surface of the proximal chamber over the interface.
Claims20
A drainage tube assembly for an external incontinence device, the drainage tube assembly comprising:
- a drainage tube connected to a proximal chamber;
- and
- an atmospheric equilibrium valve disposed in fluid communication with the proximal chamber, the atmospheric equilibrium valve having an airway with a cross-sectional air inlet area, the airway connecting to the proximal chamber at an interface having a membrane area, the membrane area being in the range of about 4 to about 8 times larger than the air inlet area;
- and
- a hydrophobic breathable membrane disposed on an inside surface of the proximal chamber over the interface.
A drainage tube assembly for an external incontinence device, the drainage tube assembly comprising:
- a drainage tube connected to a proximal chamber;
- and
- two or more atmospheric equilibrium valves disposed in fluid communication with the proximal chamber, at least one of the two or more atmospheric equilibrium valves having an airway with a cross-sectional air inlet area, the airway connecting to the proximal chamber at an interface having a membrane area, the membrane area being in the range of about 4 to about 8 times larger than the air inlet area;
- and
- a hydrophobic breathable membrane disposed on an inside surface of the proximal chamber over the interface.
