URINE COLLECTION BAG WITH INTEGRAL ANTI-REFLUX VALVE

PROBLEM TO BE SOLVED: To provide an anti-reflux valve to be more easily manufactured at low cost than that by conventional technique. SOLUTION: A urine collection bag 100 formed of at least one flexible material sheet defining a fluid reservoir is disclosed, which includes an anti-reflux valve 120. The anti-reflux valve 120 includes a valve housing defining a fluid receptacle which is placed outside the fluid reservoir. The valve housing has a peripheral rim with an anti-reflux valve secured adjacent to an inlet opening part formed in the at least one flexible material sheet to the at least one flexible material sheet. Here, the inlet opening part in the at least one flexible material sheet forms a flap in the at least one flexible material sheet; the flap is placed in the periphery of the peripheral rim of the housing to substantially seal the inlet opening part when fluid tends to flow from the fluid reservoir to the fluid receptacle.
