In order to drain the urinary bladder, a drainage system is proposed which has a drainage conduit with a urinary catheter end part for insertion into the bladder of a patient and a flow conduit in fluid communication with the catheter end part to permit urine to flow from the catheter end part to an outlet. The flow conduit has a tubular coupling section which is configured to collapse inwardly when the pressure within the dampening section falls below atmospheric pressure. The drainage conduit is thus configured to absorb kinetic energy and prevent or reduce pressure oscillation, reducing the risk of damage to the bladder, stuttering drainage and the possible reintroduction of expelled urine back into the bladder. |
