1. A medical attachment device for maintaining positive fluid pressure in a patient, the attachment device comprising a body having a fluid outlet port, at least two positive pressure fluid inlet ports, and an obstructor holder comprising a fluid access port in fluid communication with the fluid outlet port;
wherein each of the at least two positive pressure fluid inlet ports is connectable to a respective first fluid source;
wherein each of the at least two positive pressure fluid inlet ports is in fluid communication with the fluid outlet port via the fluid access port;
wherein each of the at least two positive pressure fluid inlet ports comprises an attachment device mechanism for selectively starting and stopping a flow of fluid from the respective fluid source to the fluid outlet port;
wherein the attachment device mechanism is housed at least partially in the obstructor holder and comprises:
an arm having a first end in fluid communication with a respective one of the at least two positive pressure fluid inlet ports and a second end;
an obstructor in the first end configured to seal the fluid access port in the obstructor holder; and
a circular aperture in the second end to enable, by motion of the arm, selective fluid communication between the respective fluid inlet port and the fluid outlet port via the fluid access port.
