Abstract
In some examples, a method includes providing a leak detector having a body defining a viewing port, a sensor disposed within the viewing port, an inflow connection disposed on one side of the viewing port, and a vent disposed on an opposing side of the viewing port, wherein the inflow connection, the body and the vent define a lumen extending from the inflow connection through the viewing port and the vent, and coupling the leak detector to at least one of a chest tube and a chest tube drainage unit having a suction port.
Claims19
A method comprising:
- providing a leak detector having a body defining a viewing port, a sensor disposed within the viewing port, an inflow connection disposed on one side of the viewing port, and a vent disposed on an opposing side of the viewing port, wherein the inflow connection, the body and the vent define a lumen extending from the inflow connection through the viewing port and the vent;
- providing a symmetric double taper connector;
- choosing a position for the leak detector, the position being selected from a first position on a chest tube and a second position on a chest tube drainage unit having a suction port;
- coupling the inflow connection of the leak detector via the double taper connector to a first one of the first position on the chest tube and the second position on the suction port of the chest tube drainage unit;
- decoupling the inflow connection of the leak detector from the first one of the first position on the chest tube and the second position on the suction port of the chest tube drainage unit;
- and
- coupling the inflow connection of the leak detector via the double taper connector to a second one of the first position on the chest tube and the second position on the suction port of the chest tube drainage unit.
