Abstract
Various embodiments of a fluid collection system having multiple storage chambers are disclosed. In an exemplary embodiment, the system may include a first chamber in fluid communication with a suction source and a second chamber in fluid communication with the first chamber.

A liquid collection chamber comprising:
- a main body configured to collect liquid;
- an inlet port for connecting to an external tube and through which liquid is received;
- an outlet port through which the liquid is discharged, an interior of the main body being in fluid communication with an exterior of the main body via the outlet port;
- and
- an overflow mechanism separate and distinct from the outlet port, the overflow mechanism being located radially adjacent to the outlet port relative to a longitudinal axis extending through the outlet port, and the overflow mechanism extending into the outlet port,
- wherein the outlet port is configured to selectively be opened and closed, the outlet port draining liquid collected in the interior of the main body to the exterior of the main body when open,
- wherein the overflow mechanism is configured to drain liquid from the interior of the main body to the exterior of the main body at least when the outlet port is closed.
