Aspects of embodiments of the present invention disclose a suction adapter used in aspirating fluid from a particular site. The adapter device may include a nozzle configured to connect with suction tubing connected with a suction source, a drain end, structurally configured to connect the adapter with a drain tube, where the drain tube may be used to aspirate a site such as a surgical site. The adapter may also include: a channel within the adapter enabling fluid flow and a suction controlling fenestration extending from the channel to the adapter's external surface. The fenestration enables a user, by progressively opening or closing the fenestration, to vary suction within the suction adapter which, in turn, varies the flow of fluid through the adapter.
