Self-contained systems and methods for controlled dispensing of hazardous fluid

A system for controlled dispensing of biological fluid from a sample collection container, the system comprising:

• a fluid control module having an inlet, an outlet, and one or more conduits for routing fluid between the inlet and the outlet;
• a housing at least partially containing a receiving element and a suction element,
• wherein—
• the receiving element is in fluid communication with the fluid control module at the inlet and is configured to receive the sample collection container, and
• the suction element is in fluid communication with the fluid control module between the inlet and the outlet;
• and
• an actuator operably coupled to the suction element and configured to movably transition the suction element between a first state and a second state, wherein the actuator includes a lid having a plurality of tracks coupled to a portion for the suction element, the plurality of tracks being positioned to guide the suction element from the first state toward the second state when the lid is rotated relative to the housing,
• and wherein—
• moving the suction element from the first state toward the second state induces a negative pressure within at least a portion of the fluid control module to withdraw the biological fluid from the sample collection container and into the suction element, and
• moving the suction element from the second state toward the first state induces a positive pressure within at least a portion of the fluid control module to expel the biological fluid from the suction element and toward the outlet.
