Universal transfer adapters and methods of using the same

An apparatus, comprising:

• a housing having a proximal end portion and a distal end portion and defining an inner volume, the proximal end portion having a proximal coupler;
• a fluid communicator disposed in the inner volume of the housing and fluidically coupled to the proximal coupler;
• a stage disposed in the housing and movable between a first position and a second position;
• and
• a bias member disposed in the housing and in contact with a proximal side of the stage, the bias member configured to bias the stage in the first position such that the stage substantially prevents access to the fluid communicator via the distal end portion of the housing, the bias member allowing the stage to be moved to the second position in response to a force exerted on a distal side of the stage such that a portion of the fluid communicator extends through the stage, thereby allowing access to the fluid communicator via the distal end portion of the housing.

A method of using a transfer adapter, comprising:

• coupling a fluid collection device to a proximal coupler of the transfer adapter, the transfer adapter having a housing with a proximal end portion and a distal end portion, the proximal coupler disposed along the proximal end portion, the transfer adapter including a fluid communicator disposed in an inner volume of the housing and fluidically coupled to the proximal coupler;
• transitioning a lock coupled to the distal end portion of the housing from a locked configuration to an unlocked configuration;
• moving a stage disposed in the inner volume of the housing from a first position in which the stage limits access to the fluid communicator via the distal end portion of the housing to a second position in which at least a portion of the fluid communicator extends through the stage;
• and
• allowing a flow of bodily fluid into or out of the fluid collection device coupled to the proximal coupler via the fluid communicator when the stage is in the second position.
