Embodiments disclosed herein are directed to drainage bag systems configured to facilitate disposal of a fluid therein and methods of using the drainage bag systems. For example, the drainage bag systems may include a drainage container configured to receive and hold a fluid from a patient. The drainage container may be fluidly coupled and reversibly attached to a bag. The bag may be configured to selectively receive at least some of fluid held by the drainage container. The bag may be detached from the drainage container and disposed of in a substantially fluid tight manner without disrupting operation of the drainage container (e.g., receiving and holding a fluid).
