  • Patent number: 11370006
    Abstract: A waste disposal system with a waste receiver for receiving pharmaceutical waste material. A locking assembly is secured to a fixed surface and actuated from a locked configuration to an unlocked configuration. A lock cylinder of the locking assembly may extend forward of a front wall of a receiver body of the waste receiver to engage a locking feature of the cover in the locked configuration. A cover retention feature may prevent axial decoupling of the cover from the receiver body. An engagement feature is moved to be disengaged from the receiver body, and the receiver body is moved away from the fixed surface to disengage the locking assembly from the cover. The cover is decoupled from the cover retention feature, and coupled with the receiver body to seal the pharmaceutical waste material. The locking assembly may be removed from a lock passageway for disposal of the waste receiver.

  • Publication number: 20140008259
    Abstract: A pharmaceutical waste disposal assembly (10) comprises a waste receiver (212) that receives pharmaceutical waste, the waste receiver (212) including a radio frequency identification tag (200) that is configured to transmit a radio frequency signal that identifies the waste receiver (212). The pharmaceutical waste disposal assembly (10) can further comprise a receiver retainer (1516) that selectively receives the waste receiver (212). The radio frequency identification tag (200) is configured to transmit the radio frequency signal that is usable to track a location of the waste receiver (212) regardless of whether or not the waste receiver (212) is positioned within the receiver retainer (1516). The receiver retainer (1516) can include an identification reader (1500) that reads the radio frequency signal and is configured to store information from the radio frequency signal that inhibits use of the waste receiver (212) following removal from and repositioning into the receiver retainer (1516).
