A surgical bowl set features a first rectilinear bowl having an internal length (1l) and an internal width (1w), and a second rectilinear bowl having an external length (2l) and an external width (2w), in which the external length (2l) is close to but less than internal length (1l) in order to permit the second bowl to fit lengthwise within the first bowl while allowing easy extraction of the second bowl from the first bowl, and the external width (2w) is about half or less of internal width (1w).

A waste disposal system (30) with a waste receiver (32) for receiving pharmaceutical waste material. A locking assembly (34) 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 (44) of a receiver body (36) of the waste receiver to engage a locking feature of a cover (82) in the locked configuration. A cover retention feature (124) may prevent axial decoupling of the cover from the receiver body. The receiver body may be formed from two shells (62,64). A reaction agent (150) is positioned within the container volume and spaced apart from a bottom wall of the receiver body. The reaction agent may be positioned within the container volume between the lock passageway (94) and/or a solid receiver volume, and opposing sidewalls of the receiver body. A support may maintain the position of the reaction agent within the container volume.

A method of pre-treating a contaminated medical instrument that is to undergo decontamination involves inserting a distal tip of the instrument into a distal tip protector. The distal tip of the instrument is inserted through a rupturable resilient seal into an internal cavity of the protector that contains a fluid. The distal tip protector thereby maintains a fluid around the distal tip of the instrument until the distal tip protector is removed to allow reprocessing of the instrument to take place, facilitating decontamination of the instrument.

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.

A waste receiver for receiving pharmaceutical waste material and adapted to be releasably secured to a fixed surface is disclosed. The waste receiver comprises a receiver body with a fluid absorber and a chemical composition disposed within the receiver body. The receiver body defines an opening for receiving the pharmaceutical waste material and comprises an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface with the outer surface defining a lock passageway through the receiver body and a keyway comprising a portion of the lock passageway. The lock passageway is adapted to receive a locking assembly and the keyway is adapted to receive an engagement feature of the locking assembly to releasably secure the waste receiver to the locking assembly in a single orientation. The waste receiver also comprises a cover adapted to be coupled with the receiver body.
