Abstract

A waste disposal system for receiving pharmaceutical waste material including at least one of a solid phase pharmaceutical waste material and a liquid phase pharmaceutical waste material is provided. The waste receiver includes a receiver body defining an opening. The waster receiver further includes an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface. The outer surface defines a lock passageway separate from the opening. The system further includes a bracket adapted to be secured to a fixed surface and a locking assembly coupled to the bracket and adapted to releasably secure the waste receiver to the fixed surface. The locking assembly includes a lock housing sized to be removably positioned at least partially within the lock passageway.

First claim

What is claimed is:

1 . A waste disposal system for receiving pharmaceutical waste material including at least one of a solid phase pharmaceutical waste material and a liquid phase pharmaceutical waste material, the waste disposal system comprising:
a waste receiver comprising a receiver body defining an opening and comprising an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface, the outer surface defining a lock passageway separate from the opening; a bracket adapted to be secured to a fixed surface; a locking assembly coupled to the bracket and adapted to releasably secure the waste receiver to the fixed surface with the locking assembly comprising a lock housing sized to be removably positioned at least partially within the lock passageway; wherein the waste receiver further comprises a cover adapted to be coupled with the receiver body over the opening to seal the pharmaceutical waste material within the container volume for disposal of the waste receiver; and wherein the waste receiver further comprises a cover retention feature sized to removably receive the cover with the cover retention feature and the locking assembly cooperating to prevent removal of the cover when the locking assembly is securing the waste receiver to the fixed surface.

2 . The waste disposal system of claim 1 , wherein the locking assembly further comprises an engagement feature movable relative to the lock housing and adapted to engage a complementary engagement feature on the waste receiver when the lock housing is positioned within the lock passageway, wherein the locking assembly is adapted to be selectively actuated between an unlocked configuration in which the engagement feature is moved to disengage the complementary engagement feature to permit the waste receiver to be decoupled from the locking assembly, and a locked configuration in which the engagement feature is moved to engage the complementary engagement feature to prevent the waste receiver being decoupled from the locking assembly.

3 . The waste disposal system of claim 2 , wherein the cover retention feature is a lip coupled to a front of the receiver body with the locking assembly further comprising a lock cylinder extending from a front of the lock housing and spaced from the lip by a distance sufficient to retain the cover between the lip and the lock cylinder when the lock housing is positioned within the lock passageway and the receiver body is secured to the locking assembly.

4 . The waste disposal system of claim 3 , wherein the locking assembly further comprises a spindle operably coupled to the engagement feature of the locking assembly and adapted to be actuated to selectively actuate the locking assembly between the locked configuration in which the spindle disengages the engagement feature of the locking assembly, and the unlocked configuration in which the spindle engages the engagement feature of the locking assembly.

5 . The waste disposal system of claim 4 , wherein the locking assembly further comprises a decoupling member movable relative to the lock housing, and a biasing member disposed within the lock housing and biasing the decoupling member away from a vertical mount of the bracket, wherein a rear of the waste receiver is at a first distance from the vertical mount of the bracket when the locking assembly is in the locked configuration and, as the locking assembly is moved from the locked configuration to the unlocked configuration, the decoupling member moves the rear of the waste receiver to a second distance from the vertical mount of the bracket greater than the first distance.

6 . The waste disposal system of claim 5 , wherein the outer surface further defines the complementary engagement feature of the waste receiver comprising a channel extending between a front and rear of the receiver body and comprising a portion of the lock passageway with the complementary engagement feature of the waste receiver and the engagement feature of the locking assembly cooperating to orient the waste receiver relative to the locking assembly to a single orientation.

7 . The waste disposal system of claim 1 , wherein each of the lock passageway and the lock housing are oblong to facilitate orienting the waste receiver relative to the locking assembly as the waste receiver is removably coupled to the lock housing.

8 . A waste disposal system for receiving pharmaceutical waste material including at least one of a solid phase pharmaceutical waste material and a liquid phase pharmaceutical waste material, the waste disposal system comprising:
a waste receiver comprising a receiver body defining an opening and comprising an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface, the outer surface defining a lock passageway separate from the opening; a bracket adapted to be secured to a fixed surface; a locking assembly coupled to the bracket and adapted to releasably secure the waste receiver to the fixed surface with the locking assembly comprising a lock housing sized to be removably positioned at least partially within the lock passageway; and wherein the waste receiver further comprises a diverter coupled to the receiver body and disposed within the opening with the diverter comprising a body portion positioned within the opening of the receiver body, a solid receiver guide coupled to the body portion and adapted to direct the solid phase pharmaceutical waste material to a solid waste volume, and a liquid receiver guide coupled to the body portion and adapted to direct the liquid phase pharmaceutical waste material to a liquid waste volume separate from the solid waste volume.

9 . A method of securing a waste receiver for receiving pharmaceutical waste material including at least one of a solid phase pharmaceutical waste material and a liquid phase pharmaceutical waste material to a fixed surface, the waste receiver including a locking assembly comprising a lock housing and the waste receiver comprising a lock passageway, said method comprising the steps of:
securing the locking assembly to the fixed surface; mounting the waste receiver on the locking assembly such that the lock housing is positioned at least partially within the lock passageway; releasably securing the waste receiver to the locking assembly in a single orientation; wherein the waste receiver comprises a receiver body defining an opening and comprising an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface, the outer surface defining the lock passageway separate from the opening; and wherein the waste receiver further comprises a diverter coupled to the receiver body and disposed within the opening with the diverter comprising a body portion positioned within the opening of the receiver body, a solid receiver guide coupled to the body portion and adapted to direct the solid phase pharmaceutical waste material to a solid waste volume, and a liquid receiver guide coupled to the body portion and adapted to direct the liquid phase pharmaceutical waste material to a liquid waste volume separate from the solid waste volume.

10 . The method of claim 9 wherein the locking assembly further comprises an engagement feature movable relative to the lock housing and adapted to engage a complementary engagement feature on the waste receiver when the lock housing is positioned within the lock passageway, wherein the locking assembly is adapted to be selectively actuated between an unlocked configuration in which the engagement feature is moved to disengage the c
