Height adjustable medical bucket
A height-adjustable bucket or height-adjustable stand is adapted to carry a medical object. The bucket includes a receptacle for carrying the medical object, a base, and a support member coupled to the base. The bucket also includes a carrier movably coupled to the support member and for supporting the receptacle and a lifting member slidably coupled to the carrier and configured to move between a raised position and a lowered position. The lifting member includes a first end portion comprising a handle and a second end portion, and a retainer selectively coupling the carrier to the support member and configured to selectively retain the carrier in the relatively high position. The lifting member is configured to be in the lowered position when the carrier is in the relatively high position and when the carrier is in the relatively low position.

4. The height-adjustable bucket of claim 3 , wherein said dampening assembly comprises a pulley, a tension member, and a dampener, said tension member extending between said dampener and said carrier to assist in moving said carrier between said relatively high position and said relatively low position, said pulley facilitating a change in direction of said tension member between said dampener and said carrier.
5. The height-adjustable bucket of claim 4 , wherein said dampening assembly is a single direction system such that said dampening assembly is configured to provide controlled movement of said carrier only from said relatively high position to said relatively low position.
6. The height-adjustable bucket of claim 4 , wherein said dampener is a rotary dampener.
7. The height-adjustable bucket of claim 4 , wherein said dampener is coupled to an underside of said base.
8. The height-adjustable bucket of claim 1 , wherein said lifting member defines an exterior engagement surface and an engagement member, wherein said exterior engagement surface is configured to be activated by a user and said engagement member is configured to be moved from a first position to a second position upon activation of said exterior engagement surface to cause said carrier to be decoupled from said support member.
9. The height-adjustable bucket of claim 8 , wherein said support member comprises an interior engagement surface configured to be actuated by said engagement member and a piston configured to selectively uncouple said retainer assembly and said carrier to allow said carrier to move to said relatively low position upon actuation of said interior engagement surface by said engagement member.
10. The height-adjustable bucket of claim 1 , wherein said carrier and said retainer assembly are mechanically coupled to each other when said carrier is in said relatively high position.
11. A height-adjustable bucket adapted to carry a medical object, said bucket comprising:
a receptacle for carrying the medical object;
a base;
a support member coupled to said base;
a carrier movably coupled to said support member and said carrier for supporting said receptacle, wherein said carrier is configured to move between a relatively high position and a relatively low position along an axis defined by said support member, wherein said carrier comprises a coupling member; and
a retainer on said support member selectively coupling said carrier to said support member and configured to selectively retain said carrier in said relatively high position,
wherein when said carrier is in said relatively high position and said retainer is coupling said carrier to said support member, and wherein said coupling member of said carrier and said retainer are configured to automatically decouple from one another when contents of said receptacle has a mass greater than a predetermined mass that exceeds a retention force of said coupling member and said retainer.
12. The height-adjustable bucket of claim 11 , wherein said retainer includes a first coupling member and said carrier includes a second coupling member and wherein at least one of said first coupling member and said second coupling member engage one another to retain said carrier in said relatively high position and define a force therebetween.
13. The height-adjustable bucket of claim 12 , wherein one of said first and second coupling members comprise a rod including a shoulder configured to be engaged with the other of said first and second coupling member.
14. The height-adjustable bucket of claim 13 , wherein said second coupling member comprises a ball-nose plunger configured to be engaged with said shoulder of said rod to retain said carrier in said relatively high position.
15. The height-adjustable bucket of claim 14 , wherein said rod includes a ramped surface spaced apart from said shoulder along said axis, and wherein said ramped surface is configured to allow said ball-nose plunger to slide along said ramped surface during movement of said carrier from said relatively low position to said relatively high position.
16. The height-adjustable bucket of claim 15 , wherein said ball-nose plunger is spring-loaded to assist sliding motion of said ball-nose plunger along said ramped surface of said rod.
17. The height-adjustable bucket of claim 11 , further comprising a lifting member slidably coupled to said carrier, said lifting member including a first end portion comprising a handle and a second end portion, opposite said first end portion.
18. The height-adjustable bucket of claim 11 , further comprising a dampening assembly configured to provide controlled movement of said carrier when said retainer is decoupled from said carrier.
19. The height-adjustable bucket of claim 18 , wherein said dampening assembly comprises a pulley, a tension member, and a dampener, said tension member extending between said dampener and said carrier to dampen movement of said carrier from said relatively high position to said relativity low position, said pulley facilitating a change in direction of said tension member between said dampener and said carrier, wherein said dampener is configured to provide a dampening force that is within 20% of said force between said retainer and said carrier.
20. A height-adjustable stand adapted to carry a medical object, said stand comprising:
a base having an upper most surface;
a support member coupled to said base;
a carrier movably coupled to said support member and for supporting a medical device, wherein said carrier is configured to move between a relatively high position and a relatively low position along an axis defined by said support member;
a retainer selectively coupling said carrier to said support member and configured to selectively retain said carrier in said relatively high position;
