Suction canister and corresponding systems and methods
View Patent ↗A canister lid ( 101 ) for a canister ( 102 ) includes an annular perimeter ( 103 ) surrounding an interior portion ( 104 ). Rather than completely surrounding the interior portion, the annular perimeter is instead interrupted by a suction conduit ( 112 ) defined by a suction conduit ( 112 ) separating a first lobe ( 117 ) and a second lobe ( 118 ). The suction conduit ( 112 ) intersects the annular perimeter such that the first lobe is disposed interior of the annular perimeter while the second lobe is disposed exterior to the annular perimeter. The canister lid can further include one or more ports ( 110,111 ) extending from the interior portion. A canister ( 102 ) can include a valve ( 401 ) and can optionally be coupled to a hub mount vacuum source ( 1200 ) or a hub mount stand ( 1800 ).
1. A canister system, comprising:
a canister lid comprising an annular perimeter interrupted by a suction conduit defined by a suction duct separating a first lobe and a second lobe, the first lobe disposed interior of the annular perimeter, the second lobe disposed exterior to the annular perimeter, and the suction duct traversing the annular perimeter; and
a canister comprising a valve coupled to a mechanical support extending distally from a canister sidewall, the valve defining a duct from the second lobe of the canister lid when the canister lid is coupled to the canister;
wherein the canister lid defines a top side and an canister engaging side, the first lobe is disposed above a first aperture, the second lobe is disposed above a second aperture, and each of the first lobe and the second lobe are disposed on the canister engaging side of the canister lid.
2. The canister system of claim 1 , the valve disposed between the second lobe and the mechanical support.
3. The canister system of claim 2 , the valve further comprising a shaft terminating at a push button, the shaft selectively translatable laterally between a first position and a second position to turn the valve ON or OFF, respectively.
4. The canister system of claim 3 , the shaft comprising visual indicia to indicate whether the valve is ON or OFF.
5. The canister system of claim 4 , the visual indicia comprising a recess defined in the shaft.
6. The canister system of claim 2 , the valve comprising a plank selectively translatable laterally between a first position and a second position to turn the valve ON or OFF, respectively.
7. The canister system of claim 6 , the plank defining a concave recess at an end of the plank.
8. The canister system of claim 6 , the plank comprising visual indicia to indicate whether the valve is ON or OFF.
9. The canister system of claim 8 , the visual indicia comprising one or more of color coding or text.
10. The canister system of claim 2 , the valve comprising a twisting control mechanism to selectively rotate about the valve between a first position and a second position to turn the valve ON or OFF.
11. The canister system of claim 10 , the twisting control mechanism comprising a paddle responsive to a force to axially rotate the twisting control mechanism about the valve.
12. The canister system of claim 2 , wherein the valve is selectively detachable from the mechanical support.
13. The canister system of claim 1 , wherein the mechanical support is disposed between the valve and the second lobe, wherein the valve is selectively detachable from the mechanical support.
14. The canister system of claim 13 , wherein the valve comprises:
a plank disposed between two O-ring seals, the plank defining an aperture to selectively align with a conduit defined axially in the valve to turn the valve ON; and
a rubber valve insert that allows the valve to be removably inserted into a valve receiver of the canister disposed beneath the mechanical support.
15. The canister system of claim 1 , the valve coupled directly to the second lobe without a tube or hose.
16. The canister system of claim 1 , the suction conduit defining a double-ended lollipop shape in plan view.
17. A canister system, comprising:
a canister lid comprising an annular perimeter interrupted by a suction conduit defined by a suction duct separating a first lobe and a second lobe, the first lobe disposed interior of the annular perimeter, the second lobe disposed exterior to the annular perimeter, and the suction duct traversing the annular perimeter; and
a canister comprising a valve coupled to a mechanical support extending distally from a canister sidewall, the valve defining a duct from the second lobe of the canister lid when the canister lid is coupled to the canister;
wherein the mechanical support is disposed between the valve and the second lobe, wherein the valve is selectively detachable from the mechanical support;
wherein the valve comprises:
a plank disposed between two O-ring seals, the plank defining an aperture to selectively align with a conduit defined axially in the valve to turn the valve ON; and
a rubber valve insert that allows the valve to be removably inserted into a valve receiver of the canister disposed beneath the mechanical support.
18. The canister system of claim 17 , the valve coupled directly to the second lobe without a tube or hose.
19. The canister system of claim 17 , the suction conduit defining a double-ended lollipop shape in plan view.
20. The canister system of claim 17 , the plank comprising visual indicia to indicate whether the valve is ON or OFF.
