Abstract
A suction canister including a patient port, a vacuum port, a chamber, and a protrusion including a thin portion which defines a passageway, the passageway extending into the chamber such that the protrusion can be broken to provide communication between the passageway and the chamber to enable draining of fluid from the suction canister.
Claims20
A suction canister comprising
- a container defining a chamber for collecting body fluids, said chamber being at least partially defined by a wall including a frangible wall portion such that said frangible wall portion can be broken to provide communication with said chamber, said frangible wall portion having a reduced thickness in a direction parallel to an axis, said container, including said frangible wall portion, being injection molded, and said wall being molded using mold parts movable relative to each other in a direction parallel to said axis,
- a patient port communicating with said chamber for communication with a patient cavity, and
- a vacuum port communicating with said chamber for communication with a vacuum source such that application of a vacuum to said vacuum port creates a vacuum in said chamber and thereby draws body fluids into said chamber via said patient port.
A suction canister comprising
- a container defining a chamber for collecting body fluids, said chamber being at least partially defined by a wall including a protrusion extending into said chamber and defining a passageway having an open outer end and a closed inner end and having an axis, said protrusion including a thin portion such that said protrusion can be broken to provide communication between said passageway and said chamber, said thin portion having a reduced thickness in a direction parallel to said axis, said container, including said thin portion, being injection molded, and said wall being molded using mold parts movable relative to each other in a direction parallel to said axis,
- a patient port communicating with said chamber for communication with a patient cavity, and
- a vacuum port communicating with said chamber for communication with a vacuum source such that application of a vacuum to said vacuum port creates a vacuum in said chamber and thereby draws body fluids into said chamber via said patient port.
A medical apparatus comprising
- a suction canister including a container defining a chamber for collecting body fluids, said chamber being at least partially defined by a wall including a frangible portion such that said frangible portion can be broken to provide communication with said chamber, said frangible portion having a reduced thickness in a direction parallel to an axis, said container, including said frangible portion, being infection molded, and said wall being molded using mold parts movable relative to each other in a direction parallel to said axis, a patient port communicating with said chamber for communication with a patient cavity, and a vacuum port communicating with said chamber for communication with a vacuum source such that application of a vacuum to said vacuum port creates a vacuum in said chamber and thereby draws body fluids into said chamber via said patient port, and
- a drainage device including a mechanism for breaking said frangible portion to provide communication with said chamber and thereby draining the contents of said chamber.
