Abstract
A method of removing body fluids from a patient and disposing of the body fluids, the method comprising the steps of (a) providing a container including a bottom wall having therein a drain, (b) providing a drainage device for automatically opening the drain and draining the contents of the container, (c) collecting body fluids in the container, (d) placing the container on the drainage device, and (e) operating the drainage device so that the drainage device opens the drain and drains the contents of the container.
Claims18
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 having increased frangibility relative to the remainder of said wall such that said frangible wall portion can be broken to provide communication with said chamber, said container, including said wall and said frangible wall portion, being injection molded,
- 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 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,
- wherein said wall includes a first wall portion defining a passageway having an open outer end, and a second wall portion defining a blind inner end of said passageway, and wherein said frangible wall portion connects said first and second wall portions such that said second wall portion can be disconnected from said first wall portion to provide communication between said passageway and said chamber by breaking said frangible portion,
- wherein said second wall portion defines an outwardly opening, non-circular socket, and wherein said frangible portion is broken by inserting a tool into said socket and rotating said tool.
