Abstract

A suction canister is formed by a container on which is secured a lid provided with a plurality of ports, one of which is corrected to a suction source and another of which is connected by a hose used to suction fluids at a patient bedside. The port connected to the patient hose is acutely inclined at the top of the lid at an angle of 15° -30° whereas the other ports are upright. The lid is provided with tabs at its interior serving as cams to tightly fit the lid on the mouth of the container by pressing the lid on the container without twisting the lid. A shield on the inside of the lid prevents splashing suctioned liquid from prematurely contacting a hydrophobic shut off filler installed in the suction ports.

Claims

1. A suction canister comprising a container having an open top and a lid secured on the container at the open top, said lid being secured on the container to provide a tight fit engagement therebetween, said lid having a plurality of ports adapted for connection with various hoses, a first said port being a patient port connectable to a hose for providing suction for patient use, and a second said port being a suction port connectable to a hose connected to a suction system providing suction, and a plurality caps attached to the lid for sealing connection to respective ones of said ports, said patient port extending from the cap at an acute angle relative to the lid, said suction port containing a hydrophobic shut-off filter which closes the suction port when contacted by liquid suctioned into the container and reaching the level of the shut-off filter.

2. The suction canister of claim 1, wherein said patient port projects at an angle of about 15 to 30°

from said lid.

3. The suction canister of claim 2, wherein said angle is 20°

.

4. The suction canister of claim 1, comprising a curved shield on an underside of the lid facing an opening of said patient port to block contact of suctioned fluid with the hydrophobic shut-off filter.

5. The suction canister of claim 1, wherein said lid has an outer rim and a circular inner wall facing said rim and spaced therefrom to receive the open top of the container therebetween, and a plurality of tabs distributed around said lid, said tabs having inclined cam surfaces extending from said rim towards said inner wall at an angle to press the mouth of the container against said wall to provide said tight-fit of the lid on the container.

6. The suction canister of claim 5, wherein said cam surfaces are inclined towards said inner wall in a direction of insertion of the container into the lid whereby the lid is tightly fitted on the container by insertion of the mouth of the container into the lid without relative twisting of the lid and the container.

7. The suction canister of claim 1, wherein said lid has a third said port of larger diameter than the other ports for emptying liquid which has been suctioned into the canister.

8. The suction canister of claim 1, wherein said container and lid are made of inexpensive material so that the canister is adapted for one-time use.

9. The suction canister of claim 8, wherein the material of the lid and container is plastic.

10. The suction canister of claim 9, wherein the plastic material is styrene.

11. The suction canister of claim 1, wherein the lid has a further said patient port.
