Abstract

A method provides flow to multiple channels in an endoscope during an endoscope decontamination procedure. A member is inserted into a chamber in a body of an endoscope through an opening into the chamber, the chamber being intersected by a first lumen and a second lumen. The member separates fluidly the first lumen from the second lumen. Fluid is flowed through a first channel through the member into the first lumen and through a second channel through the member into the second lumen. Additional lumens can be so treated at the same time. Fluids can include detergents and other cleaning fluids, disinfectants and sterilants.

Claims

1. A method of providing flow to multiple channels in an endoscope during an endoscope decontamination procedure, the method comprising the steps of:

inserting a first member into a first chamber in a body of an endoscope through an opening into the first chamber, the first chamber being intersected by a first lumen and a second lumen;

separating fluidly the first lumen from the second lumen in the first chamber via the first member;

flowing fluid through a first channel through the first member into the first lumen;

flowing fluid through a second channel through the first member into the second lumen,

and moving the first member within the first chamber by flowing fluid under pressure through a third channel in the first member into the first chamber to move the first member outwardly thereof whereby to reduce occlusion.

2. A method according to claim 1 wherein a third lumen intersects the first chamber, and further comprising the steps of separating fluidly the third lumen from the first lumen and the second lumen via the first member and flowing fluid through a fourth channel through the first member into the third lumen.

3. A method according to claim 1 and further comprising the step of inserting a second member into a second chamber in the body of the endoscope through an opening into the second chamber, the second chamber being intersected by a third lumen and a fourth lumen;

separating fluidly the third lumen from the fourth lumen in the second chamber via the second member;

flowing fluid through a fourth channel through the second member into the third lumen; and

flowing fluid through a fifth channel through the second member into the fourth lumen.

4. A method according to claim 3 wherein the first member and second member are connected to each other.

5. A method according to claim 1 wherein the fluid is a cleaning fluid.

6. A method according to claim 1 wherein the fluid is a disinfectant or a sterilant.

7. A method according to claim 1 wherein the fluid is liquid.

8. A method according to claim 1 wherein the step of moving the first member within the first chamber further comprises urging the first member into the first chamber via a biasing member.
