An insertable anti-occlude strip includes a strip made of a material that is flexible, sturdy, durable and compression resistant. The strip has a cross-sectional shape such that when the strip is inserted into a hollow, flexible tube, there are open longitudinal apertures formed between the strip and the inner wall of the tube, allowing bi-directional flow of air or fluids through the tube. The insertable and tubal anti-occlude strip, when inserted into a hollow and flexible tube, provides resistance to occlusion of the tube lumen when the tube is under compressive or shear forces, which would otherwise significantly reduce or halt flow of air or fluids through the tube.
