Abstract
An oral suction device includes a suction catheter having a suction portion at a first end, a sponge surrounding the suction portion, a hydrogel or non-hydrogel polymer coating on the sponge, and a suction tubing connector on a second end opposite the first end. In some aspects the coating is a hydrogel coating that does not have macropores. A method of making an oral suction device may include dip-coating a sponge and forming macropores in the coating during the coating process.
