A device for removing viscous or semi-viscous material from an individual is disclosed. The device uses suction which may be provided by a vacuum source. The device includes a tube. The tube has a proximal opening and a distal opening, and a first stop at a first lengthwise position on an inner wall of the tube. The distal opening is in pneumatic communication with the vacuum source. The device also includes an agitator rotatably disposed in the tube. The agitator has a helical blade, a first end, and a second end. The first end is configured to engage the first stop such that the agitator is rotatable about the axis of the helical blade while being at a substantially fixed position along the length of the tube. |
