A device is provided for removing fluid from a body cavity. The device is a catheter that can be securely anchored to a patient to improve comfort and prevent infections and contamination. To accomplish this, the catheter is provided with (1) an inflatable disk and (2) a securing ring. When the catheter reaches a proper location in the body cavity, the inflatable disk is inflated and comes into contact with an inner surface of the body cavity. To further secure the catheter into place, the securing ring is then moved into position against the epidermis. In this configuration, the tissue between the epidermis and the body cavity is engaged by both the inflatable disk and the securing ring. This ensures that the catheter remains in place and can continue to operate effectively while promoting patient comfort.
