ABSTRACT:
A retention device, particularly useful for drainage tubes and the like, having a pad for adhesive attachment to a patient's skin at the exit/entry site for a post-surgical drainage tube. The device includes a retainer body secured to the pad and provided with a strap to be looped and tightened about the drainage tube for immobilizing that tube. A passage in the body receives the free end of the strap and a latching mechanism prevents retraction of the strap unless a pair of side flanges of the body are squeezed towards each other to alter the configuration of the body's top wall and cause upward disengagement of a restraining pawl from the ratchet teeth of the strap. In one form of the invention, the strap is oriented horizontally and the passage is spaced well above the pad so that the horizontal plane of the passage substantially bisects the loop along its axis, thereby allowing portions of the loop to be located above and below the entrance to the passage. In another embodiment, the strap is oriented in a vertical plane and the pawl is cammed laterally and upwardly to disengage the strap when the side flanges are squeezed towards each other.
