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.

Claims25

Dependent claims

A retention device for retaining elongate objects, comprising a retainer body having a passage extending therethrough and having an elongated strap with one end portion joined at a junction to said body and an opposite free end portion insertable into and through said passage to form said strap into an object-retaining loop;

said strap having a longitudinal series of transversely-extending ratchet teeth along one surface thereof;
said body including a pair of side walls having upper edges and extending along said passage;
a pair of side arms joined to said side walls along opposite sides of said body;
at least one of said arms being pivotally connected to one of said side walls along said upper edge thereof for pivotal movement towards and away from said one side wall;
said arms also including upper portions projecting above said upper edges of said side walls;
a flexible top wall joining said upper portions of said arms and having a central portion that is flexed into raised condition when said one arm is pivoted towards said one side wall;
and latching means extending downwardly from said central portion of said top wall for engaging said teeth and preventing reverse movement of said strap in said passage;
said latching means being lifted out of restraining engagement with said teeth when said arms are squeezed towards each other to cause pivotal movement of said one arm and upward flexure of said central portion of said top wall.

5 more elements

A drainage tube retention device comprising a flexible pad having upper and lower surfaces and having a pressure-sensitive adhesive layer along its lower surface for adherence of the pad to a patient's skin;

and tube retaining means mounted upon said upper surface comprising a retainer body having a passage extending therethrough;
an elongated strap having one end portion joined at a junction to said body and an opposite free end portion insertable into and through said passage to form said strap into a loop for receiving and holding a drainage tube;
said strap having a longitudinal series of transversely-extending ratchet teeth along one surface thereof;
said body having a pair of side walls extending along said passage;
said side walls being pivotally connected along upper edges thereof to a pair of lever arms;
said lever arms having relatively rigid lower portions extending downwardly below said edges and spaced laterally from said side walls and having upper portions projecting above said edges;
and a flexible top wall joining said upper portions of said lever arms;
said top wall having a central portion that normally curves downwardly into said passage when in an intensioned state but is raised and at least partially straightened when said lower portions of said lever arms are pivoted towards each other;
and latching means extending downwardly from said central portion of said top wall for engaging said teeth and preventing reverse movement of said strap in said passage;
said latching means being raised out of restraining engagement with said teeth when said lower portions of said lever arms are pivoted towards each other.
