Injection molded adjustable shape abscess irrigation device
An adjustable shape abscess irrigation device includes a first tube that is slidably associated with a second tube. The irrigation device includes a retainer that defines a variable shape diameter. The diameter of the retainer is selectively adjustable by the relative positioning of the first tube and the second tube such that, once placed relative to an abscess, the shape of the device can be manipulated to allow desired drainage of irrigation and abscess fluids beyond the confines of the abscess. Upon adequate drainage of the abscess, the cross-section shape of the retainer can be reduced to facilitate more comfortable and less detrimental removal of the device from the patient. Preferably, the irrigation device is formed via one or multi-shot injection molding and is formed of more than material.
1. An abscess irrigation device comprising:
a tube having an elongate shape that extends between a first end and a second end;
a fluid path formed through the tube along the elongate shape that is unobstructed between the first end and the second end of the tube;
a sleeve movably supported by the tube and having a first sleeve end and a second sleeve end, a gap defined between an interior surface of the sleeve and an exterior surface of the tube along an entire longitudinal length of the sleeve;
a retainer secured to the sleeve and the tube, the retainer having at least two arms that extend in an outward radial direction relative to a longitudinal axis of the tube, a degree of extension of the arms from the longitudinal axis being adjustably defined by a position of the sleeve relative to the tube; and
a vent formed through the retainer that fluidly connects the fluid path to a physiologic cavity and the gap defined between the sleeve and the tube.
2. The device of claim 1 wherein the vent is further defined as at least two openings.
3. The device of claim 2 wherein the at least two openings are oriented in different directions.
4. The device of claim 1 wherein a distance between adjacent arms maintains a gap between anatomies adjacent the anus.
5. The device of claim 1 wherein the sleeve is at least one of radially or longitudinally movable relative to the tube to alter a distance that the arms extend from the longitudinal axis.
6. The device of claim 1 wherein the tube is constructed of a less pliable material than the retainer.
7. The device of claim 1 wherein the retainer further comprises as least one living hinge associated with each of the at least two arms.
8. The device of claim 1 wherein the gap defines another fluid path formed between the tube and the sleeve that uninterruptably fluidly connects the physiologic cavity and atmosphere.
9. The device of claim 1 wherein the tube is longer than the sleeve.
10. The device of claim 1 wherein the at least two arms overlap a portion of the tube and are offset in a longitudinal direction from each of the first sleeve end and the second sleeve end throughout a range of motion between the sleeve and the tube.
