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. A method of forming an anatomical drainage tool comprising:
positioning a first tube concentrically with respect to a second tube;
connecting the first tube to the second tube with a head portion and a deformable portion wherein the deformable portion includes a living hinge and the first tube and the second tube are connected such that a passage is formed between the first tube and second tube and a relative positioning of the first tube to the second tube manipulates a radial diameter of the drainage tool via movement of the living hinge of the deformable portion; and
forming a plurality of vents in the head portion that are fluidly connected to a passage associated with the first tube and orienting the plurality of vents in the head portion such that at least one of the vents is directed in a longitudinal direction aligned with a longitudinal axis of the first tube and another of the plurality of vents is directed in a radial direction relative to the longitudinal axis of the first tube.
2. The method of claim 1 wherein manipulating the radial diameter of the drainage tool is performed by at least one of longitudinally translating and rotationally translating the second tube relative to the first tube.
3. The method of claim 1 further comprising forming the living hinge with a plurality of members that each extend in different radial directions from a longitudinal axis of the first tube.
4. The method of claim 1 further comprising forming the plurality of vents in the head portion such that a plurality of openings are directed in different radial directions relative to the longitudinal axis of the first tube.
5. The method of claim 1 further comprising forming the living hinge with a material that is more pliable than at least one of the first tube and the second tube.
6. The method of claim 1 further comprising injection molding the first tube, the second tube and the living hinge.
7. A method of forming an anatomical drainage tool comprising:
positioning a first tube concentrically with respect to a second tube such that an interior of the first tube defines a first portion of an irrigation passage and a space between the first tube and the second tube defines a second portion of the irrigation passage and one end of the second portion of the irrigation passage is exposed to atmosphere when the anatomical drainage tool is associated with an abscess;
connecting an end of the first tube to an end of the second tube with a head portion and a deformable portion such that positioning of the first tube relative to the second tube manipulates a radial diameter associated with the deformable portion via movement of the living hinge; and
forming a plurality of vents in the head portion that are fluidly connected to the first portion of the irrigation passage associated with the first tube and orienting the plurality of vents in the head portion such that at least one of the plurality of vents is directed in a longitudinal direction aligned with a longitudinal axis of the first tube and at least two of the plurality of vents are directed in different radial directions relative to the longitudinal axis of the first tube such that the plurality of vents and any gaps between adjacent flexible arms associated with the deformable portion fluidly connect the first portion of the irrigation passage to the second portion of the irrigation passage.
