Abstract:
A retention device for retaining a gas delivery system on a patient's head, comprising:a tube holder portion having a first end and a second end and a cylindrical tube having a length therebetween, said cylindrical tube defining a cylindrical cavity adapted to engage a supply tube; said tube holder portion further comprising a first tubular section and a second tubular section, the first tubular section adapted to engage the supply tube and maintain a tension upon the supply tube, and the second tubular section being adapted to engage a superior portion of an auricle proximate a helix portion of the auricle; said first tubular section including an inner tubular wall extending from said first end to said second end having an ovoid shape in cross section, said ovoid shape enabling said inner tubular wall to frictionally engage and maintain said tension on the supply tube passing therethrough; an ear stop portion having a first end and a second end and a length therebetween with the first end being connected to the tube holder and the second end being adapted to engage an inferior portion of an auricle proximate a lobule portion of the auricle; said tube holder portion and ear stop portion forming a substantially 7-shaped structure, wherein when in use said tube holder portion forms a horizontal leg of the 7-shaped structure and the ear stop portion forms an angled vertical leg of the 7-shaped structure; wherein when in use force on the tube generated by the tension between the tube holder portion's first tubular section and the tube is translated to the ear stop portion and wherein the supply tube's direction of travel is not redirected by the tube holder.
