Abstract: A medical tube holder and its method of use are disclosed. The holder has a backing element having front and back faces, a portion of the back face having means to adhere to a substrate. The element has an elongate elastic strip having a free end and an end attached to the element suitable for wrapping around tubing to form a loop within which the tubing is held. Members possessing a mutual magnetic attraction are mounted on the front surface of the element for mutual engagement when the element is folded. After the tube is positioned within the loop, the free end of the strip is pulled to tighten the loop and is then positioned between the magnetic members. When the element is folded, the strip is held between the magnetic members to lock the tube within the loop.

Abstract: In an anisotropic polymeric magnet in tubular form, the magnetization orientation is directed in one direction perpendicular to the axial line of the tubular magnet. In a bipolar anisotropic magnet in tubular form, the magnetic poles can be formed only at symmetrical portions of the magnet with respect to the axial line and an imaginary line connecting the magnetic poles with each other is parallel to said one direction.In order to symmetrically distribute the magnetism around a tubular bipolar anisotropic magnet, a weld line(s) formed by injection molding of a mixture of ferromagnetic material powder and polymeric material is located in the portion(s) of the magnet where the magnetic poles are not formed.
