  • Plaster cutting wire, plaster cast or dressing comprising such wire and method of manufacturing such a plaster cast or dressing
    Patent number: 4290424
    Abstract: The present invention relates to a plaster cast cutting wire (1) permitting the simple removal of a plaster cast or dressing. The plaster cast cutting wire comprises an anchoring plate (2) from which two substantially equally long cutting wire ends (3) extend. The cutting wire is positioned against the limb or body portion to be dressed and the plaster-of-Paris bandage is wound around both the body portion and the plaster cutting wire, in a way causing the plate (2) to become embedded in the cast. In order to facilitate removal of the plaster cast or dressing at least two plaster cutting wires will normally be used, thereby providing for division of the plaster cast into at least two parts upon removal. If the plaster cast or dressing is to be applied over a joint, the plates (2) are positioned opposite the joint on the outer and inner sides thereof.
