1. A radiation shield for attenuating electromagnetic radiation, comprising:
- an electromagnetic-radiation-attenuating drape formed of lead-equivalent material;
an aperture through the drape and spaced from edges of the drape, allowing insertion of surgical equipment through the aperture to a patient;
a slit extending from the aperture to one of the edges of the drape;
a flap extending at least partially over the slit to hold the slit closed; and
a secondary shield formed of lead-equivalent electromagnetic-radiation-attenuating material, the secondary shield being releasably secured to the drape to cover the aperture.

Abstract
A radiation shield includes an aperture connected to an edge of the shield by a slit, which is held closed by a releasable flap. Instrumentation can be inserted through the aperture to contact a patient over which the shield is draped. By releasing the flap and thereby opening the aperture toward the edge of the shield, the shield can be removed from the patient without removing the instrumentation inserted through the aperture. A secondary shield is releasably secured over the aperture, affording further protection. Because the shield is placed within the septic field during use, the shield includes a sterilizable outer covering.

6. A shield for attenuating electromagnetic radiation, comprising:
-
a primary layer of electromagnetic-radiation-attenuating material having a periphery; an aperture through the layer and spaced from the periphery of the layer, allowing insertion of instrumentation through the aperture; an opening extending from the aperture toward the periphery, allowing the aperture to be opened toward the periphery and the shield to be moved without moving the instrumentation inserted through the aperture; a secondary layer of electromagnetic-radiation-attenuating material covering the aperture through the primary layer; and a slit extending at least partially across the secondary layer, dividing the secondary layer into at least two leaves. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A radiation shielding arrangement, comprising:
-
A) a shield for attenuating electromagnetic radiation, comprising; 1) a primary layer of electromagnetic-radiation-attenuating material having a periphery; 2) an aperture through the layer and spaced from the periphery of the layer, allowing insertion of instrumentation through the aperture; 3) an opening extending from the aperture toward the periphery, allowing the aperture to be opened toward the periphery and the shield to be moved without moving the instrumentation inserted through the aperture; a secondary layer of electromagnetic-radiation-attenuating material covering the aperture through the primary layer; a slit extending at least partially across the secondary layer, dividing the secondary layer into at least two leaves; and B) a support frame, comprising; 1) a support member from which the shield hangs; 2) a post that supports the support member; and 3) an attachment member that supports the post. - View Dependent Claims (21, 22)

23. A shield for attenuating electromagnetic radiation, comprising:
-
a primary layer of electromagnetic-radiation-attenuating material having a periphery; an aperture through the layer and spaced from the periphery of the layer, allowing insertion of instrumentation through the aperture; a primary opening in the primary layer extending from the aperture toward the periphery, allowing the aperture to be opened toward the periphery; a secondary layer of electromagnetic-radiation-attenuating material covering the aperture through the primary layer; a release mechanism for releasably securing the secondary layer to the primary layer; and a secondary opening extending through the secondary layer allowing insertion of the instrumentation through both the aperture and secondary opening, the secondary layer surrounding the instrumentation while the primary opening and the release mechanism allow the shield to be moved without moving the instrumentation inserted through the aperture and secondary opening. - View Dependent Claims (24)
