Shielding device and method
Some embodiments of a shielding device can include a base and a shield coupled to the base. The shielding device can be used to provide protection for a healthcare worker (e.g., physician, nurse, technician) during a medical procedure.
1. A radiation shielding device, comprising:
a radiation shield; and
a base comprising:
a substructure attachable to an object; and
a retainer structure attachable to the radiation shield,
wherein the retainer structure comprises an adjustable coupling operable between an unlocked condition in which an angular position of the shield is adjustable to a user-selected position, and a locked condition in which the angular position of the shield is substantially fixed;
wherein the retainer structure comprises a lock knob threadingly engaged with the adjustable coupling to operate the coupling between the locked and unlocked conditions;
wherein the lock knob is engageable with the shield; and
wherein the lock knob comprises a head including a plurality of flanges extending radially outward from a cylindrical body, and wherein the shield comprises one or more grippers to reach between the flanges and grip the cylindrical body.
2. The shielding device of claim 1 , wherein the retainer structure comprises a clamp member bearing against the lock knob when the coupling is in the locked condition to fix the angular position of the shield by frictional forces.
3. The shielding device of claim 2 , wherein the adjustable coupling permits movement of the shield with at least two degrees of freedom.
4. The shielding device of claim 3 , wherein the permitted movement of the shield includes circumduction movement.
5. The shielding device of claim 4 , wherein the shield is contoured widthwise in a convex orientation relative to a front side of the shield.
6. The shielding device of claim 5 , wherein the shield defines an outwardly projecting lip at the top of the shield and a broad arcuate midsection.
7. The shielding device of claim 6 , wherein a bottom portion of the shield comprises at least one notch to receive a tubular work piece installed on a patient.
8. The shielding device of claim 7 , wherein a radius of curvature of the lip of the shield is about 5 mm to about 10 mm, and the radius of curvature of the midsection is 3 cm to 10 cm.
9. The shielding device of claim 8 , wherein an overall size of the shield is sufficient to cover an area where a healthcare worker would position his/her hands during a medical procedure.
10. The shielding device of claim 9 , wherein the radiation shield comprises a barium sulfate, and the radiation shield has a nominal density of 1.5 g/cm3 to 2.5 g/cm3.
