| 摘要 |
A multi-layer article to protect a patient from laser radiation during surgery comprises two metallic layers (12,16) sandwiching a flame-resistant, radiation absorbing layer (14). The facing surfaces of the metallic layers (12,16), adjoining the middle layer, are reflective. The top surface of the upper metallic layer has a non-reflective, flame-resistant coating (18). The radiation-absorbing layer (14) is preferably a hydrogel. The lower metallic layer (12) is preferably thicker than the upper layer and/or is of a metal that has a higher melting temperature than that of the upper layer. The article protects the patient by harmlessly dissipating the energy in a misdirected laser beam for a period of time that will permit a healthcare worker to take corrective action. <IMAGE> |
