HEATER FOR SURGICAL VIEWING INSTRUMENTS

摘要

A system and associated method are used for warming an endoscope, laparoscope, or other such instrument to minimize fogging. A flexible pad has a length, a width and a periphery for wrapping around the instrument. An activation disc and a mixture of water and sodium acetate are used to generate heat through an exothermic reaction initiated through manual manipulation of the disc. The disc may be exposed in a flexible tab in fluid communication with the pad. A housing includes an end bore to receive the instrument such that the instrument is surrounded by the folded or rolled pad within the housing. The housing may further include a slit or narrow opening enabling the tab and activation disc to extend therethrough and outside the housing for activation.

1. A system for warming an endoscope, laparoscope, or other such instrument to minimize fogging, comprising:
a flexible pad having a seal periphery and filled with a sodium acetate solution; the flexible pad defining a plane in an unfolded state with a length and a width dimensioned to wrap around the instrument; an activation disc disposed in the sodium acetate solution causing the solution to generate heat through an exothermic reaction initiated through manual manipulation of the disc; and wherein the disc is disposed in a flexible peripheral tab in fluid communication with the sodium acetate solution.
