    • A circuit protection device for protection of sensitive components during high energy radiation sterilization that includes a support substrate and a protective housing. The substrate supports the sensitive components. The protective housing is hermetically coupled to the support substrate to seal the sensitive components within the protective housing. Preferably, the protective housing stops high energy used in the high energy sterilization from damaging the sensitive components from a predetermined exposure level of high energy sterilization. The circuit protection device may further include a protective conductor that is coupled to the support substrate on a side which is opposite the protective housing to prevent high energy from entering the opposite side of the support substrate. The circuit protection device can also include an energy absorbing material contained within an area sealed by the protective housing to absorb high energy byproducts produced by the protective housing stopping the high energy used in the high energy sterilization. Preferably, the support substrate is a circuit board, and the sensitive elements are semiconductors. Also, the high energy sterilization is E-beam sterilization and the high energy are electrons, and the high energy byproducts are x-rays.
    • 一种用于在包括支撑基板和保护壳体的高能量辐射灭菌期间保护敏感部件的电路保护装置。 基板支持敏感元件。 保护壳体气密地联接到支撑基板上以密封保护壳体内的敏感部件。 优选地,保护壳体阻止在高能量灭菌中使用的高能量,以从高能量灭菌的预定暴露水平损坏敏感部件。 电路保护装置还可以包括保护导体,该保护导体在与保护壳体相对的一侧耦合到支撑基板,以防止高能量进入支撑基板的相对侧。 电路保护装置还可以包括容纳在由保护壳体密封的区域内的能量吸收材料,以吸收由保护壳体产生的高能量副产品,从而阻止在高能量灭菌中使用的高能量。 优选地,支撑衬底是电路板,并且敏感元件是半导体。 此外,高能消毒是电子束灭菌,高能量是电子,高能量副产物是X射线。
