    • A fluid disinfection unit [40] is incorporated into a patient warming/cooling system [10], to reduce the risk of bacteria buildup in the warming/cooling fluid, which is typically water. More particularly, a mobile housing [17] contains the operable components for circulating warming/cooling fluid to a patient [12], including a pump [23], a heating/cooling source [24], a reservoir [22], a controller [26] and a control panel [32] to assist a user in operating the components. The reservoir [22] has upper [22a] and lower [22b] sections, for replenishing water and circulating water, respectively. A UV source [40] is mounted so as to extend through both reservoir sections [22a, 22b], to simultaneously emit UV light into both sections during circulation of the warming/cooling fluid, thereby to disinfect the water contained therein. The UV source [40] includes a bulb [42] protected within a transparent cover [44] that is completely transparent, and has been treated so as to be shatterproof. A sensor [70] mounted to the housing [17] detects the UV emission level within the reservoir [22], and generates a signal to indicate the on/off status of the UV bulb [42], and/or the magnitude of the UV light within the reservoir [22].
    • 将流体消毒装置[40]并入到患者加温/冷却系统[10]中,以减少通常为水的加温/冷却流体中细菌累积的风险。 更具体地,移动外壳[17]包含用于将加热/冷却流体循环到患者[12]的可操作组件,包括泵[23],加热/冷却源[24],储存器[22],控制器 [26]和控制面板[32],以帮助用户操作组件。 储层[22]具有分别用于补充水和循环水的上部[22a]和[22b]部分。 UV源[40]被安装成延伸穿过两个储存器部分[22a,22b],以在加热/冷却流体循环期间同时将UV光发射到两个部分中,从而对其中所含的水进行消毒。 UV源[40]包括保护在完全透明的透明盖[44]内并已被处理为防碎的灯泡[42]。 安装到壳体[17]的传感器[70]检测储存器[22]内的紫外线发射水平,并产生指示紫外灯泡[42]的开/关状态的信号,和/或 储层内的紫外光[22]。
