    • PROBLEM TO BE SOLVED: To provide a system for increasing the temperature of a fluid being infused into a patient's body while infusion is taking place, and also to provide improved monitoring of air in the infusion system. SOLUTION: A disposable fluid infusion cartridge 100 comprises a heat exchanger 101 having upper and lower aspects and an internal heat exchange zone defined by a first and second plurality of overlapping fins and forming a substantially uniform flow path depth. Each fin has a ratio of height to width of at least 1:2, whereby fluid enters the lower aspect of the heat exchanger via a lower port and fills a lower flow cavity across the width of the heat exchange zone prior to flowing through the heat exchange zone and out an upper port at the upper aspect of the heat exchanger. The cartridge further has an air-trap 110 having upper and lower aspects and an inner surface for receiving the fluid from the heat exchanger, and further comprises an fluid flow disrupter and a purging mechanism for purging air from the air-trap and preventing air from passing beyond the air-trap.

    • 要解决的问题:提供一种用于在输注期间增加输入到患者体内的流体的温度的系统,并且还提供对输注系统中的空气的改进的监测。 解决方案:一次性液体输注盒100包括具有上部和下部方面的热交换器101和由第一和第二多个重叠翅片限定并形成基本上均匀的流动路径深度的内部热交换区域。 每个翅片具有至少1:2的高度与宽度的比率,由此流体通过下端口进入热交换器的下方,并且在流过热量之前在热交换区的宽度上填充下流动空腔 交换区,并在热交换器的上方形成上端口。 墨盒还具有具有上部和下部方面的空气阱110和用于从热交换器接收流体的内表面,并且还包括流体扰动器和用于从空气阱中吹扫空气的清洗机构, 超越了空气陷阱。 版权所有(C)2010,JPO&INPIT
