设计本新型鼓泡器的原则:1.采用微孔发泡法搅动作用提高氧合力;2.充分利用降低表面张力和机械性去泡作用,提高消泡能力;3.采用多层次不同孔径的海绵和滤布滤尽微粒。在结构上分为两部份:1.可反复使用的充氧变温部份为一有机玻璃园柱筒,内藏一可脱卸的螺纹不锈钢管,经过冷热水进行降升血温,筒的下方嵌镶一狭长槽,内装340个细孔的充氧发泡钛管。2.一次使用的塑料袋,分隔成三部,上部供收集心内回血用,其右下方部份为去泡室,由包裹浸涂硅油的海绵和绵纶织布的粗大塑料管组成;其左下方部份作贮藏氧合血用,靠近进出口处装一尼龙过滤网。本氧合器将热交换氧合、去泡、过滤、收集回心血,贮血和测温等功能组合成一体,简化了体外循环的装置和运转,为目前唯一具有如此多功能的氧合器。经130例体外循环心内直视手术的临床使用,效果满意。
The principle of the design of the new bubbler: 1. The use of microporous foam agitation to improve oxygenation; 2. Make full use of reducing surface tension and mechanical deaeration to improve defoaming capacity; 3. The use of multi-level and different pore size Sponge and filter cloth filter out particles. Structurally divided into two parts: 1. Reusable oxygenation temperature part of a plexiglass cylinder, built-in a detachable threaded stainless steel tube, cold water to lower blood temperature, the tube Embedded below a narrow slot, built-in pores of oxygen-rich foam tube. 2. A used plastic bag, divided into three, the upper for the collection of blood back to the heart, the lower right part of the defoaming chamber, wrapped in silicone oil impregnated sponge and nylon woven coarse plastic pipe composition; its Part of the lower left for storage of oxygenated blood, near the mouth of a nylon filter installed. The oxygenator heat exchange oxygenation, defoaming, filtering, collecting blood back to the heart, blood storage and temperature measurement and other functions into one, simplifying the device and operation of extracorporeal circulation, is currently the only such a multifunctional oxygenator . After 130 cases of cardiopulmonary bypass open heart surgery clinical use, the effect is satisfactory.
