A new device has been developed to provide complete de-airing of the heart after cardiopulmonary bypass. The apparatus consists of a special aspiration needle threaded to the bottom of a transparent bulb. A 1-way flutter valve is mounted at the top of the bulb, which creates a vacuum when the bulb is squeezed. This device has been used in 4 adults and 2 children, for both congenital and acquired heart disease. Preliminary results have shown that this device's active suctioning of air results in effective removal of air from the cardiac chambers; the transparent bulb enables the surgeon to visually determine that the de-airing procedure is complete.
一种新设备已被研发出来，用于在体外循环后实现心脏的完全排气。该装置由一根特殊的抽吸针组成，该针穿过一个透明球囊底部。一个单向扑动阀安装在球囊顶部，当挤压球囊时会产生真空。该装置已应用于4名成人和2名儿童，治疗先天性和后天性心脏病。初步结果表明，该装置对空气的主动抽吸能有效清除心腔内的空气；透明球囊使外科医生能够直观地确定排气过程已完成。
