Closed chest drainage is typically necessary following Lobar and Sublobar resections to evacuate gases and fluids from the thoracic cavity, eliminate residual pleural space for lung expansion, and maintain negative pressure. Currently, three conventional closed chest drainage systems are commonly employed: single-chamber, double-chamber, and triple-chamber systems; each system has its own advantages and disadvantages. Despite the emergence of digital drainage systems in recent years, their high cost hinders their widespread adoption. Based on this premise, our research team has achieved a patent for a micro air pump-integrated chest closed drainage bottle, which has been further developed into a novel device integrating a three-chamber system with negative pressure control and power supply capabilities. This device enables patients undergoing perioperative lung procedures to ambulate freely while simultaneously receiving chest suction therapy-a concept that theoretically promotes rapid postoperative recovery. Moreover, this device offers economic benefits and holds potential for clinical implementation (particularly in economically underdeveloped regions). In this article, we modified the thoracic closed drainage device based on our patent and presented this novel thoracic closed drainage device after 3D printing and assembly.
胸腔闭式引流通常是在肺叶切除和亚肺叶切除术后进行的，以排出胸腔内的气体和液体，消除肺扩张后的残余胸膜腔，并维持负压。目前，常用的闭式胸腔引流系统有三种：单腔、双腔和三腔系统；每种系统都有其优缺点。尽管近年来出现了数字化引流系统，但由于其成本高昂，限制了其广泛应用。基于这一前提，我们的研究团队已经为一种带有微气泵的胸腔闭式引流瓶申请了专利，并进一步开发出一种具有负压控制和电源功能的新型三腔系统集成设备。该设备使接受围手术期肺部手术的患者能够在自由活动的同时接受胸部抽吸治疗，这一理念从理论上促进了术后的快速康复。此外，该设备还具有经济效益，并具有临床应用的潜力（特别是在经济欠发达地区）。在本文中，我们基于专利对胸腔闭式引流装置进行了改进，并在 3D 打印和组装后展示了这种新型的胸腔闭式引流装置。
