摘要

3D打印在生物医学科学领域的应用越来越广泛,这表明了它在广泛的研究和医疗保健应用中的实用性,包括它在呼吸分析学科中的潜在实施,以克服当前商业呼吸采样接口的局限性和大量成本。本技术说明报告了3d打印口器适配器的设计和结构,用于使用商业呼吸收集器进行体外分析(receva)设备对呼出气体进行采样。本文介绍了适配器的设计和数字工作流程转换,以及使用Formlabs Form 3B立体光版(SLA)打印机从三种商业树脂(Surgical Guide, Tough v5和BioMed Clear)制造适配器。与传统的商用硅口罩采样接口相比,对与肺功能过滤器结合使用的口器适配器进行了评估。除了其较低的成本(尽管打印设备的投资成本)之外,3d打印适配器还有几个好处,包括确保通过口腔进行呼吸采样,减少患者与呼吸采样管直接接触的可能性,并且可高压灭菌,以便重复使用单个适配器,从而减少浪费和相关的环境负担,与目前的单向一次性口罩相比。本技术说明中介绍的用于呼吸采样的新型适配器代表了3D打印的另一个应用领域,进一步证明了其在生物医学中的广泛适用性。

3D-printed mouthpiece adapter for sampling exhaled breath in medical applications.

The growing use of 3D printing in the biomedical sciences demonstrates its utility for a wide range of research and healthcare applications, including its potential implementation in the discipline of breath analysis to overcome current limitations and substantial costs of commercial breath sampling interfaces. This technical note reports on the design and construction of a 3D-printed mouthpiece adapter for sampling exhaled breath using the commercial respiration collector for in-vitro analysis (ReCIVA) device. The paper presents the design and digital workflow transition of the adapter and its fabrication from three commercial resins (Surgical Guide, Tough v5, and BioMed Clear) using a Formlabs Form 3B stereolithography (SLA) printer. The use of the mouthpiece adapter in conjunction with a pulmonary function filter is appraised in comparison to the conventional commercial silicon facemask sampling interface. Besides its lower cost - investment cost of the printing equipment notwithstanding - the 3D-printed adapter has several benefits, including ensuring breath sampling via the mouth, reducing the likelihood of direct contact of the patient with the breath sampling tubes, and being autoclaveable to enable the repeated use of a single adapter, thereby reducing waste and associated environmental burden compared to current one-way disposable facemasks. The novel adapter for breath sampling presented in this technical note represents an additional field of application for 3D printing that further demonstrates its widespread applicability in biomedicine.
