A pilot study was conducted to evaluate the efficacy of a membrane ventilating tube as a Eustachian tube prosthesis in 20 patients with otitis media. The design was based partly on assumptions since many of the physiological parameters required to calculate the gas transport processes have not been previously reported. An elementary gas transport model with assumed partial pressures of gases was developed. A semipermeable membrane covering a tympanostomy tube was fashioned and used to ventilate the middle ear cavity. From this preliminary investigation, the device successfully maintained atmospheric pressures in the tympanum, compensated for Eustachian tube malfunction, prevented otorrhea and recurrence of middle ear effusions.
开展了一项初步研究，以评估一种膜式通气管作为咽鼓管假体在20例中耳炎患者中的疗效。该设计部分基于假设，因为此前尚未报道计算气体传输过程所需的许多生理参数。建立了一个假设气体分压的基本气体传输模型。制作了一种覆盖鼓膜造孔管的半透膜，并用于使中耳腔通气。从这项初步研究来看，该装置成功维持了鼓室内的大气压，弥补了咽鼓管功能障碍，防止了耳漏和中耳积液复发。
