The use of various prostheses for voice rehabilitation after total laryngectomy has become widely accepted in recent years. Two different types of prostheses can be distinguished: non-indwelling devices, which can be removed and replaced by the patient, and indwelling voice prostheses, which have to be removed and replaced by a physician. In this report we describe the in vitro measurement of the airflow dynamics of the recently developed Provox low-resistance, indwelling voice prosthesis. Airflows used in these experiments varied from 0.05 to 0.4 ls-1. With increasing flows, the trans-device air pressure against airflow rates increased from 0.28 kPa to 1.36 kPa, while the mean airflow resistance decreased from 5.6 to 3.4 kPa l-1 s-1. From these data and by comparison with data for other prostheses, the Provox voice prosthesis shows favorable airflow characteristics.
近年来，全喉切除术后使用各种假体进行嗓音康复已被广泛接受。可以区分出两种不同类型的假体：非植入式装置，患者可以自行取出和更换；植入式语音假体，必须由医生取出和更换。在本报告中，我们描述了最近开发的Provox低阻力植入式语音假体气流动力学的体外测量。这些实验中使用的气流范围为0.05至0.4升/秒。随着气流增加，跨装置空气压力相对于气流速率从0.28千帕增加到1.36千帕，而平均气流阻力从5.6降至3.4千帕·升⁻¹·秒⁻¹。根据这些数据并与其他假体的数据进行比较，Provox语音假体显示出良好的气流特性。
