中耳吹张法在中耳炎治疗中一直被认为是有用的。本文基于改良的Valsalva氏技术介绍一种新的便于儿童使用的自我吹张装置。其中鼻压记录仪由麻醉口罩和一浮球型流量计组成。另外在外耳道内插入一耳塞,同时接连一声谱分析仪以测试咽鼓管开放时进入耳道的声音。 Middle-ear blowing is always considered to be useful in the treatment of otitis media. This article presents a new self-blowing device for children, based on the modified Valsalva technique. The nasal pressure recorder consists of an anesthesia mask and a float-type flowmeter. In addition, insert an earplug in the external auditory meatus, followed by a spectrum analyzer to test the sound of the ear canal when the eustachian tube is open.
