近两年,美国与加拿大的医学专家发现,吸气阻力锻炼器(IRT)可使许多类型的肺疾患者,尤其是老年阻塞性肺疾病人,改善呼吸机能,子防呼吸疲劳,提高生活能力和运动能力。 IRT的商品名为“PFLEX”,长约12cm,中空,由硬质塑料制成。它的一端似烟嘴,可以含在口中,另一端有一个单向呼吸活瓣,使得IRT产生的阻力仅出现于吸气时。IRT
In the past two years, medical experts in the United States and Canada have found that the inhalation resistance exercise device (IRT) can improve the respiratory function, prevent respiratory fatigue and improve the living ability of many types of lung disease patients, especially elderly patients with obstructive pulmonary disease And athletic ability. The IRT trade name is “PFLEX”, about 12 cm long, hollow and made of a rigid plastic. It has a cigarette-mouth at one end that can be contained in the mouth and a unidirectional respiration valve on the other end, so that resistance to IRT occurs only at inhalation. IRT
