肺功能仪即肺功能测试仪，是用于测量由肺部吸入和呼出的空气体积的一种医疗器械，可以分析受测者 呼出气体的一系列参数，如氧气含量、二氧化碳含量、肺活量（SVC）、用力肺活量（FVC）、每分钟 通气量（MV）等，用以整体了解受测者肺功能的基本状态，对受试者肺功能、有氧运动能力、能量消 耗等进行评价，判断肺功能是否存在障碍，以及评估障碍的程度及类型。 肺功能仪的使用优点 内容概要：受空气污染、人口老龄化加剧、不良生活方式等诸多因素影响，近年来，我国呼吸系统疾病 患病率持续攀升，尤其是老年人，老年人呼吸道黏膜萎缩、肺功能衰退，对病原体和环境刺激的抵抗力 减弱，患病率更高，但此前肺功能检查的临床普及率长期偏低，随着居民健康意识提升，无论是医疗机 构的临床诊断需求，还是患者居家监测、健康人群体检的筛查需求，都在持续释放，据比地招标网数据 显示，2024年我国肺功能仪采购总额为4.22亿元，与2023年基本持平，但由于采购均价上涨，2024年我 国肺功能仪采购总量下滑明显，降至1602台。 相关上市企业：美好医疗（301363）、康泰医学（300869） 相关企业：浙江柯洛德健康科技有限公司、广州红象医疗科技有限公司、武汉珈 ...

Core Insights - The portable spirometer market in China is projected to reach 444 million yuan in 2024, reflecting a year-on-year increase of 9% driven by policy support and rising demand [1][7]. Industry Overview - Portable spirometers are essential medical devices for lung function testing, first introduced by Breath Home in 2014, and have received certifications from NMPA, FDA, and CE [3]. - These devices are compact, easy to carry, and suitable for various settings, including community health service centers and home monitoring, facilitating early detection of chronic respiratory diseases [3][4]. Market Dynamics - The aging population in China is increasing, with the elderly population expected to reach 219.69 million by the end of 2024, contributing to a higher prevalence of chronic respiratory diseases and a growing demand for lung function tests [4]. - The number of medical institutions in China is projected to reach 1,093,600 by 2024, a year-on-year increase of 2.13%, indicating a growing market for portable spirometers [5]. Competitive Landscape - The market has historically been dominated by international brands like Jaeger and R spirometry, but domestic companies such as Mindray, Yuyue Medical, and Kangtai Medical are gaining market share through innovation and expansion [9]. - Mindray reported a revenue of 25.834 billion yuan in the first three quarters of 2025, a decrease of 12.38% year-on-year, while Kangtai Medical achieved a revenue of 344 million yuan in the first half of 2025, an increase of 3.03% year-on-year [10][11]. Development Trends - The industry is expected to see continuous technological innovation and product upgrades, with the integration of IoT, big data, and AI enhancing the precision and intelligence of portable spirometers [11]. - Competition is intensifying as both domestic and international brands increase R&D investments and market efforts, leading to potential mergers and acquisitions within the industry [12]. - The pace of domestic substitution is accelerating, with local manufacturers poised to replace imported products as they enhance their technological capabilities and market presence [13].
