目的:为了降低病房SARS病毒对医护人员的感染率,降低病人对SARS病毒的再吸入率。方法:采用紧闭面罩与双管双路、吸呼气道分离,高速射流空氧混合器、安全活瓣、储气囊、湿化器、负压吸引装置等相结合技术,将开放式吸氧变为紧闭式吸氧,使SARS病人呼出气病毒收集得以实现,为其过滤消毒创造了条件。过滤、消毒后排出室外。结果:降低SARS病毒对医护人员的感染率,降低病人对SARS病毒的再吸入率,促进康复,有重要意义。
Objective: In order to reduce the infection rate of ward SARS virus to medical personnel and reduce the re-inhalation rate of SARS virus in patients. Methods: Using a closed mask and dual-tube dual-channel, inhalation and exhalation airway separation, high-speed jet air oxygen mixer, safety valve, storage balloon, humidifier, vacuum suction device and other combined technologies will open oxygen Become closed oxygen, so that patients with SARS exhalation virus can be achieved to create conditions for filtration and disinfection. Filtered, disinfected and discharged outside. Results: It is of great significance to reduce the infection rate of SARS virus to medical personnel, reduce the re-inhalation rate of SARS virus in patients, and promote rehabilitation.
