HYZ4(T)智能正压氧气呼吸器是我院历时七年研制出的新一代智能型高端呼吸器，以高可靠性闭路定量供氧、高灵敏性气囊欠压特征提取、高时效性阀门轴向自开启补气为核心，符合人机工学舒适佩戴原理，具有开机自检、状态监测、异常识别、智能报警、自组网集群无线通讯等独创智能模块，并配置可鼻眼隔绝防护、面部自适应贴合、高强镜片综合除雾功能的复合型全面量，已成为呼吸器国产替代的引领者，广泛应用于煤矿、消防、隧道、石化、船舶、实验室、地下建筑等领域。 The HYZ4(T) intelligent positive pressure oxygen respirator is a new generation of high-end intelligent breathing apparatus developed by our institute over a period of seven years. It features highly reliable closed-circuit quantitative oxygen supply, highly sensitive extraction of under-pressure characteristics of the airbag, and highly efficient axial self-opening and gas replenishment of the valve. It conforms to the ergonomic principle of comfortable wearing. It is equipped with unique intelligent modules such as self-check upon startup, status monitoring, anomaly recognition, intelligent alarm, and self-organizing network cluster wireless communication. It is also equipped with a composite full face mask with functions such as nose and eye isolation protection, facial self-adaptive fitting, and high-strength lens comprehensive defogging. It has become a leader in domestic replacement of breathing apparatus and is widely used in coal mines, fire protection, tunnels, petrochemicals, ships, laboratories, underground buildings and other fields.
