    • A CPR face mask has a substantially toroidal face engaging part positionable on the face of a patient to surround at least the mouth of the patient. A flexible generally conical part having a lower end extending around and is secured to an upper surface of the face engaging part, and an upper end with an aperture through which a CPR giving person can blow air which passes downwardly through the conical part and the toroidal part into the patient's mouth. The flexible generally conical part has a relatively short outwardly extending substantially horizontal portion at the lower end extending around and secured to the upper surface of the face engaging part, a relatively short portion extending upwardly and outwardly from an inner edge of the substantially horizontal portion, a relatively high frusto-conical portion extending upwardly and inwardly from an upper edge of the upwardly and outwardly inclined portion, a relatively short portion extending inwardly and downwardly from an upper edge of the frusto-conical portion and a central cylindrical portion extending upwardly from an inner edge of the inwardly and downwardly extending portion and providing said aperture. The mask can be positioned in a collapsed configuration for storage by downward movement of the central cylindrical portion to cause the frusto-conical portion to fold downwardly and extend into the toroidal face engaging part and can be returned to a ready-to-use configuration by an upward pull on the central cylindrical portion.

    • An oxygen therapy face mask has a face engaging portion and a valve assembly connected thereto. The valve assembly has a first passage communicating with the interior of the face engaging portion from which gas can flow into the face engaging portion and into a patient's mouth and nose and which can also receive gas from a patient's mouth and nose and the interior of the face engaging portion. A first one-way valve is associated with the first passage and a second passage connectable to an oxygen reservoir bag and to an external source of pressurized oxygen. The first one-way valve is operable to permit flow of gas from the second passage to the first passage and to prevent flow of gas from the first passage to the second passage. A second one-way valve is associated with the first passage and is operable to permit flow of gas from the first passage to the external atmosphere and to prevent flow of gas from the external atmosphere to the first passage. A third one-way valve is associated with the first passage and is operable to permit flow of gas from the external atmosphere to the first passage and to prevent flow of gas from the first passage to the external atmosphere. A patient can inhale oxygen which passes from the second passage through the first one-way valve and can also inhale air from the external atmosphere through the third one-way valve if sufficient oxygen is not available in the second passage.
    • 氧疗面罩具有与其连接的面接合部分和阀组件。 阀组件具有与面接合部分的内部连通的第一通道,气体可从该内部流入面接合部分并进入患者的嘴和鼻部,并且还可以从患者的嘴和鼻部接收气体, 面接合部。 第一单向阀与第一通道相关联,第二通道可连接到储氧袋和外部加压氧源。 第一单向阀可操作以允许气体从第二通道流到第一通道并且防止气体从第一通道流到第二通道。 第二单向阀与第一通道相关联并且可操作以允许气体从第一通道流到外部大气并且防止气体从外部大气流到第一通道。 第三单向阀与第一通道相关联并且可操作以允许气体从外部大气流到第一通道并且防止气体从第一通道流到外部大气。 患者可以吸入从第二通道通过第一单向阀的氧气,并且如果在第二通道中没有足够的氧气,也可以通过第三单向阀吸入来自外部大气的空气。

    • A CPR face mask has a face engaging part positionable on the face of a patient to surround at least the mouth of the patient. An air flow control valve is carried by the face engaging part and has an upper inlet into which air can be blown by a CPR giving person and which passes downwardly through a first outlet into a patient's mouth. The flow control valve causes air passing upwardly from the patient's mouth into the first outlet to be released to the external atmosphere through a second outlet without passing to the inlet. The flow control valve has a flexible diaphragm operable to prevent air flow from the inlet to the second outlet when the CPR giving person is blowing into the inlet and to prevent air flow from the first outlet to the inlet when air passes upwardly from the patient's mouth into the first outlet. A filter is located immediately upstream of the diaphragm with respect to air flow blown into the first inlet by the CPR giving person. The diaphragm having a filter-blocking position assumed during patient exhalation to protect the filter from patient-expired condensate.
    • CPR面罩具有可定位在患者面部上的至少围绕患者口部的面部接合部分。 空气流量控制阀由面部接合部分承载,并且具有上部入口,空气可以由CPR给予人吹送到空气中,并且向下通过第一出口进入患者口腔。 流量控制阀使得从患者口部向上流入第一出口的空气通过第二出口而释放到外部大气,而不通过入口。 流量控制阀具有可操作的柔性隔膜,当CPR给人进入入口时,当空气从患者口部向上流过时,可防止空气从入口到第二出口流动,并防止空气从第一出口流入入口 进入第一个出口。 相对于通过CPR给予人吹入第一入口的气流,过滤器紧邻隔膜的上游。 隔膜具有在患者呼气期间假设的过滤器阻塞位置,以保护过滤器免受患者失效的冷凝物的影响。
