    • The present invention provides a breathing circuit for delivering a flow of gases to a patient, the circuit comprising a connector for connecting the circuit to a patient; an inspiration tube connected to the connector, the inspiration tube being connectable to a ventilator and for receiving an inflow of gases for the patient; and an expiration portion. The expiration portion comprises first and second expiratory tubes connected to the connector. The first expiratory tube is connectable to a ventilator, the first expiratory tube in use providing a first expiratory flow path from the patient via the connector and the first expiratory tube to the ventilator. The second expiratory tube is connected to an open-tail reservoir bag, the second expiratory tube in use providing a second expiratory flow path from the patient via the connector and the second expiratory tube to the reservoir bag. The system further comprises a valve operable to, in use, switch a flow of expiratory gases from the patient between the first and second expiratory flow paths. The system reduces storage space, material use and manufacturing costs whilst greatly enhancing convenience and safety for the patient.
    • 本发明提供了一种用于向患者输送气流的呼吸回路,所述回路包括用于将所述回路连接至患者的连接器; 连接到连接器的吸气管,吸气管可连接到呼吸机并用于接收患者的气体流入; 和到期部分。 呼气部分包括连接到连接器的第一和第二呼气管。 第一呼气管可连接到呼吸机,使用中的第一呼气管提供从患者经由连接器和第一呼气管到呼吸机的第一呼气流动路径。 第二呼气管连接至敞开式储存袋,第二呼气管在使用中提供从患者经由连接器和第二呼气管到达储存袋的第二呼气流动路径。 该系统还包括可操作以在使用中在第一呼气流动路径与第二呼气流动路径之间切换来自患者的呼气气流的阀。 该系统减少了存储空间,材料使用和制造成本,同时大大增强了患者的便利性和安全性。

    • Apparatus and method is disclosed for vaporizing a liquid anesthesia agent in a carrier gas for delivery to a patient such that the apparatus automatically establishes, monitors, and maintains a predetermined concentration level of the anesthesia agent in the carrier gas. The apparatus has an inlet and an outlet with a vaporization chamber therebetween, and a pump for dispensing small quantities of liquid anesthesia agent into the vaporization chamber. A first sensor senses the condition of the carrier gas upstream from the vaporization chamber and a second sensor senses the condition of the carrier gas/vaporized agent downstream from the vaporization chamber. A computer control system responsive to the sensors is configured to determine the concentration level of the agent delivered to the patient and to automatically increase or decrease the rate at which the pump is actuated to maintain the concentration level at the predetermined level.
