    摘要: This invention comprises a respirator intended for connection to human or animal airways. A first device for supplying and receiving respiratory gas to and from the airways so that the lungs can be ventilated is combined with a second devices that provides a valve-regulated separate supply of gas to the airways independently of the respiratory gas flow provided by the first device. The second device incorporates at least one line used to supply gas under pressure. Furthermore there are a number of valves connected in parallel to this line, which provide a pulsating gas supply, and a control unit that can be used to control at least some of the gas pulse characteristics.

    摘要: In a respirator having an inspiration gas flow controlled by the expiration gas flow, in order to avoid triggering difficulties, particularly in the neonatal respiration therapy, the respirator is controlled such that a continuous gas flow flows through the inspiration and expiration lines. The gas flow is measured in the inspiration line by a gas flow sensor. The measured signal from the gas flow sensor is used to control a valve in the inspiration line, or a common line connected to the inspiration and expiration lines so that a constant gas flow is maintained in the expiration line.

    摘要: A method of mixing a plurality of gases in a specified proportion and dosing the resultant gas mixture comprises supplying individually controlled gas streams from suitable sources thereof in a pulse-like fashion to an enclosed chamber from where the resultant gas mixture can be delivered to a point of use, such as a patient undergoing anesthesiological or respirational treatment.Each gas source is connected, via feed lines each having a back-pressure valve and an on-off solenoid valve, via a common flow line to an enclosed mixing chamber. A first and, optionally, a second flow meter are operationally positioned between the common flow line and the enclosed mixing chamber and generate electrical signals in accordance with select properties of the gas streams passing through such flow meter. These signals are transmitted to a microprocessor-controlled regulating unit, which also controls the solenoid valves in accordance with a specified program to provide desired gas pulses to the enclosed mixing chamber. A display means, a memory means and an alarm means can be operationally connected with the regulating unit.
