摘要： In the illustrated embodiment, the moisture reservoir comprises a tube of gas-permeable, hygroscopic material. The exhalation flow path is into a blind axial bore of a spool like member having a series of transverse notches or cuts at the top and bottom which provide interspaces leading from the bore to the tube which covers the notches at their periphery. The notches leave integral fins or lamellae with large surface area exposed to the in-flow of dry respiration gas radially through the tube wall and into the interspaces which provide further reservoirs for moisture and warmth.

摘要： A method and apparatus for independent monitoring of a flow-through quantity and, potentially, of a concentration of a gas flow that is extremely small in comparison to a respiratory gas flow is provided. The valve for the control of this small gas flow can not be controlled via the overall gas flow. In order to be able to simply and reliably monitor the flow-through quantity and the concentration of this small gas flow without a gas analyzer and independently of gas flow regulators that are usually present, it is provided that the small gas flow be separately measured and compared to a value derived from the respiratory gas flow. Given the presence of prescribable criteria, an alarm is triggered and the flow-through quantity of the small gas flow is, for example, interrupted.

摘要： A ventilator to be connected to the airways of a human or an animal includes several functional units, each functional unit being controlled and/or supervised by a separate microprocessor. At least one of the functional units has an analog control unit whereby the microprocessor only compensates for the coarseness in the regulating function of the analog control unit to increase the accuracy. This makes the ventilator efficient, accurate and safe.

摘要： A ventilator for supplying and emitting respiratory gas to and from the airways of a human or an animal patient has a multiple-function safety valve located between a 10 control valve and the airways. The safety valve is biased in its closing direction by two springs, which apply force that corresponds to a predetermined overpressure, and is biased in its opening direction by a spring loaded piston, which applies force that exceeds the force of the springs. When electrical power is supplied to the ventilator, an electromagnet is energized. The electromagnet pulls the piston against the force of its spring load, and the safety valve closes. By means of a control device, the pressure in an inspiration section of the ventilator can be monitored and the electromagnet is disconnected at a programmed overpressure. In the event of a power failure, the safety valve will open and air can pass through the open safety valve to the airways.

摘要： An apparatus, such as a ventilator, for regulating the flow-through amount of a flowing medium, such as a gas, has a valve with a variable orifice operated by a first regulating circuit with negative feedback. The regulating variable generated by the first regulating circuit controls the size of the orifice so that the difference between a desired value and an actual value for the flow-through amount os minimized, toward zero. To achieve rapid changes in the flow-through amount with a high regulating precision, at least one further regulating circuit is provided to which the regulating variable of the first regulating circuit is supplied as the desired value. The actual value for the further regulating circuit may be the measured position of the closure element for the orifice. The bandwidth and the gain can be optimized for each regulating circuit. The energy consumption can be lowered by current recovery and battery operation can be simplified, in the event of a power outage.

摘要： Equipment for administering gaseous anesthetic to a patient has at least one anesthetic reservoir serving as the originating source for anesthetic and a ventilator to which the gas is supplied from the reservoir, the ventilator being in communication with the breathing passages of a patient. To maintain the consumption of anesthetic gas as low as possible and to also assure that the patient is constantly ventilated with fresh anesthetic gas having a defined consumption, the exhalation gas from the patient is fed back to the originating anesthetic source via at least one filter in which predetermined gas components, such as water vapor and carbon dioxide are filtered out. The exhalation gas may be returned to the originating source either directly or through a compressor.

摘要： In a method an apparatus for vaporizing anesthetic liquids, in which a carrier gas is passed through a vaporizer so as to be saturated with vaporized anesthetic liquid, the vaporizer has a container, partially filled with anesthetic liquid, an inlet for a carrier gas, an outlet for carrier gas saturated with anesthetic and a pressure chamber. The carrier gas is supplied to the vaporizer at a pressure exceeding atmospheric pressure and is bubbled through the anesthetic liquid in the container in order to become saturated with anesthetic. The flow of gas at the outlet can be regulated as needed. Exact pressure and temperature conditions can be measured and/or regulated with a pressure meter, pressure regulator, thermometer and temperature regulator in order to regulate the partial pressure of anesthetic in the container.

摘要： In conjunction with the diagnosis of conditions in and treatment of the lungs, a small amount of NO is supplied to the lungs in some cases. A gas mixture for this purpose is disclosed in which an inert, non-toxic trace gas is present in an exact concentration in relation to NO, in order to simply and safely control the amount of NO then supplied to the lungs. The amount of NO supplied can be determined by determining the concentration of the trace gas. A method and device for administering breathing gas to a patient together with the aforementioned gas mixture are also disclosed.

摘要： In a method for supplying fresh gas in manual ventilation of a patient and in a ventilator system for practicing the method, the supply of fresh gas to a breathing bag is regulated. During inspiration, the breathing bag is squeezed, imposing an inspiration on the patient. A detector at the breathing bag senses when the patient exhales, and an identical flow of gas is fed to the system via an inspiratory valve, the flow of fresh gas is directed into the breathing bag and expired gas is prevented from entering the breathing bag. An expiratory valve simultaneously opens to conduct expired gas out of the system.

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.
