摘要： In a ventilator system and a method for controlling the ventilator system, a hand ventilator is connectable to a patient to impose a manually generated breathing pattern on the patient. A measurement unit is arranged by the hand ventilator to measure at least one of the parameters pressure and flow of the manually generated breathing pattern. The measured parameters are supplied to a memory unit in a regulatory unit, which operates a control unit so as to regulate a valve unit for imposing a mechanically generated breathing pattern, corresponding to the manually generated breathing pattern, on the patient. The measured parameters can be re-scaled in a calculation unit before the control unit controls the valve unit.

摘要： A flow regulator, suitable for use in a respirator/ventilator, has a conduit through which a medium flows whose flow is to be regulated and a choke valve arranged outside the conduit. The choke valve includes a first solenoid, a pressure actuator that is moved by the shaft end of the first solenoid, and a fixed element with the conduit disposed between the pressure actuator and the fixed element. Actuation of the first solenoid displaces the pressure actuator so as to alter the cross-section of the conduit. The shaft of the first solenoid exhibits an effective stroke length so that the pressure actuator, in a first limit position, leaves the flow cross-section of the conduit unaltered and, in a second limit position, partially compresses the conduit against the detent. The flow regulator is made lightweight and inexpensive and also has a comparatively low power consumption by using a second solenoid having a shaft which exhibits a short effective stroke length compared to the shaft of the first solenoid. In the end position shaft of the second solenoid exerts a pressure against the pressure actuator so as to compress the conduit further than the compression produced by the first solenoid and thereby to entirely suppress the flow.

摘要： A valve for regulating a gas flow has a valve housing with an inlet for the gas to be regulated, an outlet for a regulated gas flow, a valve seat with a valve opening, and a movable sealing part with a controllable shaft, the terminal side of the sealing part making and breaking a seal between the valve seat and the sealing part such that the sealing part closes and opens the valve opening and regulates the gas flow through the valve opening. In order to allow particularly small gas flows to be repeatedly regulated with high precision and a large dynamic, the plane of the terminal side of the sealing part and the plane of the valve seat form a non-zero angle, allowing the terminal side of the sealing part to press against the valve seat, or to detach therefrom, so that the terminal side gradually closes and opens the valve opening. Alternatively a preformed part is attached between the terminal side of the sealing part and the valve seat, this part being arranged obliquely relative to the valve seat and having a surface area which corresponds to at least the surface area of the valve seat. The terminal side of the sealing part is arranged such that it presses the obliquely arranged part against the valve seat, or detaches it therefrom such that the obliquely arranged part gradually closes or opens the valve opening.

摘要： A flow regulator, preferably in a respirator/ventilator, has a conduit through which a medium conduit flow is to be regulated flows and a choker valve arranged outside the conduit, the choker valve having pressure applicators arranged exactly opposite one another between which the conduit can be brought and act on the flow cross-section of the conduit such that they leave the flow cross-section of the conduit uninfluenced in a first limit position and press the conduit completely closed in a second limit position. In order to obtain a flow regulator of this type with a choker valve that is gentle on the conduit and which can also completely compress a conduit having a comparatively large flow cross-section, the pressure applicators are fashioned such that, when the conduit is compressed, both pressure actuators actively press it together from both, opposite sides.
