摘要： An interface unit for establishing an electrical coupling of a number of sensor wires from a combination of catheters with a number of electrical signal channels of a electrophysiological monitoring system has a number of electrical contacts for coupling individual wires with individual channels. Each contact is releasably engageable with an individual wire. A number of overlays which are removably locatable at the outer surface and are attached to the housing of the unit by binding rings. Each overlay carries on a face thereof a visible indication of a different one of a number of stored wire/contact configurations. The configurations are organized such that contacts for receiving wires from a same catheter are grouped together and the indication is formed as visibly differentiated regions, each de-marking a different grouping.

摘要： An inspiratory tube intended to serve as at least part of an inspiratory line in a ventilator, has a tube wall, a distal end, a proximal end, a gas flow channel for carrying a flow of breathing gas and an opening in the wall at a specific distance from one end of the inspiratory tube, this opening being adapted for connection to an expiratory device (40). The inspiratory tube has a constriction in the gas flow channel between distal end of the inspiratory tube and the opening, a first channel that proceeds within the tube wall, generally parallel to the gas flow channel, and which opens into the gas flow channel between the distal end of the inspiratory tube and the constriction, and a second channel that proceeds within the wall, generally parallel to the gas flow channel, which opens into the gas flow channel between the constriction and the opening. The channels can be connected to a pressure gauge for determining the rate of flow and pressure of gas flowing in the gas flow channel.

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.

摘要： A device for measuring a gas flow, has a measurement chamber and an ultrasonic transceiver unit which can be attached to the measurement (chamber over openings of the measurement chamber and which is provided with transmit and receive heads. The heads are directed against the openings of the measurement chamber, membranes being arranged between the measurement chamber and the transmit and receive heads which are permeable to ultrasound waves but largely impermeable to moisture and bacteria. In order to feed maximum acoustical energy to the ultrasonic transceiver unit while keeping moisture and bacteria away from the unit, the membranes are replaceably arranged close to the transmit and receive heads.

摘要： A fluid pressure release valve includes an aperture through which fluid can flow. An element is movable to unseal the aperture and to open the valve when a force exerted by the fluid in the valve exceeds a predetermined force. An electromagnetic biasing arrangement biases the element to seal the aperture and hold the valve closed against the escape of fluid with the predetermined force. The applied bias is variable according to changes in the sensed position of the element and a monitoring arrangement, cooperable with the solenoid, monitors the changes in its electrical properties as a shaft moves in the monitoring arrangement, indicating a change in position of the element. The monitoring arrangement also varies the bias to reduce the predetermined force responsive to the sensed change in position of the element indicating an opening of the valve.

摘要： A valve for regulating a gas or liquid has a valve housing with an inlet and an outlet. A valve seat is arranged in the valve housing and connects the inlet to the outlet via a valve opening. A valve body facing the valve seat is formed by a band attached at a first fixation point and a second fixation point. The first fixation point is at one end of a lever. An actuator is arranged on the other end of the lever to act on the lever so the distance between the first fixation point and the second fixation point increases. The band is then stretched, and the valve opening is exposed, enabling gas/liquid to flow toward the outlet. When the actuator's action on the lever is regulated, an exact flow of gas/liquid can be regulated.

摘要： In a method for detecting a variation, such as a variation in the concentration of a substance, in a flowing medium, a sample of the medium is made to flow past a sensor for detecting the variation, with the direction of flow of the sample being reversed and the velocity of the sample in relation to the sensor being reduced during passage of the sample through the sensor. A device for detecting such a variation contains a sensor and a pump controlled to reverse the direction of flow and to reduce the velocity of the sample of the medium for making a measurement of the sample.
