A system and process are provided for monitoring the valves of an anesthetic dispenser with a safety valve (2) and with a dispensing valve (3) for dispensing the anesthetic in the form of a vapor. The valves are connected in series. A system has a downstream dispensing gap (5) and a fixed bypass resistance (9). The system and process include the steps: a) the dispensing valve (3) is first opened for an equalization time, b) the safety valve (2) and the dispensing valve (3) are closed and the differential pressure between the saturated vapor branch (4) and the mixed gas branch (8) is measured by means of a differential pressure sensor (6, 7), c) the safety valve (2) or the dispensing valve (3) is opened and the differential pressure between the saturated vapor branch (4) and the mixed gas branch (8) is measured by means of the differential pressure sensor (6, 7), d) the opened safety valve (2) or the opened dispensing valve (3) is closed and the difference between the differential pressures measured in steps b) and c) is determined and compared with a preset limit value, so that e) the valve (2, 3) that is not opened in step c) is considered to be tight when the difference is below this limit value.
摘要:
An alarm is associated with a device for dispensing volatile anesthetics. The alarm and device is designed such that an alarm is triggered whenever the operating voltage is interrupted and an assembly unit that determines the dispensing of at least one anesthetic is not in a prescribed state of operation.

A pressure-resistant tank for liquids includes a plurality of differently shaped diecast parts (1, 2) made of a first aluminum alloy (cast alloy). The diecast parts (1, 2) are connected by means of a closed weld seam welded with an electron beam with the use of a second aluminum alloy (wrought alloy). The second aluminum alloy has especially a hydrogen content of less than 0.2 mL per 100 g of wrought alloy. The tank for liquids is especially an anesthetic tank and the anesthetic is desflurane.
摘要:
A device for mixing anesthetic vapor with anesthetic gas has a pressure limitation feature achieved in a simple manner. The device has a valve device (11), with which the evaporator is switched on and off. The valve device (11) is equipped with an overpressure release device (22).
摘要:
A care device and process are provided. The care device has a sensor module (11), which is to be placed directly on the patient (3) for picking up the patient's data, such as temperature, pulse and ECG. A first receiving means (13) is arranged in space in the vicinity of the patient (3) and is designed to pass on the measured data received from the sensor module (11). A mobile part (9) can be removed from the care device and provides wireless communication and a second receiving means (24) for establishing an alternative primary wireless link when the patient is removed from the care device.
摘要:
A filling device for an anesthetic evaporator has filling of an anesthetic evaporator is possible. To accomplish the object, an additional vent hole (36), which is opened immediately after the filling in order for excess anesthetic volume to be able to flow out of the filling device into the anesthetic tank (15) of the anesthetic evaporator (2), is provided within the filling device above a fluid channel (14), via which both the gas and liquid exchange takes place during the filling.

A process, system and device are provided for automatically recording pressure-vs.-volume curves during artificial respiration with a respirator. The inspiration pressure is increased during the supply of a breathing gas volume flow under the control of a control unit. The resulting breathing gas volume flow rate is detected and the volume is determined from the latter by integration. The control unit compares the breathing gas volume flow detected during the phase of expiration with a preselected set point and acts on an expiration valve (12) in the expiration line (8) by means of a controller in case of deviation from the set point in order to return the breathing gas volume flow to the set point.
摘要:
The invention relates to a respiration bag (1) which has at least one fold (2, 11) extending annularly over the bag (1). The respiration bag (1) can be bent in along this fold (2, 11). In this way, at least one depression results which leads to a reduced volume of the respiration bag (1). A flip over of the respiration bag from the bent-in position is prevented by sealing lips (10, 12) or additional mechanical holders which are applied from the outside to the at least one fold (2, 11). The respiration bag (1) remains stable in the bent-in position with reduced volume up to an inner pressure of 45 to 50 millibar. In this way, a respiration bag (1) for respiration volumes of different sizes is available in dependence upon, for example, whether respiration is to take place with ambient air or oxygen-enriched air or is dependent upon whether an adult or a child is to be respirated.

An apparatus for medical fluid delivery is to be improved for the sake of simple monitoring of the quantity of medical fluid delivered. For attaining this object, a safety device (15) with a patient model (16) is provided, which from past values and current values of the dosage rate of the medical fluid extrapolates a future medical fluid concentration (17) and switches off the dosage unit (10) for the medical fluid if the extrapolated medical fluid concentration (17) exceeds a predetermined limit value (14).
