摘要： An overflow trap on a reservoir for liquid anesthetics with at least one inlet conduit for filling and an overflow conduit for overflow which both open at its side wall. The entering of anesthetic liquid from a feed tank through the inlet and the overflow of anesthetic due to shifts or rocking of the liquid level is prevented. For this purpose, the inlet conduit and the overflow conduit are slanted toward the bottom of the reservoir and they have openings close to a wall of the reservoir which is opposite to the inlet and the overflow openings of the conduits.

摘要： The invention is directed to an arrangement for adding liquid anesthetic medium to the respiratory gas to be directed to a patient and is applicable to a closed respiratory system wherein an adequate quantity of the anesthetic medium must be supplied in a small respiratory gas volume and is also applicable to an open system wherein large quantities of anesthetic medium are required. The arrangement of the invention includes a plurality of tanks containing anesthetic mediums and a selection switch which can be selectively switched to any one of the tanks. A pump is located after the selection switch and a change-over switch permits switching the anesthetic medium from the pump to an anesthetic medium vaporizer and a swirl chamber. The anesthetic medium is vaporized in the vaporizer and then conducted at high concentration into the respiratory gas directed to the patient. The gas can be guided in a closed system. In the swirl chamber, the anesthetic medium is vaporized into the fresh gas flow which then is conducted to the patient in the form of respiratory gas. A control arrangement monitors and, with data from corresponding measuring devices, controls the preselected sequences.

摘要： A receiving arrangement is disclosed for filling an anaesthetic medium from a supply vessel into the charging chamber of an anaesthetic apparatus. The supply vessel is connectable to the arrangement by means of a coupling piece. The arrangement includes a receiving structure having an input opening for receiving the coupling piece therein and a connecting part disposed adjacent the receiving structure. The connecting part includes channels communicating with the charging chamber for conducting the anaesthetic medium to the latter. A closure piece is slidably mounted in the receiving structure to slide between a first position opposite the ports and a second position whereat the closure piece is displaced away from the ports. A resilient biasing spring biases the closure piece into the first position. A drive moves the receiving structure between a rest location whereat the closure piece seals the ports with respect to the ambient and an actuating location whereat the receiving structure and the closure piece are displaced away from the ports. The receiving structure can now receive the coupling piece thereby causing the closure piece to be displaced to its second position. The coupling piece and the connecting part conjointly define a connecting interface whereat the anaesthetic medium flows from the coupling piece into the channels when the structure is returned to the rest location with the coupling piece inserted therein. A blocking piece blocks the entry of the coupling piece through the opening when the receiving structure is in its rest location.

摘要： The invention is directed to a filling arrangement for filling and emptying an anesthetic vaporizer with an anesthetic liquid from a supply vessel via a filling channel and a venting channel. The filling arrangement includes a connecting piece for connecting the arrangement to the anesthetic vaporizer and has a blocking device mounted in a conduit member which includes the filling channel and venting channel. The filling arrangement is improved so that it can be reliably handled with anesthetic liquids having a low boiling point. For this purpose, the blocking device includes a temperature-sensitive switching member which enables the filling channel to be opened below a preselected limit temperature and to be closed above this preselected temperature. The preselected temperature is below the boiling point of the anesthetic liquid.

摘要： A device for controlling respirating gas in an anaesthesia or respiratory apparatus contains a multiplicity of control elements. Each control element has a control chamber with control lines and a respirating gas chamber with respiratory gas lines, the control chamber and respirating gas chamber being separated from one another by a closure element. The respirating gas chambers and the control chambers are combined with each other so that as few component parts as possible have to be disassembled and assembled to facilitate cleaning and disinfection. For this purpose, the control chambers are combined into one control block and the respirating gas chambers are combined into one respirating gas block, such that the two blocks can be coupled together into a unit with a common sealing plate defining closure elements. The control chambers and respirating gas chambers are separated and yet are arranged so that the control chambers coact with corresponding ones of the respirating gas chambers.

摘要： The invention is directed to a method for simulating and demonstrating the gas exchange during ventilation wherein the breathing gas is influenced with respect to its constituents by changing the portion of at least one breathing gas component metered to the carrier gas. The method permits simulation of physiological functions occurring during anesthesia such as the uptake and release of anesthetic agents. For this purpose, an anesthetic agent is admixed to the breathing gas and this anesthetic gas mixture is conducted through a reservoir filled with organic oil to simulate the anesthetic agent uptake and release by the human or animal body.
