Definitions
- the invention relates to a device and a method for administering xenon and / or a xenon-containing medium, in particular a xenon-containing gas mixture, to a patient, the patient using an inhalation circuit and a cardio-pulmonary bypass circuit (CPB- Circuit) is connected.
- a cardio-pulmonary bypass circuit CPB- Circuit
- administration should be understood to mean whatever application, administration, delivery, etc. of xenon or a xenon-containing medium to (one) patient.
- Xenon is a rare noble gas that occurs in the earth's atmosphere. Obtaining it - by means of cryogenic air separation - is comparatively complex and expensive. Xenon has both a proven anesthetic effect and a protective effect against neurotoxic events. For example, open heart surgery has a comparatively high risk of causing a neurotoxic event. In such operations, the heart-lung (blood) circulation in the body is bridged and the patient is supplied with oxygen via an external membrane, a so-called oxygenator. This application is also known as Cardio Pulmonary Bypass (CPB).
- CPB Cardio Pulmonary Bypass
- open heart surgery proceeds as described below.
- the patient is first ventilated using a ventilator and anesthesia machine.
- the patient's tissue can already be flooded with xenon.
- the cardiovascular system is then bridged and the oxygenator connected.
- xenon can enter the patient's tissue via the aforementioned oxygenator.
- the fan is or can be switched off while the CPB circuit is operating.
- the CPB circuit switches back to the ventilator or inhalation circuit.
- the patient can preferably be supplied with xenon - via the inhalation circuit.
- xenon is very expensive, efforts are being made to implement the above-described procedure in a manner which makes it possible to keep the consumption of xenon as low as possible.
- the object of the present invention is to provide a generic device and a generic method for administration of xenon and / or a xenon-containing medium, in particular a xenon-containing gas mixture, to a patient, by means of which a controlled addition of xenon or a xenon-containing medium can be realized in the inhalation and / or CPB circuit.
- a generic device which a) at least one source for xenon and / or for a xenon-containing medium, b) at least one supply unit for xenon and / or for a xenon-containing medium in the inhalation circuit and in the CPB circuit, c) at least one dosing unit for administration of xenon and / or a medium containing xenon into the inhalation circuit and into the CPB circuit, and d) at least one analysis unit for determining the xenon content in the inhalation circuit and / or the CPB cycle includes.
- the method according to the invention is characterized in that a) the xenon content in the inhalation circuit and / or the CPB circuit is determined directly or indirectly and b) at least temporarily xenon and / or a xenon-containing medium from a source of xenon and / or for a medium containing xenon in the inhalation circuit and / or in the CPB circuit.
- the administration of xenon and / or a xenon-containing medium can be carried out via a control algorithm by comparing the measured xenon concentration with the set xenon concentration and, depending on the difference between the two concentration values, the dosage of the xenon and / or a xenon -containing medium.
- a safety mechanism or program is preferably provided which prevents xenon from being administered in an undesirable or harmful overdose in the inhalation circuit and / or CPB circuit or a desired or required O 2 - 5 concentration is undercut.
- the 0 2 minimum concentration can be set to 20%, which can prevent an O 2 undersupply (hypoxia).
- the xenon concentration in the inhalation line or in front of the oxygenator and / or in the expiration line or after the oxygenator can be determined 1.5.
- a patient P is ventilated by means of an anesthesia machine V via a line 1.
- the breathing gas stream exhaled by the patient P is fed back to the anesthesia machine V via the line 1 '.
- the patient P is represented by a membrane M - represented by the dashed line 13, which symbolizes a hose system through which the patient's blood is pumped through the oxygenator - with a CPB circuit - represented by the lines 2 and 2 ' - connected.
- the CPB cycle exists, for example? from a pump that feeds the gas that has already passed through the oxygenator to the oxygenator again, thereby creating a closed system. Since the gas (mixture) leaving the oxygenator is usually enriched with CO 2 , the gas (mixture) is passed through a CO 2 absorber and / or adsorber and not before it is returned to the oxygenator, preferably thereby reducing the C0 2 concentration.
- the measuring lines 6 and 7 Via a central control unit S, in which the required analysis and dosing functions are implemented, the measuring lines 6 and 7
- parameters of the inhalation and / or CPB circuit which are detected by means of appropriate measuring devices, can also be advantageously transmitted to the control unit S.
- Such parameters are, for example, the concentrations of other gases (mixtures), flow rates, pressures, temperatures, etc.
- the control unit S is connected via line 3 to a source X for xenon and / or a xenon-containing medium, in particular a xenon-containing gas mixture.
- the source X for xenon and / or a xenon-containing medium can contain suitable storage units for xenon and / or a xenon-containing medium in gaseous form, in liquid form and / or in the form of a solution, for example a saline solution.
- the xenon can also be present in the form of a dispenser for xenon, the dispenser comprising a gas (mixture), a liquid, a solid or a solution.
- control unit S can further - as shown in the figure - be assigned at least one further source G for a single or multi-component gas or gas mixture via line 8.
- the source G serves in particular for the storage and delivery of gas mixtures, such as air, oxygen, carbon dioxide, nitrogen oxide, anesthetic gases, voiatile anesthetics, etc.
- Design options for source G apply to the statements made with regard to source X.
- xenon or a xenon-containing medium in the desired concentration can be added to this or these via lines 4 and / or 5. This metering into the circuit or circuits can take place either at the same time or with a time delay.
- Control valve a and possibly a pump P1 are arranged, a medium exchange can take place between the inhalation circuit and the CPB circuit. This option is used in particular when the gas is no longer used in one of the circuits. For example, after the end of the CPB therapy, the gas (mixture) can be diverted into the inhalation circuit.
- the inhalation and the CPB circuit can be connected to a recovery or reprocessing unit W via lines 10 and 11, in which control valves b and c and possibly pumps P2 and P3 are also arranged.
- This serves to recover and, if necessary, reprocess xenon from the gas or fluid mixtures of the inhalation and / or CPB circuit.
- the xenon recovery takes place by means of suitable measures, such as filtering, absorption, adsorption, compression, etc.
- the xenon obtained in the recovery or reprocessing unit W is generally collected and reprocessed in the factory. It would be conceivable - provided the reprocessing unit is configured accordingly - but also the direct supply of the reprocessed xenon to the xenon source X via the dotted line 12.
- the invention enables xenon or a xenon-containing medium to be metered into the inhalation circuit and / or the CPB circuit at the same time or with a delay.
- the metering into one or both circuits can be program-controlled. This program control enables the administration of xenon or a xenon-containing medium to be carried out in a time-optimized manner.
- the administration of xenon or a xenon-containing medium and the administration of other gases (mixtures), which may need to be provided can only take place before the CPB therapy, exclusively during the CPB therapy or exclusively after the CPB therapy. Furthermore, almost any combination, such as before and during CPB therapy, is possible.
- a safety mechanism or program is preferably provided which prevents xenon from being administered in an undesired or harmful overdose in the inhalation circuit and / or CPB circuit or from falling below a desired or required 0 2 concentration becomes.
- xenon or a xenon-containing medium is only possible from a presettable or preset oxygen concentration value. If this oxygen concentration value is determined to be 90%, for example, and xenon is supplied to the circuit in an amount such that a xenon concentration of 60%, the remaining 40% in the circuit consist of 90% oxygen. As a result, the oxygen concentration within the system or circuit would be an uncritical 36%.
- the security program can also be used to ensure that oxygen is flushed before the administration of xenon or a xenon-containing medium, which ensures a sufficiently high and thus also sufficiently safe oxygen concentration.
- both circuits can be supplied from a common source for xenon or for the xenon-containing medium.
- unused xenon can be recovered from both circuits and / or xenon that is no longer required in one of the two circuits can be fed to the other circuit.
