Die Erfindung betrifft eine Vorrichtung zur dynamischen Darstellung der Druck-Volumen- bzw. der Druck-Flächen-Beziehungen der Herzventrikel im menschlichen Herzen.The invention relates to a device for the dynamic representation of the pressure-volume or pressure-area relationships of the ventricles in the human heart.
Solche Vorrichtungen werden z.B. in der Kardiochirurgie bei der Einschätzung der therapeutischen (perioperativen) Versorgung von Patienten benötigt, um den Zustand der Herztätigkeit hinsichtlich der Druck-Volumentätigkeit des Herzens zu klassifizieren. Die Abhängigkeit zwischen der Länge und der Spannung eines Muskels entspricht am Herzen der Beziehung zwischen Ventrikelvolumen und Ventrikeldruck. Entscheidend für die weitere Behandlung ist die Fragestellung, ob auf die allgemeine Herztätigkeit durch Zufuhr von Volumen bzw. durch Stärkung der Herzkraft mittels Katecholamine bzw. einer geeigneten Kombination dieser Mittel Einfluß genommen werden muß.Such devices are required, for example, in cardiac surgery when assessing the therapeutic (perioperative) care of patients in order to classify the state of cardiac activity in terms of the pressure-volume activity of the heart. The relationship between the length and tension of a muscle corresponds to the relationship between ventricular volume and ventricular pressure in the heart. The decisive factor for further treatment is the question of whether general cardiac activity needs to be influenced by supplying volume or by strengthening cardiac strength using catecholamines or a suitable combination of these agents.
Die Anwendung dieser Vorrichtung bietet sich weiterhin in medizinischen Bereichen an, wo z.B. auf Grund minimal-invasiver Operationsmethoden eine Einschätzung der Herztätigkeit von Interesse ist, jedoch nicht direkt am offenen Thorax durchgeführt werden kann. Die minimal-invasiven Operationsmethoden bringen in vielen Bereichen ein vermindertes Operationsrisiko. Mit der hier beschriebenen Vorrichtung zum On-Line Monitoring der Herztätigkeit wird der fehlenden visuellen Einschätzung bei minimal-invasiven Eingriffen eine Alternative geboten. Neben der visuellen Einschätzung existieren bisher keine Möglichkeiten mit einer der Erfindung zugrundeliegenden Genauigkeit, so daß sich der praktische Einsatz der bisherigen Methoden im genannten Anwendungsbereich nicht bewährt hat.The use of this device is also suitable in medical areas where, for example, an assessment of cardiac activity is of interest due to minimally invasive surgical methods, but cannot be carried out directly on an open chest. Minimally invasive surgical methods reduce the risk of surgery in many areas. The device described here for online monitoring of cardiac activity offers an alternative to the lack of visual assessment in minimally invasive interventions. Apart from visual assessment, there are currently no options with the level of accuracy that the invention is based on, so that the practical use of the previous methods has not proven successful in the area of application mentioned.
Der Erfindung liegt die Aufgabe zugrunde, als Interpretationskomponente dem Arzt zur Verfügung zu stehen und die grundsätzlich mit einer medizinischen Behandlung verbundenen Risiken zu minimieren.The invention is based on the task of being available to the doctor as an interpretation component and of minimizing the risks fundamentally associated with medical treatment.
Ein Ausführungsbeispiel der Erfindung wird im folgenden näher beschrieben.An embodiment of the invention is described in more detail below.
In diesem Beispiel wird die Vorrichtung für die Behandlung von Patienten im Rahmen einer Herzoperation eingesetzt. Im Rahmen der perioperativen Versorgung ist die folgende Fragestellung zu beantworten:In this example, the device is used to treat patients during cardiac surgery. The following question must be answered as part of perioperative care:
In welchem Rahmen besteht Volumenmangel bzw. muß durch den Einsatz von Katecholaminen die Herzkraft gestärkt werden?To what extent does volume deficiency exist or does cardiac strength need to be strengthened through the use of catecholamines?
Die Vorrichtung ist in diesem Beispiel als eine Kombination von mindestens drei Geräten ausgeführt:In this example, the device is designed as a combination of at least three devices:
1. Einem Gerät, das als Interpretationskomponente fungiert und das Kern-1. A device that acts as an interpretation component and the core
stück der Erfindung darstellt. Dieses Intelligente Werkzeug ist mit einem für den Einsatz im medizinischen Bereich geeigneten Gehäuse versehen. piece of the invention. This intelligent tool is provided with a housing suitable for use in the medical field.
2. Einem Gerät zur Erfassung der patientenspezifischen Vitalparameter. Hierzu wird in diesem Ausführungsbeispiel ein Patientenmonitoringsystem verwendet, wie es gebräuchlicherweise auf Intensivstationen eingesetzt wird. Dieses Patientenmonitoringsystem verfügt über eine geeignete Datenschnittstelle, über welche die patientenspezifischen Meßwerte in das Intelligente Werkzeug übernommen werden können.2. A device for recording patient-specific vital parameters. In this example, a patient monitoring system is used for this purpose, as is commonly used in intensive care units. This patient monitoring system has a suitable data interface via which the patient-specific measured values can be transferred to the intelligent tool.
3. Einem Echokardiographen mit einem Meßwertaufnehmer, der während der kardiologischen Operation in die Speiseröhre eingeführt wird und einen auswertbaren Ultraschallwert hinsichtlich der Größe und der dynamischen planimetrischen Änderungen der Herzventrikel liefert.3. An echocardiograph with a transducer that is inserted into the esophagus during cardiological surgery and provides an evaluable ultrasound value regarding the size and dynamic planimetric changes of the heart ventricles.
Das Gehäuse des Intelligenten Werkzeuges kann zum Beispiel eine Vorrichtung zur Befestigung an einem Infusionsständer umfassen. Auf der Frontseite befindet sich ein Display, welches zur Darstellung von Information geeignet ist. Desweiteren besteht die Möglichkeit, mittels der Tastatur Entscheidungen des Intelligenten Werkzeuges zu bestätigen. Integriert ist ein Einplatinenrechner einschließlich der entsprechenden Module für die Speicherung von Informationen.The housing of the intelligent tool can, for example, include a device for attachment to an infusion stand. On the front there is a display suitable for displaying information. It is also possible to confirm decisions made by the intelligent tool using the keyboard. A single-board computer is integrated including the corresponding modules for storing information.
Am Intelligenten Werkzeug befinden sich Kabelanschlüsse bzw. Kabel zur Stromversorgung sowie zur Verbindung mit dem Patientenmonitoringsystem und dem Echokardiographen. Es verfügt außerdem über eine optische und akustische Signaleinheit.The intelligent tool has cable connectors or cables for the power supply and for connecting to the patient monitoring system and the echocardiograph. It also has an optical and acoustic signal unit.
