Abstract
Description
Stand der TechnikState of the art
Im medizinischen Alltag besteht häufig die Anforderung, die Konzentration bzw. das Vorhandensein von medizinisch relevanten Substanzen in Körperflüssigkeiten zu ermitteln. Dabei kann es sich sowohl um körpereigene Substanzen mit indikativer Wirkung, wie auch um therapeutisch wirksame Substanzen handeln. Zu diesem Zweck müssen die betreffenden Körperflüssigkeiten dem Patienten entnommen und labortechnisch untersucht werden.In medical practice there is often the requirement to determine the concentration or the presence of medically relevant substances in body fluids. These may be both body-own substances with indicative effect, as well as therapeutically active substances. For this purpose, the relevant body fluids must be removed from the patient and laboratory-examined.
Nachteile heutiger VerfahrenDisadvantages of today's procedures
Heutige Verfahren beruhen darauf, dass die Körperflüssigkeiten mit Hilfe von Injektionsnadel entnommen werden, um diese dann extern labortechnisch zu untersuchen. Durch die Entnahmen mit Hilfe von Injektionsnadeln kommt es zwangsläufig zur Schädigung der Gefäßwände. Ebenso ist die Entnahmemenge begrenzt, da beispielsweise Blut nur in natürlichen Mengen nachgebildet wird. Das hat zur Folge, dass die Entnahmehäufigkeit wie auch Entnahmemenge von Körperflüssigkeiten natürlichen Limitierungen unterliegt. Die begrenzte Entnahmehäufigkeit und die zeitaufwendige Laboruntersuchung können in bestimmten klinischen Situationen zu Problemen bei der Überwachung von Patienten führen.Today's procedures are based on the fact that the body fluids are removed with the help of injection needle, in order to examine these then externally laboratory-technically. Removal with the help of hypodermic needles will inevitably damage the vessel walls. Likewise, the removal amount is limited because, for example, blood is replicated only in natural quantities. This has the consequence that the removal frequency as well as removal amount of body fluids is subject to natural limitations. The limited frequency of collection and time-consuming laboratory testing may cause problems in patient monitoring in certain clinical situations.
Beschreibungdescription
Die beschriebene Vorrichtung misst klinisch relevante Substanzen innerhalb der Gefäße und übermittelt die gewonnenen Daten kontaktlos an eine geeignete Empfangsvorrichtung. Die so gewonnenen Messdaten stehen durch die Empfangsvorrichtung für eine beliebige Weiterverarbeitung zur Verfügung.The device described measures clinically relevant substances within the vessels and transmits the data obtained without contact to a suitable receiving device. The measurement data thus obtained are available through the receiving device for any further processing.
Aufbau und FunktionsweiseStructure and operation
Das Verfahren beruht darauf, dass an der Oberfläche der Innenseite einer Gefäßprothese (
Die Vorteile des Verfahrens bestehen darin, dass keine Entnahme von Körperflüssigkeiten erforderlich ist, da die Messung im Gefäß selbst erfolgt. Der Messvorgang kann beliebig oft wiederholt werden, was eine kontinuierliche und kontaktlose Überwachung des Patienten gestattet. Aufgrund der verwendeten RFID-Technologie benötigt die in der Gefäßprothese angebrachte Messanordnung keine Spannungsversorgung in Form einer Batterie, da die erforderliche Energie für die Zeitdauer des Messvorganges von außen kontaktlos zugeführt wird.The advantages of the method are that no removal of body fluids is required because the measurement takes place in the vessel itself. The measuring process can be repeated as often as required, which allows continuous and contactless monitoring of the patient. Due to the RFID technology used, the measuring arrangement mounted in the vascular prosthesis does not require a voltage supply in the form of a battery, since the energy required for the duration of the measuring procedure is supplied without contact from the outside.
