Abstract
Description
Die vorliegende Erfindung betrifft eine Patienten-Heizauflage, umfassend eine Heizmatte oder Heizdecke aus einem Wärme isolierenden Material und mindestens ein in die Heizdecke oder Heizmatte integriertes Heizelement und mindestens einen Temperatursensor.The The present invention relates to a patient heating pad comprising a heating mat or electric blanket made of a heat insulating Material and at least one integrated into the heating blanket or heating mat Heating element and at least one temperature sensor.
Eine
derartige Patienten-Heizauflage ist beispielsweise durch die
Bei medizinischen Untersuchungen, Operationen und/oder Überwachungen von Patienten auf Intensivstationen werden Patienten-Heizauflagen eingesetzt. Wichtig ist es, dass die Temperatur der Heizauflage durch den Arzt oder das Pflegepersonal richtig eingestellt wird. Hierfür sind entsprechende Regeleinrichtungen und mit diesen in Verbindung stehende Temperatursensoren vorgesehenen, um den Heizstrom durch das Heizelement zu kontrollieren und einzustellen.at medical examinations, operations and / or monitoring of patients in intensive care units will be patient heating pads used. It is important that the temperature of the heating pad properly adjusted by the doctor or nursing staff. For this purpose, appropriate control devices and with these provided in conjunction with temperature sensors to the heating current to control and adjust by the heating element.
Problematisch ist es, dass die Temperatursensoren und manche verwendete Heizelemente nicht für bildgebende diagnostische Anwendungen geeignet sind, weil sie nicht aus im Sinne dieser Anwendungen transparentem Material hergestellt sind.Problematic it is that the temperature sensors and some used heating elements are not are suitable for imaging diagnostic applications, because they are not made of transparent material in the sense of these applications are made.
Daher wird in der oben genannten Publikation vorgeschlagen, zur Regelung der Heizleistung nicht nur einen mit der Heizvorrichtung in Verbindung stehenden Temperatursensor heranzuziehen, sondern mindestens ein weiteres Temperatursignal über ein Körpermerkmal des Patienten auszuwerten. Die Temperaturenmessung an der Hautoberfläche des Patienten ist recht ungenau und für die Regelung der Heizvorrichtung eher ungeeignet.Therefore is proposed in the above publication, for regulation the heating power not only a related to the heater Temperature sensor, but at least one other Temperature signal on a body feature of the patient evaluate. The temperature measurement on the skin surface the patient is quite inaccurate and for regulating the heater rather unsuitable.
Eine Temperaturmessung am Patienten durchzuführen, bedeutet einen erhöhten Aufwand bedeutet beziehungsweise stört die medizinische Anwendung.A Temperature measurement on the patient, means an increased effort means or disturbs the medical application.
Daher liegt der Erfindung die Aufgabe zu Grunde, die bekannte Heizauflage dahingehend zu verbessern, dass die Handhabung erleichtert ist und die Anwendung bildgebender diagnostischer Verfahren nicht gestört wird.Therefore The invention is based on the object, the known heating pad be improved so that the handling is easier and the Application of diagnostic imaging procedures not disturbed becomes.
Diese Aufgabe wird durch eine Patienten-Heizauflage gemäß Patentanspruch 1 gelöst.These Task is a patient heating pad according to claim 1 solved.
Zur Anwendung bildgebender diagnostischer medizinischer Verfahren ist das mindestens eine Heizelement durch Karbonfasern ausgebildet. Die elektrischen Anschlüsse der Karbonfasern sind vorzugsweise durch mehrfach genähte Metallfäden ausgebildet und erstrecken sich über nahezu die gesamte Breite der Heizauflage. Diese Erstreckung und der sich daraus ergebende elektrische Stromfluss führt zu einer gleichmäßigen Erwärmung der Heizauflage. Das in die Patienten-Heizauflage integrierte Heizelement ist gegenüber dem ursprünglich gefertigten Heizelement zusammengeklappt. Daraus ergibt sich eine doppelte Lage aus Karbonfasern. Wenn das Heizelement mit Wechselspannung betrieben wird, gleichen sich die elektromagnetischen Felder der beiden Lagen aus, so dass die resultierende Feldstärke sehr gering ist. Trotz des Betriebes mit Wechselspannung entsteht ein Verhalten wie bei einer Gleichspannung.to Application of diagnostic imaging medical procedure is the at least one heating element is formed by carbon fibers. The electrical connections of the carbon fibers are preferably formed by multiple stitched metal threads and extend over almost the entire width of the Heating pad. This extension and the resulting electrical Current flow leads to a uniform Heating the heating pad. The in the patient-heating pad integrated heating element is opposite to the original one made heating element folded. This results in a double layer of carbon fiber. When the heating element with AC voltage operated, the electromagnetic fields of the two are alike Lay out, so the resulting field strength is very low is. Despite the operation with AC voltage creates a behavior as with a DC voltage.
Die erfindungsgemäße Patienten-Heizauflage ist in einen Auflagebereich und einen Temperaturmessbereich unterteilt. In dem Temperaturmessbereich wird die Messung am Patienten simuliert. Der übrige Bereich der Patienten-Heizauflage kann somit frei von Temperatursensoren und elektrischen Anschlüssen gehalten werden. Der Temperaturmessbereich ist vorteilhafter Weise vollständig in die Patienten-Heizauflage integriert.The Patient heating pad according to the invention is in divided a support area and a temperature measuring range. In the temperature measuring range, the measurement on the patient is simulated. The remaining area of the patient heating pad can thus be free held by temperature sensors and electrical connections become. The temperature measuring range is advantageously complete integrated into the patient heating pad.
Weitere vorteilhafte Weiterbildungen der Erfindung sind in den Patentansprüchen beschrieben.Further advantageous developments of the invention are in the claims described.
Ein bevorzugtes Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird nachfolgend anhand der Figuren der Zeichnung beschrieben.
