Description

BESCHREIBUNG:DESCRIPTION:

Hand-Messgerät zur kontaktlosen, gleichzeitigen Messung von Temperatur und Puls im Gehörgang des Menschen für den klinischen Pflegedienst unter Verwendung der Infrarot - Messtechnik.Handheld measuring device for contactless, simultaneous measurement of temperature and pulse in the human ear canal for clinical care using infrared measuring technology.

Zum momentanen Zeitpunkt wird im Pflegedienst der Krankenhäuser zweimal am Tag bei jedem stationären Patienten die Temperatur und der Puls gemessen.At the moment, the hospital nursing service measures the temperature and pulse of every inpatient twice a day.

Technischer Stand:Technical status:

Bisher wurden mit Hilfe von Quecksilber, Quecksilberersatz, digitaler und elektronischer Messgeräte die Temperaturen des Körpers ermittelt. Die Messorte waren axelar, oral und rektal. Diese Messungen sind ungenau, Kosten - und Zeitaufwendig, sowie umweltfeindlich.Until now, body temperatures were determined using mercury, mercury substitutes, digital and electronic measuring devices. The measurement locations were axelar, oral and rectal. These measurements are inaccurate, costly and time-consuming, and harmful to the environment.

Das Pulsmessen geschah im Regelfall durch abtasten mit Fingerspitzen, unter zu Hilfenahme von Uhren.The pulse was usually measured by feeling with fingertips, with the help of watches.

In den vergangenen Jahren hat sich die Pulsoximetrie und die Temperaturmessung mit Hilfe von Infrarot - Messgeräten entwickelt.In recent years, pulse oximetry and temperature measurement using infrared measuring devices have developed.

Es gibt jedoch kein Gerät, das beide Messungen gemeinsam durchfuhren kann.However, there is no device that can perform both measurements together.

Der in den Schutzansprüchen angegebenen Erfindung liegt das Problem zugrunde, ein Messgerät fur den täglichen klinischen Pflegedienst zu schaffen, was die beiden Messvorgänge, das Temperatur- und Pulsmessen, zu einem Messvorgang vereinigt und die Messergebnisse per Knopfdruck dem Pflegepersonal vor Ort, am Patienten, zugänghch macht. Die Messgrössen Temperatur und Puls sind nach etwa 4 Sekunden am Gerät abzulesen.The invention specified in the claims is based on the problem of creating a measuring device for daily clinical care, which combines the two measuring processes, temperature and pulse measurement, into one measuring process and makes the measurement results available to the nursing staff on site, on the patient, at the push of a button. The measured values of temperature and pulse can be read on the device after about 4 seconds.

Das neue an dem angemeldeten Gerät ist, daß die Technik von Pulsmessung und Temperaturermittlung, also zwei unterschiedliche Infrarotmessungen, in einem Gerät vereint werden. Im Besonderen wurde die Pulsmessung, die bisher von Sender und Empfanger abhängig war, in einem Gerät vereint. Unterschiedlich zum momentanen technischen Stand der Pulsoximetrie, das nämlich der Infrarotsender und - empfanger sich gegenüber liegen, sind im angemeldeten Gerät der Sender und Empfänger in einem spitzen Winkel zueinander angeordnet.What is new about the registered device is that the technology of pulse measurement and temperature determination, i.e. two different infrared measurements, are combined in one device. In particular, the pulse measurement, which was previously dependent on the transmitter and receiver, has been combined in one device. Unlike the current technical state of pulse oximetry, in which the infrared transmitter and receiver are opposite each other, in the registered device the transmitter and receiver are arranged at an acute angle to each other.

Das Gerät ist als kleines Handmessgerät konzeptioniert und hat einen Messtrichter, der problemlos in den Gehörgang des Patienten eingeführt werden kann. Mit einem Knopfdruck wird der Messvorgang ausgelöst.The device is designed as a small hand-held measuring device and has a measuring funnel that can be easily inserted into the patient's ear canal. The measurement process is initiated at the push of a button.

Um die hygienischen Bedingungen zu erreichen, wird der Messtrichter, der in das Ohr eingeführt wird, mit einer Folie überzogen. Diese Folie kann über einen Mechanismus weitergerollt werden, sodaß jede Messung eine neue Folienschicht über dem Messtrichter hat.In order to achieve hygienic conditions, the measuring funnel that is inserted into the ear is covered with a film. This film can be rolled up using a mechanism so that each measurement has a new layer of film over the measuring funnel.

Temperaturmessung:Temperature measurement:

Die Messung erfolgt physikalisch nach dem Prinzip eines Pyrometers (Strahlungsthermometer). Die entsprechenden Meßaumehmer sind Stand der Technik. Prinzipiell wird mit einem photoelektrischen Detektor die Strahlungsmenge, die vom Meßobjekt abgestrahlt wird, gemessen. Diese Strahlungsmenge ist ein direktes Maß fur die Temperatur.Der notwendige Wellenlängenbereich des Detektors liegt je nach zu messendem Temperaturbereich zwischen 8 und 20 /tm (kann auch größer oder kleiner sein). Der Vorteil von Photoelektrischen Dedektoren ist die hohe Empfindlichkeit und die kurze Einstellzeit.The measurement is carried out physically according to the principle of a pyrometer (radiation thermometer). The corresponding measuring sensors are state of the art. In principle, the amount of radiation emitted by the object being measured is measured using a photoelectric detector. This amount of radiation is a direct measure of the temperature. The required wavelength range of the detector is between 8 and 20 /tm (can also be larger or smaller), depending on the temperature range to be measured. The advantage of photoelectric detectors is their high sensitivity and short response time.

Pulsmessung:Pulse measurement:

Durch den sich rythmisch ändernden Fluß ändert sich der Apsorptionsgrad des Blutes. Dieser beeinflusst die Reflektion des von einem Sender eingestrahlten Infrarotlichts. Gemessen wird die reflektierte Lichtmenge. D.h., jede Änderung der reflektierten Lichtmenge entspricht einem Pulsschlag. Für die Pulsmessung ist also ein Infrarot-Sender und ein -Empfänger notwendig.Die Wellenlänge von üblichen Infrarotsendedioden hegt bei ca 950 nm (kann auch größer oder kleiner sein).The rhythmically changing flow changes the absorption level of the blood. This influences the reflection of the infrared light emitted by a transmitter. The amount of light reflected is measured. This means that every change in the amount of light reflected corresponds to a pulse beat. An infrared transmitter and a receiver are therefore required to measure the pulse. The wavelength of standard infrared transmitter diodes is around 950 nm (can also be larger or smaller).

Der Hauptvorteil dieses Messgerätes liegt in der starken Aufwandsreduzierung im Pflegedienst, was sich direkt auf die Pflegekosten der Krankenhäuser auswirkt und diesen Bereich des Pflegedienstes um einen Faktor von ca. 10 bis 20 entlastet.The main advantage of this measuring device is the significant reduction in the effort required for nursing services, which has a direct impact on hospitals’ nursing costs and reduces the burden on this area of nursing services by a factor of around 10 to 20.

Ein weiterer Vorteil liegt in der kontaktlosen Messung, da kein Hautkontakt mehr zwischen Pflegepersonal und Patienten zustande kommt.Another advantage is the contactless measurement, as there is no longer any skin contact between nursing staff and patients.
