Claims (3)

1. Biosensor mit einem Schlitz, der einen Schlüsselcode­ streifen und einen Untersuchungsstreifen aufnehmen kann und der ferner über eine Reaktionsgrube und mehrere mit dieser in Kontakt stehende Elektroden verfügt, ferner mit einer Spannungsquelle, einem Messverstärker, einem beschreibbaren Speicher und einem Mikroprozessor, wobei die Spannungsquelle eine Betriebsspannung an eine Elektrode des Untersuchungs­ streifens liefert und wobei der Messverstärker mit einer an­ deren Elektrode desselben verbunden ist, wobei dann, wenn ein einen zu analysierenden Stoff enthaltendes Fluid in die Reaktionsgrube getropft wird, ein einem Messstrom entspre­ chendes Ausgangssignal erzeugt wird, wobei der Schlüsselco­ destreifen vorab in den Schlitz gesteckt wird, damit der be­ schreibbare Speicher eine Anzahl von Parametern und eine Be­ triebsprozedur zum Speichern des Betriebs des Biosensors, die in einem EEPROM des Schlüsselcodestreifens gespeichert sind, lesen kann, wobei der Mikroprozessor dann auf die Be­ triebsprozedur und die Parameter reagiert, um mehrere Span­ nungen mit einer vorbestimmten Dauer zu bestimmen, wobei die Spannungen und die Dauern ebenfalls aus den im EEPROM des Schlüsselcodestreifens gespeicherten Daten erhalten werden; und wobei der Mikroprozessor den Messverstärker steuert, der mit vorbestimmter Zeit mehrere Ausgangssignale erzeugt, um das aus dem den zu analysierenden Stoff enthaltenen Fluid gemessene Analyseergebnis anzuzeigen, während aus dem im EEPROM des Schlüsselcodestreifens gespeicherten Daten auch ein durch den Messverstärker gesteuerter spezieller Parame­ ter erhalten wird.1. Biosensor with a slot that has a key code can strip and record an examination strip and which also has a reaction pit and several with this electrodes in contact, also with a Voltage source, a measuring amplifier, a writable Memory and a microprocessor, being the voltage source an operating voltage to an electrode of the examination stripes supplies and the measuring amplifier with one the electrode of which is connected, where if a fluid containing a substance to be analyzed into the Reaction pit is dropped, corresponds to a measuring current output signal is generated, the key co the first strip is inserted into the slot so that the be writable memory a number of parameters and a Be drive procedure for storing the operation of the biosensor, which are stored in an EEPROM of the key code strip are, can read, the microprocessor then on the loading drive procedure and the parameters responded to multiple span to determine with a predetermined duration, the Tensions and the duration also from the in the EEPROM of the Key code strip stored data can be obtained; and wherein the microprocessor controls the measurement amplifier that generates a plurality of output signals at a predetermined time the fluid contained in the substance to be analyzed display measured analysis result, while from the im Key code strip EEPROM stored data too a special parameter controlled by the measuring amplifier ter is obtained. 2. Biosensor nach Anspruch 1, gekennzeichnet durch einen in den Schlitz steckbaren Untersuchungsstreifen, der über eine Widerstandsschaltung zum Kalibrieren des Biosensors verfügt. 2. Biosensor according to claim 1, characterized by a Examination strips which can be inserted into the slot and which are above a resistance circuit for calibrating the biosensor features.   3. Biosensor nach Anspruch 1, dadurch gekennzeichnet, dass der Schlüsselcodestreifen ferner über eine Widerstandsschal­ tung zum Kalibrieren des Biosensors verfügt.3. Biosensor according to claim 1, characterized in that the key code strip also via a resistance scarf device for calibrating the biosensor.
