Abstract

Σε μίαν μέθοδο μέτρησης της πυκνότητας μίας ουσίας όπως γλυκόζης σε ένα δείγμα υγρού όπως αίματος ή διάμεσου υγρού, παρέχεται μία συσκευή μέτρησης έχουσα ένα τμήμα αισθητήρα εργασίας (6b), ένα δεύτερο τμήμα αισθητήρα εργασίας (8b) και ένα τμήμα αισθητήρα αναφοράς (4b). Το δείγμα υγρού τοποθετείται στην συσκευή μέτρησης και ένα ηλεκτρικό ρεύμα ανάλογο προς την πυκνότητα της ουσίας στο δείγμα υγρού μετράται σε έκαστο τμήμα αισθητήρα (6b, 8b). Τα ηλεκτρικά ρεύματα συγκρίνονται προς εξακρίβωση της διαφοράς. Εάν η διαφορά είναι μεγαλύτερη από ένα προκαθορισμένο κατώφλιο, δίδεται μία ένδειξη σφάλματος. Μία ταινία δοκιμής μίας χρήσεως με δύο αισθητήρες εργασίας (6b, 8b) επίσης αποκαλύπτεται.In a method of measuring the density of a substance such as glucose in a fluid sample such as blood or interstitial fluid, a measuring apparatus having a working sensor portion (6b), a second working sensor portion (8b) and a reference sensor portion (4b) are provided. The liquid sample is placed in the measuring apparatus and an electrical current proportional to the density of the substance in the liquid sample is measured in each sensor section (6b, 8b). The electric currents are compared to determine the difference. If the difference is greater than a predetermined threshold, an error indication is given. A disposable test strip with two working sensors (6b, 8b) is also disclosed.
