Abstract

Σύστημα χορήγησης ρευστού που περιλαμβάνει έναν πρώτο περιέκτη ρευστού, που περιέχει ρευστό έγχυσης για ασθενή. Ο πρώτος περιέκτης ρευστού έχει έξοδο και σωλήνα ρευστού συνδεδεμένο στην έξοδο. Ένας δεύτερος περιέκτης ρευστού ασκεί πίεση στον πρώτο περιέκτη ρευστού για να εξωθήσει το ρευστό εκτός του πρώτου περιέκτη και εντός του σωλήνα με τον επιθυμητό ρυθμό ροής. Ένας αισθητήρας ροής είναι συνδεδεμένος στον δεύτερο περιέκτη ρευστού και ένας αισθητήρας ροής είναι συνδεδεμένος με το σωλήνα. Ο αισθητήρας πιέσεως παρέχει σήματα πιέσεως σε επεξεργαστή, αποκρινόμενος στην πίεση στο δεύτερο περιέκτη ρευστού, ενώ ο αισθητήρας ροής παρέχει σήματα ροής στον επεξεργαστή, αποκρινόμενος στη ροή ρευστού μέσω του σωλήνα. Ο επεξεργαστής παρακολουθεί το ρυθμό ροής και ελέγχει τον κύκλο λειτουργίας ενός ενεργοποιητή ελέγχου κατάντη ροής για να διατηρείται ο επιθυμητός ρυθμός ροής. Ο επεξεργαστής μπορεί επίσης να καθορίζει την κατάντη αντίσταση του συστήματος, μεταβάλλοντας το ρυθμό ροής γύρω από τον επιλεγόμενο ρυθμό ροής, λαμβάνοντας τα σήματα πιέσεως και ροής και υπολογίζοντας τη μεταβολή της πιέσεως ως προς την αντίστοιχη μεταβολή στο ρυθμό ροής, προκειμένου να προκύψει η μέτρηση της αντίστασης ρευστού.
