Abstract

Το σύστημα αντλίας έγχυσης (1) περιλαμβάνει βηματικό κινητήρα (2) που συνδέεται σε εκκεντροφόρο άξονα (4) μέσω ζεύγους οδοντωτών τροχών υποπολλαπλασιασμού (6). Ο βηματικός κινητήρας (2) κινεί τον εκκεντροφόρο άξονα (4) με αρκετά έκκεντρα (8) τοποθετημένα πάνω σε αυτόν σε διάφορες θέσεις σε απόσταση μεταξύ τους γύρω από την περιφέρεια του άξονα (4). Αυτά τα έκκεντρα (8) εμπλέκονται συνδετικά με δακτύλους ακόλουθου (10) που συμπιέζουν διάφορα τμήματα σωλήνωσης ενδοφλέβιας (IV) στάγδην χορήγησης (12) που τρέχει παράλληλα με τον εκκεντροφόρο άξονα (4). Ασκός ενδοφλέβιας (IV) στάγδην χορήγησης (22) περιέχει υγρό που ρέει προς τους ασθενείς μέσω του σωλήνα (12). Ο σωλήνας (12) τοποθετείται με το χέρι μέσα στο μηχανισμό μέσω πλάκας ή θύρας σύλληψης (16). Με αποτέλεσμα το (IV) υγρό μέσα στη σωλήνωση (12) να ωθείται διαμέσου της αντλίας (1) σε ακριβώς ελεγχόμενους ρυθμούς που είναι ευθέως ανάλογοι με το ρυθμό βήματος του βηματικού κινητήρα.
