Abstract

Παρέχεται χειρουργική κασέτα (200) που έχει ένα θάλαμο αισθήσεως πιέσεως υγρού (210) με μία σωληνοειδή προέκταση (σωλήνα) (240') που εκτείνεται δια μέσου ενός κενού (230') στο θάλαμο. Ο σωλήνας περιέχει τουλάχιστον μία θυρίδα (260') που ευχερώς επικοινωνεί (ούν) με το θάλαμο αισθήσεως της πιέσεως, που είναι προσαρμοσμένος ώστε να επιτρέπει τον καθαρισμό του αέρος από το θάλαμο κατά τη διάρκεια της αρχικής εμπυρευμάτησης της κασέτας, αλλά έχοντας ένα τέτοιο μέγεθος ώστε φυσαλίδες αέρος που εισέρχονται στη σωληνοειδή προέκταση δεν μπορούν εύκολα να ρεύσουν μέσα στο θάλαμο. Η σωληνοειδής προέκταση περαιτέρω περιέχει ένα μειωμένης διαμέτρου τμήμα (241) που δημιουργεί μία διαφοροποίηση πιέσεως προς τα επάνω και προς τα κάτω μίας συσκευής περιορισμού ροής (242). Η διαφοροποίηση της πιέσεως δημιουργεί ροή δια μέσου του θαλάμου κάτω από συμβάντα υψηλής ροής υγρού και ταραχώδους ροής υγρού.
