Abstract

Φίλτρον ανταλλαγής θερμότητας και υγρασίας περιλαμβάνει στρώμα υδροφοβικών μέσων μαζί με στρώμα υδροφιλικών μέσων. Το φίλτρο μπορεί να χρησιμοποιείται ιατρικώς στο άκρο ασθενούς συστημάτων ανοικτής αναπνοής με το υδροφιλικό μέσο μετά τον ασθενή στον δρόμον εκπνοής. Το υδροφοβικόν υλικόν εμποδίζει τη διέλευση σταγόνων νερού και σφαιριδίων νερού κατά γνωστόν τρόπον και έχει επίσης επαρκώς υψηλό σημείο φυσαλίδας για παγίδευση μικρο - οργανισμών. Το υδροφιλικόν υλικό συλλαμβάνει ατμόν νερού ο οποίος περνά μέσω του υδροφοβικού υλικού και έτσι επιτρέπει τη συγκράτηση περισσότερης υγρασίας από το φίλτρο. Η υγρασία αυτή συλλέγεται από τα εισπνεόμενα αέρια και εξυπηρετεί για παροχή πρόσθετης υγρασίας σε τέτοια εισπνεόμενα αέρια.ω
