«ΑΝΤΙΜΙΚΡΟΒΙΑΚΗ ΧΡΗΣΗ ΕΝΟΣ ΣΥΝΘΕΤΟΥ ΙΝΩΔΟΥΣ “ANTIMICROBIAL USE OF A COMPOSITE FIBER
ΥΛΙΚΟΥ ΠΟΛΥΤΕΡΕΦΘΑΛΙΚΟΥ ΑΙΘΥΛΕΝΙΟΥ ΚΑΙ ΙΟΝΤΩΝ OF ETHYLENE POLYTEREPTHALATE MATERIAL AND IONS
ΧΑΛΚΟΥ ΣΕ ΜΟΝΑΔΕΣ ΔΙΑΧΕΙΡΙΣΗΣ ΑΕΡΑ» COPPER IN AIR HANDLING UNITS"
Τεχνικό πεδίο Technical field
Η παρούσα εφεύρεση σχετίζεται με την ποιότητα του αέρα σε μονάδες διαχείρισης αέρα (fans, air-conditions) και ιδιαιτέρως με την εξουδετέρωση αερομεταφερόμενων δυνητικά παθογόνων βακτηρίων και ιών. The present invention relates to air quality in air handling units (fans, air-conditions) and particularly to the neutralization of airborne potentially pathogenic bacteria and viruses.
Τεχνική υποβάθρου Background technique
Τεχνικές που χρησιμοποιούνται σήμερα αφορούν κυρίως την χρήση φίλτρων HEPA (High Efficiency Particulate Air) σε αεραγωγούς μονάδων διαχείρισης αέρα. Μολονότι συγκρατούν τα μικρόβια, η ικανότητα πρόληψης μεταφοράς ιών έχει εξακριβωθεί σε λίγες μελέτες, διότι δεν αλληλεπιδρούν χημικά με τα ιικά σωματίδια, παρά μόνο συγκρατούν το υγρό που τα περιέχει. Techniques used today mainly concern the use of HEPA (High Efficiency Particulate Air) filters in air ducts of air handling units. Although they retain germs, the ability to prevent viral transmission has been verified in few studies because they do not chemically interact with viral particles, but only retain the fluid containing them.
Η παρούσα εφεύρεση χαρακτηρίζεται από εφάπαξ κόστος αγοράς και διαρκή μείωση του μικροβιακού και ιικού φορτίου σε καλυμμένες με αυτό επιφάνειες, όπως για παράδειγμα μέσα σε αεραγωγό ή μονάδα διαχείρισης αέρα. Η εγκατάστασή του βελτιώνει άμεσα την ποιότητα του αέρα, αφού φιλτράρει σωματίδια σκόνης και εξουδετερώνει βακτήρια και ιούς. The present invention is characterized by a one-time purchase cost and a permanent reduction of the microbial and viral load on surfaces covered with it, such as for example inside an air duct or air handling unit. Its installation immediately improves air quality, since it filters dust particles and neutralizes bacteria and viruses.
Η εφεύρεση είναι ένα ινώδες υλικού, το οποίο απαρτίζεται από πολλές ίνες που περιέχουν 97% έως 98% wt. πολυτερεφθαλικό αιθυλένιο και 2% έως 3% wt. χαλκό (κατιόντα ή και σωματίδια). Σημειώνεται πως τα κατιόντα χαλκού είναι Cu2+ που συνυπάρχουν με ανιόντα. Έχει διαπιστωθεί πειραματικά το ανωτέρω υλικό συγκεκριμένου πάχους 6mm μπορεί να κοπεί σε δισδιάστατο σχήμα, με πάχος 6 mm, και να τοποθετηθεί με ευκολία σε υφιστάμενες μονάδες διαχείρισης αέρα ως πρόσθετο φίλτρο. Επιπλέον επέρχεται μείωση του μικροβιακού φορτίου και ιδιαίτερα του ιικού φορτίου στην επιφάνειά του. The invention is a fibrous material, which consists of many fibers containing 97% to 98% wt. polyethylene terephthalate and 2% to 3% wt. copper (cations or particles). It is noted that the copper cations are Cu2+ that coexist with anions. It has been experimentally established that the above material of a specific thickness of 6mm can be cut into a two-dimensional shape, with a thickness of 6mm, and easily installed in existing air handling units as an additional filter. In addition, there is a reduction in the microbial load and especially the viral load on its surface.
Η εφεύρεση σχετίζεται με την αξιοποίηση των εγγενών αντιμικροβιακών και αντιιικών ιδιοτήτων του ιόντων χαλκού. Ένα κατιόν χαλκού (Cu<2+>) έχει ηλεκτρονιακή διαμόρφωση [Ar]3d<9>4s<0>. Η κυτταρική μεμβράνη των μικροβίων έχει ένα σταθερό ηλεκτρικό δυναμικό. Κάθε κατιόν έχει ένα ασύζευκτο ηλεκτρόνιο στο 3d ατομικό τροχιακό. Ερχόμενο σε επαφή με βακτήρια διαταράσσει το δυναμικό της μεμβράνης τους. Η μεμβράνη των βακτηρίων ανοίγει τρύπες, ιόντα χαλκού και τυχόν σωματίδια χαλκού μπαίνουν στο εσωτερικό του βακτηρίου, προσδένονται στα ένζυμα που είναι απαραίτητα για την επιβίωσή του. Ως αποτέλεσμα το βακτήριο πεθαίνει. Μελέτη (Evaluation of in vitro activity of copper gluconate against SARS-CoV-2 using confocal microscopy-based high content screening) έχει αποδείξει την δράση των ιόντων χαλκού, έναντι του ιού SARS-CoV-2. The invention relates to the utilization of the intrinsic antimicrobial and antiviral properties of copper ion. A copper cation (Cu<2+>) has an electronic configuration [Ar]3d<9>4s<0>. The cell membrane of microbes has a constant electrical potential. Each cation has an unpaired electron in the 3d atomic orbital. Coming into contact with bacteria, it disrupts their membrane potential. The membrane of the bacteria opens holes, copper ions and any copper particles get inside the bacterium, attach to the enzymes necessary for its survival. As a result the bacterium dies. A study (Evaluation of in vitro activity of copper gluconate against SARS-CoV-2 using confocal microscopy-based high content screening) has demonstrated the activity of copper ions against the SARS-CoV-2 virus.
Το ανωτέρω υλικό έχει επιφανειακή πυκνότητα 60 g/m<2>και χωρική πυκνότητα 10 kg/m<3>. Στον Πίνακα 1 παρουσιάζονται αποτελέσματα μετά από 30 min επαφής του υλικού με μία αρχική συγκέντρωση βακτηρίων και ιών. Τα αποτελέσματα αφορούν την εξωτερική επιφάνεια του υλικού. Στον Πίνακα 2 παρουσιάζονται αποτελέσματα μετά από 60 min επαφής του υλικού με μία αρχική συγκέντρωση βακτηρίων και ιών. Τα αποτελέσματα αφορούν την εξωτερική επιφάνεια του υλικού. The above material has a surface density of 60 g/m<2> and a bulk density of 10 kg/m<3>. Table 1 shows results after 30 min of contact of the material with an initial concentration of bacteria and viruses. The results refer to the outer surface of the material. Table 2 shows results after 60 min of contact of the material with an initial concentration of bacteria and viruses. The results refer to the outer surface of the material.
