METHOD AND DISINFECTION DEVICE FOR DISINFECTING A STORAGE AND DRYING CABINET OF INVASIVE AND REUSABLE MEDICAL DEVICES.

DESCRIPTION OF THE INVENTION

The present invention fits into the technical sector of the storage and drying of reusable invasive medical devices, in particular of the disinfection and disinfection means of storage and drying cabinets configured to house and dry such medical devices.

Reusable invasive medical devices can consist of any instrument or apparatus, intended to be used in humans for the purpose of: diagnosis, control or surgery by total or partial penetration into the body through an orifice or a body surface that can be reused after washing and disinfection. In fact, after using a reusable invasive medical device, the latter must first of all be washed, with water and other detergents, to allow for subsequent disinfection. because water promotes bacterial proliferation, it must be dried and stored in an environment that prevents bacterial proliferation until its preparatory disinfection for further use. There? ? of particular importance for a variety of reusable invasive medical devices which include a series of internal channels which must be ensured to be aseptic when used. Among these we can cite, for example, diagnostic and control probes such as endoscopes, laparoscopes, thoracoscopes, cytoscopes, urethrenoscopes, nephroscopes, arthroscopes. Said reusable invasive medical devices, henceforth referred to in this document also only as ?medical devices? are regulated by Regulation (EU) 2017/745 of the European Parliament and of the Council of 5 April 2017.

? a cabinet (200) for storing and drying reusable invasive medical devices is known (see Fig. 1), which comprises: a technical housing (2); at least one storage and drying housing (3) for housing at least one invasive and reusable medical device; at least one door configured to close said technical compartment (2) and each foreseen storage and drying compartment (3); a drying circuit (35) comprising:

said at least one storage and drying housing (3); a first duct (5) for conveying air; a plurality? of gaps comprising a first end gap (6) and a second end gap (7); in which, when ? provided only a housing (3) for storage and drying, the first terminal cavity (6) ? disposed between, and in communication with, the first duct (5) and with said only one storage and drying housing (3) and the second terminal interspace (7) ? disposed between, and in communication with, said only one storage and drying housing (3) and said technical housing (2), and in which, when? expected a plurality? of housings (3) for storage and drying, called plurality? of interspaces further includes a plurality? of intermediate cavities (8); in which the first terminal gap (6) ? disposed between, and in communication with, the first duct (5) and the storage and drying housing (3) of said plurality? of storage and drying compartments (3) which ? placed distal to the technical housing (2), and the second terminal interspace (7) ? arranged between, and in communication with, the storage and drying housing (3) which is? arranged proximally to said technical housing (2) and said technical housing (2); and between two neighboring storage chambers (3) of the plurality? of storage bays (3) ? arranged a relative intermediate gap (8) of said plurality? of intermediate cavities (8). This storage and drying cabinet (200) further comprises: a filter (9), arranged in the technical housing (2) and having relative holes of dimensions smaller than or equal to 0.3 micrometres, in communication with the first duct (5) ; and a first conveying device (10), arranged in the technical housing (2) in communication with the filter (9), and operable to convey air, from the technical housing (2) into the filter (9) and, consequently, into the drying circuit (35) in a first conveying direction from the first duct (5) to the second interspace. This?, in order to dry with air filtered by said filter (9), and therefore ? bacteriologically clean, such medical devices while they are stored in the at least one storage compartment.
