Abstract

The present certificate of addition of invention relates to a cupboard (12) forming a portable autoclave emitting UV-C radiation without any "shadows", reaching the totality of the surface of instruments (IN) to be disinfected for use by doctors, dentists and other health professionals, as well as aestheticians, manicurists or any professionals that act in any way directly or on specific points of the human body. For that purpose, the box (1) and cover (2) are separately provided with electroelectronic components then wrapped with a lining (11) made of fabrics or a plastic film, assembled in the form of a cupboard (12) that receives a transparent lens (13) made of a high UVC transmittance material at a central height of the box (1). The instrument (IN), which is suspended or hangs from a metal rod (14) in the box (1), is irradiated by UV-C radiation emitted by UV-C LEDs (9) and (6) mounted on both the inner surface of the top face (2d) of the cover (2) and the bottom (1f) of the box (1). If the cover (2) is opened during the predetermined sanitising cycle, an electromagnetic sensor (8) detects this movement and the UVC LEDs (6) and (9) are automatically switched off.

Description

“SET FOR ASSEMBLY AND STRUCTURING PORTABLE CABINET, WITH ELECTRO-ELECTRONIC ARRANGEMENT FOR DISINFECTION AND STERILIZATION SYSTEM OF HOSPITAL AND SIMILAR MEDICAL INSTRUMENTS” Certificate of Invention Addition of BR102022007633-2, deposited on 04/20/2022

[001] This descriptive report refers to the Certificate of Addition of Invention for the unprecedented assembly of a portable cabinet that is structured like an autoclave, functioning to direct the emission of UV-C light across the entire surface of the objects to be sterilized, sanitizing them completely.

Technique comments

[002] There is a huge concern, even more so nowadays, with the sterilization of instruments used by doctors, dentists and other health professionals, as well as beauticians, manicurists and any professionals who act by interfering in any way, directly or at specific points of the Human Body.

[003] The situation worsens especially if these instruments are housed in bags, briefcases and similar portable accessories, when the professional must travel to the location of the treatment to be offered and where he will not have devices intended for sterilization at his disposal. such as vats with hot water, ovens and autoclaves. Due to the emergence of diseases such as extremely strong, highly contagious flu, as well as other communicable illnesses, it is therefore essential that viruses, bacteria and other microorganisms are combatted.

[004] A proven effective application is UV-C light, whose waves are emitted by LED or lamp, promoting sterilization of objects and even the space of environments when coupled with ventilation, expanding the range of protection against harmful microorganisms, suspended in the air or deposited on handling objects.

[005] In this sense, the published patent application authored by the same inventor as the application to be described below can be cited. In this document BR 102020015902-2 cited here, called “BAG WITH SELF-SUPPORTANT UVC EMISSION SYSTEM FOR DISINFECTION AND SANITIZATION OF OBJECTS AND SAFETY SYSTEM”, a portable bag containing an electronic control circuit board for switching on and off by timing is protected. , UVC LED'S (13) mounted on a strip. An image of this document BR 102020015902-2 is inserted only as an example as figure 1 for the application to be described below. When the bag is closed, through its zipper, these LEDs (13), positioned on the inside of the upper part, light up and cause waves to fall on the instruments housed in it, sterilizing them. This action is indicated by an external, flashing LED (12). Once internal sterilization is complete, the UVC LEDs ( 13) are turned off by the timer and the pilot LED ( 12) is turned off, “warning” the user that they can open the bag without exposing themselves to radiation.

[006] Despite the high sanitizing capacity of the bag mentioned above being proven, during its use it was noticed that, because the instruments are sitting directly on the bottom, “shadows” may occur. By shadow we mean that UVC radiation does not reach the surface of these parts of the instruments that are precisely in contact with the bottom of the bag.

Purpose of the order

[007] As an evolution to this bag, a portable cabinet was developed by the same inventor of the patent application now proposed. which now has means to focus UVC radiation on the entire surface of the instruments housed in it without the possibility of shadowing.

[008] To this end, a box and its lid, injected in polymeric material, receive dedicated cutouts and conformations in the mold for fitting electronic components such as printed circuit boards for controlling UV-C LED boards, LED lights , on/off button and an electromagnetic lock. Box and lid are positioned to receive a covering, preferably made of fabric, with predefined cutouts according to the position of these assembled electronic components. When “dressed”, the box and lid become “souls” structured to form a cabinet with a hinged lid and internal corners to receive the support of a transparent lens, made with polymeric material with high UVC transmittance, positioned at an intermediate height. . In this transparent lens made with polymeric material with high UVC transmittance, the instruments to be sterilized are placed, which, as they are “suspended” in the middle of the cabinet, can receive UVC light emission from UV-C LEDs mounted both above, on the lid, as well as below, on the bottom of the box, thus being disinfected on its entire surface. The instruments can also be hung inside the cabinet, using a metal rod.

[009] Explained superficially, the cabinet and its assembly become better detailed.

[010] The image in figure 1, as already explained, belongs to the state of the art.

[01 1] The figures listed below, ranging from 2 to 12, refer to the invention in question: Figure 2 - shows box and lid with its components in exploded perspective. In details A and B, the UV-C LED plates on the lid and the printed circuit board were turned upside down (in a movement indicated by an arrow), in order to show their two sides;

Figure 3 - shows, in sequence, the lid receiving its components;

Figure 4 - shows, in sequence, the box receiving its components;

Figure 5 - shows box and lid assembled with its components, connected to the dedicated printed circuit board. In this view, the lid is supported on the upper edge of the rear wall of the box;

Figure 6 - shows the lined liner to cover the box with its lid. As can be seen, the coating has predefined cutouts to fit the electronic components that must be kept exposed. Furthermore, the coating has, on its internal surface, a reflective material applied;

Figure 7 - shows box and lid forming structured “souls” after applying the coating, forming the cabinet with some of its components strategically exposed. On the side, detail A showing one of the predefined cutouts of the covering;

Figure 8 - shows in sequence the transparent lens made with polymeric material with high UVC transmittance, aligned and then positioned by its apexes on corners inside and at an intermediate height of the cabinet. On the side, detail A showing one of the vertices of the supported transparent lens; Figure 9 - shows the closed cabinet, ready for use;

Figure 10 - shows that the cabinet was opened to introduce the instrument to be sterilized, supported by the transparent lens;

Figure 1 1 - shows the instrument receiving radiation incidence both superiorly, from the lid, and inferiorly, from the bottom of the cabinet. In detail A, it is shown that radiation can also be caused from the sides of the cabinet.

Figure 12 - shows that, when opened for use, the emission of radiation by the UV-C LEDs is automatically interrupted, for safety.

Figure 13 - shows the possibility of hanging objects inside the cabinet, using a metal rod.

[012] In accordance with the attached figures, the “SET FOR ASSEMBLY AND STRUCTURING PORTABLE CABINET, WITH ELECTRO-ELECTRONIC ARRANGEMENT FOR DISINFECTION AND STERILIZATION SYSTEM OF HOSPITAL AND SIMILAR MEDICAL INSTRUMENTS”, object of this Invention Addition Certificate, constitutes , as shown in particular in figure 2, from a box (1) and its lid (2), preferably injected into semi-rigid plastic material.

[013] The box is (1) open on its upper edge (la), closed by side walls (1b), front wall (1c) with internal recess (ld) along its upper edge, in addition to a rear wall (le) , all supported by the bottom (If). From the internal vertices extend, from the bottom (lf), angles (lg) that extend to the intermediate height of the box (1), where, after spacing, the respective sideboards (lh) are aligned. The lid (2) is equipped with side flaps (2a) and front flap (2b) with a central recess (2c), closed by the side upper part (2d) being, however, open in its rear part (2e). Cap

(2) is also hollowed out on its upper face (2d), by a rectangular cutout (2f) next to the back (2e) and, next to the front flap (2b) hollowed out by two more circular cutouts (2g) and ( 2h) of different diameters, with larger and smaller cuts respectively.

[014] Box (1) and lid (2) are assembled separately. As shown in figure 3, the cover (2) receives through the recess (2f) a USB connector (3), through the cutout (2g) an on/off button (4), through the cutout (2h) an LED indicator (5) , receiving, on the inner surface of its face (2d) a UV-C LED board (6) and a printed circuit board (7) and, also, in the recess (2c) an electromagnetic sensor (8). As shown in figure 4, the box (1) receives, at the bottom (lf), a UV-C LED board (9) and, in the internal recess (ld), a metal base (10).

[015] Figure 5 shows the electronic connection through which the printed circuit board (7) receives wiring from the USB connector

(3), the on/off button (4), the signaling LED (5), the UV-C LED boards (6) and (9), in addition to the wiring for the electromagnetic sensor (8).

[016] As shown in figure 6, the lid (2), with its open back part (2e), is positioned on the upper edge of the rear wall (le) of the box (1) so that both receive a coating (11) of fabric or polymeric film with predefined holes according to the components already assembled, exposing the UV-C LED boards (6) and (9), the USB connector (3), the on/off button (4) and the signaling LED (5 ), in addition to the angles ( lg) and their sideboards ( lh). When the coating ( 1 1 ) is applied, the box ( 1 ) and lid (2) become “souls” of the structuring of a semi-rigid cabinet ( 12), thus assembled, as shown in figure 7. The coating ( 1 1 ) , in addition to structuring, it allows the lid articulation (1) by its rear part (2e), which couples its side (2a) and front (2b) flaps to the box (1), closing it hermetically. In enlarged detail A of figure 7 you can see enlarged, for example, the predefined cutout in the covering (11) through which the sideboard (lh) is exposed. The coating (11) has an internal surface with reflective material applied to it.

[017] Then, as shown in figure 8, in the gap formed between the angles (l g) and their sideboards (lh) a transparent lens (13) is fitted, “tightly”, by its vertices, shown in detail A. at the intermediate height of the cabinet (12), between the UV-C LED boards (6) and (9).

[018] For use, as shown in figure 10, via the USB cable (3) the cabinet (12) is energized and the instrument (IN) to be used by the professional is seated on the transparent lens made with high UVC transmittance polymeric material ( 13) or hanging from the metal rod ( 14). The instrument (IN) is placed in an envelope (E) that allows UVC rays to pass through and which, using its own indication method, signals that its contents have undergone disinfection. When the on/off button (4) is activated, the UV-C LEDs on the plates (6) and (9) begin to emit both from the inner surface of the upper face (2d) of the lid (2) and from the bottom ( lf) of the box ( 1 ) and, due to the fact that the instrument (IN) is “suspended” supported on the transparent lens made with polymeric material with high UVC transmittance, ( 13), or hanging inside the cabinet ( 14) at an intermediate height of the cabinet ( 12), the incidence of UV-C radiation occurs from top to bottom and bottom to top, reaching the surfaces to be sanitized without “shadows”, as shown in figure 1 1. The incidence of radiation is boosted by the material reflective applied internally to the coating ( 1 1 ). [019] Each cleaning cycle, timed under control by the dedicated printed circuit board (7), occurs only after pressing the on/off button (4) and with the lid (2) closed, this action being indicated by the lighting of the LED flag (5). When the cabinet (12) is opened, the electromagnetic sensor (8) on the lid (2) moves away from the metal base (10) of the box (1) and a signal is sent to the printed circuit board (7) which turns off the LEDs. S UV-C (6) and (9) so that the radiation does not reach the professional, as shown in figure 12.

[020] Easy to install, the cabinet can be connected to a 5V voltage via the USB (3) type-C connector or have a power supply integrated into the product, according to the project's needs, and can be connected to a voltage of 127 or 220Vac.
