PRIOR ART DESCRIPTION

Today, various infectious diseases remain enemies of human survival and development; there are a large number of pathogenic microorganisms in the environment in which we live, they usually exist in the form of bacteria or viruses, parasites, fungi and other pathogens.

These pathogenic microorganisms can be transmitted to humans through various channels and endanger human health. Once these pathogens infect humans, some of them have a major impact on the health of the population.

In fact, the new coronavirus that emerged in 2019 has devastated the world and life has become more vulnerable to this virus. Currently, millions of people have been infected with this new virus around the world, and the death toll is still unpredictable.

At the same time, the world economy has also suffered an unprecedented shock, microbial contamination is a global concern in many industries, especially the health industry.

As has been seen, the impact caused by the pandemic is enormous, and has revealed the difficulties that countries face, both in managing the immense number of patients already infected, and in implementing measures to stop the spread of the virus. virus. Overall, it costs countries billions of dollars in expenses per year. Contaminating pathogens plague private and public settings; many communicable diseases are transmitted through contact with contaminated areas, for example, viral and bacterial diseases can be transmitted through physical contact with surfaces on which infectious agents reside.

The contagion power of many viruses, especially that of the new Coronavirus, is one of the relevant edges to face as a containment strategy, with physical protection measures being the first measures to be adopted, among others, are mechanical barriers given by the use of masks, facial shields and gloves. But none of these measures is effective if there is no continuous replacement of gloves and masks, or disinfection of face shields that allow their reuse.

One of the great difficulties has been seen in the hospital environment, where the exposure of health personnel is evident, together with the feasibility of being a vector of contagion between one patient and another.

For this reason, health personnel are obliged to constantly replace the equipment used, reaching thousands of items that are consumed daily by each hospital care facility worldwide.

Repeating this situation in each venue, many of the personal protection products have been out of stock at a general level. But another relevant factor to consider is the environmental impact caused by the unfortunately necessary increase in the use of disposable items; especially because several of these implements are made with low-cost materials, such as polymers that are not degradable or reusable, such as latex gloves or many types of masks.

Despite the above, it is known that many of the personal protection products can be reused after a safe sanitization or sterilization process, such as the case of goggles, face shields, some types of masks or protective masks, and also various items of protective clothing, especially made of textile materials. As the sanitization of protective suits is already known, for example, of the type used in laboratories where biological research with bacteria or viruses is carried out; or in the usual sanitization of hospital equipment or surgical instruments.

Within the different technologies developed and known to carry out processes of sterilization or sanitization of materials of different kinds, is the use of irradiation Ultraviolet, it features high broad-spectrum efficiency and has the ability to kill most bacteria and viruses.

The principle of this type of sterilization is to use the appropriate wavelength of ultraviolet light to destroy the molecular bonds of pathogens.

Ultraviolet (UV) light is classified into three wavelength ranges: UV-C, from about 200 nanometers (nm) to about 280 nm; UV-B, from about 280nm to about 315nm; and UV-A, from about 315nm to about 400nm. As a general rule, the shorter the wavelength, the more power the wave has.

Ultraviolet light, and in particular light in the UV-C range, is capable of deactivating the DNA of bacteria, viruses and other pathogens, thereby destroying their ability to multiply and cause disease. This effectively results in the sterilization of microorganisms.

The antimicrobial properties of UV-C light (ultraviolet light - C band) are known and have been widely used to kill germs containing DNA and RNA (genetic material), including disease-causing bacteria, viruses, fungi and mold.

Ultraviolet light with a wavelength between about 250 and about 280 nm provides the greatest germicidal efficacy.

In the state of the art, long-standing developments are known where the use of ultraviolet irradiation as a germicidal agent is described; In most of them, the aim is to increase the irradiance of the UV source with respect to the element being treated, with the application of reflective surfaces. An example of this is seen in patent US7875247, published on 01/25/2011, which refers to a "UV flow multiplication system", where means of sterilizing air flows, such as air conditioning, are described. through very high levels of irradiance.

While such levels of microorganism reduction cannot be achieved on surfaces due to surface imperfections, which can prevent exposure of organisms to UV light, with appropriate exposure settings and appropriate UV dose, Significant reductions in microbial contamination can be achieved by generating a sterilizing effect. Other applications are seen in box-type UV sterilizers, known for their use in the sterilization of all kinds of objects, such as contact lenses, safety glasses or surgical instruments.

In many of these sterilizing devices, a single irradiation source and/or fixed source located in a confined space with walls of reflective material is used, as can be seen in the content of document CN110665029A, published on 01/10/2020, which describes an "Ultraviolet disinfection cabinet for instruments for medical use", where the source is located at a single upper point that irradiates the objects to be sterilized.

One of the disadvantages of this type of device is that often, in an object to be sterilized, there are areas that are shaded from the UV irradiation produced by the sole source. Furthermore, the object to be sterilized is required to rest on a support during the sterilization process. When the support is not transparent to UV irradiation, the support also contributes to shading the object.

Another disadvantage that derives from devices with a single irradiation source is that they do not allow the processing of several articles at the same time.

Other improved solutions are known, where two opposite sources are arranged that irradiate articles on both sides, normally they are arranged on grid-type trays or made of a material that is transparent to this type of irradiation, as exemplified in document US2017202988A1, published on 20/ 07/2017, which describes a "Microbial Sanitization Chamber".

Although these solutions improve, insofar as they irradiate a larger surface of the object when facing it from both sides, they still do not allow processing several articles at the same time and do not ensure the elimination of shadow areas where the irradiation does not reach with the same intensity, or simply, does not reach.

Solutions such as the above are inefficient, high cost in relation to the low number of objects that are capable of processing effectively in a given time, so they would be inadequate in contexts of high demand.

Sterilizing devices are also known that, in addition to operating with UV-C light irradiation, include the application of ozone that enhances the sanitizing effect.

An example of this can be seen in the content of patent document US2010266445, published on 10/21/2010, which shows an "antimicrobial sterilizer ultraviolet"; It comprises a box-type device, several UV-C tubes facing a quartz tray, transparent to irradiation, and an ozone generator.

Although this solution improves the sterilization result by incorporating ozone and a transparent tray to irradiation, it maintains the disadvantage of not being able to process several articles at the same time, since it comprises a single tray.

Evolutions of the previous solution, seek to overcome the problem of the number of objects to be processed, simply by increasing the number of trays; An example of this is represented in the content of patent document CN110973229A, published on 04/10/2020, which describes a "Device for preserving fruits and vegetables"; it shows a container, refrigerator type, with several interior trays provided with perforations for the passage of an ozone flow; each of the trays includes a pair of UV-C tubes on its underside, while the trays have side sliders to facilitate access to them.

Although in this case the increase of more space to hold and process a greater number of objects is evident, thanks to the provision of a greater number of trays and to the fact that each one has UV-C tubes under them, in any case the objects receive irradiation from a very irregular manner over its entire surface, since when placing the tubes under the trays, they radiate directly only to the surface of the objects arranged in the lower adjacent tray, since it does not describe that the material of the trays is transparent to irradiation , only indicates that they have perforations for the permeability of gas flows, so that the lower surface of the object receives less irradiance, and if what is sought is that all objects receive the same dose on their entire surface, then the process requires longer exposure time to ensure the desired sanitization.

In the previous case, even if the trays were transparent to UV-C irradiation, the fixed position of the tubes implies that there will always be points of projected shadow where the objects do not receive irradiation, either caused by the tray itself or by objects adjacent to each other. Additionally, the fixed position of the tubes also implies that the points furthest from the objects with respect to the focus will require a longer exposure time to achieve the same irradiation dose as that received at those points closer to the source.

Other solutions are also known that seek to overcome the problem of exposing the surface of the objects to the source and the number of objects that can be processed, incorporating a rotation mechanism in the means for holding the articles, as shown. exemplified in document CN211356913, published on 08/28/2020, referring to a "Sterilizing device for medical protective clothing". This document describes an apparatus with a rotating platform that supports pillars to hang garments at its upper end, the UV-C tubes are arranged at the top of the hanging garments, located on the interior vertical faces of the container, facing said garments from their sides.

In this case, although the garments are irradiated in their entire height and, by turning the platform, the exposure of each garment to the source is optimized; Its main disadvantage is that the garments, when hanging and rotating the platform, determine that the surfaces to be treated are in a changing, unpredictable position, generating folds that prevent their entire surface from receiving regular irradiation.

These last two solutions, although they allow the processing of more garments or objects at the same time, have the disadvantage that the same objects generate shadow points between each other and there will always be points further away from the source, so they require more time. of exposure in order to ensure that all its parts obtain the minimum necessary dose of sterilization, especially in the areas of dead spots where shade is produced.

This can be even more complex if we are dealing with three-dimensional objects where their length, width and depth are similar to each other, causing that face of the object that is oriented parallel to the direction of irradiation, receives low doses, or no doses in the points furthest from the source.

Another relevant aspect to consider in order to have an effective sanitization system is the safety aspect of its operation; especially in the sense of ensuring that the people who handle the devices are not exposed to the source of UV-C irradiation or to high levels of ozone.

As mentioned above, in the prior art there are several solutions that, in addition to operating with UV-C irradiation sources, incorporate ozone flows, applied especially to sanitize and deodorize garments or any treated object.

While ozone is known to have sterilizing and deodorizing properties, too much ozone is known to be harmful, polluting the air, and endangering human health. Due to the above, there are several solutions that use ozone for their sanitization processes that incorporate a means of eliminating ozone before the user accesses the sterilized objects or garments. Conventional systems employ layers of activated carbon and/or catalysts provided in the waste air passage, as exemplified in the patent CN207220511, published on 04/13/2018, which deals with a “Disinfection cabinet for a microbiological experimentation room”.

The problem with the use of ozone catalysts is that they are inputs that must be replaced every certain cycles of use, which implies an additional expense in the ideal functioning of the system.

Given all the situations just reviewed, it follows that there is a need for improved, optimized sterilization systems, devices and/or methods that allow the treatment of a greater volume of objects at the same time and in less time, ensuring a better result. optimal and efficient, allowing its application in high-demand environments where frequent rotation or replacement of personal protection items or other items is necessary, through which the spread of pathogenic agents may occur; and where these systems are comprehensive, not only ensuring the germicidal effect on the treated objects, but also taking charge of a safe purification of the residual flows of each cycle.

DESCRIPTION OF THE INVENTION

The present invention is related to a device for sterilizing objects using UV-C light irradiation and an ozone flow that, in addition to helping to sanitize, allows the elimination of non-volatile odors, where the device is capable of optimizing the sterilization process by reduce the necessary time of exposure to irradiation of several objects at the same time and ensure that the entire surface of the objects receives a minimum necessary dose of sterilization within the reduced period of time; and provide residual air purification at the end of each operating cycle,

One of the main objectives of the present invention is to provide an object sterilizing device that allows UV-C light irradiation to be applied for a reduced period, ensuring that the integral surface of the treated objects receives, at least, a minimum necessary dose of irradiation to ensure its sterilization of 20 mJ/cm2.

Another of the main objectives of the present invention is to provide an object sterilizing apparatus that allows the simultaneous processing of several objects at the same time during the same operating cycle.

Another main objective of the present invention is to provide an object sterilizing device that allows a sterilization process to be carried out safely, on the one hand, eliminating the possibility of a user being exposed to radiation or to a harmful ozone level; and on the other hand, reducing the chances of mishandling that can damage the user due to the breakage of any input content dangerous to their health; which additionally helps to extend the useful life of the supplies.

An additional objective of the invention is to provide an object sterilizing apparatus that facilitates the disposition of the objects inside it.

Still another objective of the invention is to provide an object sterilizing device that allows different embodiments, where at least one of them is of low implementation cost, so that the largest number of hospitals or other facilities not necessarily medical, can implement one or several devices that allow facing a high demand for sterilization means, as happens during pandemic scenarios.

Yet another objective of the present invention is to provide an object sterilizing apparatus that allows efficient processing of several objects at the same time, regardless of their shape, so that all of them receive the target dose of irradiation on their entire surface.

An additional objective of the present invention is to provide an object sterilizing device that can be easily operated by a user, without the need for training or expertise in this technology.

Specifically, the specific technical problem is related to being able to sterilize several objects at the same time, in a short time, but without increasing the amount of ultraviolet light sources, since this input is the most expensive to carry out the sterilization procedure.

It is important to know that the killing of microorganisms by UV light depends on the total UV energy applied (also known as "UV dose"). Ea UV energy is the product of the incident UV power (also known as "UV irradiance") and the exposure time.

UV energy can be measured, for example, in joules per square centimeter (J/cm2), and power or irradiance can be measured in units of watts per square centimeter (W/cm2). Although the susceptibility to ultraviolet light varies in different pathogens, recent studies have shown that it is necessary to reach a minimum dose of 20 mJ/cm2 (20 millijoules per square centimeter) to inactivate the SARS-CoV-2 virus.

The irradiance of ultraviolet light has an exponential attenuation law due to its propagation in air and water, which leads to a significant decrease in its power the greater the distance to the object, and the efficiency of sterilization and disinfection increases. significantly reduces. In other words, if the distance at which the dose is applied is doubled, the irradiance of UVC light decreases not by half, but by four times. In the same way, if the irradiation distance is halved, the irradiation power increases not twice but four times; reducing by four times the time needed to reach an inactivation energy dose.

Therefore, for the present invention, the factor of the distance that each part of the object has to the source is an important factor of the proposal; knowing that, according to the size of a support where the objects are placed, and assuming the type of objects to be treated, there will be a maximum surface to be irradiated that needs to receive an optimal dose of 20 mJ/cm2.

To ensure an optimal result, it should be considered that most of the objects that may possibly be treated with the present invention have an irregular surface; they are not flat, but objects with curved surfaces predominate, such as goggles, face shields or some types of face masks that even have pleated areas.

If it is known that by halving the distance to the source, the irradiation power increases four times, and this translates into a four-fold reduction in the time needed to achieve a sterilization energy dose; Therefore, the present invention seeks to optimize the sterilization process, since, instead of increasing the number of foci to treat several objects simultaneously and/or increasing the time of exposure to irradiation, it proposes means that adequately mobilize and position the irradiation source with respect to the objective, where said source comprises a minimum number of sources emitting UV-C light, so that all points, on all faces, of several objects irradiated simultaneously, receive at least a minimum dose of sterilizing irradiation during a cycle of minimum duration.

The present invention specifically proposes a sterilizing device for objects through the application of UV-C light irradiation and, in addition, the application of an ozone flow, which allows sanitizing parts of objects that have folds or overlapping layers that receive less UV-C irradiation, such as occurs in some clothing.

The apparatus is capable of optimizing the sterilization process by reducing the time of exposure to irradiation of several objects at the same time, but ensuring that the entire surface of the objects receives a minimum necessary dose of sterilization within the reduced period of time; and additionally, provide residual air purification at the end of each operating cycle to prevent high levels of ozone from remaining inside the device. The apparatus comprises a multiple source of sterilizing irradiation with UV-C light; a static component with supports to arrange the objects to be treated; a mobile component that carries said multiple irradiation source and describes a linear path; an ozone flow generator; residual air purifying means; a security cabinet containing the components of the device and an electronic control component of the device that allows it to operate automatically.

The multiple source of sterilizing irradiation has at least two UV-C light emitting tubes, where a first UV-C light emitting tube is arranged, parallel and distanced, with respect to a second UV-C light emitting tube, to irradiate the objects that are arranged on the supports of the static component, located between both light sources.

Each of the supports on which the objects are arranged are transparent to UV-C irradiation and permeable to ozone flows; they have at least one first face and one second face, opposite each other and irradiable directly and simultaneously by said UV-C light-emitting tubes; specifically, said first face of the support is directly irradiated by said first UV-C light emitting tube, and said second face of the support, opposite to the first face, is directly irradiated by the second UV-C light emitting tube. c.

Then, the number of supports is at least one, while the number of UV-C light emitting tubes is in a numerical relationship with respect to the supports, where for each one of the irradiable faces of the support, there is at least one UV-C irradiation emitting tube.

In order for the device to be able to ensure that the entire surface of the objects receives the minimum dose of sterilizing radiation, the UV-C light-emitting tubes are carried in a mobile component that moves linearly and bidirectionally, in relation to the static component; where said UV-C light emitting tubes are simultaneously movable, at least, in the direction of a transverse axis or a longitudinal axis of the supports.

Specifically, for each support where the objects are arranged, a first UV-C light emitting tube is arranged parallel and spaced with respect to the first irradiable face of the support, according to a first constant distance; and said second UV-C light emitting tube is arranged parallel and spaced with respect to the second irradiable face of the support, according to a second constant distance.

In a preferred embodiment of the invention, said first distance of a first UV-C light-emitting tube with respect to the first irradiable face of the support element is greater than the second distance of a second UV-C light-emitting tube with respect to of the second irradiable side of the same support element. The foregoing, substantially because the invention seeks an equitable average in the reception of irradiance on both sides.

This distance can be adapted according to the type of objects to be treated, mainly depending on their size, and for any of the possible applications, the speed of movement of the light source can be recalculated to achieve the minimum dose.

In a preferred embodiment of the invention, the object supports are positioned horizontally in the static component, like trays; constituting, its first irradiable face, as an upper support surface where the objects to be sterilized are placed; while its second opposite irradiable face is constituted as the lower surface of the support.

In another embodiment of the invention, the supports of the objects are positioned vertically in the static component, constituting its first irradiable face as a first lateral surface, while its second opposite irradiable face is constituted as a second lateral surface. ; said supports being formed as hanging elements from which objects hang in a hanging manner.

In yet another embodiment of the invention, the object supports are positioned vertically in the static component, as a frame-shaped panel; constituting its first irradiable face as a first lateral surface, while its second opposite irradiable face is constituted as a second lateral surface; where the frame-shaped panels comprise hook elements that allow various objects to be hung.

In the case of the preferred embodiment of the invention, where the supports of the objects are positioned horizontally, it should be noted that the objects placed on their upper irradiable face will receive direct incident irradiation on their upper and lateral surfaces, coming from the UV-C tube parallel to said upper face, and which, by the way, is distanced from said upper face according to the aforementioned first distance; On the other hand, the lower surface of the objects will not receive incident, direct irradiation from the second UV-C tube parallel to the second support face and which is distanced according to the second distance, since said irradiation is interfered by the body of the object itself. support.

In order to provide a similar irradiation dose on the entire surface of the objects, in the case just described where the supports are arranged horizontally, said second distance, presented by the second UV-C tube with respect to the second surface of the support, is less than the distance presented by the first UV-C tube radiating from the first surface of the support, so as to compensate for the radiation interfered by the support, even though said support is made of a transparent material to UV-C radiation; as well as to compensate for the asymmetry in the shape of the objects to be sterilized.

At the same time, it should be noted that this difference in the distances between the UV-C tubes and the corresponding surfaces of the supports, allows generating a larger space on the upper surface to arrange objects of various sizes.

On the other hand, in the alternative embodiments of the device, where the supports are arranged vertically so that the objects are hung, it should be noted that the objects are exposed to direct irradiation by their corresponding first and second UV-C tubes, so that, in these cases, the distance between the first UV-C tube with respect to the first irradiable face of the support is equal to the distance between the second UV-C tube with respect to the second irradiable face of the same support.

In the supports of the objects, a perimeter contour is defined between both first and second irradiable faces, which, in an embodiment of the invention, said supports can be quadrangular or rectangular in shape, the perimeter contour is formed by a front edge, opposite to a rear edge, between which lateral edges extend, also opposite each other.

In an embodiment of the invention, said front edge and said rear edge of the support are parallel to the longitudinal axis of the support. While, in another embodiment, said front edge and said rear edge are parallel to the transverse axis of the support.

It will be understood that the support can be of any other suitable form, which facilitates the distribution of various objects, which facilitates their production and, at the same time, facilitates the assembly of the support in the apparatus.

In a preferred embodiment of the invention, the support comprises a rigid perimeter frame that supports and tensions a woven structure, forming a regular open grid, based on filamentary elements of transparent material to UV-C irradiation, where the open grid generates multiple openings that allow permeability to an ozone flow and ensure transparency to irradiation. The material transparent to UV-C irradiation of the woven filamentary elements, which make up the grid, is preferably a polymeric material, such as a polyamide compound. In another embodiment of the invention, the object support comprises a rigid perimeter frame that supports a multi-perforated laminar structure to provide permeability to an ozone flow, where this laminar structure is made of a transparent material to UV-C irradiation to allow the lower surface of the treated object, receives sufficient irradiation to complete a minimum dose necessary for its sterilization.

In yet another embodiment of the invention, the object support comprises a rigid perimeter frame that supports multiple rigid linear elements forming a support grid, where the elements are spaced apart from each other forming spaces to provide permeability to an ozone flow, and They are made of a material transparent to UV-C irradiation to allow the lower surface of the treated object to receive sufficient irradiation to complete a minimum dose necessary for its sterilization.

In these latter cases, the material transparent to UV-C irradiation can be selected from quartz, glass or an alloy of glass and quartz.

Said static component that forms part of the apparatus and that is mainly the one that contains the supports of the objects, is formed by at least two structural frames, spaced apart, each one formed by at least two parallel vertical straight profiles, based on which are mounted straight guides for the movement of the mobile component, and some sliders in which the supports of the objects are mounted.

In the preferred embodiment, where the supports for the objects go horizontally in the apparatus, the sliders are mounted horizontally on both structural frames, so as to allow the supports to move towards the edge of the apparatus, to facilitate the arrangement of the objects to sterilize, thereby preventing the user from having to insert their hands to position the objects, running the risk of, on the one hand, placing the objects in an inappropriate position (mounted or very close to each other), and on the other hand, passing to carry the UV-C tubes and cause an accident. Also, the straight guides for moving the mobile component are arranged horizontally in the static component.

In the case of the embodiment of the invention where the supports are arranged vertically, the two structural frames are arranged horizontally, spaced apart from each other, one upper and one lower; each one formed by at least two parallel horizontal straight profiles, between which upper and lower straight guides are mounted, for the displacement of the mobile component; and in at least one of the structural frames, horizontal sliders are mounted that receive, in a sliding manner, said support elements of the objects that are arranged vertically; which can also be slid towards the edge of the device to position the objects. The mentioned mobile component that forms part of the apparatus of the present invention comprises a carrier frame in which the UV-C light-emitting tubes are mounted in a position parallel to each other; and at the same time, it comprises drive means that drive and allow the linear displacement of the mobile component, based on the static component.

The carrier frame is a rigid frame comprising at least two transverse profiles, parallel and spaced apart from each other; at least two longitudinal profiles, parallel and distanced from each other; mounting points for the UV-C light-emitting tubes arranged opposite each other on the carrier frame; where the carrier frame comprises an inner contour and an outer contour with four outer corners where bearings are mounted, which generate a sliding, stabilizing and anti-rotation effect of the frame during its displacement in the static component. These mounting points are provided with mechanical and electrical connectors to mount the UV-C tubes between them.

The driving means comprise motors with a transmission gear and straight and fixed toothed guides on the static body, oriented perpendicular to the longitudinal elements of the carrier frame.

In a preferred embodiment of the invention, such as the one where the object supports are arranged horizontally, the toothed guides that form part of the drive means are mounted parallel to the lateral edges of the support, so that the supporting frame moves from the leading edge to the trailing edge of the media, and vice versa; thereby allowing the UV-C tubes to be parallel to the longitudinal axis of the supports and to move along the smallest dimension of said supports, that is, to move in a direction of displacement in the direction of the transverse axis of the support.

The aforementioned security cabinet comprises double perimeter walls forming a hermetic internal chamber where the components are housed; It comprises a front face provided with a hinged hatch for access to the inner chamber, also with double walls, and compartments outside the inner chamber to accommodate peripheral components of the device. Said hinged gate is associated with a safety lock that prevents its opening during the operation of the apparatus.

The double walls surrounding the inner chamber comprise an inner radiation reflective panel to increase the incident radiation on the surface of the objects to be sterilized.

The residual air purifying means comprise a hot air generator which, thanks to the high temperature it generates, is capable of decomposing the ozone used to Sanitization and treatment of non-volatile odors. Where said ozone is provided through an ozone generator. It also includes an activated carbon filter associated with an air extractor that forces the evacuation of residual air.

The ozone generator and the hot air generator are preferably located in an upper area of the interior chamber, so that the flows go through the permeable supports thanks to the various openings or separations that they present, so that the ozone flow it can reach all objects arranged on all supports, upper and lower inside the apparatus; additionally, between each support and the inner panels of the double walls of the cabinet, a gap can be provided to allow side flows of circulation of ozone, hot air and exhaust flows to occur.

Meanwhile, the carbon filter and the air extractor are located, preferably, in a lower part of the interior chamber, to favor the exit and forced passage of the air with ozone that has been descending through the supports with the objects, forcing it to go through the activated carbon filter that eliminates odours.

The electronic control component comprises an operation interface by means of a control panel that is arranged in the cabinet, a power source, means of connection between the operable components and a processor to implement at least one preconfigured operation program to operate the components. in a synchronized manner and ensure the application of at least a minimum dose of radiated energy at all points on the items to be sterilized.

In operation, according to one embodiment of the invention, the carrier frame for the UV-C light-emitting tubes is oriented vertically, arranging the UV-C light-emitting tubes horizontally and parallel to the longitudinal axis of the support of the objects; where said carrier frame moves in a bidirectional linear manner based on the static component, following a direction of displacement along the transverse axis of the object support, and vice versa; allowing the UV-C light-emitting tubes, when moving, to irradiate the entire surface of the objects evenly. With this, the irradiation coverage that is obtained allows the most extreme points of the objects with respect to an initial position of the irradiation source, to receive the same dose as that received by the points closest to the source in the same position. initial.

It is important to consider that, as explained previously, the variation in the distance between the irradiation focus and the target surface generates significant changes in the total irradiance; even if the source were fixed with respect to the object, the irradiation coverage in the objective surface would not be regular towards each point of the objects, since the irradiance decreases exponentially towards those points of the object that are farthest from the focus.

In the irradiation process, an optimum irradiation point is produced where the greatest efficiency occurs, formed in the area or fringe of the object that has the least distance from the source, with an angle of incidence perpendicular to the target surface.

For the same reason, those faces of the object that are oriented almost parallel to the path of the light, receive a marginal or almost null irradiance; as well as in those areas of the objects where shadows are produced by the same adjacent objects.

Given this situation, the present invention provides the means to move said UV-C light-emitting tubes from end to end of the object support, following a linear path and at a determined speed in relation to the minimum and maximum distances of the object. source to the furthest points of the objects; so that, as the light source moves linearly, the high intensity irradiation target region changes, so that at some point in the path of the source, all points on the objects are a high intensity irradiation target region. High intensity; allowing those areas where shadows had initially been produced, to receive the same amount of irradiation as the rest of the areas.

Having a single tube for each face of the supports, it allows to treat various objects, of different shapes, ensuring that all the faces of the object, including the lateral ones that are located close to the periphery of the support, are exposed to irradiation to achieve the same dose. than that received on the other faces of the objects.

Likewise, by arranging the UV-C light-emitting tube that faces the underside of the support, at a distance less than the distance from the upper tube, it is ensured that the irradiance interfered by the support itself is compensated thanks to this lower distance; thereby achieving that the lower surface of the object placed on the support receives the same dose as the rest of the surface.

In particular, the present invention allows the effect of total coverage to occur simultaneously in several objects at the same time, optimizing the process and making it efficient, since it is proposed that the device comprises at least one support, while the Multiple source of UV-C light emitting tubes, as they are all mounted on a single carrier frame, allows all of them to describe the same movement at the same speed and at the same distance from the support they radiate. Intending to propose a device with simple operation, which does not require a complex instruction to be operated, it is desirable that the user be faced as little as possible with having to program the operation. Therefore, if each process or cycle considers a constant intensity of the source, a constant distance from the source to the supports of the objects and a determined size of said supports, then pre-fixed programs can be generated where the only thing that varies is the displacement speed of the mobile component that carries the UV-C light emitting tubes.

Assuming a homogeneous displacement of the equipment, in which the light source moves from one end to the other of the object support, sweeping type, under and over the elements to be sterilized, it will imply a reduction of approximately half the time compared to with the static systems known in the state of the art. In other words, 50% of the time will be saved or the dose will be doubled. All of the above, thanks to the non-static covering effect of the irradiance from a moving light source.

The more irradiation falls on more surface during a unit of time, the better result, since the dose is achieved in less time. It will be preferable for the tubes to be arranged along the larger side of the support and to move in the direction of the smaller side, since the round trip is less while covering the largest extension of the support with the objects; shorter length zippers are required. On the other hand, if the tubes were oriented parallel to the minor axis of the support, the total coverage is less than cm2 per second, there are points further away from the source, the length of the total displacement path is greater, it takes more time to go and return, maintaining the same speed; Requires longer zipper length.

The size of the supports can allow the arrangement of at least one larger object, while, preferably, the trays have a size that allows several objects to be placed spaced apart from each other.

The objects to be sanitized can be of various types and belong to different areas; However, by way of example only, without limiting the scope of the present invention, personal protection objects can be mentioned in a medical environment, made of textile material or another type of material, such as protective aprons, bibs, pants, shirts, etc. masks, face shields, goggles, filtering masks, etc.

They can also be objects for general medical or hospital use, such as medical instruments, sheets, towels, respiratory helmets, etc. Only, by way of example, may be mentioned objects such as goggles, helmets, non-disposable gloves and similar protective implements, of the type used in manufacturing or mining facilities.
