Abstract

The invention relates to a decontaminating access door that provides means for taking, viewing, and analysing a thermographic image of a person who wants to access a room and who can be recognised by means of facial recognition techniques, and for decontaminating the person on the threshold of the door to access the room where it is installed. In addition, after entering the room, clothes and footwear can be placed in a compartment located in the same door in order to be sterilised. The door is also provided with a disinfectant dosing device. In some embodiments, at least one UVc radiation source is embedded in the frame. The door is intended for the industrial sector that manufactures decontamination equipment for use in healthcare, home, and industrial environments.

Description

DECONTAMINATING ACCESS DOOR

Technical sector

Intended for the industrial sector that manufactures decontamination equipment, for application in sanitary, domestic and industrial environments.

Background

Different innovations aimed at providing means of decontamination and asepsis are known, both those aimed at providing necessary solutions in an industrial environment, derived from various catastrophes or those generated by health crises such as that caused by Covid-19, in this way, for example, The use of sprinklers with a chemical disinfection agent is set out in patent document WO 2017/203077 A1 of the applicant Alonso Holgado that describes a cylindrical body provided with a central hole in its cover to remove the head through it and not expose it to the spray of a disinfectant agent, other means of spraying are focused on specific applications such as the automated disinfection of a toilet room as set out in the Spanish utility model with publication number 1025788 of the owner Atena SA Others focus their contribution on their modularity or on being easily removable, as can be seen in document ES 1076364U of the applicant Hidrotec Tecnología del Agua S.L. which describes a cabin for the decontamination of people through a shower with a simple structure. On the other hand, there is literature that describes disinfection booths to be installed mainly in places with large capacity and public attendance, which use sprinklers.

Therefore, there are no known inventions that advantageously solve the technical problem such as the invention advocated. Object

Provide decontamination means that in an integrated way provide a technical solution to the asepsis needs when we enter a room, of special relevance at the access doors of homes, communities or buildings for public and industrial use.

Description

The decontaminating access door that is the object of this report offers means both to make, view and analyze a thermographic image to the person who wants to access the room, being able to be recognized by means of facial recognition techniques by having a video camera as a peephole located on the outside of the door, as well as to decontaminate it on the same threshold as the access door to the room where it is installed.

On the other hand, after entering the room, it allows you to deposit clothes and footwear in a compartment located in the same door or leave small daily items such as wallet, keys, sunglasses or a mobile phone, for example, to be disinfected in another smaller compartment It also includes a disinfectant dispenser that can be used for the hands or to apply to any surface. This makes it possible to isolate this clothing and belongings from the rest of the home, office or workplace, returning them safely when a process of inerting possible pathogens has been applied. For this, it comprises a plurality of sprinklers located on the face of the frame in contact with the edge of the door, surpassing the plane of the latter and on the outer side of the room, the sprinkling is possible by comprising a pump and a reservoir to arrange the agent to be sprayed contained in the door, comprises on the outside of a thermographic camera. On the inside of the door and forming part of it, it has several compartments, a decontamination compartment equipped with a door intended to deposit the clothes and / or footwear to be decontaminated, possible by presenting at least one source of ultraviolet radiation in its spectrum germicide (UVc) that has shelves permeable to this radiation; It has a second, smaller compartment for the disinfection of small objects such as a wallet, sunglasses, keys, etc ... which identically comprises at least one UVc source. Versions have been planned in which the decontamination of these compartments is carried out by means of ozone, for which it comprises at least one ozone generator arranged in the door, or others, in which the disinfection is carried out with the combination of these two methods. . It has conventional means to prevent disinfection if the door of a compartment is not closed, of a control unit that manages the functions of the access decontamination door. Again on the inside of the door there is a data input and output element with a touch screen display and an auxiliary control button from which the basic functions are activated, as well as a dispenser for a disinfectant liquid. to the hands or to treat a surface. It has a camera on the outside of the door to see who wants to access the room, as well as using the appropriate software to identify them. Versions have been envisaged in which the frame has at least one source of UVc radiation embedded in it.

Brief description of the drawings

For a better understanding of what is described in the present specification, some drawings are attached in which, by way of example, a list of the figures of the proposed invention is represented.

Figure 1 shows the access decontamination door showing its interior face, the referenced elements are: 1 frame, 2 door, 3 decontamination compartment, 3 'decontamination compartment for small objects, 4 and 4' upper and lower compartments respectively to house the components of the system, 5 data input and output control device with display, 6 operating button, 7 disinfectant dispenser, 8 ozone generator, 9 spray pump and 10 spray agent tank. Germicidal UV Emitters 11 and Germicidal UV Emission Permeable Supports 12 are also shown.

Figure 2 shows a top view in which the frame 1 of the door can be seen in which the sprinklers 13 are embedded, the decontamination compartment 3 and the thermographic camera 14 located on the side of access to the room and 15 a conventional video camera ..

Figure 3 shows an embodiment in which the decontamination compartment (3) protrudes from the profile of the door.

The profiles that make up the frame 1 are represented in the view of figure 4, in this case the sprinklers 13 and the germicidal ultraviolet emitters (11) can be seen. Preferred embodiment

A preferred embodiment is cited by way of example, the materials used in its manufacture, as well as the application methods and all the accessory details that may be presented, as long as they do not affect its essentiality, being independent of the object of the invention. This preferred embodiment reflects the embodiment and embodiment of the invention specifying details that help to understand it.

The decontamination access door is based on the characteristics set forth in this specification, it is described using UVc decontamination in its compartments and the use of sprinklers in the frame, in this way it presents a plurality of sprinklers arranged on the face of the frame in contact with the edge of the door and in a plane distanced from it towards the outside (13) figure 2, for this it comprises a pump (9) and a tank (10) containing the agent to be sprayed located on the door in an accessible compartment (4 ') intended for this purpose, figure 1.
