Description

DESCRIPTION

Respirator device for protection against viruses and bacteria

TECHNIQUE SECTOR

The present invention refers to a respirator device for protection against viruses and bacteria whose obvious purpose is to provide a completely safe means that protects against viruses and bacteria when operating in environments susceptible to contagion.

Although the invention is applicable in multiple fields, it is preferably focused on those fields in which the degree of security must be maximum, such as health, laboratories, research, etc.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, a multitude of masks are known for filtering the air inhaled and exhaled by the user, which, although they offer a certain degree of protection, are not completely safe, since they do not adapt in a completely sealed way. to the physiognomy of the user.

In addition, this type of mask prevents the visualization of part of the characteristic features of the face of its users, which makes it difficult to identify them.

EXPLANATION OF THE INVENTION

The recommended respirator device for protection against viruses and bacteria satisfactorily resolves the aforementioned problem, based on a simple but highly effective solution.

For this, and more specifically, the device of the invention is embodied in an airtight body, made of acrylic materials, such as polycarbonate (hereinafter PC), polymethylmethacrylate (hereinafter PMMA), polypropylene (hereinafter forward PP), etc, with an irregular truncated cone shape, transparent, to facilitate the identification of its user, as well as the visual reading of lip movements, expressions and other gestures, body that is finished later in a PMMA oval that forms two tabs, an interior one to house a flexible membrane that adapts to the user's physiognomy, and an exterior one to house the mouth of the PPE (individual protective equipment) garment hood.

The aforementioned main body is finished off above in a cylindrical tubular element, also made of colorless PMMA, whose ends are threaded for the coupling of respective threaded rings with interposition of respective PP fabric filters, including an internal structure based on radial arms that support a electronic microfan arranged centrally, so as to define two concentric cylindrical chambers, the outer one intended for inhalation, while the central or inner one is intended to cause a forced expulsion flow of exhaled air.

The micro-fan will include a power supply port, the device being supplied with the corresponding cable-charger set.

In this way, it is possible to obtain a highly effective and safe respiratory protection device against viruses and bacteria, ideal for working in potentially dangerous environments.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of its practical embodiment, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 1.- Shows a front perspective view of a respirator device for protection against viruses and bacteria made according to the object of the present invention.

Figure 2.- Shows a rear perspective view of the device of the previous figure.

Figure 3.- Finally, it shows a detail in lateral perspective of the device of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the respirator device for protection against viruses and bacteria is made up of a main body (1) in the shape of an irregular truncated cone, which in the chosen practical embodiment has a thickness of order of 0.5 mm, obtained in transparent and impermeable material, such as PC, PMMA, PP, etc., in the shape of an irregular, truncated, transparent cone and which is subsequently finished in a pair of tabs (2-2'), the elastic interior, adapting to the physiognomy of the user's face, and the second tab defines a groove to facilitate the stabilization of the elastic mouth of the PPE garments and thus form an autonomous team.

As can be seen in figure 3, the main body (1) is finished above in a cylindrical tubular element (3), also transparent, which presents its threaded ends (4), in which the respective rings are intended to be implanted. (5) with complementary threads and carriers of the complementary filters (6) made of PP cloth.

Returning to figure 1, it can be seen how the cylindrical tubular element (3) includes an internal structure based on radial arms (7) that end in a second cylindrical tubular body (8) of smaller diameter in which it is integrated. tightly a micro-fan (9), so that these cylindrical tubular bodies (3-8) define two concentric chambers for the circulation of inhaled and exhaled air flows, respectively, the external chamber (10) being intended for the entry of inhaled air , air that will be properly filtered by the filters (6), while the micro-fan (9) is responsible for expelling the air exhaled by the user, also filtered.

As an example, this fan could have dimensions of the order of 40X40 mm and 20 mm deep, with a power of 1.10W, being powered by an external rechargeable 5V DC-1000mA battery, with a port (11) watertight, for your power supply with the corresponding cable assembly.

The device thus described could have an autonomy at full charge of 9 hours, although it could integrate other models of electronic components to vary said autonomy depending on the specific needs of each case without affecting the essence of the invention.
