DESCRIPTION

Nasal filtering device for viruses, bacteria and other microorganisms

Technical sector

The present invention refers to a device that has been specially designed to act as a filtering medium for breathed air in order to prevent the aspiration of viruses, bacteria and other microorganisms.

The object of the invention is to provide a device that is implanted in the nasal cavities of the user, in such a way that, by controlling breathing, it allows the mouth to be free when eating or drinking in restaurants or any other place that is deemed convenient. totally safe way.

Thus, the filter of the invention is intended to replace or offer an alternative to the classical hygienic, sanitary masks, FPP2, N90, N95 and the like.

The invention is also of special application when it comes to communicating with deaf-mute people, a communication that until now was extremely complex when the face was partially covered with a mask.

Background of the invention

Currently, different types of masks are used as a filtering medium for viruses, bacteria and other microorganisms that, although they satisfactorily fulfill the function for which they were intended, have a filtering body that covers the nose and mouth, which prevents their use during the maneuvers of ingestion of food or drinks, and even makes it difficult to understand between people when they are talking, so it is common for said users to momentarily remove the mask for these operations with the consequent danger of being infected.

Furthermore, these types of devices are usually uncomfortable, unsightly and sometimes difficult to adapt to the physiognomy or facial dimensions so variable that there may be between users.

Explanation of the invention

The recommended nasal filter for viruses, bacteria and other microorganisms fully satisfactorily solves the aforementioned problems, based on a simple but highly effective solution.

For this, and more specifically, the filter of the invention is embodied in a tubular body, which may have a cylindrical, truncated cone, oval, elliptical or any section that allows a certain adaptation to the internal walls. of the nose depending on the different anatomical variants that it usually presents (leptorhine, mesorhine and platyrhine), a tubular body in which a layer of a filtering element is preferably incorporated on one of its bases, leaving the other open.

The filter is inserted into each of the nostrils in a way that allows the use of the mouth to do any of its own functions, speak, drink, etc., so that it You just have to be aware of breathing in through your nose and breathing down through your mouth, eliminating the aerosol effect, although you can also breathe out through your nose.

The objective is to prevent the filter from moving and its accidental expulsion, thereby avoiding the entry of air between the nasal mucosa.

The filter layer of this can be placed inside or outside the nostril. It is recommended that it be inside to avoid possible expulsion or movement of the cylinder.

Given that the physiognomy of each user is different, and although the device can be manufactured in different sizes, it has been foreseen that it is slightly undersized externally, so that in its adaptation to the nose it determines a small clearance, a clearance that is It will be eliminated by including an external ring of polyurethane foam, rubber, or spongy material that will not allow it to act as a sealing gasket, preventing the passage of air through another place other than the filtering area of the device.

The filtering layer of the device will be made of an appropriate material, of the same type as those used in current multi-layer masks (polypropylene, cotton, etc.) and of the P2 type.

The tubular body will have a diameter between 2 and 20 millimeters, a length between 1 mm and 100 mm and a wall thickness between 0.1 and 2 millimeters depending on the characteristics of the user's nostrils.

This must have the elasticity, adherence and anchorage so that it is attached to the inside of the nostril and does not move or come out.

In this sense it has been provided that optionally it can incorporate on its external face and in correspondence with the adaptation ring an adhesive of the type used for other medical activities.

According to another variant embodiment of the device, it could include an external arm or clip that fits around the edge of the nose, duly immobilizing the device.

The material of the device can be a plastic currently used in medicine such as PVC, polyethylene, polypropylene, etc. or aluminum, stainless steel, graphene, etc.

As for the filter layer, it can be immovably attached to the cylinder or have a removable character, by means of a threaded ring, glued or clipping elements.

To ensure the proper functioning of the device, it has been foreseen that it initially comes assisted with a removable seal that seals the inside of the tubular body, in order to ensure that once the device is implanted, the air does not enter through the gap that is defined. between the outer wall of the device and the inner walls of the nose, an area that is isolated through the aforementioned foam ring.

Once the watertightness of the device has been verified, the seal can be removed, the device becoming fully functional.

It only remains to point out, finally, that the device may be impregnated with a product that prevents nasal congestion.

In this way, an extremely versatile, comfortable device is achieved, which goes unnoticed, safe and economical.

Brief description of the drawings

To complement the description that is going to be made below and with the aim of helping a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, 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 perspective view of a nasal filter for viruses, bacteria and other microorganisms made in accordance with the object of the present invention.

Figure 2.- Shows a view similar to that of figure 1, but corresponding to a variant embodiment of the device, and in which it appears with its seal removed.

Preferred embodiment of the invention

In view of the outlined figures, it can be seen how the nasal filter of the invention is made from a body (1), in this example of a cylindrical tubular configuration, without discarding the previously described configurations, which could be made of aluminum, with a merely exemplary diameter of 5 mm and a height of 10 mm, with a wall thickness of 1mm, and that in correspondence with one of its bases includes a sheet (2) of filter material, type P2 or any other filter material commonly used in the field of practical application of the invention.

The aforementioned tubular body (1) is finished off at its lower end in a plastic seal (3) intended to initially check the correct tightness in the implantation of the device on the nostrils of the user.

To adapt to the variable configuration of said pits in a stable way, it has been provided that externally to the tubular body (1) and at any suitable height, a ring (4) of polyurethane foam, rubber, or spongy material is established, which acts as gasket for air.

As previously said, and in accordance with the variant embodiment of Figure 2, the body (1) could include an arm (5) acting as a clip, which allows increasing the degree of stability of the device in its position. implantation on the nostrils, arm (5) of an elastic nature, intended to embrace with a certain degree of pressure the external contour of the edge or mouth of the corresponding nostril.
