DESCRIPTION

Filtering nasal mask

TECHNICAL SECTOR

The present invention falls within the technical sector of personal protective equipment (EPIS); PPE (Personal Protection Equipment) means any equipment intended to be worn or held by the worker to protect him from one or more risks that may threaten his safety or health, as well as any complement or accessory intended for that purpose. . In this case, the invention seeks the protection of any person, to limit the risk of contagion due to germs, bacteria, viruses, small toxic particles that may be suspended in the environment; the hygienic-sanitary sector is of any field: work, educational and domestic and in some models it provides a germicidal and anti-toxic power on the inspired and expired air.

This invention fits in the sector that corresponds to current necessities of life, in particular garments and articles of protection and hygiene, within the sector of the industry dedicated to the manufacture of hygienic protection equipment and has a possible application in medicine both for facilitate the work of health personnel as well as for patient treatments.

STATE OF THE ART

Nasal mask with filter and diffused air curtain

The use of air as a means of disinfection, detoxification and as a barrier against pathogens and viruses is becoming evident in 2020/21 from the pandemic suffered.

Pursued objectives:

(A) prevent impurities or contaminants from entering directly or indirectly into the respiratory tract, through the eyes, mucous membranes, through the skin or through the wounds of the user.

(B) protect others from being exposed to pathogens and other exhaled contaminants exuded by the wearer. They are of different degrees of protection.

(C) Facilitate the application of treatments.

To achieve the first purpose, filtered airflow diffuser devices are used in an environment where the air contains particles harmful to health. This scope includes FFP masks.

To accomplish any of these goals, the respirator must be able to stay snug against the wearer's face. To achieve a good fit, filtering face masks generally have a headband that extends laterally from the mask around the back of the wearer's head and neck.

There are masks of a textile nature, which protect the user's mouth and nose and which are obviously fixed to the head by different means, as well as masks made from a body of spongy material in a single molded piece, which constitutes a kind of cup that it adapts to the aforementioned facial area and which is also fixed to the user's head by any appropriate means.

Filtering-face-pieces or ffp masks protect the user as they are designed to filter particles, liquid aerosols and pathogens present in the environment, preventing them from being inhaled by the user. Depending on the filtration efficiency, the mask is class 1, 2 or 3. The filter material is made up of a network of plastic fibers which retains the contaminant; they have an added polarity that decreases with use and humidity.

The novelty of the invention object of this application is a filtering nasal mask that can include in the opening (to breathe through the nose) a frame for a lid with a filter and/or a window for a window sheet with a filter. The invention allows the user to protect the nose, makes it easier to eat, drink, talk or smoke. The applicant only knows the Utility Model with the file MX/u/2021/000077 that can be considered; said model is similar to a surgical mask for the nose.

The only files found that use the external fan air conditioner are ES-2778000_A1 and ES-2797248_A1. The own utility models in process are U202031962, U_202032100, U_202130311.

The Mexican Institute of Industrial Property (IMPI) granted the researchers the registration as a Utility Model with the file MX/u/2021/000077 Mask Eating nasal mask, said mask has differences from the invention defended here.

BRIEF EXPLANATION OF THE INVENTION

The novelty of the invention lies in the use of a filtering nasal mask (alone in its simplest form or combined with other PPE for which it is dimensioned).

The filtered air diffuser mask creates a curtain of filtered air in front of the mouth and can include disinfectant, toxin neutralizing, regenerative, therapeutic, and relaxing techniques. The diffuser device for a filtered air flow comprises a tubular support structure (1ST) that houses a plurality of holes and/or slots responsible for diffusing the filtered air for the formation of the air curtain. The filtering nasal mask can house its own diffuser device for a filtered air flow made up of an air intake, filter, drive motor, propeller, battery, ducts and ejection holes and/or slots.

The invention can be a single block or be made up of different modules.

The embodiment uses EPA filter. The HEPA (High Efficiency Particle Arresting) air filter can remove viruses and most harmful particles, including mold spores, dust, dust mites, pet dander and other irritating airborne allergens.

Functions of the diffuser device for filtered air in indoor and outdoor spaces

1) Filtering: prevents harmful or toxic particles and viruses, bacteria and other pathogenic elements from affecting the user.

2) Germicide: it destroys viruses, bacteria and pathogenic elements if the air passes through the pipe with UV led (ultraviolet led)

3) Protect

4) Prevents spread of viruses or bacteria

5) Allows confinement at home with relatives

6) Facilitates the use of the mask

7) Facilitates social interaction

THE REALIZATION PART OF THE FOLLOWING ELEMENTS:

- PROTECTIVE COVER that defines a safe breathing zone and that adapts ergonomically to the user's face; reusable, easy to clean because it is made of materials that can be cleaned with simple soap and water or alcohol, except for the filter element that can be easily renewed, removing it from the encapsulation and replacing it with a new one. The invention may have windows in the mask. The masks include flexible joints to prevent air leaks from outside to inside or vice versa, they are usually made of medical silicone.

- FILTERED AIR FLOW DIFFUSER DEVICE. The filtered air is driven by a motor with propellers, passes through ducts that reach holes in the tubular support structure of the device and is expelled. In this closed circuit, the air after being filtered can be enriched (even with filtered air from outside) with bactericidal and antiviral substances or with ions that destroy viruses, bacteria and pathogenic agents without being harmful to the user. filtered air curtain Filtered air can be diffused through holes and/or slots (2a) to protect an area and/or can create a filtered air curtain

- FILTERED AIR FLOW DIFFUSER DEVICE VENTILATOR: serves to create an air curtain and/or create a zone of diffused air in front of the mouth that protects the respiratory tract. The fan is made up of at least one propeller (3h) driven by a motor (3m). The fan is powered by a battery powered by electrical connection, micro-USB type, located in the tubular support structure (1ST) or in the protective cover.

- BREATHING FAN: it will provide purified air through a breathing filter or send purified and disinfected air away from the protected area (to avoid contagion).

- FASTENING ELEMENTS to the user's face and/or head.

- FILTERS, prevent harmful or toxic particles and viruses, bacteria and other pathogenic elements from affecting the user.

- MECHANISMS, MEANS AND GERMICIDE AND ANTI-TOXICITY SUBSTANCES: ultraviolet LED

- MECHANICAL AND/OR ELECTRONIC ELEMENTS.

Figure 2: An example of a filtering nasal mask with a diffuser device for a flow (8f) of filtered air.

PREFERRED EMBODIMENTS OF THE INVENTION

Figure 1, simplified diagram of a type of filtered air flow diffuser device: from the air intake (2t) (figure 1), filters (3a), propeller (3h) driven by motor (3m), ducts (2c) ejection and ejection holes and/or slots (2a). In this scheme the air intake, the filter and the propeller are very close; if there is a distance there will be a suction duct that joins them. The supporting tubular structure is indicated by (1ST).

Figure 2: Example of an embodiment of a filtering nasal mask (1n) with filtered air flow diffuser device; It has air intakes (2t), filter (3a), motor (3m) and propellers (3h) that directs a flow (8f) of filtered air downwards thanks to some holes and/or expulsion slots (2a) protecting it from a mouth infection when eating and drinking and talking without a mask. There is a filter (1f) to breathe through the nose: this filter is changed after it expires. There is an opening in the lower horizontal plane (not seen in drawing 2) where the filter (1f) fits. The opening can be sealed by a filter cover or said opening can include a window that includes a filter window sheet that makes the filter function (1f).
