MASK WITH ULTRAVIOLET DISINFECTION OF INHALED AND EXHALED AIR

Abstract

The mask with ultraviolet disinfection of inhaled and exhaled air in the form of a filtering-purification protective front surface contains a removable unit, the inner surface of which is covered with an ultraviolet radiation source with a pluggable independent power supply system. The filtering-purification unit has rows of meshes composed of light guides of ultraviolet radiation spectrum with tapped radiation in each cell of the mesh, and a source is brought to the meshes. The mask itself can be made of a mesh composed of light guides. The mask in the form of a shield in front of the face is represented by a mesh composed of light guides in front of the face or along the entire perimeter. The mask along the bottom part of the headband, above the face, is provided with a LED strip of ultraviolet radiation spectrum, radiation being directed downward, the sector of directed radiation being adjustable. The headgear can serve as a headband. Also, the LED radiation strip is attached to the eyeglasses along the perimeter of the spectacle frame.

Claims

1. A mask with ultraviolet disinfection of inhaled and exhaled air, which has an opening for inserting a filtering-purification unit for purifying inhaled air as well as a headband with elements for attaching the respirator to the user's head, characterized in that the filtering-purification unit is designed to be removable and hermetically fastenable in the mask opening, and the inner surface of the replaceable unit is covered with an ultraviolet radiation source with a pluggable independent power supply system.

2. The mask according to claim 1, wherein the filtering-purification unit has rows of meshes composed of light guides with tapped radiation in each cell of the mesh, and a source of ultraviolet radiation is brought to the light guides.

3. The mask according to claim 2, wherein the entire surface of the mask is designed as a mesh composed of light guides, which is fastened to the frame.

4. The mask according to claim 3, wherein a mesh composed of light guides is fastened to the rim of the headgear.

5. The mask according to claim 4, wherein a tape of LED radiation is laid along the lower part of the rim of the headgear.

6. The mask according to claim 5, wherein the sources of LED ultraviolet radiation on the rim of the headgear have adjustable sectoral directed radiation.

7. The mask according to claim 5, wherein the LED strip of ultraviolet radiation is attached to the eyeglasses along the perimeter of the spectacle frame.

Description

EXAMPLE EMBODIMENT

[0010] FIG. 1 shows a mask with replaceable disinfecting units, FIG. 1a shows a removable unit with a mesh composed of light guides with side glow; FIG. 1b shows a removable purification unit with a source along the inner perimeter, front view; FIG. 1c shows a removable unit with a mesh composed of light guides, front view; FIG. 2 shows a mask composed of light guides, FIG. 3 shows a headband rim with an ultraviolet “curtain”, FIG. 4 shows versions of the ultraviolet “curtain” (shield) on headgears, including those in FIG. 4a—on a baseball cap, in FIG. 4b—on a mosquito net hat, where: 1—a mask, 2—a removable purification unit, 3—an ultraviolet radiation source, 4—a mesh composed of light guides, 5—direction of ultraviolet radiation.

[0011] The respirator is operated as follows.

[0012] A removable purification unit 2 is inserted into mask 1. In the removable purification unit 2, an ultraviolet radiation source 3 is disposed on the inner surface, the radiation of this source being directed from the periphery of the removable purification unit 2 to the center. When the mask 1 is attached to the face, the inhaled and exhaled air passes through the removable purification unit 2. The air that passes through the removable purification unit 2 is exposed to wave irradiation of ultraviolet spectrum. When inhaled, the disinfected air enters the human respiratory system. When exhaled, the air from the human respiratory system passes through the removable purification unit 2 and is also exposed to ultraviolet irradiation, which disinfects the air to be exhaled into the environment.

[0013] In the system purification unit 2, a mesh 4 composed of light guides in one or more layers perpendicularly to the air movement direction can be used instead of the ultraviolet radiation source 3. In this case, the inhaled and exhaled air thanks to passing through the mesh has a closer contact with the ultraviolet radiation source, because there is a side radiation outlet inside the cell in each cell of the mesh in the mesh 4 composed of light guides. Disinfection in this case may have a higher level.

[0014] An ultraviolet “curtain” attached to the head can be used for disinfection of inhaled and exhaled air (FIG. 3, 4). Structurally, the ultraviolet “curtain” is a rim or the like attached to the head. Ultraviolet radiation from the source disposed along the perimeter propagates directionally downwards from the rim. Also, a mesh composed of light guides with ultraviolet radiation with side glow in each cell of the mesh directed to the interior of the cell can be used.

[0015] It is also possible to dispose the LED strip along the perimeter on the rim along the entire perimeter or only on the front part with the radiation being directed in a narrow sector.

[0016] The inhaled and exhaled air passes through the UV treatment area and undergoes disinfection. The version with a LED strip increases the mobility of application of such disinfection. The LED strip can be used on almost any headgear: hat, flat cap, baseball cap, mosquito net hat etc. The use of LED strip of an ultraviolet radiation spectrum that is safe for humans decreases limitations of field of use.
