This respiratory mask tightly covers mouth and nose. It consists of at least two layers of medical fabric. It can also be manufactured with N95 mask technology. The mask features a breather with a special cap. By opening this cap, air reaches the mask wearer through the breather. A tablet, covering the breather opening tightly, is placed inside the aforementioned breather. The tablet is saturated with medical material or odor for inhalation. The tablet allows air to pass through it. By controlling the slots on the breather cap, air can be allowed to pass through the tablet for the mask wearer. Medical or odor tablets are placed in their own tight packets. After opening the packets, the tablet is placed inside the breather, and then the breather cap is installed so that the user can inhale the medical material or odor as long as the user wears the mask.

The utility model discloses an edible protective mask, and relates to a mask, in particular to an edible protective mask which comprises a mask body, a covering piece and a nasal plug assembly. The mask body is provided with ear hanging belts, an opening, a covering piece and a fixing female buckle. The ear hanging belts are arranged on the two sides of the mask body. The opening is formed in thecorresponding position of the mouth of the surface of the mask body. One side of the covering piece is fixed to the mask body, the covering piece is matched with the opening, and the other side of thecovering piece is matched with the fixing mother buckle through the fixing son buckle. And the nasal plug assembly is inserted into the nostrils through the opening of the mask body. When the food packaging box is used, a protection effect can be achieved during food taking, and the food does not need to be completely removed; due to the nose openings, fog cannot be generated when the glasses areworn in winter; the structure is simple, the manufacturing is easy, and the discomfort cannot be caused after long-term wearing. In a relatively safe environment, the nose plug can be taken down whenthe nose is not in good time, and other parts can still be protected.

FIELD: chemistry. SUBSTANCE: invention relates to the technology of producing chemical substances used in rebreathers on chemically bound oxygen, and can be used in production of products for regeneration of air based on potassium superoxide. Regenerative product for rebreathers includes potassium superoxide and magnesium silicate, obtained from chrysotile asbestos, with ratio of components in the composition of the regenerative product, wt%: chamber potassium superoxide KO2 90–95; magnesium silicate MgSiO3 5–10. Method of producing a regenerative product for rebreathers involves mixing potassium superoxide with magnesium silicate, followed by molding a mixture, wherein magnesium silicate is obtained from chrysotile asbestos by exposure to temperature of 800±20 °C for 2-3 hours with subsequent grinding in a drum mill. After molding, the regenerative product can be thermally stabilized according to: heating to 200±20 °C at rate of 1–5 °C/min; exposure at 200±20 °C for 1–2 hours. Regenerative product of the presented composition provides, during operation in the composition of the rebreather, a low average and maximum volume fraction of carbon dioxide on inhalation, a low temperature of the regenerated air on inhalation and a longer time of protective action. EFFECT: this provides more comfortable conditions for the user and allows to significantly expand the range of persons who can use these rebreathers. 3 cl, 1 dwg, 2 tbl, 3 ex
