Description

Illlltllllt

The invention relates to medical technology, in particular to breathing devices for therapeutic breathing mixtures.

The aim of the invention is to maintain the desired concentration of carbon dioxide.

The drawing shows a device for breathing air with a high content of carbon dioxide.

The device contains a cylindrical body 1 and a mask 2 with connecting elements 3 and 4. The body is made in the form of a cylinder, in the base 5 of which there are openings for connection with the atmosphere, and in the base 6 there are openings for connection with 2. The walls of housing 1, base 5 and 6, and side surface 7 are made of thermally insulating material. Inside the housing 1 is a filter 8 of carbon dioxide, which has desorption properties.

The filter 8 can be made of an activite into the environment; as a result, the temperature of the filter 8 reaches a constant value close to the temperature of the exhaled air rather quickly. The location of the inclusions 9 in the most distant part of the mask 2 of the housing 1 ensures uniform heating of the entire filter 8 to the specified temperature. After Toroi, as filter 8 absorbs a sufficient amount of carbon dioxide, it begins

10 is released into the inhaled air, which ensures the desorption properties of the material from which the filter 8 is made. The temperature of the filter significantly increases the desorption properties of the filter 8 and the required amount of carbon dioxide enters the inhaled air, the concentration of which is kept constant during patient breathing. The required concentration is determined by the size of the filter 8, the number of inclusions 9 and intensively carbon impregnated with 3-5% impregnation with 3-5% aqueous solution of sodium bicarbonate or potassium or sodium bicarbonate.

Claims 1. An apparatus for breathing air from which is located in the most distant — an elevated carbon dioxide content; “..“ “,,., .. ,, D.,“ t About ITT tld 1 lg g gtl7n g ptoog tikl pt about p mask part of the filter. The breathing apparatus operates as follows. The patient begins to inhale and exhale through mask 2. When you exhale, the air that contains carbon dioxide passes through filter 8, as a result of which carbon dioxide is adsorbed on the particles of activated carbon that the filter 8 consists of. - low volume materials that are heated by contact with warm exhaled air, the temperature of the filter 8 begins to rise. Walls 5, 6 and 7 of the heat insulating material prevent the loss of 35 40 containing a housing with an opening for connection with the atmosphere and a mask, characterized in that, in order to maintain the required concentration of carbon dioxide, it is provided with a filter with desorption properties in the housing and containing inclusions of heat-intensive material, most of which are located in the part filter, while the walls of the housing are made of insulating material. 2. An apparatus according to claim 1, characterized in that the carbon dioxide filter is made of a sorbent-activated angle impregnated with a 3-5% aqueous solution of sodium bicarbonate or potassium. heat into the environment, as a result, the temperature of the filter 8 reaches a constant value close to the temperature of exhaled air, rather quickly. The location of the inclusions 9 in the outermost part of the mask 2 of the housing 1 ensures uniform heating of the entire filter 8 to the specified temperature. After Toroi, as filter 8 absorbs a sufficient amount of carbon dioxide, it begins release into the inhaled air, which ensures the desorption properties of the material from which the filter 8 is made. The temperature of the filter significantly increases the desorption properties of the filter 8 and the required amount of carbon dioxide enters the inhaled air, the concentration of which is kept constant during the patient's respiration. The required concentration value is determined by the size of the filter 8, the number of inclusions 9 and the intensive-intensity diseases of the useful, Claims 1. Air breathing apparatus according to ITT, tdl 1 lg g gtl7n g ptoog chit pt o r 0 containing a housing with an opening for connection with the atmosphere and a mask, characterized in that, in order to maintain the required concentration of carbon dioxide, it is provided with a filter with desorption properties in the housing and containing inclusions of heat-intensive material, most of which are located in the part filter, while the walls of the housing are made of insulating material. 2. An apparatus according to claim 1, characterized in that the carbon dioxide filter is made of a sorbent-activated angle impregnated with a 3-5% aqueous solution of sodium bicarbonate or potassium.
