Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] For a more detailed description of the invention, a description of specific possible embodiments thereof with the corresponding drawings is now described.

[0021] FIG. 1 shows a front view of an apparatus for protecting respiratory organs made according to the invention.

[0022] FIG. 2 shows a rear view of an apparatus for protecting respiratory organs made according to the invention.

BEST EMBODIMENTS OF THE INVENTION ARE DESCRIBED

[0023] In a preferred embodiment of the invention, the respiratory protection device comprises a helmet 1 comprising a transparent mask 2 and a flexible membrane 3, an air ventilation tube 4, an incoming air cleaning device 5, a supply tube 6, a pressure regulating valve 7, a discharge tube 8, an outlet air cleaning device 9, a rigid section 10 of the air ventilation pipe 4, a flexible section 11 of the air ventilation pipe 4, an air inlet hole 12 in the helmet 1, and an air discharge opening 13 (FIG. 1, 2).

[0024] The device for protecting the respiratory organs functions as follows.

[0025] Ambient air is supplied to helmet 1 with mask 2 from incoming air cleaning device 5 located on helmet or user's body, which filters external air, increases its pressure, and under increased pressure supplies air through valve for regulation of pressure 7 into supply tube 6. Then air gets into flexible section 11 of front tube for ventilation 4, and then enters its rigid section 10, after which air enters helmet 1 through introducing air 12. Inside helmet 1 external air is inhaled by the user. The user exhales through holes for venting air 13 in rigid section 10 of rear tube for ventilation 4. The air enters flexible section 11 of this tube for ventilation 4 and then enters discharge tube 8, from which it is supplied to device for cleaning of outgoing air 9, located on helmet or body of user, which cleans internal air from aggressive biological substances exhaled by user and outputs the purified air to the outside (FIG. 1, 2).

[0026] Also, the device for protecting the respiratory organs can have a unit for monitoring the operation of the device (not shown in the figures) with a device for indicating the malfunction of the device, which, in the event of a deviation of the operating modes of the device, comprises signalling the device malfunction.

[0027] In this way, the user's breathing is carried out with air passed through the external air cleaning device 5 with the required level of cleaning. At the same time, due to excessive pressure inside the helmet 1, air is excluded from outside, bypassing the device for cleaning incoming air, which significantly increases the tightness of the claimed device.

[0028] The presence of the device for purifying outgoing air 9 minimizes the presence of aggressive chemical and biological substances exhaled by the user in the air, which has passed through the claimed device, which significantly expands the functionality of the claimed device, makes it possible not only to clean incoming air, but also to clean from biological substances and output air from the device air.

[0029] The presence of a pump with an electric or mechanical drive for the operation of the incoming air cleaning device 5 makes it possible to reduce the load on the user's respiratory system, wherein the load does not exceed the load during normal breathing of the user without the use of the claimed device.

[0030] Use of helmet 1 and mask 2 around head excludes touching of mucous membranes and skin of user's face with possible contaminated internal surface of helmet 1 and mask 2, and flexible membrane 3 provides tight adjacency of helmet 1 to user's body.

[0031] Possible presence in the claimed device of quartz lamps provides additional disinfection of air outside the device. In this case, the specific mark of the quartz lamp is selected according to the conditions of the environment in which this device is to be used for as well as to the degree of cleaning.

[0032] The use of the claimed device by a several people at the same time in the same place makes it possible to significantly reduce the possibility of transmitting chemical and biological substances by an air-droplet method, which allows members of such groups to interact with each other, excluding the possibility of mutual contamination.

[0033] The use of the claimed device by the individual user makes it possible to protect its respiratory organs from external action and to exclude the transfer of chemical and biological substances inherent thereto by an air-droplet method.

[0034] The design of the claimed device for protecting respiratory organs makes it attractive for wearing in everyday life, in transport and in entertainment events.

[0035] The distinctive feature of the claimed device for respiratory protection is the presence of a ventilation system which is provided by tubes for ventilation 4, and provides a user with clean external air and purifies the air exhaled by the user, wherein the most massive parts of the device are placed on the user's body, and the mask 2 does not come in contact with the skin of the face.

[0036] As will be appreciated by those skilled in the art, the present invention is easy to design in other specific forms without departing from the essence of the present invention.

[0037] The present embodiments are merely illustrative and not restrictive, the scope of the invention being represented by the claims, and it is intended that all possible changes and areas of equivalency of the claims are intended to be included therein.
