Description

Breathing device
The invention relates to the means of life support, namely, devices for protecting the human respiratory system from the harmful effects of an unfit for breathing, toxic and smoke-laden gaseous medium, and, in particular, can be used in the manufacture of breathing apparatus operating on compressed air or oxygen.
Known in the Prior Art are various designs of respiratory devices. In particular, in patent [1], in the medical respiratory apparatus containing a protective mask, a device for supplying air and an air opening, which can be closed by a valve (reducing the patency of this opening), thus changing the composition of inhaled air (increasing the concentration of CO2). In patents [2, 3], the breathing apparatus are disclosed, each containing a protective mask and a bottle with breathing gas, a response to pressure that is excessive compared to the pressure of the outer atmosphere outside the mask is provided.
The disadvantage of these and many other designs is the lack of giving attention to environmental parameters.
The nearest Prior Art reference is the breathing device according to patent [4|, which contains an environmental analysis device, a respiratory mask with a flow regulator for connection to a source of compressed oxygen through a supply pipe and gas flow control means. The device for analyzing the state of the environment is made in the form of an aneroid box, which is sensitive to environmental pressure. It is equipped with a tapped rod, which provides for the forced opening of the valve at the time when the environmental pressure drops below a predetermined value (depressurization of an aircraft cabin). An additional amount of gas is supplied in this design not for breathing, but into the head-harness of the mask, ensuring its stretching and quick donning of the mask.
This device takes into account the change in air pressure as an environment condition. At the same time, there is no possibility to set individually the limits of the parameter being controlled.
In large cities and megacities, in confined spaces with the concentration of oxygen consumers, in some industries, etc., in addition to air pollution, there is also a decrease in the oxygen content in the air.
The object of this invention is precisely dosed automatic oxygen supply to the inhaled air with the possibility of individual adjustment and automatic maintenance of the set level of oxygen in the inhaled air.
The problem set in the breathing device containing a device for analyzing the condition of the environment, a breathing mask with a flow regulator for connecting to a source of compressed oxygen by means of a supply pipe and gas control means is solved in that the device for analyzing the condition of the environment is made in the form of sensors of oxygen content in the environmental air, and the gas supply control means is made in the form of an electronic programmable control device the inputs of which are connected to the said sensors, and the output is connected to the flow regulator.
The breathing device is preferably provided with an inhaling valve configured with the possibility to generate signals for the beginning and end of the inhalation and apply the said signal to the additional input of the electronic programmable control device.
The electronic programmable control device can be equipped with a wireless communication module for communication with the user's smartphone for input/output of information.
The attached non-limiting drawings present an example of implementation of the claimed device.
Fig. 1 shows the front view of the embodiment of the claimed device J
Fig. 2 shows the side view of the embodiment of the claimed device
The device is made up of the breathing mask 1 worn on the face and covering the mouth and nose, with a flow regulator 2 for connecting to a source 3 of compressed oxygen through a supply pipe 4. The device for analyzing the condition of the environment is made in the form of sensors 5 of oxygen content in the environmental air. The gas supply control device is made in the form of an electronic control device 6 the inputs of which are connected to the said sensors 5, and the output is connected to the flow regulator 2.
The device, which determines the time of beginning of inhalation and end of inhalation, is made in the form of an inhalation valve 7, which, in the open state, allows air to enter the mask 1 and, in the closed state, prevents the escape of exhaled gas. The valve 7 is equipped with a closing sensor (not shown in the drawing), transmitting data to the control device 6;
Also, the mask is equipped with valves 8 for exhausting the exhaled air.
As the sensors 5 of oxygen content in the environmental air, any automatic gas analyzers of continuous action, suitable in size, weight and performance specification can be used, for example: [5]. The sensors 5 are installed on the outer surface of the mask 1.
The electronic program mable control device 6 is wired to the sensors 5 of oxygen content in the environmental air and receives from them data on the oxygen content in the environment air; it is also wired to the valve 7 and receives from it data on the beginning and end of inhalation. Also, the device 6 may have a wireless communication module (not shown in the drawings) for communication with the user's smartphone for input/output of information. On the basis of the program embedded in the device 6 and the user's settings, the device 6 issues control com mands for opening and closing the flow regulator 2 for starting and stopping of the supply of oxygen. It has a small size and weight, and is attached to the mask in any location. The sensors 5 of oxygen content in the environment air, the electronic programmable control device 6, the flow regulator 2 and the breath valve 7 use for their operation the electric power of the portable source (not shown in the drawings), for example, a battery. The specified portable source can be either part of mask 1 or a separate device connected to consumers by wires.
The operating procedure of the device:
1) The user sets the desired level of oxygen content in the air breathed in through the mask by entering data into the control device 6.
2) The sensors 5 of oxygen content in the environment air determine the levels of oxygen in the environmental air and transmit data to the control device 6.
3) The user begins to inhale, the inhalation valve 7 is activated and transmits to the control device 6 a signal on the beginning of inhalation.
4) Comparing the information received from the user to the information received from the sensors 5 of oxygen levels in the environment air, the control device 6 decides on the beginning and duration of the supply of oxygen inside the mask into inhaled air.
5) If the oxygen content in the environment air is equal to or exceeds the level set by the user, the control device 6 decides not to supply additional oxygen under the mask 1.
6) The control device 6 transmits a command to the flow regulator 2 to start supplying oxygen.
7) The flow regulator 2 opens at the source 3 of compressed oxygen. Oxygen is supplied under the mask 1.
8) The control device 6 transmits a command to the flow regulator 2 to terminate the supply of oxygen.
9) The flow regulator 2 closes at the source 3 of compressed oxygen. The supply of oxygen under the mask 1 is terminated. 10) The user finishes inhaling, the inhalation valve 7 is activated and transmits a signal on the end of inhalation to the control device 6.
Using the technical decision claimed, the user can compensate for the lack of oxygen in the inhaled air. For example, if the user sets the oxygen level to 21.1% (the generally accepted norm), then when the oxygen level in the environment air decreases, the device will automatically bring the oxygen level in the inhaled air to the preset one.
Using the technical decision claimed, the user can temporarily increase the oxygen content in the inhaled air to the levels exceeding the generally accepted norm of 21.1% for arbitrary, independently determined purposes (therapeutic, sports-related, etc.).
