Description

Technical field

The utility model relates to devices for recording human respiratory cycles and transferring them to a computer device, which is achieved by comparing the temperature of the exhaled and inhaled air with the ambient temperature, electronic conversion of the received signal and its subsequent transmission through the communication channel for recording in electronic form, as well as for display on the screen in the form of pneumograms and / or computer games. The device and its software provide simultaneous display of recorded and current respiratory cycles in one standardized scale.

The technical result is the possibility of conducting respiratory biocontrol: a) by arbitrary adjustment of respiration, displayed in the form of the current pneumogram, in accordance with a previously recorded pneumogram; b) by holding computer games in which control is carried out by breathing, and the game result is the coincidence of the current pneumogram with a previously recorded pneumogram.

Biofeedback or adaptive biofeedback is a well-known psychophysiological method for voluntarily changing physiological parameters in accordance with some given values. The method is based on the principle of biological feedback, therefore, in the English literature it is known as the BioFeedback method (1). Respiratory biocontrol is characterized in that the parameters of the external respiration system are used as controlled parameters, for example, a pneumogram reflecting the structure of the respiratory cycle (2).

State of the art

Currently, for monitoring breathing and respiratory biofeedback, separate sensors for each nostril are used to detect the flow of breathing, electronic circuits to amplify and increase the detected signal, and stereo headphones bring this information to the user's ears (3) (U.S. Patent No. 4,924,876, 1990). A disadvantage of the utility model is the absence of a mouthpiece, which forms a flow and protects the sensors from external ambient flows, which significantly reduces the accuracy of the display of the structure of respiratory cycles, as well as the inability to record and subsequent playback of respiratory cycles simultaneously with the current breath recording.

Also known is the sensor used for breathing training in the form of a chest belt (4) (China Patent No. 2015543180 U, 2010) consisting of a tensile sensor and an elastic connecting strip. When breathing, the chest changes its geometry and data about breathing is transmitted to the computer. The disadvantages of the utility model is that additional artifacts of body movement interfere with the useful breathing signal, as well as the inability to record and subsequently play breathing cycles simultaneously with the current breath recording.

Also known is a sensor used to monitor the flow of air passing through the respiratory tract, which is not sensitive to moisture and / or does not come into contact with the skin (5) (US Patent No. 5195529, 1993). The sensor according to the invention is located near the nasal inlets. The disadvantage of this method is the lack of a mouthpiece that forms a stream. In addition, the device does not provide for recording and subsequent playback of respiratory cycles simultaneously with the current breath recording.

Also known is the oral-nasal respiratory sensor (6) (China Patent No. 202446085 U, 2012) mounted on the head with the installation of the actual sensing element in front of the nose and mouth. This useful model restricts head movements and creates discomfort for a person, and the absence of a mouthpiece forming a flow reduces the accuracy of displaying a pneumogram. In addition, the device does not allow you to record and play breathing cycles simultaneously with the current breath recording.

A known method of monitoring breathing using a set of respiratory sensors (7) (US Patent No. 5069222, 1991). In accordance with this invention, the sensor only works with the monitor and is designed to detect human breathing. The communication device provides the connection of the output signals from the first and second elements that are responsive to breathing, to the monitor and allows the monitor to display the breath, which is determined by the first and second elements that are sensitive to breathing. The disadvantage, as with previous devices, is the lack of a mouthpiece forming a flow, and the inability to record and play breathing cycles simultaneously with the current breath recording.

The closest analogue is the device described in the research work (Grishin O.V., Kovalenko Yu.V., Grishin V.G., Variability of pulmonary gas exchange and respiratory rhythm // Human Physiology. 2012. V.38. No. 2. S.87-93). It contains headphones, an electronic converter, a communication channel with a computer device, a flexible headset, an air flow tube with a temperature sensor, a movable mount between the tube and headset, which allows you to get a pneumogram that can be recorded and played.

However, the described design does not have a second temperature sensor that measures the ambient temperature, which does not provide simultaneous playback of the recorded pneumogram with the current pneumogram in one standardized scale, which makes it impossible to conduct respiratory biocontrol, as well as to develop computer games controlled by breathing.

Utility Model Disclosure

The objective of the device for recording and displaying respiratory cycles in the form of pneumograms and computer games is the ability to simultaneously play back the recorded pneumogram with the current pneumogram in one standardized scale, which makes it possible to conduct respiratory biocontrol, as well as the development of computer games controlled by breathing.

The problem is solved in that in a device for recording and displaying respiratory cycles in the form of pneumograms and computer games containing headphones. an electronic converter, a communication channel with a computer device, a flexible headset, an air flow tube with a temperature sensor (D-1), a movable mount between the tube and a headset, according to a utility model, there is a second temperature sensor (D-2) located in the headphone housing, and a software security.

D-1 - temperature sensor for inhaled and exhaled air and D-2 - ambient temperature sensor. Both sensors are based on a highly sensitive, low-inertia thermosensor with a reaction to a temperature change of less than 1 second, which ensures high accuracy of the display of respiratory cycles in the form of current and recorded pneumograms.

Temperature measurement with a tube temperature sensor (D-1) allows you to measure the amplitude of the inhaled and exhaled air. At the same time, the simultaneous measurement of the ambient temperature with a D-2 temperature sensor allows you to take into account changes in this temperature to convert the amplitude of each recorded and current pneumogram into one standardized scale. This ensures the simultaneous reproduction of the current pneumogram and any recorded pneumogram in one standardized scale, which is a necessary condition for respiratory biocontrol.

The device is placed on the head like ordinary headphones (figure 1) and consists of (figure 1, 2):

a) a device based on headphones (1) with a flexible headset (2) and a tube forming a stream (3),

b) the temperature sensor D-2 (4) located in the headphones (1);

c) a movable mount between the tube and the headset (5), which allows the tube to rotate around the axis of the headset, which allows you to adjust its position for convenient placement directly at the entrance to the nasal passage,

d) temperature sensor D-2 (6) located inside the tube (3),

e) a removable mouthpiece (7) located at the end of the tube (3).

f) a communication channel with a computer device in two versions - a radio channel and a wired channel

g) software for communication with a computer device (personal computer, laptop, tablet, smartphone, etc.), converting respiratory cycles into electronic files and bringing them to one standard scale for separate and simultaneous display in the form of pneumograms, as well as in the form of controlled breath of computer games.

Figure 3 presents a "screenshot" of the screen during respiratory biocontrol by pneumatic code. The curve of the current pneumogram - 8, which displays the breathing process in real time, coincides in scale with the reproduced pneumogram - 9, which was previously recorded and stored in electronic form as a pneumocode. The process of respiratory biocontrol consists in matching the current pneumogram with the reproduced pneumogram of the pneumatic code, which is achieved by arbitrary control of respiration.

Figure 4 presents one of the options for a computer game, the plot of which is determined by the coincidence of the current pneumogram (breathing at a given time), represented by a thin line - 10, with the pneumatic code represented in the form of a wide strip (tunnel) - 11. The current pneumogram coincides with the pneumatic code corresponds to a set of points, and going beyond the boundaries corresponds to a set of penalty points.

Utility Model Implementation

A device for recording and displaying respiratory cycles in the form of pneumograms and computer games works as follows. At the first stage, the user prepares pneumatic codes for positive emotions. For this, the device (headphones) is worn on the head (Fig. 1) so that the tube forming the air flow with the D-1 sensor (6) is located in close proximity to the nasal passage. Then, the software is launched on the computer to which the device is connected via the communication channel. The current pneumogram appears on the monitor computer, displayed in standard scale. The user independently or with the help of a psychologist forms a positive psycho-emotional state, during which (usually 2-5 minutes) this current pneumogram is recorded in the form of an electronic file (pneumocode). At the second stage, the device controls respiratory biofeedback.

The software allows simultaneously with the current pneumogram to display the recorded pneumogram in one standard scale (figure 3). Using software, you can record as many pneumograms as you can against the background of various positive psycho-emotional states. The user can select any recorded pneumogram so that looking at its display on the screen, adjust his current pneumogram under it. The combination of the current pneumogram with the recorded pneumogram (pneumocode), which are displayed in one standard scale, allows for respiratory biocontrol. Respiratory biocontrol can be carried out in the form of a computer game in which control is carried out using the current pneumogram, that is, the user's breath, and the game conditions are determined by the recorded pneumogram. Such computer games can be installed on any individual electronic device (personal computer, laptop, smartphone, tablet, etc.), which allows a person to conduct respiratory biocontrol sessions at any convenient time.
