Description

The utility model relates to the field of training and training of underwater swimmers (divers) in apparatuses with an open breathing cycle, in particular, to devices and accessories for training exercises and instruction in scuba diving without water [А63В 69/10].

To ensure the comfort and safety of underwater dives in devices with an open breathing cycle, the diver must master the special techniques of slow, but without delay, breathing, as well as controlling buoyancy during the dive. Currently, training in these basic skills is carried out during practical dives in the individual diving equipment with an instructor, first in closed and then in open water. Practice shows that for a stable mastery of these skills a novice diver then needs a lot of practical dives, each of which is associated with certain risks of stress, hypothermia, barotrauma, decompression diseases associated with diving. In fact, most divers make a series of 10-20 real dives once or twice a year during the holidays. At the same time, it takes a lot of time and money to master the breathing technique and the skill to control buoyancy.

A known method of learning to swim (application RU 2005122710), including adapting students to the aquatic environment, practicing coordinated movements of arms and legs, setting breathing coordinated with movements of arms and legs, correcting the performance of coordinated movements and breathing to achieve automatism of all movements and actions, is different the fact that the training is carried out in three stages, while at the first stage they conduct preliminary training on the main symbols of scuba diving, on the main problems, on the main actions and movements under water, after which they carry out a test scuba dive to a depth of five meters, then at the second stage they carry out a series of preparatory exercises without diving to develop skills in working with a mask, working with a buoyancy compensator, and adjusting neutral buoyancy at the bottom, on working with a belt, on working with a breathing regulator and an octopus, on assembling and disassembling a scuba gear, according to the rules for picking a cargo belt, after which at the third stage they practice diving skills, surfacing me and getting out of the water.

This teaching principle applies to the PADI standard. Training in breathing and buoyancy control skills is done in water. This is a significant disadvantage of the method.

The proposed technical solution allows them to be carried out of water in a safe and comfortable environment without the use of expensive personal gear and equipment.

Known biocontrolled game simulator (patent RU 2349256), comprising a display, heart rate sensor and control software, characterized in that it further comprises an amplifier for a heart rate sensor connected in series with the heart rate sensor, connected in parallel with the circuit "heart rate sensor - amplifier for heart rate sensor", sensor breathing and in series with it an amplifier for a breathing sensor, and the control software includes a digital signal controller, a control microcontroller, configured to implementations of data processing algorithms, control of game plots, processing signals from the function key block, displaying information on the display and evaluating the success and effectiveness of the game, external FLASH data memory, control keys, the first analog input of the signal controller connected to the amplifier output for the heart rate sensor, and the second analog input of the signal controller is connected to the output of the amplifier for the respiratory sensor, the output of the signal controller is connected to the first input of the control microcontroller, the first output for which it is connected with the third input of the digital signal controller, the second input and the second output of the control microcontroller are connected respectively with the first input and the first output of the external FLASH memory, the third input and the third output of the control microcontroller are connected respectively with the first input and the first output of the display, the fourth input and the fourth output is connected respectively to the first input and the first output of the external USB transceiver, and the fifth input of the control microcontroller is connected to the control keys.

A method of teaching a patient to control the physiological function in a situation of virtual competitive stress is based on the use of a multiparameter control signal in the form of a pulse rate, respiration rate and the magnitude of their ratios “T” by changing the color of the light indicator, and at the optimal value of the calculated value “T” to achieve the set in the training task, the indicator color is green, with a slight deviation - yellow, with a more significant deviation - red.

In other words, the trainee learns to control his functional state without mastering the breathing technique and the technique of his own buoyancy, which directly depends on the volume of respiratory gas in the lungs.

The closest solution is the Training Method (patent RU 2364436), which consists in the fact that during the learning movement this movement is digitized, compared with the digitized model of the reference movement and, if the learner made a deviation in the volume of any body parts controlled in the movement being learned, from the reference movement, he receives tactile signals that correct the movement of the corresponding parts of the body in volume in real time.

The difference between this method and the claimed utility model is that not a separate movement is subject to training in the proposed device, but a complex integrated skill, the trainee receives not a tactile signal, but a biocontrolled visual image for correcting his respiratory movements. He learns not to copy the reference breathing curve, but to learn its type, creatively applying it to control his own buoyancy.

The technical result of the utility model is the provision of the possibility of individual training of breathing techniques and the ability to control buoyancy in diving in safe and comfortable conditions at any convenient time by conducting not real, but virtual diving with the help of a biocontrolled interactive hardware-software simulator connected to a personal computer.

The specified technical result is achieved due to the fact that the interactive hardware and software simulator of breathing techniques and the ability to control their own buoyancy in diving, containing a breathing sensor, a computer with a display, characterized in that the hardware of the simulator consists of a half mask with an inhalation-expiration tube, made with the possibility of fixing on the trainee’s face, on which an electronic measuring unit is installed, consisting of an electronic respiration sensor with a signal amplifier and a digital controller, and The electronic measuring unit is connected to a personal computer. The electronic measuring unit can be connected to a personal computer via a USB port or wirelessly.

Utility Model Implementation

A utility model can be implemented as follows. The hardware of the simulator (see Figure 1) is a half mask (2) secured by an elastic strap on the face of the trainee (1) with an inhalation-expiration tube (3), on which an electronic measuring unit (4) is mounted. The power supply of the unit and the removal of the useful signal can be carried out, for example, via a cable (7) connected to a computer (5).

The software part of the simulator allows the trainer to interactively set the initial and change individual current parameters of virtual diving, set and copy the reference profile of the respiratory cycle, and also biofeedback the vertical movement of the diver’s model (8) (see Figure 3).

The breathing technique and the individual skill of controlling buoyancy in safe mode are trained out of the water by biocontrolling a diver’s computer model and copying the reference breathing profile during a virtual scuba dive simulated using a biocontrolled interactive hardware-software simulator connected to a personal computer. The user trains the breathing technique, trying to breathe so that the curve of his own breathing cycles (9) displayed on the computer display (see Figure 3) coincides with the reference (10) set in advance. The trainee makes the initial adjustment of buoyancy by correctly selecting the ballast weight of the diver’s computer model (8) and quickly controlling the air volume in the model’s buoyancy compensators during virtual diving using the corresponding buttons on the computer keyboard. The training diver makes fine tuning and control of buoyancy by changing the degree of filling of his own lungs during continuous breathing, thereby biofilling the vertical movement of the diver model (8) in the underwater scene on the computer display. The hardware of the simulator is a half mask (2) secured by an elastic strap on the face of the training person with an inhalation-expiration tube (3), on which an electronic measuring unit (EIB) is mounted (4). The EIB consists of an electronic respiratory sensor with an appropriate signal amplifier and a digital controller. The power supply of the EIB and the removal of the useful signal is carried out via a cable (7) connected to the computer (6) via the USB port, or the EIB is independently powered (4), and communication with the computer is carried out wirelessly.

The software part of the simulator is installed on any computer at the disposal of the trainer with the operating system installed on it.

The software part of the simulator allows you to:

- receive and process the useful signal of the EIB;

- Perform individual calibration of the respiratory sensor;

- interactively set the initial conditions of a virtual training dive (size and thickness of the wetsuit, type of balloon, gas supply, water density, weight of ballast, speed and direction of flow);

- training a person by changing the pace and depth of breathing according to the graphs displayed on the computer display, adjust the curve of his own breathing cycles to a predetermined reference;

- for the trainer, by changing the degree of filling of his own lungs, to biofeedback the vertical movement of the moving model of the diver displayed on the computer display in the corresponding underwater scene during the virtual underwater dive;

- display on the computer display the essential current parameters of the virtual dive (curve of breathing cycles, depth, course, horizontal and vertical speeds, current time, time limit of no decompression diving, minute flow rate of respiratory gas, remaining gas supply);

- interactively change individual current parameters of virtual immersion (horizontal speed, direction of movement, pitch, air volume in buoyancy compensators);

- to signal a violation of safe modes (unacceptable breath holding, excessive ascent rate, exhaustion of the time limit) during a virtual dive.

Work on the simulator is carried out by connecting the cable of the simulator's hardware to the USB port of a working computer on which the simulator software is pre-installed. Putting on the face a half mask (2) of the simulator (see Figure 1), the training person (1) launches the simulator program and, working in dialogue mode with the "Initial immersion conditions" window (see Figure 2), according to the breathing schedule, makes an individual calibration (adjustment) of the respiratory sensor built into the half mask, selects the correct weight of the ballast, selects the reference profile of the breathing cycles. Having finished the settings and setting the initial conditions for immersion, the trainee proceeds to develop (restore) and improve the breathing technique and the skill to control buoyancy. In this case, an underwater scene with the figure of a diver (8) is displayed on the computer display (see Figure 3). Using the buttons to change the volume of the buoyancy compensators, as well as changing the pace and depth of breathing, the degree of filling of his own lungs during breathing, the trainee controls the diver’s model on the computer display, achieving its correct location and combining the curve of his own breathing cycles (9) with the reference (10) ) In real diving, it is these skills that allow the diver to avoid the risk of barotrauma and control their own buoyancy during the dive. Thus, the trainee develops the diver’s skills and the ability to develop, restore and improve individual breathing and buoyancy control skills at any convenient time outside the water in a safe and comfortable environment without real diving, without the use of expensive personal equipment and equipment, without risks stress, hypothermia, barotrauma, decompression diseases associated with being under water.
