A well-known stand-alone wearable temperature, pulse and respiration monitor containing a small instrument unit in the form of two parts: measuring and transceiving, sensors connecting cables, connectors made on the flat side of the measuring and transceiving parts for their electrical and mechanical connection, chest belt with shoulder straps (see RF patent for industrial design No. 53227, MKPO 24-01, publ. September 16, 2003).

The monitor is not suitable for use in the swimming process.

A known dialogue system for measuring physiological parameters such as heart rate, blood pressure, etc., the user in motion, containing one or more acceleration sensors or forces to be mounted on the user's body, monitor, wireless transmitter, such as infrared, acoustic or radio transmitter , to transmit a weighted signal from the sensor to the monitor, made with the possibility of interactive video display, recording and showing the level of physiological personal parameters over time (see US patent No. 5524637, MP A61 B5 / 103, A61 B5 / 22, publ. 11.06.1996 city).

It is difficult to adapt the system to analyze swimmer’s breathing parameters.

Portable spirometer is applicable only in stationary conditions.

A known system of non-contact continuous recording of the respiratory rate of a person in the process of his activity, including an accelerometer sensor made with the possibility of fastening with a clip on the pocket of his underwear in the projection of the heart, a power source and a storage device made with the possibility of mounting on underwear and / or clothes, this memory device through a signal transmission system is connected to a computer for processing signals (see RF patent for utility model No. 73772, IPC A61 5/02, publ. 10.06. 2008).

The known system is difficult to apply for dynamic control of breathing in swimming. It provides control of one breathing parameter - the respiratory rate, which is not enough for a comprehensive analysis of the swimmer's respiratory system.

Closest to the claimed technical solution is a portable telemetry system for recording the parameters of an athlete’s breathing in real time, including a respiratory sensing element installed in a face mask connected through a signal processing unit to a transmitting device, means for attaching a signal processing unit and a transmitting device, a receiving device, connected to a computer for processing the received signals (see patent WO No. 9853732, A61 B5 / 00; A61 B5 / 024, publ. 03.12.98, prototype).

The known system has only ground use.

Thus, all known systems for controlling the physiological parameters of respiration are not adapted to the swimming process.

Known commercially available breathing tubes for a swimmer, comprising a body with a silicone mouthpiece and a fastening means in the form of a plastic forehead with an annular holder and strap (see fig / 1a - "Front tube SCN-83S" company Akvilon, http: //www.czar. rn / subcats.php; Fig. 16 - “S-665 - Finis Center Mount Snorkel” by FINIS, Inc .; “Mad Wave Respiration Tube, China, http://www.swimshop.ru/images/snorkelmv.jpg ; “TUSA Platina Hyperdry SP-110 Tube”, http://www.paradive.ru/shop/catalog/details/1449).

The breathing tubes have two main parts: a mouthpiece and a tube body. The mouthpiece has an anatomical shape and is made of soft silicone, which without difficulty allows you to hold the tube in your mouth. A distinctive feature of tubes for high-speed swimming in flippers is their placement in the center of the forehead, and not on the side of the head, which allows you to freely fold and extend your arms behind your head. The breathing tube is held onto the swimmer’s head with a rubber strap from the forehead.

Known breathing tube for a swimmer, containing a body without a mouthpiece and means of fastening it in the form of a strap with a forehead connected to an annular holder (Fig.1-c depicts a tube at http://www.krasnikita.com/Archive/articles/fins.htm )

Athletes use breathing tubes with an internal radius of not more than 48 cm, made of plastic pipe with an internal diameter of at least 20 mm. To avoid gum rubbing due to tube vibration at high speeds, mouthpieces by swimmers are generally not used, and the edge of the tube is held in the mouth by the teeth.

Tubes for high-speed underwater sports are placed along the nose line for better streamlining, are diverse in shape and require the use of a special mask or glasses. The tube is designed to provide breathing while swimming on the surface of the water without having to raise its head for inspiration. Breathing through the tube is comfortable and safe when swimming near the surface. These known tubes have a low weight.

Closest to the claimed technical solution is a breathing tube for speed swimming, made with frontal fastening on the swimmer’s forehead with a strap having a forehead with an annular holder (see US application No. 2007199565, IPC B63C11 / 16, published on 08.30.2007, prototype) .

All of the above known breathing tubes do not provide the ability to register the parameters of the swimmer’s breathing, which reduces the efficiency of their operation.

The technical result of a real-time integrated system for recording external respiration parameters is to create a simple breathing control system that makes it easy to record respiration parameters during swimming and in terrestrial conditions, providing training efficiency.

The technical result of a useful model of a breathing tube in ensuring the convenience and safety of recording respiration parameters during swimming and increasing the efficiency of training and operation of the breathing tube.

1-a, b, c show samples of commercially available sports breathing tubes for swimmers designed for high-speed swimming. Figure 2 shows a turbine flow sensor. Figure 3 shows a diagram of a portable integrated telemetric system for recording the parameters of the athlete's breathing in real time. Figure 4 shows another variant of the specified system. Figure 5 shows a sports breathing tube without a mouthpiece with a turbine flow sensor. Figure 6 shows a breathing tube with a mouthpiece and a turbine flow sensor mounted on the swimmer's head when swimming.

A real-time portable telemetric registration system for recording breathing parameters includes (Fig. 3) a swimmer’s breathing tube 1 with a respiratory sensing element (Fig. 2) in its cavity, made in the form of a digital air flow sensor 2, connected through a signal processing unit 3 to a transmitting device 4. In a simplified embodiment, the system has a receiver 5 connected to a computer 6 for processing the received signals. In another embodiment, the system (Fig. 4) may further have a capnometer 7 and an oximeter 8 connected to the signal processing unit 3.

The breathing tube 1 (Fig. 5,6) of the swimmer has means of attachment to the head in the form of a forehead 9 with an annular holder 10 made of elastic material and a strap 11. In the forehead 9, an annular holder 10 fixes the respiratory tube 1 in the center of the swimmer's face (along the nose between eyes). The strap 11 is made with the possibility of adjusting its tension on the head of the swimmer. The strap 11 is also used as a means of fastening the signal processing unit 3 and the transmitting device 4 (Fig.6).

The sensitive element can be made, for example, in the form of a removable digital turbine sensor 2 for air flow (FIG. 2), comprising a cylindrical housing 12 made of plastic with an impeller 13 mounted on its axis. The digital turbine sensor 2 for air flow can be disposable or reusable depending on the design of its fastening in the breathing tube 1. It is preferable to use transitional tight sleeves, (not shown in FIG.), which make it possible to install the housing 12 of the turbine flow sensor 2 in zduha sectional sports breathing tube 1 (fig.5,6). The housing 12 is preferably made of a transparent material for visibility of the state of the impeller 13. The collapsible connection of the specified sensor 2 with the breathing tube 1 makes it possible to replace it if necessary. For the proposed system, removable digital turbine sensors 2 air flows are suitable, including unidirectional, characterized by high measurement accuracy and used, for example, in a MicroGP handheld microspirometer (General Practician) from Micro Medical (Great Britain). The sensor is lightweight and insensitive to changes in humidity and temperature. This will allow you to not calibrate it for a long time. The air flow sensor 2 is sterilized if necessary. To do this, it is disconnected from the breathing tube 1 and placed either in warm soapy water or in a cold sterilization solution for 15 minutes (without alcohol or chlorides), and then washed in water.

The breathing tube 1 is configured to front central (frontal) mounts on the swimmer’s head for high-speed surface sports swimming. In this case, it can be performed without a mouthpiece (Fig. 5) with an end 14 made with the possibility of installation in the swimmer’s mouth when swimming, or with a mouthpiece 15 (Fig. 6) of a straight form, as in the tubes in Fig. 1-a, in , and is attached to the swimmer’s forehead by a strap 11. Side tubes with a mask attachment are possible (not shown in FIG.).

The length of the breathing tube 1 and its diameter can be different (a longer one is filled with water and spray, but a larger volume of water must be blown out when diving; a large diameter provides less resistance to air flow, but increases the volume of water for blowing). Thus, the large diameter of the breathing tube 1 facilitates breathing, but creates difficulties in clearing water. A longer length reduces the likelihood of water entering the tube, but increases dead air space (part of the volume that remains in the tube and lungs with a high carbon dioxide content). This led to the standardization of the size of the breathing tubes: length - 350-450 mm, inner diameter 18-25 mm. In the lower or middle part of the breathing tube 1 can be placed special valves that release water and air and water from it, but not letting them back in, which greatly facilitates the force required to blow it (not shown in Fig.).

The signal processing unit 3 from the sensing element is a microprocessor with a low-voltage direct current source (battery). The connecting wires, including from the air flow sensor 2, the signal processing unit 3, and the transmitting device 4 are made with waterproof shells and housings with a corrosion-resistant coating. Their total weight is not more than 150 g.

The strap 11 is configured to fasten the signal processing unit 3 and the transmitting device 4. In other possible embodiments of the invention, swimming goggles 16 and / or a swimmer’s cap (not shown in FIG.) Can also be used as means for attaching the indicated unit 3 and the transmitting devices 4.

Before breath control, the cylindrical plastic casing 12 of the disposable turbine sensor 2 of the air flow with the impeller 13 is secured in the context of the breathing tube 1 by, for example, transitional tight sleeves (not shown in Fig.).

The signal processing unit 3 and the transmitting device 4 are fixed on the strap 11 (Fig.6). To secure them, the strap 11 may have a special tight pocket with a fastener and / or a special clip.

Thus, during the registration of the integral signal from the air flow sensor 2, the swimmer is not limited in movement, and therefore, continuous recording can be carried out both at rest, and in the process of the swimmer performing his sports activity in full.

In the process of swimming in training, the integral signal of air vibrations in the swimmer’s breathing tube 1 is recorded, caused by air flows during inspiration, resulting in corresponding changes in the rotational speed of the impeller 13 of the digital air flow sensor 2, which are recorded and processed by the signal processing unit 3. The rotational speed of the impeller 13 is proportional to the flow rate, and the number of revolutions to the volume of incoming air. The processing results are transmitted for analysis from the transmitting device 4 to the receiving device 5 via telemetric communication channels or are recorded on a flash card and can be evaluated in real time.

After the registration of signals by the receiving device 5, the integral signal is copied to the computer 6, and the signal from the microprocessor of the signal processing unit 3 is removed, which makes it possible to prepare the system for subsequent recording. The integrated signal stored in the computer 6 can be subjected to rapid analysis using specialized software. Computer 6 uses a mathematical formula to calculate the physiological parameters of a swimmer’s breathing based on his movement in water. The results can be printed on a printer. Computer 6 allows you to accumulate and store and compare the results over time.

An analysis of respiration parameters, including respiratory rate, inspiratory to expiratory ratio, pulmonary ventilation per unit time, inspiratory and expiratory flow rates will allow an objective, real-time assessment of the dynamics of the respiratory system and its functional reserves, which makes it possible to carry out controlled correction of training to maintaining maximum swimmer performance. Analysis of training records makes it possible to increase the effectiveness of the training process.

The inclusion of a capnometer 7 in the system will allow you to objectively establish hypo and hyperventilation of respiratory disorders by capnography. The inclusion of an oximeter 8 in the system will determine the oxygen content in the air.

Thus, using this system, the claimed purpose is realized with the achievement of the above technical result.

The creation of the proposed swimmer’s system and breathing tube does not require large material costs, since all the structural components, including removable flow sensors, software are produced by the industry as part of portable mini spirometers. In this case, the turbine air flow sensor can be integrated into any known sports breathing tube (Fig. 1) with a front mount on the head. In this case, the swimmer works with the usual breathing tube for him without special training and unnecessary manipulations during installation with the ability to determine the parameters of external respiration in the pool water and the gym.

The inventive device is simple, safe to use, allows a swimming athlete to freely perform rowing movements and determine the parameters of pulmonary ventilation in the conditions of direct performance of exercises in the aquatic environment, which will lead to reliable forecasts of sports results, the ability to determine an athlete’s preparedness for competitions and their degree of performance.
