Description

Breathing simulator - 2

The utility model relates to the field of healthcare and can be used to train breathing in the mode of moderate hypoxia and hypercapnia during a user's sleep and / or a long treatment procedure.

The training effect of most breathing simulators is based on eliminating (decreasing) a chronic low oxygen content in the body or individual organs and tissues (hypoxia) by adapting the respiratory center, which leads to a decrease in the minute volume of breathing and, accordingly, a moderate increase in the concentration of carbon dioxide in the body (hypercapnia) at rest due to a periodic increase in the concentration of carbon dioxide in the inhaled air.

This, in turn, leads, according to a well-known pattern, to a rightward shift of the oxyhemoglobin dissociation curve with increasing carbon dioxide content in arterial blood, an increase in the degree of dissociation of oxyhemoglobin and, as a consequence, oxygen utilization by tissues in large quantities with the elimination (reduction) of chronic tissue hypoxia. (Agadzhanyan N.A. et al. The physiological role of carbon dioxide and human performance. - Publishing house of the Astrakhan State Medical Academy, 1995).

Most of the known breathing simulators, made in a stationary or portable version, contain a chamber for mixing atmospheric air with part of the exhaled air with a high concentration of carbon dioxide, see, for example:

- RU 2129885, A61M 16/00, 1999. 10 27, “Respiratory simulator V.F. Frolova ";

- RU 2266758, A61M 16/00, 2005.12.27, “Agranovsky breathing simulator”;

- RU 88272 U1, A61M 16/00, 2009.11.10., “Kolpikov breathing simulator”

- RU 171354 U1, A61M 16/00, 2017.05.29 "Respiratory simulator";

- RU 182008 U1, A61M 16/00, 2018.07.31.31, “Respiratory simulator healer”,

On such simulators, breathing in an active state is carried out unusually through a breathing tube and a mixing chamber and only by mouth.

On some simulators, breathing is carried out through a mask, but also through the mouth:

- RU 2256467 A61M 16/00, 07/20/2005 "Method for training the human respiratory system and device for its implementation."

Breathing on simulators involves a long workout and daily expenditure of free time for several months.

See, for example, the simulator - a physical training simulator "Complex" SAMOZDRAV "" (TU 9519-001-42529619-2001), implementing the "Method of increasing adaptive and compensatory capabilities of the body" (RU 2187341, A61M 16/00, 08/20/2002).

Known breathing simulators in which breathing in an active state is carried out naturally - by the nose, but also only through the mask:

- RU 158989 U1, А63В 23/18, 01/20/2016. "A device for interval hypocapnic-hypercapnic training of the human body."

- RU 2596886 A61M 16/00, 09/10/2016, "Respiratory simulator" (stationary),

- US 5647345 A61M 16/00, 07.15.1997. "Respiratory stimulator & methods of use" (Fig. 3 and Fig. 5 - portable options).

Also known is the "Sholin breathing simulator" (RU 2468833, А61М 16/00, 12/10/2012, which provides the possibility of protection during sleep of the face and head of the user from bites of flying blood-sucking insects with the simultaneous effect of training breathing in a dream.

The known breathing simulator, by the combination of essential features, is the closest analogue of the claimed simulator and is made in the form of a fabric-mating bag made of a dense fabric with a breathable filter, which together exclude contact of the user's head with flying blood-sucking insects. The filter is mounted on the bag near the location of the mouth region of the face of the user, and the mixing chamber is formed by a part of the bag’s interior between the face of the user and the filter.

The reasons that impede the achievement of the technical result indicated below, when using the known simulator, include the relative complexity of its design

The task to which the claimed utility model is directed is to simplify its design.

The technical result obtained by the implementation of the utility model is to simplify the design of the breathing simulator

The specified technical result in the implementation of the utility model is achieved by the fact that in the inventive breathing simulator comprising a bag made of fabric with the possibility of pairing with the user's head, in contrast to the known simulator, the bag is equipped with a stiffener in the form of an elastic plate mounted along the entire length of the pocket oriented along the middle line of the front side of the bag and combined with its bottom, while the fabric of the bag is made breathable.

The bag of the simulator can be made of terry or waffle fabric, and the pocket can be made closed, and the bottom of the bag is made quadrangular with three axisymmetric generators.

In FIG. 1 shows the front side of the simulator, FIG. 2 - a simulator prepared for storage or transportation (side view), in FIG. 3 - position of the user's head while using the simulator.

The breathing simulator (Fig. 1, 2) is made using sewing technology of breathable fabric in the form of a bag 1 with a bottom 2 and an extended pocket 3 with an elastic plate 4. The pocket 3 is oriented along the midline of the front side 1 _{1 of the} bag 1 from it the bottom 2 to the location of the mixing chamber 5, formed when using the simulator with a part of the internal space of the bag 1 between its front side 1 ₁ and the rotonous region 6 of the user's face.

Opposite the bottom 2 of the bag 1, the inlet 3 _{1 of the} pocket 3 is equipped with a button 3 ₂ to limit the longitudinal movement of the elastic plate 4. The bottom 2 of the bag 1 is preferably quadrangular with three axisymmetric generators 2 _1-3 .

The breathing simulator works as follows.

The user, before going to bed or during a lengthy treatment procedure, when putting on the simulator bag 1 (Fig. 3) on the head towards the middle of the bottom 2 ₂ until the forehead of the user is stationary in contact with the elastic plate 4, which bends with its opposite bottom 2, the end 4 ₁ moves the front surface section bag 1 ₁ over the rotonous region of the face of the user 6, and, thus, in the internal cavity of the bag 1 creates the space of the mixing chamber 5 with the stiffener 4.

When the user exhales, part of the exhaled air with an increased concentration of carbon dioxide fills the mixing chamber 5. With a subsequent inhalation, atmospheric air enters the mixing chamber 5 through the breathable fabric of the bag 1, mixes with the air of the previous exhalation, and is used for the next inhalation with the increased concentration of carbon dioxide.

The prototype simulator was made of wafer fabric in the form of a bag 1 with a height of 50 and a width of 40 cm (before washing) with a quadrangular bottom 2 formed by three axisymmetric generators 2 _1-3 . In a pocket 3 sewn to the middle line of the front side of the bag 30 cm long from the bottom of the bag 1 and 4 cm wide, an elastic plate 4 was placed, measuring 280 × 38 × 1 mm, made of half a PVC profile with an angle of 40 × 40 × 1, GOST 30673- 2013 PVC profiles for window and door blocks.

If necessary, to maintain the hygienic state of the simulator after removing from the pocket 3 of the plate 4, the simulator can be washed. After washing, the tissue of the simulator undergoes about 10% shrinkage.

To increase the convenience of storage and transportation, the simulator can be given a compact shape (Fig. 2).
