The working (pressing) surface of the trunk 2 is conventionally the chest 2.1. The mannequin trunk 2, when folded, forms a space 5 of the trunk 2, formed by folding the blank of the mannequin trunk 2 over the perforated surfaces 2.3, so that the perforated surfaces 2.3 constitute the sides of the mannequin trunk 2. In the space 5 of the mannequin trunk 2 is located a simulated cardiopulmonary resuscitation system composed of two opposed sets of inner layers: a set 3.1 of upper inner layers which is an element pressed by the user and a set 3.2 of lower inner layers as a pressed and stiffening the mannequin trunk 2 element; shock-absorbing layer 6; a spring element 7, which comprises a set of three springs and a replaceable bladder 8 simulating the lungs. The folded trunk 2 of the training mannequin 1 is stiffened at the bottom with an additional outer layer 9 connected to the lower surface 2B of the trunk 2 with an adhesive layer (not shown in the drawing). The additional layer 9 has the shape of a human trunk with the cervical section 10 and the head 4. The layers of the set 3.2 of lower inner layers conventionally have the shape of a human trunk with the cervical section 10 and the head The head 4 of the mannequin constitutes 45% of the length of the entire of the mannequin trunk 2 in the longitudinal dimension. The head 4 of the mannequin is composed of layers constituting a movable set 4A of layers, equipped with an outer layer 4.3 made of pressboard and an immovable set 4B of layers joined to each other by adhesive layers. The outer layer 4.3 additionally includes a movable connecting element 4.1 conventionally located on the section of the top of the head 4, constituting part of a head 4 blank, which enables the movable set 4A of layers of the head 4 to be moved. The movable set 4A of layers is provided with a first mouth inlet opening 4.2. The inner layer 4.4 of the movable set 4A of layers, made of cardboard, constitutes the stiffening part of the movable set 4A of layers. The layers of the movable set 4A are permanently joined by adhesive layers. The immovable set 4B of layers is made of three cardboard layers non-detachably joined with adhesive layers, which are then joined to the head 4 blanks constituting elements of the blanks of the layers of the inner lower layer set 3.2 of the additional layer 9, and all the immovable layers (4B) of the head 4 are provided with distal inlet opening 4.2.1 of the mouth. The distal inlet opening 4.2.1 of the mouth is set back from the first inlet opening 4.2 of the mouth for proper guiding of the feed tube 8.2 of the bladder 8 simulating the lungs and for proper execution of the inspiratory action.
The set 3.1 of upper inner layers consists of five layers having a triangular blank. The layers of the upper set 3.1 consist of a 1 cm thick cardboard layer, a 1 mm thick pressboard layer and three 1 cm thick cardboard layers, joined to each other and to the inner upper surface 2A2 by means of adhesive layers (not shown in the drawing).
The set 3.2 of lower inner layers consists of two layers of cardboard, each 1 cm thick, joined to each other with adhesive layers and to an external stabilizing frame 1 cm thick 3.2.1, in which the flexible layer 6 is placed.

The device is placed on the bottom (lowest) layer of the inner set 3.1 of the upper layers which is sensitive to vibrations of the mannequin trunk 2 during its use.
The bladder 8 simulating the lungs is made of recyclable plastic, i.e. polyvinyl chloride, and it consists of an air chamber 8.1 and a supply conduit 8.2 ending with the upper part 8.3 provided with an air inlet opening 8.4. In the longitudinal section, the air chamber 8.1 has the shape of an irregular pentagon, with a base having width s = 12 cm, sides extending from the base at a right angle a and height di = 9 cm and total height d = 10.5 cm. A supply conduit 8.2 of length d2 =10 cm equipped with a collar 8.2.1 of height ds = 3.5 cm is ended with an upper part 8.3 with an outline similar to the canopy of the letter "T", which has a base of width S2 = 28.5 cm, and the central part of the canopy has a semicircular projection 8.3.1, wherein the projection 8.3.1 covers the outer part of the edge of the canopy, the corners of which, conventionally from the outside of the canopy, are semicircular, wherein the radius R determining the arc of these semicircles is R = 1 cm. The supply conduit 8.2 is equipped with an additional outlet opening 8.2.2 with a diameter of 1 mm, protecting against excessive inflation of the air chamber 8.1, located in the upper part of the supply conduit 8.2, near the collar 8.2.1. The inlet opening 8.4 is located in the area of the central part of the protrusion 8.3.1, the protrusion 8.3.1 is rolled outwards and arranged around the inlet opening 4.2 of the mouth so that the person performing rescue breathing after opening the airway can easily force air inside. The solution allows to perform the exercise in a hygienic way because the user will only touch the disposable film with his mouth. The entire bladder 8 simulating the lungs can be replaced after the exercise, maintaining epidemiological safety. The bladder 8 simulating the lungs is placed externally in the cutout 9.1 of the additional outer layer 9 of the trunk 2 towards the distal inlet opening 4.2.1 of the mouth and the first inlet opening 4.2 of the mouth, extending through this inlet opening 4.2 of the mouth and beyond the first inlet opening of the mouth 4.2 to the outside. The training mannequin 1 according to the invention allows resuscitation activities in the following way.
The chest 2.1 of the mannequin trunk 2 is subjected to compression to a depth of 5 - 6 cm at a rate of 100 - 120 / min, which is achieved by pressing in place of the approximate centre of the chest, located halfway between the clavicle line and the line of rib arches in the middle line of the trunk, i.e. in the location of the upper set 3.1 of the cardiopulmonary resuscitation system, where the pressure of the user of the training mannequin 1 on the chest 2.1 causes compression of the upper set 3.1 of the inner layer and deflection of the springs of the spring element 7 to the surface of the elastic layer 6, and then the chest 2.1 of the trunk immediately returns to its starting position (re compression phenomenon). Then, the user tilts the movable set of layers 4A of the head 4 blank and through the first inlet opening 4.2 of the mouth introduces air cyclically (2 breaths) into the bladder 8 simulating the lungs, running through the distal inlet opening 4.2.1 of the mouth, whereby the bladder 8 simulating the lungs fills with air (what simulates the rising of the rescued person's chest) and then the user renews pressure on the chest 2.1. A device with an application for measuring the quality of the exercise performed during chest 2.1 compressions which is placed in the cut-out 2.4. responds to movement of the chest 2.1. Data from sensors are collected at the maximum frequency available in a given device, not less than 50Hz. The data goes to the motion detection and analysis module. As the device is tilted, the readings change. For small vibrations, the sensor response is small. Too strong compression causes the chest 2.1 of the mannequin trunk 2 to hit the shock-absorbing layer 6 and causes a vibration deviation, which generates an additional signal indicating incorrect compression. Pressing too lightly will result in the signal not being counted. The number of positively collected signals over time is presented to the user. Data flowing directly from the sensors are pre-processed to eliminate artifacts and measurement noise. The steps are repeated until the correct reading is obtained.
The present invention is not limited to the above-described embodiment. Various modifications and developments are possible within the scope of the attached patent claims, without departing from the essence of the invention. Reference list:
