A ventilator includes a support made in the form of a frame 1 with hard wheels. On the outer side of the frame 1 on the side surfaces is made of four spaced pairs of oppositely and symmetrically relative to the longitudinal axis of the tide 2 with hole. On top of the frame 1 is placed a hard bed of solid rollers with headrest and stopper. On top of the frame 1 is mounted actuator. It consists of four inserted smooth plot hole tides voltage is alausa 4, four elastic elements, such as twisted cylindrical or conical springs, put on a smooth stretch of each rail 4, rib cuff 6, placed between the rails 4 consisting of an elastic sheet 7 made in the form of a rectangle, for example, of rubber, medium hardness, with the bushing 8 at the corners, solid strap 9 which is made of solid material, for example of stainless steel, attached to the middle of the sheet 7, the two cords 10, attached at one end to the opposite lateral sides of the bracket 11 with eyelets, sleeves 12, placed the sleeves 12 on the threaded section of the guides 4, desktop authority placed over the chest and sleeve 6 made of the axis 14, the ends are sealed in the bearing lugs of the bracket 11 with the disk 15 with two diametrically spaced openings, means 16 for effects on breast cuff fixed to the disc 15 can move relative to axis 14 having a U-shaped groove 17, which is made on the middle and on the side surfaces of one slotted oblong slit "a", having a length defined by the expression L=2·D, where L is the length of the slit, D is the diameter of the disk 15. The drive of the working body consists of an electric motor 18, gear 19 with the gearbox, clutch 20, which connects the motor and the reducer, fixed Nekrosiene 11, circuit 21, covering the sprocket 22 mounted on the output shaft of the reduction gear 19, the sprocket 23 mounted on the end of axle 14, a tensioning device 24 associated with the bracket 11, a roller in contact with the chain 21, the two screws 25, the connecting means 16 to influence the cuff 6 with the disc 15. The nut 26 is fixed guides 4 in the holes in the ebb 2 and sleeves 12 of the bracket 11 on the rails. The scale 27, programmirovanie in millimeters, attached to one of the rails 4. The width of the gaps "a" allows you to move them in the axis 14 and screws 25.

The ventilator operates as follows.

Bed 3 with the patient "g" is slid on the frame 1 so that the chest was located under the flap 9 of the sheet 7 breast cuff 6. Establish the required eccentricity of the means 16 for impacts on chest sleeve 6 relative to the axis 14. To do this, loosen the screws 25 and move the tool 16 in the desired direction to the desired value of eccentricity relative to the axis 14. Tightening the nuts of the screws 25, the tool 16 is tightly pressed against the disk 15. The magnitude of the eccentricity is determined experimentally depending on the elasticity of the thorax of the patient and possibly the respiratory tract (inhalation - exhalation). Attach the chest cuff 6 patient "g" by body coverage with a subsequent connection of the ends of the cord 10. The working position is Lana relative to the chest of the patient "g", if necessary, you can install by translational movement of the bracket 11. To do this, loosen the tightness of the upper (lower) nut 26 and move the bracket 11 in the desired direction (up or down) to the required value. This sleeve 12 to move with the slide on the threaded section of the guide 4. Then the position of the bracket 11 is fixed by tightening the nuts 26. Switching circuit set the rotation of the armature of motor 18, the clutch 20, the gear 19, the sprocket 22, the circuit 21, the sprocket 23 and through the axis 14 and the disk 15 of the tool 16. When rotating means 16 acts on the bar 9 of the sheet 7 of the cuff 6, which descends and presses on the chest of the patient "g". Due to the telescopic connection of the sleeve 8 slide on the smooth section of the guides 4 without transverse vibrations compress the elastic elements 5. Thanks to the thorax of the patient "g" is deformed (compressed), and then work on compression and the lungs of a patient "g". Exhalation occurs exhaust air from the body. Upon further rotation of the tool 16 comes with strap 9 (dead point), the elastic elements 5 open and return thoracic cuff 6 to its original position, i.e. thoracic cuff moves up. Freed from the burden chest straightens. When this occurs, the expansion of the lungs, i.e. there is a breath of fresh air. So of origin Taiwan is the CIO to restore natural breathing process. Tidal volume is determined by the magnitude of chest compression. Changing the distance "e" of the movement means 16 with respect to axis 14 can be adjusted tidal volume from 0 to the desired limit. When the respiratory rate does not change as time double stroke breast cuff 6 (compression - expansion of the lungs of the patient is determined by the time of revolution of the disk 15 axis 14, i.e. the means 16. Adjusting the tidal volume is performed by moving the screws 25 oblong slits "and" tool 16 with respect to axis 14.

The breathing frequency is determined by the number of double strokes of the chest cuff 6 per minute, which in turn is determined by the frequency of rotation of the disk 15 axis 14 in a minute. Regulation of frequency of rotation (and hence the frequency of breathing) is gearbox gear 19 or the replacement of one of the sprockets 23 or 22 on larger diameter or smaller. On a scale 27 determine the depth of inhalation and exhalation.

The implementation of a support frame on the hard wheels as a dense bed of solid rollers with the possibility of extension, improves conditions of artificial respiration to the patient and his input on the site of restoration of breathing, and the stopper 28 secures the bed on the frame.

Performing breast cuff material of medium hardness provides reliable fixation of the patient on a bed, and a hard strap improves samocha is the result of the patient. The implementation of the working body in the form of means for influencing the chest cuff and the axis of the disk simplifies the design, and thus reduces the cost of the device.

Performing a U-shaped groove reduces the mass of the means for influencing the chest cuff, and side slits having a length of L=2·D. provide for the regulation of the depth of breathing of the patient within wide limits.

This device can be used to restore the patient's breath in stationary and non-stationary conditions. Has a simple design and can be manufactured in small workshops. Reduces the complexity of maintenance and repair.
