Description

 The invention relates to medicine and medical equipment and can be used to treat cardiovascular diseases.

 A known method of auxiliary blood circulation of the lower extremities by applying a tourniquet and multi-section cuffs to them, filling them with air and creating a pressure wave [1].

 However, the disadvantage of this method is the low efficiency of arterial and venous blood flow due to the deposition of blood in the peripheral regions of the limb.

 A device for increasing blood circulation, containing multi-section cuffs with a source of compressed air [1].

 However, this device for the movement of a pressure wave in the distal direction does not provide an increase in arterial blood flow and does not exclude the deposition of blood in the peripheral parts of the limb.

 The purpose of the invention is the increase in arterial and venous blood flow by eliminating the deposition of blood in the peripheral regions of the limb when the pressure wave moves in the distal direction.

 This goal is achieved by the fact that, according to the method of auxiliary blood circulation and a device for its implementation, a non-stretch fabric stocking is put directly on the limb under the cuffs, then compressed air under a pressure of 130-150 mm Hg is successively supplied to each section of the cuff, starting from the proximal, from top to bottom. Art. until the last section is filled, and when filling each subsequent section, the pressure in the previous section is dumped to 10 - 0 mm Hg, then the pressure in the last section is dumped to 50 - 40 mm Hg, then the process is repeated in the reverse order, accordingly, from the distal to the proximal limb, from bottom to top, with a duration of a cycle of increasing pressure of each section from top to bottom 5 to 20 s, with a wave of pressure from top to bottom 5 to 20 s, and with a wave of pressure from bottom to top, the cycle time is 20 - 60 s, session duration 40 - 70 min 1 time per Shade daily for 4 - 6 weeks.

 In FIG. 1 shows a general diagram of a device for auxiliary circulation; in FIG. 2 is a diagram of a fabric stocking with fasteners in profile and in full view; in FIG. 3 - cyclogram of the device.

 The device consists of sections of pneumatic cuffs 1 - 6, which creates pneumomechanical pressure on the lower limb 17, pneumocompression apparatus 13, consisting of an electronic control unit 12, an electric motor 15 and pneumocompressor 16, which supplies compressed air to the section of pneumatic cuffs 1 - 6. There are non-stretch fabric covers 7 , 8, one of which 7 is worn directly on the lower limb, and the second 8 - on the outer part of the cuffs, being a power cover. Pneumatic cuffs 1 - 6, consisting of sections 1 - 6, are stretched, located around the lower limb. The sections are operated by a control unit 9, consisting of electro-pneumatic valves 10 and electrical wiring 11 connected to the pneumatic compression apparatus 13. The pneumatic compression apparatus 13 is connected to the control unit for the operation of sections 9 and pneumatic cuff sections 1 - 6 using an air supply hose 14.

 Non-stretch fabric stocking is presented in figure 2 (a - profile; b - full face). The fabric stocking 1 is equipped with a tape with loops 2, a tightening cord 3 and a zipper 4.

 The operation of the device is as follows.

 On a limb 17 put on a fabric stocking 8, adjust it using lacing 3 and zipper 4 (figure 2). Cuffs 1 - 6 are connected to a compressed air source — pneumocompression apparatus 13 and electrical wiring 11. Then the pneumocompression apparatus 13 is turned on. Compressed air from compressor 16 is supplied to electro-pneumatic valves 10, which, according to the program of the electro-pneumatic valves 12 control unit, supply compressed air to section 1 - 6 pneumatic cuffs.

 Filling sections of the pneumatic cuff with compressed air occurs sequentially, starting with the proximal section, i.e. closest to the body. Compressed air is supplied to the proximal sections 6 to 5 at a pressure of 130 to 150 mm Hg. within 5 - 20 s, after which simultaneously release the air pressure of 10 - 0 mm Hg in the previous section 6 and fill the subsequent section 4 with compressed air to 130 - 150 mm Hg The next cycle is repeated until the distal section 1, venting the air pressure in each previous section to 10 - 0 mm Hg, and held for a predetermined time of 5 - 20 s. Pressure relief in the last distal section 1 is carried out up to 50 - 40 mm Hg. Subsequently, the process is repeated in reverse order.

 Example 1. Patient E., 53 years old, was admitted to the hospital with a diagnosis of obliterating endarteritis of the lower extremities II tbsp. Complaints of pain in the legs, especially the right, when walking. No more than 300 - 400 m can pass without pain. These phenomena have been noted over the past 5 years.

 Objectively: the skin of the legs is pale, cold, venous pattern is not pronounced. Palpation - pulsation on the femoral artery is preserved, on the popliteal and arteries of the foot is sharply reduced.

 The patient underwent a course of pneumomassage. A non-stretch fabric stocking was put directly under the cuffs under the cuffs, then compressed air under a pressure of 130 mm Hg was successively supplied to each cuff, starting from the proximal, from top to bottom. until the last section is filled, with each subsequent filling, the pressure in the previous one was released to 10 mmHg. Art. then pressure relief was carried out in the last section up to 50 mm Hg.

 Further, the process was repeated in the reverse order, from the distal to the proximal limb, from bottom to top, with a duration of a cycle of increasing pressure of each section from top to bottom for 5 s, with a pressure wave from top to bottom for 5 s, and for a wave of pressure from bottom to top, the cycle duration was 20 with a duration session 40 min once a day, daily for 4 weeks.

 After the auxiliary blood circulation was carried out according to the indicated method, warming of the skin of the legs was noted, the pain practically disappeared.

 During thermography, before the start of treatment, there was no image of the big toe of the right foot ("thermal amputation"), on the left - the image of the remaining parts of the foot and lower leg is represented by brown, orange and red colors, indicating a decrease in infrared radiation.

 After the procedure, a thermographic image of the big toe of the right foot appeared, the image of the remaining departments is represented by a spectrum of red, violet and green tones, only certain parts of the foot retain brown-yellow colors.

 Thermography data indicate an increase in the temperature of the skin of the legs and feet and an improvement in blood flow after the procedure.

 Example 2. Patient K., 46 years old, was admitted to the hospital with a diagnosis of obliterating endarteritis of the lower extremities, II tbsp. Complaints of pain to the legs, especially the right, when walking. No more than 500 m can pass without pain. These phenomena have been noted over the past 7 years.

 Objectively: the skin of the legs is pale, cold, venous pattern is not pronounced. Palpation - pulsation on the femoral artery is preserved, on the popliteal and arteries of the foot is sharply reduced.

 The patient underwent a course of pneumomassage. Under the cuffs, a non-stretching fabric stocking was put on directly to the limb, then compressed air under a pressure of 150 mmHg was successively supplied to each cuff, starting from the proximal, from top to bottom. until the last section is filled, and during the filling of each subsequent section, the pressure in the previous one was released to 0 mm Hg, after which the pressure in the last section was reduced to 40 mm Hg.

 Further, the process was repeated in the reverse order, from the distal to the proximal limb, from bottom to top, with a cycle of increasing pressure of each section from top to bottom for 20 s, with a pressure wave from top to bottom for 5 s, and for a wave of pressure from bottom to top, the cycle duration was 60 with a duration Session 70 min once a day, daily for 6 weeks.

 After the auxiliary circulation was carried out according to the indicated method, warming of the skin of the legs was noted, the pains practically disappeared.

 During thermography, before the start of treatment, there was no image of the big toe of the right foot ("thermal amputation"), on the left - the image of the remaining parts of the foot and lower leg is represented by brown, orange and red colors, indicating a decrease in infrared radiation.

 After the procedure, a thermographic image of the big toe of the right foot appeared, the image of the remaining departments is represented by a spectrum of red, violet and green tones, only certain parts of the foot retain brown-yellow colors.

 The use of longitudinal segmental rheography before and after the procedure, an increase in the amplitude of the main wave, the rheographic index and the electrical conductivity index also showed changes indicating an improvement in the blood filling of the lower leg.

 Thus, the proposed method of pneumatic massage of the extremities helps to improve blood flow in the lower extremities with obliterating endarteritis.
