RU2103974C1 - Method for controlling pressure in pneumatic massage cuff sections - Google Patents

Abstract

FIELD: medicine. SUBSTANCE: method involves creating physiologically adequate pressure magnitudes in different sections. To do it, pressure is changed corresponding to patient respiration rhythm. Double traveling wave of changes in pressure on two adjacent sections moves by one section from peripheral part towards the center so that not more than two adjacent sections are under pressure. Cuff section size is selected not to exceed 10 cm. EFFECT: enhanced accuracy of anthropometric measurements. 4 cl, 2 dwg

Description

 The invention relates to physiotherapy, and more specifically to means for pneumomassage, and can be used to compensate for blood flow disorders in astronauts, as a prophylactic and therapeutic agent for diseases associated with chronic venous insufficiency (thrombophlebitis, varicose veins), as well as one of the components of the treatment of cerebral palsy and relaxation, treatment of injuries and selective muscle gain in athletes, ballet dancers, etc.

 The existing tool for pneumatic massage / 1 / contains a cuff with inflatable chambers, a source of compressed air, as well as an electronic program control unit, which includes a pulse generator with a counter, a unit for setting the pulse duration, a matrix storage device, a unit for specifying the number of cameras to be included, a unit for setting a sequence pulses (pneumocompression mode), a unit for changing the duration of pulses depending on the volume of individual chambers (sections) of the cuff, a unit for pneumatic valves. The device / 1 / allows you to change the duration of the pneumatic pulses for individual groups of inflatable sections depending on their volume to ensure uniform compression of the limb, regardless of the volume of individual sections and the individual characteristics of the patient.

 Also known is a pressure control system in the sections of the pneumatic massage / 2 /, into which means are added that regulate the pressure according to the rate of its change, and pressure regulation in individual sections is provided. The technical result of the system / 2 /, adopted as a prototype, is to increase the effectiveness of treatment (venous disturbances are excluded), by creating pressure that is physiological in various sections of the cuff and transferring these values with sufficient accuracy and speed.

 These methods of pneumomassage do not provide coordination of changes in pressure in the cuffs with venous return of blood due to the patient’s breathing. All modes of these devices do not take into account the phases of the rhythms of venous return of blood and lymph flow of a particular patient. Inadequate blood flow pneumocompression can stretch the veins and side effects in such cases reduce the effectiveness of treatment.

 The technical task to be solved is the elimination of side effects, increasing the effectiveness and stability of the therapeutic effect by restoring the natural regulation of blood flow and lymph flow.

 The proposed method of controlling the pressure in the sections of the cuff for pneumatic massage is to create in various sections of the cuff pressure adequate physiological. A feature of the method is that the change in pressure is carried out in the rhythm of the patient’s breathing. In this case, a double traveling wave of pressure change on two adjacent sections of the cuff moves one section from the periphery to the center so that no more than two adjacent sections are simultaneously under pressure, and the size of the cuff section is chosen no more than 10 cm, which corresponds to the distance between the valves in the veins .

 The method can be carried out, for example, using the known device / 1 /, in which the dual traveling wave mode is set and the temporary section switching mode is set corresponding to the measured respiratory rhythm of the patient. The use of an additional breathing sensor allows the pressure increase of the next section of the cuff only at the time of inspiration of the patient. At the same time, only two adjacent sections remain under pressure, and in the previous section (the third from the inflated), the pressure is relieved. Thus, with each new inhalation of the patient, the pressure wave moves from the periphery to the center and, reaching the last section, again moves along the leg (arm) from the periphery to the center. Coordination with the phases of breathing of the moments of inflation and depressurization in the cuff sections excludes pressure against the flow of blood in the veins, improves hemodynamics.

 Rheographic studies and registration of capillary blood flow using a laser Doppler method with the Coral apparatus confirmed the advantages of the biofeedback regimen during pneumatic massage in patients with chronic venous insufficiency, which is indirect evidence of the advisability of using the proposed method of pneumatic massage of astronauts (astronauts) for the prevention and treatment of limb hemodynamics as a result space flights, especially of long duration.
