Description

The utility model relates to medicine, namely to physiotherapy, and can be used to enhance regional blood flow, lymphatic drainage and increase the outflow of blood from venous vessels. Possible applications - for postoperative and post-traumatic rehabilitation, in professional sports and cosmetology for individual patient use, including for mobile use.

It is known that auxiliary blood circulation can be organized using hardware massage devices (pressotherapy). For mobile use, such devices must be portable and lightweight.

Known commercially available portable device for pressure therapy [Air Massager Nissei AM-7. URL:] with the possibility of individual use and constant hidden wearing due to its light weight and small dimensions.

The device contains a single-chamber cuff with a width of 50 mm with the possibility of adjusting the diameter, a pump, a control unit for compression and operating modes, a control panel and a power source in the form of a battery, all of which are integrated into one unit.

The advantages of this device are:

- the possibility of use with constant wear, during long trips to eliminate stagnation of blood and lymph, during operations for auxiliary circulation;

- adjusting the diameter of the cuff allows you to use it for people of different constitution.

The disadvantages of this solution are:

- small width of the cuff, which allows massage only limited areas of the limb;

- low reliability and low resource of the device due to the use of mechanical parts - compressor and inflatable cuff;

- since there is only one cuff, only one pressure therapy regimen is possible - massage;

- insufficient functionality - physiotherapeutic effect is made only in the form of pressure therapy.

Closest to the claimed utility model is a pressotherapy device - an individual massager for patients with chronic heart failure [Klypin D.N., Nechaeva G.I., Druk I.V. Individual massager for patients with chronic heart failure. // Patent for the floor. Maud. No. 113146 U1 of the Russian Federation, IPC A61H 1/00] (prototype).

The known device includes several cuffs with the possibility of adjusting the diameter, a control unit for operating modes, a control panel and a power source in the form of a battery, a voltage converter, a voltage adjustment unit coming from a voltage converter, and the cuffs are made identical, separate and made of electroactive film polymers (EAP).

The advantages of this device are:

- the possibility of use with constant wear, during long trips to eliminate stagnation of blood and lymph, during operations for auxiliary circulation;

- separate execution of cuffs allows using them for massage of several limbs and organization of auxiliary blood circulation during operations on the limbs;

- several modes of pressotherapy - massage, lymphatic drainage, intermittent and intermittent compression with a given rate of rise and fall of exposure in each cuff.

The disadvantage of this solution is the limited functionality, since the physiotherapeutic effect is performed only in the form of pressure therapy.

The task of creating a utility model is to expand the functionality of the device for auxiliary circulation and enhance the therapeutic effect through the use of an additional type of physiotherapeutic effect - electrical stimulation.

It is known that electrical stimulation (ES) is a therapeutic physiotherapeutic method of influencing the nervous and muscle tissue, which is used to achieve myoneurostimulating, vasoactive and other therapeutic effects. [Bogolyubov V.M., Ponomarenko G.N. General physiotherapy. - M: LLC "SLL", 2003 - S.90]. The use of ES is indicated for paresis, paralysis and muscle atrophy.

This object is achieved in that the device for auxiliary circulation, including at least two cuffs with the ability to adjust the diameter, the control unit for operating modes, the control panel and the power source in the form of a battery, a voltage converter, a voltage adjustment unit, supplied from the voltage converter moreover, the cuffs are made identical, separate and made of a film of electroactive polymers, according to the claimed technical solution, an additional device but it contains an electro-stimulating generator and two electrodes, the input of the electro-stimulating generator being connected to the output of the operating mode control unit, the first output of the electro-stimulating generator being connected to the first electrode located on one cuff, the second output of the electro-stimulating generator is connected to the second electrode located on another cuff.

The essence of the utility model is illustrated by the functional diagram of the device shown in figure 1.

The device contains: cuffs M1 and M2, voltage adjustment nodes U1 and U2, a supply voltage converter 1, an operating mode control unit 2, a control panel 3, a power supply 4, an electro-stimulating effect generator 5, electrodes E1 and E2.

The voltage adjustment nodes U1 and U2, the supply voltage converter 1, the operating mode control unit 2, the control panel 3, the power supply 4 and the electro-stimulating effect generator 5 are integrated with the cuff M1 in the housing 6. The cuffs M1 and M2 contain several layers of EAP film 7. The electrode E1 is placed on the inside of the cuff M1, the electrode E2 is placed on the inside of the cuff M2.

An increase in the functionality of the device compared to the prototype is achieved through the use of an electrostimulating effect generator 5 together with electrodes E1 and E2.

The voltage converter 1 serves to obtain the desired voltage on the plates of the EAP film 7 from the voltage of the power supply 4. The voltage adjustment nodes U1 and U2 serve to change the voltage on the plates of the EAP film 7 of the cuffs M1 and M2. The voltage is changed by the operating mode control unit 2 in accordance with the operating mode selected by the user on the control panel 3. When the voltage on the plates of the EAP film 7 of the cuffs M1 and M2 changes, the length of the EAP film 7 changes and, as a result, the pressure on the limb . The power source 4, made in the form of a standard battery, serves to power all nodes of the device. The generator of electrical stimulating effect 5 is used to obtain the voltage of electrical stimulation on the electrodes E1 and E2. The parameters of the electro-stimulating effect are changed by the operating mode control unit 2 in accordance with the operating mode selected by the user on the control panel 3.

A device for assisted circulation works as follows. First, a cuff M1 is put on a limb with an integrated electronic part and an electrode E1 connected to the first output of the generator of electro-stimulating effect 5. Then, the desired number of independent cuffs M2 with an electrode E2 is put on a limb. Each cuff is tightly fixed to the limbs with any type of fastener. An EAP film of 7 cuffs M2 is connected to the outputs of the voltage adjustment unit U2, the electrode E2 is connected to the second output of the generator of electro-stimulating effect 5. The user selects the necessary modes of pressure and electrical stimulation on the control panel 3. In accordance with the selected mode, the control unit for operating modes 2 using voltage adjustment nodes U1, U 2 begins to change the voltage on the plates of the EAP film 7 in the cuffs M1 and M2, thereby controlling the pressure of each cuff on the limb, and by controlling the generator lektrostimuliruyuschego impact electrosrimulating 5 creates an impact on the electrodes E1 and E2. The mode of operation determines the amplitude and duration of pressure exposure, the duration of a pause, the rate of change of pressure in each cuff, as well as the amplitude, frequency and time parameters of the electrical stimulating effect.

Cuffs M1 and M2, depending on the desired therapeutic effect, can be located on one limb or on different limbs.

The positive effect in the proposed utility model is based on a combination of constructive and circuitry solutions that allows to increase the functionality of the device for auxiliary circulation and enhance the therapeutic effect of its use.
