Description

The invention relates to medicine, namely to traumatology and orthopedics.

Analogs A device for cryotherapy (Kuznetsov O.F., Styazhkina E.M., Gaziyan G.E. Patent 2074680, A61F / 00, application No. 95107427/14 dated 05/10/1995). Usage: the invention relates to medicine, namely to physiotherapy, therapeutic massage and, in particular, to the field of cryotherapy in the form of therapeutic external and cavity cryomassage. Essence: the device consists of an elastic sealed shell filled with a cooling agent in the form of ice and / or sodium chloride, or brine solution, or sea salt, or sea water with a concentration of from 0.8% to 3%, the elastic sealed shell can be made multi-section with a heat-insulating gasket, for intracavitary application of the device, an additional disposable shell is used, while the temperature of the cooling agent is minus 11 ° C - minus 25 ° C. Effect: increase the therapeutic effect during cryomassage. Cryomassage using the device is as follows. The device is taken from the side of the heat-insulating strip and at the beginning circular, spiral and rectilinear reciprocating movements in the massage area are carried out. For a deeper effect, short-term (3040 s) stable applications are used in combination with vibration and a varying degree of pressure on the area of the intended massage by the device. With cavity cryomassage, the application technique is mainly used.

Known hydrophilic gaskets used in galvanization (A method for the treatment of deforming arthrosis of the knee joint (Patent RU (11) 2263491 (13) C1 (51) 7 A61F 7/00, A61N 2/04, application No. 2004122311/14 of 07/19/2004). The area of the gaskets is from 120 to 200 cm sq., The specific heat is from 2 to 10 KJ. The gaskets were moistened with tap water, squeezed and placed for 2-4 hours in the refrigerator’s freezer at a temperature of -12 - -15 degrees. Two cryosets of the same size were placed locally in the area of the affected joint and was fixed with not tight bandaging. ladok at the skin surface in the early treatments ranged from 0 to 4 and the end of the procedure was raised to + 4 + 7 degrees.

The fan mode allows you to adjust the jet power and cooling capacity in a wider range, as well as to perform pulsed operation of the device depending on the selected procedure. After turning off the fan at the levels of the distribution-evaporation block due to heat influx from the environment as a result of forced convection of the ejected air, the evaporation of liquid nitrogen and its flow rate in the exhaust channel increase. The flow rate of the ejected air is controlled by the fan rotation speed set by the control unit and the mode control, and may vary depending on the readings of the level and temperature sensors installed on the device. In addition, the air, cooling, evaporates drops of the cryoagent, which eliminates the possibility of damage to the biological tissue by the liquid cryoagent. With smooth scanning movements at a distance of 2-4 cm from the nozzle of the working tip to a selected area of the surface of the body, it is treated with a stream of cryoagent.

It is known "device for local cooling" (RF Patent No. 2139015 by application No. 96107910/14 dated 04/22/1996; Author: Smirnov EP). It consists of a thermionic device with rigid heat exchangers in contact with its surfaces. A rigid heat exchanger via hoses is connected through a turnstile pump to an elastic heat exchanger (MINIFRIDGE), made in the form of two bandages connected in parallel, used for contact cooling of individual parts of the human body with a cooled liquid. A rigid heat exchanger through hoses is connected through a turnstile pump to a heat exchanger made in the form of several sections of bandages connected in parallel and in series and used for comfortable compensating heating of body parts, the cooling of which with cold air from an air conditioner is undesirable. The turnstile pump consists of a stator with elastic pipes fixed to it and a rotor made in the form of a lever with rollers fixed at its ends. The rotor is driven by a drive motor. Both rigid heat exchangers and elastic heat exchangers are hollow and each of the systems consisting of a heat exchanger connected by hoses through a turnstile pump with an elastic heat exchanger and a heat exchanger connected by hoses through a turnstile pump with an elastic heat exchanger is filled with a temperature transfer agent, in which quality water, alcohol or tasol may be used. The temperature transfer agent by means of a turnstile pump carries out temperature transfer from rigid heat exchangers and to the corresponding elastic heat exchangers. The heat exchangers and are equipped with temperature sensors and (for example, a resistance thermometer) connected to temperature regulators and (any known, for example, RT-049), through which the voltage from the power source is supplied to the thermionic device. The elastic heat exchangers in the form of bandages are provided for fastening to the human body with strips of soft fabric with Velcro. An elastic heat exchanger is placed in a heat-insulated chamber equipped with an inlet to reduce undesirable heat influx into the chamber and connected to an air conditioner (any known unified, with remote control at best, providing sufficient cooling capacity and creating the necessary temperature for an acceptable period of time). It is possible to use an air conditioner for working in a space outside a thermally insulated chamber, where an additional heat exchanger of the refrigerant circuit is located. The walls of the chamber are made of heat-insulating material: polyurethane foam, glass wool, cork, mineral wool, porous rubber, foam, etc. A device for local cooling works as follows. For local contact cooling action with the chilled liquid, a temperature controller is used for control, air conditioning through the natural environment - the air works to create comfortable conditions outside the fridge, where an additional heat exchanger of the refrigerant circuit is located (work "MINIMUM MODE"). Heat exchangers (minifridge) are put on a cooled area of the body and are attached with Velcro. The temperature is set to the desired temperature. The heat exchanger serves as a heat transfer radiator, and the fridge, if necessary, can be used, for example, for thermal procedures or as a clothes dryer, the accumulated heat from which can be released to the environment at any time using an air conditioner. When power is supplied to the thermionic electronic device, its surface with the heat exchanger attached to it begins to cool, and the other surface with the heat exchanger attached to it begins to heat up. When the rotor of the turnstile pump rotates, the temperature transfer agent is pumped, while the elastic heat exchanger begins to cool, acting cooling on the part of the body on which it is installed, and the elastic heat exchanger, when heated, gives off heat to the medium inside the cartridge. When the heat exchanger reaches the temperature set by the thermostat, the power to the thermionic device breaks, and the temperature decrease stops. But, as soon as the temperature of the heat exchanger rises above a predetermined temperature, the power is supplied to the thermionic electronic device again, thus maintaining an arbitrarily set temperature, without creating discomfort, since elastic heat exchangers do not cause pain and do not limit movements, but the temperature and humidity necessary for comfort supported by air conditioning. When air cooling is required and it is required to change the area of cooling effect, the device works "FRIGAGE MODE". The temperature of the warm heat exchanger is controlled using a thermostat and a temperature sensor in the same way as in a cold circuit. A person inside the fridge sets the required temperature using an air conditioner connected to the chamber, and selects the cooling zone, excluding the corresponding sections from the cooling by compensating heating with the most convenient sections of the warm heat exchanger, which are attached with Velcro. Compensatory heating is regulated, guided by a feeling of comfort or discomfort. Heat exchangers, if necessary, can be used for uncontrolled cooling, for example, soft drinks. Flexible heat exchangers can also be made of polymers by any known method so that communicating cavities are formed inside them along the entire inner surface adjacent to the body, through which the temperature transfer agent pumped by the pump flows. The use of a device for local cooling allows reliable and safe local cooling of any parts of the body in comfortable conditions. In this case, cooling of a particular part of the body is carried out at any given temperature and its value is changed during cooling. Criticism of analogues:

- Fastening or gluing with a patch of a solid-state device to any part of the body is inconvenient and creates discomfort.

- The disadvantage of the apparatus is its bulkiness and highly specialized, the inability to conduct local hypothermia.

- The inability to simultaneously cool segments on both sides.

- The device requires a power source.

Prototype: "Device for vibrocryomassage." (A positive decision on the grant of a patent for an invention 2009135211 (049613) dated 09/09/09. Author: A. Radzhabov). It consists of a housing connected to a handle, a latch and a ventilation grill. An engine with an axis is fixed inside the housing. An eccentric disc is mounted on the axis. Inside the latch is a removable cryoelement with gel. A capacitor is placed inside the handle. The capacitor is connected to the motor via wires. The capacitor is connected to the switch via wires. The switch is connected to the plug via wires. The vibration frequency is 50 Hz, the vibration amplitude is 1-2 mm. Weight - 0.5 kg. Temperature of removable cryoelement with gel (-10 degrees). Overall dimensions of the device - 130x190 mm; The diameter of the cryoelement with gel (5 pcs.) - 40 mm.

The “device for vibrocryomassage” is used as follows: Before starting work, the removable gel cryoelement, which is a cylindrical container half-filled with gel, is cooled in the freezer (The device is equipped with five similar removable gel cryoelements). Then put the removable cryoelement with the gel in the latch. Holding the device by the handle, insert the plug into the socket (220 V) and turn on the engine using the switch. The rotation of the eccentric creates vibration. The device is brought to the extremities and a cryoelement is applied.

The purpose of the invention: Relief of inflammation and pain. The goal was achieved with the help of: "Devices for local cryotherapy", consisting of a clamp (figure 1, position 1; figure 2, position 1; figure 3, position 1) with an axis (figure 2, position. 2) and the axis (figure 3, position 3). The axis (figure 2, position 2) has a limiter (figure 1, position 4; figure 2, position 4). The axis (figure 3, position 3) has a limiter (figure 1, position 5; figure 3, position 5). The axis (figure 2, position 2) is located inside the latch (figure 1, position 6; figure 2, position 6). The axis (figure 3, position 3) is located inside the latch (figure 1, position 7; figure 3, position 7). The latch (figure 1, item 6; figure 2, item 6) is attached to the cryoelement with a gel (figure 1, item 8; figure 2, item 8). The latch (figure 1, item 7; figure 3, item 7) is attached to the cryoelement with a gel (figure 1, item 9; figure 3, item 9). Diameter of cryoelements with gel - 40 mm; Temperature of cryoelements with gel (-10 ° C).

An example of a specific implementation: Patient R. (32 years old), was admitted to the trauma unit with complaints of pain in the left foot, alone, while trying to rely on a limb, edema that appeared after falling from a height of three meters, an hour before admission. As a result of the examination, the patient revealed an intraarticular, comminuted fracture of the left calcaneus, with the displacement of fragments and imposed skeletal traction over the calcaneus. To prevent further growth of edema, we used the proposed device. Before work, the device was placed in a freezer, where the gel was cooled to (-10 ° C). Then, the clamp was pulled apart (Fig. 1, Pos. 1; Fig. 2, Pos. 1; Fig. 3, Pos. 1) and applied to the foot, a cryoelement with gel (Fig. 1, Pos. 8; Fig. 2, pos.8) and - cryoelement with gel (Fig.1, pos.9; Fig.3, pos.9), on both sides, in the calcaneus, for 15 minutes. Then the device was placed in the freezer. The patient received six treatments every two hours, for two days. As a result, it was possible to prevent the growth of edema and to accelerate its reduction.

From the known designs intended for cryotherapy, this utility model differs in that:

- It has small dimensions, the diameter of cryoelements with gel allows you to act on limited symmetrical areas of the body;

- The small size of the device allows you to easily place it in the freezer;

- For the operation of the device there is no need for power sources, which increases the availability of the cryoapplicator and facilitates the work with it;

- The design, thanks to the clamp, is held on the cooled segment;

- The cryoapplicator cools limb segments from two sides, thereby increasing the efficiency of the procedure.

The technical result of the proposed utility model is local, bilateral cooling of the affected segment of the limb, a decrease in the intensity of the pain syndrome and edema.
