(57) Abstract:

Usage: for the treatment of patients with burns and optimal humidity, removal of the fluid from different phone inventive preliminary drying air, followed by evaporation of the liquid from the air and from the body of the patient using the device, which consists of a Cabinet with the chamber filled with granules in the form of balls and a closed sheet, distribution chamber, the pump chamber of the two compartments, where the evaporator and the heater, condenser, compressor, fan and a pressure sensor. 3 C.p. f-crystals, 3 ill.

The invention relates to medical equipment, namely, beds, designed primarily for placement of patients with burns, and can be used in various medical institutions.

Known bed to accommodate oboe negative containing chamber with pellets, sheets of wire fabric distribution chamber with a porous partition, the system of air power in the form of filter, pump, heater, cooling units, control equipment with the remote control.

A disadvantage of the known beds is that it is not provided by pre-drying air, evaporation of the liquid and optimum humidity in the room.

This goal is achieved by a method and device for removing moisture and fluids from one or more bodies, including a layer of granules that absorb liquid is exposed to air with controlled temperature with subsequent formation of a fluidized bed of granules, in the form of balls placed in the chamber beds, equipped with a sheet of wire fabric distribution chamber with a porous partition, and the system of air power in the form of filter, pump, heater, cooling units, control equipment with the remote control, enter the preliminary drying air supplied into the chamber with pellets, which pseudogout with subsequent evaporation of the fluid through the introduction of a system of air supply air chamber separated by permeable partition into two compartments, and evaporating means in the form of a compressor and condenser with fan and heater.

In Fig.1 shows a bed, a General view of Fig.2 section a-a in Fig.1; Fig.3 a schematic cross-section of a more General application of the device.

The device shown in the drawings, has the air is, fine cloth "Policon" with a permeability of 50 μm. Sheet 1 closes the chamber 2, which is filled with a material in the form of beads, for example, granules of calcium glass type "Natron", has an antiseptic effect.

The bottom with the camera 2 is reported the distribution chamber 3, which leaves highway 4 air supply. The partition between the air chamber 2 and the distribution chamber 3 is formed by a porous wall through which air in the chamber 2 is carried out as evenly so that under the action of the incoming air fluidization occurs filler under the underlying surface 1. In the result, the patient will be in the fluidized bed, which repeats, which results in a uniform support of the patient.

Therefore, should be chosen such temperature fluidized bed, which would be the most comfortable for the patient. The implementation of such measures exclude the formation of bedsores.

Used for the fluidization air, which flows through the channel 4, is preheated in a special conditioning device, which is indicated in General position 5. This device is l 7, which is located in the air chamber 8, to which is connected at the same time bringing the nozzle 4 and the supply line 9. Ambient air, indicated by arrow R1served in the supply pipe 9 through the air pump 10 and is drawn from the area surrounding the device through the opening 11 in the lower part of the Cabinet.

The operation of the air pump 10 is controlled by the pressure sensor 15 so that constant pressure fluidization regardless of the body weight of the patient.

Evaporative means includes a part of the cooling system, which also includes a compressor 12 and a condenser 13. The capacitor 13 is equipped with a fan 14 for heat dissipation. The compressor 12 regulates the flow of refrigerant, such as freon, the connection lines in the direction of the arrow P2through evaporative means 7.

In the chamber 8 in the compartment 8' under the evaporator 7, a heating coil 16, which is installed in the connecting line between the compressor 12 and the condenser 13.

The air entering the channel 9 from the pump 10 may be subjected to preliminary heating of the electric heating element 17.

The principle deist, the pump 10 and the channel 9 if necessary, it may be subjected to preliminary heating of the heating element 17 before entering the air chamber 8. In the cooling there is air drying: dried thus air enters pseudovariety layer 2 through the channel 4 and the distribution volume 3 and may be returned to the environment through the sheet 1. Relative humidity and temperature are regulated so that in therapeutic relationship he was most acceptable to the patient. When removing moisture and liquids from the air through the chamber 8 on the side of the evaporator can be formed drip liquid condensate which is collected in the lower compartment 8. In this compartment there is a heating element 16, a part of the circulation of freon, which after cooling of the air in the air chamber 8 is heated freon in the compressor 12, after which the heated refrigerant is returned to the heating element 16, where the evaporation flowing condensate. Further, the refrigerant is condensed in the condenser 13. The proposed schematic has the additional advantage that all taken from the patient's body fluid, which is returned in the distribution allows the removal of such excess fluid due to evaporation. Moist air is withdrawn from the evaporator compartment 8 into the environment outside the device in question, which contributes additional humidification of the ambient air compared to the dried process air 5 used for the liquefied layer 2.

For effective treatment, the temperature of the fluidized bed may be 26aboutWith which is maintained constant when the temperature of 20-35aboutC and relative humidity of 85% of the pressure in the system vozduhoplavaniya maintained at 420 mm water. Art. regardless of the surrounding air pressure and weight of the patient. The volume flow of air is preferably 52,9 m3whereby the relative humidity of the ambient air may vary in the range of 35-85% Maximum relative humidity of fluidized air is 72%

As granular absorbent filler used calcium maintenanced glass type "Natron", which, with the above parameters has 1.5 times higher viscosity than water. Under this condition, the immersion of the patient in the liquefied layer is of the order of 10 cm, which provides the necessary "floating" treatment.

Air is introduced into the distribution chamber 20 through line 23 under the action of a fan or blower 24. If necessary, the line 23 may be equipped with a dehumidifier 25 of any type. This dehumidifier can be performed in the example discussed with reference to Fig.2.

In contrast to the considered example in this case there is no need to evaporation flowing down the liquid in the heating element 16.

In the air-distributing chamber 20, the layer of granulated filler 21 pseudogiants above the partition 19, resulting in a drained items easily ignored in the layer, can linger in the layer within the specified time depending on the feed rate R1and then deleted in the drained condition. Due to the turbulence of the fluidized bed wet balls filler 21 continuously adelaidean is not limited to the examples presented implementation, for example, to provide the desired evaporation heating element 16 can be made electric. However, there is a possibility of using any other source of heat. The heating element 16 can be placed in the Assembly capacity, which is separated from the air chamber 8, which may communicate with the distribution area 3 and pseudoviruses camera 2.
