- the invention relates in particular to the field of hydrotherapy for therapeutic, curative or preventive purposes, or for the purpose of training, recovery and playfulness of human or animal subjects. These baths are particularly involved in the resolution of circulatory disorders and trophic disorders encountered in rheumatology or accidental trauma or sports.
- the invention relates to a device for heat treatment of a person or animal, called "patient” in the remainder of this text, by immersion in baths of liquids of different temperatures, namely a bath at high temperature, or hot bath, and a bath at a lower temperature, or cold bath.
- the device allows a great freedom of movement to the patient, in particular to pass from one bath to another, but also to reduce the exchange of material and the heat exchange taking place between the two liquids of different temperatures in contact with each other. the other.
- Such a device is used in particular, but not exclusively, in the context of hydrotherapy, defined as all treatments using the properties of water, when a patient is brought to be immersed alternately and at least partially in several baths of different temperatures according to the well-known model of the "Scottish shower” or "Scottish bath".

- the device according to the invention is based on the well-known principle of the "Scottish shower” or “Scottish bath” consisting in exposing the body of a patient to hot water and cold water alternatively.
- the passage from hot water to cold water or vice versa is carried out in a brutal way without any transition of temperature, that is to say without passing through an average temperature between the temperature of the cold water and that of the hot water.
- the blood vessels and more generally the blood present in the immersed areas of the body of the patient, are subjected to the pressure of the water, greater than surface air pressure, the value of which depends in particular on the depth, that is, the height of the water column.
- the pressure of the water makes it possible, among other things, to promote the circulation of the venous return.
- Hydrotherapeutic treatments are generally carried out using two separate static basins, which do not communicate with each other, a first basin containing hot water, and a second basin containing cold water.
- the patient is immersed partially or totally in the first pool for a period of typically of the order of minutes depending on the protocol of treatment adapted to the patient, then it leaves the first pool before immersing in the second pool for a duration of same order of magnitude. This time elapsed, the patient leaves the second pelvis before immersing himself again in the first pelvis. The patient continues to switch from one pelvis to another a number of times depending on the treatment followed.
- the document RU2161945 describes a bath-type physiotherapy apparatus in which the patient can bathe.
- the apparatus comprises a support connected to a waterproof removable module, said module being able to be positioned across the bath, allowing a separation of said bath into two sections.

- the channels 2.1, 2.2 form a liquid circulation loop, in which the patient can move during the treatment, being partially or totally immersed.
- the first and second channels are each delimited by an inner wall 3 and an outer wall 4.
- the bath zones are separated from each other by a central wall 4.1 common to said bathing areas, and resulting from the meeting of the outer walls 4 of the two bath areas 2.1, 2.2.
- the inner walls 3 facing the central wall 4.1 are advantageously convex so as to guide the currents Fi, F2de liquid toward said inner walls 3, as far as possible from said central wall 4.1.
- the central wall 4.1 comprises an opening 5 allowing the two bath zones 2.1, 2.2 to communicate with each other and the two liquids to be in contact with each other, so that when the patient is in the first bath zone 2.1 for example, he can pass in the second bath zone 2.2 by borrowing the opening 5 provided in the central wall 4.1.
- the patient remains immersed in the first liquid and then in the second liquid and in contact with said first and said second liquid.
- the immersed parts of the body of the patient are then subjected to the pressure of the first and the second liquid, the value of which is greater than the atmospheric pressure and depends on the depth of the liquid, and this throughout the duration of the treatment.
- the immersed parts of the patient's body remain under the same liquid pressure (the same hydraulic pressure in the case of water) and benefit from the effects of this pressure invariance.
- the dotted circles in Figures 1 and 3 indicate different positions of the patient during treatment.
- an exchange zone consisting of an interface 6 between the two liquids, symbolized by a rectangle in Figures 1, 3, and 5.
- the interface has not been shown in Figures 2 and 4 to allow better readability.
- the difference in temperature between the two liquids results in a heat transfer at the interface (first and second principles of thermodynamics), from the liquid of higher temperature Ti, to the lower temperature liquid T2.
- the heat exchanged between the two liquids is even more important than the difference in temperature between the two liquids is great.
- the thickness of the interface denoted e in FIG. 1, is negligible since it corresponds to the thickness of the macroscopically visible line or boundary between the two liquids.
- the interface is voluntarily represented with a large thickness.
- the device according to the invention further comprises a liquid injection system 10 located in the vicinity of the opening 5.
- the injection system as shown 1 to 3 comprises a first injection head 1 1 provided with liquid injection nozzles 12.1, 12.2, of which at least a first injection nozzle 12.1 of the first liquid at the temperature Ti opens on the first zone of bath 2.1, and at least a second injection nozzle 12.2 of the second liquid at the temperature T2 opens on the second bath zone 2.2.
- the first injection nozzle 12.1 and the second injection nozzle 12.2 are located on either side of the opening 5 and are directed so that the injection flow F and Fb are located in the vicinity of the opening 5. This is a direction, that is to say, a path followed by the flow F and Fb, not a moving direction or orientation.
- the flows F a and Fb of the injection nozzles 12.1, 12.2 of the first injection head 11 can be convergent as shown in FIG. 5, that is, they are oriented from so as to approach each other, or divergent as shown in Figures 1 to 4, that is to say that they are oriented so as to move away from each other.
- the flows F a , Fb can be oriented in the same direction (co-current) as shown in Figures 1, 2, 3, and 5, or in the opposite direction (countercurrent) as shown in FIG. figure 4.
- the flow Fa, Fb injection nozzles 12.1, 12.2 of the first injection head 1 1 contribute to circulate the liquids in their respective bath zone according to the currents F1, F2.
- Said currents F1, F2 induced in particular by the injection flows F a and Fb are distinct, that is to say that they do not mix and do not merge.
- the exchange of material and the heat exchange between the two liquids are minimized and only occur at the interface 6, of negligible thickness.
- each of the streams F1, F2 retains a similar physical and / or chemical composition, and in particular a similar temperature, at any point of their respective channel 2.1, 2.2.
- the patient who borrows the opening 5 then instantly passes from the first temperature liquid T1 to the second temperature liquid T2 via the interface 6, or in the opposite direction.
- the effects of the thermal shock are thus maximized since the patient's body does not have time to regulate its temperature, in particular at the submerged portions to be treated.
- the effects of the treatment are thus improved.
- the injection system 10 may comprise a second injection head 14 in addition to the first injection head 1 January.
- the second injection head 14 is provided with one or more injection nozzles 15.1, 15.2 of liquid, of which at least a first injection nozzle 15.1 of a first liquid at the temperature Ti of flow F c opens on the first bath zone 2.1, and at least a second injection nozzle 15.2 of a second liquid at the temperature T2 flow Fd leads to the second bath zone 2.2.
- the first head 1 1 and the second head 14 are located at the ends 7 of the opening 5, and define said opening.
- the second head 14 may in particular allow, depending on the direction and orientation of the flow F c , Fd, to avoid the backflow of liquids to the opening 5 and can improve the results obtained with the first head January 1.
- the injection system 10 may generate one or more flows F a , Fb, and one or more flux F c , Fd.
- the flow F c, Fd can be directed and oriented toward the opening, so that said flux F c, Fd face the flow F a, Fb (flow oriented in the opposite direction or against the grain) as shown in Figure 4.
- the flows F a , Fb, F c , and Fd can be convergent, divergent, or parallel.
- the speed of currents F1, F2 is preferably between 0.1 km / h (km / h) and 15 km / h, and preferably between 1 km / h and 7 km / h, and more preferably preferred between 2 km / h and 5 km / h, the value of 5 km / h being a reference to the speed of movement of a horse in a step.
- the flows F a , Fb, Fc, and Fd have a dual function, in that they make it possible on the one hand to ensure that the currents F1, F2 do not mix, and on the other hand to keep the temperature of each of the first and second liquids constant and identical at every point of their respective channel 2.1, 2.2.
- the injection nozzles 12.1, 12.2, 15.1, 15.2 of the first injection head 1 1 and / or the second injection head 14 are arranged in one or more vertical or horizontal rows.
- all or part of the injection nozzles 12.1, 12.2 or injection nozzles 15.1, 15.2 can be merged and therefore constitute a single injection assembly.
- the first injection head 1 1 of the injection system 10 is advantageously flared, so that its width, noted I in Figure 1, increases as it approaches the opening 5. This flared shape contributes, with the convex shape of the inner walls 3 of the first and second bath areas 2.1, 2.2, to diverge the currents Fi, F2 of liquids arriving at the opening 5, guiding them to the inner walls 3, as far as possible of the aperture 5 and the interface 6.
- the combination of the first injection head 1 1 of flared shape and the inner walls 3 of convex shape allows to impose liquid streams F1, F2 a preferred direction of circulation, and thus contributes with the flows of injection F a , Fb of the injection head 1 1, to contain the exchange of material and the heat exchange between the first liquid at the temperature T1 and the second liquid at the temperature T2 at the interface 6.
- a thermal shock whose intensity is a function of the temperature difference of the liquids of the two zones, which allows optimal treatment of said patient.
- the first injection head 1 1 comprises at least a first injection nozzle 12.1 of a flow F which opens on the first bath zone 2.1
- the second injection head 14 comprises at least a second injection nozzle 15.2 Fb flow opening on the second bath 2.2 area, so that the flow F and Fb face each other.
- the fluxes F a and Fb are then parallel and oriented in the opposite direction.
- several injection nozzles may be arranged along the surfaces of the injection heads opposite the opening. Currents F1, F2 are also, and therefore, oriented in opposite directions (countercurrent).
- the first injection head 1 1 further comprises at least a first secondary injection nozzle 13.1 of a flow Fc and at least a second secondary injection nozzle 13.2 of a flow Fd leading respectively to bath zones 2.1 and 2.2.
- the second injection head 14 comprises at least a first secondary injection nozzle 16.1 of a flow F c and at least a second secondary injection nozzle 16.2 of a flow Fd opening respectively to the zones bath 2.1 and 2.2.
- the flow Fc and Fd contribute with the fluxes F a and Fb to the maintenance of the currents Fi and F2 which are distinct from one another, and to the invariance of the temperatures of each of the bath zones 2.1 and 2.2.
- the heat treatment device 1 further comprises at least one inlet 8 and at least one outlet 9 intended to be taken by the patient in order to penetrate inside said treatment device 1 or to exit.
- the first channel 2.1 includes an input 8 allowing the patient to enter said first channel
- the second channel 2.2 includes an output 9 allowing the patient to exit said second channel.
- a channel 2.1, 2.2 has a width of between 1 m (meter) and 5m, preferably between 1 m and 2m.
- the first channel 2.1 may surround the second channel 2.2, so that the second channel is found inside the loop formed by the second channel, or conversely, both 2.1, 2.2 channels communicating through the opening 5.
- the input and output 8, 9 can also be of different depth, relative to each other, or with respect to the channels 2.1, 2.2.
- the first and second bath zones 2.1, 2.2 respectively form a first pool 2.1 and a second pool 2.2, respectively, in which the patient can move during treatment. being partially or totally immersed.
- the first and second basins 2.1, 2.2 are adjacent and communicate with each other through the opening 5, the two liquids are then in contact with each other.
- Each basin is of substantially circular or ovoid shape and is delimited by a wall 3.
- there is a zone of exchange consisting of an interface 6, symbolized by a rectangle in Figure 5, between the liquids of the basins 2.1, 2.2.
- the injection system 10 comprises a first injection head 1 1 provided with a first injection nozzle 12.1 of the first liquid at the temperature Ti opening on the first tank 2.1, and a second injection head 14. equipped with a second injection nozzle 15.2 of the second liquid at the temperature T2 opening onto the second basin 2.2.
- the first injection nozzle 12.1 and the second injection nozzle 15.2 are located on either side of the opening 5 and are directed so that the injection flow F, Fb are located in the vicinity of the opening 5.
- the injection flows F a , Fb are convergent and oriented in co-current. It would obviously be possible to position the injection nozzles 12 and 15 so that the injection flows F a , Fb are divergent.
- the shape of basins 2.1, 2.2 should then be adapted accordingly.
- Flows F a , Fb injection nozzles 12.1, 15.2 contribute to circulate the liquids in their respective basin 2.1, 2.2 according to the currents F1, F2, said currents F1, F2 being swirling due to the particular form basins.
- the currents F1, F2 induced in particular by the injection flows F a , Fb are distinct, that is to say they do not mix and do not do not mix up.
- the exchanges of material and the heat exchanges between the two liquids are minimized and are realized only at the interface, of negligible thickness, denoted e in FIG.
- the combination of the direction and orientation of the flows F a , Fb, and the shape of the basins 2.1, 2.2 contributes to the differentiation of the currents F1, F2 and the maintenance of the liquids of said basins at their respective equal temperature. at T1 and T2.
- the input 8 and the output 9 of the treatment device 1 are merged, and the patient enters and exits said treatment device by the same issue.
- this input / output is located between the two basins 2.1, 2.2, in the extension of the opening 5.
- the inlet and outlet 8, 9 can also be of different depth, relative to each other, or with respect to the basins 2.1, 2.2.
- the bath zones 2.1, 2.2 may comprise, in addition to the injection system 10, liquid injection means (not shown) such as injection nozzles for better circulation of the liquid. and a temperature maintenance of said liquid within said bath zones. These injection means may for example be distributed along the channels or basins 2.1, 2.2.
- the bath zones 2.1, 2.2 may comprise, in addition to the injection system 10, liquid extraction means (not shown) outside said bath zones, such as suction nozzles, these means for example extraction are distributed along the channels or basins 2.1, 2.2.
- the treatment device according to the invention is particularly well suited to the equestrian field and the treatment of horses.
