    FIELD OF THE INVENTION
    [0001] The present invention relates to a device for the care of respiratory diseases and / or for the improvement of lung function, which comprises at least a first flow channel for inhalation, a body part and a liquid space in the body part into the liquid. Furthermore, the invention relates to a method for guiding gas flows in a device that comprises at least a first flow channel for inhalation, a body part and a liquid space in the body part for the liquid. BACKGROUND OF THE INVENTION
    [0002] The incidence of various allergies and respiratory tract infections has increased significantly in recent times. This can easily result in a patient with a respiratory disease being subjected to continuous pharmacotherapy and repeated antibiotic regimens. They can have adverse effects and cause new problems. The mucus excreted in bronchitis and infection factors easily remain in small bronchial tubes and obstructed pulmonary alveoli, so as to cause shortness of breath. Therefore, in practice, it is often difficult for inhaled drugs to have a broad effect on such areas of Organs respiratory organs where therapy is, in fact, necessary.
    [0003] In obstructive lung diseases, such as asthma and chronic obstructive pulmonary disease, airway obstruction restricts airflow during strong exhalation. In asthma, the bronchial tubes are blocked as a result of inflammation and in chronic obstructive pulmonary disease, the symptoms are caused by a long-lasting obstruction and inflammation of the pulmonary alveoli and the resulting stiffening of the chest. In obstructive lung diseases, symptoms include shortness of breath and mucus in the airways. In addition, the symptoms can be aggravated by the chest muscle tension resulting from the diseases. In addition, in acute respiratory tract infections, patients' bronchial tubes can easily become irritated and inflamed. In respiratory tract infections, cough removes mucus and causes it to be elevated from the bronchial tubes. In a patient with asthmatic symptoms, a respiratory tract infection constricts the bronchial tubes and thus causes shortness of breath and mucus cannot be sufficiently removed through coughing, so that mucus accumulates in the respiratory tract and increases risk of contracting, for example, pneumonia.
    [0004] In the care of lung diseases and respiratory tract infections, blowing in a bottle and inhaling steam were used as non-pharmacological home remedies. When blowing into a bottle, the patient blows through a hose into a bottle that contains water. Such a difficult murmur removes mucus and opens the bronchial tubes. Inhalation of steam, in turn, moistens the bronchial tubes and makes the mucus excreted more fluid.
    [0005] Lung diseases increase cardiac load and worsen heart-related diseases, such as the occurrence of arrhythmias (eg, atrial fibrillation).
    [0006] In the care of respiratory diseases and allergies, several vapor inhalers and inhalers have been used to transport water vapor to the lungs through inhalation. However, such devices and methods can involve the disadvantage that the temperature of the water vapor to be inhaled is too high, which can damage the respiratory organs and cause a risk of burns. Furthermore, if the goal is to use water vapor to transport a drug to the lungs, only a part of that drug will reach the lungs, due to the fact that most of the water vapor is not inhaled but evaporated in the air. environment.
    [0007] Publication WO 02/092157 discloses a portable medical gas humidifier, which can be used with portable sources of contained oxygen or other breathable gases. The device consists of a reservoir for water and connections from the breathing air (or gas) source to the patient's breathing device. When connected, the entire source of breathable air (or gas) passes silently through the reservoir and becomes "humidified". The device is intended to humidify the air that a patient inhales. Humidification is achieved by supplying pressurized oxygen from the top of the device inside the reservoir that contains water, in which oxygen is forced to the bottom of the reservoir and produces bubbles to humidify the oxygen that the patient inhales. The oxygen pressure makes inhalation easier for the patient, that is, the inhalation resistance is reduced when such a device is used, in which the patient's pulmonary alveoli are not opened effectively.
    [0008] The publication CN 2297204Y discloses a breathing recovery exercise apparatus, which consists of a container and a breathing tube that is communicated with the container. A deflector is arranged in the container and divides the container into an inhalation air chamber and an exhalation air chamber, which are respectively supplied with an air inlet tube that regulates a pressure and an air inlet tube that regulates pressure. . The breathing tube is formed in a Y-shape inverted by an inhalation tube and an exhalation tube, in which the fins that do not return are, respectively, arranged. The breathing recovery exercise apparatus has an exercise medium with three combined inhalation, exhalation and inhalation and exhalation functions. The pressure in the inhalation air chamber is generated by an external pressure source. Therefore, the device cannot use the exhalation air pressure when operating the device. Furthermore, the positive effect that the user's pulmonary alveoli are opened more effectively, which strengthens the lungs and also improves inhalation efficiency, is not achieved by the device in document CN 2297204Y.
    [0009] GB1332382 discloses a device that can be adjusted to function either as a humidifier or an atomizer. The device comprises a chamber, a valve housing, an upper duct and a lower duct, each of which communicates with a cavity formed in the valve housing. The lower duct also communicates with the chamber. The device also comprises a valve spool received in the cavity to define, with the housing, a valve chamber. When the device is used as a humidifier, the valve spool is positioned to align passageways with the upper and lower ducts to allow air or oxygen to pass from the upper duct to the lower duct through water in the chamber and even a patient through a gas outlet pipe. When the device is used as an atomizer, a passageway for the valve spool is aligned with the upper duct so that gas can pass from the upper duct to the valve chamber through an orifice and water can pass from the lower duct into the valve chamber through a groove, the velocity of the gas through the orifice creating a vacuum in the valve chamber that draws water into the chamber and causes the water to decompose into droplets to form an aerosol, that passes through the orifice and outlet tube for a patient. The GB1332382 device can only be used during the inhalation stage. BRIEF SUMMARY OF THE INVENTION
    [0010] It is an objective of the present invention to reduce the disadvantages mentioned above and to provide an improved device for the care of respiratory diseases. The invention uses resistance exhalation and vapor inhalation combined with it, integrated in a single functional process in which the different stages support each other. Resistant blowing is effective in opening, specifically, the small bronchial tubes at the bottom of the lungs and activates the muscles that travel between the ribs by increasing the volume of the airways. As a result, in the inhalation step, moist vapor can better reach the small bronchial tubes and, at the same time, it makes the mucus more fluid and more easily removable. The invention is, therefore, based on the idea that the device is used for both exhalation and inhalation in such a way that, before the inhalation step, the device is used to provide flow resistance for exhalation; as a result, it is possible, for example, to open pulmonary alveoli and, in such a way, to increase access to the pulmonary alveoli through the moist vapor that flows into the lungs during the inhalation step. Thus, the effect of a drug or other active agent possibly carried by the wet vapor can be accentuated in the lungs. More precisely, the device according to the present invention is mainly characterized by the fact that the device additionally comprises:
    [0011] - a second flow channel arranged in a flow connection with the body part;
    [0012] - a steam space arranged to receive steam that is formed in the liquid space, through which the first flow channel is arranged in a flow connection with the steam space;
    [0013] - means for transporting a flow of exhaled gas from outside the device through the second flow channel to the body part;
    [0014] - means to induce resistance to the flow of exhaled gas flowing through the second flow channel; and
    [0015] - means for transporting a flow of gas from the vapor space through the first flow channel to the outside of the device during inhalation.
    [0016] The method according to the present invention is mainly characterized by the fact that the device also comprises a second flow channel that is arranged in a flow connection with the body part and a vapor space, being that Full name:
    [0017] - a gas flow to the device is transported through the second flow channel to the body part,
    [0018] - induce resistance to the flow of exhaled gas flowing through the second flow channel;
    [0019] - increase the pressure in the liquid space;
    [0020] - as a result of the pressure increase, the vapor produced in the liquid space is received in the vapor space,
    [0021] - the gas flow is transported from the steam space through the first flow channel to the outside of the device.
    [0022] Through the device and the method according to the invention, it is possible to accentuate and facilitate the care of specifically respiratory diseases and intensify the function of the lungs. By applying the device and method according to the invention, it is possible to reduce or even avoid the use of cortisone and other products to open the lungs. In addition, the effectiveness of inhaled pulmonary drugs can be enhanced by the device according to the invention. The effectiveness of inhaled pulmonary drugs currently in use is about 40 to 60%.
    [0023] In normal inhalation, the diaphragm and other costal muscles are concentrated and in exhalation relaxed, the respiratory muscles are relaxed and the air exits as the muscles return from a stretched state to a state of rest. In strong exhalation, the abdominal muscles and the innermost intercostal muscles are used. In this way, the small bronchial tubes and terminal units are contracted more strongly in the lower parts of the lungs than in the upper parts of the lungs.
    [0024] The device can be used, among others, to improve the pulmonary function of elderly patients and children. With age, the chest becomes more rigid and breathing is more shallow, in order to predispose to pneumonia. Children with asthmatic symptoms limit their movements during exercise and get used to more shallow breathing. In this way, the capacity of the lungs is reduced.
    [0025] The device according to the invention can use the patient's own breathing mechanism, among others, by directing the desired resistance over the lungs during exhalation and inhalation, in which even the small bronchial tubes are forced to work; as a result, the accumulated mucus, etc. it can begin to move out of the bronchial tubes more effectively than when prior art solutions are used.
    [0026] In an advantageous embodiment of the invention, during exhalation, air is introduced into a water-drug mixture that is bubbled by pressure and is vaporized into the air space of the device. During inhalation, a separate valve closes the liquid channel and opens the air space, into which a desired amount of replacement air is inserted, if necessary, through a valve above the air space. The replacement air passes through the vapor / drug in the air space of the device to the bottom of the air space and is simultaneously mixed with the vapor mixture. In the inhalation step, a part of the vaporized drug-oxygen mixture formed in the air space is extracted into the lungs and introduced, during inhalation, into the lungs and, moreover, in the most severely inflamed areas where the bronchial tubes small ones become free of mucus and are opened. The vapor to be inhaled into the lungs moistens and dissolves the mucus, in order to make it more fluid and more easily removable.
    [0027] Each repetition can contribute to the effect of the operation and, in some cases, even after about 5 to 10 repetitions, most of the drug was elevated from the liquid to the vapor space and was introduced into the lungs.
    [0028] The patient using the device according to the invention blows, for example, into the liquid or through a block, against resistance, in the same way as in exhalation, in which the pressure in the bronchial tubes increases according to the abdominal and intercostal muscles are contracted and the small bronchial tubes and alveoli at the bottom of the lungs are more contracted. This can contribute to the removal of mucus from the lower part of the lungs and, specifically, the risk of pneumonia can be reduced. In addition, through the device, the patient can inhale a warm vapor, to which it is possible to add salt or a drug to treat the bronchial tubes. The salty water vapor acts in the same way as a physiological saline solution (0.9% NaCl) that purges irritated bronchial tubes and moistens the excreted mucus, in order to make it more fluid and more easily removable. The device can intensify the non-pharmacological care of a respiratory tract infection in each and reduces the risk of pneumonia, specifically, in patients with asthmatic symptoms. In addition, exhalation with active resistance and strengthens the abdominal and intercostal muscles involved in breathing and can improve chest elasticity as well as breathing. Specifically, in obstructive lung diseases, such as asthma and chronic obstructive pulmonary disease, the intercostal muscles are strongly contracted and partly because of this, the chest becomes more rigid. In addition, the vapor to be inhaled can intensify the effect of the device to purge the airways and to remove mucus, specifically in connection with infections. DESCRIPTION OF THE DRAWINGS

    [0038] Figure 1 shows a perspective view of a device 1 according to an advantageous embodiment of the invention and Figure 2 shows the device of Figure 1 in a reduced cross-sectional view. The device 1 comprises a body part 2 whose internal volume is provided with a liquid space 3 for a liquid, such as water. The body part 2 is advantageously thermally insulated, both in part and completely, to reduce heat losses. Above the liquid space 3 there is a vapor space 4, to which the steam raised from the liquid can be transferred. The device 1 also has a first flow channel 5 that can be used at least in the inhalation step, to transport an air flow to the mouth and, in addition, to the lungs of the person to be treated. In conjunction with the first flow channel 5, a first valve 6 is provided, whereby the air flow in the first flow channel 5 can be substantially adjusted or prevented entirely, if necessary, as will be described later in this section. description. The first flow channel 5 extends into the vapor space 4 in such a way that one end 5a of the first flow channel 5 is above the liquid level even during the stage when the liquid space 3 is filled with the liquid. The liquid level in a situation is illustrated with a broken line 18, however, it is obvious that the liquid level can vary in different situations.
    [0039] Although in this context the liquid space 3 and the vapor space 4 are mentioned separately, they are not necessarily separated from each other structurally, but such spaces are formed in the internal volume of the body part 2, in which the term 'liquid space' can be used for the part of the internal volume that is filled with the liquid at the same time and, consequently, the term 'vapor space' can be used for the part of the internal volume for which the vapor can be transferred from the liquid.
    [0040] In the liquid space 3, the wall of the body part 2 can comprise a transparent section 15 (a window), through which the level of liquid in the liquid space 3 can be observed. This can, among other things, facilitate the filling of the liquid space 3, so that it can be seen from the outside of the device 1, when the liquid space 3 is filled with an adequate amount of liquid.
    [0041] The device 1 can also be provided with a lid part 12, through which the liquid, such as water, can be filled into the liquid space 3. The lid part 12 can be tightened in a way relatively tight to the body part 2 so that a sufficient pressure level can be maintained within the body part during use of the device 1.
    [0042] The body part 2 or the cap part 12 is preferably provided with a replacement air valve 19, through which the replacement air can be supplied into the internal volume of the body part in the step inhalation.
    [0043] The device 1 also has a second flow channel 7 to transport the air to be blown into the device 1. In conjunction with the second flow channel 7, a second valve 8 is provided, whereby the Air flow in the second flow channel 7 can be substantially adjusted or prevented entirely, if necessary, as will be described later in this description. Such a second flow channel 7 extends into the liquid space 3 such that an end 7a of the second flow channel 7 is below the surface of the liquid when the liquid space 3 is filled with liquid. In such an embodiment, the first flow channel 5 and the second flow channel 7 are connected to a third flow channel 9. Such third flow channel 9 can constitute a nozzle 10 for device 1 or device 1 can comprise a nozzle separate 10, through which the third flow channel 9 is transported.
    [0044] In some cases, the nozzle 10 can be replaceable, and people who use the device can each have their own nozzle 10.
    [0045] In some embodiments, the second flow channel 7 of device 1 is provided with an adjustable flow resistance, such as a choke, by means of which the resistance on exhalation can be adjusted as needed. On the other hand, in some situations, the resistance to flow can be adjusted by changing the viscosity of the liquid in the liquid space 3.
    [0046] In some embodiments, the first flow channel 7 of device 1 can also be provided with an adjustable flow resistance, such as a choke, whereby the resistance on inhalation can be adjusted as needed. On the other hand, the flow resistance of the first flow channel 5 can, therefore, be high enough to provide adequate resistance in the inhalation step. In some cases, such resistance to flow can be suitably established, for example, in order to select the cross-sectional area of the flow channel in an appropriate manner. If the first flow channel 5 and / or the second flow channel 7 or a part of them is produced from a tube, such as a plastic or metal tube, the flow channel can be established, for example, through the selecting the tube diameter in an appropriate manner or placing a tube with a smaller diameter somewhere in the first flow channel 5 and / or the second flow channel 7.
    [0047] Next, the operation of the device according to Figure 1 will be described in a care situation with reference to Figures 3a and 3b. The liquid space 3 of the device is filled with a liquid, such as water, to a certain level. Such a height level is advantageously such that an end 5a of the first flow channel 5 is above the liquid level, but an end 7a of the second flow channel 7 is below the surface of the liquid. Such an end 7a of the second flow channel 7 forms a type of an opening that connects the second flow channel 7 to the liquid space 3, in which the gas flow flowing through the second flow channel 7 is arranged to be directed to the liquid space 3 to increase the pressure in the liquid space 3. The liquid to be supplied to the liquid space is preferably heated, for example, by means of a separate heating device or the warm water is supplied to the interior of liquid space from a building's hot water tap or the like. The target temperature of the liquid can vary in different situations, however, it was found that in the care of respiratory diseases, the temperature of the liquid should not be boiling, for example, 60 to 70 degrees at the most or even colder. Thus, if the temperature of the liquid is raised above the target temperature in the heating stage, there may be a need to allow the liquid to be cooled down before the device 1 is used by the person to be treated.
    [0048] When the liquid space 3 is filled with an adequate amount of the liquid and the temperature of the liquid is adequate, care measures can be initiated. The person to be treated puts the mouthpiece 10 in his mouth and starts to blow. In this way, the air in the individual's lungs flows into the third flow channel 9 and from then on to the second flow channel 7. In practice, air can also flow into the first flow channel 5, however, the first valve 6 in the first flow channel is in a position that prevents air from flowing into the first flow channel 5. In other words, the first valve 6 prevents air from flowing through the first channel flow rate 5 into the vapor space 4. Instead, the second valve 8 in the second flow channel 7 is in a position that allows the exhaled air to flow into the liquid space 3. The liquid in such a space liquid space 3 generates a resistance to flow that has the effect that the person needs to blow more strongly so that the exhaled air can flow into the liquid space 3. It has been found that this is useful in medical care due to the fact that the muscles involved in the function of the lungs they need to work harder, which also strengthens those muscles when medical care is continued. In addition, the opening of the bronchial tubes is most effective when a force effect of clear resistance is produced against exhalation. The air flows of the stage are illustrated with an arrow A in Figure 3a.
    [0049] In the space of liquid 3, exhalation has the effect that bubbles (pores) are formed in the liquid and the pressure inside the body part, for example, in the space of liquid 3, increases. As a result, a portion of the liquid in the liquid space 3 is evaporated and that vapor is raised to the vapor space 4, although the temperature of the liquid is below the evaporation point of the liquid. If the liquid space 3 or the vapor space 4 contains a drug, delivery of the drug with the inhaled vapor into the lungs is also enhanced. Exhalation is followed by an inhalation step that induces the following current of operations on device 1. When a person begins to inhale through the extraction of air through the mouthpiece 9 into their lungs, a pressure below normal is formed both in the first flow channel 5 and in the second flow channel 7. In this way, the second valve in the second flow channel 7 is closed and prevents the flow of air through the second flow channel 7 into the lungs. Instead, the first valve 6 in the first flow channel 5 is opened and allows air to flow from the steam space 4 through the first flow channel 5 into the lungs. Such inhaled air also entrains steam from the steam space 4; In other words, the device works with a vapor inhaler. The air flows of the stage are illustrated with an arrow B in Figure 3b. Due to the fact that the inhalation step follows the exhalation step substantially immediately, the bronchial tubes do not have time to be closed, which is substantially effective and intensifies access to the lungs by the vapor and possible drugs contained therein. Both the blowing resistance and the inhalation resistance can be adjusted, due to the fact that the lungs and the muscles that support them are activated in the resisted inhalation, too.
    [0050] In step 1 described above, the first valve 6 and the second valve 8 are pressure operated valves automatically, the type of back pressure valves, through which the direction of the air flow can be operated in a controlled manner as desired . In device 1 according to the invention, it is also possible to use other types of valves, through which air flow control can be implemented by applying the principle mentioned above. As an example, manually operated valves can be mentioned. The user or his assistant can adjust the valves according to the need; consequently, in the exhalation step, flow through the first flow channel 5 is impeded and, correspondingly, in the inhalation step, the flow of air through the second flow channel 7 is impeded. In one embodiment, the first valve 6 and the second valve 8 can be replaced by a single valve with a plug (for example, the baffle 16, Figure 4) which can alternatively close the first flow channel 5 and the second channel flow control 7. Valve control 6, 8 can also be implemented by automation, a sensor or similar may be needed to detect whether a person is exhaling or inhaling and, based on this, to control the operation of valves 6, 8 in an appropriate manner.
    [0051] In device 1 of Figure 1, the first flow channel 5 and the second flow channel 7 are connected at one end 5b, 7b to a single flow channel, that is, the third flow channel 9. However, the device 1 according to the invention can also be implanted in such a way that the third flow channel 9 is not necessary, but both the first flow channel 5 and the second flow channel 7 are taken to the nozzle 10, through which both the second end 5b of the first flow channel 5 and the second end 7b of the second flow channel 7 are in the mouthpiece and the person places them in his mouth for the moment of using the device. Said second end 5b of the first flow channel 5 and the second end 7b of the second flow channel 7 are advantageously close to each other, advantageously, in parallel, over or obliquely with respect to each other, such that the second ends 5b , 7b of both flow channels fit into the subject's mouth simultaneously. An example of such a deployment is shown in Figure 5.
    [0052] Regarding the operation of the device 1 described above, it was mentioned that the liquid is heated outside the device 1, for example, through a separate heater, such as a coffee maker, a kettle or the like. The invention can also be applied in such a way that the heating of the liquid is arranged in the device 1 itself, or the device 1 can be heated outside to heat the liquid in the liquid space 3 of the device. Figure 6 shows a reduced cross-sectional view of a device 1 according to another embodiment comprising liquid heating means 11 for heating the liquid. In this way, the heating of the liquid in the liquid space 3 can be carried out by means of the liquid heating means 11. The liquid heating means 11 can be implanted, for example, by means of a heating resistor, in which the electricity is conducted to the heating resistor at the time of heating. The electrical energy required for heating can be conducted, for example, by means of electrical energy transmission means 16 provided at the bottom 2a of the body part or the device can be provided with a stationary electrical wire which is connected, for example, to an electrical outlet or converter when heating is required. If said electric power transmission means are provided in the bottom 2a of the device, the device 1 can be provided with a base 17 with corresponding means which can be connected both directly and inductively to the electric power transmission means of the device. For a person skilled in the art, it will be obvious how such a transmission of electrical energy can be implanted in a wired or wireless manner, so a more detailed description of it in this context will not be necessary.
    [0053] Advantageously, the device 1 also comprises a lid 12 which can be opened and / or removed, for example, to fill the liquid space 3. The lid 12 or the body part 2 can also be provided with a relief valve 13 which can prevent the pressure from being raised too high inside the device 1. The cap 12 can also be provided with an opening, through which a drug or other substance can be filled into the liquid in the liquid space. On the other hand, the internal volume of the device 1, for example, the internal surface of the body part can be provided with a container or the like, to which the drug can be supplied and from which the drug is gradually transferred to the liquid in the liquid space 3.
    [0054] If device 1 is provided with liquid heating means 11 of the type mentioned above, it may also be necessary to provide device 1 with control means (not shown in the attached drawings) to control the heating process, between others, to avoid overheating. With the control means it is possible, for example, to control the temperature of the liquid, in which it is possible to use liquids at different temperatures for different uses.
    [0055] In an advantageous embodiment, the heating means 11 can also be used, among other things, to disinfect the device. In this way, the liquid is heated to a higher temperature than in a medical care situation, for example, to the boiling point (100 degrees). This will clean up at least part of the impurities, so that the use of device 1 in medical care situations can be safer. During the disinfection stage, the use of the device for treatment is preferably prevented. This can be implemented, for example, in such a way that the first valve 6 and the second valve 8 are placed in a position that prevents the flow of air from the liquid space 3 and the steam space 4 to the nozzle 10.
    [0056] Device 1 can also be washed with a dishwashing liquid either manually or in a dishwasher, or ultrasonic cleaning or the like can be used.
    [0057] In the following, some additional heating methods will be briefly presented. Applying them in practice may require that the requirements of the different heating methods be considered in the structure of the device 1, including, for example, heat resistance. One possible heating method is to place the device on a heating element (for example, a hot plate from an electric stove), in which the heat from the heating element is conducted through the bottom of the body part to the liquid in the space of liquid 3. A method of heating of a corresponding type is to use a fire to heat the liquid. Yet another possibility may be to use a microwave oven, in which device 1 is placed in the microwave oven. Thus, device 1 must not contain such materials that may hinder the operation of the microwave oven and which are, in general, underheated by microwaves. Some types of heating methods based on thermochemical phenomena can also be used. In this context, mention should be made of the so-called heating cartridges that can be placed at the bottom of the heating device. Heating cartridges can be based on the use, for example, of sodium acetate, iron dust, quicklime or aluminum chloride.
    [0058] In some cases, the heating means of device 1 can be activated, for example, by a battery, by means of which the device can also be used in situations where there is no separate source of electrical energy available.
    [0059] Device 1 can also be equipped with another automation and control to, for example, inform the user of the device about a possible need for maintenance, display the temperature of the liquid, etc.
    [0060] In an advantageous mode, device 1 is used to store treatment sessions in a memory, so that it is possible to monitor the result of treatments and track progress in medical care. This can be useful, for example, for a nursing employee who can use the data to ensure that medical care has been taken in due course and properly.
    [0061] Figure 7 shows a reduced cross-sectional view of yet another advantageous embodiment of device 1. It comprises pressurizing means 14 to increase the pressure prevailing in the liquid space 3. This may be necessary, for example, in situations wherein the person to be treated cannot blow the air strongly enough into the device 1 during exhalation. The pressurizing means 14 comprise, for example, a piston 14a or the like that can move in the internal volume of the body part, for example, towards the bottom part 2a and in the direction opposite to the bottom part 2a. Such a movement can be produced, for example, by pressing the rod 14b downwards or by raising the rod 14b. Due to the fact that the pressure increase preferably needs to be produced in the liquid in the liquid space 3 and the vapor that forms in the liquid must enter the vapor space 4, the piston 14a is advantageously equipped with channels or the like , through which the steam can be raised into the steam space 4. Although piston 14a is therefore not completely sealed, piston 14a can still be used to increase the pressure in the liquid space 3. Such pressurizing means 14 they can be used, for example, by the user of the device or his assistant. The required pressure level can be set according to the user's feeling, where it is possible to avoid applying too high a pressure.
