For example, in known tissue stimulation methods, a cleansing or stimulating essence is added to a fluid, such as water.

It is the object of the invention to provide an improved stimulation method for treating a tissue and an improved fluid release device.

Presentation of the invention

The object is achieved by a stimulation method having the features of claim 1 and by a fluid release device having the features of claim 5.

Advantageous embodiments of the stimulation method and the fluid release device can be found in the respective dependent claims.

The stimulation method for treating a tissue comprises applying or applying a first fluid having a first temperature T1 for a first time period t ₁ and then a second fluid having a second temperature T2 for a second time period t ₂ to the tissue. Thus, sequentially, the tissue may be exposed to the first fluid at a temperature T1 for a first time period t ₁ and the second fluid at a second temperature T2 for a second time period t ₂ . The tissue preferably has blood vessels and / or muscles, for example hair follicles, and / or sweat glands and / or sebaceous glands and / or tendons. The tissue can be a skin tissue. The tissue, in particular the skin tissue, preferably has one Subcutis (epidermis) and an epidermis (epidermis), in which the muscles and / or blood vessels and / or the sweat glands and / or the tendons are arranged. The tissue may be a scalp with hair roots and hair follicles. The tissue can also be a facial skin with facial muscles. With the stimulation method, a stimulation of the tissue, be feasible. For example, the stimulation method can be used to stimulate or stimulate the action of a specific muscle in the tissue. Thus, for example, the hair follicle muscle can be stimulated to activity, in particular to increased activity, by means of the stimulation method.

In this case, the stimulation method preferably has the steps: Step one: applying a first fluid at a temperature T1 to the tissue for a first time interval t ₁ , step two: applying a second fluid at a second temperature T2 for a second time period t ₂ to the tissue Tissue. Preferably, steps one and two are performed sequentially. Steps one and two can be performed consecutively and alternately. As a result, a treatment of the tissue with the steps one and two over an arbitrarily long period can be realized. The length of the treatment period is preferably adjustable. Likewise, the length of the first step and / or the second step may be adjustable. The time span of the first step may be different from the time span of the second step. The first fluid and the second fluid may contain and / or be the same fluids. Alternatively, the first fluid and the second fluid may also contain and / or be different fluids.

The first fluid and / or the second fluid may in this case be a liquid, for example water. The first fluid and / or the second fluid may / but may also be gaseous and present as gas. The gas may in this case be air, in particular the ambient air of the tissue. For example, in one embodiment of the stimulation method, the tissue may first be exposed to a liquid, such as water, having the first temperature T1, followed by air having the second temperature T2. In a second embodiment, the first fluid may be a liquid, for example water, which has a first temperature T1. The second fluid may also be a liquid, for example water, which has a second temperature T2. Thus, the tissue may first be filled with a liquid, For example, water, with a temperature T1 and then a second liquid, for example water, be exposed to a temperature T2.

In a further embodiment of the stimulation method it can be provided that the application of the first fluid with a first temperature T1 for a first time period t ₁ and then the application of the second fluid with a second temperature T2 for a second time period t ₂ to the tissue a treatment cycle is, wherein the treatment cycle is repeated several times. The treatment cycle here has the duration t _{treatment cycle} = t ₁ + t ₂ . Thereby, a periodic treatment of the tissue with the first fluid at the first temperature T1 for the time t ₁ and the second fluid at the temperature T2 for the time t ₂ over a longer period of time by the treatment cycle is repeated. The time span and / or time duration in each case relate to the duration of the application with the fluid at a defined temperature. The time duration t ₁ and / or the time duration t ₂ here is the time that the first and / or second fluid is applied to the tissue and can act on it. The time duration t ₁ or t ₂ from switching on the application of the fluid until it is switched off is also referred to here as pulse duration t ₁ or t ₂ . The tissue can be treated periodically recurring alternately with a pulse with the first fluid and a pulse with the second fluid. In this case, the time of treatment of the tissue t _treatment can be the sum of the first time duration t ₁ and the second time duration t ₂ multiplied by the number of treatment cycles N: t _treatment = N x (t ₁ + t ₂ ) = NX t _{treatment cycle} .

In a further embodiment of the stimulation method, it may be provided that the treatment cycle is a first treatment cycle and a second treatment cycle is used after the first treatment cycle, wherein parameters such as temperature of the first and / or second fluid, pulse duration of the first and / or second fluid , Design of the fluid and other parameters that relate to the fluid of the second treatment cycle are different from the parameters of the first treatment cycle. The treatment duration t _treatment consists of the sum and the number of the first treatment _cycle and the second treatment _cycle : t _treatment = N ₁ × _{treatment cycle 1} + N _{2 × treatment cycle 2} .

The first fluid at the temperature T1 may preferably be in a first reservoir or Be arranged container. The second fluid at temperature T2 may be received in a second reservoir or container. The first fluid and / or the second fluid, the liquid and / or the gas, are preferably released in succession from the first and the second reservoir. Thus, the first fluid at the temperature T1 and the second fluid at the temperature T2 can be alternately and periodically applied to the tissue. A pulse of the first fluid and then a pulse of the second fluid can be applied to the tissue in rapid succession. The application may preferably be carried out by first opening the first reservoir in such a way that the first fluid can come into contact with the tissue, and then the first reservoir is closed and the second reservoir is opened, so that the second fluid in contact with can enter the tissue. Thereafter, the second reservoir is closed again. If the treatment of the tissue is to be continued, the first reservoir can be opened again and the next treatment cycle can begin. The contact between the fluid and the tissue is in this case preferably a thermal contact.

In one embodiment, the first fluid at the temperature T1 and the second fluid at the temperature T2 may be introduced into a third reservoir, wherein the tissue is arranged in the third reservoir. Thereby, the first fluid and the second fluid can be introduced into the third reservoir, wherein the third reservoir is emptied before the second fluid is introduced into the third reservoir. Thus, the first fluid and the second fluid may sequentially act on the tissue. The third reservoir may be, for example, a hood which is placed around the head of a person. Preferably, the third reservoir is arranged in such a sealing contact with the head that the first and / or the second fluid can be accommodated therein and remain in it for a certain time. The third reservoir preferably has an outlet for emptying the third reservoir. Thereby, the tissue in the third reservoir can be sequentially exposed to the first fluid and the second fluid. There can be no fluid in the third reservoir with a mixing temperature.

Preferably, the temperature T1 is not equal to the temperature T2. In particular, the temperature T1 may preferably be lower than the temperature T2. In particular, the temperature T1 of the first fluid is lower than the temperature of the tissue, for example, the scalp. However, it can also be provided that the temperature T1 is higher than the tissue temperature and the temperature T2 lower than the tissue temperature. Particularly preferably, the temperature difference between the temperature T1 of the first fluid and the ambient temperature is greater than 10 ° C, in particular 15 ° C, particularly preferably greater than 25 ° C. In this case, a temperature difference T2-T1> 10 ° C, in particular <15 ° C, preferably <25 ° C is preferably used. The temperature difference T2-T1 is particularly preferably> 30 ° C, in particular> 40 ° C,> 50 ° C.

The first fluid having the first temperature T1 and the fluid having the second temperature T2 are preferably a fluid, for example water. In this case, first cold water and then subsequently warm water can be applied to the tissue, for example introduced into the third reservoir and act on the tissue. The cold fluid, in particular cold water, preferably has a temperature between 10 ° and 25 ° Celsius, preferably a temperature T between 15 ° and 20 ° C, on. The warm fluid, in particular warm water, preferably has a temperature between 35 ° and 45 ° C., more preferably a temperature between 38 ° and 42 ° C.

Thus, a change treatment with fluids of different physical properties, in particular different temperature, and thus a change-warm treatment of the tissue can be realized. A muscle arranged in the tissue, preferably hair follicle muscle and / or facial muscle, can thus be exposed alternately to the fluid having a temperature T1 and the fluid having a temperature T2, the temperature T1 being lower than the temperature T2. The treatment may also be performed in reverse order so that first a fluid having a temperature higher than the temperature of the tissue may be applied, followed by a fluid having a temperature lower than the tissue temperature. Also in this way, an alternating heat treatment of the tissue can be realized.

When the fluid with the low temperature T1 acts, the muscle, in particular hair follicle muscle and / or facial muscle, contracts preferentially. When the fluid with the high temperature is applied, the muscle, in particular the hair follicle muscle and / or the facial muscle, relaxes again and may become slack.

As a result, the muscle, preferably hair follicle muscle and / or facial muscle, can be stimulated and / or exercised. The stimulated Haarbalgmuskel from a resting phase in an activity phase and thereby can grow a new hair. As a result, the hair growth can be stimulated and activated as a whole. By the successive action of the first fluid and the second fluid on the tissue, in particular the blood vessels, the blood vessels can be stimulated and the blood circulation of the tissue can be stimulated and thus improved.

An effect may also be that sweat glands and / or sebaceous glands present in the tissue are deflated. Overall, the metabolism of the tissue, such as the subcutis (subcutaneous tissue) and the epidermis (dermis), can be stimulated, thereby activating and stimulating the tissue. Due to the alternating heat treatment, it can come to the training and / or the stimulation of the hair follicle muscle, whereby the hair growth can be stimulated. Due to the alternating heat treatment, especially the training and / or the stimulation of the facial muscles wrinkling of the skin can be reduced. If the tissue is traversed by tendons, the tendons may contract upon exposure to the first low temperature fluid T1 and expand upon exposure to the second higher temperature fluid T2. Overall, in this way a tension and relaxation of muscles, blood vessels and / or tendons can be achieved. As a result, for example, caused by the small movement of the tendons and calcification deposits in the tendons. Overall, stresses, for example, in the shoulder, which is traversed with tendons, be dissolved and broken down. By the action of the first fluid with the first temperature T1 and the second fluid with the second temperature T2 on the tissue, blood vessels located in the tissue, in particular arteries and / or veins, can be stimulated and thereby trained. As a result, the blood vessels, in particular arteries and / or veins, remain elastic and / or become elastic again. This can cause protection against and / or prevention of infarcts.

It is advantageous here that it is a stimulation and stimulation of the blood circulation and / or training of muscles, especially hair root muscles and / or facial muscles, based on the effect of the temperature difference between the first and second fluid. There is no need for a chemical agent to achieve the stimulating, stimulating and / or training effects, as used, for example, to stimulate hair growth or increase blood circulation in prior art methods.

Preferably, the fluid is formed as a fluid jet. In this case, the stimulation method for treating the tissue may comprise the application of a fluid jet to the tissue. Here, the temperature of the fluid of the fluid jet may be unequal to the temperature of the tissue. The fluid jet can in this case have a pulse length t. Thus, at least one fluid jet can be applied to the tissue, the at least one fluid jet having a pulsed time structure. The pulsed time structure is preferably composed of a pulse with a first fluid and a pulse with a second fluid. The fluid of the fluid jet preferably has a temperature T that is lower than the temperature of the tissue. Preferably, the temperature T is distinct, at least 10 ° C lower than the tissue temperature. The fluid jet can in this case be applied to the tissue for the first time span or time duration t ₁ , followed by the second time span t ₂ during which no fluid jet is applied to the surface of the tissue, in particular the scalp. The fabric is exposed to ambient temperature. The fluid jet is thereby preferably designed as a pulsed fluid jet with an on-off time structure. The first time interval t ₁ describes the pulse length of the fluid jet. The first time interval t ₁ may preferably be a few seconds. In this case, the fluid jet can act on the surface of the tissue for the duration of the pulse length, that is to say for the first time interval t ₁ . For the time between the pulses, ie the second time interval t ₂ , no fluid with the temperature T1 acts on the tissue. The tissue may then be exposed to ambient air acting as a second fluid. This ambient air is preferably not kept at the temperature T1. The ambient air may have a temperature that is different than the tissue temperature.

Thus, the fluid jet at temperature T1 may be periodically applied to the tissue and may cause a temperature shock in the tissue, particularly for the muscles and / or blood vessels and / or tendons in the tissue. The muscles, for example, prefer to contract or expand depending on whether the temperature of the applied fluid is greater or less than the ambient temperature, in particular tissue temperature. By the alternating action and non-action of the fluid jet, a change-heat treatment of the tissue can be achieved.

The fluid of the fluid jet is hereby preferably act on a surface of the tissue, in particular surface of the skin tissue. The surface of the tissue is the side of the tissue that faces a fluid delivery device, also referred to as a fluid release device.

The pulsed fluid jet is preferably a directed fluid jet. The fluid jet can be directed substantially perpendicular to the tissue, in particular the scalp, whereby a substantially vertical, an angle of incidence of ± 30 ° C, in particular ± 20 ° C, preferably ± 10 ° C should be understood.

In one embodiment, the fluid jet may be a first fluid jet and a second fluid jet may be provided. In this case, the fluids of the first fluid jet and of the second fluid jet preferably have different temperatures. The first fluid jet and the second fluid jet can be alternately and sequentially applied to the tissue, in particular the skin tissue, and thus act. It acts on a sequence of fluid jets at different temperatures on the tissue, in particular skin tissue. Preferably, the pulsed fluid jet is a cyclically pulsed fluid jet. In this case, as a function of time, the first fluid jet having a pulse length Δt ₁ can follow a fluid jet-free time interval Δt ₂ , and then the second fluid jet can act on the tissue with a pulse length Δt ₃ , followed again by a fluid jet-free time interval Δt ₄ . This fluid jet pattern can then be repeated. As a result, a fluid action of different fluids at different temperatures can be realized periodically on the tissue, for example on the skin tissue. The different temperatures of the first fluid jet and the second fluid jet may enhance the effect of the interaction of tissue contraction followed by tissue relaxation and / or muscle relaxation. As a result, the effect of increasing the circulation and / or activating the hair follicles and thus stimulating hair growth can be achieved. In particular, a Stimulation of the regeneration of the hair root can be achieved.

In one embodiment, the at least one fluid jet may comprise an array of fluid jets. As a result, the first and / or second fluid can be uniformly applied to a larger area of the tissue. The fluid jets may be directed fluid jets.

The stimulation method may be performed, for example, by connecting a device that can emit a fluid jet to a normal water line and the fluid jet is, for example, a jet of water. The fluid jet may in this case be pulsed, that is, switched on and off. The stimulation method can be particularly effective if one or more cold water jets are applied simultaneously and periodically to the tissue, in particular the scalp. In this case, the geometric arrangement of the fluid jets is preferably determined by the geometry of the surface of the tissue, for example the geometry of the head. Thereby, the fluid jets can be uniformly applied to the surface of the tissue and applied. The effect of temperature can be approximately the same at any point in the tissue.

Here, the temperature T1 and / or the temperature T2 of the fluid jets is preferably a temperature that is perceived as cold. The temperature T1 and / or the temperature T2 are below the body temperature of the tissue. Preferably, the temperature T1 and / or T2 <20 ° C, in particular <15 ° C, more preferably <10 ° C. The temperature T1 and / or T2 may also be less than zero. The action of the fluid jet at a temperature less than the tissue temperature, the tissue can contract, it can also affect the blood vessels, which pull through the tissue, cause the circulation of the tissue. In the fluid-free time, the tissue can relax again and the blood vessels are widened. As a result, the tissue, in particular the blood-perfused tissue, experiences a changing stimulus as a result of the pulsed action of the cold fluid. This changing stimulus can lead to an excitation, in particular an increase in the circulation of the tissue. This alternating stimulus can lead to the training of muscles, such as hair follicles. This can stimulate hair growth. It can also be provided be to set the temperatures T1 and / or T2 greater than the tissue temperature or to set at least one of the temperatures T1 and / or T2 greater than the tissue temperatures.

Preferably, in the stimulation method, the first and / or the second fluid jet fluid is under a pressure, wherein the pressure is increased such that a massaging effect can be exerted on the tissue. The pressure can be increased in proportion and in comparison to a pressure prevailing in a water supply system. Preferably, the pressure is greater than 0.5 bar, in particular 1 bar relative to the normal pressure of a supply line for the fluid release device. Particularly preferably, the pressure can be greater than 1.5 bar above normal pressure. As a result, a slight pressure can be built up by the fluid jet on the tissue. This pressure can lead to an additional mechanical action and thus to an intensification of the stimulation. In particular, a massage effect can be achieved. As a result, the muscle, in particular the hair follicle muscle and / or the facial muscle, can be more stimulated and exercised. Furthermore, the circulation can also be stimulated and thus increased. It can also be a microcirculation achieved by the massage of small blood vessels.

In the stimulation method, the first time interval t ₁ and / or the second time interval t ₂ and / or the pulse length of the fluid and / or the fluid jet may be 3 to 20 seconds, preferably 4 to 12 seconds, particularly preferably 5 to 8 seconds. Here, the exposure time, the time that the fluid jet is applied to the tissue. Thus, the contact time corresponds to the pulse length of the fluid jet. During the exposure time, for example, the hair follicle muscle in the tissue may contract when the first fluid is applied to the tissue at a temperature T1 that is less than the tissue temperature. This stimulation can be visible by putting the hair up for the period of time. When the pulse is terminated by the cold fluid and a second fluid having a temperature T2 which is higher than the temperature of the tissue and which is perceived as warm, is applied to the tissue, the tissue can relax, the hair follicle muscle can stretch and the body can relax Hair turns flat again. Thus, the exposure time and the pulse length of the first fluid and / or the second fluid are each a measure of the time of tension and relaxation of the tissue and thus of the muscle. For the different effects to be achieved are different pulse lengths possible. For example, for hair growth stimulation, a pulse length of 4 to 8 seconds, in particular 7 seconds has proven successful. For the stimulation of veins in the tissue, for example for the treatment and relief of varicose veins, a pulse length of about 10 seconds is promising.

The fluid release device for stimulation of a tissue with at least one fluid supply device and a fluid release device is set up, a first fluid having a first temperature T1 for a second span t ₁ and then a second fluid having a temperature T2 for a time t ₂ and / or at least one pulsed one Fluid jet free to set and apply to the tissue.

The fluid release device for stimulating a tissue having at least one fluid supply device and a fluid release device may be connected to a first line for a fluid of temperature T1 and to a second line for a fluid having a second temperature T2. As a result, the fluid at the temperature T1, preferably a cold fluid, can be applied to the tissue. Thereafter, the fluid at the temperature T2, preferably a warm or hot fluid, can be applied to the tissue. In particular, no mixing temperatures are applied since the fluid from the first line can flow directly into the fluid release device. The fluid of the second conduit may also flow directly into the fluid release means. There is no region outside the fluid release device, in particular a line region, which is acted upon by a mixture of fluid having the first temperature T1 and fluid having the second temperature T2. As a result, only the shock effect of the application, in particular alternating application of the fluid with the temperature T1 and the fluid with the temperature T2 can be realized.

Preferably, the fluid release device is characterized in that the first line and the second line are individual separate lines. Alternatively, the first line and the second line can also be designed as a double tube. The double tube in this case has a first fluid guide for the fluid with the first temperature T1 and a second fluid guide for the second fluid with the second temperature T2. Preferably, the first fluid guide and the second fluid guide are thermally insulated in this case.

The fluid release device is preferably connected to a first fluid conduit system for cold fluid and to a second fluid conduit system for warm fluid. Thus, two separate fluid delivery systems for fluids of different temperatures are connected to the fluid release device.

The fluid delivery device, which may also be referred to as a stimulation device, may serve to stimulate a tissue and be used to stimulate a tissue. The tissue is preferably a skin tissue with blood vessels, muscles and / or tendons. The muscles are preferably hair follicles. The fluid release device has a fluid supply device and a fluid release device, wherein the fluid release device is set up to release a fluid jet having a pulsed time structure.

Thus, a method for treating a tissue, preferably a stimulation method for treating a tissue, can be carried out with the fluid-release device. More preferably, the stimulation device can be used to stimulate hair follicles, in particular to stimulate their activity, and thereby to stimulate and / or activate hair growth. The stimulation device can also be used to stimulate blood vessels and thereby to increase blood circulation. The device may in this case release a series of fluid jets which are separated in time. That is, the fluid release device in operation, as a function of time, emits a first fluid jet for a preferably adjustable first time t ₁ , followed by a second fluid free jet time t ₂ , followed by a second fluid jet having a first or third one Duration, again followed by a fluid-free period. The time duration for which the fluid jet can act on the tissue is referred to as pulse length t ₁ or interval length t _{1 of} the fluid jet. Thus, the fluid release device emits a pulsed fluid jet with the pulse length t ₁ . The duration of the fluid jet, which can be applied to the tissue, is hereby preferably described by the parameter fluid jet pulse length. The fluid jet pulse length and / or the intermediate fluid pulse length are preferably adjustable. For this purpose, the device may have a pulse length selection device. Further, the apparatus may be a time setting means for setting the first time period between the first and having the second fluid jet. The time setting device is set up such that the pulse length of the fluid jet can be set independently of the length of the time duration between two fluid jets.

In an embodiment of the fluid release device, an activatable control device, for example a valve device, may be provided, which is arranged between the supply line device and the fluid release device, wherein the pulsed fluid jet can be generated by means of the control device.

In a preferred embodiment of the fluid release device, a first container for receiving a first fluid having a first temperature T1 and at least one second container for receiving a second fluid having a temperature T2 is provided, wherein the first container and the second container are connected to the fluid release device. Thereby, the first container can be filled with a cold fluid and the second container can be filled with a warm fluid. As a result, the fluid release device is set up to apply a first, cold fluid jet to the tissue and immediately thereafter a second, warm fluid jet. As a result, rapid generation of a cold and a warm fluid jet can be realized. Thus, a rapid change of the release of the cold and warm fluid can be made possible. No intermediate temperature fluid is generated and released onto the tissue. The rapid succession of the action of the first fluid and the second fluid may allow for the stimulation effect and / or training effect on the tissue, particularly the muscles and / or veins in the tissue.

In an alternative embodiment, the fluid release device may comprise a container, wherein in the one container, a heater for the fluid is arranged. In this case, the heating device is preferably set up and designed such that the heating of the fluid from a first, cold temperature to a second, warm temperature takes place rapidly. In this case, the heating device can be controlled and regulated in such a way that the fluid release device releases the fluid at a defined first cold temperature and subsequently at a defined second, warm temperature, without the fluid being released at an intermediate temperature.

In a further embodiment of the fluid release device, a control device is provided, by means of which alternately the first fluid and the second fluid from the first container to the fluid release device is conductive. By the control device, the first container and the second container can be alternately connected to the release device. In this case, a cold fluid can be arranged in the first container and a warm fluid can be arranged in the second container. The temperature difference between the first fluid and the second fluid is in this case preferably more than 10 ° C., preferably more than 20 ° C., in particular more than 30 ° C.

The fluid release device preferably has a time setting device and is set up to set the pulse length of the fluid jet and / or to set the intermediate time between two successive fluid pulses. The pulse length can also be referred to as the interval length of the fluid jet.

In one embodiment of the fluid release device, a pressure adjustment device is provided. As a result, the pressure of the fluid can be adjusted. Thus, the fluid release device is adapted to apply a fluid jet or a first and / or a second fluid under an adjustable pressure on the tissue. The pressure may in this case preferably be changed during a contact time of the fluid and / or fluid jet. It is also preferably a sequence of fluids with different pressure adjustable. It can also be provided that the pressure changes during the contact time of the first fluid, for example. This can be done continuously or in jumps.

Preferred embodiment of the invention

FIG. 1 shows in a schematic cross-sectional representation of a tissue 10, in particular a scalp 10. The scalp 10 has a subcutis 12, which is also referred to as a subcutaneous tissue, and an epidermis 14, which is also referred to as dermis. Between the subcutis 12 and the epidermis 14, a layer 16 is arranged, which is referred to as dermis 16. In the dermis 16 hair roots 18 are arranged. Shown is a hair root 18, which is surrounded by an outer layer 20. Further, at the hair root 18, a matrix 22, which is also referred to as hair bulb 22, a hair papilla 24, a bead region 26 and a hair follicle muscle 28 is arranged. Between the epidermis 14 and the dermis 16, a basal membrane 30 is arranged. At least one sebaceous gland 32 is disposed at an upper end of the outer layer 20 of the hair root 18. The hair root 18 and the hair papilla 24 form the invisible part of a hair. The hair root 18 may typically be divided into a resting region 34 and a growth region 36, wherein the growth region 36 is a region 36 of cyclic growth. In the dermis 16 also fibroblasts 38 are arranged.

To the hair root 18, which is arranged in the dermis 16, a hair shaft 40 connects and finally a hair tip 42, which together form the visible part of the hair. The hair is thus composed of the non-visible part, the hair root 18 and the hair bulb 22, and the visible part, a hair shaft 40 and a hair tip 42 together. The material of the hair has a long horn thread and consists essentially of keratin, a water-insoluble fiber protein.

Growth of the hair is based on the hair root 18. The hair grows in cycles. Here, the hair root 18 and the hair bulb 22 forms a hair follicle, which undergoes several phases during a growth cycle. An average growth rate of the hair is approximately between 0.3 and 0.5 mm / day, on average 0.33 mm / day, which means about 10 to 15 cm per year. Hair can fail, which is normal. The hair loss in humans on a scalp 10 is about 60 to 100 pieces per day. The hair growth determining part is the hair follicle. Hair growth is divided into three phases.

In the active growth phase (Anagen phase), which lasts two to six years, the hair cell division is at a maximum. Approximately 85% to 90% of the hair on the human scalp is in the anagen phase.

In a transitional phase of about two weeks (catagen phase), the matrix ceases its activity, the hair follicle narrows in the lower area and atrophies. This stops the hair from growing. Approximately 1% of the hair on the human scalp 10 is at this stage.

In the final three-month phase (telogen phase), the same hair follicle can regenerate and start building new hair. The new hair can then continue to grow for two to six years. Approximately 18% of the hair on the human scalp 10 is in this phase.

FIG. 2 describes a first embodiment of a fluid release device 50, hereinafter referred to as device 50, for performing a stimulation method.

The embodiments of the devices 50 and 76 shown in FIG FIGS. 2 and 3 can also have a timer (not shown), by means of which a treatment length can be set for a stimulation method. The containers 52 and 78 are preferably connected to a cold water line of a standard water supply system. The containers 54 and / or 80 are preferably connected to a standard hot water supply. In an alternative embodiment of the device 50 and / or 76, the containers 54 and / or 80 can be connected to a cold water line and have a heating device for heating the fluid in the container 54 and / or 80. Thus, higher temperatures for the fluid can be achieved.

The fluid release device 68, 90 and / or the nozzle device 74, 92 may have a geometric shape adapted to the human head shape, for example in the form of a hood having nozzles 74, 92 for releasing at least one fluid. The release device 68, 90 and / or the nozzle device 74, 92 is preferably adapted to withstand cold temperatures of up to 0 ° C and high temperatures of up to about 50 ° C, wherein openings of the nozzle device 74, 92 and / or nozzles 74, 92nd can release the fluid at both temperatures.

The fluid can be water. Alternatively, the fluid may also be a gas, for example air. Thus, for example, the first container 52, 78 may contain water and the second container 54, 80 may contain air. As a result, both a liquid, such as water, and a gas, for example air, can be used as a stimulating fluid.

The fluid release devices 50, 76 may be connected to a computer system (not shown) that controls the parameters of the pacing procedure. For example, these are the parameters pulse length of the fluid jet, sequence pattern of fluid jets of different temperature and pulse length, admixture of additives to the respective fluid, total treatment time, and other suitable parameters more.

FIG. 4 shows an example of a pulsed fluid jet 93 with a pulse length 94 or interval length 94 of the fluid jet. The time t is plotted on an x-axis 96. On a y-axis 98, the released fluid jet 93, in particular the intensity I of the fluid jet 93 is applied. At time t ₀ , a valve (not shown) is opened by means of the regulating device 72, 96 and the fluid jet is released into the line 64, the line 66 or the line 88. As a result, the fluid can reach the tissue 10, in particular the scalp 10, through the release device 68, 74, 90, 92. The fluid jet 93 is applied to the tissue 10, in particular the scalp 10, until the time t ₁ . The time t ₁ -t ₀ is referred to as interval length 94 or pulse length 94, or pulse length 94. In the time t ₂ - t _{1 there} is no release of the fluid. The valve in the control device 72, 96 is closed. The interval length 94 is typically 5 to 10 seconds, preferably 7 seconds. The time between two intervals is typically between 20 to 30 seconds. Here, the time interval between the intervals, in particular fluid jets 93, preferably between 3 to 5 times as long to give the tissue, in particular the scalp 10, time to relax again after a fluid jet 93, which can act as a stimulation pulse. The interval length is 94 adjustable and may be different depending on the application of the stimulation method.

It can also be provided to operate the stimulation device 50, 76 in such a way that a first fluid jet 93 is applied to the tissue 10 in the time t ₁ -t ₀ and a second fluid jet (not shown) in the time t ₂ -t ₁ with a pulse length t ₂ -t _{1 is} applied to the tissue 10. Here, the first fluid jet 93 and the second fluid jet have different physical and / or chemical parameters. This may be, for example, a different temperature and / or a different composition and / or different fluid media of the first fluid jet 93 and the second fluid jet.

FIG. 5 1 shows a flowchart of a stimulation method 100. The stimulation method 100 is suitable for stimulating and stimulating the hair follicle muscle and / or for stimulating the perfusion of the tissue. In summary, the stimulation method has the features that an alternating fluid pulse of a first fluid is applied to the tissue 10, in particular the scalp 10. The alternating fluid pulse comprises in particular the application of a fluid having a temperature T1 less than the temperature of the tissue 10, in particular the scalp 10, to the tissue, in particular the scalp 10, followed by the non-action of the fluid on the tissue 10. During the period of non-action the fluid may relax the tissue 10 and the muscles or vessels disposed in the tissue 10. The effect of the application of the fluid followed by the non-wine effect of the fluid is the effect of a temperature difference on the tissue 10, whereby a stimulation of the tissue 10 arranged muscle, such as the hair follicle 28, can take place. In this way, the regeneration of the hair follicle can be stimulated and thus hair growth can be stimulated. In this case, the outer layer 20 can contract around the hair root 18 (first fluid pulse) and relax again (second fluid pulse). Thus, a training of the hair follicle can take place, which controls the growth of the hair.

In method step 102, the release device 68, 74, 90, 92 is arranged on the tissue 10, for example the scalp 10. On the fabric 10 means that the release means 68, 74, 90, 92 are so in relation to the surface of the fabric 10, for example the scalp 10, it is arranged that the fluid can act directly on the surface of the tissue 10, for example the scalp 10. Alternatively, depending on the application of the stimulation method, the release device 68, 74, 90, 92 may have a geometric shape adapted to the tissue 10 to be stimulated. For example, if the tissue 10 to be stimulated is a calf, the release means 68, 74, 90, 92 will be a cuff that can be placed around the calf so that the fluid, such as fluid jets, can act on the surface of the calf.

In method step 104, a fluid jet 93 having a temperature T1 which is smaller than the temperature of the tissue 10, for example the scalp 10, is applied to the tissue 10, for example the scalp 10. In this case, the fluid jet 93 is released from the release device 68, 74, 90, 92 for a time t ₁ -t ₀ and can act on the tissue 10, for example the scalp 10. The time interval t ₁ -t ₀ or time duration defines the interval length 94 of the fluid action. Characterized in that the fluid is colder than the temperature of the tissue 10, for example the scalp 10, a stimulation stimulus can be exerted on the tissue 10. The tissue 10, for example the scalp 10, may contract. In particular, muscles located in the tissue 10, such as the hair follicles 28, may contract and thereby stimulate the area of the hair root, such as the outer layer 20. The stimulation may be a pulling force on the outer layer 20, which is triggered by the Haarbalgmuskel 28 contracts. The stimulation can take place here over the entire interval length 94.

In method step 106, the control device 70, 94 is closed and thus the release device 68, 74, 90, 92 can no longer release fluid at the temperature T1. As a result, the cold irritation remains on the tissue 10, for example the scalp 10, in particular the hair follicle muscle 28, and the tissue 10, for example the scalp 10, can relax again. The method step 106 is used, for example, for a second time duration t ₂ -t ₁ . The second time duration t ₂ -t ₁ is preferably greater, in particular the factor three greater, than the first time duration. As a result, the tissue 10, for example the scalp 10, has more time to relax. The muscles can expand again and return to their original state.

The method steps 104 and 106 are executed several times, in particular between ten and fifty times, one behind the other and alternately. As a result, a change treatment, in particular an alternating pulse, can be achieved. This allows for alternately tensing and relaxing muscles, such as hair follicles 28, and / or blood vessels, such as veins, in the tissue 10. In particular, the effect of a temperature difference on the tissue 10 can result in the stimulation of the tissue 10. The fluid serves as a transmission medium or transfer medium. As a result, a training of tissue 10, for example, a training of muscles, such as hair follicles 28 and / or facial muscles done. It can also lead to training other vessels, such as veins.

In method step 108, the treatment is ended. This can be done automatically, for example, by a preset time on a timer, for example, which is connected to the device 50, 76 or is integrated into, has expired. Alternatively, the device 50, 76 can also be switched off manually. Typical times for the duration of the stimulation procedure are 20 to 60 minutes. The stimulation method 100 may then be applied for several days in a row. The pacing procedure can also be repeated weekly or fortnightly.

FIG. 6 shows a further embodiment of a stimulation method 110. In method step 112, the release device 68, 74, 90, 92 positioned in relation to the tissue so that an action of a first and a second fluid jet can take place.

In method step 114, a first fluid jet having a first temperature T1 is applied to the tissue 10 for a first time duration, so that the first fluid jet can act on the tissue 10. In this case, the first fluid jet can be applied to the tissue 10, for example the scalp 10, as a directed fluid jet, for example.

In method step 116, a second fluid jet having a temperature T2 is allowed to act on the tissue for a second period of time. In this case, the second fluid jet can be applied to the tissue, in particular the scalp 10, as a directed fluid jet.

The temperature T1 is in this case clear, preferably more than 10 ° C lower than the temperature T2.

The process steps 114 and 116 are performed alternately. After a total treatment time, the method is terminated in method step 118. The total treatment time is preferably the sum of the first and second time periods, that is, at least the sum of the pulse lengths of the first and the second fluid jets. The first time duration may be equal to the second time duration. Alternatively, the second time period is greater than the first time period. As a result, the treatment times with the first fluid and the second fluid may have different lengths. The temperatures T1 and T2 are different and preferably have a temperature difference of more than 10 ° C. Preferably, the temperature T1 is different by 10 ° C, preferably 15 ° C, in particular by 20 ° C, in particular lower than the temperature T2. The temperature T1 may in this case, for example, between 12 ° C and 30 ° C, in particular between 12 ° C to 17 ° C, lie. The temperature T2 may be between 36 ° C and 50 ° C, in particular between 38 ° C and 45 ° C. The first time period and / or the second time duration are preferably between 5 and 10 seconds, in particular 7 seconds. It can also be provided that there is a time t ₃ between the exposure time t ₁ -t ₀ with a fluid jet pulse at a temperature T1 and a second fluid jet pulse at a temperature T2 and an exposure time t ₂ -t ₁ without the action of a fluid jet. This may be greater than the first and / or the second time period t ₂ -t ₁ .

It can also be provided to apply a first fluid jet having a temperature T1 to the tissue 10 and then to provide a fluid jet-free time in which the tissue 10 is then exposed to the ambient air.

The method is ended in method step 118. This can be done either automatically or by a manual abort of the method steps 114 and 116. This may be, for example, a manual shutdown of the fluid release devices 68, 74, 90, 92.

The fluid can be applied to the fabric 10 under normal pressure in the method 100 and in the method 110. Alternatively, the device for generating the fluid jet a pressure booster (not shown in FIG FIGS. 2 and 3 ), by means of which the fluid, first and / or second fluid can be applied under increased pressure to the tissue. As a result, in addition a massage effect can be achieved by mechanical stimulation of the tissue.

The stimulation method 100, 110 for treating a tissue 10 can be used as a metabolic conveying method, as a massage method, as a hair growth-promoting method and / or as a circulation-promoting method.
