Description

The present invention relates to a stimulation device with extension for erogenous zones, in particular for the clitoris, a system with a stimulation device, and methods for stimulating body parts.

The erogenous zones of the human body can be stimulated with a variety of aids. For example, vibrators are used to exert a stimulus on a specific skin area by direct contact. These include stimulants for introduction into the human body, such as dildos.

The direct stimulation of the clitoris, for example, with a Auflegevibrator, is often problematic. For example, in women the clitoris is usually the most sensitive erogenous zone. The entire clitoris is heavily endowed with nerve endings, making it particularly sensitive to touch and susceptible to sexual stimuli. Here, in particular, the clitoris sickle, in which the nerve cords of the two thighs meet, should be emphasized. Thus, on the one hand frequent application of a laying vibrator for direct stimulation leads to habituation effects or to conditioning of the stimulated erogenous zone, while on the other hand the initial applications of such a device require a certain training or familiarization. Also, indirect stimulation of the female erogenous zones may not be sufficient, or it may be desirable to enhance the stimulation effect.

In addition, medical studies conducted in 2006 determined the female clitoris as the main starting point of the female climax and neurologically demonstrated the different sensory qualities of clitoral and vaginal orgasm for the first time. So both the clitoris and the vagina are capable of orgasm.

Furthermore, the sensitivity of the human erogenous zones, for example the clitoris, the inner and outer Labia or the nipples, is individually very different. Also, the sensitivity of the corresponding zone can vary greatly from situation to situation or even during a sexual act. It is also often desirable to have fast and strong stimulation of different erogenous zones.

There are various direct and indirect forms of stimulation common practice, such as vacuum pumps or dildos.

For indirect stimulation of erogenous zones, and in particular of the clitoris, conventional vacuum devices are used to stimulate the erogenous zones of the subject without direct contact with the main area to be stimulated. For example, vacuum pumps for the female primary or secondary genitalia are known, which usually have a suction cup for placement and a hand pump. For example, the negative pressure exerted on the clitoris with this type of device creates a negative pressure in the clitoris itself, which is usually lower than the systolic blood pressure. This pressure difference leads to an enlargement of the clitoris and / or stimulates blood flow in the affected area. This clitoral vascular blood flow serves to stimulate pleasure by increasing the sensitivity as well as the optical and haptic manipulation. Also, the better blood flow leads to increased leakage of vaginal moisture, which makes the stimulation more pleasant. However, the manual operation of the hand pump is often annoying or disturbing. In addition, habituation effects can also occur in this device category as a result of the longer-term or uninterrupted application of negative pressure, which permanently restrict the effectiveness of the device.

Instead of the manually operated vacuum pump increasingly electrically driven vacuum pumps are used. As an example, the disclosed WO 2006/05 82 91 A2 a device for sexual therapy, the assembly consisting of a tubular suction chamber for the clitoris, an electrical vacuum source (vacuum pump) and a plurality of air flow openings. Through the operation of the vacuum pump, a continuous air flow or air exchange in the region of the clitoris is generated in the chamber. It is disadvantageously sucked off by the negative pressure increasingly occurring vaginal moisture, which is why a drying effect of the stimulated skin areas occurs. Likewise, the extracted moist air leads to contamination of the fluidically subsequent vacuum arrangement, such as the vacuum pump. Thus, such arrangements with vacuum pumps may be problematic in terms of their hygiene, since the vacuum pump and the associated valves or ventilation components often have dead spaces or dead angles and / or are difficult to clean. Further, the device serves the therapy of the blood vessels of the clitoris, and not the stimulation until sexual climax.

The US Pat. No. 6,464,653 B1 discloses therapeutic devices and methods that produce clitoral flushing by means of a vacuum generated by a vacuum pump to assist in the treatment of clitoral disorders, such as incontinence. By means of a control valve or modulator, which can be covered with the finger accordingly, the height of the vacuum in the suction chamber is manual set or varied. This requires the user's attention and may be distracting or distracting. Also, this relatively complex device with other valves on the above-mentioned disadvantages of hygiene and dehydration, the device also serves long-term therapeutic purposes and not short-term sexual stimulation.

Thus, the devices of the prior art have the common drawback that the complexity of the negative pressure or pressure-generating arrangements can be high and this device can have hygienic problems. In addition, there is the problem of the handling of the devices; these are often haptically uncomfortable and / or getting used to.

Further, the devices of the prior art have the further disadvantage that habituation effects occur with longer-lasting or continuous or frequently recurring applications of suppressions.

Another disadvantage with some of the vacuum devices described above is that, firstly, the vacuum must be limited by means of a control valve or a vacuum pump, and second, the vacuum should be relieved by means of a manual opening of a release valve before the suction cup is detached from the skin. If one of the valves has a technical defect and / or the user operates the unit incorrectly, there may be a risk of injury.

Thus, in view of the problems discussed above, the object underlying the invention is to provide a stimulation device which has a simple structure and is simple and safe to use, and has a strong stimulation effect.

The object underlying the invention is achieved by the stimulation device according to claim 1. Advantageous developments and embodiments are the subject of further independent and dependent claims.

According to the invention, a pressure field generating device of the stimulation device has at least one first chamber and at least one second chamber with at least one opening for placement on a body part or on the erogenous zone and at least one connecting element which connects the first chamber to the second chamber.

By virtue of this construction according to the invention of chambers communicating fluidly via at least one connecting element, a pressure field in the second chamber can be generated in a simple manner by changing the volume of the first chamber, which is directed at times to the skin area to be stimulated.

A pressure field in the sense of the invention is a time-varying field of media pressures, which at times has overpressures and temporary negative pressures, where a negative pressure is a medium pressure which is below the reference pressure, and an overpressure is a medium pressure which is above the reference pressure. As a result, the medium flows back and forth in the pressure field according to the invention. Thus, preferably, a (largely) intermittent exchange of the same medium take place.

The medium is usually gaseous, preferably air, but may for example alternatively or additively be a liquid medium, for example water or commercial lubricant. For example, the lubricant may be introduced into the chambers according to the invention before use of the stimulation device. In this way, the stimulation of the corresponding skin area instead of air can also be done with a suitable skin-friendly liquid, which may be desired depending on the individual preference of the user. As another example, the stimulation device may also be used under water with water as the medium (for example, in the bathtub). In this case, the stimulation device is made waterproof.

The reference pressure is usually the ambient pressure relative to the stimulation device at the beginning of the application (i.e., prior to placement of the stimulation device on the skin area to be stimulated). In the preferred application of the stimulation device with air, the reference pressure is the currently existing air pressure or the normal pressure. For example, in the application of the device under standard conditions, the reference pressure about 1 bar, and consequently a vacuum according to the invention, for example, 0.7 bar and an inventive overpressure, for example, 1.3 may be.

Due to the pressure field according to the invention, the skin area to be stimulated is stimulated on the one hand in its blood circulation, while on the other hand it is indirectly massaged. This combines two beneficial effects. Due to the increased blood flow, the person's erogenous zone is more sensitive, while also creating a massage effect that serves to stimulate the erogenous zone, for example, from sexual arousal to climax. The massage effect is due to the kinetic energy of the flowing from the first chamber through the connecting medium generated against the surface of the skin area to be stimulated. In this way, the created by the pressure field massage effect indirectly, ie without direct contact of the skin to be stimulated by a solid body, for example by a vibrator generated.

By the exemplary application of the invention temporally changing pressure field on the clitoris, an irritation is mimicked by the pressure field, which usually takes place during sexual intercourse. The cohabitation movement also generates an alternating stimulus on the clitoris. Thus, it is a close-to-life imitation of the natural cohabitation act, with medical statements confirming that the application of the pressure field according to the invention leads neither to habituation effects nor to addiction. This is due in particular to the alternating application of underpressure and overpressure (or also in the non-continuous application of only one type of pressure).

Furthermore, the maximum applicable pressure is regularly limited by the maximum load capacity of the skin area to be stimulated. For example, too high a negative pressure, especially in erogenous zones, carries the risk of painful injuries. Only suppression pacing devices are usually limited in their operation to this maximum. In contrast, according to the invention, an extended working range of the stimulation-triggering pressure field or effect is created by the combination of positive and negative pressures, since the working range of the pressure can now be exploited to the maximum in both the positive and the negative range.

By aligning the at least one connecting element on the skin area to be stimulated, the pressure field can act directly, the pressure field being decisively influenced by the configuration of the at least one connecting element and the at least one opening from the connecting element into the second chamber, and thus depending on the application Stimulation device is adjustable. Thus, the at least one opening of the connecting element can be located opposite the body part to be stimulated, preferably directly. For example, in a stimulation device intended for the clitoris, the connecting element may have a single through-opening with a jet effect on the clitoral sickle between the first and the second chamber. Alternatively, the at least one connecting element may consist of several, for example four, through-openings between the chambers, if a larger-area skin area is to be stimulated.

Next arises after placing the half-side or partially open second chamber on the skin area to be stimulated a self-contained system of media or air flow in the pressure field generating device. Thus, the medium or the air is significantly reciprocated between the chambers, while an exchange with media or with air from outside the system is at least largely avoided. Thus, the first chamber is preferably connected via or through the connecting element exclusively with the second chamber. Thus, there are no other connections of the first chamber than those to the second chamber; For example, there is no direct connection of the first chamber with the environment of the device via a pressure valve or via a Luftabführkanal.

For example, in the flow system of the present invention, the temperature of the air in the flow system of the present invention will quickly adapt to the skin temperature while avoiding the disturbing supply of new (eg, cold) air from outside the system, as in the prior art et al. may be the case with the use of vacuum pumps. In addition, drying effects are avoided, since in a closed system no or little removal of stimulation-promoting fluid, such as body fluid takes place.

Furthermore, the pressure field generating device according to the invention due to the simple structure has the advantage of increased hygiene and improved cleaning ability. In this case, the present invention avoids valves or pumps / compressors with potential dead spaces and points not to be cleaned. Thus, the pressure field generating device according to the invention is easy to clean. For example, a cleaning of the stimulation device can be carried out in a simple manner by filling a cleaning liquid into the first chamber and activating the pressure field. Alternatively, the second chamber may be arranged interchangeably, which also facilitates the cleaning of both chambers. Furthermore, the chambers according to the invention and the connecting element of the pressure field generating device can be made in one piece, wherein these consist for example of a single plastic molded part (for example rubber). As a further alternative, the first chamber, the second chamber and the connecting element can be made in one piece.

In addition, the construction according to the invention leads to the avoidance of complex fluidic elements, such as e.g. Valves, which leads to a simplification of the production.

Furthermore, the stimulation device according to the invention has a drive unit, which the Volume of the first chamber changed such that over the connecting element in the second chamber, a pressure field is generated, which serves to stimulate the erogenous zone, and a control device, which controls the drive unit.

The transported between the chambers medium is limited in principle by its volume to the maximum volume of the first chamber. In addition, the volume transported through the maximum possible change in volume, which is caused by the drive unit, be further limited constructive.

As a result, the maximum positive or negative pressure that the stimulation device can build up in the second chamber is limited due to the dimensioning of the components of the pressure field generation device and the drive. In particular, the maximum positive or negative pressure can be limited to a level that minimizes or precludes a risk of injury to the skin areas to be stimulated. For example, a safety valve which is customary in the state of the art or a manual intervention of the user in the stimulation process, for example an opening of a release valve, is therefore unnecessary.

Furthermore, the time variation of the pressure field or the modulation of the pressure field is largely automatically controlled by the control device. Thus, in the control device, the modulation of the pressure field, such as intensity, time course or sequence, be pre-stored. The temporal change of the pressure field may preferably have regular or recurring (stimulation) patterns, for example pulses having a predetermined clock or regularly alternating pulse sequences. In this way, the interaction of the user with the stimulation device according to the invention can be limited to the switching on and off and the selection of the stimulation pattern, while the stimulation device automatically executes the preferred stimulation pattern. Thus, according to the invention, the application complexity of the stimulation device is low, especially in comparison to the conventional (medical) vacuum stimulation devices. Alternatively or additionally, the user may individually configure the stimulation patterns of the stimulation device during or before operation.

In addition, according to the invention, at least one extension is provided in the stimulation device. This extension can be used on the one hand as a handle to keep the stimulation device simple and comfortable, and on the other hand, the extension can also be used as a direct or stimulating means for insertion into the human body or for placing on the human body.

When the appendage is introduced into the human body, it serves to directly stimulate the affected body part. This complements the indirect stimulation effect of the pressure field generation device. Thus, simultaneous or alternating direct and indirect stimulation of several erogenous zones may take place. For example, the extension can be introduced into the female vagina, while at the same time or alternately a stimulation of the clitoris by means of the pressure field according to the invention can take place. Accordingly, the inventive principle of combined direct and indirect stimulation can also be applied to other body parts or their erogenous zones. For example, the appendix can be placed on the clitoris of a woman, while the pressure field generating device stimulates the clitoris of another or the same woman.

Thus, the stimulation device with extension of only one person or even two different persons can be used to stimulate several erogenous zones.

The combination of direct and indirect stimulation leads to an improvement of the stimulation effect and to a versatile applicability of the stimulation device. By means of the stimulation device according to the invention with an extension, there are also other, alternative varieties in the sexual act.

Thus, according to the invention, a stimulation device with several cumulative orgasm- or stimulation-triggering effects is provided, which is suitable for the stimulation of several erogenous zones, in particular the female clitoris. Next device is provided which avoids drying out of the erogenous zones to be stimulated, is hygienic and avoids habituation effects.

According to one embodiment of the invention, the extension of the pressure field generating device is movable, for example connected by means of a joint at one end of the extension. Thus, the stimulation device can be adapted to the particular anatomy of the human body and to its use. For example, the appendage may be inserted into the female vagina to thereafter adjust the angle between the pressure field generator and the appendage such that the aperture of the second chamber can be accurately placed over the clitoris. Consequently, the body region between the clitoris and the vagina is stimulated from both sides, with the effects of direct and indirect stimulation mutually reinforcing each other.

If the extension is used as a handle for holding the stimulation device, the angle between the handle and the opening of the second chamber can be adjusted according to the preferences of the user of the device.

According to one embodiment of the invention, the extension is a stimulation means, which is shaped so that one can introduce the extension for direct stimulation in the human body, for example in the vagina. In this case, the extension is preferably designed in the form of a dildo. In particular, sharp edges are avoided. Thus, the extension is preferably designed such that it can be easily inserted into body openings, and / or remains inserted in this.

According to one embodiment of the invention, the extension is an elongated, lens or pillow-shaped body, which is adapted such that the extension can be easily inserted into the female vagina. This improves the direct stimulation effect.

According to one embodiment of the invention, the extension is attached to the pressure field generating device such that the stimulation device is configured uniformly. Uniform means in this case in particular that the stimulation device with extension and pressure field generating device is designed as an integrated, coherent device. Preferably, the transitions between extension and pressure field generating device are designed here seamlessly. This improves the hygiene and the operability of the stimulation device.

According to a development of the invention, the extension has a vibration device. This vibration device can be actuated such that the extension, as is known in electromechanically operated dildos, vibrates. The vibration can either be activated independently of the other parts of the stimulation device, or else the vibration can be controlled by means of the control device, which then also controls the drive unit of the pressure field generation device. Preferably, the vibration may be controllable in a conventionally known manner in terms of strength, duration and sequence. The vibration enhances the direct stimulation effect.

According to a further aspect of the invention, a system with the stimulation device according to the invention is proposed according to the independent system claim, which has a remote from the stimulation device remote control device, wherein the control device of the stimulation device is remotely controlled by the remote control device. Thus, a conventional wireless (for example, via wireless) or wired remote control can be used to remotely control the modulation of the stimulation device or its activation by another user.

According to a further aspect of the invention, methods for stimulating body parts, in particular the clitoris, are proposed below. The associated advantageous effects and effects are explained in detail above with respect to the pressure field and the extension.

A further aspect of the invention is a method for stimulating erogenous zones, in particular the clitoris, for sexual pleasure and not for medical therapy, comprising the following steps:
Inserting an appendage into a human body; and
Forming a pressure field directed to a body part; and
Modulating the pressure field with a pattern of under and over pressures, with respect to a reference pressure, preferably the normal pressure.

Another aspect of the invention is a method for stimulating erogenous zones according to the previously mentioned method, wherein
the stimulation effect is influenced individually by the modulation of the pressure field by means of a control element.

Another aspect of the invention is a method for stimulating erogeous zones according to a method described above, wherein
the modulation is pulsed.

A further aspect of the invention is a method for stimulating erogenous zones, preferably the clitoris, for sexual pleasure and not for medical therapy, comprising the stimulation device according to one of the attached claims relating to the stimulation device, comprising the following steps:
Inserting the extension into a human body; and
Placing the second chamber over the body part, preferably over the clitoris;
Forming a pressure field directed to the body part;
Modulating the pressure field with a pattern of under and over pressures, relative to normal pressure;

Another aspect of the invention is a method for stimulating erogenous zones according to the method described above, wherein
the extension vibrates after insertion.

According to a further aspect of the invention, the use of the stimulation device according to the invention as a sex toy for stimulation of the female clitoris is proposed. As explained above, the female clitoris is a particularly sensitive erogenous zone of the woman, which is why the inventive use of an indirect massage in combination with a negative pressure stimulation for this body part for stimulation to orgasm appears particularly advantageous.

In the present invention, the methods for stimulating erogenous zones are for sexual pleasure, and thus the methods are for non-medical, for example, therapeutic, purposes.

The above-described features and functions of the present invention, as well as other aspects and features, will be further described below with reference to a detailed description of preferred embodiments with reference to the accompanying drawings.

Referring to the 4 . 5 and 6 Hereinafter, the structure and function of a first aspect of the pressure field generating device will be described 2 the stimulation device 1 explained in more detail.

4 shows the pressure field generating device 2 in a first state, wherein the second chamber 4 on the skin area to be stimulated or the body part 11 is attached. The first state of the pressure field generation device 2 is by a neutral deflection of the first chamber 3 characterized, that is, there is no external force, for example from the drive unit, to the first chamber 3 , Here, the volume V1 of the first chamber is the standard volume of this chamber 3 ,

The body part to be stimulated 11 is a skin area of the body, here exemplified a particularly sensitive erogenous zone, the clitoris 12 , is shown. Thus, the application of the present invention is not to the female clitoris 11 limited, but the stimulation device 1 can be applied to all parts of the body or erogenous zones (for example, the inner thighs, loins, neck, nipples, etc.), which can be stimulated by means of media or air pressure massage and / or negative pressure.

The second chamber 4 forms by placing on the body part to be stimulated 11 a to the exterior of the pressure field generating device 2 largely or completely closed chamber, which only via the connecting element 5 communicating with the second chamber, the edges of the chamber 4 ideally close to the surface of the body part 11 to lock. This creates two communicating chambers 3 and 4 , wherein in volume change one of the chambers 3 or 4 a corresponding pressure equalization between the chambers 3 and 4 over the connecting element 5 he follows.

A wall 31 the first chamber 3 is by means of a holder 32 fixed. The holder 32 is in turn on the housing 8th attached. On the bracket 32 is still the wall 41 attached to the second chamber. Two aligned openings in the wall 41 the second chamber and the holder 32 together form the connecting element 5 which is the first chamber 3 and the second chamber 5 combines. Here are the wall 31 , the holder 32 and the wall 41 preferably glued to each other media or airtight. Alternatively, these can also be used together (for example with the aid of sealing areas between the housing 8th and the respective part) press-fit or bolted. Also the holder 32 can with the case 8th for example, glued or screwed.

The wall 31 the first chamber 3 preferably consists of a flexible, media or airtight material, such as rubber. The holder 32 preferably consists of a rigid plastic, which is also impermeable to media or air. The wall 41 the second chamber is preferably made of a flexible, skin-friendly material, for example silicone or rubber.

5 shows the pressure field generating device 2 from 4 in a second state, again the second chamber 4 on the body part to be stimulated 11 is attached. The second state is characterized in that one on the first chamber 3 acting force A is an expansion of the chamber 3 causes. In detail, in this embodiment, the force A pulls the wall 31 the first chamber 3 in one direction, that of the second chamber 4 is directed away.

This increases the volume V2 of the chamber 3 , ie, V2> V1. To the resulting pressure difference between the chambers 3 and 4 now the medium or air flows from the second chamber 4 in the first chamber 3 ,

Assuming that in the first state of the in the chambers 3 and 4 If the present pressure corresponds to the currently prevailing external reference pressure (for example, the air pressure), then the present total pressure in the second state will be lower than the external reference pressure. This negative pressure is designed so that it is preferably lower than the usual systolic blood pressure in the blood vessels of the body part 11 , This increases the blood flow in this area and the clitoris 12 is better perfused in the second state.

6 shows the pressure field generating device 2 in a third state, again the second chamber 4 on the body part to be stimulated 11 is attached. The third state is characterized in that one on the first chamber 3 acting force B a volume reduction or compression of the chamber 3 causes. In detail, the force B in its direction is opposite to the direction of the force A and deforms the wall 31 the first chamber such that the resulting volume V3 of the chamber is smaller than the volume V1. The compression of the chamber 3 causes an overpressure in the chamber 3 , which by a media or air flow through the connecting element 5 in the direction of the second chamber 4 is compensated.

This media flow is now through the orientation of the opening 51 and / or the connecting element 5 preferably on the body part to be stimulated 11 , especially on the glans of the clitoris 12 , directed. The indirect (pressure) massage according to the invention is carried out by the on the body part 11 flowing medium. Here is the size of the opening 51 dimensioned such that these in relation to that in the first chamber 3 displaced volume is small enough to sufficiently accelerate the medium for a noticeable massage effect.

Next, the type of flow can not only be determined by the size and orientation of the opening 51 be influenced advantageously, but also by the internal configuration of the connecting element. For example, helical grooves in the connecting element 5 cause a swirl of the flow according to the invention, wherein the flow profile of the flow unfolds a "softer" or more turbulent effect on the body part to be stimulated. Alternatively, this can be in the second chamber 4 resulting pressure field using multiple openings 51 adapted according to the application.

In the in the 4 to 6 The arrangement shown is advantageous in that it is hygienically unproblematic (for example, due to the avoidance of dead spaces) and easy to manufacture. For example, there are no valves or other openings in or on the first chamber 3 required.

7 shows a second aspect of the present invention with an alternative construction of the pressure generating device 2 , So can the walls 31 and 41 the first and second chambers 3 and 4 interlock with each other so that they as well as in the first aspect of the construction of the pressure generating device 2 two communicating chambers with a connecting element 5 form. This eliminates a separate holder, while the second chamber 4 is interchangeable. In addition, the connecting element 5 integral or integral with the wall 41 the second chamber 4 be designed. An exchangeable chamber 4 has the advantage that in this way different, adapted to the respective body part shapes of the chamber 4 can be used (a more detailed explanation can be found later), without the entire stimulation device 1 to have to exchange. Alternatively, the second chamber 4 also on the housing 8th be attached pluggable (not shown). The wall 31 the first chamber 3 For example, with the case 8th glued or screwed.

Also, as in 7 represented by the dashed line and the double arrow C in more detail, the expansion and the compression of the first chamber 3 be effected by a force acting perpendicular to the axial direction of the connecting element 5 lies. Basically, by the drive unit 5 directly or indirectly to the first chamber 3 applied force from any direction. Decisive here is just that volume first chamber 3 through the drive unit 6 can be enlarged and reduced.

8th shows a third aspect of the invention with a one-piece construction of the pressure field generating device 2 , It can be used as a material of the chambers 3 and 4 an elastic material, for example silicone or rubber, are used. The advantage here is that possibly hygienic critical column can be avoided and the production cost is lower. Also in this case, the pressure field generating device 2 with the housing 8th glued or screwed. A change in the volume of the first chamber 3 takes place here in an analogous manner, as in connection with 7 described.

9 shows a fourth aspect of the invention with an alternative construction of the pressure field generating device 2 , Here are the second chamber 4 , several fasteners 5 , as well as sections of the wall 31 the first chamber 3 integrally formed. Alternatively, the pressure field generating device 2 while preserving the geometric model of 9 in a similar way as in 4 or 7 also shown to be constructed in two or more pieces of individual parts.

The volume change of the first chamber 3 takes place here in a manner similar to the piston pump, but missing here any existing valves. This is how a piston works 63 by the drive unit, for example an electric motor or an electromagnet, in the directions of the double arrow D reciprocated. This type of drive has the advantage that the volume of the first chamber 3 can be easily reduced to zero or approximately zero, and so the first chamber 3 almost completely emptied.

The embodiment of the connecting element 5 with multiple channels 52 and openings 51 leads to a distribution of the pressure field over several concentration points. While the configuration of the connecting element 5 with only one channel, as related to 6 described, leading to the formation of a highly concentrated media or air flow towards a target area, can in the in 9 shown embodiment of the connecting element 5 the media or air flow to several target areas are distributed. For example, the clitoris 11 be blown not only on his glans, but evenly from several sides. This distribution of airflow concentration across multiple areas may help, depending on the application to avoid overstimulation and / or to help increase the stimulation area.

The 10a to 10c show a fifth aspect of the invention with (partial) cross sections of a construction of the pressure field generating device 2 with a bending element 64 as a drive to change the volume of the first chamber 3 , The bending element 64 For example, it may be a conventional piezoelectric bending element that deforms or flexes upon application of a voltage. In this aspect of the invention, the wall is 31 the first chamber 3 rigid or rigid, while the bending element 64 suitably on the sides of the first chamber 3 is fitted. The transition points between the bending element 64 and the wall 31 sealed (for example, elastically bonded). In this construction, the drive for the pressure field generating device 2 already integrated into this and it eliminates an external drive. For example, eliminates an electric motor with an eccentric. As a result, possibly disturbing natural oscillations due to the eccentric movement of the stimulation device can be reduced.

In detail shows 10a the pressure field generation device 2 with the bending element 64 in neutral position. Thus, the volume of the first chamber 3 with the bending element 64 in neutral position the standard volume. 10b shows the first chamber 3 with an excited and subsequently outwardly bent bending element, which is why the volume of the first chamber 3 is enlarged; and in consequence prevails in the pressure field generating device 2 a negative pressure. 10c shows a comparison to 10b oppositely excited bending element of the first chamber 3 , which is why the volume of the first chamber 3 is reduced; and in consequence prevails in the pressure field generating device 2 an overpressure.

11 shows a second embodiment of the invention with a spatially separated arrangement of the chambers 3 and 4 the pressure field generating device 2 , Here are the chambers 3 and 4 over an extended connecting element 5 connected, which may be a longer flexible hose or even a rigid tube. For example, the length of the connecting element 5 0.5m. This makes it possible for the housing 8th to hold in one hand while the other hand holds the second chamber 4 on the body part to be stimulated 11 holds; or you can the housing 8th just put aside, while the user only the second chamber 4 holds in hands. Alternatively, the extension 140 be introduced into a body part, wherein it is no longer necessary that the stimulation device 1 held in the hand.

The 12a) to 12f) show different bottom and side views of other aspects of the second chamber 4 of the present invention. In detail shows 12a) a bottom view of a circular second chamber 4 with a centrally located opening 51 ; 12b) a bottom view of a triangular second chamber 4 with a centrally located opening 51 ; 12c) a bottom view of an oval second chamber 4 with a centrally located opening 51 ; and 12d) a bottom view of an approximately eight-shaped second chamber 4 with two openings arranged offset to the middle 51 , 12e) further shows a side cross-section of a second chamber according to the invention 4 , wherein the second chamber 4 additionally an extended contact area 43 to the skin or a support part 43 to the (Ab-) sealing function of the second chamber 4 to improve the skin. The extended contact surface 43 may also have grooves or projections that improve the sealing function even further. 12f) shows a side cross-section of a second chamber 4 with several separate connecting elements 5 and an extended contact area due to the support member 43 ,

So can the shape of the second chamber 4 basically be adapted to the anatomy of the erogenous zone to be stimulated. Here is the shape of the chamber 4 from 12a) for example, adapted to the round shape of the breast, while the shape of the chamber 4 of the 12c) better adapted to the shape of the female vulva. Further determines the shape of the second chamber 4 also the expression of the pressure field according to the invention. So determines the size of the second chamber 4 in relation to that of the first chamber 3 displaced volume, the height of the achievable under- or overpressure. Next can about the proximity of the opening 51 of the connecting element 5 to the skin area to be stimulated, the intensity of the massage effect according to the invention can be determined thereon. With several openings 51 , see. 12d) , the massage effect can also be spread over several areas. For example, the clitoris can be less stimulated directly on the very sensitive clitoris (cf. 12e) ), but reinforced on the clitoris surrounding areas to avoid over-stimulation of the clitoris.

13 FIG. 12 is a block diagram showing an example of a functional construction of an embodiment of the present invention including a controller. FIG 7 , a drive unit 6 , a lighting 9 , an on / off switch 74 , Controls 71 , a battery 76 and an external power supply 73 ,

In particular, the control device controls 7 the excitement of the drive unit 6 For example, the size of the deflection, the frequency, the modulation, etc.

Optional control elements 71 are used to set the operating mode of the device, ie the setting of the modulation pattern of the pressure field. The controls 71 For example, they can be designed as at least one push-button, as at least one rotary switch, or as at least one touch-sensitive switch. Next, the controls 71 an optical feedback for actuation, for example, by means of integrated into the switch light emitting diodes (LED) deliver.

An optional display 72 is used to inform the user about the device status and / or the setting state. The ad 72 For example, it can be configured from a plurality of light-emitting diodes or as an LCD display.

The drive unit 6 can now be chosen by the user of the stimulation device 1 via the controls 71 be driven in accordance with this prestored stimulation pattern in its excitation. The stimulation patterns of the pressure field can optionally also be individually created and stored by the user via the control elements.

A socket (not shown) may be external to the stimulation device 1 Serve via an external plug, which is connected for example to an external power adapter.

The dashed line indicates the reference pressure, for example the currently prevailing atmospheric pressure, which is outside the pressure field generating device (FIG. 2 ) is available. Will the second chamber 4 now on the body part to be stimulated 11 is set, the initially prevailing ambient pressure of the pressure field generating device ( 2 ) maintained approximately. Now it is assumed that the second chamber 4 is placed on the body part to be stimulated largely tightly. After activation of the stimulation device, the drive unit 6 from the controller 7 triggered or energized according to a pre-stored stimulation pattern. Correspondingly, the volume of the first chamber will be 3 and thus the total pressure in the pressure field generating device 2 change, with the pressure changes are modulated to the reference pressure. This in 14a) The pressure or stimulation pattern shown by way of example develops a pulsed, regular pressure field. In phases of increasing the pressure, the erogenous zone to be stimulated is blown or massaged, while in periods when it is under negative pressure it circulates the blood of the body part 11 For example, the clitoris is promoted. Thus, according to the invention, periods (In 14a) with I), in which there is a negative pressure, while the clitoris is massaged indirectly indirectly.

14b) shows three examples of alternative stimulation patterns. Thus, in the area marked II), a pulsed stimulation pattern with high amplitude is shown. In the area marked III) a pulsed stimulation pattern with low amplitude is shown. Furthermore, in the region marked with IV), an irregular or asymmetrical stimulation pattern is depicted in the temporal sequence and in the amplitude. The patterns can be varied according to physical effect / application and according to individual wishes.

14c) shows another example of an alternative stimulation pattern. Thus, the amount of pressure can increase over time to accommodate the user's state of excitement.
