Description

Stimulation device with extension

Technical Field

The invention relates to a stimulation device with an attachment for a sexually sensitive belt, in particular for the clitoris, a system with a stimulation device and a method for stimulating a body part.

Background

Various aids may be used to stimulate the somatosensory bands of a person's body. For example, vibrators are used to apply stimulation to a particular area of skin by direct contact. These aids include stimulation aids for insertion into the body of a person, such as a dildo.

Direct stimulation of the clitoris, for example with a clitoral massage vibrator, is often problematic. The clitoris is usually the most sensitive sexually sensitive band of women. The entire clitoris is highly innervated, making it particularly touch-sensitive and responsive to sexual stimulation. In this connection, the pedicles where the nerve cords of the two lower limbs meet should be particularly emphasized. Thus, on the one hand, frequent application of the clitoral massage vibrator to direct stimulation results in habitual effects or conditioning effects of the stimulated erogenous zone, while on the other hand, the first application of such a device may require some practice or familiarity. In addition, indirect stimulation of the female sexual sensory band may be insufficient or enhanced stimulation may be desired.

Further, medical studies conducted in 2006 identified the female clitoris as a clear starting point for female orgasm, and the different sensory qualities of clitoris and vaginal orgasm were first demonstrated in neurological terms. Thus, both clitoris and vagina can reach orgasm.

Further, the sensitivity of a human's sexually sensitive bands, such as the clitoris, inner and outer labia, or nipple, varies widely from one individual to another. Furthermore, the sensitivity of the corresponding band may vary significantly from one situation to another or even during sexual activity. Still further, it is often desirable to provide rapid and significant stimulation of different sexually sensitive bands.

Various forms of direct and indirect stimulation, such as vacuum pumps and dildo, are common practice.

For indirect stimulation of the erogenous zone, in particular the clitoris, conventional vacuum devices are used to stimulate the erogenous zone of the person concerned, but without direct contact with the main area to be stimulated. Thus, for example, vacuum pumps for the major or minor female sexual organs are known, which typically have a suction cup for placement on the appropriate area and a manual pump. The negative pressure exerted by this type of device on the clitoris creates a negative pressure, typically below the systolic pressure, for example in the clitoris itself. This pressure differential causes the clitoris to enlarge and/or stimulate blood flow in the affected area. This vascular clitoral engorgement is used to promote desire by increasing sensitivity as well as by visual and tactile manipulation. Improved blood circulation also results in increased secretion of vaginal moisture, which makes the stimulation more pleasant. However, manual operation of manual pumps is often cumbersome or annoying. Furthermore, the long term or uninterrupted application of negative pressure with the device category may also lead to habitual effects which in the long term limit the effectiveness of the device.

Electrically driven vacuum pumps are also increasingly being used instead of manually operated vacuum pumps. As an example of an electrically driven vacuum pump, WO 2006/058291 a2 discloses an apparatus for sexual therapy, wherein the device comprises a tubular suction chamber for the clitoris, an electrical vacuum source (vacuum pump) and a plurality of airflow openings. The operation of the vacuum pump creates a continuous flow of air or exchange of air in the chamber, in the region of the clitoris. This has the adverse effect that vaginal moisture, which is increased by negative pressure, is discharged by suction, thereby having a drying effect on the irritated skin portion. Likewise, the exhausted humid air causes contamination of the vacuum devices, such as vacuum pumps, fluidly downstream. Such devices with vacuum pumps can be problematic from a hygienic standpoint, as the vacuum pumps and associated valves or vent components often have dead spaces and/or are difficult to clean. Still further, the device is used to treat blood vessels in the clitoris, and not to provide stimulation up to orgasm.

US 6464653B 1 discloses a treatment device and method for creating clitoral engorgement with the aid of a vacuum created by a vacuum pump to help treat clitoral disorders such as incontinence. A control valve or regulator, suitably covered with a finger, is used to manually adjust or change the vacuum level in the suction chamber. This requires the attention of the user and may be annoying or distracting in some cases. Such a relatively complex device with additional valves also has drawbacks with regard to hygiene and dehydration as mentioned above, and furthermore, the device is used for long-term therapeutic purposes rather than for short-term sexual stimulation.

Therefore, the prior art devices have the common disadvantage that the complexity of the means for generating negative or positive pressure may be high and the devices may have problems in terms of hygiene. Furthermore, there is a problem of making it easy to operate the device, wherein holding the device is often uncomfortable and/or the device needs to be used to.

Still further, the prior art devices have a further common disadvantage in that habituation effects occur in the event of repeated application of negative pressure for a long period, continuously or frequently.

Another disadvantage of some of the previously described vacuum devices is that firstly the negative pressure must be limited by a control valve or vacuum pump and secondly the negative pressure should be released by manually opening 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 device incorrectly, there is a risk of injury in some cases.

Disclosure of Invention

Therefore, in view of the above-mentioned problems, it is an object of the present invention to provide a stimulation apparatus having a simple configuration, easy and safe to use, and having a remarkable stimulation effect.

The object of the invention is achieved by a stimulation device as claimed in claim 1. Advantageous developments and embodiments are the subject matter of the further independent and dependent claims.

According to the invention, the pressure field generating device of the stimulation device has at least one first chamber, at least one second chamber with at least one opening for placing on a body part or on a sexually sensitive belt, and at least one connecting element connecting the first chamber to the second chamber.

This embodiment of the chambers according to the invention, which are in fluid communication by means of at least one connecting element, allows to simply generate a pressure field in the second chamber, which is temporarily directed at the area of the skin to be stimulated, by varying the volume of the first chamber.

In the context of the present invention, a pressure field is a medium pressure field that is variable over time and has a temporary positive pressure and a temporary negative pressure, the negative pressure being a medium pressure that is lower than a reference pressure and the positive pressure being a medium pressure that is higher than the reference pressure. As a result, the medium flows to and fro in the pressure field according to the invention. Preferably, therefore, an (to a large extent) intermittent exchange of the medium may occur.

The medium is typically gaseous, preferably air, but may for example alternatively or additionally be a liquid medium such as water or a commercially available lubricant. For example, the chamber according to the invention may be filled with a lubricant before the stimulation device is employed. This also allows stimulating the respective area of the skin with a suitable skin friendly liquid instead of air, which may be desirable according to the personal preferences of the user. As a further example, the stimulation device may also be used underwater with water as the medium (e.g. in a bathtub). In this case, the stimulation device is in a waterproof form.

When application is started (i.e. before the stimulation device is placed on the skin area to be stimulated), the reference pressure is typically the atmospheric pressure acting on the stimulation device. In a preferred application of the stimulation device with air, the reference pressure is the currently prevailing air pressure or normal pressure. For example, when the device is applied under normal standard conditions, the reference pressure may be approximately 1 bar, from after application of the device, the negative pressure according to the invention may be, for example, 0.7 bar and the positive pressure according to the invention may be, for example, 1.3 bar.

The pressure field according to the invention is used on the one hand to stimulate the blood circulation of the skin region to be stimulated, while on the other hand indirectly massaging said skin region. This combines two beneficial effects. The increased blood circulation makes the relevant person's erogenous zone more sensitive, while also producing a massaging effect for stimulating the erogenous zone, for example for sexual arousal up to orgasm. The massaging action is generated by the kinetic energy of the medium flowing from the first chamber, through the connecting element, against the surface of the skin area to be stimulated. In this way, the massaging action formed by the pressure field is generated indirectly, i.e. without the skin portion to be stimulated being in direct contact with an entity such as a vibrator.

With regard to an exemplary application of a time-variable pressure field to the clitoris in accordance with the present invention, the pressure field mimics the stimulation that typically occurs during coital streaming. Likewise, sexual activity during this period may also produce different clitoral stimulation. This is therefore a realistic simulation of the natural behaviour of sexual intercourse, wherein medical findings confirm that the application of a stress field according to the invention causes neither habituation effects nor addiction. In particular, this is due to the alternating application of negative and positive pressures (or indeed due to the discontinuous application of only one type of pressure).

Still further, the maximum applicable pressure is generally limited by the maximum load that can be loaded on the skin area to be stimulated. Thus, for example, a too high negative pressure has the risk of painful damage, in particular in the sexually sensitive bands. Stimulation devices that operate only with negative pressure are typically limited to this maximum value in their mode of operation. In contrast, according to the present invention, the combination of positive and negative pressure forms an extended operating range of the stimulus-induced pressure field or effect, since the operating range of pressure can now be used to a maximum in both the positive and negative ranges.

The orientation of the at least one connection element towards the skin area to be stimulated allows a direct working of the pressure field which is decisively influenced by the configuration of the at least one connection element and the at least one opening from the connection element to the second chamber, so that the pressure field is adjustable depending on the application of the stimulation device. Thus, the at least one opening of the connecting element may be located opposite, preferably directly opposite, the body part to be stimulated. For example, a connecting element in a stimulation device intended for the clitoris may have a single passage opening between the first and second chambers that has a nozzle effect on the clitoral head. Alternatively, if a relatively large skin area is to be stimulated, the at least one connection element may comprise a plurality of, for example four, passage openings between the chambers.

Furthermore, after placing the second chamber, which is not completely or partially open, on the skin area to be stimulated, a closed system of medium or air flows is formed in the pressure field generating device. Thus, the medium or air is moved back and forth between the chambers without interruption, while at least an exchange with medium or air from outside the system is largely avoided. Thus, the first chamber is preferably exclusively connected to the second chamber by or by means of the connecting element. Thus, the first chamber has no connections other than the connection with the second chamber; for example, there is no direct connection between the first chamber and the environment surrounding the apparatus through a pressure valve or an air exhaust flow passage.

For example, the temperature of the air in the flow system according to the invention is quickly adjusted to the skin temperature, while avoiding an annoying supply of new (possibly cold) air from outside the system, as is the case especially when using vacuum pumps of the prior art. Furthermore, because little or no removal of stimulus-promoting fluid, such as bodily fluids, is done in a closed system, the drying effect is avoided.

Furthermore, the pressure field generating device according to the invention has the advantage of better hygiene and improved cleaning capacity due to the simple construction. Here, the invention avoids the valve or pump/compressor having potentially dead spaces and places that cannot be cleaned. Therefore, the pressure field generating device according to the present invention is easy to clean. For example, the stimulation device may be cleaned in a simple manner by filling the first chamber with a cleaning agent and activating the pressure field. Alternatively, the second chamber may be arranged to be replaceable, which also simplifies cleaning of both chambers. Furthermore, the chamber according to the invention and the connecting elements of the pressure field generating device may be manufactured in one piece, wherein they are for example made of a single plastic molded part (e.g. rubber). As a further alternative, the first chamber, the second chamber and the connecting element may be made in one piece.

Furthermore, the construction according to the invention has the result that complex fluid engineering elements, such as valves, are avoided, which leads to a simplified manufacture.

Furthermore, the stimulation device according to the invention has a drive unit which changes the volume of the first chamber such that a pressure field is generated in the second chamber by the connecting element, which pressure field is used for stimulating the sexual sensory strip, and a control device which activates the drive unit.

The principle of the invention means that the medium transported between the chambers is limited in volume to the maximum volume of the first chamber. Furthermore, as a result of its construction, the volume delivered can be further limited by the maximum possible volume change caused by the drive unit.

Thus, the maximum positive or negative pressure that the stimulation device can build in the second chamber is limited due to the size of the components of the pressure field generating means and the size of the driver. In particular, the maximum positive or negative pressure may be limited to an amount that minimizes or eliminates any risk of injury for the area of skin to be stimulated. As a result, safety valves common in the prior art or manual intervention by the user during the stimulation, for example opening a release valve, are for example considered unnecessary.

Furthermore, the variation of the pressure field over time or the modulation of the pressure field by the control device is controlled to a large extent automatically. Thus, the modulation of the pressure field, for example the intensity, the time profile or the time sequence, can be pre-stored in the control device. Preferably, the variation of the pressure field over time may have a regular or cyclic (stimulation) pattern, for example pulses at a predetermined cyclic rate or a regularly alternating pulse sequence. This allows the user's interaction with the stimulation device according to the invention to be limited by the switching on and off of the stimulation mode and the selection of the stimulation mode, although the stimulation device automatically executes the preferred stimulation mode. Thus, according to the invention, the complexity of using the stimulation device is low, especially when compared to conventional (medical) vacuum stimulation devices. Alternatively or additionally, the stimulation mode of the stimulation device may be configured separately by the user during or before operation.

Furthermore, according to the invention, the stimulation device is provided with (at least) one attachment. On the one hand, the accessory may be used as a handle for easily and comfortably holding the stimulation device, and on the other hand, the accessory may also be used as a direct stimulation aid for insertion into or indeed for placement on the body of a person.

If the accessory is inserted into a person's body, the accessory is used to directly stimulate the relevant body part. Thus, the accessory complements the indirect stimulating effect of the pressure field generating means. Thus, it is possible for multiple sexually sensitive bands to have direct and indirect stimulation occurring simultaneously or alternately. For example, the accessory may be inserted into a female vagina when clitoral stimulation may be performed simultaneously or alternately by means of a pressure field according to the invention. Thus, the principle of combined direct and indirect stimulation according to the invention can also be applied to other body parts or to the sexually sensitive bands of a body part. For example, the accessory may be placed over the woman's clitoris while the pressure field generating device stimulates the clitoris of another woman or the same woman.

In this way, the stimulation device with the attachment can be used by only one person or indeed by two different persons to stimulate multiple sexually sensitive bands.

The combination of direct stimulation and indirect stimulation leads to an improved stimulation effect and a multifaceted application of the stimulation device. Furthermore, it is further possible to use the inventive stimulation device with an attachment for an alternative type of sexual intercourse during sexual activity.

Thus, according to the present invention, there is provided a stimulation device having a plurality of cumulative orgasm effects or stimulation-induced effects and adapted to stimulate a plurality of sexual sensory cords, in particular the clitoris of a female. Still further, an apparatus is provided for avoiding dehydration of a sexually sensitive strip to be stimulated, which is hygienic and avoids habitual effects.

According to a development of the invention, the attachment is moved with the pressure field generating device connected, for example, by means of a joint at one end of the attachment. In this way, the stimulation device may be adapted to the anatomy of the body of the person in question and its use. For example, the accessory may be inserted into a female vagina, so that the angle between the pressure field generating device and the accessory is then adapted so that the opening of the second chamber may be accurately placed over the clitoris. Thus, the body area between the clitoris and the vagina is stimulated from both sides, mutually enhancing the effects of direct stimulation and indirect stimulation.

If the accessory is used as a handle for holding the stimulation device, the angle between the handle and the opening of the second chamber may be adapted to conform to the preferences of the user of the device.

According to a development of the invention, the accessory is a stimulating aid shaped such that the accessory can be inserted into a person's body, for example the vagina, for direct stimulation. In this case, the attachment is preferably in the form of a dildo. Here, sharpening corners is specifically avoided. Thus, the accessory is preferably in the form of: the accessory may be smoothly inserted into the body cavity and/or may also remain inserted into the body cavity.

According to a development of the invention, the appendage (140) is an elongated lenticular or pillow-shaped body adapted such that the appendage can be smoothly inserted into the woman's vagina. This improves the direct stimulation effect.

According to a development of the invention, the attachment is mounted on the pressure field generating means such that the stimulation device is uniform in form. Here, unified means in particular that the stimulation device with the attachment and the pressure field generating means takes the form of an integrated, adhesive device. Preferably, in this case, the attachment and the pressure field generating device merge seamlessly into one another. This improves the hygiene and operability of the stimulation device.

According to a development of the invention, the accessory has a vibration device. Such a vibrating device may be actuated to vibrate the attachment, as is known in the example of an electromechanically operated dildo. In this case, the vibration can either be activated independently of the other parts of the stimulation device, or indeed the vibration can be controlled by means of a control device which in this case also controls the drive unit of the pressure field generating means. Preferably, the vibration may be controlled in a conventional manner in terms of intensity, duration and sequence. The vibration enhances the direct stimulation effect.

According to a further aspect of the invention, according to the further independent claim 20, a system with a stimulation device according to the invention is proposed, which system has a remote control device arranged separately from the stimulation device, wherein the control device of the stimulation device is remotely controlled by the remote control device. This allows the use of a conventional wireless (e.g. by radio) or wired remote control to allow the stimulation device to be modulated or activated by other users with remote control.

According to a further aspect of the invention as claimed in claims 21 to 25, a method for stimulating a body part, in particular the clitoris, is proposed. The relevant advantageous effects are explained in more detail above with respect to the pressure field and the attachment.

According to a further aspect of the invention, as claimed in claim 19, the use of a stimulation device according to the invention as a sexual toy for stimulating the clitoris of a female is proposed. As explained hereinbefore, the female clitoris is a particularly sensitive erosensory band for women, which is why the use according to the invention of indirect massage stimulation in combination with negative pressure stimulation to the body part for stimulation up to climax appears particularly advantageous.

In the present invention, the method for stimulating the erogenous zone is used for sexual pleasure, and therefore the method is not used for medical treatment such as therapeutic purposes.

The above features and functions and further aspects and features of the present invention are further described below with the aid of the detailed description of preferred embodiments with reference to the attached drawings.

Detailed Description

A first embodiment will be described below with reference to fig. 1, 2 and 3. Fig. 1 shows a front view of a first embodiment of a stimulation device 1 according to the invention with the attachment 140 in a vertical position, while fig. 2 further shows a side view of the stimulation device 1 with the attachment 140 in an angled position, and fig. 3 shows a cross-section of the first embodiment of the stimulation device 1 according to the invention.

The first embodiment of the stimulation device 1 is preferably a portable electrical or small device having a housing 8, a pressure field generating means 2, an optional on/off switch 74 and an optional light 9.

The housing 8 preferably takes an ergonomic form such that the housing can be comfortably held in one hand and does not have sharp or pointed edges. Still further, the housing 8 may be made of a plastic material such as Polycarbonate (PC) or Acrylonitrile Butadiene Styrene (ABS). Furthermore, the gripping area or even the entire housing may be supplemented by or made of silicone with advantageous tactile properties. The housing 8 preferably takes at least a waterproof or splash-proof form, such as a protection grade IP 24. Further, the dashed lines in fig. 2 represent optional side edges of the housing 8.

An optional on/off switch 74 is used to activate and deactivate the stimulation device 1. The on/off switch 74 may for example be a button that turns the stimulation device 1 on or off when controlled, or a locking slide switch. Alternatively, it is possible to switch the stimulation device 1 on and off by remote control.

The pressure field generating device 2 of the first embodiment has a first chamber 3 inside the stimulation device 1, a second chamber 4 for placement on a body part 11 to be stimulated, and a connecting element 5 connecting the first chamber 3 to the second chamber 4.

The drive unit 6, for example an electric motor, drives the first chamber 3 through the shaft 61 and by means of the cam 62 (or alternatively by means of a connecting rod) so that the volume of the first chamber 3 varies according to the rotation of the shaft 61 of the drive unit 6. In this connection, it should be noted that in principle any actuator type that causes a deformation of the wall 31 of the first chamber 3 for a change in volume may be employed in the stimulation device 1. This may be performed, for example, hydraulically, pneumatically, piezoelectrically, mechanically or electromagnetically. Examples of this are described in more detail below.

The control device 7 activates the drive unit 6, the optional operating elements 71 and the at least one optional display 72. Here, the control device 7 and the drive unit 6 are powered, for example, by an internal battery 76 and/or an external power supply 73.

The stimulation device 1 further has at least one attachment 140. This attachment 140, which is preferably part of the housing 8, may optionally be displaced or angled relative to the housing part containing the pressure field generating device 2. Here, the accessory can be angled by means of the joint 141 or indeed rotated by means of the joint 141. The joint 141 may for example take the form of a plastically deformable plastic part, an adjustable joint or a hinge. Fig. 2 shows an example of the position of the angled appendage 140 relative to the section of the housing 8 of the stimulation device 1 that accommodates the pressure field generating means 2. Alternatively, the attachment may also take a rigid or non-movable form.

Preferably, the accessory 140 is a stimulating adjunct for insertion into a person's body, such as a vagina or other body orifice. Here, the attachment 140 is shaped as a conventional dildo, for example. Alternatively, the accessory may be configured such that it fits into the anatomy of another body orifice (e.g., the mouth) of a person. Furthermore, the accessory 140 may take the form that it may also be used as a handle for comfortably holding the stimulation device 1.

Further, the accessory 140 may optionally have a vibration device 142 that can be turned on and/or controlled. The vibration device 142 subjects the accessory to mechanical vibrations that support the direct stimulating effect of the accessory 140.

Optionally, the attachment 140 is mounted on a section of the housing 8 accommodating the pressure field generating device 2, such that the (entire) housing 8 of the stimulation device 1 takes a uniform form. In this way, the housing 8 forms an integrated impression, for example by means of flexible and/or seamless connecting elements of the housing 8. Alternatively, the housing 8 including the attachment 140 may have a silicon coating.

In a vertical or non-angled orientation of the accessory 140 (as shown in fig. 1), the stimulation device 1 may be comfortably held or actually inserted into the body orifice in a simple manner. If the appendage 140 is angled, for example after insertion (as shown in fig. 2), the opening 42 can thus be guided away from the body part 11 to be stimulated. At this angled position of the stimulation device 1, direct and indirect stimulation of at least one erotic band of the body may be performed simultaneously. In this case, the body part 11 to be stimulated is located between the attachment 140 and the pressure field generating device 2.

Still further, an optional lamp 9 may be provided on or in the housing 8. Here, the lamp 9 is preferably used to illuminate the interior of the second chamber 4. The light 9 may be switched on by the user or activated automatically when the stimulation device 1 is activated. Further, the lamp 9 may take the form of an energy-saving light emitting diode. The lamp may be used, for example, as a directional aid in the dark or as an additional visual stimulus for the user of the stimulation device 1.

With reference to fig. 4, 5 and 6, the construction and function of the first aspect of the pressure field generating means 2 of the stimulation device 1 will be described in more detail below.

Fig. 4 shows the pressure field generating device 2 in a first state, in which the second chamber 4 is placed on the skin area or body part 11 to be stimulated. The first state of the pressure field generating device 2 is characterized by a neutral deformation of the first chamber 3 (i.e. no external force acts on the first chamber 3, e.g. from the drive unit). Here, the volume V1 of the first chamber is the standard volume of the chamber 3.

The body part 11 to be stimulated is a skin region of the body, wherein a particularly sensitive sexually sensitive band, the clitoris 12, for example, is shown here. Thus, however, the use of the present invention is not limited to the female clitoris 11; instead, the stimulation device 1 can be applied to all body parts or sexually sensitive bands (e.g. the inner sides of the thighs, the lumbar region, the nape of the neck, the nipple, etc.) which can be stimulated by means of medium-or air-pressure massage and/or negative pressure.

Since the second chamber 4 is placed on the body part 11 to be stimulated, the second chamber 4 forms a chamber which is largely or completely isolated from the outside of the pressure field generating device 2 and which remains connected only to the second chamber by the connecting element 5, wherein the edges of the chamber 4 ideally form an air-tight envelope with the surface of the body part 11. The two communicating chambers 3 and 4 are produced in such a way that, in the event of a change in volume of one of the chambers 3 or 4, a corresponding pressure equalization takes place between the chambers 3 and 4 via the connecting element 5.

The wall 31 of the first chamber 3 is fixed by means of a holder 32. The holder 32 is in turn attached to the housing 8. Further, the wall 41 of the second chamber is mounted on the holder 32. The two mutually aligned openings in the wall 41 of the second chamber and the holder 32 together form a connecting element 5 connecting the first chamber 3 and the second chamber 4. In this arrangement, the wall 31, the holder 32 and the wall 41 are preferably joined to one another by gluing with a medium seal or an air seal. Alternatively, they may also be press-fitted or screwed to each other (for example with the aid of a sealing region between the housing 8 and the respective part). The holder 32 may also be joined to the housing 8, for example by gluing or screwing.

The wall 31 of the first chamber 3 is preferably made of a flexible medium-tight or air-tight material, such as rubber. The retainer 32 is preferably made of a rigid plastic material that is also media-tight or air-tight. The wall 41 of the second chamber is preferably made of a flexible, skin-friendly material, such as silicone or rubber.

Fig. 5 shows the pressure field generating device 2 of fig. 4 in a second state, in which the second chamber 4 is again placed on the body part 11 to be stimulated. The second state is characterized by: the force a acting on the first chamber 3 causes the chamber 3 to expand. Specifically, in this exemplary embodiment, the force a pulls the wall 31 of the first chamber 3 in a direction away from the second chamber 4.

This increases the volume of chamber 3, V2, i.e. V2 > V1. In order to equalize the pressure difference formed between the chambers 3 and 4, the medium or air now flows from the second chamber 4 into the first chamber 3.

Assuming that the pressure in the chambers 3 and 4 in the first state corresponds to the currently prevailing external reference pressure (e.g. air pressure), the overall pressure present in the second state will be lower than the external reference pressure. The negative pressure is set such that it is preferably below the usual systolic pressure in the blood vessels of the body part 11. Blood circulation in this region is thus increased and the clitoris 12 is better supplied with blood in the second condition.

Fig. 6 shows the pressure field generating device 2 in a third state, in which the second chamber 4 is again placed on the body part 11 to be stimulated. The third state is characterized in that the force B acting on the first chamber 3 causes a reduction or compression of the volume in the chamber 3. Specifically, the direction of force B is opposite to the direction of force a and deforms the wall 31 of the first chamber such that the resulting volume V3 of the chamber is less than the volume V1. The compression of the chamber 3 results in a positive pressure in the chamber 3, which is equalized by passing a flow of medium or air through the connecting element 5 in the direction of the second chamber 4.

The medium flow is now preferably directed towards the body part 11 to be stimulated, in particular towards the clitoris of the clitoris 12, by the orientation of the opening 51 and/or the connecting element 5. The indirect (pressure) massage according to the invention takes place due to the flow of medium onto the body part 11. In this case, the size of the opening 51 is set such that it is sufficiently small relative to the volume displaced in the first chamber 3 to sufficiently accelerate the medium for a perceptible massaging effect.

Still further, this type of flow is advantageously influenced not only by the size and orientation of the openings 51 but also by the internal configuration of the connecting element. For example, a helical groove in the connecting element 5 may cause a flow rotation according to the invention, wherein the flow distribution produces a "softer" or more turbulent effect on the body part to be stimulated. Alternatively, the pressure field generated in the second chamber 4 may be adjusted to suit the application by means of a plurality of openings 51.

The advantage of the device shown in fig. 4 to 6 is that it is problem-free from a hygienic point of view (since e.g. dead spaces are avoided) and simple to manufacture. For example, no valves or further openings are needed in or on the first chamber 3.

Fig. 7 shows a second aspect of the invention with an alternative configuration of the pressure field generating device 2. Here, the walls 31 and 41 of the first chamber 3 and the second chamber 4 may engage each other such that they form two communicating chambers with the connecting element 5, as in the first aspect of the construction of the pressure field generating device 2. Thus, no separate holder is required, while the second chamber 4 is replaceable. Furthermore, the connecting element 5 may take the form of a piece or an integral part with the wall 41 of the second chamber 4. The exchangeable chamber 4 has the advantage that in this way various shapes of the chamber 4 adjusted to the respective body part (which will be described in more detail below) can be used without the need to replace the entire stimulation device 1. Alternatively, the second chamber 4 may also be attached to the housing 8 by being pushed (not shown in more detail). The wall 31 of the first chamber 3 may be joined to the housing 8 by, for example, gluing or screws.

It is also possible that the first chamber 3 is expanded and compressed by a force acting perpendicular to the axial direction of the connecting element 5, as shown in more detail in fig. 7 by means of a dashed line and a double arrow C. In principle, the force exerted indirectly or directly on the first chamber 3 by the drive unit 5 can be exerted from any direction. The only decisive criterion here is that the volume of the first chamber 3 can be increased and decreased by means of the drive unit 6.

Fig. 8 shows a third aspect of the present invention with an integrated structure of the pressure field generating device 2. Here, an elastic material such as silicone or rubber may be used as the material of the chambers 3 and 4. The advantage here is that any suspicious gaps are avoided from a hygienic point of view and the manufacturing costs are reduced. In this case, the pressure field generating device 2 can also be joined to the housing 8 by gluing or screwing. The change in volume of the first chamber 3 here takes place in a manner similar to that described in connection with fig. 7.

Fig. 9 shows a fourth aspect of the invention with an alternative configuration of the pressure field generating device 2. The second chamber 4, the plurality of connecting elements 5 and a partial section of the wall 31 of the first chamber 3 are designed in one piece. Alternatively, the pressure field generating device 2 may also be constructed in two parts or more from a separate component, while maintaining the geometry of fig. 9 in a similar manner as shown in fig. 4 or fig. 7.

In this case the volume in the chamber 3 is changed in a similar way to a piston pump, although no valve of any kind is present in the chamber 3. Thus, the piston 63 is moved back and forth in the direction of the double arrow D by a driving unit such as a motor or an electromagnet. This type of drive has the advantage that: the volume of the first chamber 3 can be reduced to zero or approximately zero in a simple manner, allowing the first chamber 3 to be almost completely emptied.

The embodiment of the connecting element 5 with a plurality of flow channels 52 and openings 51 results in a distribution of the pressure field over a plurality of concentration points. Although the embodiment of the connecting element 5 with only one flow channel results in a highly concentrated medium or air flow over the target area, as described in connection with fig. 6, the embodiment of the connecting element 5 shown in fig. 9 allows a distribution of the medium or air flow over a plurality of target areas. In this way, the flow can be blown, for example, against the clitoris 11, not only over the clitoris head but also evenly against the clitoris 11 from multiple sides. Depending on the application, the concentrated distribution of the air flow to multiple regions may help avoid over-stimulation and/or help increase the stimulation area.

Fig. 10a to 10c show a fifth aspect of the invention with (partial) cross-sections of a configuration of the pressure field generating device 2 with a bending element 64, which bending element 64 acts as a driver for changing the volume of the first chamber 3. The flexure element 64 may be, for example, a conventional piezoelectric flexure element that deforms or bends upon application of a voltage. In this aspect of the invention, the wall 31 of the first chamber 3 takes a rigid or stiff form, while the curved element 64 is made suitable to fit against the side of the first chamber 3. The transition point between the bending element 64 and the wall 31 is in this case sealed (for example elastically joined by gluing). In this configuration, the driver for the pressure field generating device 2 is already integrated in the pressure field generating device and no external driver is required. For example, a motor with a cam is not required. This makes it possible in particular to reduce any disruptive natural resonance caused by the movement of the cam of the stimulation device.

Fig. 10a shows in detail the pressure field generating device 2 with the bending element 64 in a neutral position. Thus, the volume of the first chamber 3 with the bending element 64 at the neutral position is a standard volume. Fig. 10b shows the first chamber 3 even further with a curved element which is activated and thus curved outwards, for which reason the volume of the first chamber 3 increases; therefore, negative pressure prevails in the pressure field generating device 2. Fig. 10c shows the bending element of the first chamber 3 being excited in the opposite direction to fig. 10b, for which reason the volume of the first chamber 3 is reduced; therefore, positive pressure prevails in the pressure field generating device 2.

Fig. 11 shows a second exemplary embodiment of the invention with a spatially separated arrangement of the chambers 3 and 4 of the pressure field generating device 2. The chambers 3 and 4 are in this case connected by an extended connecting element 5, which may be a relatively long flexible hose or pipe, which may also be rigid. For example, the length of the connecting element 5 may be 0.5 m. This enables the housing 8 to be held in one hand while the other hand holds the second chamber 4 on the body part 11 to be stimulated; or the housing 8 may simply be placed aside while the user holds only the second chamber 4 in both hands. Alternatively, the accessory 140 may be inserted into a body part, in which case the stimulation device 1 no longer needs to be held in the hand.

Fig. 12a) to 12f) show various bottom and side views of further aspects of the second chamber 4 of the invention. In detail, fig. 12(a) shows a bottom view of the circular second chamber 4 with a central opening 51; fig. 12b) shows a bottom view of the triangular second chamber 4 with a central opening 51; fig. 12c) shows a bottom view of the elliptical second chamber 4 with a central opening 51; fig. 12d) shows a bottom view of the approximately 8-shaped second chamber 4 with two openings 51 arranged offset from the center. Fig. 12e) shows a side section of the second chamber 4 according to the invention even further, wherein the second chamber 4 additionally has an extended contact surface 43 or support portion 43 for the skin to improve the sealing function of the second chamber 4 against the skin. Furthermore, the extended contact surface 43 may have grooves or protrusions that improve the sealing function even further. Fig. 12f) shows a side section of the second chamber 4 with a plurality of separate connecting elements 5 and an extended contact surface formed by the support part 43.

Thus, the shape of the second chamber 4 may be adapted substantially to the anatomy of the sexually sensitive zone to be stimulated. The shape of the chamber 4 in fig. 12(a) for example adapts to the circular shape of the breast, whereas the shape of the chamber 4 in fig. 12(c) is more adapted to the shape of the female vulva. Further, the shape of the second chamber 4 also determines how the pressure field according to the invention is pronounced. Thus, the size of the second chamber 4 relative to the volume displaced from the first chamber 3 determines the level of negative or positive pressure that can be achieved. Still further, the proximity of the opening 51 of the connecting element 5 to the area of skin to be stimulated may also be used to determine the intensity of the massaging action according to the invention on said area of skin. The plurality of openings 51 (see fig. 12d) allows the massaging action to be distributed over a plurality of areas. Thus, for example, the clitoris may be less directly stimulated at the very sensitive clitoris (see fig. 12e)) but may be more stimulated at the area around the clitoris in order to prevent over-stimulation of the clitoris.

Fig. 13 shows a block diagram of an example of a functional configuration according to an embodiment of the present invention, which has the control device 7, the drive unit 6, the lamp 9, the on/off switch 74, the operation element 71, the battery 76, and the external power supply 73.

The control device 7, for example with a microcontroller or hard-wired, initially controls the supply of power to the stimulation device 1 to all consumers and optionally controls the charging and discharging process and/or battery management of the battery 76. In particular, the control device 7 controls the excitation of the drive unit 6, such as the magnitude of the deformation, the frequency, the modulation, etc.

An operating element 71 is optionally provided for setting the mode of the device, i.e. setting the modulation mode of the pressure field. The operating element 71 may, for example, take the form of at least one push button, at least one rotary switch or at least one touch-sensitive switch. Further, for confirmation purposes, the operating element 71 may emit optical feedback, for example by means of a Light Emitting Diode (LED) integrated in the switch.

An optional display 72 is used to inform the user of the device status and/or set conditions. The display 72 may, for example, take the form of a plurality of light emitting diodes or an LCD display. The displayed information may be, for example, the charging status of the optional battery or the current setting of the modulation mode.

Still further, the control device 7 may have a memory in which at least one modulation pattern or stimulation pattern (described in more detail in connection with fig. 14a) to 14 c)) is stored. The activation of the drive unit 6 can now be activated by the operating element 71 according to the previously stored stimulation pattern, depending on the selection made by the user of the stimulation device 1. The stimulation pattern of the pressure field can also be generated and stored by the user optionally and separately by means of the operating element.

A socket (not shown in detail) may be used to supply external power to the stimulation device 1, e.g. by means of an external plug connected to an external power adapter. In order to ensure that the stimulation device 1 is splash-proof, it is also possible, instead of a socket, to provide an electromagnetic induction transformer which allows power to be supplied to the stimulation device 1 without electrically conductive contacts. Preferably, furthermore, the stimulation device 1 has a battery for wireless operation, for example a nickel metal hydride battery (NiMH). Alternatively, a (relatively long) power cable may lead from the stimulation device.

Fig. 14a) shows a sequence over time of the overall pressure p in the pressure field generating device (2) when the pressure field generating device (2) is used for stimulation. The dashed line represents a reference pressure, such as the currently prevailing atmospheric pressure outside the pressure field generating device (2). If the second chamber 4 is now placed on the body part 11 to be stimulated, the initially prevailing ambient pressure remains approximately constant in the pressure field generating device (2). It is assumed that the second chamber 4 is placed on the body part to be stimulated such that the second chamber is largely air-tight. Once the stimulation device is activated, the drive unit 6 is activated or stimulated by the control device 7 according to the previously stored stimulation pattern. Thus, as the pressure variation is modulated onto the reference pressure, the volume of the first chamber 3 is changed, and thereby the overall pressure in the pressure field generating device 2 is changed. The pressure or stimulation pattern shown as an example in fig. 14a) produces a pulsed, regular pressure field. During the phase of pressure increase, air blows or massages the erogenous zone to be stimulated against it, however during periods of prevailing negative pressure, blood circulation in the body part 11, for example the clitoris, is facilitated. There is therefore a period according to the invention (designated I) in fig. 14a) during which the negative pressure prevails while the clitoris is being massaged indirectly at the same time.

Fig. 14b) shows three examples of alternative stimulation patterns. Thus, the region labeled II) shows a high amplitude pulsed stimulation pattern. The region labeled III) shows a low amplitude pulsed stimulation pattern. Still further, the region labeled IV) shows a stimulation pattern that is irregular with respect to the sequence over time and asymmetric in amplitude. The pattern may vary according to the action/application on the body and according to the desires of the individual.

Fig. 14c) shows a further example of an alternative stimulation pattern. Here, the intensity of the pressure may be increased over time in order to adapt to the state of excitement of the user.

The invention allows for further construction principles in addition to the embodiments already described. For example, different arrangements or configurations of the first chamber 3 may be combined with different embodiments of the second chamber 5 or the connecting element 5 as desired. For example, the first chamber 3 with driver in fig. 10 may be combined with the second chamber in fig. 12 f).

Although only one first chamber 3 is shown in all embodiments, it is also possible to provide two or more first chambers 3 which are then correspondingly driven simultaneously or with a time delay such that their volume is changed in order to build up a pressure field according to the invention.

Although in all embodiments only one opening from the first chamber 3 to the connecting element 5 is shown, it is also possible to provide a plurality of openings for the connecting element 5 or indeed a plurality of openings for a plurality of connecting elements 5 in the first chamber 3.

The stimulation device 1 may have a plurality of pressure field generating means 2. Thus, for example, two pressure field generating means may be provided in order to stimulate two sexual bands simultaneously.

The stimulation pattern according to the invention may differ from the patterns shown in fig. 14a), 14b) and 14c), provided that they have a sequence of positive and negative pressure over time. For example, a relatively permanent negative pressure may be constructed initially at the start of the device or after activation of the device (e.g. 3 minutes) in order to effectively increase blood circulation in the zone to be stimulated, followed by pulses of negative and positive pressure that slowly increase in amplitude.
