Description

The invention relates to a stimulation device for an area inside a human body. The stimulation device can be introduced into a human body, in particular into a vagina or a rectum, and has a pressure field generating device in order to stimulate an area to be stimulated inside the human body by means of a pneumatic alternating pressure field.

Insertable stimulation devices are known which can be at least partially inserted into the interior of a human body for stimulation. In particular, such devices are known which can be inserted into a natural body opening, such as a vagina or a rectum, and are dimensioned and shaped according to the respective anatomy. In particular, the stimulation of different areas inside the female or male body can lead to sexual arousal and even sexual climax. Various devices are therefore known for reaching the desired areas and stimulating them by manual movement of the device or, for example, by electrically generated tactile stimulation, such as vibration.

Possible erogenous zones of the female body include areas inside the vagina, which are colloquially referred to as the G-spot or G-zone (zone on the front vaginal wall), A-zone (zone in the abdominal area of the notch of the cervix) or O-zone (zone in the back area of the notch of the cervix towards the rectum). Vaginal erogenous zones are riddled with numerous nerve endings and can be stimulated for sexual arousal, although sensitivity can vary greatly from woman to woman. The pelvic floor muscles and the cervix, as well as the internal clitoris, are also among the erogenous zones of the female body that can be stimulated via the inside of the vagina.

In addition to the penis, one of the strongest erogenous zones in the male body is the prostate. The prostate can be reached through the rectum and can be felt and stimulated via the intestinal wall. By invasively stimulating the prostate via the rectum, a sexual climax can be achieved that differs in type and intensity from the phallically stimulated sexual climax.

EN 10 2005 042 092 A1 discloses a vibrator for insertion into a vagina. The vibrator has a type of air pump that creates changes in air pressure in the vagina when in use To do this, the volume of a chamber in the housing is changed so that slight negative and positive pressures are generated in the vagina via a housing opening at the front end of the vibrator in order to move the vibrator to simulate real movement in the vagina.

EP 3 305 266 A2 discloses a stimulation device which is not intended for insertion into the vagina, but rather for placement over the clitoris. The pin-shaped stimulation device has a pressure field generating device for generating an alternating pressure field in a pressure chamber. The pressure chamber opens into a front opening through which the alternating pressure field can be applied to the clitoris.

A stimulation device designed as a "wearable" is in US 2016/0175186 A1 disclosed. While a pump is provided in one part, which can be worn on the wrist, for example, another part connected to it can be put over the finger and thus inserted into a vagina, for example. This has a knob-like surface and holes through which a suction effect can be transferred to the wall of the vagina.

Out of US 2010/0056963 A1 a device for influencing menstruation is known. By generating pressure oscillations, which are transmitted into the vagina after the device is inserted, the flow of secretions is intended to be increased and the duration of menstruation is thereby shortened.

The object of the present invention is to create an insertable stimulation device which offers an improved type of stimulation of an area to be stimulated inside a human body.

The task is solved by a stimulation device with the features of independent claim 1. Further developments and advantageous refinements are specified in the dependent claims.

According to the invention, a stimulation device is created for stimulating an area inside a human body. The stimulation device comprises at least a first part, which is designed to be at least partially introduced into a human body. The stimulation device further comprises a pressure field generating device, which is designed to generate a pneumatic alternating pressure field. At least one pressure chamber is also provided, which is coupled to the pressure field generating device and is designed to receive an alternating pressure field generated by the pressure field generating device. The pressure chamber is arranged in the first part of the stimulation device and has at least one opening, which is also formed in the first part. The first part, the pressure chamber and the opening are designed so that an alternating pressure field in the pressure chamber can be applied via the opening to an area inside the human body to be stimulated.

The stimulation device can thus be referred to as an insertable stimulation device and the first part as an insertable part or “insertion part”, the first part being designed to be inserted in particular into a natural body opening, such as a vagina or a rectum. In particular, the shape and size of the first part are chosen to enable or facilitate insertion and, conversely, not to make it more difficult or at least not to prevent it, for example by avoiding large projections, corners or even sharp edges. In other words, the stimulation device, in particular the insertion part, is designed and dimensioned in such a way that it can be inserted into the vagina or rectum without risk of injury and used to reach and stimulate the corresponding erogenous zones. In particular, an at least partial insertion in the sense of the present disclosure therefore includes a sufficiently deep insertion to reach a desired area, i.e. placing the opening over the desired area so that it is at least partially covered by the opening and can receive the alternating pressure field.

The stimulating excitation takes place using the alternating pressure field by contactlessly transmitting a stimulation force. In particular, parts of the pressure field generating device, for example a flexible wall or membrane of the pressure field generating device, also come which is deflected accordingly to generate the alternating pressure field, does not come into contact with the body, especially in no phase of operation. This is particularly beneficial for stimulating the sensitive mucous membranes inside the body. A special stimulation effect can thus be created that differs from the effect of conventional tactile stimulation devices, for example vibrators.

Since stimulation is achieved by a pressure field applied directly to the erogenous zone through a constant alternation of positive and negative pressures, the device is designed in such a way that the dimensions of the pressure chamber to be positioned at the desired erogenous zone, including the opening, are adapted to the vaginal or anal anatomy so that a sufficient volume of air can be created in the pressure chamber for targeted stimulation. In this context, sufficient means that the volume of air is not limited by the vaginal wall or the wall of the rectum, which can be drawn into the pressure chamber, particularly in the negative pressure phases of the alternating pressure field, in such a way that the build-up of the pressure field is completely prevented or its geometric dimensions are restricted, making it inefficient for sexual stimulation.

The first part can be elongated, straight or possibly curved along an insertion direction. It can extend from a first, front end of the stimulation device in the insertion direction to an opposite second end, which can also be positioned inside the body or can also remain outside the body. Depending on the application (vaginal/anal) and the desired area to be stimulated, the first part can be designed accordingly and have a suitable cross-section, and the pressure space and the opening can be positioned and dimensioned accordingly, for example in a side wall of the insertion part, to a desired Area, for example an anterior (abdominal) wall of a vagina or an intestinal wall of the rectum adjacent to the prostate.

While the pressure chamber can be sufficiently sealed from the environment after insertion due to the contact of the mucous membranes around the first part ("self-sealing effect"), the stimulation device can comprise a sealing device which is formed and set up on the first part To seal the pressure chamber from the environment. In particular, the sealing device can be formed all around the opening of the pressure chamber, for example circular, oval or the like, depending on the shape of the opening. The sealing device can, for example have at least one projection or bead, which forms a circumferential seal to seal the pressure chamber from the environment.

The sealing device is advantageously designed in such a way that it lies against the inside of the vagina or rectum after the first part of the device has been inserted. In this way, the sealing of the pressure chamber and thus the development of an alternating pressure field can be improved. This is advantageous in order to stimulate the area to be stimulated inside the body, i.e. in particular the area which is located in the area of the opening of the pressure chamber immediately adjacent to the pressure chamber, by means of the alternating pressure field.

In the context of the present disclosure, the term alternating pressure field is generally understood to mean such a varying pressure field which has both negative pressures and positive pressures with respect to the ambient pressure, for example alternating negative pressure phases and positive pressure phases or in another predetermined pattern of possibly the same or different negative and positive pressures. This pressure alternating field prevails in the pressure chamber, especially in the area of the opening of the pressure chamber, i.e. parameters such as frequency and amplitude of the pressure alternating field must be measured at the opening. The term pressure field or pressure alternating field therefore refers to such a pressure alternating field.

In the inserted state, the pressure chamber is therefore sealed or approximately sealed from the environment, in particular with regard to both negative pressure and positive pressure, relative to an ambient pressure of the environment. In other words, flows, in particular air flows, are prevented or at least approximately prevented in both directions, i.e. from the pressure chamber into the environment and from the environment into the pressure chamber. The environment particularly includes areas outside the pressure room.

The pressure can change at a frequency of 1 Hz to 150 Hz, preferably 1 Hz to 125 Hz, more preferably 1 Hz to 100 Hz, for example 60 Hz. The pressure difference can be 20 mbar to 600 mbar, preferably 20 mbar to 400 mbar, more preferably 20 mbar to 300 mbar, for example 200 mbar, whereby the pressure difference exists between the highest overpressure and the lowest underpressure and is preferably formed symmetrically around an ambient pressure. At a normal ambient pressure of about 1 bar, the pressure change field can, for example, lead to a pressure of 0.7 bar to 1.3 bar in the pressure chamber, which corresponds to a pressure difference of 600 mbar. The stimulation device can comprise a control device, such as a microcontroller, in which the modulation of the pressure field, in particular the frequencies or frequency ranges and/or certain patterns of the pressure field can be pre-stored. Furthermore, at least one control element can be provided which can be actuated by a user in order to select and/or change a modulation of the pressure field.

The alternating pressure field is in particular a pneumatic alternating pressure field, i.e. the pressure medium is in particular air. However, it is conceivable that the alternating pressure field is transmitted via another medium, for example via a fluid such as water, gel or even body fluid, which enters or is introduced into the pressure chamber. The above-mentioned parameters of the alternating pressure field are preferably suitable and preferred for a pleasant and targeted stimulation for the corresponding erogenous zone, i.e. leading to a sexual climax. While lower values are not sufficient for sexual stimulation, higher values can be perceived as unpleasant or even pose a risk of injury to the sensitive mucous membranes.

The opening advantageously has a diameter of greater than or equal to 5 mm, preferably greater than or equal to 7 mm. The diameter of the opening is preferably less than or equal to 40 mm, more preferably less than or equal to 30 mm. Diameter can also be understood to mean other cross-sectional dimensions of non-circular openings. In particular, the values mentioned apply both to a circular opening and, for example, to an oval or elliptical opening. Corresponding values are then assumed for the major semi-axis of the ellipse. The same applies to openings of any other shape, for example other round or square shapes, whereby the size of an opening is generally preferably chosen in such a way that the area of the opening corresponds to the area of a circular opening in the range of the dimensions mentioned above.

The pressure chamber advantageously has a minimum depth of greater than or equal to 3 mm, preferably greater than or equal to 5 mm, more preferably greater than or equal to 7 mm. The minimum depth is understood to mean the length of the average flow thread from the opening of the pressure chamber (or a virtual plane defined by the opening of the pressure chamber) in the direction of and up to the pressure field generating device. Since this distance is not necessarily constant, for example due to a movable wall, the minimum depth is understood to mean the length of the flow thread from the opening of the pressure chamber in the direction of the pressure field generating device in a position of the movable wall with a minimum volume of the pressure chamber.

The mentioned dimensions of the pressure chamber and its opening are advantageous so that a pressure field required for stimulation can be built up to a sufficient extent after insertion of the device. In particular, a sufficient volume of air can be formed inside the vagina or the rectum in the erogenous zone at which the stimulation is aimed, which is not limited too much by the vaginal wall or the wall of the rectum.

The opening of the pressure chamber can have the same cross-section as the pressure chamber, so that the alternating pressure field can be applied to the area to be stimulated over as large an area as possible. In order to further increase the area on which the alternating pressure field acts, in particular the area of the opening of the pressure chamber, the pressure chamber can expand towards the opening. Alternatively, however, the pressure chamber can have a constant cross-section and be cylindrical, for example.

Conversely, it can be provided that the cross section of the pressure chamber decreases towards the opening. For example, independently of this, a cross section of a channel leading to the pressure chamber can also be larger than a cross section of the pressure chamber and/or the opening. In this way, the pressure in the area of the opening can be increased. Regardless of the geometry of the pressure chamber, the opening can also have a smaller cross-sectional area than the area of the pressure chamber adjacent to the opening.

The pressure field generating device can have a movable element for generating the pressure field, such as a movable wall or membrane, and a drive unit for causing the movable element to move. By moving the movable element, an alternating pressure field with the properties described above can be built up, particularly in a closed flow system, which is suitable for sexually stimulating an area inside a human body.

In one exemplary embodiment, the drive unit and the movable element can each be arranged at least partially or completely in the first part, that is to say in that part of the device which is set up for insertion. For example, the movable element can be a movable wall which directly delimits the pressure space, so that volume changes in the pressure space directly cause a pressure alternating field to be generated.

In addition to the first, insertable part, the stimulation device can comprise a second part which is designed to be arranged at least partially outside the human body when the first part is at least partially inserted into the human body. This can be, for example, a handle part, an operating part or another part with or without additional functionality. In particular, in contrast to the first part, the second part can be dimensioned and shaped in such a way that it can preferably not be inserted into a human body or at least only partially. Furthermore, as an alternative or in addition to operating elements arranged in the second part, a remote control connected to the stimulation device by cable or wirelessly can be provided in order to control the generation of the alternating pressure field.

In one embodiment, the drive unit and the movable element can each be arranged at least partially in the second part, wherein the pressure field generating device and the pressure chamber can be fluidically coupled to a cavity via a connecting part. The connecting part can, for example, comprise a hose, a pipe, a channel or another suitable structure which has a corresponding cavity or a fluid-carrying lumen for transmitting the alternating pressure field from the pressure generating device to the pressure chamber. Such spatial separation of the individual components allows the greatest possible flexibility in the design of the stimulation device and the structure of the pressure field generating device. In this way, depending on the arrangement of the components in the first or second part, a compact structure of the first and/or second part can be achieved. For example, the drive can be placed in the part of the stimulation device which remains outside the body, so that the insertable first part can be designed as compact as possible.

To couple the pressure chamber and the pressure field generating device, a coupling device can be provided which is designed to transmit the alternating pneumatic pressure field and to prevent a flow of fluid, in particular a flow of fluid from the opening of the pressure chamber to the pressure field generating device. This can prevent fluids such as body fluids, particles or other contaminants from passing from the opening of the pressure chamber via the pressure chamber and possibly via a connecting part into the pressure field generating device, in particular the drive unit, which could be caused in particular by capillary forces and would be difficult or impossible to clean. The coupling device thus serves as a backflow stop.

At the same time, the coupling device is set up to allow the alternating pressure field to be transmitted from the pressure generating device to the pressure chamber in the opposite direction. For this purpose, the coupling device can have a flexible and fluid-impermeable membrane. In particular, the membrane can be impermeable to fluids of any viscosity. Alternatively or additionally, however, a semi-permeable membrane and/or another filter device can also be provided, which at least retains solids.

The membrane can form a separation between two chambers in the coupling device, one of the chambers being located on the side of the membrane facing the pressure field generating device and the other of the chambers being located on the side of the membrane facing the pressure chamber. The chambers allow the flexible membrane to be deflected in order to transmit the alternating pressure field.

In addition to the pressure chamber in the first part of the stimulation device for stimulating an internal area of the human body, the device can have at least one further device in the second part for stimulating an area on the outside of the human body. In particular, if the first part is inserted into the body to stimulate a desired area inside, an increase in sexual arousal can be achieved by simultaneous stimulation of an external area. Alternatively or additionally, a further device can be provided for stimulating a further area inside the body.

For example, the stimulation device can have at least a second pressure chamber, which can have all or at least some of the features of the pressure chamber described above. In other words, just like the first pressure chamber, this can be set up to receive a pneumatic alternating pressure field from the pressure field generating device or, if appropriate, another pressure field generating device. The second pressure chamber is preferably arranged in the second part with an opening that is also formed in the second part, so that an alternating pressure field can be applied via this opening to an area to be stimulated on the outside of the human body, while the first part is at least partially introduced into the human body and preferably the first pressure chamber is placed with its opening above an area to be stimulated inside the body.

The first and second pressure chambers are preferably arranged relative to one another in such a way that simultaneous stimulation of an area inside and an area on the outside of the body can be stimulated. For example, the second pressure chamber can be designed to stimulate the clitoris or the perineum, i.e. the region between the anus and the external genitals (also referred to as the perineum), as described in more detail below for various embodiments. As mentioned, simultaneous stimulation or, alternatively, separate stimulation of the respective areas inside the body and on the outside of the body can take place using the first and second pressure chambers.

Alternatively or in addition to the second pressure chamber, the stimulation device can comprise a device for tactile stimulation, such as a vibration unit, which is designed to generate a tactilely perceptible stimulus, such as a vibration of at least a part of the stimulation device. This unit is preferably arranged in the second part, i.e. in the outer part of the stimulation device. For example, a vibration of at least a part of the second part can be generated in this way.

The first and second parts can be connected to one another in such a way that a relative position of the first and second parts to one another is adjustable. For example, the first and second parts can be movable relative to one another, so that an angle between the first part and the second part is adjustable. In particular, the first part and the second part can be connected to one another via an intermediate part, which offers a corresponding function for adjusting the relative position of the first and second parts. For example, the intermediate part can be flexible or have one or more joints or hinges. Depending on the variant for vaginal or anal use, the device can be adjusted by a user and the different areas to be stimulated can thereby be better reached.

Various variants of the stimulation device can be provided, in particular for use on the female or male body. According to one embodiment, the first part can be designed to be inserted vaginally, i.e. at least partially into a vagina, in order to stimulate an area inside a vagina. According to another embodiment, the first part can be designed to be inserted anally, i.e. at least partially into a rectum, in order to stimulate an area inside the rectum. Depending on the application, the device can be suitably dimensioned and shaped, with the opening in particular being positioned in such a way and is dimensioned such that the alternating pressure field can be applied via the opening to a region of an inner wall of the vagina, preferably to a region of an abdominal inner wall of the vagina, or to a region of an intestinal wall. The opening of the pressure chamber is preferably arranged in a side wall of the first part, preferably in an end region of the first part, whereby the position can differ depending on the type of device.

In particular in the variant for insertion into a vagina, the first part and the second part can be designed essentially coaxially, so that overall an elongated, phallic shape can result. However, for ergonomic reasons during use, it may also be desirable to bend the first and second parts relative to one another, for example at an obtuse angle, or possibly to curve the entire device or at least part of it.

Alternatively, the first part and the second part can be connected to one another via an optionally curved intermediate part, so that the first part and the second part run at least partially next to one another to form an overall C, V or U shape. The opening of the pressure chamber in the first part advantageously points towards the second part, so that it can be positioned on a front wall inside the vagina, while the second part is positioned on the outside of the abdomen in the area of the clitoris. Such a form of stimulation device enables various applications. For example, a clamping effect can be achieved so that the device can, if necessary, be used without the use of hands after the first part has been inserted. Regardless of this, the first part can be compact, in particular relatively flat, in order to allow simultaneous sexual intercourse with a male partner. The device can also remain in the inserted position independently due to a clamping effect or can also be held by the hand or by the partner.

In the variant for insertion into a rectum, in particular a male body, the opening can be positioned and dimensioned such that the alternating pressure field can be applied via the opening to an area of an intestinal wall of the rectum or rectum, which is arranged adjacent to the prostate, so that the Alternating pressure field can be applied at least partially to the prostate via the intestinal wall. While an elongated to slightly angled or curved shape is also conceivable in this variant of the stimulation device, the first part can extend essentially perpendicularly from the second part in order to form a T-shape. The second part prevents it from getting too deep Inserting the device into the rectum, whereby the device can be held in position by the user sitting down. The first part can have a curvature in order to be able to position the opening of the pressure chamber close to the prostate.

In Fig. 1 a first exemplary embodiment of a stimulation device 11 is shown, which is set up for sexual stimulation of an area inside a vagina for at least partial insertion into a vagina. The device 11 has a first part 11a for insertion and a second part 11b, which remains outside the body and is used, for example, to hold and operate the device 11. In order to achieve the functionality of the device 11 explained below, the first part 11a must be inserted into the vagina at least to such an extent that the opening 3 is placed completely inside the vagina in order to seal the pressure chamber 2 and thus create a corresponding one To ensure pressure alternating field. In the Fig. 1 The insertable device 11 shown is designed to stimulate erogenous zones on the anterior vaginal wall V.

In Fig.2 is a variant of the device from Fig.1 shown schematically in section. The first part 11a extends from a front end 51a in the direction of insertion, with the opening 3 being arranged in a side wall 51 of the housing 4. The second part 11b extends from a rear end 51b. As in all the embodiments described below, the stimulation takes place by means of an alternating pressure field of negative pressures and positive pressures, which is generated by a pressure field generating device 1 and applied directly to the desired area via the pressure chamber 2 and the opening 3.

The pressure field generating device 1 is coupled to a cavity, referred to below as pressure chamber 2, which has an outward-facing opening 3 which is designed such that a pressure field in the pressure chamber 2 can be specifically applied to an erogenous zone on the anterior vaginal wall V. By inserting the stimulation device 11, in particular the front part 11a, into the vagina, a largely closed flow system is formed by the vaginal walls V nestling against the opening 3 of the pressure field generating device 1. In the flow system, media flows are generated which are alternately directed towards the erogenous zone on the anterior vaginal wall V and away from the erogenous zone on the anterior vaginal wall V. In this closed flow system, the removal of body fluid from the pressure field generating device 1 is largely avoided.

The pressure field generating device 1 has a movable or flexible wall 5, which is deflected to generate the alternating pressure field. For this purpose, a corresponding drive unit 6 is provided, which is described in more detail below with reference to Fig. 31 to 33 is described. At least the wall 5 of the pressure field generating device consists of an elastic material, for example silicone or rubber, with the flexible wall 5 being deflected by means of the drive 6 in order to bring about a positive and negative volume change dV in the pressure chamber to generate the pressure field.

Sealing the pressure chamber 2 by the adjacent vaginal walls V promotes the development of an alternating pressure field. Although a seal due to the adjacent vaginal walls V would already be achieved with an opening 3 lying flush in the housing 4, for example, a sealing device 30 is advantageously provided, which runs in a bead-like manner around the opening 3 of the pressure chamber 2. In this way the depth of the Pressure chamber 2 can be enlarged without enlarging the entire housing 4. It has been shown that due to the clinging mucous membranes, a minimum size of the opening 3 and the pressure chamber 2 is advantageous in order to ensure a sufficient air volume to build up the pressure alternating field, especially when the adjacent vaginal wall V is drawn into the pressure chamber 2, particularly in the negative pressure phases .

To generate the pressure field, the opening 3 is preferably circular or elliptical, although other shapes are also conceivable. The opening 3 should also be large enough to cover the area to be stimulated. For example, the diameter should not be smaller than 5 mm, and preferably not smaller than 7 mm. Conversely, the opening 3 should not be too large so that the vaginal wall V is not pulled too far into the pressure chamber 2 and possibly impairs the build-up of the pressure field. The diameter should therefore not be larger than 40 mm, preferably not larger than 30 mm, and more preferably not larger than 20 mm. If the opening 3 is elliptical or oval, the major semi-axis of the ellipse should not be smaller than 5 mm, and preferably not smaller than 7 mm. The major semi-axis of the ellipse should also not be larger than 40 mm, preferably not larger than 30 mm, and more preferably not larger than 20 mm.

The depth of the pressure chamber 2, i.e. the distance between the opening 3 and the flexible wall 5 at the top dead center or at the minimum volume of the pressure chamber 2, should not be less than 3 mm, preferably not less than 5 mm, more preferably not less than 7 mm.

An alternating frequency between 1 Hz and 150 Hz, preferably between 1 Hz and 125 Hz, and more preferably between 1 Hz and 100 Hz, has been found to be suitable for sexual stimulation of the erogenous zones on the front vaginal wall, ideally up to orgasm. Higher frequencies are perceived by users as an unpleasant pulling sensation.

The pressure differences should be 20 mbar to 600 mbar, preferably 20 mbar to 400 mbar, more preferably 20 mbar to 300 mbar around the ambient pressure, the pressure difference being between the highest overpressure and the lowest underpressure and preferably symmetrically around an ambient pressure ( usually approximately 1 bar). Pressure differences lower than those specified are unsuitable for the stimulation of erogenous zones on the anterior vaginal wall V. Greater than The specified pressure differences can lead to injuries and bleeding inside the vagina and should therefore be avoided.

In addition to the pressure field generating device 1, the stimulation device 11 includes a control device 9 in order to control the drive unit 6, and in which the modulation of the pressure field is preferably pre-stored. In addition, at least one control element 10 is provided in the second part 11b, the respective modulation of the pressure field being changeable by means of the control element 10. Advantageously, the first part 11a has no operating elements that can be operated manually by a user. These would be covered anyway when the first part 11a of the stimulation device 11 is inserted into the vagina. Furthermore, the hygienic use of the device can be improved if no operating elements are arranged in the insertable part 11a of the device 11. In addition, the stimulation device 11 has a housing 4 suitable for insertion into the vagina, which includes the control device 9, the drive unit 6, the pressure field generating device 1 and an internal battery 12, the stimulation device 11 being designed as a portable hand-held device. The control device 9 makes it possible to set a stimulation pattern from the stimulation patterns of the control device 9 by means of a control element 10, the drive unit 6 being controlled in accordance with the set stimulation pattern.

Since the opening 3 of the pressure field generating device 1 is approximately sealed or almost sealed by the vaginal walls when the device 11 is inserted sufficiently deeply and thus an at least largely closed flow system is formed, virtually no air exchange with the environment takes place, which is why the removal of body fluid from the pressure field generating device 1 is avoided and the stimulation does not lead to drying out of the mucous membranes.

The temperature of the air volume enclosed in the closed system quickly adjusts to body temperature because the volumes are kept as small as possible. A heating device can be provided as an option. Furthermore, the stimulation device has no valves, which facilitates hygienic use.

The pressure chamber 2, possibly together with an adjoining connecting part, can have a change in cross-section in the direction of flow or can be designed unchanged. This results, for example, in the schematically shown variants of the pressure chamber 2 with an unchanged cross-section as in Fig.2 shown or with modified cross-section. For example, the pressure chamber 2 can be connected to a short connecting piece 2a with a reduced cross-section as in Fig.3 Between the pressure chamber 2 and the drive unit 6, a longer connecting part with a reduced cross-section can also be provided, either as a rigid pipe or channel 7 as in Fig.4 shown, or in the form of a flexible hose 8 as in Fig.5 shown. Otherwise, the Fig. 3 to 5 shown variants of the Fig.2 shown variant.

A change in the cross-section of the pressure chamber 2, or of the pressure chamber 2 with a connecting part 2a, 7, 8, has a corresponding effect on the flow velocity of the medium, ie a narrowing of the cross-section means a flow acceleration and a widening of the cross-section means a flow deceleration. The design with a flexible connecting part 8, as in Fig.5 shown, allows a high degree of flexibility in the arrangement of the components in the housing 4, whereby the device 11 can be designed particularly favorably for insertion into the vagina without loss of efficiency in the stimulation.

Fig.6 shows an embodiment of an insertable stimulation device 11, which essentially corresponds to the Fig. 2 to 5 Compared to the version shown in Fig.5 In the embodiment shown, a somewhat longer hose 8 is provided so that the drive unit 6 is located in the second part 11b of the device 11, which is not or substantially not inserted into the vagina. Furthermore, a coupling device 40 with a membrane 41 is provided, which couples the hose 8 to the pressure chamber 2 so that no contaminants get into the hose 8 and onto the movable wall 5 in order to facilitate cleaning. In other words, the pressure field in the hose 8 generated by the movement of the wall 5 is transferred via the membrane 41 into the pressure chamber 2. The coupling device 40 is described in more detail below with reference to Fig. 34 described.

Fig. 7 shows a further variant of the insertable device 11, which is essentially the same as in Fig. 2 to 6 similar to the variants shown. In this exemplary embodiment, the flexible wall 5 of the pressure field generating device 1 is integrated into the wall of the housing 4 of the stimulation device 11. In this way, the mechanical performance of the stimulation device 11 can be kept low, since instead of (as in Fig. 2 to 6 ) of a closed volume on the back, ie the side of the flexible wall 5 facing away from the pressure chamber 2, which requires a corresponding compression or expansion of the enclosed volume in the corresponding phases of the deflection of the wall 5, the environment is used as a volume for the back of the flexible wall 5. It is understood that the position of the flexible wall 5 should advantageously be chosen such that the wall 5 is essentially exposed during operation or at least is not restricted in its mobility by adjacent mucous membranes or otherwise by the user.

Fig. 8 shows a further variant of the insertable device 11, which is essentially the same as in Fig. 2 to 7 similar to the variants shown. While the in Fig. 8 shown arrangement of the components Fig. 2 corresponds, it is understood that all of the above with reference Fig. 2 to 7 Variants described are possible.

In this exemplary embodiment, the stimulation device 11 has a sensor device 70, which includes proximity sensors 71, 72 in order to enable automatic or semi-automatic control of the device 11. In general, the sensor device 70 can include at least one proximity sensor 71, 72, which is set up to detect proximity to a part of the human body. Proximity is understood to mean both a very short distance of a few millimeters at most to a part of the body and contact with a part of the body. The proximity sensor 71, 72 can be coupled to the control unit 9 and the control unit 9 can be set up to start generating the pneumatic alternating pressure field when a proximity to a part of the human body is detected and to stop generating the pneumatic alternating pressure field if there is no proximity to a part of the human body is detected. Corresponding electrical control signals are sent from the sensor device 70 to the control unit 9 and from the control unit 9 to the drive unit 6.

Beneficial, as in Fig. 8 shown, two (or more) proximity sensors 71, 72 can be provided. In order to detect in particular an insertion of the device 11, they are advantageously arranged at a distance from one another along the insertion direction of the first part 11a, preferably in front of or behind the opening 3 of the pressure chamber 2. The control unit 9 is then preferably set up to start generating the pneumatic alternating pressure field when all of the proximity sensors 71, 72 detect proximity to a part of the human body, and to stop generating the pneumatic pressure alternating field when at least one of the proximity sensors 71, 72 does not detect proximity to a part of the human body. In this way it is ensured that the generation of the alternating pressure field is only activated when the opening 3 is completely inside the vagina.

The proximity sensor or sensors 71, 72 can be capacitive sensors, optical sensors or acoustic sensors, which are suitable for detecting proximity to a part of a human body. The proximity sensor 71, 72 is advantageously arranged in the first part 11a of the stimulation device 11, so that it is positioned inside the human body during operation of the device 11. Preferably, all of the proximity sensors 71, 72 are arranged in this way in the first part 11a. However, it can also be provided that at least one of the sensors is arranged in the second part 11b of the stimulation device 11, which remains outside the body and detects proximity to an external part of the human body, for example even if the second part 11b is gripped by hand or is enclosed.

By controlling using proximity sensors 71, 72, the device 11 can be switched on and off automatically. This may be desirable, for example, for reasons of reducing noise and/or energy consumption. For example, the device 11 can be put into a “standby mode” when switched on by the user operating a control element 10. The generation of the alternating pressure field can then be controlled by means of the proximity sensors 71, 72, so that the device 11 is only active when it is inserted deep enough into the body. In this standby mode, the stimulation device 11 is in operation because the user has switched it on, but the drive unit 6 is de-energized, meaning that the stimulation device 11 does not generate a pressure field. In addition, the sensor device 70 is in operation in standby mode and carries out measurements or estimates at regular intervals.

Fig.9 shows a further variant of the insertable device 11. Insofar as the Fig.9 shown variant of one of the Fig. 2 to 8 shown variants, reference is made to the above description. In addition to the pressure chamber 2, a further pressure chamber 62 with an opening 63 is also provided in the insertable part 11a, which can be used, for example, for the simultaneous stimulation of another area inside the vagina. A sealing device 64 is arranged around the opening 63 in order to seal the second pressure chamber 62 from the environment. The first pressure chamber 2 and second pressure chamber 62 are independent of one another, since the movable wall 5 separates two volumes from one another, with one volume being connected to the first pressure chamber 2 in order to generate a corresponding first alternating pressure field in the first pressure chamber 2, and the other volume being connected to the second pressure chamber 62 in order to generate a corresponding second alternating pressure field in the second pressure chamber 62. This means that the construction of an alternating pressure field in the first pressure chamber 2 or second pressure chamber 62 also takes place when the respective other pressure chamber is not or not sufficiently sealed against the environment or is almost sealed. The additional stimulation by means of the second pressure chamber 62 can thus be used optionally. If the second pressure chamber 62 is not sealed or almost sealed, the back of the movable wall 5, i.e. the side of the wall 5 facing away from the pressure chamber 2, can be considered "vented", i.e. open to the environment, as in the variant according to Fig.7 , so that corresponding advantages arise with regard to a reduced power of the drive unit 6.

The preceding descriptions apply analogously to the embodiments of a vaginally insertable dual stimulation device described below ( Fig. 10 to 20 ) and an anal insertable stimulation device ( Fig. 21 to 30 ). Corresponding components, for example the pressure field generating device 1, the drive unit 6 or the control unit 9 are provided with the same reference numerals, whereby reference is made to the above description.

Fig. 10 shows an exemplary embodiment of an insertable device 21 for dual stimulation of erogenous zones on the anterior vaginal wall V by means of a pressure field generating device 1 with simultaneous clitoral stimulation.

In Fig. 11 a first variant of the device 21 is shown schematically in section. The device 21 has a first part 21a for insertion into the vagina with a front end 52a in the direction of insertion and a side wall 52 for contacting the vaginal wall V and a second part 21b with a rear end 52b which is dimensioned to contact the glans of the clitoris after insertion of the first part 21a. The first part 21a and the second part 21b are connected to one another by a curved intermediate part 21c so that the first part 21a and the second part 21b run at least partially next to one another so that the device 21 as a whole can be viewed as C-, V- or U-shaped, wherein a relative position of the first part 21a and the second part 21b can be adjusted, for example by a corresponding flexibility of the intermediate part 21c or by providing one or more joints or hinges (not shown). Therefore, the device 21 can be used without using hands if necessary due to a clamping effect after the insertion of the first part 21a. The first part 21a can be designed to be relatively flat in order to allow simultaneous sexual intercourse with a male partner.

The device 21 is inserted into the vagina with the first part 21a up to the intermediate part 21c. The clitoral stimulation is located in the part 21b which is not inserted into the vagina during use. The clitoral stimulation can be generated tactilely by means of a vibration or alternatively also by means of a pressure field acting on the glans of the clitoris, as described in more detail below. The opening 3 of the pressure chamber 2 in the first part 21a faces the second part 21b, so that the opening 3 is directed against a front inner wall V of the vagina. In all other respects, reference is made to the above description with regard to the functionality and the structure and arrangement of the individual components.

In the Fig. 12 to 20 The variants shown correspond to the variants of the Fig. 3 to 9 In particular, with regard to the arrangement of the components of the pressure field generating device 1, the Fig.2 and 11 , the Fig.3 and 12 , the Fig.4 and 13 , the Fig.5 and 14 and the Fig.6 and 15 .

Clitoral stimulation is as in Fig. 14 and 15 shown by a vibration unit 60 tactilely generated by means of a vibration by an electric motor with an imbalance. The electric motor can be that of the drive unit 6 and have two shaft ends, wherein one shaft end generates the flexible wall 5 of the pressure field generating device 1 for volume change for the pressure field for vaginal stimulation and the other shaft end generates the imbalance for generating the mechanical vibration of the outer part 21b.

Alternatively to the version in Fig. 14 and 15 Instead of one electric motor with two shaft ends, two electric motors 6 and 6a can be used, for example back-to-back, as in Fig. 16 shown.

This in Fig. 17 The embodiment shown corresponds in principle to the structure of the pressure field generating device 1 in Fig.7 shown embodiment. In order to keep the mechanical power of the dual, compact stimulation device 21 low with limited housing volume, the flexible wall 5 in this variant is integrated directly into the housing 4 of the stimulation device 21. As a result, the environment is used as the volume for the back of the flexible wall 5 by integrating the flexible wall 5 into the outer part 21b outside the vagina.

Fig. 18 shows an exemplary embodiment of a stimulation device 21 with proximity sensors 71, 72. The above description applies accordingly Fig. 8 Referenced.

Fig. 19 shows an exemplary embodiment of an insertable device 21, which is essentially the same as in Fig. 17 shown embodiment is the same. In addition, as in the variant according to Fig. 9 In addition to the pressure chamber 2 in the insertable part 21a, a further pressure chamber 62 with an opening 63 and corresponding seal 64 is provided in the second part 21b for simultaneous clitoral stimulation by means of another pressure field. In Fig. 19 the pressure field generating device 1 of the dual stimulation device 21 is used to generate two pressure fields that are applied clitorally and vaginally. By using a single pressure field generating device 1, the two pressure fields are not independent of one another in amplitude and frequency, but the device 21 can be designed to be compact. This means that due to the connected cavities, both pressure chambers 2, 62 must be sealed or approximately sealed from the environment in order to enable the development of a pressure alternating field in the pressure chambers 2, 62. As soon as one of the pressure chambers 2, 62 is not sealed or is not sufficiently sealed or is approximately sealed, no corresponding pressure alternating field can be built up in the other pressure chamber either. Alternatively, a second pressure field generating device with the corresponding components for generating an independent pressure field can be provided for the second pressure chamber 62, or as in Fig. 9 the movable wall 5 can be used to separate the two pressure chambers 2, 62.

Fig. 20 shows a further variant of an insertable device 21 for stimulating erogenous zones on the anterior vaginal wall V by means of a pressure field generating device 1. The structure otherwise corresponds to that in Fig. 12 shown embodiment. It goes without saying that a combination with any other variant of the pressure field generating device 1 is possible. A cavity 50 is provided on the back of the flexible wall 5, for example by means of a hollow element guided through the intermediate part 21c, to increase the volume. Similar to that in Fig. 17 shown variant, in which the movable wall 5 is free to the environment, the necessary mechanical power for compression and expansion of the air volume on the back, ie the side of the wall 5 facing away from the pressure chamber 2, can thereby be compared to the mechanical power for generating the pressure field without Such a volume expansion can be reduced, so that the inner part 21a can be made compact and compact and lightweight components (eg the electric motor) of the drive unit 6 can be used to generate the pressure field. In particular, such a structure of the stimulation device 21 allows the first part 21c to be designed so compactly as to enable or facilitate the use of the device 21 during simultaneous sexual intercourse with a male partner.

Fig. 21 shows an exemplary embodiment of a device 31 that can be inserted into a rectum, in particular for use by a male user to stimulate the prostate P by means of a pressure field generating device 1. Fig. 22 shows a variant of the device 31 schematically in section. The device 31 off Fig. 22 corresponds to the in. with regard to the generation of an alternating pressure field Fig. 2 shown device 11. In this respect, reference is also made to the above description.

The device 31 has a first part 31a with a front end 53a in the insertion direction for insertion into the rectum and for stimulating the prostate P through the adjacent intestinal wall and a second part 31b which can be positioned outside the rectum on the perineum between the rectum and scrotum and prevents the sphincter A from pulling the device 31 too far into the rectum. The first part 31a extends substantially vertically to form, for example, a T-shape, wherein a relative position of the first part 31a and the second part 31b may be adjustable, for example by providing appropriate flexibility or one or more joints or hinges ( not shown). If necessary, an intermediate part 31c, which connects the first part 31a and the second part 31b, can offer a corresponding functionality. The intermediate part 31c may further have a smaller diameter than the first part 31a and the second part 31b in order to enable the device 31 to be held by the sphincter A.

To make it easier to reach the prostate P with the opening 3, which is arranged in a side wall 53 of the insertable part 31a, the insertable part 31a should be dimensioned accordingly and, if necessary, designed to be flexible. The insertable part 31a can, for example, be designed to be adjustable in terms of its length and orientation relative to the second part 31b, so that the pressure field can optimally act on the prostate P in accordance with the respective user anatomy. The length and/or orientation can be adjusted either manually or using a remote control. After insertion, the device 31 can be used without using the hands, for example by the user sitting down.

Other descriptions regarding pressure field amplitude and frequency as well as pressure chamber dimensions are analogous to the insertable device 11 for stimulating erogenous zones on the anterior vaginal wall ( Fig. 1 to 9 ). In the Fig. 22 to 28 The variants shown correspond to the variants of the Fig. 2 to 8 In particular, the arrangement of the components of the pressure field generating device 1, the Fig.2 and 22 , the Fig.3 and 23 , the Fig.4 and 24 , the Fig.5 and 25 , the Fig.6 and 26 , the Fig.7 and 27 and the Fig.8 and 28 .

According to the Fig. 14 to 16 In addition to the embodiment of the stimulation device 21 shown, the device 31 for insertion into the rectum can also be provided with a vibration unit 60 in order to provide a tactile stimulation of the perineum or the anus by means of vibration, as in Fig. 29 shown.

According to the Fig.9 and 19 In addition to the embodiments of the device 11 or 21 shown, a further stimulation by means of a further pressure field can also be provided in the device 31, as in Fig. 30 shown. For this purpose, a further pressure chamber 63 is formed in the second part 31b. In order to achieve an improved or even sufficient sealing of the pressure chamber 62 from the environment, a corresponding sealing device 64 can be provided which is pressed against the skin of the perineum. Sealing of the second pressure chamber 62 can also be achieved here in particular by the user sitting down.

Regarding Fig. 31 to 33 A drive unit 6 of the pressure field generating device 1 is described by way of example, which in each of the above-described embodiments of the Fig. 1 to 30 can be used. The mechanical power required to generate the pressure field is determined by the volume of the pressure chamber 2 of the pressure field generating device 1, the volume change dV and the frequency of this change, as long as the volume on the back of the flexible wall 5 in the housing 4 of the pressure field generating device 1 is sufficiently large. In this case, the mechanical power required to compress and expand the air volume on the back, i.e. the side of the wall 5 in the housing 4 facing away from the pressure chamber 2, is negligible to a good approximation compared to the mechanical power required to generate the pressure field in the pressure field generating device itself.

If a compact design of the housing 4 is desired, more power may be required to compress or expand this volume due to the resulting smaller volume on the back of the movable wall 5. In order to keep the mechanical power low even with a compact design of the housing and to be able to use a correspondingly compact and lightweight drive unit 6, as for example in Fig.7 , 17 or 27 shown, the flexible wall 5 directly into the Housing 4 of the stimulation device in order to use the environment as a volume for the back of the flexible wall 5. To use the environment as a volume for the back, the flexible wall part 5 must preferably be located outside the body. So that the movement of the wall 5 is not disturbed by the user, the wall 5 can be covered, for example, by an air-permeable element.

The drive unit 6 coupled to the flexible wall 5 of the pressure field generating device 1 can, for example, consist of a rotating electric motor 13 with mechanical transmission. The mechanical translation of the rotation of the electric motor 13 into a translational movement of the flexible wall 5 of the pressure field generating device 1 can take place, for example, by means of an eccentric 14, as shown schematically in Fig. 31 shown.

The control current in the form of direct current supplied to the rotating electric motor 13 varies or controls the speed of the electric motor and thus ultimately the frequency of the flexible wall 5. The flexible wall 5 can have a bead that mechanically follows the strokes of the flexible wall largely without mechanical stress. The stroke of the flexible wall 5 is determined by the defined eccentric travel. The fixed piston stroke means a fixed reduction and enlargement of the chamber volume dV and thus a corresponding fixed pressure increase or pressure reduction, i.e. an approximately fixed amplitude of the alternating overpressure and underpressure. Different amplitudes of the alternating overpressure and underpressure cannot be set with the described drive unit on the erogenous zone. In addition, the minimum frequency is limited because the friction torque of the crank drive and the rotating electric motor (i.e. bearing and brush friction of the permanent magnet excited direct current motor) must be exceeded.

Alternatively, the drive unit 6 coupled to the flexible wall 5 of the pressure field generating device 1 can consist of a linear electric motor 15, as in 32 and 33 shown. In the electromagnetic transducer shown, the flexible wall 5 is connected to a carrier 16 and is moved back and forth in the air gap 18 by means of the control current in the air gap 18 with at least one oscillating or moving coil 17 attached thereto in accordance with the coil supply.

The flexible wall 5 of the pressure field generating device 1 is attached to a carrier 16. The flexible wall 5 can have a bead that mechanically follows the strokes of the flexible wall largely without mechanical stress. A Voice coil 17 is wound, which is fed during operation by the control current from a control unit. The voice coil 17 consists of electrical conductors made of a material that is as electrically conductive as possible (preferably copper), which are insulated from each other and from the carrier 16 with an electrically insulating varnish. The magnetic field is preferably generated by at least one permanent magnet 19 as in Figs. 32 and 33 produced in ring shape.

The magnetic flux is, for example, by means of a rear pole plate 20 (preferably as in 32 and 33 in cylindrical shape) over the upper pole plate 21 (preferably as in 32 and 33 in ring shape) via the preferably annular air gap to the cylindrical pole core 22. The rear 20 and upper pole plate 21, like the pole core 22, are made of highly magnetically permeable material (preferably a soft magnetic material alloy). Alternatively, a cylindrical permanent magnet can be used instead of the pole core 22 and, accordingly, a ring pole can be used instead of the permanent magnet 19.

The carrier 16 with the voice coil 17 is structurally centered and guided in the air gap 18 by at least one holder or suspension 23 (preferably made of plastic, textile fabric or paper) in order to prevent wobbling movements of the voice coil 17. The holder or suspension 23 is attached to a frame.

To move the flexible wall 5, the voice coil 17 is fed with an alternating control current from a control unit. The voice coil 17 is moved up or down in the magnetic field of the air gap 18 by the Lorentz force, depending on the current direction or current polarity. The range of deflection of the voice coil is determined by the amplitude of the control current. The frequency of the alternating current corresponds to the frequency of the voice coil movement and thus the frequency of the piston or membrane movement. The frequency and stroke of the voice coil and thus the movement of the flexible wall 5 can thus be controlled comparatively easily by the current frequency and current amplitude independently of one another. Due to the direct transmission, an extended frequency range from less than 1 Hz to several hundred Hz is possible with this principle. The direct current from the accumulator may need to be converted into an alternating current signal.

Alternatively, the coil can be fed with any signal form (e.g. sine, triangle, square, sawtooth signal or any form of an analog signal) of one polarity, provided the linear drive is mechanically set up accordingly. In addition, the coil can also be fed with a sine pulse width modulation.

Fig. 34 shows a coupling device 40, as used, for example, in the exemplary embodiments of Fig. 6 , 15 , 16 , 26 and 27 is included. The coupling device 40 has a membrane 41, which divides a cavity of the coupling device 40 into two chambers 42, 43, so that no fluid or general contaminants can get from the chamber 43 into the chamber 42. A change in pressure, in particular due to the alternating pressure field generated by the pressure field generating device 1, causes a deflection of the membrane 41, so that the alternating pressure field is transmitted despite preventing fluid flow. In particular, a pressure alternating field in a connecting part, such as a hose 8, can be transmitted via the membrane 41 into the pressure chamber 2, while the membrane 41 at the same time prevents, for example, body fluids or impurities from the pressure chamber 2 into the connecting part 8 in the direction of the movable wall 5 reach. The coupling device 40 allows the realization of an extended and flexible connecting element, for example a hose 8, while at the same time being hygienic, ie difficult to access and therefore difficult to clean cavities in which body fluid can collect are avoided.

Since the chamber 42 borders on the one hand on the membrane 41 and on the other hand (if necessary via a connecting part 8) on the movable wall 5, the chamber (and if necessary the connecting part 8) can also be filled with a fluid, in particular a liquid, such as water, gel or the like, instead of with a gas such as air, in order to provide a hydraulic transmission instead of a pneumatic transmission of the alternating pressure field to the membrane 41. However, to avoid the provision of liquids in cavities of the stimulation device, pneumatic transmission is preferred.

It is understood that any aspects of the preferred embodiments described above can be combined with one another in a suitable manner. In particular, the preferred embodiments are merely exemplary. For example, various aspects, such as the pressure chamber, the opening or the pressure field generating device, can be combined in any manner to create a stimulation device according to the invention for stimulating an area inside the human body. In particular, features of the various stimulation devices for the female body for insertion into a vagina and for the male body for Insertion into a rectum can be combined in an appropriate manner to reach and stimulate a desired area inside the body.
