Description

[0001] The invention relates to a device for stimulating the male genitalia, consisting of a suction device (1, 8) with adjustable power, an applicator (3) and a suction hose (2) connecting both parts.

[0002] It is known that an airflow through a tubular structure can excite elements with a low spring constant within it to low-frequency vibrations. A good example of this is the snoring process, in which the soft palate exposed to an airflow is excited to low-frequency vibrations and fluttering.

[0003] Devices operating on this principle are also suitable, in principle, for stimulating the male genitalia, with low-frequency fluttering vibrations in the range of a few Hertz being perceived as particularly stimulating and pleasant. For this purpose, the penis is inserted into the applicator, which has a cylindrical cavity with an inner diameter slightly larger than the outer diameter of an erect penis. The suction device then exposes the penis to a suction airflow via the connecting tube, which can stimulate fluttering vibrations, particularly in the narrowed section of the applicator formed by the penis.

[0004] Devices for targeted genital stimulation of the male genitalia, in which a suction current is used to induce vibrations in the area of ​​an applicator surrounding the penis, are known.

[0005] Thus, DE20 2004 003 855 U1 describes a “suction-vibration converter for genital stimulation”, with a tube made of a rigid material with a suitable diameter (applicator) into which the user’s penis is inserted proximally and an external suction device (preferably a household vacuum cleaner) is connected distally.

[0006] Also known under this general term are devices with applicators in which a highly elastic hose is enclosed by a chamber with a rigid outer wall, and the cross-section of the hose as well as its elastic preload is variable via a vacuum that can be regulated in the chamber. (DE 10 2022 115 603 B3)

[0007] WO 1996007375 A1 characterizes a device consisting of an applicator with a rigid, tubular outer casing, a flexible tube arranged therein and inverted over both ends of the tube from the inside out, and a distally arranged rigid sealing cap, creating an airtight chamber in the annular space and a cylindrical cavity in the center into which the penis can be inserted. A motor-driven diaphragm, which changes volume like a bellows and is pneumatically coupled to the airtight annular space, generates pressure changes that cause the applicator to move independently back and forth in the axial direction.

[0008] WO 2019102458 A1 describes a similar device, in which the outer wall of the tube-shaped applicator has a multi-layered structure. This device features several openings in the wall of a rigid tube surrounded by an elastic, air-permeable outer skin made of nylon. At the distal end of the tube, there is a connection for a vacuum pump and an opening for controlling the vacuum with the thumb. At the proximal end of the tube, there is another opening with an elastic seal through which the penis can be inserted. Extending inwards from this opening is a tube made of elastic material, the distal end of which lies loosely inside the tube and may have multiple slits or fringes.By applying a vacuum to the distal end of the tube, the elastic outer skin is drawn inwards through the openings in the tube, which massages the penis, as do the fringes, which are stimulated to flutter in the airflow.

[0009] Among the disadvantages of the solutions mentioned are, above all, inadequate hygiene precautions. For example, replaceable ejaculate filters were not considered in the design, nor was the possibility of easily and effectively cleaning the applicator and the hose connection to the suction device. Furthermore, it is known that the energy transported by an airflow increases with the cube of the flow velocity, which means that even in a flow channel with poor resonance conditions, vibrations can be excited simply due to the increasing turbulence at higher air velocities.

[0010] Devices that, according to the general definition, operate with a suction device as their sole energy source, depend on the desired—and only the desired—fluttering vibrations arising spontaneously and being sustained. Although resonances naturally develop in every tube system that such a device embodies, which can be excited by a suction flow, a good interaction with the desired fluttering vibrations is not guaranteed per se, leading to high energy consumption, airflow, and also undesirable noise.

[0011] High air velocities can lead to significant negative pressure in the applicator area—especially if the airflow at the applicator's inlet is suddenly blocked—and may pose a health risk during use. Furthermore, high air velocities and flow rates, in addition to increased noise levels, also result in an undesirably strong cooling of the penis, which is perceived as unnatural and unpleasant.

[0012] The development goal for a device for stimulating the male genitalia should therefore be to ensure that the desired low-frequency fluttering in the applicator begins even with the lowest possible airflow. This means that the entire flow channel should have a design that maximizes the resonance conditions for the generation of flutter oscillations and vibrations in the applicator, allowing these to be excited even with minimal airflow. Such an improvement can be achieved solely through design features like those used in the invention.

[0013] The invention therefore aims to provide a highly effective device for genital stimulation, as defined in the preamble. This device generates the vibrations and fluttering perceived as stimulating in the applicator very effectively, even with low airflows, while simultaneously offering the user considerable freedom in shaping the fluttering and the associated experience. Further objectives include ensuring safe and ergonomic use, as well as maintaining the hygienic condition of the device.

[0014] The invention solves this problem by means of a device having the features of the main claim. The further problems are addressed by the features of the dependent claims.

[0015] The idea behind the device according to the invention is to achieve the best possible resonance matching of the tube system to the low frequency range of the desired flutter vibrations by forming at least parts of the tube system with elements that are themselves capable of oscillating in this frequency range. A tube system made of rigid tubes would, as is known, have a length of approximately 8.5 m for a resonance frequency of, for example, 10 Hz, corresponding to a quarter of the wavelength λ. If, however, the tube system contains elements that themselves represent energy storage devices, such as air chambers or similarly acting spring systems, the resonance frequency of a tube system only two meters long, which would otherwise be in the range of around 45 Hz, can be reduced to a few Hertz.

[0016] Additionally, an active element, such as a controllable valve, can be placed in the air path to specifically stimulate and maintain such a vibration.

[0017] In the present case, the primary energy storage devices according to the invention are the hose (2) connecting the suction device (1) and the applicator (3), as well as the applicator (3) itself.

[0018] They can be designed, in particular, as a spiral hose with at least one spiral spring embedded in a soft matrix (claim 2) or as a corrugated tube (claim 3). Alternatively, air chambers, spring-loaded bellows, or similar energy storage devices coupled to the pipe system at a suitable point are also possible.

[0019] The two hose shapes mentioned are particularly suitable for the system according to the invention, since they can be designed with the desired spring characteristic in the axial direction and be sufficiently kink-resistant but flexible in the radial direction, and can also be seamlessly integrated into the general structure according to the preamble.

[0020] The aspect of hygiene, which is part of the further scope of application, is addressed by the inventive design, firstly, by a filter (5) which (claims 4; 5) is arranged between the applicator (3) and the suction hose (2) in a housing (6, 10) and is easily replaceable or washable, and secondly, by the exceptionally simple design of the applicator (3) as a simple hose with an adjoining filter box (6) with a removable closure element (10). All elements can be designed so that they can be easily cleaned and quickly dried at any time, not only under running water but also in a standard household dishwasher.

[0021] For safe and ergonomic handling, the applicator (3) according to the invention provides, firstly, a skin-compatible inner wall made of soft plastic, such as TPU, silicone rubber, or a plastic with similar elastic properties. Secondly, it provides a proximal end ring (7) made of at least skin-compatible material, which acts as a closing element and softly encloses the structure of the corrugated tube or spiral hose (claims 6; 7) without significantly reducing the inner diameter. It is tightly bonded or at least form-fitted and tightly connected.

[0022] If an adjustable valve (18) is additionally installed in the air path, the generation and maintenance of the oscillation can also be positively controlled. A particularly advantageous, because backforce-free, design of such a valve is a rotary valve with a symmetrical flap, whereby the switching frequency can be set to twice the rotational speed. In this case, the design according to the invention enables any desired change between slow suction oscillations and higher-frequency flutter oscillations, which can also be varied over time during the application, e.g., randomized or otherwise program-controlled.

[0023] If a sensor element (19) is additionally provided in the design of a rotary valve, it can be controlled specifically so that it remains in the "open" position. In this case, the flutter oscillation can also be used in passive resonance, and it is possible to quickly switch between the two types of excitation.

[0024] The invention will now be further explained in a non-restrictive manner by describing particularly preferred variants, embodiments and considerations for the full development of a device according to the invention with reference to the drawing and the associated list of reference numerals.

[0025] A specific full configuration of the device according to the invention comprises, in addition to the power-controllable suction device 1, 8, 9, the suction hose 2, the applicator unit 3 and a preferably external 230V power supply 12 or a battery unit for location-independent operation.

[0026] Practical experience has shown that users find it disturbing when the suction device 1 generates a noise level above approximately 60 dB. It is therefore important that it is housed in a casing with very good sound insulation. Among the various non-user-specific parameters that influence the fluttering effect, a finely adjustable power control 8 for regulating the airflow is also an important element. An easily accessible and simple-to-operate on / off switch 9, as well as a safety valve 17 in the applicator, constitute an essential safety feature in handling, in case the power control fails and / or the suction motor runs away.

[0027] For example, a standard CPAP hose in the usual spiral design, 1.80 m long with a 22 mm inner diameter, is suitable as suction hose 2. Hoses of this type are not only very light and flexible, making them easy to handle, but they also have the desired low spring constant in the axial direction, especially at the specified length. This means that they effectively dampen high-frequency components from the suction device, while also acting as an energy storage medium for low frequencies, including the desired fluttering sound. The ends of the hose are also fitted with soft rubber rings 15, which have proven ideal for use with simple quick-connect couplings 14, 15, 16, as are desirable for user-friendly handling of such equipment.

[0028] As the central element of the device according to the invention, the applicator 3 forms the most important interface between the user 4 and the device. Due to the different anatomical conditions and phases of erection in the application area, it makes sense to be able to select the applicator 3 from a set with graduated sizes, e.g., inner diameters from approximately 32 to 50 mm, and to be able to change it quickly, preferably by simply moving the suction tube 2 to a different applicator 3 from the set during operation. Since the application can generally be carried out without lubricant, the user will choose a size in which the penis 4 is both still freely movable and not lost.

[0029] In a preferred embodiment as a spiral hose with a spiral made of a hard material and a soft matrix, according to claim 2 or as a corrugated tube according to claim 3 - each made of skin-compatible plastic - the applicator 3 has good vibration capability in the low-frequency range, but also flexibility that allows the user 4 a great deal of design freedom during application.

[0030] In a further particularly preferred embodiment, the applicator 3 according to claim 8 can already be pre-bent in a banana shape, which has proven advantageous in many cases in practice.

[0031] To optimally meet hygiene requirements, the spiral hose or corrugated tube of the applicator 3 terminates in a filter housing 6 with a quick-release fastener 10 (e.g., bayonet fitting). A replaceable, preferably washable, filter 5 is placed inside this housing to separate the air spaces and reliably separate any aspirated ejaculate. Suitable filters include, for example, standard industrial-grade HEPA filters, such as those commercially available for cordless handheld vacuum cleaners. In an improved version, the filter can also be combined with a vortex separator integrated into the filter housing, such as a cyclone separator.

[0032] The locking element 10 for the filter housing 6 can advantageously be designed as a bayonet-style lid, which on the opposite side simply has an opening for the insertion of the suction hose 2. This ensures a quick and easy replacement of the entire applicator unit during operation. Cleaning after use is also particularly easy, as the assembly according to the invention can be quickly and easily disassembled into its parts and cleaned, for example, under running water, and in the case of the applicator 3, also in a dishwasher.

[0033] In a further particularly preferred embodiment of the invention according to subclaim 10, a controllable valve 18 is arranged in the air path. If the valve is designed as a rotary valve with a symmetrical lens-shaped flap according to subclaim 11, it can interrupt the airflow variably in slow or rapid succession and thus actively stimulate and control the formation of a flutter oscillation with an adjustable frequency. To enable the device to be used temporarily or alternately without the rotary valve, a controlled stopping of the flap in the "open" position is provided. The necessary position determination can be easily implemented by a sensor element 19, e.g., a Hall sensor or a photoelectric sensor. This results in an interesting, readily variable interaction with the passive resonance behavior of the air duct, which broadens the apparatus's range of applications.
