Description

The present invention relates to an improved fluid mattress assembly wherein the fluid, typically water, is infused with infrasound.

State of the art

In the prior art, so-called acoustic couches or wellness loungers are known in which actuators stimulate the lying support surfaces to vibrate. Embodiments are known in which the vibrations are introduced via stable wood panel constructions, for example in upholstered foam mattresses or waterbed supports.

In such couches commercially available actuators are used which radiate in a frequency range of about 40 Hz to about 100 Hz. It can be observed that such constructions do not correspond to the physical acoustic requirements. For example, upholstery foams are not suitable to transmit sound waves in the range of about 40 Hz to 10 kHz, since such a material acts more as an insulating material and consequently can transmit only highly attenuated vibrations to the body.

In chairs with a water pad (water mattress) stable substructures are used because of the high weight of the water-filled mattresses, for example, about 200 kg to about 500 kg, but have a cutoff frequency that is above important natural resonances of body parts, so that an effective transfer a user on the mattress only weakened or not at all takes place.

In addition, all embodiments are limited to transmitting relaxation music in the audible frequency range. At a higher frequency range of over 100 Hz, headphones, wrist vibrators and ankle vibrators are used to increase the sense of vibration and to ensure that the entire audible frequency range is transmitted.

The EP 1 325 727 A2 , the WO 1997/040748 A1 , the WO 1998/015252 A1 and the WO 2016/147125 A1 reveal water mattresses with excitation in infrasound area.

Description of the invention

The invention has as its object to provide a fluid mattress assembly which is optimized for the needs of the user.

The object of the invention is achieved by a fluid mattress arrangement according to claim 1, a couch according to claim 7 and a method according to claim 10. The dependent claims claim preferred embodiments.

A fluid mattress assembly according to the invention comprises a mattress body with an outer shell, wherein a fluid is enclosed by the outer shell. The fluid mattress assembly further includes an actuator configured to excite the fluid in the mattress body with a signal in the infrasonic range. The fluid mattress assembly further includes a sensor configured to detect at least a physiological size of a user of the mattress. The fluid mattress assembly further comprises a control device, which is designed to control the actuator in dependence on the detected physiological quantity, whereby the actuator changes the excitation of the fluid in the mattress body in the infrasonic range.

According to the invention, a feedback is generated in order to optimize the signal in the infrasonic range for exciting the fluid in such a way that the user feels as comfortable as possible on the fluid mattress arrangement or if the energies important to him are introduced precisely in the body through interference formation in three-dimensional space.

In one embodiment, the fluid may be largely a liquid. The fluid can be largely water. The term is to be understood as meaning that the presence of other fluids, such as air or other media having water-like densities within the outer shell, can not be excluded.

In one embodiment, the fluid mattress assembly may include a plurality of actuators. The control device can be configured to control the actuators in such a way that, depending on the control, predetermined interference patterns result on and in the fluid mattress arrangement. By resting the human body on the mattress, its mass, which consists largely of water and has a similar density, is coupled to the vibrating system. The vibratory three-dimensional space expands around this body.

By forming localized interferences, deterministically certain locations of a user's body lying on the fluid mattress assembly can be excited. The fact that a feedback takes place by the at least one sensor results in a self-learning system with the aid of an intelligent control and an algorithm in which the excitation by the signal in the Infrasound range and / or is optimized by the local interference patterns so that they are adapted to the particular application by the respective user or optimized.

The controller may drive the actuators to deliver an infrasonic signal having a different amplitude to the fluid. As an alternative or in addition, the control device can actuate the actuators in such a way that they deliver an infrasound signal with a different frequency to the fluid. As an alternative or in addition, the control device can actuate the actuators in such a way that they deliver an infrasonic signal with a different phase to the fluid. The generation of local interference is known to the person skilled in the art and need not be specified further here.

The sensor may be a brainwave or voltage sensor configured to detect the brainwave currents or voltages of the user. Alternatively or additionally, the sensor may be a pulse sensor configured to detect the user's pulse. Alternatively or additionally, the sensor may be a blood pressure sensor configured to detect the user's blood pressure. Any other sensors can be used to detect the condition of the user. In particular, the brain waves can be measured, the individual organs or individual body parts can be assigned to improve the excitation and thus the functionality of these organs or body parts by an infrasonic signal.

At least one actuator can be arranged on the underside of the fluid mattress arrangement or of the mattress body. Alternatively or additionally, at least one actuator can be arranged on a side wall of the fluid mattress arrangement or of the mattress body. Alternatively or additionally, at least one actuator can be arranged on a side wall which is not orthogonal to the underside of the fluid mattress arrangement or of the mattress body. This three-dimensional arrangement of a plurality of actuators allows more interference patterns to be generated.

The invention also relates to a couch with the previously described fluid mattress arrangement.

The couch can have a plate which is arranged under the mattress and is arranged under the at least one actuator. The plate may be formed as a vibration plate which distributes the vibrations of the actuator in the fluid mattress assembly. Furthermore, the plate can support the mass of water, so that the actuator is not burdened by the mass of water.

The couch may further include a decoupling member disposed between the fluid mattress assembly and a frame of the couch and decoupling vibrations of the fluid mattress assembly and / or the panel from the frame. In one embodiment, the decoupling member may include a plurality of springs disposed in the vertical direction between the fluid mattress assembly and the plate and the frame of the lounger. The frame may support the fluid mattress assembly opposite the floor of a room.

The invention further relates to a method of exciting a fluid in a fluid mattress assembly, comprising the step of exciting the fluid in the fluid mattress assembly with a signal in the infrasonic range. The method further comprises the step of detecting at least one physiological size of the user of the fluid mattress assembly and the step of adjusting the excitation of the fluid in the fluid mattress assembly in response to the detected physiological size of the user of the fluid mattress assembly.

Detailed description of the figure

1 shows a perspective sectional view of a couch according to the invention 100 with a water mattress according to the invention 102 , The water mattress according to the invention 102 includes an outer shell 134 in their interior with water 106 is filled. Under the water mattress 102 is a vibration plate 118 arranged the water mattress 102 supports down. Under the water mattress 102 and under the vibration plate 118 are a plurality of first actuators 108 arranged, which is a signal 130 in the infrasonic range to the vibration plate 118 and thus to the water in the water mattress 102 submit. The side wall of the outer shell 134 the water mattress is due to an obliquely arranged side frame 124 . 125 the couch diagonally, ie not orthogonal to the underside of the water mattress 102 arranged. On the side walls of the water mattress are second actuators 110 arranged, which have a pathogen membrane 128 vibrations 130 in the infrasound area in the water inside 106 the outer shell 134 the water mattress 102 transfer. The pathogen membrane of the Aktors is with compression springs 126 supported against the hydrostatic water pressure.

A frame 112 supports vibration damper 114 , in turn, the vibration plate 118 support. Through the vibration damper 114 , which are formed in the embodiment shown as coil springs, no mechanical vibrations or only to a very small extent by the vibration plate 118 over the vibration damper 114 on the distance surfaces 116 of the frame 112 transfer. This mechanically decouples the vibration plate so that its modes are not affected by the modes of the frame 112 depend.

The couch also has a plurality of sensors 136 For example, sensors for measuring brainwaves or voltages applied to a controller 138 is coupled. The control device 138 controls the majority of first actuators 108 and the plurality of second actors 110 so that in the water predetermined wave pattern 130 form. The wave patterns may vary depending on the sensors 136 detected currents or voltages are used for optimizing that the excitation 132 in the infrasound area on the body of a user 104 standing on the water mattress 102 is optimized for a predetermined treatment purpose. A water mattress 102 is preferred because it has the same density as the human body and hence the signals in the infrasonic range 130 . 132 especially good of the water mattress on the user 104 can be transmitted.

The control device 138 controls the first actuators 108 and the second actors 110 so on that targeted interference 130 . 132 So vibration maxima with high energy and vibration minima with low or no energy in the water inside 106 the water mattress as well as in the body of a user 104 arise. The vibration patterns can stimulate individual body parts or organs of the user 104 create and thus stimulate a cure. The individual frequencies and frequency mixtures can be adjusted so that the desired organ is stimulated.

A first type of actuator may have a frequency range of about 4 Hz to about 40 Hz, for example, for the excitation by means of the vibration floor 118 using high-energy infrasonic waves. These actuators can work with a drive power of up to about 2 kW and a vibration mass of several kg. The lateral actuators 110 may have a frequency range of about 0 Hz to about 20 Hz. Furthermore, spa music with bass pulses in a range of about 40 Hz to about 100 Hz may be introduced to increase the stimulation of relaxation. All actuators are either on the vibration floor 116 or on the side walls 124 appropriate. The user 136 can also hear relaxation music through a headphone in the range of 40 Hz to about 20 kHz.

Since the human body has about the same density as water, the three-dimensional forms of vibration plant 130 passing through the actuators 108 . 110 be generated in the body of the user 104 continued. In this way, even lower-lying organs inside the body of the user 104 be reached by the waves. The application of the invention is based on triggering a reaction in the form of sensations in the brain with the introduction of energy, optionally in the resonance region of individual organs or body parts. These currents and voltages are through the sensor 136 measurable. For this purpose, it is assumed that it can be assigned which brain currents can be arranged to which organ or body part and which brain currents or which patterns of brain currents indicate a positive contribution to the health of the human body through the infrasound region.

For example, neuronal scientific intelligence can be used to measure brain waves that are related to the vibration patterns introduced 130 . 132 react. The brain waves in response to the vibrations 130 . 132 in the form of voltages and / or currents are in turn provided by intelligent software of the control device 138 in suggestions for the actors 108 . 110 converted, so that a closed-loop regulation arises. Iteratively, therefore, in comparatively short cycles, the relevant areas (hot spots) in the body of a user 104 be detected where energy at certain frequencies has a positive effect. Consequently, the present invention couch has 100 the goal of a balanced energy balance in the body of a user 104 to create. For every user 104 an individual oscillation pattern can be generated, which can be stored on a data medium. Furthermore, the combination of excitation and sensor signal can be used for diagnosis of diseases.

By means of the previously described headphones and the sensor 136 Tinnitus can be analyzed and Tinnitusfrequenzen be measured, which are mixed via an active acoustic elimination (Anti Noise) or a complementary signal directly into the music signal. The brain responds to this stimulation in such a way that the self-production of the whistle signal or noise signal is adjusted in the case of recurring treatment.

The couch 100 poses with the actuators 108 . 110 with an effective frequency range of about 0 Hz to about 20 kHz (infrasonic range and audible range) is a platform with the free activation of the actuators 108 . 110 arbitrary vibrational phenomain 132 in the body of a user 104 can be formed.

The invention has the advantage that on the one hand infrasound can be introduced three-dimensionally into the body of a user and on the other hand immediately feedback on the physical well-being of the user is generated, so that the excitation by infrasound can be adapted to the respective user immediately.
