Abstract
Description
- This invention refers to an innovative localized hydromassaging device.
- There are known localized hydromassaging devices composed of a head which dispenses jets of water, sometimes mixed with air, which can he brought close to or into contact with parts of the body so that the jets produce a beneficial hydromassaging effect on the skin.
- The general scope of this invention is to provide an innovative localized hydromassaging device which combines the massaging action produced by a stream of water with a micromassaging action produced by generation of ultrasonic waves.
- This scope is achieved, according to the invention, by providing a localized hydromassaging device for the body comprising a head which dispenses a stream of water in correspondence with one of its faces designed to be disposed facing the body, the head containing transducer elements which introduce ultrasonic waves into said stream of water.
- The innovatory principles of this invention and its advantages compared to the known technique will be more clearly evident from the following description of possible exemplificative embodiments applying such principles, with reference to the accompanying drawings, in which:
- figure 1 shows a schematic cross-sectional view of a first hydromassaging device made according to the invention;
- figure 2 shows a schematic cross-sectional view of a second hydromassaging device made according to the invention;
- figure 3 shows a schematic enlarged cross-sectional view of a possible alternative embodiment of a detail of the hydromassaging device;
- figure 4 shows a schematic cross-sectional view of a further possible alternative embodiment of a detail of the hydromassaging device;
- Innovatively, disposed in contact with the stream of water is an ultrasonic wave
emitting transducer element 15 controlled by anelectronic circuit 18. The term "in contact" is used here to refer to an acoustic contact, that is to say, transmission of ultrasounds with minimum attenuation. For example, thetransducer 15 can be a known piezoelectric transducer. Thecontrol circuit 18 can be a known generator of electric signals of suitable frequency, which is well known to the expert in the field and consequently not further described or shown since it is easily imaginable especially in the light of the following operative description. - The transducer element consequently produces ultrasonic waves which spread through the stream of water dispensed by the device.
- To improve the transmission between transducer and water it can also be envisaged to connect the transducer to the
plate 14, made for example in the form of a thin metal element, so as to produce ultrasonic vibration of theentire plate 14. - By directing the jets of water against a part of his body, the user consequently receives a massage produced by the normal stream of water as well as a massage produced by the component of ultrasonic waves conveyed by the water itself.
- This offers a beneficial massaging action both at epidermal level and at a deeper level, depending upon penetration of the ultrasounds through the tissues.
- Since water is the means of transmission of the ultrasounds, it may be advantageous to provide a baffle or
peripheral edge 16 which forms a substantially closed chamber between thewater dispensing surface 14 and thesurface 17 of the body. Thebaffle 16 can be made either in rigid material, for example moulded in one piece with thecasing 11, or with at least its free edge in pliable material, for example rubber. The baffle made of pliable material is advantageous in that it is more comfortable to use and adapts more readily to the surface of the body. - During use, the space defined by the
edge 16 fills at least partially with water thereby facilitating the transmission of ultrasounds between theemitter 15 and the surface to be treated 17. Thebaffle 16 can also be useful to prevent excessive splashes of water in the surrounding area. - In addition to being made in the form of a closed-walled cup the baffle can also be made as a plurality of pliable elements. For example, the baffle can be made in the form of bristles of a brush, so as to provide a further massaging and/or superficial frictioning action as it is passed over the body.
- Even though the transducer must transmit ultrasounds to the stream of water, its position can obviously differ from the one shown in figure 1.
- Figure 2 for example shows an alternative disposition. For the sake of convenience, elements similar to those shown in figure 1 will be indicated in figure 2 with the same numbering as in figure 1 but increased by 100. Consequently, there is a device, generically indicated by
reference 110, comprising acasing 111 which is internally supplied with a stream of water by means of aconnection 112 to a source of water under pressure. Thecasing 111 is provided withnozzles 113, which produce jets of water directed towards the outside of the casing, which are made for example in the form of holes in awall 114 of thecasing 111. A circumferential edge orbaffle 116 similar to thebaffle 16 of figure 1 can also be provided. - A
transducer element 115 emitting ultrasonic waves (controlled by a circuit, not shown, similar to thecircuit 18 of figure 1) is inserted in the chamber inside the casing through which the stream of water flows before it is ejected from the nozzles. The ultrasonic waves consequently propagate through the water which flows through said chamber before the water is ejected from the nozzles, thereby obtaining an excellent contact for transfer between the transducer and the water which is dispensed by the device. - In order to increase the massaging effect, the
device 10 according to the invention can be provided with further mechanical massaging means. For example, as shown in figure 2, idle rollers can be provided, supported on the device by means of spindles parallel to each other and to thesurface 117 to be treated, so as to run freely over thesurface 117 when the device is moved over the latter. - The rollers can have patterned surfaces in order to facilitate the massaging action. As shown by way of example in figure 2, the rollers can for example be provided with radial massaging protrusions, made of rigid or rubbery material.
- Figure 3 shows an enlarged view of an alternative embodiment of water dispensing nozzles, forming a device according to the invention. In said embodiment, the
nozzles 213 which emit jets of water comprise a first portion or inlet duct 219 for admission of water into the latter and a second portion oroutlet duct 220 for the jet of water. For example, thenozzles 213 can be obtained in the thickness of aplate 214 disposed in the device similarly to theplate 14 of figure 1. - Disposed along the duct conveying water into the nozzles are
transducer elements 215 connected to a control circuit (not shown) similar to the one indicated byreference 18 in figure 1, in such a way that each transducer transmits ultrasonic waves to the water passing through the nozzle. - The water ejected by the nozzles thus transfers the ultrasonic component towards the body of the user.
- Figure 4 shows a further embodiment of nozzles applying the principles of the invention. A
nozzle 313 is composed of aportion 321 tightly rotatable in a housing to receive a flow of water from aninlet duct 319. The direction of the jets can be easily adjusted by rotating thespherical portion 321 in its housing. - The water flows through passages 322 (for example, three disposed radially equidistant) made in the
portion 321. - Advantageously, disposed in each
passage 322 is aduct 323 connected with anair passage 324. As it flows through thepassages 322, the water under pressure sucks in air from theducts 323. The jets of water ejected by the nozzles thus contain a certain percentage of air, thereby increasing, as is known, the massaging action. - Disposed along the route of the stream of water before it is ejected by the nozzle is a transducer element 315 which emits ultrasonic waves, similar to the
elements - In this way, ultrasonic waves are transmitted to the water before it is ejected from the nozzles.
- As can be seen in figure 4, the
nozzles 313 can be through housed in awall 314 of the localized hydromassaging device. This wall can also be a wall disposed in the same way as thewall 114 of figure 2 and theduct 319 can be composed of the incoming water chamber inside the casing of the device as shown in figure 2. - At this point it will be clear that the intended scopes have been achieved by providing a localized massaging device comprising an ultrasonic massaging action.
- It has been found that the depth of penetration of the ultrasounds into the body of the user and the efficacy of the treatment depend upon the relation between the frequency of the ultrasounds emitted by the transducers and the area of the body treated. That is to say, for each area of the body there are emission frequencies more effective than others.
- It has been noted that the best results are obtained by providing the possibility of regulating the ultrasound emission between 0.2MHz and 5MHz, in particular between 0.5MHz and 3MHz. As can be easily imagined by the expert in the field, this can be easily obtained by suitably choosing the transducers, so that they can function within the desired frequency range, and by providing a generator for supplying power to the transducers which has an output frequency that can be regulated between 0.2MHz and 5 MHz, in particular between 0.5MHz and 3MHz. The regulation for example can either be continuous or achieved according to fixed steps. Fixed step regulation can be advantageous in order to simplify the use of the device. In fact, each frequency that can be selected can be indicated by its use (for example, hands, back, etc.) instead of by its actual frequency value, thereby making the apparatus easier to use.
- In order to prevent the area of the body subjected to treatment from overheating, it has been found preferable not to exceed the power of 3W/cm² as an effective value in ultrasonic emission.
- Moreover, it has been found that the emissions can be obtained with an intermittent rather than a continuous pattern, for example by alternating emission periods with non-emission periods with a ratio ranging from 1/10 to 1/2, in particular in the region of 1/5.
- For example, it is possible to obtain emission periods ranging from 0.1 to 5ms and non-emission periods ranging from 2 to 10ms. Advantageously, the emission periods can have a duration in the region of 1ms and the non-emission periods can have a duration in the region of 5ms.
- The foregoing description of embodiments applying the innovative principles of this invention is obviously given by way of example in order to illustrate such innovative principles and should not therefore be understood as a limitation to the sphere of the invention claimed herein.
- For example, if it is considered sufficient, the rollers themselves can perform the function of a baffle or container for the water. In this case, the
baffle 116 can be eliminated, at least in the vicinity of the surface of the rollers. - The elements shown in the various figures can obviously be combined with one another. For example, the
rollers 125 can be inserted in a device as shown in figure 1, just as the nozzles made as shown in figure 3 or 4 can be used in devices of the type shown in figure 1 or 2. - The device can be advantageously made in the form of a dispenser head connected by means of a flexible hose to the source of water (preferably hot), the electric cable connecting the transducers to the generator being disposed in the hose or coupled to it. For easy use, the dispenser head can be made for example in the form of a "hand shower" or the like. The device can obviously be integrated in shower cubicles or bath tubs, for use in the latter. Alternatively, it can also be integrated in devices for local treatment, such as plantar massagers or cervical massagers, etc..
