POWER CONTROL FREQUENCY OSCI LLA TOR I ELECTRDNIC CIRCUIT MYRON E. SERVICK ATTORNEYS FIGZ 1 i ULTRASONIC TREATMENT DEVICE AND METHODS FOR USING THE SAME BACKGROUND OF THE INVENTION The present invention relates to an ultrasonic therapeutic treatment system. More specifically, the present invention relates to therapeutic treatment for relieving symptoms of certain musculoskeletal conditions of humans an animals. Furthermore specifically, the present invention relates to the therapeutic treatment of open wounds. Even more specifically, the present invention relates to such treatment by means of an ultrasonic bath, whereby the entire bath is subject to ultrasonic oscillations and the power of the ultrasonic oscillations is variable to adapt to the individual patient.

In the past there has been a great need for relieving symptoms of a number of musculoskeletal disorders, such as periostitis, contusions, sprains, strains, sesamoiditis, apophysitis, bunions, callousitis, tenosynovitis, various types of arthritis such as osteo arthritis, calcaneal spurs, neuralgia, fractures and bursitis. A number of attempts have been made in the past to develop therapeutic treatments for relieving the symptoms of certain of these disorders.

One form of such a prior art treatment involves a system to apply vibrations directly or through a coupling such as grease to parts of the body. However, such a treatment has a very limited degree of application and success. A later form of treatment comprises a therapeutic bath with a transducer located within the bath. However, this form of treatment also met with limited application and success. A primary problem with this system is that the oscillations are made uneven throughout the bath, and therefore the effect of the treatment varied greatly within the bath. All of the above methods of treatment suffer from certain inherent disadvantages in addition to the above listed disadvantages. Each patient is subjected to the same treatment. However, it has been found that each patient is not susceptible to the same treatment. This is due to differences in bone structure, skin flesh density, water content, and other musculoskeletal traits of the individual.

With thesedisadvantages in mind, it is an object of the present invention to provide therapeutic treatment to relieve the symptoms of certain musculoskeletal disorders, which treatment provides vastly improved results over the above-mentioned prior art treatments.

Furthermore, it is an object of the present invention to provide such treatment having a much greater field of application that prior art treatments.

Additionally, it is an object of the present invention to provide therapeutic treatment which is adaptable to the individual needs and limitations of each patient.

It is still a further object of the present invention to provide such a therapeutic treatment to relieve the symptoms of certain disorders in both humans and in animals.

It is to be understood that the scope of the present invention includes the treatment of all musculoskeletal disorders. For instance, the present invention encompasses the treatment of bone disorders such as fractures, and also disorders which relate to and effect bones such as calcaneal spurs and apophysitis. The present invention also encompasses the treatment of all types of muscle disorders such as contusions, membrane disorders such as periostitis, skin disorders such as callousitis, tendon disorders such as tenosynovitis, and bursa disorders such as bursitis and bunions. Furthermore, the present invention encompasses the treatment of disorders relating to and/or effecting bone and muscle, cartilage, ligament or nerve such as sprains, strains, sesamoiditis, various types of arthritis such as osteo arthritis and Mortons neuralgia.

These objects are achieved in accordance with the present invention by ultrasonically vibrating a therapeutic bath by means of ultrasonic acoustical transducers attached to the outside of the bath. This enables the entire bath to be uniformly oscillated. Such oscillations provide therapeutic relief of the symptoms of certain disorders. Means are provided to vary the power of the oscillations over a wide range. This variation of power allows each treatment to be adapted to the individual musculoskeletal limitations of the patient. Therefore, the conditions of treatment for each patient may be adjusted to provide the most effective treatment. This treatment will relieve the symptoms of certain musculoskeletal conditions in humans, and also in horses, cattle, dogs, cats and other similar livestock and pets.

Similarly, in the past there has been a great need for a method of debridement whereby open wounds may be cleaned and treated simultaneously. In the past. such therapeutic treatment and cleaning has consisted of a meticulous surgical debridement, such as wiping or sponging the open wound with a medication. However, it has been difficult by the use of such treatment to remove implanted dirt and debris from the wound.

Therefore, it is a further object of the present invention to provide a vastly improved therapeutic treatment of open wounds.

Such objects are achieved in accordance with the present invention by providing a medication in the ultrasonic bath. The ultrasonic bath performs cleaning of the wound, and simultaneously applies medication to the wound. The power of the bath is variable to adapt both to the limitations of each patient, and also to the severity of the particular wound.

Additionally, the present invention provides such a cleaning and therapeutic treatment whereby an acoustically transparent container surrounds the open wound, and contains medication which is in contact with the open wound. The wound and the container are then placed within the bath. Simultaneous cleaning and medication are performed in a similar manner as previously described.

Other objects and features of the invention will be made clear by the following description, taken together with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram of a therapeutic treatment device in accordance with the present invention;

FIG. 2 is a diagram of a perferred portable therapeutic treatment unit in accordance with the present invention; and

FIG. 3 is a diagram, partly in section, of a modified embodiment of the present invention for use in the simultaneous treatment and cleaning of open wounds.

With reference now to the drawings, a device will be described which will conveniently be used to perform the treatment of the present invention. In FIG. 1 is shown a bath 1 which is susceptible to ultrasonic oscillation. Around the outer surface of the bath 1 are provided a plurality of ultrasonic transducers 2. Transducers 2 are connected in a known manner through frequency oscillator 4 to an AC source 3. When power is supplied from source 3 to ultrasonic transducers 2, the liquid within the bath 1 is uniformly oscillated at a desired power and frequency. In order to adapt the power of the oscillations to the individual patients, variable power control 5 is provided in the control circuit. Control device 5 may be any such known device, or any commercially available such device. They are connected within the circuit in a known manner. By the provision of the control element 5, the power of the oscillation of the bath may be independently controlled and adjusted.

With reference now to FIG. 2, an example ofa practical device embodying the present invention is shown. The treatment device described with reference to FIG. 1 is conveniently mounted in a portable cart generally indicated at 10. Cart includes handle 11 and wheels 12 for portable movement. Bath 1, having transducers 2 mounted on the outer surface thereof, is conveniently and conventionally mounted within cart 10. Electronic power and control circuit 6, which includes frequency oscillator 4 and variable power control 5, is also conveniently mounted on cart 10.

It is to be understood that the practical embodiments of the present invention may be other than that specifically shown in FIG. 2. For instance, the cart 10 may have a different shape than that shown. Furthermore, the device may be mounted permanently rather than in a portable unit.

Furthermore, it is to be understood that the bath 1 may be of various shapes and adapted to receive various limbs and parts of the body undergoing treatment. For instance, the bath 1 may be particularly shaped to receive a foot, or a leg, or a hand, or an arm, or an elbow. Thus, it is to be seen that the scope of the present invention includes more than the diagrammatic shape of bath 1 shown in the figures.

Furthermore, it is to be understood that the present invention may include variable control units of a known type. For instance, as mentioned above, the frequency oscillator and transducers may be any which are commercially available and known in the art, for instance of polycrystalline ceramic material such as barium titanate or zirconium titanate. One example is the Sono" type, manufactured by Linden Laboratorles.

The variable power control may be any which is known and commercially available in the art. One such example is the Powerstat (7.5 amps/l00l40V) manufactured by Superior Electric Co., of Springfield, Ill.

The operation of the above device will now be described. The part of the body which is to undergo treatment is comfortably placed within the bath. The transducers cause the liquid in the bath to oscillate, whereby acoustic energy is conveyed throughout the liquid in the bath and the part of the body within the bath. A sufficient number of transducers are used to insure that the energy is uniformly conveyed throughout the liquid in the bath and the part of the body within the bath at the desired power level.

It has generally been found that the greater the energy applied to the part of the body undergoing treatment, the more successful will be the treatment. Thus, the variable power control is then adjusted to raise the power level as high as possible. When the power reaches the level at which there appears discomfort to the patient, the power level is slightly reduced. The practical range of power depends upon the patient, and may vary a great deal up to, for instance, a level of 10 watt per square centimeter of skin within the bath. However, it has been found that the most practical range is from 0.30 to 0.70 Watt/cm of skin within the bath.

The frequency of oscillation of the acoustic energy may be set at any desired level, usually within the range of 50 to 250 kilocycles. A particularly effective setting is I00 kc, with a tolerance of: 20 kc. Thus, according to this embodiment, the oscillator would be designed for lOO kc, and within commercial tolerances would oscillate at a frequency in the range of from to I20 kc.

The time length of each treatment may practically range from 3 or 4 minutes up to 10 minutes or more. It has been found that the treatment embodying the present invention is effective very rapidly. It has also been found that usually after 10 minutes of treatment, no additional benefits accrue. The number of treatments necessary vary a great deal, and depend on the individual patient, on the particular condition being treated, and upon the severity of the symptoms of the condition. It has been found that satisfactory results may occur after only a single treatment. It has also been found that good results have required as many as eleven treatments. It is conceivable of course, that relief of symptoms may take more than eleven treatments.

The composition of the bath may include any liquid which is sensitive to the transmission of acoustical energy, and which may be beneficial to the treatment of the particular condition. Water alone may be used, or various aqueous, oil or wax solutions may be used.

The temperature of the bath is not critical, although it has been found generally that warmer temperatures are helpful. The main consideration would be the comfort of the patient.

EXAMPLE I A patient suffering from a condition medically diagnosed as periostitis tibial tuberosity at the ankle, an old injury, was treated in accordance with the present invention. The patient, prior to treatment, suffered pain upon contact with shoes, or upon digital pressure. The ankle was placed in a bath in accordance with the present invention. The power was adjusted to 0.46 Watt/cm of skin with in the bath. This was found to be the maximum acceptable comfortable limit for this patient. The frequency of the ultrasonic oscillations was between 80 and kilocycles. The treatment was continued for 10 minutes. Two treatments such as described were performed on the patient. After the second treatment, the pain was completely gone and the patient could walk and wear shoes without pain.

A further patient was treated for symptoms of a similar condition in accordance with the present invention. The results are summarized in Table l.

The present invention is furthermore applicable to the treatment of other similar disorders than those specifically mentioned. Additionally, although the above examples all involve the treatment of humans. it is to be understood that the scope of the present invention encompasses the treatment of similar disorders in horses, cattle, dogs, cats and other livestock and pets. For instance, it is to be understood that a race horse suffering from a sprained knee joint could readily be treated in accordance with the present invention. This example is not meant to be limiting, however, since it is further to be understood that virtually any animal could be treated for any of the above specific disorders or similar related disorders.

It is also to be understood that the scope of the present invention encompasses the simultaneous treatment and cleaning of open wounds. As previously discussed there are great practical difficulties in thoroughly cleaning and treating open wounds. For instance, it is difficult by mere surgical debridement such as wiping or sponging of the wound to eliminate all debris or dirt therefrom. However, by employing the concept of the present invention, an open wound no matter how severe and dirty may be cleaned and treated simultaneously. Furthermore, such treatment and cleaning may be carried out more thoroughly and quickly than by any previously known method.

For instance, in this embodiment of the invention the liquid used in the bath shown in FIGS. 1 and 2 may include a medication. As the bath is ultrasonically vibrated, the wound in cleaned and simultaneously the medication is applied. The power of the ultrasonic vibrations is adjusted as described above. However, in addition to the discomfort of the patient, other limitations of the power include the severity of the wound and the amount of debris and dirt in the wound.

Often times, however, it may not be desirable to subject the open wound to the liquid bath. This may be for hygienic reasons. Therefore, in accordance with a further embodiment of the present invention. the advantages of the present treatment may be retained while isolating the open wound from the liquid in the bath. As shown in FIG. 3, open wound 20 is surrounded by an acoustically transparent container 21. Container 21 contains medication 22 which surrounds and covers wound 20 and which is also acoustically transparent. Container 21 may be made of any convenient material, the only requirement being that it be capable of transmitting acoustic vibrations. Examples of such material are polyethylene or polypropylene from 3-I0 mils thick. The limb with the wound and the container are placed together in the bath. Treatment is then performed as described above. The ultrasonic oscillations are transmitted from the bath through container 21 and medication 22 to simultaneously clean and treat wound 20.

Although several embodiments of the invention have been described in detail, such description is intended to be illustrative only, since many details of the performance and construction of the invention may be altered or modified without departing from the spirit or scope thereof.
