Description

TECHNICAL FIELD [0001] The present invention relates to an ultrasound therapy apparatus having a blood flow monitoring function,

 The present invention relates to a fusion therapy device combined with an ultrasonic Doppler blood flow / elasticity measurement module using a method of moving and manipulating a driving position electronically without moving an ultrasonic transducer in contact with skin. The present invention relates to an ultrasound therapy apparatus having a blood flow monitoring function capable of continuously monitoring a blood flow state and a post-treatment improvement state of a treatment region by ultrasonic therapy by combining a Doppler blood flow / elasticity module.

In recent years, the physiological effect and the therapeutic effect of low intensity ultrasound have been well known, and a low intensity ultrasound therapy apparatus has been developed. Most of the ultrasonic devices for physical therapy use ultrasonic waves while applying liquid gel to the skin of the subject and moving the ultrasonic head in contact with the skin. At this time, if the output of the ultrasonic wave is strong, it damages the cell tissue, so the safety can not be increased. Therefore, in order to apply ultrasound to a wide range, ultrasound waves are applied to a wide range as the user moves the ultrasound device by hand.

Ultrasonic apparatus using a general ultrasonic contact movement therapeutic method (stroking technique) has a problem that since a user or a physical therapist directly transfers an ultrasonic device while applying ultrasound to a wide area, it is troublesome and can not be used for a long time.

That is, the conventional ultrasonic therapeutic apparatus continuously moves the ultrasonic transducer by moving the ultrasonic transducer continuously to avoid heat accumulation due to the occurrence of excessive heat generation at the center of the ultrasonic transducer, that is, the so-called hot spot, And it is proceeding as a method of avoiding heat accumulation in human tissues by energy. However, there is a problem that the physical therapist has to keep moving the ultrasonic head manually during the treatment time, and there is a problem of fatigue caused by repeated and long working of the physical therapist, There was a problem of incidence of occupational diseases such as pain.

The ultrasonic therapeutic apparatus using the general ultrasonic contact movement therapeutic method (stroking technique) is used for treatment of damage to soft tissue cells, treatment of knee cartilage cell regeneration for degenerative arthritis patients, treatment of joint ligament and tendon injuries and low intensity of less than 100 mW / In the case of diseases that require repeated treatment for a relatively long period of time by pulsatile ultrasound, there is a problem in contact movement therapy.

This method is recommended by the KFDA safety regulations to use an ultrasound transducer in direct contact with the skin, slowly transfer the transducer, and use it at an output power of 3W / cm2 max. On the other hand, when using the stationary technique, if the ultrasound energy is exposed to the ultrasound energy of high output intensity for a certain period of time, there is a risk of burning due to heat accumulation in the tissue of the human body due to the ultrasonic energy. .

When the ultrasonic energy is irradiated to the living tissue, the amplitude potential of the molecule is generated due to the repetition of the small-sized waves, and the fluctuation and friction of the molecules generated thereby are converted into thermal energy, and the living tissue is exposed to ultrasound energy having an output intensity higher than 100 mW / , The US FDA allows for continuous use at an output power of less than 100 mW / cm 2.

In addition, an ultrasonic therapeutic apparatus using a conventional stationary technique is a method of sufficiently applying an ultrasonic wave to an ultrasonic transducer and skin, and then contacting and fixing the transducer perpendicularly to the skin to fix the body. In order to maintain the contact state, there has been a problem that it is necessary to use a protection and an RAF (Retaining and Aligning Fixture) suitable for the shape of the ultrasonic transducer and the skin surface of the human body.

In addition, due to the risk of occurrence of excessive heat at the center of the ultrasonic transducer, that is, the so-called hot spot, there is a problem that ultrasound therapy should be limited to a treatment intensity of less than 100 mW / cm 2.

Prior art of this field is disclosed in Korean Utility Model Registration No. 20-0390667 (issued on July 25, 2005) (hereinafter referred to as "prior art"), which is a "stationary ultrasonic stimulator" An ultrasonic vibrator (2) coupled to a metal vibrating part for amplifying the amplitude of the ultrasonic vibration generated from the vibrating element and for emitting heat generated by the vibration; A driving circuit unit (6) for driving the vibration element; A pad 3 attached to and supporting the rear surface of the ultrasonic vibration unit 2; And a resilient belt (4) for fixing the pad (3) to a specific body part and attaching the pad (3), wherein at least one of the ultrasonic vibration part (2) and the pad (3) is provided.

Hereinafter, embodiments of the present invention will be described in detail.

The present invention relates to a fusion therapy device combined with an ultrasonic Doppler blood flow / elasticity measurement module using a method of electronically moving and treating a driving position without moving the ultrasonic transducer.

The hybrid ultrasound therapy technique (HUST ™) is a technique for changing the irradiation position of the ultrasound waves in a plurality of ultrasonic transducer array elements according to a track set by an ultrasonic irradiation program, Which is exposed to ultrasonic energy, and is a method for electronically moving the driving position without moving the ultrasonic transducer in contact with the skin and treating the ultrasonic transducer.

 The ultrasound therapy apparatus of the present invention comprises an ultrasound pad 10 for adhering and fixing to a patient's skin and an ultrasound therapy apparatus main body 21 for controlling the ultrasound pad 10 and displaying the result thereof.

In the ultrasonic pad 10 of the present invention,

A plurality of piezoelectric elements 11 are provided so as to generate ultrasonic waves. The piezoelectric elements 11 are arranged on both sides of one side of the pad. In the middle part between the piezoelectric elements and the piezoelectric elements, An elasticity measurement probe 12 is installed and a blood flow doppler measurement probe 13 capable of measuring the velocity of blood flow is installed on one side of the elasticity measurement probe 12 to constitute an ultrasonic pad 10.

The ultrasonic pad 10 is configured to be connected to the ultrasound therapy device 20 and the data cable 30 by forming a power connection port on one side.

In addition, the main body 21 of the ultrasonic therapeutic apparatus 20 is provided with:

A signal transmitting and receiving unit 22 for supplying current to the ultrasonic pad 10 fixed to the patient's skin and transmitting and receiving signals;

A mode processing unit (24) for selectively selecting signals obtained from the signal transmission / reception unit (22);

A control unit (25) configured to process an input signal from the signal transmitting and receiving unit (22) and to control an operation signal to each component unit;

A Doppler processor 23 for outputting signals received from the signal transceiver 22 and the mode processor 24 to an image processor 26 to output a blood velocity value and an elasticity value in a cell tissue;

A display unit 27 receiving the signal value received from the Doppler processing unit 23 and outputting the received signal value to the image processing unit 26 for monitoring;

The main body 21 is constituted by an operation unit 28 that transmits the operation function of the ultrasonic therapeutic apparatus to the control unit 25. [

The Doppler processor 23 is connected to the speaker 31 so as to output a sound velocity of blood to be displayed on the display unit 27.

Reference numeral 29 in the present invention is an electric power input unit for supplying electric power to the respective components of the ultrasonic pad 10 and the ultrasonic therapeutic apparatus main body 21 so that the electric operation is performed.

In the present invention, the electrical structure to be supplied to the main body 21 of the ultrasonic pad 10 and the ultrasonic therapeutic device 20 is constituted of an electric system by a general method implemented in a general measuring device and an electronic circuit.

The piezoelectric element 11 provided in the ultrasonic pad 10 of the present invention configured as described above uses an electromechanical transducer such as an ordinary actuator, an ultrasonic sensor, or an ultrasonic transducer as an element for applying ultrasonic stimulation to the affected part of the patient.

In the present invention, the blood flow Doppler measurement probe installed on the ultrasonic pad 20 measures the velocity of the blood flow and sends the measurement signal to the Doppler processor 23. The Doppler processor 23 includes a Doppler processor And generates Doppler spectrum data from the response signal of the signal transmitting / receiving unit 22 based on the Doppler spectrum data.

The Doppler processor 23 generates Doppler spectrum data from the signal transceiver 22 based on a Doppler processor. At this time, the Doppler processing unit 23 generates data corresponding to the blood measurement value input from the patient, and transmits the data value to the image processing unit 26. The image processing unit 26 outputs the signal value to the display unit 27, , The elasticity in the cell tissue is outputted in the form of frequency so that the user can monitor the elasticity.

At this time, the blood velocity state output from the speaker 31 connected to the Doppler processing unit 23 to the display unit 27 can be received by sound.

The Doppler processing unit 23 quadrature-detects the echo received signal as a quadrature detection unit. The carrier signal used for quadrature detection has the same frequency as the fundamental frequency of the transmission ultrasonic wave.

The Doppler processing section 23 processes the quadrature-detected echo to obtain a Doppler signal, and uses a plurality of echoes obtained by a plurality of ultrasonic transmission / reception per acoustic line.

Further, the Doppler processing section 23 carries out autocorrelation calculation on the output signal by autocorrelation calculation, calculates an average flow velocity V from the autocorrelation calculation result by calculating an average flow velocity of the blood, And calculates the power PW of the Doppler signal from the autocorrelation calculation result by power calculation.

With this data processing, data representing the flow velocity V, variance T and power PW of the echo source moving in the object (patient) is obtained for each acoustic line.

These data represent the flow rate, dispersion and power of each point (pixel) on the acoustic line. The flow velocity is obtained as a component in the direction of the acoustic line and the signal sensed by the ultrasonic piezoelectric element 11, the blood Doppler measurement prober 13 elasticity measurement prober 12 is generated from a predetermined sample size in the object (patient) Sample hold the echo part. This sample holding is also referred to as range gate sampling.

The sample holding is performed for each of a plurality of echoes obtained by a plurality of ultrasonic transmission / reception of acoustic lines, and these data represent Doppler signals.

The mode processing unit 24 and the Doppler processing unit 23 are connected to the image processing unit 26. The image processing unit 26 generates a mode image, a Doppler image, and a frequency spectrum image, respectively, based on data input from the mode processing unit 24 and the Doppler processing unit 23, respectively.
The mode processing unit 24 selectively processes the signals obtained from the signal transmitting and receiving unit 22 and sends the signals to the connected processing units.

The Doppler processing unit 23 is connected to the speaker 31 which is an acoustic output unit. The Doppler processing unit 23 inputs a Doppler signal to the speaker 31. Therefore, the Doppler signal is output as an audible sound through the speaker 31 as the sound output portion.

The loudspeaker as the acoustic output unit described above may be optionally provided when the ultrasound therapy apparatus is manufactured.

That is, it may be necessary to output sound to a device such as a conventional ultrasound image output device. However, the present invention relates to an ultrasound therapy device, in which a measured value signal, such as blood laxity and blood elasticity measured from a subject, And is outputted by the display unit 27 in the normal frequency form by the display unit 26. Therefore, it is not necessary to necessarily install it, so that it can be optionally provided.

Therefore, it is an object of the present invention to provide an ultrasonic pad and a therapeutic device for physical therapy which can apply ultrasonic waves to a wide area without moving during ultrasonic treatment.

The present invention can meet the need for real-time monitoring by an ultrasonic Doppler blood flow module in the use of an ultrasonic therapeutic apparatus.

In other words, modern people are getting more dietary food due to improved living standards, and adult diseases are on the rise.

For example, adult diseases such as arteriosclerosis are also increasing due to economic development and westernization of dietary habits, and they are the leading cause of death in Koreans. Arteriosclerosis is a systemic vascular disease that invades the blood vessels of important organs such as coronary arteries, cerebral vessels, and peripheral arteries, and exhibits various clinical symptoms. These vascular diseases are highly related to each other rather than occurring separately.

For example, in patients with coronary artery disease, peripheral vascular lesions are reported to be associated with about 30%. In patients with peripheral vascular disease, the incidence of coronary artery disease is known to be about 30% to 50%.

Thus, although peripheral arterial disease is highly associated with cardiovascular mortality, the risk factors for atherosclerosis are often poorly controlled compared with patients with coronary artery disease. It is noteworthy that the diagnosis of peripheral arterial disease is not only poor because of the typical symptoms of intermittent lower limb paralysis only in about 10-30% of patients with peripheral arterial disease, It does not exceed. Elderly patients, especially those with diabetes mellitus, have a very high prevalence rate, and therefore more attention is needed in the diagnosis and treatment of peripheral arterial disease

In view of the above, in the present invention, the fusion therapy device combined with the ultrasonic Doppler flow module is suitable for the treatment of local blood flow diseases such as peripheral arterial disease patients, leg vein dysfunction patients, diabetic lower limb blood flow disorder patients, Which is the most effective treatment for the disease.

In the case of intractable diseases of such blood flow disorders, the present invention can improve the therapeutic effect by monitoring the progress of the treatment and setting the treatment direction according to the result. Doppler flowmeters are used to monitor changes in blood flow to establish a system that enables patients and physicians to check blood flow improvement effects of low-intensity pulsatile ultrasound therapy on a daily, weekly, or monthly basis, It is possible to provide a better therapeutic service.

There is also a need for real-time monitoring by an ultrasonic elasticity measurement module.

Recently, Ultrasound Elastography technology has emerged as a new imaging technology and commercialized by advanced medical device companies. Recently, many studies on the elasticity of muscles, ligaments and tendons of musculoskeletal system have been published along with the emergence of new technology have. EUS (Electro-UltraSound) is a new diagnostic method that reduces the burden of confirmation through histological examination when B-mode ultrasound imaging is applied to cancer cell tissue with harder characteristics than other tissue cells. It is becoming a target technology.

Therefore, the elasticity of the tendons, ligaments, and muscles is different according to the degree of elasticity, and the elasticity of damaged tissue is different from that of normal tissues. Therefore, information by elastic image analysis is a new means of diagnosing musculoskeletal disorders.

Ultrasonic physiotherapy can be used to treat musculoskeletal diseases and injuries. Therefore, by monitoring the characteristics of musculoskeletal tissues, the effectiveness of ultrasound therapy can be scientifically analyzed to improve the efficiency of treatment .

In the present invention, when using the ultrasonic treatment apparatus of the mixed treatment method, monitoring the therapeutic effect by observing the two-dimensional ultrasonic elasticity image (EUS) is excessive in terms of cost and effort, It is desirable to be able to monitor changes in depth by time. Thus, the effect of ultrasound treatment can be monitored in real time in the liver, at the beginning of the treatment and at important stages of the treatment, and precise analysis of the treatment outcome / course is made possible.

In this way, ultrasound therapy and treatment effects on intractable diseases and organs can be enhanced by real-time monitoring of ultrasonic physical therapy.

    Generally, an ultrasonic wave is a sound wave having a frequency of 20 kHz or more. Because ultrasound is higher in frequency than audible sound waves, it is emitted from a sound source with strong linearity.

Despite this strong linearity, ultrasonic waves do not propagate the medium because they are mechanical waves. Ultrasound medical devices have the advantage of being non-invasive and have the characteristics that they do not have ionization side effects unlike X-rays. Therefore, they are widely used for medical diagnosis and treatment, but the recognition for preventing unnecessary excessive ultrasonic exposure is increased .

The limits of the acoustic output of ultrasonic devices are presented in the World Federation for Ultrasound in Medicine and Biology (WFUMB), the US FDA, and the ECMUS (European Committee for the Medical Ultrasound Safety) in the EU. Is recommended to use less than 3W / ㎠ of effective sound intensity.

The maximum permissible upper limit for the output of an ultrasonic medical device is allowed to be up to four times the recommended value above. Special attention should be paid to the exposure time when the user exceeds the recommended use range. (Reference: "Guidelines for the Safety of Ultrasonic Medical Devices" 2007.11 Government Publication Registration No. 11-1470000-001563-01.)

In the present invention, ultrasound therapy using a stationary technique is performed in ultrasound therapy.

It has been reported that LIPUS therapy promotes bone resorption by enhancing cell membrane permeability and increasing cell activation, even if low-level ultrasound wave energy is injected into human tissues. In other words, the therapeutic effect is obvious even if the energy administered to the human body in LIPUS treatment is low. To date, the clinical and experimental effects of LIPUS on bone regeneration, bursitis, tendonitis, and tissue injury have been well documented The biophysical mechanism involved in the complex healing process is still unclear and needs further research.

Low-intensity pulsed ultrasound (LIPUS) therapy has been proven by many studies and clinical trials to have good effects on fracture fusion and bone regeneration.

Although the results of the present study and the results of clinical trials both in Korea and abroad have been published, it has been proven that the treatment is effective. However, the therapeutic parameters applied to the LIPUS treatment differ according to the study and clinical trial case. It is the present situation.

LIPUS sound waves with the same initial intensity in the treatment of bone fracture, bursitis, tendonitis, and tissue injury treat the ultrasonic wavefront, target bone tissue, or target tooth tissue The intensity or waveform in the target can vary greatly depending on the characteristics of the medium tissue present between the target tissue.

Therefore, in order to be able to transmit ultrasonic energy with appropriate therapeutic effect to the target tissue during LIPUS treatment, 1) ultrasonic intensity, 2) operating frequency, 3) radiation area of LIPUS radiation plane, 4) curvature of LIPUS radiation plane, 5 ) By optimally designing the cycle of LIPUS treatment during the entire treatment period and applying it to the treatment, the success rate of the treatment can be increased and a desirable therapeutic effect can be obtained.

It is important to consider the density (g / ㎤) of the tissue and the rate of sound transmission in the tissue. The density is as follows: density / sound velocity 0.92 / 1450, muscle 1.03 / 1590, bone 1.8 / 3360 The ultrasound attenuation is proportional to the protein content of the tissue and inversely proportional to the water content.

Blood, fat, nerves, muscles, skin, tendons, cartilage, and bones are in the order of protein content and water content, so the ultrasound attenuation increases in the same order. The attenuation coefficient (㏈ / ㎝) and the attenuation ratio (% / ㎝) of the 1 MHz ultrasonic wave in each tissue medium of the human body were 0.12 dB / ㎝ 3% in blood, 0.61 dB / The blood vessels were 1.7 dB / ㎝ 32%, skin 2.7 ㏈ / ㎝ 39%, gun 4.9 ㏈ / ㎝ 59%, cartilage 5.0 ㏈ / ㎝ 68% bone 13.9 dB / ㎝ 96% The density of the tissue, the viscosity of the tissue, the acoustic impedance of the tissue, the fat and moisture content, the angle of incidence, the angle of incidence, the reflection, the scattering, and the degree of refraction.

In other words, ultrasonic waves of the same intensity can vary greatly depending on the attenuation characteristics of the intermediate tissues and the distance between the sound waves and the tissues. Therefore, optimal treatment effects can be obtained by applying optimal treatment parameters according to the patient's condition This can increase the success rate of treatment.

The LIPUS human-type ultrasound therapy system can be developed as a model that can be used to continuously update the reliability of the LIPUS-related models and the updated knowledge of the LIPUS treatment results and the prediction results of the LIPUS treatment results using the treatment results .

In addition, the LIPUS test verifier composed of a LIPUS output transmitter, a LIPUS receiver, and a signal processing device is developed and operated, so that the reliability of LIPUS technology can be improved in designing and developing new therapeutic products.

There have been many reports that millions of fractures occur worldwide every year and fracture sites are treated with low intensity ultrasound to induce callus formation and promote fracture healing. However, systematic system for optimizing LIPUS treatment and low intensity ultrasound Wearable ultrasonic medical devices for implantation into the human body have not been developed globally. This technology development project is to develop a systematic system to optimize LIPUS treatment including LIPUS (Low Intensity Ultrasound) ultrasonic treatment device for fracture joint and fracture which can be applied to various parts of human body fracture using advanced science and technology .

It has been reported that LIPUS therapy promotes bone resorption by enhancing cell membrane permeability and increasing cell activation, even if low-level ultrasound wave energy is injected into human tissues.

In other words, the therapeutic effect is obvious even if the energy administered to the human body in LIPUS treatment is low. Up to now, clinical and experimental evidence of bone regeneration has been demonstrated by LIPUS therapy, but the biophysical mechanism involved in the complex healing process is still unclear and needs further study have.

Although the results of the present study and the results of clinical trials both in Korea and abroad have been published, it has been proven that the treatment is effective. However, the therapeutic parameters applied to the LIPUS treatment differ according to the study and clinical trial case. It is the present situation.

According to data from 2004 to 2008, the number of cases of osteoporotic fractures over 50 years of age increased by 3.8% each year to 220,000 in 2005, 230,000 in 2006, 230,000 in 2007 and 240,000 in 2008 , And about 77% of osteoporotic fractures occurred in women. The highest incidence of fracture was in the spine (95.6), wrist (42.5), ankle (19.7), hip (15.1), upper arm (8.0), and clavicle (6.8) Respectively. By sex, as of 2009, the number of fractured patients was 1 million 5658 men and 763,399 women, 30% more than women. The annual average growth rate for five years was 3.5% for males and 5.5% for females.

With the increasing number of patients treated for fracture due to aging population, the development of fracture treatment technology is important in forming a socially healthy welfare society. In the last decades, much progress has been made in the technique of fracture treatment, but patients with fractures of 5-10% are showing delayed junctions. Significant patients in this delayed-junction group are treated if they can not be treated until 9 months and are classified as non-union patients.

Formal clinical studies have reported that 80% to 90% of fracture splicing successes were obtained when LIPUS treatment was administered to this non-joint patient. The development of technology that can increase the success rate of LIPUS treatment is very important not only economically but also social welfare because it causes considerable social cost as well as my own misfortune in case of failure of fracture connection.
