【発明の詳細な説明】 〈産業上の利用分野〉 本発明は、例えば超音波治療器の素子パッドに関する。[Detailed description of the invention] <Industrial application field> The present invention relates to, for example, an element pad for an ultrasonic treatment device.

凝り等の治療に有効であることが知られている。<Prior art> In general, an ultrasonic treatment device applies an element pad equipped with an ultrasonic oscillator to an affected area or acupuncture point of the human body, and irradiates the five colored areas or acupuncture points with ultrasonic waves from the ultrasonic oscillator. It is a medical device that obtains therapeutic effects through this process, and is known to be effective in treating lower back pain, neuralgia, and shoulder stiffness.

た構造の素子パッドを使用して治療を行っている。In this type of medical device, if there is an air layer between the element pad and the human skin, the ultrasonic transmission rate to the human body will be poor. Treatment may be performed by applying olive oil, or a member 31 for protecting the ultrasonic oscillator 2 as shown in FIG.
For this purpose, treatment is performed using an element pad having a structure provided with an ultrasonic medium 33 that has high adhesion to the skin of the human body.

非常に弱く充分な治療効果を得ることができない。<Problems to be Solved by the Invention> By the way, according to the element pad having the structure shown in FIG. 3, the ultrasonic waves generated by the ultrasonic oscillator 2 pass through the acoustic matching layer 2a and propagate straight or radially. Furthermore, the intensity decreases as the distance from the ultrasonic oscillator increases. For this reason,
For example, at acupuncture points deep within the human body, the intensity of the ultrasonic waves that reach them is very weak, making it impossible to obtain a sufficient therapeutic effect.
本発明の目的は、超音波を人体等の所望の部位に収束す

It is characterized by being made of a material and having one of the protection member 1 and the ultrasonic medium 3 protrude inside the other.

伝播速度の遅い媒体（保護部材１）から速い媒体（超音
波媒体３）に入射するので、両者の境界面において屈折
し、しかもその境界面が凸面であることから収束する。For example, if the protective member 1 is formed of a material whose sound wave propagation velocity is slower than the ultrasonic medium 3 and the protective member 1 is raised in the ultrasonic medium 3, the ultrasonic waves from the ultrasonic oscillator 2 are Since the sound waves enter from a medium with a slow propagation speed (protective member 1) to a fast medium (ultrasonic medium 3), they are refracted at the interface between the two, and since the interface is a convex surface, they converge.

面に密着して超音波媒体３が形成されている。An ultrasonic oscillator 2 including an acoustic matching layer 2a is disposed inside the oscillator protection member 1. Further, the ultrasonic propagation portion of the oscillator protection member 1 is formed into a convex surface, and the ultrasonic medium 3 is formed in close contact with the convex surface.

よって形成されている。The oscillator protection member 1 is made of silicone rubber, and its sound wave propagation velocity is about 1000 m/sec. On the other hand, the ultrasonic medium 3 has a sound wave propagation velocity of about 15

That is, an acoustic convergence lens is formed on the path of the ultrasonic waves. Here, the depth d at which the ultrasonic waves converge within the human body M can be determined arbitrarily by appropriately selecting the materials of the oscillator protection member 1 and the ultrasonic medium 3 that form the acoustic lens, and the diameter of the acoustic lens. Can be set to

レンズを形成できる。In addition, when the oscillator protection member is formed of a material whose sound wave propagation speed is higher than that of the ultrasonic medium, the oscillator protection member 21 is formed into a concave shape as shown in FIG. An acoustic convergence lens can be formed by bringing the acoustic wave medium 23 into close contact.
