The structure and operation of the present invention shown in the drawings and described by the drawings are described as at least one embodiment, and the technical ideas and the core structure and operation of the present invention are not limited thereby.

FIG. 1 is an exploded perspective view showing a ball-borne external shock wave therapy apparatus according to the present invention, and FIG. 2 is a sectional view showing the ball-borne external shock wave treatment apparatus shown in FIG.

The ball-borne external shock wave therapeutic apparatus of the present invention has an outer case (not shown) formed in a Gun shape in a manner using impact energy using compressed air.

As shown in FIGS. 1 and 2, the ball-borne external shock wave therapeutic apparatus of the present invention includes a solenoid valve 10 for controlling the discharge of the stored compressed air An actuator 20 having an air nozzle 22 communicating with the solenoid valve 10 and a cylinder 30 through which the compressed air discharged from the solenoid valve 10 moves A muffler 50 installed on the outer circumferential surface of the cylinder 30 and a muffler 50 mounted on the outer circumferential surface of the cylinder 30, And an impact transducer 60 for transmitting a shock wave due to a direct impact force generated thereon.

An impact transducer cap 80 for fixing the impact transducer 60 is provided at the tip of the housing 70. The impact transducer cap 80 may be screwed and disassembled.

The solenoid valve 10 has a structure in which a plurality of coils are wound, and the valve is opened or closed according to on / off of the power source to control the discharge of the stored compressed air. A driving means (not shown) is connected to the solenoid valve 10. The driving means may be a hydraulic pump, a pneumatic pump, or an electromagnetic pump.

In the actuator 20, a flow path 21 through which the compressed air discharged from the solenoid valve 10 passes is formed. As shown in FIG. 2, the flow path 21 may be formed at a right angle to an outer case (not shown) formed in a gun shape.

The actuator 20 may be provided with an air nozzle 22 for connecting the solenoid valve 10 and the actuator 20 to each other.

A metal-made exerciser 40 is accommodated in the cylinder 30 through which the compressed air passes. The exerciser 40 in the present invention reduces friction with the cylinder 30, And is characterized in that it is formed as a structure that can be formed.

That is, in the exerciser 40 of the present invention, a plurality of concavities and convexities 42 are formed on the outer circumferential surface to reduce the friction with the cylinder 30.

The projections and depressions 42 may be formed, for example, in a spiral shape, or may be formed by successively forming ring-shaped projections in a row. The irregularities 42 greatly reduce the contact area with the inner circumferential surface of the cylinder 30, thereby reducing the friction with the cylinder 30. Therefore, energy loss due to friction when the exerciser 40 flows in the cylinder 30 can be reduced, and the impact energy of the shock wave can be prevented from being reduced.

The exerciser 40 may be made of a variety of materials other than the metal material, and the inclined surface 44 is provided at the distal end portion and the concave groove 46 is formed at the rear end portion.

On the other hand, at the rear end of the cylinder 30, a magnet body 24 for magnetically pulling the exerciser 40 is provided. The magnet body 24 is formed at the rear end of the cylinder 30 and has a ring shape having a hole through which the compressed air can pass.

A cushioning member 26 is provided between the magnet body 24 and the cylinder 30 to mitigate noise and shock caused by contact between the exerciser 40 and the magnet body 24.

The buffer member 26 is formed with a hole through which the compressed air can pass, and an inclined groove 26a is formed on a surface of the moving member 40 side.

Meanwhile, the rear end of the exerciser 40 is formed with a concave groove 46 having a concave shape so as to be well impacted by the compressed air. Therefore, a space 32 in which air is received is formed between the buffer member 26 and the recessed groove 46 of the exerciser 40.

As described above, since the space 32 in which the air is received is formed behind the exerciser 40, the ball-borne external shock wave therapy apparatus of the present invention can prevent the exerciser 40 from moving backward The forward movement of the exerciser 40 can be maximized when the compressed air is discharged due to the air being always behind the exerciser 40. In other words, And has a stable effect.

The buffer member 26 is preferably made of silicon.

In the meantime, the ball-borne external shock wave therapy apparatus of the present invention includes a fixing member 90 for holding the exerciser 40 when the exerciser 40 returns due to a repulsive effect due to an impact after the shock wave is generated. The fixing member 90 may be a ball plunger for fixing the exerciser 40 on the inner circumferential surface of the cylinder 30.

It is preferable that the distal end of the exerciser 40 is provided with an inclined surface 44 so that the fixing member 90 can easily hold the exerciser 40.

Since the exerciser 40 has a substantially cylindrical shape, the inclined surface 44 may be formed by cutting the outer peripheral surface of the distal end of the exerciser 40, as shown in an enlarged view of FIG. That is, the distal end edge of the exerciser 40 is cut so as to form the inclined surface 44.

The inclined surface 44 facilitates the engagement with the fixing member 90 when the exerciser 40 is returned to the rear.

In addition, the fixing member 90 may be installed to be able to engage with the protrusions and depressions 42 of the exerciser 40 according to the installation position. That is, the fixing member 90 is not hooked on the inclined surface 44, but the fixing member 90 is engaged with the concave and convex portions 42.

Even in this case, it is ensured that the exerciser 40 is fixed to the initial position due to the fixing member 90.

In the present invention having such a configuration, the repulsive force due to the shock after the generation of the shock wave and the air compressed to the outside of the cylinder 30 cause the exerciser 40 to move backward, and when the internal pressure reaches a certain level, The valve 10 is opened to allow the compressed air to escape rearward and the exerciser 40 is fixed by the fixing member 90 and the magnet body 24 provided at the initial position.

On the other hand, a muffler 50 having a plurality of air tanks 52 and 54 is installed on the outer circumferential surface of the cylinder 30. The muffler 50 is a component that fixes the cylinder 30 by contacting the outer circumferential surface of the cylinder 30, and thus has a substantially cylindrical shape.

For example, a gel for an ultrasonic wave, a paste material, or a vaseline.

The compressed air is discharged through the solenoid valve 10 so that the exerciser 40 is moved forward in the cylinder 30 by operating the driving means (not shown) And the forwardly moved exerciser 40 collides with the rear surface of the impact transducer 60, so that the shock wave is transmitted into the biological tissue of the skin.

The present invention minimizes the contact area with the cylinder 30 when the exerciser 40 moves inside the cylinder 30 by forming the concavity and convexity 42 in the exerciser 40 to prevent the energy loss of the exerciser 40 can do.

Then, when the solenoid valve 10 is opened and compressed to a certain degree of internal pressure, the exerciser 40 moves backward due to the repulsive action by the impact and the air compressed outside the cylinder 30, And the movable member 26 is fixed to the armature 40 in the initial position by the magnetic force of the magnet body 24 and the fixing member 26.
