The present invention relates to a cylinder for extracorporeal shock wave therapy that treats shock wave energy in a lesioned area, and more specifically, has an elastic member or a second compressed air supply pipe in front of an inner pipe tube, and a brake groove in the shock wave generator. At the same time, the brake protrusion is formed on the inner edge of the inner pipe and the inner side of the inner pipe tube, so that the shock wave generator stably fixes the shock wave generator when the initial position of the shock wave generator made of metal containing mild steel or iron (Fe) is fixed. The present invention relates to a cylinder for an extracorporeal shock wave therapy device, which can maintain the occurrence of uniformly and utilize the inlet pressure of compressed air as reliably and efficiently as possible.

Baseball, football, golf, swimming, and marathon runners, who have been forced to excessively exercise excessively for a long time, often inflamed or damaged joints, tendons, and ligaments, as well as suddenly excessive exercise or excessive work. In addition to general people who feel muscle pain, extracorporeal shockwave therapy is a simple way to cure diseases and chronic pain that are not easily improved by conservative therapy such as physiotherapy, drug therapy, or herbal therapy without surgery.

This shock wave therapy regimen delivers shock waves into the body by bringing the shock wave therapy device into contact with the painful procedure, promoting remodeling of blood vessels, descaling tendons, and stimulating or reactivating the tendon and surrounding tissues, The result is an effective treatment that can reduce pain and improve function.

The shock wave therapy device used in such a shock wave therapy device uses a compressed air supply pipe for discharging compressed air into a cylinder, a shock wave generator projected to the front by discharge of compressed air into the cylinder, and a shock energy generated by a collision with the shock wave generator. It consists of shock wave carriers that deliver to the affected part of the human body.

Here, the compressed air is a separate air compressor that compresses and stores the air until it reaches a predetermined pressure, an air regulator that supplies air by adjusting the discharge pressure required by the user, and the amount of compressed air required as needed. The electric solenoid valve that discharges the air is sprayed from 1 to 10 times per second, or every time the user requires. The shock wave generator generates one compressed air. It is fired forward and collides with the shock wave carrier to generate shock wave energy. For the next launch, the shock wave generator must be quickly returned to its initial position before launch.

Accordingly, when the compressed air is injected again, the above process is repeated, so that the impact energy required by the user can be applied to the lesioned area at the desired intensity and force (Hz).

However, it is quite difficult for the shock wave generator to be returned to the initial position accurately and quickly simply by relying on the repulsive force due to the collision with the shock wave carrier.

Depending on whether the direction of the muzzle of the treatment device is toward the sky or the ground where gravity is heavily influenced, or the horizontal direction of gravity is inevitable, the location of the shock wave generator made of metal with considerable mass becomes uneven. .

This will make it difficult to expect a uniform force (force) and speed (Hz) of the shock wave, which will cause a lot of difficulties in the procedure, even if some initial position return is possible, stable the shock wave generator until just before the next air injection I need something that can be fixed.

The present invention has been made to solve the above problems, having an elastic member or a second compressed air supply pipe in the front of the inner pipe pipe and forming a braking groove in the shock wave generator, and at the same time the braking protrusion on the inner combustion of the inner pipe pipe By stably fixing the shock wave generator upon returning to the initial position of the shock wave generator, which is made of mild steel or iron (Fe), the impact energy is kept uniform and the inlet pressure of the compressed air is maximized.

Braking grooves are formed on the outer edge of the shock wave generator in the width direction, and a brake protrusion is protruded at a predetermined point of the inner portion of the inner portion of the inner end of the inner pipe tube so that the shock wave generator is braked due to friction between the brake groove and the brake protrusion.

Here, the return means is an elastic member interposed between the shock wave generator and the shock wave carrier of the inner pipe pipe so as to smoothly return to the initial position by the restoring force after the shock wave generator collides with the front of the inner pipe pipe and communicates with the compressed air. It is preferable that the second compressed air supply pipe is introduced into the internal pipe pipe to smoothly return the shock wave generator to the initial position.

Hereinafter will be described in detail with the accompanying drawings for the cylinder structure for extracorporeal shock wave treatment device according to the present invention.

(Example 1)

1 is an exploded perspective view of a cylinder for extracorporeal shock wave treatment device according to an embodiment of the present invention, Figure 2 is a cross-sectional view of Figure 1, Figure 5 is an enlarged view of portion A of Figure 1, Figure 6 is a portion B of Figure 1 7 is an enlarged view, and FIG. 7 is a perspective view of a shock wave generator according to the present invention, and FIG. 8 is a perspective view of a shock wave generator that is deformable.

Referring to the drawings, the cylinder according to the present invention is largely composed of a cap 11 and the body 12 and is inserted into the housing 10 having a hollow, the cap 11 of the housing 10, the predetermined portion is the outside A hollow inner pipe tube 30 protruding into the shock wave carrier 20 and inserted into the housing 10 and in communication with the first compressed air supply pipe 60 on one side thereof and in close contact with the shock wave carrier 20 on the other side thereof. And a shock wave generator 40 which is inserted into the inner pipe pipe 30 and is discharged forward by the compressed air discharged to the first compressed air supply pipe 60 to collide with the shock wave carrier 20, and the inner pipe. Is coupled to the front of the tube 30 is made of a return means for allowing the shock wave generator 40 collided with the shock wave carrier 20 to return to the initial position.

The return means according to the present embodiment is interpolated in the inner pipe tube 30 and interposed between the shock wave generator 40 and the shock wave carrier 20 so that the shock wave generator 40 returns to its initial position by the restoring force after the collision. It adopts an elastic member 80 to apply a predetermined external force to be able to.

The elastic member 80 is located between the shock wave generator 40 and the shock wave carrier 20 in the inner pipe pipe 30, the shock wave generator 40 is contracted to a certain length when collided with the shock wave carrier 20 It acts to push the shock wave generator 40 back by the restoring force.

Accordingly, the shock wave generator 40 is easily returned to the initial position, and the time interval for returning to the initial position is constant regardless of the external position of the cylinder.

Meanwhile, the housing 10 includes a cap 11 and a body 12, and the cap 11 accommodates the shock wave carrier 20, and the body 12 accommodates the inner pipe tube 30 and the bushing 70. do.

At one end of the body 12, a first compressed air supply pipe 60 into which compressed air is introduced is introduced, which communicates with an inner pipe tube 30 inserted into the body 12.

In addition, the body 12 and the cap 11 may form the housing 10 integrally without a separate configuration, but each thread is formed by forming a screw thread on the inner and outer edges.

In this way, the body 12 and the cap 11 are designed to be screwed together to facilitate replacement and repair due to damage of internal parts that may occur during use. In order to smoothly perform the operation such as exchange coupling), the present invention is not limited to this, of course.

On the other hand, the shock wave carrier 20 accommodated in the cap 11, one side protrudes, the shock wave energy generated when the shock wave generator 40 in the inner pipe pipe 30 to be described later collides with the shock wave carrier 20. It is delivered to the affected part of the patient with the lesion.

This is delivered by direct contact of the projecting portion of the shock wave carrier 20 to the affected area. In order to prevent the loss of the shock wave energy, which is in contact with the outside of the thin clothing, directly to the bare skin, or transmitted, the cream of gel form is applied to the affected area. After applying a shock wave.

Since the shock wave generator 40 and the shock wave carrier 20 may be damaged due to frequent collisions, the shock wave generator 40 and the shock wave carrier 20 have to be excellent in strength. In the case of the shock wave generator 40, in order to increase the impact force due to the instantaneous acceleration, the specific gravity per unit volume is relatively high. Higher metal material selection would be appropriate.

In addition, in the case of the shock wave carrier 20, unlike the shock wave generator 40, since the parts are to be impacted at a fixed position, the selection of a material resistant to impact should be prioritized rather than the specific gravity per unit volume. It would be desirable to select a high strength synthetic resin, such as acetal, rather than a metal-based material to prevent breakage due to collision between the two.

In addition, if the material is excellent in strength and can withstand frequent shock, it can be used as the shock wave carrier 20 according to the present invention.

Meanwhile, a plurality of first rubber rings 21 and second rubber rings 22 are coupled to the shock wave carrier 20 at an outer edge of a predetermined point, and the first rubber rings 21 are positioned inside the cap 11. By inducing the shock wave carrier 20 to be located at the correct center without biasing to one side, so that the face and the face exactly collides with the shock wave generator 40, the loss of shock wave energy to the maximum It is designed to maximize the shock wave transmitted to the affected part by reducing it, and smoothly inside the cap 11 as much as the gap generated by the minute compression and relaxation of the second rubber ring 22 during the impact of the shock wave generator 40. To make it move.

When the second rubber ring 22 collides with the shock wave carrier 20 at a very high speed, the second rubber ring 22 generates minute compression and relaxation of the second rubber ring 22 at about the same speed. This is to allow the impact energy to be smoothly transmitted to the affected area by the momentary tremor as much as the minute gap at this time.

In addition, the shock wave generator 40 is also intended to prevent damage to the parts that may be caused by the impact wave carrier 20 directly collides with the cap step 11a in the cap 11 during the impact.

Meanwhile, the inner pipe tube 30 is fixedly installed in the housing 10 by coupling the bushing 70 to the outer edge of a predetermined point, and one side communicates with the first compressed air supply pipe 60 so that the compressed air is introduced therein. The other side is configured to be in close contact with the shock wave carrier 20 so that the shock wave generator 40 provided in the inner pipe tube 30 collides with the shock wave carrier 20 to generate impact energy as the compressed air is introduced. .

As the material of the inner pipe tube 30, it is preferable that the copper pipe or stainless steel material having excellent durability and corrosion resistance, but the present invention is not limited thereto.

In addition, the bushing 70 is composed of a first bushing 71 coupled to the outer edge of the inner pipe tube 30, the second bushing 72 coupled to the outer edge of the inner pipe tube 30, Through-holes 71a and 72a are formed in the first bushing 71 and the second bushing 72 so that one side portion and the other side portion communicate with each other so that the compressed air introduced into the inner pipe tube 30 can be discharged to the outside. It is composed.

In addition, the first discharge hole 31 is formed at a point spaced a predetermined distance from the front end of the inner pipe pipe 30 in order to quickly discharge the compressed air drawn into the inner pipe pipe 30 to the outside, The second discharge hole 32 for discharging the remaining air is formed at the point in contact with the shock wave carrier 20 so that the impact energy is not reduced.

The configuration of the through holes 71a, 72a, the first discharge hole 31, and the second discharge hole 32 is such that the shock wave generator 40, which is projected forward by the compressed air, is smoothly provided with the shock wave carrier 20. It is an essential technical configuration to collide and at the same time smoothly return to the initial position.

On the other hand, a brake groove 41 is formed at the outer edge of the shock wave generator 40, which is moved to the rear side by the restoring force of the elastic member 80 after colliding with the shock wave carrier 20, and is rearward of the inner pipe tube 30. The brake protrusion 50 is protruded at a predetermined portion of the internal combustion portion, so that the shock wave generator can stop at an initial position due to friction between the brake groove 41 and the brake protrusion 50.

The brake groove 41 is to increase the frictional force with the brake protrusion 50, the width of the brake groove 41 is more effective than the longitudinal direction of the shock wave generator 40.

The deformable braking groove 21 may be formed diagonally in both directions and may be formed diagonally in one direction.

In addition, the material of the braking protrusion 50 is preferably a synthetic resin material having high elasticity and high strength, and may be densely formed inside the inner pipe tube 30 to increase friction with the braking groove 41.

In the conventional case, the shock wave generator 40 is returned to the rear by a simple repulsive force due to the collision with the shock wave carrier 20, but this is dependent on the direction in which the cylinder is directed (sky, horizontal, ground). Due to the influence of gravity due to mass, its return point and position were irregular.

The resulting impact energy was also irregular in size and was not suitable for treatment.

In addition, as the returned shock wave generator 40 moves forward again by the repulsive force before the next introduction of the compressed air, the shock wave generator 40 decreases the stroke distance and thus the instantaneous acceleration. Due to the problem that a sufficient amount of shock wave energy could not be obtained, this problem is improved according to the configuration of the braking groove 41 and the braking protrusion 50 according to the present invention.
