The present invention relates to a cylinder structure for an extracorporeal shock wave therapy device that treats shock waves by transferring shock wave energy to a lesioned area. More specifically, the shock wave generator can be quickly returned to an initial position by coupling a permanent magnet to a predetermined point of the outer pipe. The present invention relates to a cylinder structure for an extracorporeal shock wave treatment device capable of easily maintaining the generation of shock wave energy and maximizing the shock wave generation using the discharge force of the compressed air as it is fixed at the same time.

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 treatment device used in the shock wave therapy therapy is a compressed air supply pipe for discharging compressed air into the cylinder and a shock energy generated by a collision with the shock wave generator emitted to the front by the discharge of the compressed air in the cylinder and the shock wave generator It consists of a shock wave carrier that delivers 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 air solenoid valve that discharges the air is sprayed from 1 to 10 times per second or whenever necessary by the user. 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 return 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 which is heavily influenced by gravity, or when the influence of gravity is normal, the location of the shock wave generator made of metal with considerable mass will be uneven. .

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

The present invention has been made to solve the above problems by combining the permanent magnet at a certain point of the outer pipe of the inner pipe tube to quickly return the shock wave generator to the initial position by using the magnetic force generated continuously and uniformly in the permanent magnet. At the same time, it is fixed stably so as not to deviate from its position, so that the shock wave energy generation is kept constant at the desired intensity (Force) and speed (Hz), and the cylinder structure for extracorporeal shock wave therapy device that can make maximum use of the discharge power of the compressed air. The purpose is to provide.

The present invention has the following features to achieve the above object.

The present invention is a cylinder structure for an extracorporeal shock wave treatment device, comprising: a housing having a hollow and a cap; A shock wave carrier embedded in a cap of the housing; A hollow inner pipe tube inserted into the housing and in communication with a compressed air supply pipe on one side and in close contact with the shock wave carrier on the other side; A shock wave generator which is inserted into the inner pipe pipe and is discharged forward by the compressed air discharged to the compressed air supply pipe and collides with the shock wave carrier; And a permanent magnet coupled to an outer side of the inner pipe tube and pulled by the magnetic force of the shock wave generator collided with the shock wave carrier to be positioned at a desired position.

In this housing, a bushing coupled to the inner pipe tube outer edge and closely attached to the housing inner edge is installed in the housing to fix the inner pipe tube. The bushing includes a first bushing coupled to the outer edge of the inner pipe tube and an inner pipe tube. It is composed of a second bushing coupled to the outer edge of the rear portion, the first bushing and the second bushing is formed with a through hole communicating one side and the other side so that the compressed air drawn into the inner pipe pipe can be discharged to the outside It is composed.

In addition, the inner pipe pipe, the first discharge hole is formed at a point spaced from the front end of the inner pipe pipe in order to quickly discharge the compressed air drawn into the inner pipe pipe to the outside, the shock wave carrier and the shock wave generator A second discharge hole for discharging the remaining air is formed at the point of contact so that the shock wave energy is not reduced, the permanent magnet is coupled to the outer pipe of the inner pipe pipe between the first bushing and the second bushing, but is in close contact with the second bushing. .

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.

1 is an exploded perspective view of a cylinder structure for an extracorporeal shock wave therapy device according to the present invention, Figure 2 is a cross-sectional view of a cylinder structure for an extracorporeal shock wave therapy device according to the present invention, Figure 3 is an enlarged view of a portion A of FIG. It is an enlarged view of part B of FIG.

Referring to the drawings, the cylinder structure according to the present invention is largely composed of a cap 11 and a body 12 and is inserted into the housing 10 having a hollow and the cap 11 of the housing 10, but a predetermined portion is outside. And a hollow inner pipe tube 30 protruding into the shock wave carrier 20 and inserted into the housing 10 and in communication with the compressed air supply pipe 60 on one side and in close contact with the shock wave carrier 20 on the other side; Shock wave generator 40 which is inserted into the inner pipe pipe 30 and is discharged forward by the compressed air discharged to the compressed air supply pipe 60 and collides with the shock wave carrier 20, and the inner pipe pipe 30 The shock wave generator 40 is coupled to one side of the outer periphery is made of a permanent magnet 50 that is pulled by the magnetic force to the exact position to the target position.

Wherein the housing 10 is composed of a cap 11 and the body 12, the cap 11 to receive the shock wave carrier 20, the body 12 to accommodate the inner pipe pipe 30 and the bushing 70 do.

At one end of the body 12 is compressed air supply pipe 60 through which compressed air is introduced, which is in communication with the 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.

As such, the body 12 and the cap 11 are designed to be screwed to separate the cap 11 according to the treatment area and the purpose of the replacement and repair, and the treatment part and the purpose of the internal parts that may be damaged during use. In order to smoothly perform the operation, such as exchange of the combination, of course, the present invention is not limited thereto.

A coupling hole 10a is preferably formed at the rear end of the body 12 to fix the bushing 70 to be described later.

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 or directly to the bare skin, or transmitted, After applying the cream, a shock wave may be applied.

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. High metal-based material selection will be inevitable, and in order to return the initial position of the shock wave generator 40 due to the magnetic force of the permanent magnet 50, mild steel or iron (Fe) containing the influence of the magnetic force may be included. Alloyed material may be suitable.

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. In order to prevent breakage due to collision between each other, it is preferable to select a high-strength synthetic resin such as acetyl rather than a metal-based material.

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 oil ring 21 is located inside the cap 11. By inducing the shock wave carrier 20 to be positioned at the correct center without biasing to one side, so that the face and face collide precisely when colliding with the shock wave generator 40, the loss of shock wave energy is maximized. 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 component damage that may be caused by the impact wave carrier 20 directly collides with the stepped portion (11a) of the inside of the cap 11 during the impact.

On the other hand, the inner pipe pipe 30 is a bushing 70 is coupled to the outer edge of a predetermined point fixedly installed in the housing 10, one side is in communication with the compressed air supply pipe 60 is configured to draw the compressed air into the inside In addition, the other side is in close contact with the shock wave carrier 20 and configured to generate impact energy by colliding with the shock wave carrier 20 when the shock wave generator 40 provided in the inner pipe tube 30 comes in contact with the compressed air.

As the material of the inner pipe tube 30, it may be preferable that the copper pipe or stainless steel material is excellent in durability and corrosion resistance.

In addition, the bushing 70 is composed of a first bushing 71 coupled to the outer periphery of the inner pipe tube 30, and a second bushing 72 coupled to the outer edge of the rear portion 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 compressed air introduced into the inner pipe tube 30 may be discharged to the outside. It is configured to be.

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.

In addition, as a core technical feature of the present invention is coupled to the outer periphery of the inner pipe pipe 30 between the first bushing (71) and the second bushing (72) is coupled to be in close contact with the second bushing (72) and the shock wave carrier (20) Of the permanent magnet 50, which serves to stably fix the shock wave generator 40 at the same time as the shock wave generator 40 staying in place after the collision with the initial position. There are two main roles as follows.

First, after the initial introduction of the compressed air, the shock wave generator 40 can be returned to the initial target position quickly and accurately after the initial collision with the shock wave medium 20 for the next collision. It is to generate a manpower (magnetic force), and secondly, the shock wave generator 40 returned to the initial position is to secure the stably waiting until the next compressed air is introduced.

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, the return point was irregular.

The impact energy generated by this was also irregular in size and was not suitable for the 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 can not be obtained a sufficient amount of shock wave energy, this problem is improved by the provision of a permanent magnet according to the present invention.

When the magnetic strength of the permanent magnet 50 is too high, a force that pulls the shock wave generator 40 to collide with the shock wave carrier 20 from the rear is large to reduce the impact energy, and if too weak, the shock wave is generated. It is not possible to quickly return the sieve 40 to its initial position.

In consideration of this point, the size of the permanent magnet 50 and the strength of the magnetic force should be appropriately adjusted.

In addition, in order to quickly and accurately return the shock wave generator 40 to the initial position by using the magnetic force of the permanent magnet 50, that is, the point corresponding to the maximum travel distance (Stroke) that the shock wave generator 40 can move, that is, shock wave The point where the generator 40 collides with the shock wave carrier 20 must be located within the range of the magnetic force of the permanent magnet 50.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. .

Therefore, the true technical protection scope of the present invention should be defined by the technical spirit of the appended claims.

As described above, the present invention uses a magnetic field (magnetic force) of a permanent magnet by coupling a permanent magnet to a predetermined point of the outer edge of a pipe tube, and initially sets a shock wave generator, which is an alloy material containing mild steel or iron (Fe), to an initial position. By returning quickly and accurately, and stably fixing the shock wave generator returned to the initial position, the generation of impact energy can be kept uniform and the inlet pressure of the compressed air can be used stably and efficiently.

In addition, through the second discharge hole, the impact energy due to the compression of the remaining air, which may occur when the shock wave generator collides with the shock wave carrier, increases the impact energy, and the internal pipe through the through hole of the first discharge hole and the bushing. By discharging the compressed air drawn into the pipe to the outside quickly and smoothly, the shock wave generator helps to return to the initial position quickly and accurately.
