Description

Massager

The invention relates to medical equipment, in particular to massagers, and can be used as a means for reflex effects on the human body for therapeutic and prophylactic purposes.

Well-known massagers, made in the form of several rigidly interconnected massage heads, with which they act on the user's body.

An example of such massagers is a massager known by the patent of the Russian Federation for the invention Ns 2220698, IPC A61 H 15/00, priority date 07/13/2001, which is selected as an analogue. The massager contains four rigidly interconnected massage heads located at the vertices of the tetrahedron. The faces of the tetrahedron are tangent to the three corresponding massage heads, that is, the corresponding massage heads are located in the planes of the corresponding faces of the tetrahedron. Any of the faces of the tetrahedron (the plane of the face of the tetrahedron) can be selected as working when the user’s body is affected by massage heads located in the plane of the selected face. At least one of the massage heads is made with at least one protrusion, the axis of which is perpendicular to one of the faces of the tetrahedron. The protrusions may have a spherical, or cylindrical, or conical, or other spatial shape. The protrusions can be made in the form of an insert embedded in the head made of a material different from the head material: metal or alloy of metals, magnetic material, natural mineral, in the form of a metal insert with a partial coating, the electrochemical potential of which differs from the electrochemical potential of the material insertion. Having chosen one of the faces of the tetrahedron as the working one (that is, by choosing the corresponding heads with corresponding protrusions), they apply it to the user's body and, moving the massager, perform a massage procedure.

Common signs of the proposed solution and the analogue are: a massager made in the form of a massage unit containing at least three interconnected massage heads.

The specified massager provides a uniform distribution of the pressing force of the massager between the massage heads (statically defined three-support structure) and the adaptation of the massage heads to the curvature of the user's body. However, the impact on the user's body is carried out only by three massage heads, which limits the effectiveness of the massager. A massager was selected as a prototype (patent of the Russian Federation for invention Ns 2270659, IPC A61 H 15/00, application filing date 08/26/2004), which contains a body with a handle on the upper side of the body and replaceable massage units mounted on the back of the body. Each massage unit contains a spherical massage head with a shank. On the lower side of the body holders of shanks of massage units are made in the form of longitudinally oriented holes located obliquely to the longitudinal axis of the massager. The shanks of the massage units are made with annular grooves, with which the locking disk, spring-loaded relative to the body, interacts as a means of fixing the shanks in the body holders. Massage units are fixedly fixed in holders and arranged in a circle, massage heads are located in one horizontal plane. The number of massage nodes is six, but in principle their number can be any. Massage heads are made in the form of hermetic containers filled with some known refrigerant or substance with high heat capacity. On the massage heads, protrusions of various shapes can be made to enhance the massage effect.

Before the massage, one part of the massage elements is pre-cooled, and the other, on the contrary, is heated. After that, the massager is assembled. The shanks of the massage units are inserted into the holders and fixed with a locking disc. During the massage, the device with the necessary effort is pressed against the surface of the corresponding part of the body and the massager is moved in different directions. In this case, parts of the body are simultaneously subjected to mechanical and rhythmically changing multi-temperature effects.

Common features of the analogue and the claimed solution are: a massager containing a body, several massage nodes mounted on the body with the possibility of impact on the user's body.

The solution according to the prototype is characterized by motionless fixing of a plurality of massage nodes with massage heads on the body of the massager, which are in contact with the surface of the massaged area of the body (with which the massager rests on the surface of the body) when performing massage procedures. It is well known that a mechanical system made with more than three supporting elements is a statically indeterminate system (a statically indeterminate system is one that has unnecessary support anchors, http: //www.stroitmeh. Ru / lect24.htm). In such a system, it is almost impossible to ensure uniform loading of the support elements. In the case of the massager, it is impossible to ensure a uniform distribution of the pressing force of the massager between the massage heads, resulting in a physiotherapeutic the effect of the massager on the user's body is uneven. In addition, the fixed fixing of the massage heads prevents the adaptation (adaptation) of the massage heads to the curvature of the user's body. These circumstances reduce the effectiveness of the massage procedure.

The basis of the invention is the task of ensuring a uniform distribution of the pressing force of the massager between the massage heads and improving the adaptive properties of the massager to the curvature of the user's body, which increases the effectiveness of the massager.

The problem is solved in that in the massager containing the body, several massage nodes with massage heads mounted on the body with the possibility of influencing the user's body, according to the invention, each of the massage nodes is fixed to the body with a ball joint and contains several interconnected massage heads, three of which are located in the same plane with the possibility of simultaneous impact on the user's body.

These signs are essential features of the invention, as they are necessary and sufficient to achieve a technical result — uniform distribution of the pressure of the massager against the massage heads and improvement of the adaptive properties of the massager to the curvature of the user's body.

Unlike the prototype, in the proposed solution, the massage nodes are connected to the body by ball joints and contain several connected massage heads, three of which are located in the same plane with the possibility of simultaneous impact on the user's body. That is, such a massage unit always contacts the user's body (rests on the user's body) with three massage heads. In this embodiment, each massage unit is a three-leg statically defined structure in which the supporting elements (massage heads) are loaded uniformly. The connection of the massage units with the body using ball joints provides the massage units with the ability to adapt (adapt) to the curvature of the user's body by turning in ball joints

Massage heads can be located at the vertices of the tetrahedron, whose faces are tangent to the massage heads and interconnected by rods intersecting in the center of the tetrahedron to form a ball head at the intersection. Massage heads can be located in the corners of the base of the trihedral pyramid and interconnected by rods intersecting at the top of the pyramid with the formation of a ball head at the intersection.

Massage heads can be made on at least one side of the plate, on the opposite side of which a ball head is fixed, while the number of massage heads is three.

Each ball joint can be made in the form of a spherical recess in the holder, in which the ball head located on the massage unit is located.

Each ball joint can be made in the form of a spherical recess in the holder, in which one of the massage heads of the massage unit is located as a ball head.

The number of massage nodes is advisable to choose three, while the massage nodes are located on the peripheral sections of the holder along the circumference in increments of 120 degrees. This design is statically defined with a uniform distribution of the pressure of the massager between the massage heads.

To enhance the reflex effect of the massager, at least one of the massage heads can be made with at least one radial protrusion.

It is advisable to arrange the radial protrusions along the line of intersection of the solid angle equal to 2 <p degrees with the surface of the massage head, where f is the angle of inclination of the shaft on which the massage head is fixed to the central axis of the massage unit. With this embodiment, the radial protrusions will be located in the corresponding planes (faces of the tetrahedron or pyramid) and protrude in the perpendicular direction relative to the planes in which they are located.

Radial protrusions can be made either cylindrical, or conical, or other spatial configuration.

Radial protrusions can be made of the material of the massage head in one piece with the massage head.

At least one of the radial protrusions can be made in the form of an insert fixed in the body of the massage head.

The insert may be made of metal.

The metal insert can be made at least with a single layer partial coating, while the coating materials and inserts are selected with different electrochemical potentials. In this case, galvanic pairs that, when in contact with the skin of the user, provide the known effects of galvanizing the skin and electrophoresis.

The insert can be made of magnetic material, which provides exposure to the user's body with a constant magnetic field.

The insert can be made of natural mineral, which allows you to use the healing properties of natural minerals.

Massage it is advisable to fix on the rods with the ability to reinstall in different positions around the axes of the rods and fixation in the selected position.

The massager contains a holder 1 with a handle 2 on the upper side of the holder 1. The holder 1 is made with three brackets 3 located at an angle of 120 degrees with respect to each other. Each bracket 3 is made with a longitudinal slot 4 and a spherical recess 5 on the lower side of the bracket 3. On the peripheral sections of the brackets 3 are mounted in one horizontal plane three massage nodes (Fig. 1-3).

Each massage unit contains four massage heads 6 located at the vertices 7 of the tetrahedron and interconnected by rods 8, 9, 10, 11 intersecting in the center 12 of the tetrahedron. At the intersection of the rods 8, 9, 10, 11, a ball head 13 is made with a spherical surface 14 (Fig. 4-6). Each of the faces of the tetrahedron is tangent to three corresponding massage heads 6. Each of the faces of the tetrahedron can be used as a working one, which makes it possible to affect the user's body with one or another three massage heads 6, depending on which of the faces of the tetrahedron is used as working.

Massage units are fixed on the brackets 3 with the help of ball joints formed by spherical recesses 5 made in brackets 3, in which are located, as ball heads 13 with a spherical surface 14, made at the intersection of the rods 8, 9, 10, 11. Thus , massage nodes in contact with the user's body can freely rotate in ball joints in any direction and occupy a position in which the massage heads are evenly pressed against the body part, regardless of the geometry of the site (convex or concave surface of the body). That is, in this embodiment, the massage unit automatically adapts to curved sections of the body, providing a uniform effect of the massage heads on the user's body.

In FIG. 7-9 show various positions of the massage unit in the longitudinal plane of the bracket 3. In FIG. 10-12 - in the transverse plane of the bracket 3.

To enhance the physiotherapeutic effect, at least one of the massage heads 6 can be made with at least one radial protrusion. In FIG. 13, 14 shows an example of a massage head 6 with three radial protrusions 15, 16, 17. Radial protrusions are located along the line of intersection of the solid angle of 2 cp degrees with the surface of the massage head in increments of 120 degrees, where f is the angle of inclination of the rod on which the massage head is fixed to the central axis of the tetrahedron.

Radial protrusions can be either conical (15), or cylindrical (16), or of a complex configuration, for example, a raspberry-like type (17). This embodiment ensures the location of one of the protrusions 15, 16, 17 on one of the faces of the tetrahedron and its protrusion in the direction perpendicular to the plane of the face. Choosing one of the faces of the tetrahedron as the working one, the nature of the massage effect on the user's body is chosen: either with the spherical surface of the massage head 6 (Fig. 15), or with raspberries of the "raspberry" type 17 (Fig. 16), or cylindrical protrusions 16 (Fig. 17 ), or conical protrusions 15 (Fig. 18), or a combination of protrusions 15, 16, 17. The choice of the working face of the tetrahedron is made by reinstalling the massage unit in the ball joint, bearing in mind that the lower face of the tetrahedron will always be the working face.

The radial protrusions can be made of the material of the massage head 6 in one piece with the massage head 6 (Fig. 19, position 18) or in the form of an insert fixed in the body of the massage head 6. In FIG. 19 shows an insert 19 made of metal. On 20 - a metal insert 20 with a partial coating 21, the electrochemical potential of which differs from the electrochemical potential of the material of the insert; in this case, a galvanic pair “metal insert 20 - coating 21” is formed, which when in contact with the user's body generates galvanic microcurrents 1e, which provide the known effects of galvanizing the skin and electrophoresis. As materials for the insert 20 can be used, for example, steel, copper, chromium, nickel, aluminum, zinc, titanium, as well as their alloys and oxides. Coating materials 21 can be, for example, copper, chromium, nickel, aluminum, zinc, titanium, as well as tin, silver, gold, platinum and other materials with various electrochemical potentials. In Fig. 21, an insert 22 made of magnetic material provides an impact on the user's body with a constant magnetic field. In FIG. 22 - insert 23 made of natural mineral, which allows you to use the healing properties of natural minerals.

In FIG. 23-25 shows a diagram (sequence of operations) of the massager assembly with integral massage heads 6. FIG. 23 - initial position, FIG. 24 is an intermediate position, FIG. 25 - position in the assembled state. The ball head 13 of the massage unit is led into a spherical recess 5 through the longitudinal slot 4 of the bracket 3, pushing the free ends of the bracket 3 within the elastic properties. After placing the ball head 13 of the massage unit in spherical recess 5, the free ends of the bracket 3 are returned to their original position, fixing the massage unit in the working position.

In FIG. 26-28 shows a diagram (sequence of operations) of the massager assembly with detachable massage heads 24. FIG. 26 - initial position, FIG. 27 is an intermediate position, FIG. 28 - position in the assembled state. To assemble the massager, one of the massage heads 24 is removed (unscrewed) (depending on which face of the tetrahedron is chosen as the working one). The ball head 13 of the massage unit is installed in a spherical recess 5. The previously removed massage head 24 is screwed in place - the massage unit is in working position.

The ball joint can be made in the form of a spherical recess in the holder, in which one of the massage heads of the massage unit is located as a ball head.

On Fig shows an example of a massager with the specified implementation of the ball joint. The massager contains a disk-shaped holder 25 with a handle 26 on the upper side. On the bottom side of the holder 25, spherical recesses 27 are made, which are located on the peripheral portion of the holder 25 along the circumference in increments of 120 °. The massager also contains a locking disk 28, in which spherical recesses 29 are made, which are located in accordance with the location of the spherical recesses 27 in the holder 25. One of the massage heads 6 is located in these spherical recesses 27, 29. Thus, the spherical recesses 27 in the holder 25, the spherical recess 29 in the locking disk 28, as well as one of the massage heads 6 of the massage unit form a ball joint of the massage unit with the holder 25 of the massager. In the locking disk 28 in the places where the recesses 29 are made, radial grooves 30 are made, which allow the installation of massage heads 6 in the recesses 29 when assembling the massager (or removing the massage heads 6 from the recesses 29 when disassembling the massager).

The locking disk 28 is mounted on the back side of the massager holder 25 with a detachable screw connection that includes a screw 31 installed in the through hole 32 made in the holder 25 and in the handle 26. The hole 32 is made with a bottom 33. The threaded section 34 of the screw 31 is installed in a threaded hole 35 made in the central part of the locking disk 28. The screw detachable connection of the locking disk 28 with the massager holder 25 is spring-loaded towards pressing the locking disk 28 against the holder 25. To do this, in the hole 32 on terzhne screw 31 is installed a helical spring 36, one end of which rests on the bottom of a hole 33, 32, and the other - to the head 37 of the screw 31, providing the necessary pressing of the locking disk 28 to the lower part of the holder 25. In this design, the simple technical means make it possible to replace the massage units, the ability to replace the massage heads 6 in the ball joints, as well as the ability to control the clamping force of the massage heads 6 in the ball joints.

When performing the massage head 6 with radial protrusions, the ball joint is performed with a detachable spherical liner 38 covering the radial protrusions of the massage head b, which is the ball head of the joint (Figs. 30, 31). This makes it possible to install a massage head 6 with radial protrusions in a ball joint and favorable operating conditions of the ball joint.

The massage unit may be arranged with the massage heads 39 at the corners of the base 40 of the trihedral pyramid 41, which are interconnected by rods 42 intersecting at the top of the pyramid 41 to form a ball head 43 at the intersection (Figs. 32-34).

The massage unit may be made with massage heads 44 fixed on one side of the plate 45, on the opposite side of which the ball head 46 is fixed (Figs. 35-37).

The massage unit can be made with massage heads 47 on one side of the plate 45 and massage heads 48 on the opposite side of the plate 45. In the center of the plate 45 between the massage heads 47, 48, the ball head 49 is fixed using a screw 50 with the possibility of its installation on one side plates 45 (Figs. 38-42). The massage heads 47 are conical, the massage heads 49 with a spherical surface, which allows you to change the mechanical effect of the massage heads on the user's body, choosing one of the sides of the plate 45 as the working side (Fig. 41, 42).

Massage heads can be fixed on the rods with the possibility of reinstallation in various positions relative to the axes of the rods and fixation in the selected position. In FIG. 43-46 shows an example of the specified implementation. The rod 42 is made with a shank 51 of a prismatic shape, for example, with a square (Fig. 44) or triangular (Fig. 45) cross-section. The massage head 39 is made with a radial hole 52, the cross section of which corresponds to the cross-sectional shape of the shank 51. The shank 51 is placed in the radial hole 52. The massage head 39 is fixed to the shank 51 with a screw 53. The massage head 39 is made with radial protrusions 54, 55, 56, 57 of various shapes, which are located opposite the corresponding faces of the shank 51 (Fig. 44, 45). Reinstalling the massage head 39 on the shank 51, choose one of the radial protrusions 54, 55, 56, 57, which will affect the body of the user. In FIG. 47-50 show the positions of the head 39, in which it acts on the user's body with different radial protrusions 54, 55, 56, 57 (Fig. 47 - conical protrusion 54 with a pointed apex, Fig. 48 - conical protrusion 55 with a blunt apex, fig. 49 - protrusion 56 with a spherical surface, Fig. 50 - protrusion 57 with a complex surface configuration of the type "raspberry"). The ability to install the heads 39 in various positions determines the variety of mechanical effects of the massager on the user's body.

Before the massage, massage nodes with protrusions or inserts on the massage heads are pre-selected, depending on the purpose of the massage procedure. Install massage units in ball joints. During the massage, the massager using the handle is pressed with the necessary force to the surface of the corresponding part of the body and the massager is moved in various directions. In this case, the massage nodes contact their massage heads with the massaged body area at nine points (nine massage heads).

In FIG. 51, 52 shows a diagram of the distribution of the massager’s efforts, where Pi is the pressing force of the massager, P2 is the force transmitted to the massage nodes, and Pz is the force by which the massage heads 39 act on the user's body. Moreover, P2 = 1 / ЗР1, Рз = 1/9 Р1. The pressing force of the massager P1 is evenly distributed between the massage heads 39 (force Pz).

On Fig, 54 shows an example of a similar massager, made with a more "tight" arrangement of the massage heads 39.

The masseur described above can be aggregated into more complex massage designs. In FIG. 55, 56 shows a diagram of a massager with the three massagers described above, the holders 1 of which are connected to the holder 58 by ball joints 59. Ball joints 59 are located on the peripheral portions of the holder 58 along a circle in increments of 120 °. In this case, the massage nodes contact their massage heads 39 with the user's body at twenty-seven points (twenty-seven massage heads 39).

In FIG. 56 shows a diagram of the distribution of the massager’s efforts, where Pi is the pressing force of the massager, P2 is the force transmitted to the holders 1 of the massagers described above, P3 is the force transmitted to the massage nodes, P4 is the force by which the massage heads 39 act on the user's body. Moreover, P2 = 1 / ЗР1, Рз = 1/9 Pi, Р4 = 1 / 27Р1. The pressing force of the massager P1 is evenly distributed between the massage heads 39 (effort P4). The impact forces at all points of contact of the massage heads with the massaged area will be equal, including the curved parts of the body, due to the design features of the massager. In FIG. 57 shows a diagram of the interaction (adaptation) of massage nodes with a convex portion of the user's body, FIG. 58 - with a concave portion of the user's body.
