Description

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 invention No. 2220698, IPC А61Н 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 selected 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 features 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 chosen as a prototype (patent of the Russian Federation for invention No. 2270659, IPC А61Н 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, which is 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 nodes 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 prototype and the claimed solution are: a massager containing a holder, massage units with massage heads mounted on the holder 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 units with massage heads on the body of the massager that contact the surface of the massaged body area (with which the massager rests on the body surface) when performing massage procedures. It is well known that a mechanical system made with more than three supporting elements is a statically indeterminate system (statically indeterminate is a system 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, as a result of which the physiotherapeutic 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, improving the adaptive properties of the massager to the curvature of the user's body, increasing the efficiency of the massager.

The problem is solved in that in the massager containing the holder, massage nodes with massage heads mounted on the holder with the possibility of impact on the user's body, according to the invention, the massager contains three massage nodes, each of which is mounted on the holder using a ball joint and is made in in the form of massage heads located at the vertices of the tetrahedron and interconnected by rods intersecting in the center of the tetrahedron with the formation of a spherical ball head at the intersection of the rods, each massage head made with four radial protrusions located uniformly along the intersection line of the solid angle equal to 2ϕ degrees, with the surface of the massage head, where ϕ is the angle of inclination of the rod on which the massage head is fixed to the central axis of the massage unit.

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

In contrast to the prototype, the claimed massager contains three massage units connected to the holder with ball joints and made in the form of massage heads located at the vertices of the tetrahedron, interconnected by rods intersecting in the center of the tetrahedron to form a ball joint at the intersection of the ball head. That is, each massage unit contains four possible working planes (four faces of the tetrahedron), in each of which there are three massage heads. In this embodiment, the user’s body is affected by three articulated massage nodes, each of which acts on the user’s body with three massage heads located in the plane of the octahedron face selected as the working face. Each massage unit in any case, regardless of the choice of the faces of the octahedron as the working one, contacts only three massage heads with the user's body (rests on the user's body). In this embodiment, each massage unit is a three-leg statically defined structure in which support elements (massage heads) are loaded uniformly. The connection of massage nodes with the body using ball joints provides the massage nodes with the ability to adapt (adapt) to the curvature of the user's body by turning in ball joints. The arrangement of four (in terms of the number of faces of the tetrahedron) radial protrusions uniformly along the line of intersection of the solid angle equal to 2ϕ degrees with the surface of the massage head, where ϕ is the angle of inclination of the rod on which the massage head is attached to the central axis of the massage unit, provides the location of the radial protrusions in corresponding planes (faces of the tetrahedron) and their protrusion in the perpendicular direction relative to the planes (faces of the tetrahedron) in which they are located.

Each ball joint can be made in the form of a spherical recess in the holder, in which the ball head of 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.

It is advisable to arrange the massage nodes in the peripheral parts 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.

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

Radial protrusions can be made in the form of inserts fixed in the body of the massage head.

The inserts can be made of metal.

Metal inserts can be made with at least a single-layer partial coating, while the coating materials and inserts are selected with different electrochemical potentials. In this case, galvanic couples are formed, which upon contact with the user's skin provide the known effects of galvanizing the skin and electrophoresis.

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

The inserts 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 to 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 to the body part, regardless of the geometry of the site (convex or concave body surface). 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 the various positions of the massage unit in the longitudinal plane of the bracket 3. 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 performed 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 equal to 2ϕ degrees, with the surface of the massage head in increments of 120 degrees, where ϕ is the angle of inclination of the rod, which is fixed massage head 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 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 a working one, the nature of the massage effect on the user's body is selected: 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 lg, which provide the known effects of galvanizing the skin and galvanic electrophoresis. As materials for insert 20, for example, steel, copper, chromium, nickel, aluminum, zinc, titanium, as well as their alloys and oxides, can be used. 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 the spherical recess 5, the free ends of the bracket 3 return 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, which is located, as a ball head, one of the massage heads of the massage unit.

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, located in accordance with the location of the spherical recesses 27 in the holder 25. One of the massage heads 6 is located in the specified 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 that 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, which 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. For this, a coil spring 36 is installed in the hole 32 on the screw shaft 31, one end which rests on the bottom 33 of the hole 32, and the other on the head 37 of the screw 31, providing the necessary pressing of the locking disk 28 to the bottom of the holder 25. In this design, simple technical means make it possible to replace the massage units, the ability to replace the massage heads 6 in ball joints, as well as the ability to control the clamping force x 6 heads in ball joints.

When performing the massage head 6 with radial protrusions, the ball joint is made with a detachable spherical liner 38 covering the radial protrusions of the massage head 6, 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 for the ball joint.

The massage unit may be arranged with the massage heads 39 at the corners of the base 40 of the triangular 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 made 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). By reinstalling the massage head 39 on the shank 51, one of the radial protrusions 54, 55, 56, 57, which will affect the user's body, is selected. 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 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 P ₁ is the pressing force of the massager, P ₂ is the force transmitted to the massage nodes, P ₃ is the force by which the massage heads 39 act on the user's body. Moreover, P ₂ = 1 / 3P1, P ₃ = 1/9 P ₁ . The pressing force of the massager P _{1 is} evenly distributed between the massage heads 39 (effort P ₃ ).

On Fig 53, 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. The 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 P ₁ is the pressing force of the massager, P ₂ is the force transmitted to the holders 1 of the above massagers, P ₃ is the force transmitted to the massage nodes, P ₄ is the force by which the massage heads 39 act body of the user. Moreover, P ₂ = 1 / 3P ₁ , P ₃ = 1/9 P ₁ , P ₄ = 1 / 27P ₁ . The pressing force of the massager P _{1 is} evenly distributed between the massage heads 39 (effort P ₄ ).

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 body of the user, in FIG. 58 - with a concave portion of the user's body.
