Description

Technical Field

[0001] The present invention belongs to the technical field of massage, and relates to a technique for enhancing massage effects and rehabilitation effects. Specifically, it relates to a massage module and an in-body massage device equipped with the same.

Background Art

[0002] Women often have many sequelae after childbirth. A common sequela is pelvic floor muscle relaxation. Pregnancy and childbirth are known to cause relaxation of a woman's pelvic floor muscles, leading to symptoms such as vaginal wall prolapse, urinary incontinence, and pelvic organ prolapse. Therefore, women should promptly recover and treat their pelvic floor muscles after childbirth. Currently, there are mainly two types of commonly used postpartum rehabilitation devices.

[0003] The first type achieves the purpose of stimulating the vaginal muscles by vibrating an in-body insulating rod.

[0004] The second type is a vaginal mucosa repair model. Specifically, by contracting and expanding a massage ball through pneumatic pressurization, the massage and stimulation effects of an in-body massage element are realized. However, the massage stimulation points formed by such a massage ball are relatively fixed and concentrated, and there is a drawback of reducing its massage effect.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention provides a massage module and an in-body massage device that can solve the problems described in the above prior art.

Means for Solving the Problems

Embodiments for Carrying out the Invention

[0009] Hereinafter, with reference to the drawings of the embodiments of the present invention, the technical proposals according to the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present invention.

[0010] Hereinafter, with reference to FIGS. 1 to 7, specific embodiments of the massage module and the in-body massage device of the present invention will be described in detail.

[0011] [First Embodiment] As shown in FIG. 1 and FIGS. 2a to 2c, the massage module provided by the first embodiment of the present invention includes a main body part 1 and a massage element 3. The main body part 1 can be entirely inserted into the hole-shaped massage target part 2. The main body part 1 has a columnar body 10 and a recess 5 provided in the columnar body 10. One end of the main body part 1 where the recess 5 is provided forms an approximately arc and rises upward. The recess 5 is formed by the outer wall on one side of the main body part 1 being recessed inward. The massage element 3 is provided in the recess 5. In this embodiment, since the recess 5 is provided only on one side of the main body part 1, the main body part 1 has only one opening 103.

[0012] The columnar body 10 has a structure that matches the inner cavity of the hole-shaped massage target part 2. Specifically, the part where the columnar body 10 is located has a substantially cylindrical structure that fits into the inner cavity of the hole-shaped massage target part 2, such as a cylindrical shape, a quasi-cylindrical shape, or a prismatic shape with rounded corners. The columnar body 10 is entirely inserted into the hole-shaped massage target part 2, and at the same time, it is inserted into the hole-shaped massage target part 2 together with the recess 5. Here, the columnar body 10 has a front stage, a middle stage, and a rear stage. The recess 5 can be arranged in any segment. Preferably, by arranging the recess 5 at a position close to the rear stage of the columnar body 10, another massage module can be arranged inside the front stage. For example, an electric telescopic structure or an electric vibration structure may be provided at the front stage of the columnar body 10.

[0013] The massage element 3 includes a lever part 31 and at least one massage protrusion 33 (also called a massage head) located at the tip of the lever part 31. The lever part 31 protrudes outward from the opening 103, serves to support the massage protrusion 33, and moves the massage protrusion 33 to swing within the recess 5. The massage protrusion 33 has a massage surface 301 that can act at least on the inner cavity of the hole-shaped massage target part 2 (the circumferential wall surface thereof constitutes the massage surface). When the massage element 3 is operating, the massage surface 301 acts on the inner cavity of the hole-shaped massage target part 2. Also, the massage protrusion 33 of the present invention can provide a tactile pressure effect in a dot-like area and can bring a higher sense of stimulation compared to a large-area massage.

[0014] The massage surface 301 is a curved surface and acts directly or indirectly on the hole-shaped massage target part 2. When the massage protrusion 33 is in direct contact with the inner wall surface of the hole-shaped massage target part 2, the circumferential wall surface of the massage protrusion 33 massages and stimulates the hole-shaped massage target part 2 as a massage surface. Specifically, the massage protrusion 33 can be hard, soft, or in a form where the soft part wraps the hard part. According to different needs, the material of the massage protrusion 33 can be selected. In this form, since there is no isolation between the massage protrusion 33 and the hole-shaped massage target part 2, the skin or tissue of the hole-shaped massage target part 2 can be wrapped or locally wrapped by the massage protrusion 33. When performing the massage operation, the massage area directly formed by the massage protrusion 33 is larger, the sense of stimulation felt by the human body is stronger, and it is helpful for the recovery of the hole-shaped massage target part 2. Also, the massage surface and the hole-shaped massage target part 2 move relative to each other. That is, during the movement of the massage protrusion 33, the circumferential wall surface thereof and the inner wall surface of the hole-shaped massage target part slide relatively to cause friction, achieving the effects of massage and stimulation.

[0015] Alternatively, the massage protrusion 33 may indirectly contact the inner wall surface of the hole-shaped massage target part 2. That is, the massage protrusion 33 can be covered with the flexible layer 101. This flexible layer 101 may be a flexible layer wrapped around the entire circumferential wall surface of the main body part 1, or a flexible layer covering the recess 5. Here, the flexible layer 101 forms an action region 1011. The massage protrusion 33 deforms the action region 1011 of the flexible layer 101 within the recess 5. When the massage protrusion 33 performs a massage operation, by moving and deforming the wall surface of the flexible layer 101, the effects of massage and stimulation are formed. Here, in the initial state, the massage protrusion 33 partially shows traces, for example, forms minute ridges or protrusions on the flexible layer 101. In this case, the flexible layer 101 applies a certain flexible restraint force to the massage protrusion 33, and the width of the massage operation can be relaxed to a certain extent. When the massage protrusion 33 performs a massage operation, its traces become more prominent. That is, the amount of strain generated in the flexible layer 101 gradually increases to perform the function of massage stimulation.

[0016] In this form, there is no relative sliding between the massage surface and the hole-shaped massage target part 2, and only the massage protrusion 33 moves and deforms the flexible layer to realize the effects of massage and stimulation. Therefore, relatively relaxed massage and stimulation are achieved, and secondary injury to the wound is prevented.

[0017] When the degree of injury is high, the massage protrusions 33 can be covered by the flexible layer 101 to adopt a state where the traces are either visible or do not appear completely. The massage and stimulation effects in these two states are more relaxed and less likely to cause secondary injury to the wound. Also, the massage operation of the massage protrusions 33 is restricted by the flexible layer 101, and it is possible to avoid secondary tearing of the wound due to the massage width being too large. When the degree of injury is low, a state where all the massage protrusions 33 appear can be adopted. In this state, the massage effect is better, and the massage protrusions 33 are not restricted, and their operating width is relatively large, and a large stimulation can be formed.

[0018] Also, the massage protrusions 33 exhibit at least a visible state, a locally visible state, or an invisible state in the non-operating state. Here, the aforementioned visible state is a state where all the massage protrusions 33 are exposed. Under the visible viewing angle, the massage protrusions 33 and the main body 1 or the recess 5 are clearly independent of each other, and there is no shielding object around them. The aforementioned locally visible state is a state where the massage protrusions 33 are covered by the flexible layer 101 and a part of the trace appears. The aforementioned invisible state is a state where the massage protrusions 33 are completely covered by the flexible layer 101 and cannot be seen.

[0019] Preferably, the maximum radius of curvature R of the curved surface of the massage surface 301 is 5 to 10 mm. The range of the swing angle φ when the massage protrusion 33 performs a swinging motion is 30° to 60°. By limiting the radius of curvature of the massage protrusion 33 within this range, it is possible to prevent the blocking feeling of the massage operation due to the force-receiving area being too large, and to prevent the improvement of massage pain and the reduction of comfort due to the force-receiving area being too small. On the other hand, by optimizing the swing angle of the massage protrusion 33, it is possible to prevent the reduction of the concentrated feeling and strong feeling of the massage due to the swing angle being too large, and to prevent the reduction of the massage area due to the swing angle being too small. The recess 5 is formed by recessing inward from one side wall or both opposite side walls of the columnar body 10, and an opening 103 is formed on at least one side of the columnar body 10. Preferably, the recess 5 is integrally formed on the main body 1 without changing the original radial dimension of the main body 1.

[0020] The massage protrusion 33 is provided inside the recess 5 and protrudes from the outer peripheral surface of the columnar body 10 via the opening 103. The massage protrusion 33 has an appropriate degree of freedom in the recess 5. The aforementioned degree of freedom enables the massage protrusion 33 to perform a smooth and moderately force-controlled massage operation. In this embodiment, the aforementioned massage operation is an opposing swinging motion or a lifting motion along the vertical direction.

[0021] In this embodiment, the massage element 3 can be driven in two driving methods. That is, there are two motion methods for the massage element 3.

[0022] The first type is a rocking motion. The massage element 3 has a certain degree of freedom within the recess 5. The aforementioned degree of freedom enables the massage element 3 to perform a rocking motion facing along the longitudinal direction of the recess 5. Specifically, a clamping - type massage effect is obtained by rocking such that the heads of the two massage protrusions 33 face each other and approach or move away from each other. When a plurality of massage protrusions 33 rock, the massage area formed by each massage protrusion 33 is the same as or similar to the somatic sensation stimulation received when using a single massage protrusion 33. The difference is that a third massage area is further formed between adjacent massage protrusions 33. The massage object located within this third massage area receives the kneading action from two adjacent massage protrusions 33, and the sense of stimulation is further increased.

[0023] In this rocking mode, as shown in FIG. 6a, the rocking drive assembly 40 includes a rocking motor 41 and a rocking arm 43 connected to the rocking motor 41. The rocking arm 43 is further connected to the massage protrusion 33. Here, the rocking arm 43 is hingedly connected inside the main body 1. In this embodiment, by rocking the rocking arm 43 via the rocking motor 41, the massage protrusion 33 is driven to perform a rocking motion (the opposing rocking is namely a pinching operation). Since the rocking mechanism of the prior art is relatively mature, it will not be described in detail here.

[0024] The second type is a lifting motion. Specifically, the massage protrusion 33 continuously applies a biasing force along the width direction of the main body 1 to the hole - shaped massage target part 2, giving a stronger sense of stimulation.

[0025] In this movement mode, a lifting drive assembly (not shown) is provided inside the main body 1. This lifting drive assembly includes a lifting motor, a cam connected to the lifting motor, and a lifting arm that abuts against the cam. The lifting arm is connected to the massage protrusion. By rotating the cam with the lifting motor and further intermittently raising the lifting arm, the lifting process of the massage protrusion 33 is realized. In the prior art, since there are many mechanisms for realizing the lifting process, no further explanation will be given here.

[0026] When the massage protrusion 33 performs a massage operation, since the recess 5 is recessed by a certain depth M along the short side direction of the main body 1, a certain operating space is provided for the massage protrusion 33. The increase in the operating space means that the massage protrusion 33 has a higher degree of freedom. When the massage protrusion 33 performs massage stimulation within the recess 5, there are the following advantages.

[0027] First, the partial structure of the massage protrusion 33 (the partial rod or all rods of the massage protrusion 33) is hidden within the recess 5. When the length of the massage protrusion 33 is constant, comparing the massage protrusion 33 mounted within the recess 5 (hereinafter referred to as the former) with the massage protrusion 33 mounted on the circumferential wall surface of the main body 1 (hereinafter referred to as the latter), the former has a smaller degree of lifting the female's hole-shaped massage target site 2. That is, the amount of distortion when the hole-shaped massage target site 2 is forcibly deformed is smaller. This means that during the stage when the main body 1 enters the hole-shaped massage target site 2 and the subsequent massage stage, the damage to the hole-shaped massage target site 2 is smaller, avoiding secondary damage to the hole-shaped massage target site 2. However, the latter has a greater degree of lifting the female's hole-shaped massage target site 2. That is, in the case of the latter, during the entry stage and the massage stage of the main body 1, the inner wall of the hole-shaped massage target site 2 is easily damaged, which is disadvantageous for the postpartum recovery of women.

[0028] Second, when the degree of lifting of the massage protrusion 33 with respect to the concave massage target part 2 of the female is constant, the massage protrusion 33 (hereinafter, the former) mounted in the recess 5 can have its length adjusted to be longer than that of the massage protrusion 33 (hereinafter, the latter) mounted on the circumferential wall surface of the main body part 1. When the massage protrusion 33 performs a massage operation, especially when performing a swinging massage operation, massage operations in multiple directions can be realized, the formed massage area is larger, and the massage effect and the sense of stimulation can be enhanced. On the other hand, since the length of the latter is relatively short, when performing a massage operation, especially during a swinging operation, the formed massage area becomes smaller, and its massage effect is weakened.

[0029] [Second Embodiment] Hereinafter, with reference to FIGS. 3a and 3b, the aspect of the second embodiment of the present invention will be described. In the following description, elements having the same configuration and function as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0030] The massage module 100a according to this embodiment includes a main body part 1a, two recesses 5a formed by recessing inward from both opposite side walls of the main body part 1a, and a massage element 3a provided in the recesses 5a. In this embodiment, the two recesses 5a are provided so as to penetrate each other, and one opening 103a is formed on each side of the main body part 1a. In this embodiment, the massage element 3a includes two massage columns 30a protruding outward from the openings 103a on both sides of the main body part 1a. Both ends of each massage column 30a have small spherical massage protrusions 33a respectively. That is, the massage element 3a includes four small spherical massage protrusions 33a disposed on both opposite sides of the main body part 1a.

[0031] In this embodiment, the two massage columns 30a reciprocally slide so as to approach each other (see FIGS. 3a and 3b) or move away from each other along the longitudinal direction of the recess 5a. In this process, the massage projections 33a at both ends thereof bring about a sliding massage or a stimulating effect on the wall surface of the human body channel. Similarly, the massage projections 33a located on both sides of the main body 1a may be covered by the flexible layer 101. The flexible layer 101 may be a flexible layer that wraps around the entire circumferential wall surface of the main body 1, or a flexible layer that covers the opening 103a of the recess 5a. Here, the flexible layer 101 forms an action region 1011. The massage projection 33a deforms the action region 1011 of the flexible layer 101 within the recess 5a. When the massage projection 33a performs a massage operation, by moving and deforming the wall surface of the flexible layer 101, a massage or stimulating effect is formed.

[0032] In this two-way sliding motion mode, as shown in FIG. 6b, a slide drive assembly 50 is provided within the main body 1a. The slide drive assembly 50 includes a telescopic motor 51, a transmission rod 53 connected to the telescopic motor 51, and a screw sleeve 55 screwed onto the transmission rod 53. The two massage columns 30a are connected to the screw sleeve 55 (a through groove is opened on the bottom surface of the recess 5a to connect the two). In this embodiment, the transmission rod 53 is moved and rotated via the telescopic motor 51. More specifically, the screw sleeve 55 includes a first screw sleeve and a second screw sleeve, and the spiral directions of the screw grooves (not shown) formed on the outer surfaces of the first screw sleeve and the second screw sleeve are opposite. The first screw sleeve passes through one massage column 30a, and the second screw sleeve passes through the other massage column 30a. The telescopic motor 51 can rotate intermittently clockwise or counterclockwise, and at the same time, synchronously rotate the transmission rod 53.

[0033] When the telescopic motor 51 rotates clockwise, the two massage columns 30a respectively mounted on the first screw sleeve and the second screw sleeve move in a direction approaching each other. When the telescopic motor 51 rotates counterclockwise, the two massage columns 30a respectively mounted on the first screw sleeve and the second screw sleeve move in a direction away from each other. Thereby, the massage device adopting the massage module 100a according to the present embodiment can bring a better massage effect to the user.

[0034] [Third Embodiment] Hereinafter, with reference to FIGS. 4a and 4b, the aspect of the third embodiment of the present utility model will be described. In the following description, elements having the same configuration and function as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0035] The massage module 100b according to the third embodiment of the present invention includes a main body portion 1b, two recesses 5b formed by being recessed inward from opposite side walls of the main body portion 1b, and a massage element 3b provided in the recesses 5b. In this embodiment, the two recesses 5b are provided so as to penetrate each other and form one opening 103b on each side of the main body portion 1b, and the massage element 3b includes only one massage column 30b. Both ends of the massage column 30b protrude outward from the openings 103b on both sides of the main body portion 1b, and small spherical massage protrusions 33b are formed at the ends thereof. Similarly, in this embodiment, the massage protrusions 33b located on both sides of the main body portion 1b may be covered with the flexible layer 101. This flexible layer 101 may be a flexible layer wrapped around the entire circumferential wall surface of the main body portion 1, or a flexible layer covering the opening 103b of the recess 5b. Here, the flexible layer 101 forms an action region 1011. The massage protrusion 33b deforms the action region 1011 of the flexible layer 101 within the recess 5b. When the massage protrusion 33b performs a massage operation, the wall surface of the flexible layer 101 is moved and deformed to form the effect of massage or stimulation.

[0036] In this embodiment, the massage post 30b reciprocates linearly along the longitudinal direction of the main body 1b within two recesses 5b that penetrate each other. In this process, the massage protrusions 33b at both ends thereof bring about a sliding type massage or stimulation effect on the wall surface of the human channel.

[0037] In this unidirectional slide movement mode, a slide drive assembly 50 similar to the slide drive assembly described in the second embodiment is provided inside the main body 1b. Compared with the second embodiment, the only difference is that the spiral directions of the screw grooves (not shown) formed on the outer surface of the transmission rod 53 are the same.

[0038] In this embodiment, one massage post 30b is connected to the screw sleeve 55. The transmission rod 53 is rotated via the telescopic motor 51, and further, the massage protrusion 33 is reciprocated linearly by the screw sleeve 55. Of course, this structure is exemplary. There are many reciprocating linear motion mechanisms in the prior art. The present invention may adopt the drive mechanisms described in the prior art, and detailed description is omitted here.

[0039] In the movement processes of the above first to third embodiments, various operation modes of the massage protrusions 33, 33a, and 33b are provided. However, no matter which operation mode is selected, the recesses 5, 5a, and 5b can all provide appropriate degrees of freedom for the massage protrusions 33, 33a, and 33b, reduce the restraint force on the massage protrusions 33, 33a, and 33b, and enable the massage operation to be performed better.

[0040] It should be noted that in the above first to third embodiments, the massage protrusion 33 can be formed as a small sphere, hemisphere, rounded block, column, tongue-like body, etc., as long as it does not damage the user's channel during the massage process.

[0041] For better understanding, the recesses 5, 5a and 5b may have regular shapes such as rectangles, circles or ellipses, or irregular shapes. Here, it is not specifically restricted. As long as the structure has recesses opened on the circumferential wall surfaces of the main body parts 1, 1a and 1b, all are included within the protection scope of this application.

[0042] Also, as described in the first embodiment, the massage columns 30a, 30b of the massage modules 100a, 100b according to the second and third embodiments can realize reciprocating linear motion along the width direction of the recesses 5a, 5b by means of a lifting motor and a lifting arm, so as to alternately apply a dot-like tactile massage effect to the inner cavity walls of the hole-shaped massage target parts 2 on both sides.

[0043] Also, the dimensions of the recesses determine to a certain extent the area of the operating region of the massage protrusions. Although the area of the operating region shows a positive correlation with the stimulation to the body feeling, the following two points need to be considered.

[0044] First, as the area of the operating region increases, the massage region formed by the massage protrusions increases synchronously. As a result, the risk of the massage protrusions contacting the wound increases.

[0045] Second, although the recesses increase the degree of freedom of movement of the massage protrusions to a certain extent, if the degree of freedom is too high, it will give excessive stimulation to the inner cavity of the human body, and the pain caused by the massage will become stronger.

[0046] Based on this, it is preferable that the depth M of the recesses 5, 5a and 5b is 8 - 20 mm, and the angle between the inner wall surface and the bottom surface of the recesses 5, 5a and 5b is in the range of 90° - 135°.

[0047] When taking the above numerical values, the degree of freedom that the recess gives to the massage protrusion is within a desired range, and its operating space can be limited. Then, after the massage protrusion retracts to the limit position, the recess provides a degree of restraint to it, limits the massage area formed by the massage protrusion to a certain extent, reduces the risk of secondary damage caused by the massage area being too large, and makes the stimulating effect of the massage protrusion more concentrated to ensure the sensitivity of the somatic sensation stimulation.

[0048] As shown in FIG. 5, the in-body massage device 200 using the massage module 100 shown in the first embodiment includes at least a massage body 20. The massage body 20 may be curved, straight rod-shaped, wavy, etc. In this embodiment, the massage body 20 has a curved shape with a warped tip.

[0049] The massage module 100 is located at the tip of the massage body 20, constitutes the in-body end 21 of the massage body 20, and can be entirely inserted into the hole-shaped massage target site. In the direction away from the in-body end 21, a gripping end 23 used for the user to grip is formed.

[0050] Refer to FIGS. 7a and 7b. FIG. 7a is a schematic diagram when massaging a human body using the in-body massage device 200 shown in FIG. 5. FIG. 7b is a diagram schematically showing the usage state of the in-body massage device 300 using the massage module 100a shown in FIGS. 3a and 3b. When different massage modules are adopted, the obtained in-body massage device can bring different massage effects to the human body and meet the needs of different people.

[0051] In the present invention, the in-body massage device has all the beneficial effects of the aforementioned massage modules 100, 100a or 100b, and will not be described further here. Also, regarding the internal driving principle of the in-body massage device 200, reference can be made to the principle of the swinging mechanism or sliding mechanism of the related massage module in the prior art, and will not be described further here.

[0052] In the description of the embodiments of the present invention, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more of the embodiments or cases.

[0053] Although the embodiments of the present invention have been shown and described, those skilled in the art can make various changes, modifications, substitutions, and variations to these embodiments without departing from the principle and spirit of the present invention. The scope of the patent claims of the present invention is defined by the appended claims and their equivalents.
