Description

Technical Field

[0001] The present invention relates to the technical field of massage and pressure sore prevention equipment, and in particular to a push-pull core strip type massage component and a massage pressure sore prevention pad comprising the push-pull core strip type massage component. Background Art

[0002] Hemorrhoids and other common diseases around the anus are mostly characterized by symptoms such as bleeding, pain, itching, and anal swelling, which cause great trouble to patients' work and life.

[0003] Treatments for hemorrhoids are primarily divided into conservative and surgical treatments. Key preventative and remedial measures include: proper physical exercise, regular bowel movements, maintaining cleanliness around the anus, avoiding prolonged sitting, squatting, or standing, regular Kegel exercises (to strengthen the anal sphincter and pelvic floor muscles), and perianal massage. Appropriate perianal massage offers numerous benefits, such as promoting blood circulation, relieving muscle spasms, alleviating feelings of heaviness, and helping to reduce swelling.

[0004] Currently, there are many technologies for perianal massage, but the existing perianal massage devices mostly massage the anus through vibration. Due to the special location and varied shape of the anus, the vibration can only be transmitted to the buttocks, and it is impossible to deeply massage the perianal area and the corresponding acupuncture points, resulting in poor massage effect and poor practicality.

[0005] In this regard, the Chinese patent with the publication (announcement) number CN112870041B discloses a massage device for relieving pain in patients with anorectal diseases, which relates to the technical field of massage devices and solves the problem that the existing anorectal massage devices massage the anus by vibration, but the vibration can only be transmitted to the buttocks, and cannot deeply massage the perianal area and corresponding acupuncture points, resulting in poor massage effect. The massage device for relieving pain in patients with anorectal diseases includes a massage rod; the massage rod is inserted into the interior of the lifting block. The massage rod is used to massage the patient's anus in a wave-like cycle of rising and lowering, which makes the anus massage more extensive and in-depth, improves the massage effect on the patient's anus, relieves the patient's pain, and enhances the treatment effect.

[0006] However, the massage device still has the following problems: 1. It has a complex structure, is large and heavy, and has high production costs; 2. It needs to be installed with larger furniture such as seats before it can be used, and has poor adaptability; 3. It has high energy consumption.

[0007] In addition, it is well known that massaging the pressure area has the effect of promoting blood circulation and is also one of the measures to prevent or alleviate pressure sores. The Chinese patent with the publication (announcement) number CN104188772B discloses a self-service anti-bedsore massage wheelchair. Two sets of soft water pipes are arranged horizontally on the seat cushion of an ordinary wheelchair. Both sets of water pipes are continuous "E"-shaped structures and are arranged at intervals. One end of the soft water pipe is sealed and the other end is connected to a water-filled bladder. The bladder connected to the water pipe of group A is placed on the tray of the left wheelchair armrest, and the bladder connected to the water pipe of group B is placed on the tray under the right wheelchair armrest. There is a handle on the outer side of the front end of each armrest that can be pushed, pulled and rotated back and forth. There is a pressure plate in the middle of the handle that extends to the top of the bladder and is bonded to it; the soft water pipe is covered with a breathable fabric. After adopting the above technology, wheelchair users can self-massage to prevent the occurrence of bedsores without using power. Wheelchair users not only enjoy the massage, but also gain the pleasure of exercising their upper limbs.

[0008] However, the massage wheelchair still has the following problems: 1. The massage module needs to be connected to the wheelchair, the overall structure is complex, and the production cost is high; 2. The massage and anti-bedsore functions can only be carried out on the wheelchair, and the adaptability is poor; 3. Compared with ordinary wheelchairs, the extra handles easily hinder people with mobility difficulties from sitting on and leaving the wheelchair.

[0009] Therefore, a push-pull core strip type massage component and a massage anti-pressure sore pad are proposed. Summary of the Invention

[0049] Due to the adoption of the above technical solution, the advantages of the present invention are:

[0050] 1. The push-pull core strip massage component provided by the present invention adopts a massage ring to roll deeply and soothingly between the parts where the core strip contacts the body in a rolling and pressing manner. It can be used for focused massage of body parts such as shoulders and back, and is particularly suitable for perianal massage and pelvic floor muscle massage. The provided massage anti-pressure sore pad can be used as an anti-pressure sore pad to reduce or avoid the occurrence of pressure sores in states such as long-term sitting in a wheelchair, bed rest, and surgery. It can also be used as a buttocks massage cushion for people who sit for a long time in the office or for long distances. It has outstanding practical value.

[0051] 2. The push-pull core strip massage assembly provided by the present invention is easy to connect to functional modules such as inflatable parts, inner support parts, leg clamps (PC muscle trainers), and automatic drive devices to achieve further improvement in functions and / or performance.

[0052] 3. The present invention only requires easy pushing and pulling of the core strip along the length direction of the core strip to realize the rolling of the massage ring pressed under the body on the core strip. It is easy to operate by manual pushing and pulling, and easy to connect the driving device to realize automatic operation. It is easy, simple and convenient to use, and can avoid the problems of numbness caused by vibration massage in the existing technology, discomfort caused by too thin people, and powerless massage for too fat people.

[0053] 4. The massage ring provided by the present invention, which includes a ball portion and a connecting portion, can be particularly put on the upper limbs. As the upper limbs are raised and lowered, the massage ring rolls up and down under the action of gravity, performing a rolling massage on the upper limbs, which is beneficial to promoting blood circulation in the limbs and preventing thrombosis.

[0054] 5. The massage ring in the massage anti-pressure sore pad provided by the present invention can roll on the supported body part as the connecting rod moves. While achieving the change of body support position to prevent pressure sores, it can also perform rolling massage on a larger area of ​​the body.

[0055] 6. The main body of the present invention can be made entirely of elastomeric materials, and there will be no problem of air leakage and failure. In addition, each massage ring and each group of push-pull core strip massage components are independent units. Single or partial damage will not easily affect normal use. In addition, the component cost is low and maintenance and replacement are easy, making the use of the present invention more comfortable, safe and reliable.

[0056] 7. After the massage anti-bedsore pad provided by the present invention is laid under the body, during the process of pushing and pulling the connecting rod, the several massage rings pressed under the body are mainly translated under the drive of multiple core strips, rather than the existing anti-bedsore pads that use a relatively large range of alternating lifting and lowering support. As a result, during the process of changing the support position, the present invention is less likely to cause the body to fluctuate and affect the implementation of the operation, and it is convenient to manually and instantly complete the change of the body support point. When automatic drive is used, the patient's body will not interfere with the movement of the operation, so it can also be used as a measure to prevent pressure sores during surgery.

[0057] 8. The massage and anti-pressure sore pad provided by the present invention can be easily and flexibly placed where needed for use like a general seat cushion.

[0058] 9. The hardness of the present invention can be easily changed by adjusting the inflation volume or the propping degree of the core strip, and / or adjusting the inflation volume of the massage ring, so as to easily meet personalized needs.

[0059] 10. The present invention can be composed of a massage ring made of elastic material and sleeved on a core strip, which has a very simple structure, is easy to produce, has low cost, and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0099] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0100] The specific implementation method is now described as follows:

[0101] The present invention provides a push-pull core strip massage component 10 embodiment 1, see Figure 1 、 Figure 2 , including a core strip 11 and a massage ring 12 tightly fitted on the circumference of the core strip 11. When the massage ring 12 is pressed under the body, and then when the core strip 11 moves along its own length, the massage ring 12 rolls under the body and on the circumference of the core strip 11 under the action of friction.

[0102] In this embodiment, the core strip 11 is a bendable four-curved solid rod made of polyurethane, thermoplastic polyurethane or polyethylene (see Figure 2 ) or hollow rod (see Figure 3 、 Figure 4 ); Further, in order to improve the bending resistance of the core bar 11, a reinforcing core 112 is embedded in the core bar 11, see Figure 5 The massage ring 12 includes a ball portion 123 and a connecting portion 122, both ends of the connecting portion 122 are connected to the ball portion 123 to form a ring, and the massage ring 12 is made of an elastic material such as rubber. Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 Further, in order to facilitate the adjustment of the hardness, weight and other conditions of the massage ring 12 and expand the scene of massage and / or exercise needs, the air valve 40 can be connected to the massage ring 12, see Figure 6 、 Figure 10 Water, gas and other fluids can be injected into and discharged from the massage ring through the air valve 40.

[0103] The present invention provides a push-pull core strip massage component 10 embodiment 2, see Figure 11 The difference from Example 1 is that the massage ring 12 includes more ball parts 123 and more connecting parts 122 connected between the ball parts 123, and an air valve 40 is connected to one ball part 123, and the circumferential surface of the core strip 11 is provided with more arc surfaces that can cooperate with more (4) ball parts 123 on the massage ring 12 for transmission.

[0104] Furthermore, in the push-pull core strip massage component 10 embodiment 1 and embodiment 2 provided by the present invention, the massage ring 12 provided can also be used, for example, to be put on the upper limbs to perform straight arm raising and lowering movements, so that the massage ring 12 can roll and massage the upper limbs. Preferably, the number of ball parts 123 on the massage ring 12 is at least 2 and no more than 12.

[0105] The present invention provides a push-pull core strip massage component 10 embodiment 3, see Figure 12 、 Figure 13 、 Figure 14 , the difference from embodiment 1 is that the core strip 11 is a tube with a circular or elliptical cross-section, and the massage ring 12 is a ring with a circular or elliptical cross-section, see Figure 15 、 Figure 16 Further, in order to enhance the massage intensity, a protrusion 2 is provided on the outer surface of the massage ring 12, see Figure 17 , a protrusion is provided on the circumference of the massage ring 12, see Figure 18 ;

[0106] In addition, as another alternative to the connection between the core strip 11 and the massage ring 12 (ie, the core strip 11 and the massage ring 12 are connected by an adapting structure), see Figure 19 The core strip 11 has a through hole 111 and two annular grooves on its circumference. The through hole 111 is located between the two annular grooves. The axial cross-section of the massage ring 12 is C-shaped. The massage ring 12 has two opposite sides, which are provided with end rings 121 for sealingly connecting the two annular grooves on the circumference of the core strip 11. Figure 20 An annular groove is provided on the circumferential surface of the core strip 11, and an annular protrusion 2 is provided on the opposite circumferential surface of the massage ring 12 connected to the core strip 11 for sealing and connecting the annular groove on the circumferential surface of the core strip 11.

[0107] The present invention provides a push-pull core strip massage component 10 embodiment 4, see Figure 12 、 Figure 21 The difference from Example 3 is that there are two massage rings 12, and it also includes a cloth cover 13 that is sleeved on the outside of the massage ring 12 and connected to the core strip 11 at both ends through a sleeve ring 113, a plug 114 and a plug 14 respectively. The cloth cover 13 is provided with a pleated portion 131 for increasing the stretchability.

[0108] Furthermore, in order to prevent the core strip 11 from bending easily during the pushing process, an elastic strip 8 with good bending resistance (such as a carbon fiber strip or a polycarbonate strip) can be connected between the sleeve ring 113 and the plug 114. Figure 24 .

[0109] The present invention provides a push-pull core strip massage component 10 embodiment 5, see Figure 19 、 Figure 22 The difference from Example 3 is that the circumferential wall of the core strip 11 does not contain a through hole 111, but is provided with a convex surface 115 that can protrude toward the interior of the massage ring 12.

[0112] The present invention provides a push-pull core strip massage component 10 embodiment 8, see Figure 23 、 Figure 26 The difference from Example 6 is that the inflatable member 15 connected to the core strip 11 is replaced by an internal support member, and the internal support member includes a tension member 17, a brake line 18 and an adjustment handle 19. The tension member 17 includes a main frame 171, a lifting plate 173, a connecting rod 174 and a sliding rod 172 slidably connected to the main frame 171. The main frame 171 is connected to the cavity 1 of the core strip 11. The upper surface of the lifting plate 173 is clamped to the inner surface of the cavity 1 of the core strip 11. The connecting rod 174 is rotatably connected between the sliding rod 172 and the lifting plate 173 through the shaft 3. ; The adjusting handle 19 includes a thrust bearing 193, a fixed threaded tube 191 and a movable threaded tube 192 that are threadedly connected to each other, and the thrust bearing 193 is fixedly connected to the movable threaded tube 192 through a seat ring; the brake line 18 is connected to the fixed seat 181 at both ends of the sleeve 183, and is respectively connected to the end of the fixed threaded tube 191 away from the movable threaded tube 192 and one end of the main frame 171. The brake line 18 is connected to one end of the sliding rod 172 through one end of the steel wire core 182, and the other end of the steel wire core 182 is in contact with the shaft ring of the thrust bearing 193 through the end head 1821.

[0113] The present invention provides a push-pull core strip massage component 10 embodiment 9, see Figure 26 、 Figure 27 The difference from Example 8 is that the upper surface of the lifting plate 173 contacts the inner surface of the cavity 1 of the core strip 11, and the connecting rod 174 is rotatably connected between the sliding rod 172 and the lifting plate 173, and between the lifting plate 173 and the ear plate 1711 on the main frame 171 through the shaft 3.

[0114] The present invention provides a push-pull core strip massage component 10 embodiment 10, see Figure 1 、 Figure 2 、 Figure 28, the difference from Example 1 is that it also includes a cloth cover 13 and a leg clamp connector 50, wherein the cloth cover 13 is sleeved on the outside of the massage ring 12, and both ends are fixedly connected to the core strip 11; the leg clamp connector 50 includes a resistance adjusting knob pipe 51, a screw connecting rod 52 connected to the outside of the resistance adjusting knob pipe 51, a distance adjusting screw 53, a distance adjusting screw joint 54 and a tightening screw 55 threadedly connected to one end of the resistance adjusting knob pipe 51, an elastic hook rod 511 is provided on the peripheral wall of the resistance adjusting knob pipe 51, and a hook tooth 5111 is provided at the end of the elastic hook rod 511 away from the tightening screw 55; the distance adjusting screw 53 is threadedly connected to the lower part of the screw connecting rod 52, and the end of the distance adjusting screw 53 away from the hand-tightening part is rotatably connected to the distance adjusting screw joint 54, and the peripheral surface of the distance adjusting screw joint 54 is fixedly connected to one end of the core strip 11.

[0115] In this embodiment, there is at least one massage ring 12 sleeved on the core strip 11 .

[0116] The present invention provides a massage anti-pressure sore pad 100 embodiment 1, see Figure 29 , including two connecting rods 4 and multiple sets of push-pull core strip massage components 10, the two connecting rods 4 are respectively connected to one end of multiple core strips 11 on the multiple sets of push-pull core strip massage components 10.

[0117] The present invention provides a massage anti-pressure sore pad 100 embodiment 2, see Figure 30 、 Figure 31 、 Figure 32 The difference from Example 1 is that the outer surface of the push-pull core strip massage component 10 is covered with a cloth cover 13, and the end of the cloth cover 13 is connected to the end of the core strip 11 on the push-pull core strip massage component 10 by bonding or snapping, or connected to the connecting rod 4, and a bottom pad 16 is connected to the bottom of the cloth cover 13, and adjacent bottom pads 16 and adjacent cloth covers 13 are connected.

[0118] Conventionally, in order to improve the comfort of the massage anti-pressure sore pad, a soft cushion can be further laid on the cloth cover 13.

[0119] The present invention provides a massage anti-pressure sore pad 100 embodiment 3, see Figure 30 、 Figure 34 (In order to facilitate the display of the internal structure, the cloth cover is not shown), the difference from Example 2 is that it also includes a telescopic motor 22, and the telescopic motor 22 is connected between the connecting rod 4 and the bottom pad 16. By controlling the operation of the telescopic motor 22 (for example, connecting the telescopic motor 22 and the power supply control module through wires to achieve control, which is an existing conventional technology and will not be repeated here), the telescopic motor 22 can push and pull the core strip 11 of the push-pull core strip massage component 10 to achieve automatic massage and / or prevent pressure sores.

[0120] Conventionally, in order to reduce the number of telescopic motors 22 used, after at least strengthening the base pad 16 by means of a reinforcing core 112 or the like, a driving device such as a telescopic motor 22 is connected only between the base pad 16 at one end of the massage anti-pressure sore pad and the connecting rod 4 .

[0121] The present invention provides a massage anti-pressure sore pad 100 embodiment 4, see Figure 35 , which is different from Example 2 in that a transmission rod 6 is connected between the ends of the two connecting rods 4, and one end of the transmission rod 6 is connected to a bendable portion 7, see Figure 2 、 Figure 3 、 Figure 5 、 Figure 7

[0122] In this embodiment, the bendable portion 7 is made of an elastic material such as soft polyvinyl chloride or polyurethane.

[0123] The present invention provides a massage anti-pressure sore pad 100 embodiment 5, see Figure 36 , including two connecting rods 4, two sets of push-pull core strip massage components 10 connected between the two connecting rods 4, a cloth cover 13, a bottom pad 16 connected to the outside of the cloth cover 13, an L-shaped connecting plate 9, a drive component installation box 30, and a push-pull drive component 20 connected to the shell 31 of the drive component installation box 30, wherein the cloth cover 13 is sleeved on the outside of the push-pull core strip massage component 10, and the end of the cloth cover 13 is connected to the connecting rod 4 in a clamping manner through the plug 14 and the connecting end 32 of the drive component installation box 30; the L-shaped connecting plate 9 is connected to the push-pull drive component 2 0 and the bottom pad 16, the operation of the telescopic motor 22 is controlled by the control module 21 on the push-pull drive component 20, and then the telescopic motor 22 can push and pull the core strip 11 of the push-pull core strip massage component 10 to move back and forth along its own length direction, and at the same time drive the massage ring 12 on the core strip 11 to move back and forth. When the massage ring 12 is pressed under the body, the massage ring 12 rolls on the inner surface of the cloth cover 13 under the body and the circumference of the core strip 11 under the action of the friction between its own outer surface and the core strip 11, thereby realizing automatic massage and / or preventing pressure sores.

[0124] The method of using the present invention:

[0125] When the present invention is used for perianal massage, see Figure 1 、 Figure 11 、 Figure 12 、 Figure 21, place the section where the massage ring 12 is located on a stool (the height is selected so that the angle between the thighs and calves is about 90 degrees after sitting down), then sit on the stool so that the massage ring 12 is located below the anus, and then hold the core strip 11 extending out of the stool with one hand and push and pull it back and forth (the pushing and pulling amplitude is determined by the number and size of the designed massage rings 12 and personal needs. When the number of massage rings 12 is 1, the pushing and pulling amplitude is generally controlled at about 100mm. As the number of massage rings 12 increases, the pushing and pulling amplitude generally decreases exponentially; among them, the pushing and pulling frequency is generally recommended to be slow and low-frequency, which can be adjusted according to personal physique and needs). When one end of the core strip 11 is connected to the inflatable ball 15, see Figure 22 、 Figure 23 、 Figure 25 The difference in usage is that you can hold the inflatable ball 15 and push and pull it back and forth to massage. By squeezing the inflatable ball 15, you can inflate the core strip 11 and release the air through the air valve 40 to adjust the hardness and thus achieve the effect of adjusting the massage intensity. When the core strip 11 is connected to an inner support, see Figure 26 、 Figure 27 The difference in usage is that the threaded tube 192 can be turned clockwise or counterclockwise to adjust the amplitude of the wire core 182 pulling the sliding rod 172, and then the degree of the lifting plate 173 being adjusted through the connecting rod 174, thereby achieving the effect of adjusting the massage intensity. Figure 28 After the resistance adjustment knob pipe 51 on the leg clamp connector 50 is inserted into the resistance adjustment knob on the leg clamp, the tightening screw 55 is tightened so that the hook teeth 5111 hook the resistance adjustment knob, thereby connecting the present invention to the leg clamp. Then, the distance adjustment screw 53 is turned to adjust the massage ring 12 to be located under the anus. Finally, the leg clamp can be used normally while sitting upright on the present invention. During use of the leg clamp, the forward and backward movement of the resistance adjustment knob will drive the forward and backward movement of the leg clamp connector 50, which in turn drives the core strip 11 connected to the leg clamp connector 50 to move forward and backward, achieving rolling massage of the massage ring 12 under the anus.

[0126] When the present invention is used for back massage, preferably, a longer core strip 11 with a massage ring 12 in the middle can be used, and a long cloth cover 13 in an overlapping state can be put on the outer cover of the core strip 11 and the massage ring 12, and the two ends of the cloth cover 13 are connected to the outside of the core strip 11 close to the massage ring 12. In this way, the two ends of the core strip 11 can be held by hand to pull back and forth to perform a scrubbing action, which is especially used for self-local massage of hard-to-reach parts of the body such as the shoulders and back (the massage ring 12 is placed in the position to be massaged). In order to increase the intensity of the massage, the massage ring 12 can also be pressed between the body and the wall.

[0127] When the present invention is used for upper limb massage, the preferred embodiment is shown in FIG. Figure 10 、 Figure 11The massage ring 12 is filled with a high-density fluid such as water through the air valve 40 and then put on the arm. Then, by repeatedly lifting and lowering the massage ring 12, the massage ring 12 can be rolled back and forth on the upper limb to massage the upper limb and prevent thrombosis.

[0128] When the present invention is used as a massage anti-pressure sore pad 100 on a wheelchair, see Figure 30 , place the massage anti-pressure sore pad 100 on the wheelchair cushion, with a connecting rod 4 facing the front of the wheelchair cushion (including the bendable part 7, see Figure 35 , with the connecting rod 4 near the bendable portion 7 facing forward), and then sitting on the massage cushion 100, the wheelchair user or others can push and pull the connecting rod 4 to massage the buttocks and change the buttocks support point, thus preventing pressure sores. Obviously, the massage cushion 100 provided by the present invention is also very suitable as a massage cushion for people who take long-distance buses, and for people who sit for long periods of time in the office to massage the buttocks and legs.

[0129] When the present invention is used as a massage anti-pressure sore pad 100 on a bed, see Figure 30 、 Figure 35 Place the massage anti-pressure sore pad 100 under the patient, especially on the sacrum and coccyx where pressure sores are prone to occur. Push or pull it several times every once in a while (for example, 2 hours) (to achieve the change of the support point of the massage ring 12 on the body), or push and pull it repeatedly several times (to achieve the effect of massage and anti-pressure sore). The push and pull amplitude is about 10mm, which is related to the designed rolling stroke of the massage ring 12. Figure 34 、 Figure 36 When a driving component and a power supply control module are provided in the massage and pressure sore prevention pad, automatic massage and / or pressure sore prevention can be achieved.

[0130] When the present invention is used as a massage anti-pressure sore pad 100 during surgery, see Figure 30 , place the massage anti-pressure sore pad 100 on the part of the patient to be treated for pressure sores (e.g., the sacrum), and at regular intervals, during a brief break of 1 second during surgery, pull or push the connecting rod 4. When automatic pressure sore prevention is required, a driving component and a power supply control module can be provided in the massage anti-pressure sore pad 100. For example, the driving component can be controlled to drive the connecting rod 4 to complete one push-pull action per hour (based on a total push-pull stroke of 20 mm, the speed at which the connecting rod 4 drives the massage ring 12 to roll is approximately 0.00556 mm per second, which is much smaller than the body movement caused by human breathing, and mainly performs ultra-short-distance translation, so it will not interfere with the surgery).

[0131] The massage ring 12 provided by the present invention can roll between the core strip 11 and the human body when the human body presses against the core strip 11.

[0132] Due to the friction between the massage ring 12 and the core strip 11, and / or the existence of an adapting structure such as the raised ring / end ring 121 and the annular groove on the core strip 11, when the massage ring 12 is pressed by the human body, during the pushing and pulling of the core strip 11, the outer peripheral surface of the massage ring 12 is subjected to the friction of the cloth cover 13 or the skin or the clothing outside the skin. At the same time, due to the elastomeric annular structure of the massage ring 12 (especially including the central cavity 1 structure), the core strip 11 moving along its length direction will apply a tangential force to the close contact part (inner annular surface) and / or the adapting connection structure of the massage ring 12 thereon, causing the inner and outer annular surfaces of the massage ring 12 to undergo a switching flipping motion (i.e., rolling along the length direction of the outer peripheral surface of the core strip 11), thereby driving the massage ring 12 to roll between the core strip 11 and the human body. Due to the padding and guiding effect of the cloth cover 13, the rolling process of the massage ring 12 between the core strip 11 and the human body is not easily obstructed. A real-life example: insert a silicone tube with an outer diameter of 14mm and a wall thickness of 4mm into the center hole of an "uncatchable water bag" (a relaxing and prank toy sold on online shopping platforms). Press the "uncatchable water bag" with your palm. When pushing and pulling the silicone tube along its length, the "uncatchable water bag" will easily roll between the silicone tube and your palm, and the force required to push and pull the silicone tube is very small.

[0133] When the massage ring 12 is tightly fitted on the core strip 11, the rolling distance of the massage ring 12 is mainly affected by the distance between the convex surface 115 on the core strip 11 and the two sides of the massage ring 12, and / or by the fixed positions of the two ends of the cloth cover 13 on the core strip 11; when the massage ring 12 is connected to the core strip 11 with an adapter structure, the rolling distance of the massage ring 12 mainly depends on the length of the massage ring 12 minus the width of the adapter structure.

[0134] The above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications based on the above description are possible. It is not possible to enumerate all embodiments here. Any obvious variations or modifications arising from the technical solutions of the present invention remain within the scope of protection of the present invention.
