Perineum massage device

Abstract

According to the perineum massage device, a massage module adopts four adjusting pipes, the bending direction and angle of an inner sleeve can be controlled by controlling the pressure in each adjusting pipe, and a plurality of pressing modes can be realized by combining the rotation of a massage ball, so that the finger massage process and manipulation can be truly restored, and a better massage effect can be obtained. In addition, hot compress fluid can be introduced into the inner tube cavity to heat the inner tube, so that the comfort and the massage effect are improved. Certainly, the electric heating wire can be adopted for heating instead of being connected with hot compress fluid, which is only high in safety and does not adopt the hot compress fluid in the prior art. The vulva part is kneaded and pressed by the kneading and pressing head, and during kneading and pressing, the kneading and pressing head can be driven by the kneading and pressing ball to move relative to the vulva so as to realize sliding kneading and pressing. Meanwhile, the kneading and pressing head also plays a role in positioning the inner sleeve, and the distance between the inner sleeve and the vaginal orifice can be judged by utilizing the pressing of the kneading and pressing head and the vulva, so that the depth of the inner sleeve inserted into the vaginal orifice is controlled.

Description

Technical Field

[0001] The present invention relates to a perineum massage auxiliary device, in particular to a massage module and a perineum massage device. Background Art

[0002] In the field of obstetric care, perineal massage has been widely recognized and applied as a preventive measure to reduce the risk of perineal tears and promote postpartum recovery. Traditional perineal massage is usually performed manually by midwives or medical staff. Through manual massage and pressure on the perineum, it aims to enhance the flexibility and elasticity of the perineal muscles, promote blood circulation, and thus reduce the risk of perineal injury during delivery.

[0003] However, existing perineal massage methods have some limitations. Although manual massage can be performed by pregnant women or their families at home, many pregnant women and their families are often worried about the risks of the operation and fear that improper techniques may cause harm to themselves or the fetus. Therefore, they prefer to go to the hospital for professional operation. This not only increases the time and economic cost of pregnant women returning to the hospital, but also increases the consumption of medical resources. In addition, manual massage relies on the operator's experience and skills. The massage strength, frequency and duration are difficult to control accurately, resulting in unstable massage effects. Moreover, traditional massage methods cannot provide auxiliary functions such as warming, and the warming function has been proven to further promote blood circulation and enhance the massage effect.

[0004] Although there are some vaginal massagers on the market, most of them are sex toys or assist in postpartum pelvic floor treatment. They do not have massage functions specifically designed for the perineum of pregnant women and cannot meet the special needs of perineal massage in prenatal care.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0021] See also Figures 1-10 The perineal massage device of this embodiment includes a housing 210, a kneading module 300, and a massage module 400. The housing 210 houses a tank 220, an expansion pump 230, a first electric cylinder 610, a first slide rail 241, and an electrical box 100. The tank 220 is hollow and used to store liquid. The first slide rail 241 engages and slides with a main slide 250. The main slide 250 is assembled with a first electric cylinder shaft 611, which is installed within the first electric cylinder 610. When the first electric cylinder 610 is activated, the first electric cylinder shaft 611 expands and contracts, thereby driving the main slide 250 to move synchronously. The electrical box 100 houses the corresponding electrical components, such as a battery, a main control chip (MCU), and a motor driver.

[0022] The main slide 250 is also mounted with a second slide rail 242 and a third slide rail 243. These second slide rails 242 and third slide rails 243 engage and slide with the side slide 260 and longitudinal slide 270, respectively. The side slide 260 is mounted with the kneading module 300, while the longitudinal slide 270 is mounted with the massage module 400. The side slide 260 is assembled with a second electric cylinder shaft 621, which is installed within a second electric cylinder 620, which is mounted on the main slide 250. When activated, the second electric cylinder 620 drives the shaft 621 to extend and retract, thereby driving the side slide 260 and, consequently, the kneading module 300 to slide synchronously.

[0023] The longitudinal slide 270 is assembled with the third electric cylinder shaft 631, which is installed in the third electric cylinder 630, which is mounted on the main slide 250. When the third electric cylinder 630 is activated, the third electric cylinder shaft 631 extends and retracts, thereby driving the longitudinal slide 270 and, consequently, the massage module 400 to move synchronously.

[0024] See also Figures 1-15The kneading module 300 includes a kneading seat 310, a kneading ball 320, a kneading wheel 330, a protective cover 340, and a telescopic cylinder 350. The kneading seat 310 is mounted on the side sliding seat 260. The kneading seat 310 and the kneading ball 320 are spherically hinged. The kneading ball 320 is pressed against the kneading wheels 330 in two directions. When in use, the kneading wheels 330 in these two directions control the rotation direction of the kneading ball 320. The kneading wheels 330 are mounted on the kneading wheel shaft 331, which is mounted on the kneading seat 310. The two kneading wheel shafts 331 in different directions are respectively connected to the output shafts of the first kneading motor 661 and the second kneading motor 662. The first kneading motor 661 and the second kneading motor 662 are both mounted on the kneading seat 310. When in use, the kneading ball 320 can be controlled to rotate by controlling the two kneading wheels to rotate in different directions through the first kneading motor 661 and the second kneading motor 662. The first kneading motor 661 and the second kneading motor 662 use servo motors, so the rotation angle and vector of the kneading ball 320 can be calculated.

[0025] The kneading ball 320 is assembled and fixed to the outer shell of the telescopic cylinder 350, and a piston 361 is installed inside the telescopic cylinder 350 for sliding and sealing. The telescopic cylinder 350 is divided into a first piston chamber 351 and a second piston chamber 352 by the piston 361. The piston 361 is installed on the piston rod 360, and one end of the piston rod 360 passes through the second piston chamber 352 and is assembled with the connecting disk 362. The first piston chamber 351 and the second piston chamber 352 are respectively installed with a first piston spring 301 and a second piston spring 302. The first piston spring 301 and the second piston spring 302 are used to provide elastic damping for the movement of the piston 361.

[0026] The first piston chamber 351 and the second piston chamber 352 are respectively connected to the first tube head 353 and the second tube head 354, and the first tube head 353 and the second tube head 354 are respectively connected to the first reversing tube 531 and the second reversing tube 532 of the reversing device 500. When in use, the reversing device 500 is used to switch the supply of fluid to the first piston chamber 351 and the suction of the second piston chamber 352, or the suction of the first piston chamber 351 and the supply of fluid to the second piston chamber 352, so that the reciprocating movement of the solid line piston can realize intermittent pressure massage.

[0027] The connecting disk 362 is mounted within a pressure sleeve 642 and secured to the input disk 641 of the pressure sensor 640. The pressure sensor 640 is mounted within the pressure sleeve 642, which is then secured to the housing of the motor 650. During use, the pressure sensor 640 detects the axial pressure applied to the piston rod 360, which serves as the reaction force of the kneading massage.

[0028] The motor 650 includes a motor cavity 651 with a hollow interior, and an impeller 652 is installed in the motor cavity 651. The impeller 652 is fixed on the motor shaft 653. One end of the motor shaft 653 passes through the motor 650 and is assembled with the connecting seat 370. The connecting seat 370 is provided with a connecting seat hole 372, and a connecting platform 371 is provided in the connecting seat hole 372.

[0029] One end of the kneading rod 380 is inserted into the connecting base hole 372, and the connecting hole 381 on this end of the kneading rod 380 is inserted into the connecting base 371. The connecting hole 381 and the connecting base 371 are assembled so as to be non-rotatable relative to each other, thereby allowing the motor 650 to directly drive the kneading rod 380 to rotate. The connecting base 371 and the connecting hole 381 have an interference fit, so that the kneading rod 380 and the connecting base 370 are assembled by a clamping force.

[0030] The other end of the kneading rod 380 is assembled with the kneading platform 710, and the kneading platform 710 is assembled with the kneading head 720. The interior of the kneading head 720 is a hollow kneading cavity 722, and a number of kneading holes 721 are provided on the side wall. The kneading holes 721 are connected to the kneading cavity 722. A sponge block 730 is installed in the kneading cavity 722, and the sponge block 730 is soaked with lubricating liquid. When in use, the kneading head 720 is pressed against the vulva to achieve kneading. During this process, the sponge block 730 is continuously squeezed so that the lubricating liquid leaches out from the kneading holes 721 to achieve lubrication. The kneading head 720 is designed as an ellipsoid, so that different parts can be pressed intermittently to achieve a better pressing effect.

[0031] In some embodiments, the connecting base 370 is assembled with one end of the shield 340, and the other end of the shield 340 is assembled with the kneading base 310. The shield 340 is elastic and covers the motor 650 and the telescopic cylinder 350 for isolation and protection. The shield 340 is provided with a shield tube 341 for wiring.

[0032] In some embodiments, one end of the adjusting rod 390 passes through the kneading ball 320 and is rotated into the first piston chamber 351, and an adjusting pin 391 is installed on this end. The adjusting rod 390 is installed in the first piston spring 301 and the adjusting pin 391 passes through the spiral gap of the first piston spring 301. When the adjusting rod 390 is rotated, the first piston spring 301 can be adjusted in its length direction through the adjusting pin 391 to adjust the extrusion force of the first piston spring 301 on the piston 361 in the initial state, thereby adjusting the extrusion stroke and extrusion force.

[0033] The other end of the adjusting rod 390 passes through the kneading ball 320 and is assembled on the knob 392 and the pointer 393 respectively. The pointer 393 cooperates with the scale on the scale ring 321 to determine the adjustment length of the first piston spring 301. The scale ring 321 is set or fixed on the kneading ball 320.

[0034] See also Figures 1-10 、 Figure 16-Figure 25 The massage module 400 includes a massage seat 410, a massage ball 420, massage wheels 430, and a plug-in tube 440. The massage seat 410 is mounted on the longitudinal sliding seat 270. The massage ball 420 is mounted on the massage seat 410 and spherically hinged thereto. There are at least two massage wheels 430, one located in each direction of the massage ball 420. Each massage wheel 430 is mounted on a corresponding massage wheel shaft 431, which is mounted on the massage seat 410. The massage wheel shaft 431 in one direction is connected to the output shaft of a first massage motor 671, and the massage wheel shaft 431 in the other direction is connected to the output shaft of a second massage motor 672. The first massage motor 671 and the second massage motor 672 are both mounted on the massage seat 410. During use, the massage balls 420 are rotated by driving the corresponding massage wheel shafts 431 using the first massage motor 671 and the second massage motor 672, respectively. The first massage motor 671 and the second massage motor 672 are servo motors.

[0035] The massage ball 420 is mounted with a socket 421, which is inserted into a socket hole 441 of the socket tube 440. The screw 401 passes through the socket tube 440 and is assembled with the socket 421, thereby achieving stable assembly of the socket 421 and the socket tube 440. The socket hole 441 and the socket 421 are both hexagonal, so that the socket 421 and the socket 421 cannot rotate relative to each other.

[0036] The plug tube 440 is assembled with one end of the inner sleeve 460. The inner sleeve 460 has a hollow inner sleeve cavity 461. A sealing plug 462 is installed on the end of the inner sleeve 460 near the plug tube 440. A lubricating sleeve 490 is installed on the outer side of the inner sleeve 460 near the plug tube 440. The lubricating sleeve 490 has a hollow lubricating cavity 491 inside. The lubricating sleeve 490 is also provided with a filling pipe 493, which is connected to the lubricating cavity 491 and is sealed by a pipe cap 492. During use, the pipe cap 492 can be opened and lubricating liquid can be added to the lubricating cavity 491 through the filling pipe 493.

[0037] The lubricating sleeve 490 is assembled with one end of the hole sleeve 450. The hole sleeve 450 is sleeved on the outside of the inner sleeve 460, and a hole sleeve cavity 451 is formed between the inner side of the hole sleeve 450 and the outer side of the inner sleeve 460. The hole sleeve cavity 451 is connected with the side groove 494. The side groove 494 is provided on the lubricating sleeve 490 and connects the hole sleeve cavity 451 with the lubricating cavity 491, thereby introducing the lubricating liquid in the lubricating cavity 491 into the hole sleeve cavity 451.

[0038] The outer side of the inner sleeve 460 is provided with several inner sleeve ridges 402 extending along its axial direction. A ridge groove 463 is formed between two inner sleeve ridges 402. The inner sleeve ridges 402 are fixed to the inner wall of the hole sleeve 450, thereby securing the hole sleeve 450 to the inner sleeve 460. The hole sleeve 450 is provided with several small, penetrating lubrication holes 452. The hole sleeve 450 is elastic, and in its initial state, the hole sleeve 450 seals the lubrication holes 452 through its own elastic force. While the lubricant in the hole sleeve cavity 451 initially has difficulty penetrating the hole sleeve 450, during use, the lubricant slowly seeps out through internal squeezing and bending, thereby providing lubrication. The greatest advantage of this method is that it prevents excessive lubricant leakage, which could affect its use.

[0039] A plurality of support rings 480 are installed in the inner sleeve 460, and a penetrating support ring hole 481 is provided on the support ring 480. The support ring hole 481 is used to connect the inner sleeve cavities 461 on both sides. The support ring 480 is assembled with four adjustment tubes and an inner tube 740. The inner tube 740 is installed on the inner side of the four adjustment tubes, and one end of the inner tube 740 is assembled with the massage head 470. The massage head 470 is installed between the ends of the inner sleeve 460 and the hole sleeve 450. The other end of the inner tube 740 passes through the sealing plug 462 and is connected to the temperature tube. The adjustment tube includes an angle tube 750 and a telescopic tube 760. The angle tube 750 is assembled with the support ring 480, and the two angle tubes 750 are connected and internally communicated by the telescopic tube 760. The telescopic tube 760 has telescopic elasticity. The angle tube 750 closest to the massage head 470 is assembled with the massage head 470, and the angle tube 750 closest to the massage ball 420 is connected to the pressure tube after passing through the sealing plug 462.

[0040] The inner tube 740 is elastic and is used to support the inner sleeve 460 and provide elastic resistance to the bending of the inner sleeve 460 so as to facilitate subsequent automatic reset. The inner sleeve, hole sleeve, and angle tube 750 are all made of elastic material, so that they have a certain degree of support elasticity.

[0041] When in use, the bending angles of the inner sleeve 460 and the hole sleeve 450 can be adjusted as needed to adapt to different massage effects. Figure 23 To achieve downward bending, pressurize the upper adjustment tube and depressurize the lower adjustment tube. This allows for upward and downward bending by extending the upper telescopic tube 760 and retracting the lower telescopic tube 760. Similarly, to bend from right to left, pressurize the right adjustment tube and depressurize the left. This design simulates the bending of a human finger, resulting in a more effective massage.

[0042] The sidewall of the inner tube 740 is further provided with a plurality of inner tube holes 742 extending therethrough. The inner tube holes 742 are in communication with the inner tube cavity 741, which is disposed within the inner tube 740. The inner diameter of the inner tube holes 742 gradually increases from the end near the sealing plug 462 to the end near the massage head 470. This design is primarily intended to allow the inner tube cavity 741 to evenly deliver the hot compress fluid into the inner sleeve cavity 461 as much as possible according to pressure changes. The inner sleeve cavity 461 is in communication with the return pipe 464. When the inner sleeve 460 needs to be heated, a fluid (e.g., water) of a certain temperature is input into the inner tube cavity 741 through the temperature control tube. After entering the inner tube cavity 741, the water sequentially passes through the inner tube holes 742 into the inner sleeve cavity 461, then passes through the various support ring holes 481, and finally enters the return pipe 464 for output circulation. In this way, the temperature of the hole sleeve 450 can be adjusted to enhance massage comfort.

[0043] See also Figures 26-30 The commutator 500 includes a reversing motor 680, a reversing housing 510, and a valve core 540. A valve hole 511 is provided inside the reversing housing 510. The valve hole 511 is sealed and rotatably assembled with the valve core 540. A first flow channel 541 and a second flow channel 542 are provided on the valve core 540. Four connecting grooves 512 are provided on the inner side of the valve hole 511. The four connecting grooves 512 are respectively connected to the first reversing pipe 531, the second reversing pipe 532, the first connecting pipe 521, and the second connecting pipe 522; in the initial state, the first flow channel 541 connects the first connecting pipe 521 with the first reversing pipe 531, and the second flow channel 542 connects the second connecting pipe 522 with the second reversing pipe 532. The first connecting pipe 521 is connected to the output port of the telescopic pump 230, and the second connecting pipe 522 is connected to the inlet of the telescopic pump 230. The first reversing tube 531 is connected to the first pipe head 353 through a first pipe, and the second reversing tube 532 is connected to the second pipe head 354 through a second pipe.

[0044] The valve core 540 is assembled with the output shaft of the reversing motor 680. When the reversing motor 680 is activated, it drives the valve core 540 to rotate, thereby switching the input direction. Specifically, in the initial state, the first reversing tube 531 inputs fluid (water or gas) through the first pipe into the first piston chamber 351, driving the piston toward the kneading platform 710 and applying pressure. The fluid in the second piston chamber 352 enters the inlet of the telescopic pump 230 through the second pipe, thereby circulating. The reversing motor 680 is then activated, rotating the valve core 90 degrees, so that the first flow channel 541 connects the second connecting pipe 522 with the first reversing tube 531, and the second flow channel 542 connects the first connecting pipe 521 with the second reversing tube 532. At this point, the first pipe reverses flow, while the second pipe inputs fluid into the second piston chamber, driving the piston back to its original position. By adjusting the speed of the reversing motor 680, the reciprocating frequency of the piston, and thus the pressing frequency, can be controlled. Furthermore, by adjusting the power of the reversing motor 680, the pressure applied can be adjusted, thereby controlling the pressing force.

[0045] Although the reversing device can be replaced by a reversing valve, it requires high-frequency reversing, which is difficult for the reversing valve to meet. At the same time, the use of a reversing valve will seriously affect its life.

[0046] See also Figure 31 Each adjustment tube is connected to the outlet of a reversing valve via a corresponding branch tube. The inlet of the reversing valve is connected to the outlet of a branch pump, which in turn is connected to the fluid. The reversing valve connects the branch tube to either the branch pump or the tank 220, which stores the fluid. The branch tubes are connected to the inlet of a branch sensor (a hydraulic or pneumatic sensor) to detect the fluid pressure within the branch tube. Controlling the internal pressure of the four adjustment tubes controls the bending of the inner sleeve. The branch sensors, combined with pre-test data, can roughly estimate the bending angle for easier massage control.

[0047] The rotary pump pumps the fluid into the motor cavity to drive the motor to run. A motor sensor (hydraulic sensor or air pressure sensor) is installed on this pipeline. The motor power can be calculated by detecting the pressure of the fluid input to the motor through the motor sensor, thereby controlling the speed of the kneading head.

[0048] The hot compress fluid is stored in a bottle and can be liquid (water) or gas. The inlet of the hot compress pump is connected to the hot compress fluid, and the outlet of the hot compress pump is connected to the heater. The heater heats the fluid and sends it into the temperature control valve. The temperature control valve controls the fluid temperature and closes once it exceeds the preset temperature to prevent scalding (the temperature control valve can be omitted). Finally, the hot compress fluid is sent into the inner tube cavity, and the fluid is sent back from the return pipe to the device for storing the hot compress fluid to complete the cycle.

[0049] The operation process of this embodiment is roughly as follows: S100, vulva massage S110. The pregnant woman lies on the bed with her legs bent and spread out, and then installs the present invention so that the hole sleeve is aligned with the middle part of the vagina.

[0050] S120, using the two second electric cylinders to adjust the position of the kneading heads and the vulva until the kneading heads are aligned with the preset position of the vulva. Activating the first electric cylinder drives the main slide toward the vagina so that the two kneading heads are close to the vulva in the middle of the vagina.

[0051] S130: The first and second kneading motors are activated to adjust the kneading head to the desired location. The first electric cylinder is then activated to press the kneading head against the vulva. A pressure sensor detects initial pressure, and the adjustment lever 390 can be adjusted in advance to control massage pressure and stroke.

[0052] S140. Input fluid into the telescopic cylinder and motor to drive the piston to move axially back and forth and the kneading head to rotate for massage. Start the reversing motor to continuously switch the direction of the input to the telescopic rod. At the same time, use the pressure sensor and motor sensor to roughly detect the corresponding massage state and control it through the program. During the massage process, the first kneading motor and the second kneading motor can be started to control the movement of the kneading head relative to the vulva to achieve a wider range of kneading.

[0053] S150: After the massage is completed, the kneading and pressing head returns to the position pressed against the vulva in S130, and then stops, waiting for vaginal massage. Of course, in actual use, S100 can be omitted and vaginal massage can be performed directly. In this case, the kneading and pressing head plays the role of detecting the distance between the hole sleeve and the vagina, so that the massage module 400 can be controlled to only be inserted into the vagina 2-3 cm. If the insertion amount is too large, it may cause danger, and if the insertion amount is too small, there will be no massage effect.

[0054] S200, vaginal massage S210: After the two kneading heads are pressed against the vulva and positioned, the third electric cylinder is activated to drive one end of the orifice sleeve into the vagina 2-3 cm. Specifically, the orifice sleeve is at its farthest point from the vagina when the two kneading heads are pressed against the vulva as a reference. The axial displacement of the orifice sleeve is then calculated, and the third electric cylinder is used to control the orifice sleeve to achieve this displacement. Of course, the position of the open end of the orifice sleeve relative to the vagina can be adjusted by the first massage motor 671 and the second massage motor 672.

[0055] S220. According to the requirements of the bending angle, media of different pressures are input into the four adjustment pipes, so that the inner sleeve and the hole sleeve are bent, and the bending angle is determined by the corresponding branch pipe sensor.

[0056] S230. Start the first massage motor 671 and the second massage motor 672 respectively to drive the inner sleeve and the hole sleeve to rotate along the vaginal opening to achieve massage. This is similar to the U-shaped piston circle massage. When a point massage is needed, it can be switched by controlling the bending and straightening of the hole sleeve.

[0057] S300: After the massage is completed, the kneading rod 380 and the plug-in tube 440 can be pulled out for cleaning, disinfection or replacement. Example

[0058] See also Figure 32-Figure 36 The difference between this embodiment and the first embodiment is that the present embodiment is changed to a handheld type, which is more portable and more convenient to use, and can be used at home.

[0059] The device comprises a protective shell 810, on which is mounted a screw 820, which is inserted into and threadedly engaged with a first support screw sleeve 830. The protective shell 810 is assembled with one end of a handle 840, the other end of which is inserted into and threadedly engaged with a second support screw sleeve 850. During use, the height of the inner sleeve 460 can be adjusted by adjusting the depth of engagement between the handle 840 and the second support screw sleeve 850, and between the screw 820 and the first support screw sleeve 830, thereby adapting the device to different sizes of pregnant women.

[0060] Two kneading modules 300 and one massage module 400 are installed in the protective shell 810. Compared with the first embodiment, the kneading module 300 does not include the protective cover 340, the telescopic cylinder 350, the motor 650, and the pressure sensor 640, and the connecting seat 370 is directly installed on the kneading ball 320.

[0061] Compared with the first embodiment, the massage module 400 does not have the hole sleeve 450, the lubricating sleeve 490, and the inner sleeve ridge 402. Lubrication can be done by manually applying lubricating liquid on the inner sleeve 460.

[0062] When using the device, refer to the instructions in Example 1, but begin by aligning the inner sleeve with the vaginal opening and pressing the kneading head firmly against the vulva. The device's batteries and other related equipment are housed within the protective case 810 or the handle. Control can be via a wireless remote control or button 601, which is mounted on the protective case 810. Example

[0063] See also Figure 37-Figure 38 , which is further streamlined and optimized on the basis of the second embodiment, mainly to retain the basic functions and ensure portability and ease of operation.

[0064] The kneading module 300 no longer utilizes a kneading seat 310, kneading ball 420, first kneading motor 661, and second kneading motor 662. Instead, the kneading rod 380 is directly assembled with the output of the kneading motor (not shown). The kneading motor housing is mounted within a protective housing 810. This allows the kneading motor to drive the kneading head 720 to rotate for kneading. Of course, the kneading motor can also be omitted, and the kneading rod 380 can be mounted directly within the protective housing 810. In this case, the kneading head 720 primarily serves as a limiter, limiting the depth of insertion of the inner sleeve 460 into the vagina.

[0065] The massage module 400 does not utilize a massage seat 310, massage balls 420, a first massage motor 671, and a second massage motor 672. Instead, it utilizes a plug-in tube 440 and the output assembly of a massage motor (not shown). The massage motor housing is housed within a protective housing 810. During use, four adjustment tubes control the curvature of the inner sleeve 460, causing the end of the inner sleeve to enter the vaginal cavity and hook outward. The massage motor is then activated to rotate the inner sleeve 460, massaging the entire vaginal opening. Of course, the curvature of the inner sleeve 460 can be adjusted in real time to achieve multiple massage locations, taking into account the physiological structure of the vaginal opening.

[0066] This embodiment is designed primarily for ease of home use, offering simple functionality and ease of operation while retaining the most basic vaginal massage function. Embodiments 1 and 2 are suitable for professional medical institutions due to their comprehensive functionality, albeit at a slightly higher cost and requiring relatively professional operation. Furthermore, embodiment 2 can be considered an upgraded version of embodiment 3 and can also be used for home massage or simple clinical care.

[0067] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0068] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
