Description

Technical Field

[0001] This utility model relates to the field of obstetric and gynecological equipment, and in particular to an adjustable resistance gynecological pelvic floor muscle exercise device. Background Technology

[0002] Prenatal pelvic floor muscle exercises can help mothers better adapt to the expansion forces of the fetus on the birth canal during childbirth, thereby reducing the risk of perineal tearing. For example, Chinese utility model patent CN219921973U discloses an adjustable pelvic floor muscle exercise device, including an internal clamping exercise mechanism and a damping elastic mechanism, as well as a buttock pad. The internal clamping exercise mechanism includes an upper crossbar, a lower crossbar, a movable connecting plate, an arc-shaped clamp, and a manual bolt. The damping elastic mechanism includes a U-shaped frame, a threaded rod, a telescopic rod, and a return spring. A limit baffle is fixed to the top end of the buttock pad, and symmetrically distributed arc-shaped positioning plates are fixed to both ends of the limit baffle.

[0003] However, the existing adjustable pelvic floor muscle training devices still have some shortcomings in actual use: their resistance adjustment mainly relies on changing the position of the movable connecting plate. By adjusting the fixed position of the movable connecting plate on the relevant rods, the lever arm is changed. This adjustment method is cumbersome, requiring the user to manually loosen, move, and re-fix the movable connecting plate. Not only are there many adjustment steps and it is time-consuming, but it is also difficult to quickly and conveniently adjust the resistance to a suitable intensity according to one's own feelings during exercise, which affects the ease of use of the device. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable resistance gynecological pelvic floor muscle exercise device. This invention achieves rapid and convenient adjustment of the exercise resistance through the damping force of a spring and adjusting knob.

[0005] The technical solution of this utility model: an adjustable resistance gynecological pelvic floor muscle exercise device, including a main frame, on which symmetrical smooth rods are provided, and a pair of sliding seats are provided on the smooth rods, with kneeling pads on the sliding seats; a handrail is provided on the front side of the main frame; a damping element is provided between the two sliding seats, the damping element including a fixed cylinder connected to one side of the sliding seat and a sliding rod connected to the other side of the sliding seat, the sliding rod being embedded in the fixed cylinder; the fixed cylinder has a threaded part, on which an adjustment knob is fitted, and a spring is fitted on the sliding rod and the fixed cylinder, one end of the spring abutting against a ring on the sliding rod, and the other end of the spring abutting against one end of the adjustment knob.

[0006] In the aforementioned adjustable resistance gynecological pelvic floor muscle exercise device, the bottom of the main frame has a support rod, and both ends of the support rod have anti-slip feet.

[0007] In the aforementioned adjustable resistance gynecological pelvic floor muscle exercise device, the two ends of the main frame are provided with grip bars for easy hand support by the mother.

[0008] In the aforementioned adjustable resistance gynecological pelvic floor muscle exercise device, the sliding seat includes a seat body mounted on a smooth rod, with main rollers and auxiliary rollers arranged around the seat body, the main rollers and auxiliary rollers respectively fitting against the upper and lower surfaces of the smooth rod; the kneeling pad is mounted on the upper surface of the seat body.

[0009] In the aforementioned adjustable resistance gynecological pelvic floor muscle exercise device, the sliding rod includes a main rod, one end of which is embedded in a fixed cylinder, and the other end of the main rod has an annular plate. One end of the spring abuts against the annular plate, and one side of the annular plate has a connector that connects to a sliding seat on one side.

[0010] In the aforementioned adjustable resistance gynecological pelvic floor muscle exercise device, the adjustment knob includes a main ring that mates with the threaded portion, the other end of the spring abuts against the main ring, and the outer side of the main ring has a side support.

[0011] In the aforementioned adjustable resistance gynecological pelvic floor muscle exercise device, the kneeling pad includes a base plate connected to the seat body, the base plate having a sponge pad, and the sponge pad having an arc-shaped groove adapted to the calf of the postpartum woman.

[0012] Compared with the prior art, the present invention has the following advantages: 1. In this utility model, the postpartum woman holds the handrail and kneels on the kneeling pad of the sliding seat. The postpartum woman's lower limbs are brought together and close together. At the same time, the sliding rod moves inside the fixed cylinder, and the spring is compressed. The postpartum woman rotates the adjustment knob according to her own exercise needs, so that the adjustment knob moves on the fixed cylinder. One side of the adjustment knob abuts against one end of the spring, changing the degree of spring compression, and thus adjusting the constraint force of the damping component on both sides of the sliding seat in real time. The postpartum woman's legs move back and forth, compressing the spring, thereby exercising the postpartum woman's pelvic floor muscles. The entire adjustment process does not require manual loosening, moving or re-fixing of the components. The operation can be completed simply by rotating the knob. The steps are simple and time-saving. During the exercise, the postpartum woman can flexibly fine-tune the resistance according to her own muscle exertion.

[0013] 2. The kneeling pad is made of sponge, which has soft and cushioning properties and can reduce the direct pressure between the calf and the seat. The arc groove can conform to the curve of the mother's calf, achieving precise positioning and support of the leg, and avoiding soreness caused by leg slippage or uneven local pressure during exercise.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example: Adjustable resistance gynecological pelvic floor muscle exercise device, including main frame 1, as shown in the attached figure. Figure 1 As shown, the bottom of the main frame 1 has a support rod 12, and both ends of the support rod 12 have anti-slip feet 13. The anti-slip feet are made of plastic and are fitted onto the ends of the support rods. The anti-slip feet ensure the stability of the entire main frame. Symmetrically arranged smooth rods 2 are installed on the main frame 1, and a pair of sliding seats 3 are installed on the smooth rods 2, as shown in the attached diagram. Figure 4As shown, a kneeling pad 4 is installed on the sliding seat 3. The sliding seat 3 includes a seat body 15 mounted on the smooth rod 2. Main rollers 16 and auxiliary rollers 17 are installed around the seat body 15, and the main rollers 16 and auxiliary rollers 17 respectively fit against the upper and lower surfaces of the smooth rod 2. The kneeling pad 4 is mounted on the upper surface of the seat body 15. When the mother exercises, the leg force is uneven (such as one leg exerting more force), the sliding seat is prone to shifting left and right along the smooth rod, resulting in asynchronous movement of the two sliding seats. This not only affects the symmetry of pelvic floor muscle exercise, but may also cause the damping components (sliding rod and fixed cylinder) to bear lateral force, aggravating component wear or jamming. Therefore, the main roller and auxiliary roller are arranged vertically. The surfaces of the main roller and auxiliary roller are arc-shaped concave structures. The arc-shaped concave surfaces of the main roller and auxiliary roller are close to the smooth rod. The clamping effect of the two rollers on the smooth rod can limit the vertical and horizontal displacement of the sliding seat, ensuring that it always moves horizontally along the axis of the smooth rod, preventing the sliding seat from shifting or shaking during exercise, and ensuring the accuracy and continuity of the pelvic floor muscle exercise. The kneeling pad 4 includes a base plate 23 connected to the seat body 15. The base plate 23 has a sponge pad 24, and the sponge pad 24 has an arc-shaped groove 25 adapted to the calf of the mother. The kneeling pad is made of sponge, which has soft cushioning properties and can reduce the direct pressure between the calf and the seat body. The arc-shaped groove can conform to the curve of the calf of the mother, realize the precise positioning and support of the leg, and avoid soreness caused by leg slippage or uneven local force during exercise. The front of the main frame 1 has a handrail 5 with two grip positions, allowing the mother to choose the grip position according to her needs, thus improving the flexibility of the component. A damping element 6 is installed between the sliding seats 3 on both sides, as shown in the attached figure. Figure 2 As shown, the damping element 6 includes a fixed cylinder 7 connected to one side of the sliding seat 3 and a sliding rod 8 connected to the other side of the sliding seat 3, as shown in the attached figure. Figure 3As shown, the sliding rod 8 is embedded in the fixed cylinder 7; the fixed cylinder 7 has a threaded portion 9, on which an adjusting knob 10 is fitted. A spring 11 is fitted on the sliding rod 8 and the fixed cylinder 7. One end of the spring 11 abuts against the ring on the sliding rod 8, and the other end of the spring 11 abuts against one end of the adjusting knob 10. The sliding rod 8 includes a main rod 18, one end of which is embedded in the fixed cylinder 7, and the other end of which has an annular plate 19. One end of the spring 11 abuts against the annular plate 19. The diameter of the fixed cylinder is adapted to the inner diameter of the spring, and the diameter of the annular plate is larger than the outer diameter of the spring, so that the spring can be stably fitted on the fixed cylinder. The stable abutment between one end of the spring and the annular plate prevents the spring from skewing or getting stuck during compression or rebound, which would prevent the transmission of uniform damping force and directly affect the effectiveness of the resistance adjustment function. One side of the annular plate 19 has a connector 20 that connects to a sliding seat 3. The front of the sliding seat has a fixing plate with a stud. The connector is fitted onto the stud, and a nut is screwed onto the stud, thus connecting the sliding rod to the sliding seat. The fixing cylinder is connected to the sliding seat in the same way. The adjusting knob is threaded into the threaded part of the fixing cylinder. When the knob is rotated, it moves axially along the threaded part. When the knob moves towards the spring, it actively compresses the spring, causing it to deform pre-deform, increasing the initial resistance, requiring more effort for the mother to close her legs. When the knob moves away from the spring, the spring pre-compression decreases, reducing the initial resistance, making it easier for the mother to close her legs. The entire adjustment process requires no disassembly of any parts; it can be completed simply by rotating the knob. When compressed, the spring continuously applies axial thrust to the adjustment knob. The self-locking property of a simple threaded fit relies on thread friction. When the spring force is high (e.g., when the mother selects a high resistance level) or the threads wear after long-term use, the axial thrust may overcome the friction, causing the adjustment knob to slowly shift, resulting in resistance level drift and inability to maintain the set exercise intensity. To prevent instability of the adjustment knob, a locking nut is added. The locking nut engages with the threaded part. After determining the position of the adjustment knob, rotating the locking nut tightly against the knob creates a rigid constraint through mechanical pre-tightening, improving the knob's anti-loosening performance and ensuring the set resistance level remains stable. The main frame 1 has grip bars 14 at both ends for easy handholding by the mother. When the mother kneels on the kneeling mat, she can use the grip bars to move up and down for safety. The adjustment knob 10 includes a main ring 21 that engages with the threaded portion 9. The other end of the spring 11 abuts against the main ring 21. The outer side of the main ring 21 has a side support 22. This structure makes it easier for the mother to rotate the adjustment knob.

[0018] The working principle of this utility model is as follows: When a postpartum woman performs pelvic floor muscle exercises, she needs to actively control her lower limbs to close together. This forceful action causes the sliding seats 3 on both sides to move inward along the smooth rod 2. The damping element 6 connected to the sliding seat 3 moves in conjunction with this action. One side of the sliding seat 3 pulls the sliding rod 8, causing the sliding rod 8 to move axially within the fixed cylinder 7. When the sliding rod 8 moves, the annular plate 19 at its end compresses the spring 11, causing the spring 11 to further compress and deform. The spring 11 generates a reverse elastic force due to the deformation. This elastic force is transmitted through the annular plate 19 to the sliding rod 8, and then from the sliding rod 8 to the sliding seat 3, ultimately acting on the postpartum woman's legs. The postpartum woman needs to resist this elastic force to continuously complete the lower limb closing action. During the process, the pelvic floor muscles passively contract and exert force to achieve a targeted exercise effect. When the mother relaxes her lower limbs, the rebound force of the spring 11 pushes the sliding rod 8 back to its original position, which in turn drives the sliding seat 3 back to its initial position along the smooth rod 2, completing one exercise cycle. Depending on the mother's pelvic floor muscle strength level or exercise stage, the exercise resistance can be adjusted in real time by adjusting the knob 10. The main ring 21 of the adjusting knob 10 is threadedly engaged with the threaded part 9 of the fixed cylinder 7. When the adjusting knob 10 is rotated clockwise, the main ring 21 moves axially along the threaded part 9 toward the spring 11, actively squeezing the spring 11 and increasing the initial compression of the spring 11. At this time, the initial resistance that the mother needs to overcome when closing her lower limbs increases, and the exercise intensity is improved.
