Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pelvic floor muscle rehabilitation, and in particular to a biofeedback device for pelvic floor muscle rehabilitation training. Background Art
[0002] The pressure on the mother's pelvic floor muscles may increase as the fetus grows in the uterus (fetal weight increases), causing the pelvic floor muscles to maintain high tension for a long time in the late pregnancy, which makes them very prone to deformation. The muscle tension also decreases to a certain extent. Therefore, mothers often experience pelvic floor damage after delivery, and even female pelvic floor dysfunction (FPFD), causing female sexual dysfunction, pelvic organ prolapse and stress urinary incontinence, etc., seriously affecting the patient's quality of life and mental health.
[0003] However, the patients who undergo pelvic floor muscle rehabilitation training are mostly women who have just given birth. At this time, most women are relatively weak. It is difficult for them to complete pelvic floor muscle rehabilitation training movements such as opening or lifting the thighs on their own. Moreover, the quantity and quality of the movements are not up to standard, which has little effect on rehabilitation.
[0004] The two movements of opening the thighs or lifting the thighs are simple to perform separately, with a single effect and stimulating fewer parts of the pelvic floor muscles. Therefore, if these two sets of movements can be completed at the same time, not only can more parts of the pelvic floor muscles be stimulated to achieve better rehabilitation effects, but also the patient's exercise time can be reduced, giving the patient more time to rest. However, due to the patient's weak condition, it is difficult to complete them at the same time. Relying on equipment for auxiliary training is a feasible method, but the existing pelvic floor muscle rehabilitation training devices have a single function and can only swing left and right to drive the patient's legs to open and close movements, or move up and down to drive the patient's legs to lift legs. The two movements that can rehabilitate the patient can only be completed separately. When completing one and then doing the other, the patient's physical strength may not be able to keep up, which not only fails to achieve a good rehabilitation effect, but also easily causes other damage to the patient. However, the intensity of doing only one is insufficient and cannot meet the intensity requirements of rehabilitation. Summary of the Invention
[0005] The purpose of the present invention is to provide a biofeedback device for pelvic floor muscle rehabilitation training. The rotating plate rotates to drive the patient's thigh to open and close, while the supporting plate rises to drive the patient's thigh up, allowing the patient to complete the up and down movement of the thigh, completing two sets of exercises with different requirements at the same time, which not only achieves the required exercise intensity but also reduces the patient's exercise volume, thereby reducing the burden on the patient's body. "This solves the problem that most existing pelvic floor muscle rehabilitation training devices can only perform one of the following: opening the thigh or lifting the thigh. However, the intensity of performing only one of the two exercises is insufficient to meet the intensity requirements of rehabilitation. When completing one exercise and then performing the other, the patient's physical strength is likely to be insufficient, which not only fails to achieve a good rehabilitation effect but also easily causes other harm to the patient."

[0034] Also includes:
[0035] The arc groove 15 has the same radius as the radius of the fan-shaped rotation of the rotating plate 3, that is, the rotation of the rotating plate 3 and the arc groove 15 are on the same path. The bottom of the arc groove 15 is not flat and constant, but gradually deepens from the starting section to the end, forming a completely inclined route. For details, see Figure 5 ,and Figure 5 "In order to make viewing more direct, the cross-sectional view of the arc groove 15 is set to a horizontal cross-sectional view" so that the structure of the arc groove 15 is easier to understand;
[0036] The second lifting rod 10 is located at the top of the arc groove 15. The second lifting rod 10 can reciprocate in the up and down directions, and the bottom end of the second lifting rod 10 can extend to the inner cavity of the arc groove 15;
[0037] The first lifting rod 8 is symmetrically arranged with the second lifting rod 10 . The first lifting rod 8 can also perform reciprocating motion in the up and down directions, and the motion direction is opposite to that of the second lifting rod 10 .
[0038] An inner cavity of the base 1 is provided with an empty slot 30 , and an electric motor 31 is fixedly connected to the inner cavity of the empty slot 30 . The output end of the electric motor 31 is fixedly connected to the rotating rod 2 .

The second lifting rod 10 passes through the rotating plate 3 and the mounting groove 4. The surface of the second lifting rod 10 and the part located inside the mounting groove 4 are fixedly connected to the second rack 11, and the second rack 11 is engaged with one side of the gear 6. One side of the mounting groove 4 is fixedly connected to a limiting ring 7. The first lifting rod 8 passes through the rotating plate 3 and the mounting groove 4 and passes through the limiting ring 7. The surface of the first lifting rod 8 and the part located inside the mounting groove 4 are fixedly connected to the first rack 9, and the first rack 9 is engaged with the other side of the gear 6.
[0040] The second lifting rod 10 and the first lifting rod 8 are lifted and lowered by the gear 6, thereby achieving the operation of lifting the patient's thigh, that is, helping the patient to do the rehabilitation movement of lifting the legs up and down.
[0041] The second lifting rod 10 extends to one end of the bottom of the rotating plate 3 and is rotatably connected to a circular plate 12. Both sides of the circular plate 12 are fixedly connected to the limiting plates 14. The bottom of the circular plate 12 is rotatably connected to the rolling wheel 13.

The limiting grooves 16 are parallel to the downward angle of the circular arc groove 15, and the limiting grooves 16 are tilted downward together with the limiting grooves 16 on the other side. The inner cavities of the two groups of limiting grooves 16 are slidably connected to the surfaces of the two groups of limiting plates 14.
[0042] The second lifting rod 10 is moved along the inner cavity of the circular arc groove 15, and is affected by the limiting groove 16 and the limiting plate 14 at the same time. The second lifting rod 10 changes with the height change of the bottom of the circular arc groove 15, that is, as the rotating plate 3 rotates, the second lifting rod 10 moves downward more and more, and the second lifting rod 10 moves downward and drives the second rack 11 to move. The movement of the second rack 11 drives the gear 6 to rotate. The rotation of the gear 6 drives the first lifting rod 8 to rise. The rise of the first lifting rod 8 drives the support plate 19 to rise. The rise of the support plate 19 drives the patient's thigh to rise, so that the patient completes the up and down movement of the thigh and completes two sets of exercises with different requirements at the same time, which not only achieves the exercise intensity but also reduces the patient's exercise amount, thereby reducing the burden on the patient's body.

[0044] By rotating the semicircular plate 22 and the buckle 23, the patient's thigh is limited, avoiding the patient's thigh from accidentally slipping out during rehabilitation training, ensuring the safety of the patient when using the device. At the same time, the slide groove 25 and the slider 24 cooperate with each other to allow the support plate 19 to move up and down more smoothly while being limited, making it more stable.
[0045] A support rod 26 is fixedly connected to the top of the base 1 and located on one side of the arc groove 15. An auxiliary frame 27 is fixedly connected to the top of the support rod 26. An embedding groove 28 is provided on the surface of the auxiliary frame 27. A sliding rod 29 is fixedly connected to one side of the rotating plate 3. The sliding rod 29 passes through the embedding groove 28.
[0046] The slide bar 29 slides in the embedded groove 28 of the auxiliary frame 27, which can reinforce the rotating plate 3 and make the rotating plate 3 more secure during the rotation process. The auxiliary frame 27 can block and restrain the patient's calf to prevent the thigh from swinging the calf during the rotation process, thereby affecting rehabilitation training. The material of the bottom of the auxiliary frame 27 is rubber, which is soft and will not cause damage to the patient's calf.
[0047] Working principle: first place the patient's thigh on the support plate 19, when the motor 31 rotates, drives the rotating rod 2 to rotate, the rotating rod 2 rotates and drives the rotating plate 3 to rotate, the rotating plate 3 rotates and drives the patient's thigh to open and close, and performs rehabilitation training for the patient, the rotating plate 3 rotates and drives the second lifting rod 10 to move, and the second lifting rod 10 moves in the inner cavity of the arc groove 15, while moving, it is affected by the limit groove 16 and the limit plate 14, and the second lifting rod 10 changes with the height change of the bottom of the arc groove 15, that is, as the rotating plate 3 rotates, the second lifting rod 10 moves more and more downward, the second lifting rod 10 moves downward and drives the second rack 11 to move, the second rack 11 moves and drives the gear 6 to rotate, the gear 6 rotates and drives the first lifting rod 8 to rise, the first lifting rod 8 rises and drives the support plate 19 to rise, and the support plate 19 rises and drives the patient's thigh to rise, so that the patient completes the up and down movement of the thigh and completes two sets of exercises with different requirements at the same time.
[0048] Example 2
[0049] In order to make the pelvic floor muscle rehabilitation training device better serve patients, a biofeedback device adapted to the pelvic floor muscle rehabilitation training device is specially set up. The biofeedback device has structures such as sensors and display screens:
[0050] Pressure sensors are embedded on the contact surface of the support plate 19 and the inner side of the semicircular baffle 20 to monitor in real time the contraction pressure changes of the pelvic floor muscles during thigh exercise. The sensor signal is fed back via wires to the control module integrated into the side wall of the base 1. After processing, it is synchronously displayed on the touch screen on the top of the auxiliary frame 27 (not shown). The display screen intuitively presents the muscle contraction intensity and duration with a dynamic curve and a percentage progress bar, and sets a target threshold, such as the green area, as the effective training range. When the patient completes the leg lift, the height of the first lifting rod 8 is converted into an electrical signal through the meshing relationship between the gear 6, the first rack 9, and the first and second racks 11. This signal is then superimposed and analyzed with the sensor data to form real-time feedback. If insufficient pelvic floor muscle force is detected, the system can automatically adjust the speed of the motor 31 and reduce the opening and closing amplitude of the rotating plate 3 to adapt the movement intensity to the patient's current muscle strength level. Conversely, if the force is met, the screen prompts an audio encouragement and records the single training data for follow-up evaluation. This closed-loop design not only ensures precise correspondence between movements and muscle activation, but also enhances patients' sense of control over their rehabilitation process through visual data.
