Description

Technical Field

[0001] This invention relates to the field of postpartum care technology, specifically to a postpartum pelvic floor muscle contraction rehabilitation device and method. Background Technology

[0002] The pelvic floor muscles are the group of muscles that close the bottom of the pelvis. This muscle group acts like a "net," tightly supporting organs such as the urethra, bladder, vagina, uterus, and rectum, thus maintaining their normal position and enabling them to function. After childbirth, the pelvic floor muscles and fascia may lose elasticity due to expansion, and often some muscle fibers may rupture. If muscle fibers rupture, corresponding functional disorders may occur, such as urinary and fecal incontinence and pelvic organ prolapse. However, if postpartum women persist with rehabilitation exercises, the pelvic floor muscles can recover to near their pre-pregnancy state. Therefore, a postpartum pelvic floor muscle contraction rehabilitation device is needed for recovery exercises.

[0003] Existing postpartum pelvic floor muscle contraction rehabilitation training equipment generally uses automated devices to support the buttocks of postpartum women, in order to help the pelvic floor muscle groups recover to their initial state, thereby achieving the effects of exercise and guidance and improving the quality of treatment.

[0004] However, in actual use, the automated equipment is often too rigid when it comes into contact with the patient's body. Postpartum women are relatively fragile, and the pushing process of the electric equipment requires a considerable amount of time for the patient to adapt. While it can effectively achieve the exercise effect, it can also damage the patient's pelvic floor muscles and affect the patient's rehabilitation progress. In view of this, we propose a postpartum pelvic floor muscle contraction rehabilitation device and method. Summary of the Invention

[0005] The purpose of this invention is to provide a postpartum pelvic floor muscle contraction rehabilitation device and method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a postpartum pelvic floor muscle contraction rehabilitation device, comprising a body, a headrest fixedly installed on the upper surface of the body, a placement groove formed at the center of the body, a positioning roller rotatably mounted on the inner surface of the placement groove, one end of a tensioning strap fixedly connected to the arc-shaped outer wall of the positioning roller, a guide roller rotatably mounted on the inner surface of the placement groove, a take-up roller rotatably mounted on the inner surface of the placement groove, and a massage component disposed inside the placement groove, the massage component comprising:

[0007] A forward and reverse motor is fixedly installed on the inner wall of the mounting slot. The output end of the forward and reverse motor is fixedly connected to the end of a threaded rod, and a threaded transmission block is threadedly connected to the outer wall of the threaded rod.

[0008] A connecting block is fixedly installed on the top of the threaded transmission block, a supporting block is movably connected to the side wall of the connecting block, a guide seat is fixedly installed on the inner wall of the placement groove, and a guide groove is opened on the upper surface of the guide seat.

[0009] A massage ball is provided on the upper surface of the tension band;

[0010] A connecting shaft is provided, which passes through the center of the take-up roller and is fixedly connected to the take-up roller. A worm gear is rotatably mounted on the inner wall of the machine body, and the end of a worm spring is fixedly mounted on the outer wall of the worm gear near the center of the machine body.

[0011] Preferably, the width of the tension band is adapted to the width of the placement groove, so that the tension band can completely cover the placement groove, providing a better massage effect for the patient while also preventing other debris from falling into the placement groove.

[0012] Preferably, the number of guide seats is provided in two sets, and the two sets of guide seats are symmetrically arranged on the inner surfaces of the left and right sides of the placement groove with the central axis of the placement groove as the axis of symmetry, so as to ensure the movement direction and movement state of the lifting block.

[0013] Preferably, the massage ball is made of rubber and there are several groups of massage balls. The groups of massage balls are evenly distributed on the upper surface of the tension band, so as to provide a massage experience for the patient's back when the tension band is in motion.

[0014] Preferably, a circular through hole with a diameter larger than the outer diameter of the connecting shaft is provided at the center of the worm gear disk, and the connecting shaft passes through the circular through hole so that there is no mutual interference between the worm gear disk and the connecting shaft.

[0015] Preferably, a rotary knob is rotatably mounted on the bottom outer wall of the machine body, and the upper surface of the rotary knob is fixedly connected to the end of a worm gear.

[0016] Preferably, the machine body is provided with a striking component, which includes a driving gear. The driving gear is coaxially fixedly mounted on the guide roller. A transmission gear is rotatably mounted on the inner wall of the machine body. A rotating rod is rotatably mounted on the inner wall of the machine body. A driven gear passes through the rotating rod and is fixedly connected to the rotating rod. A striking piece is fixedly mounted on the arc-shaped outer wall of the rotating rod, and bristles are provided on the arc-shaped outer wall of the rotating rod.

[0017] Preferably, the length of the striking piece is slightly longer than the distance between the arc-shaped outer wall of the rotating rod and the tension band, so that the striking piece will strike the tension band when the rotating rod is rotated.

[0018] This invention also provides a postpartum pelvic floor muscle contraction rehabilitation method, comprising the following steps:

[0019] S1. The patient lies on the body with their head resting on a headrest and their buttocks on a taut strap.

[0020] S2. After the patient is fully lying down and ready, start the forward and reverse motors so that the lifting block moves upward along the guide groove, thereby causing the tension band to bend towards the center of the body to perform restorative exercises on the muscle groups in the patient's pelvis.

[0021] S3. After exercising for a period of time, first turn off the forward and reverse motors, wait for the equipment to stop, and then the patient gets up to end the exercise.

[0022] Compared with the prior art, the present invention provides a postpartum pelvic floor muscle contraction rehabilitation device and method, which has the following beneficial effects:

[0023] 1. The postpartum pelvic floor muscle contraction rehabilitation device and method, in order to reduce the pain of patients during rehabilitation training, is equipped with a massage component. With the stretching and contraction of the spiral spring, the winding roller can drive the tension belt to massage the massage ball on the patient's back and waist during the lifting and lowering process, soothing the patient's body, reducing the patient's pain, effectively helping the patient adapt to the rhythm of rehabilitation training, and improving the exercise effect of the device.

[0024] 2. In order to ensure the tension of the worm coil spring on the connecting shaft, and thus ensure the tautness of the tension band maintained by the winding roller, the tension of the worm coil spring is increased by rotating the rotary knob, thereby increasing the service life of the worm coil spring and ensuring the effectiveness of the device.

[0025] 3. The postpartum pelvic floor muscle contraction rehabilitation device and method, in order to better improve the massage and relief effect of the tension band and massage ball on the patient's back, is equipped with a tapping component, which, together with the transmission of the active gear, transmission gear and driven gear, allows the rotating rod to drive the striking plate to continuously strike the tension band, so that it vibrates to a certain extent, thereby improving the massage effect of the tension band and the massage ball on its surface on the patient's back.

[0030] like Figure 1-3 As shown, the present invention provides a technical solution: a postpartum pelvic floor muscle contraction rehabilitation device and method, comprising a body 1, a headrest 2 fixedly installed on the upper surface of the body 1, a placement groove formed at the center of the body 1, a positioning roller 3 rotatably installed on the inner surface of the placement groove, a tensioning band 4 fixedly connected to the arc-shaped outer wall of the positioning roller 3, a guide roller 5 rotatably installed on the inner surface of the placement groove, a winding roller 6 rotatably installed on the inner surface of the placement groove, a massage component provided inside the placement groove, the massage component including a forward and reverse motor 7, the forward and reverse motor 7 fixedly installed on the inner wall of the placement groove, the output end of the forward and reverse motor 7 fixedly connected to the end of a threaded rod 8, the threaded rod... A threaded drive block 9 is threadedly connected to the outer wall of the machine body 8. A connecting block 10 is fixedly installed on the top of the threaded drive block 9. A lifting block 11 is movably connected to the side wall of the connecting block 10. A guide seat 12 is fixedly installed on the inner wall of the placement groove. A guide groove 13 is opened on the upper surface of the guide seat 12. A massage ball 14 is provided on the upper surface of the tensioning belt 4. A connecting shaft 15 passes through the shaft center of the take-up roller 6 and is fixedly connected to the take-up roller 6. A worm gear disk 18 is rotatably installed on the inner wall of the machine body 1. The end of a worm spring 19 is fixedly installed on the outer wall of the worm gear disk 18 near the center of the machine body 1. The other end of the worm spring 19 is fixedly connected to the arc-shaped outer wall of the connecting shaft 15.

[0031] In one embodiment of the present invention, the placement groove is located at the center of the body 1, and both the headrest 2 and the placement groove are located on the central axis of the body 1. This allows the patient's head to rest on the headrest 2 and their buttocks to rest on the tension band 4 in the placement groove when lying on the upper surface of the body 1. In addition, the width of the tension band 4 is adapted to the width of the placement groove, so that the tension band 4 can completely cover the placement groove, providing a better massage effect for the patient and preventing other debris from falling into the placement groove and adversely affecting the normal use of the device. At the same time, the positioning roller 3 and the guide roller 5 are respectively located on the top of the left and right sides of the placement groove, and the top of the positioning roller 3 and the guide roller 5 are flush with the upper surface of the body 1 to avoid excessive gaps between the tension band 4 and the body 1, which could cause injury to the patient. In addition, the take-up roller 6 is located directly below the guide roller 5, closer to the center of the placement groove, to increase the contact area between the tension band 4 and the guide roller 5, thereby effectively improving the transmission effect of the tension band 4 on the guide roller 5.

[0032] In an embodiment of the present invention, the lower surface of the threaded transmission block 9 is slidably connected to the inner wall of the bottom of the mounting groove, so that the movement of the threaded transmission block 9 is somewhat restricted. Specifically, when the forward and reverse motor 7 is started, in conjunction with the rotation of the threaded rod 8, the threaded transmission block 9 moves horizontally along the inner surface of the bottom of the mounting groove, but does not rotate with the rotation of the threaded rod 8. At the same time, the lifting block 11 is slidably connected to the side wall of the connecting block 10 through a rotatable shaft, so that the lifting block 11 can slide vertically along the side wall of the connecting block 10 and also rotate. In addition, two sets of guide seats 12 are provided, and the two sets of guide seats 12 are symmetrically arranged on the inner surfaces of the left and right sides of the mounting groove with the central axis of the mounting groove as the axis of symmetry. At the same time, the guide groove 13 is inclined on the upper surface of the guide seat 12 near the central axis of the mounting groove, so that when the lifting block 11 slides along the guide groove 13, it will also deflect towards the center of the mounting groove as its height increases. Firstly, the massage balls 14 are made of rubber spheres, and several groups of massage balls 14 are evenly distributed on the upper surface of the tension band 4, so as to provide a massage experience for the patient's back when the tension band 4 moves. At the same time, a circular through hole with a diameter larger than the outer diameter of the connecting shaft 15 is opened at the axis of the worm gear 18, and the connecting shaft 15 passes through the circular through hole, so that there is no mutual interference between the worm gear 18 and the connecting shaft 15, thereby ensuring the relative stability of the device during operation. In addition, the worm coil spring 19 is sleeved on the arc-shaped outer wall of the connecting shaft 15, so that the connecting shaft 15 can obtain a more stable transmission effect. Furthermore, in the initial state (when the tension band 4 is in a straight state and the upper surface of the machine body 1 is parallel), the worm coil spring 19 has a certain winding tendency, that is, the winding roller 6 is still in a winding state of the tension band 4, so that the tension band 4 can always be kept taut, avoiding gaps between the tension band 4 and the placement groove, which could cause pinching injury to the patient's back.

[0033] In addition, to ensure the tension of the worm spring 19 on the connecting shaft 15, and thus the effect of the take-up roller 6 in maintaining the tension of the tension belt 4, a rotary knob 16 is rotatably installed on the bottom outer wall of the machine body 1. The upper surface of the rotary knob 16 is fixedly connected to the end of the worm 17. Specifically, the worm 17 meshes with the worm wheel 18 to achieve transmission. Specifically, by rotating the rotary knob 16, in conjunction with the worm 17, the worm wheel 18 can rotate. When the worm spring 19 is stretched and contracted for a long time and cannot maintain the tension of the tension belt 4 in the initial state, the tension of the worm spring 19 can be increased by rotating the rotary knob 16, thereby increasing the service life of the worm spring 19 and ensuring the effectiveness of the device.

[0034] Meanwhile, in order to better improve the massage and soothing effect of the tension band 4 and massage ball 14 on the patient's back, the body 1 is equipped with a tapping component. The tapping component includes a drive gear 20, a guide roller 5 is coaxially fixedly installed with the drive gear 20, a transmission gear 21 is rotatably installed on the inner wall of the body 1, a rotating rod 23 is rotatably installed on the inner wall of the body 1, a driven gear 22 passes through the rotating rod 23 and is fixedly connected to the rotating rod 23, a striking plate 24 is fixedly installed on the arc-shaped outer wall of the rotating rod 23, and bristles 25 are provided on the arc-shaped outer wall of the rotating rod 23.

[0035] In an embodiment of the present invention, one side of the transmission gear 21 meshes with the driving gear 20 to achieve transmission, while the other side of the transmission gear 21 meshes with the driven gear 22 to achieve transmission. This allows the guide roller 5 to rotate under the influence of the tension belt 4, and in conjunction with the driving gear 20 and the transmission gear 21, the driven gear 22 drives the rotating rod 23 to rotate. In addition, the length of the striking piece 24 is slightly longer than the distance between the arc-shaped outer wall of the rotating rod 23 and the tension belt 4, so that when the rotating rod 23 rotates, the striking piece 24 will strike the tension belt 4 to cause it to vibrate. This improves the massage effect of the tension belt 4 and the massage balls 14 on its upper surface on the patient's back. Furthermore, as the rotating rod 23 rotates continuously, the bristles 25 can clean the upper surface of the tension belt 4, preventing dust or debris from the patient from contaminating the upper surface of the tension belt 4 and affecting the subsequent normal use of the device.

[0036] In this invention, during use, the patient lies on the machine body 1 with their head placed on the headrest 2 and their buttocks on the upper surface of the tension belt 4. The forward and reverse motor 7 is then activated, causing the threaded transmission block 9 to reciprocate horizontally along the bottom inner surface of the placement groove under the drive of the threaded rod 8. This, in conjunction with the guide seat 12 and guide groove 13, allows the lifting block 11 to deflect towards the central axis of the machine body 1 as it rises. This, combined with the tension belt 4, lifts the patient's pelvis while simultaneously pushing it towards the center, aiding in the rehabilitation of the patient's pelvic floor muscles and improving the effectiveness of rehabilitation training.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
