Description

Technical Field

[0001] The present application relates to the technical field of electromyoelectric stimulation therapeutic apparatus, and in particular to a pelvic floor muscle electromyoelectric stimulation rehabilitation therapeutic apparatus. Background Art

[0002] Pelvic floor muscle electromyostimulation therapy is a physical therapy method for female pelvic floor muscle dysfunction. It is mainly used to improve postpartum pelvic floor muscle relaxation, urinary incontinence, pelvic organ prolapse and other problems. Pelvic floor muscle electromyostimulation therapy is based on Faraday's law of electromagnetic induction. It penetrates deep into the tissue through magnetic pulses, activates nerve pulses, and causes pelvic floor muscle contraction. This electrical stimulation can promote passive muscle contraction, increase muscle strength and intensity, and thus improve the function of the pelvic floor muscles.

[0003] Existing pelvic floor muscle electromyography stimulation rehabilitation treatment equipment mainly includes a display main body system and an electrode probe (vaginal electrode). When using the instrument for treatment, the power cord of the electrode probe needs to be connected to the display main body system to connect the display main body system and the electrode probe. However, since the power cord of the electrode probe is relatively long, after the electrode probe is placed in the human body, the power cord is dragged on the outside of the electrode probe. The power cord has a large gravity. The gravity of the power cord will pull the electrode probe out of the human body, affecting the position where the electrode probe generates pulses, thereby affecting the treatment effect on the pelvic floor muscles.

[0022] See also Figure 2 and Figure 3 The electrode probe body 1 is provided with a winding device for storing the power cord 5, and the winding device includes a support shaft 401, a coil spring 402, a sleeve 403, a baffle 404 and a guide wheel 405. The axis of the support shaft 401 is in the same straight line as the axis of the support shell 101. One end of the support shaft 401 is fixedly inserted into the limit plate 2 and the hand-held part 3, and the other end of the support shaft 401 is in the support shell 101. The support shaft 401 in the support shell 101 is provided with a movable sleeve of the coil spring 402, one end of the coil spring 402 is fixedly connected to the support shaft 401, and the outer sleeve of the coil spring 402 is provided with a sleeve 403. The inner wall of the sleeve 403 is connected to the coil spring 40 2, baffles 404 are provided at both ends of the shaft sleeve 403, and the baffles 404 are used to prevent the power cord 5 from falling off the shaft sleeve 403. A mounting shaft is fixedly connected to one side of the electrode probe body 1, and a guide wheel 405 is provided on the movable sleeve of the mounting shaft. The guide wheel 405 is used to provide steering for the power cord 5. A rotating joint is provided on the top fixed sleeve of the shaft sleeve 403, and the outer ring of the rotating joint is electrically connected to the electrode sheet 103, and the inner ring of the rotating joint is electrically connected to one end of the power cord 5.

[0023] See also Figure 2-Figure 4, a limiting device for limiting the rotation of the winding device is provided on the connecting hole 201, the limiting device includes a mounting groove 701, an electromagnetic ring 702, a reset spring 703, a permanent magnet ring 704 and a limiting column 705, a mounting groove 701 penetrating the limiting plate 2 is opened on the limiting plate 2, an electromagnetic ring 702 is fixedly installed at the bottom end of the mounting groove 701, a reset spring 703 is fixedly connected to the electromagnetic ring 702, a permanent magnet ring 704 is fixedly connected to the other end of the reset spring 703, and the permanent magnet ring 704 is slidingly sealed in the mounting groove 701, the permanent magnet ring 704 can only slide in the axial direction of the mounting groove 701 and cannot rotate relatively, and a plurality of limiting columns 705 are provided in an annular array on the upper end surface of the permanent magnet ring 704; a control switch 301 is fixedly installed on the side wall of the hand-held part 3, and the control switch 301 is electrically connected to the electromagnetic ring 702; a plurality of fixing grooves 406 are provided in an annular array on the end surface of the baffle 404 facing the permanent magnet ring 704.

[0024] When the electromagnetic ring 702 is energized, it generates a magnetic force that repels the permanent magnetic ring 704. When the electromagnetic ring 702 is energized, the electromagnetic ring 702 can push the permanent magnetic ring 704 and the limit post 705 to move toward the baffle 404, so that the limit post 705 is inserted into the fixing groove 406 and fixed with the baffle 404.

[0025] The number of the fixing grooves 406 is the same as the number of the limiting posts 705. When the electromagnetic ring 702 pushes the permanent magnetic ring 704 and the limiting posts 705 to move toward the baffle 404, the limiting posts 705 can be inserted into the fixing grooves 406.

[0026] The working principle of the first embodiment of the present invention is as follows: See also Figure 1-Figure 4 When using the pelvic floor muscle electromyography stimulation rehabilitation treatment device, it is necessary to first place the electrode probe into the position of 4 cm in the vagina. At this time, the connector 6 at the lower end can be pulled as needed, so that the connector 6 drives the power cord 5, and the power cord 5 in the electrode probe body 1 is pulled out. When the required length is reached, the connector 6 can be connected to the display main body system (existing equipment, not shown in the figure). At this time, the length of the power cord 5 outside the electrode probe body 1 is only the required length, and the power cord 5 outside the electrode probe body 1 will not be too long. During treatment, the gravity of the power cord 5 will not act on the electrode probe body 1 due to the presence of more power cords 5 outside the electrode probe body 1, resulting in the phenomenon that the electrode probe body 1 is pulled out of the vagina by the gravity of the power cord 5, thereby avoiding the problem of poor treatment effect caused by the change of the position of the electrode probe body 1; Furthermore, when the power cord 5 is pulled out to a required length, the connector 6 is electrically connected to the display main body system. At this time, by pressing the control switch 301, the electromagnetic ring 702 is connected to the current, and the electromagnetic ring 702 generates a magnetic force that repels the permanent magnet ring 704. At this time, the electromagnetic ring 702 pushes the permanent magnet ring 704 and the limit column 705 to move toward the baffle 404 until the limit column 705 is inserted into the fixing groove 406 of the baffle 404, so that the permanent magnet ring 704 and the limit column 705 fix the baffle 404 to prevent the baffle 404 and its connecting structure from continuing to rotate, thereby designing the length of the power cord 5 extending out of the support shell 101 to be fixed.

[0027] Embodiment 2 Since each person's physical condition is different, when the electrode probe is placed in the vagina, the electrode sheet 103 on the electrode probe may not be able to contact the pelvic floor muscles. In this case, the stimulation of the electrode sheet 103 of the electrode probe cannot effectively act on the pelvic floor muscles, thereby affecting the treatment effect on the pelvic floor muscles. Embodiment 2 is a further improvement on Embodiment 1.

[0028] The difference from the first embodiment is that, please refer to Figure 2 , Figure 5 and Figure 6 , the outer movable sleeve of the supporting shell 101 is provided with a flexible sleeve 102, the flexible sleeve 102 is tightly attached to the outer wall of the supporting shell 101, and the connection between the supporting shell 101 and the flexible sleeve 102 is sealed and installed, and the electrode sheet 103 is symmetrically embedded in the outer side of the flexible sleeve 102; the top of the inner wall of the supporting shell 101 is fixedly installed with an air replenishing device for inflating between the supporting shell 101 and the flexible sleeve 102, and the air replenishing device includes a fixed column 801, a threaded column 802, a slider 803, an outer cylinder 804, a vent 805, a pressure relief valve 806, a connecting pipe 807 and a one-way valve 808, the fixed column 801 is fixedly connected to the top of the shaft sleeve 403, and an internal thread is opened at the axial center position of the fixed column 801, and a threaded column 802 is threadedly connected to the internal thread of the fixed column 801, and the threaded column 802 is lower The outer cylinder 804 is fixedly mounted on the top of the inner wall of the supporting shell 101, and the sliding block 803 is slidingly sealed in the outer cylinder 804. Guide columns are fixedly mounted on both sides of the outer cylinder 804 to prevent the sliding block 803 from rotating. A vent hole 805 connecting the outer cylinder 804 with the supporting shell 101 and the flexible sleeve 102 is provided at the top of the outer cylinder 804. A pressure relief valve 806 is fixedly mounted on the bottom end of the side wall of the outer cylinder 804. A connecting pipe 807 for connecting the outer cylinder 804 with the supporting shell 101 and the flexible sleeve 102 is fixedly connected to the pressure relief valve 806. A one-way valve 808 is fixedly mounted on the sliding block 803 to connect the inner part of the outer cylinder 804 at the upper and lower ends of the sliding block 803.

[0029] The flow direction of the pressure relief valve 806 is from the connecting pipe 807 to the outer cylinder 804; the flow direction of the one-way valve 808 is from the outer cylinder 804 at the lower end of the slider 803 to the outer cylinder 804 at the upper end of the slider 803. When the flexible sleeve 102 is subjected to external pressure, the pressure on the flexible sleeve 102 reaches a certain value, and the gas between the support shell 101 and the flexible sleeve 102 will flow into the outer cylinder 804 below the slider 803 through the connecting pipe 807 and the pressure relief valve 806; and when the slider 803 slides toward the lower end of the outer cylinder 804, the gas at the lower end of the outer cylinder 804 will return to the outer cylinder 804 at the upper end of the slider 803 through the one-way valve 808.

[0030] The working principle of the second embodiment of the present invention is as follows: See also Figure 1-Figure 6 After the electrode probe is placed in the vagina, the connector 6 is pulled to electrically connect the connector 6 to the display main body system. In the process of pulling the connector 6, the connector 6 drives the power cord 5, so that the power cord 5 drives the shaft sleeve 403 to rotate. In this process, the shaft sleeve 403 drives the fixed column 801 to rotate. Since the slider 803 and the threaded column 802 are restricted by the guide column in the outer tube 804 and cannot rotate, at this time, the rotating fixed column 801 will rotate relative to the threaded column 802. Through the action of the external thread of the threaded column 802 and the internal thread of the fixed column 801, the threaded column 802 drives the slider 803 to move upward, so that the slider 803 squeezes the gas in the outer tube 804, and the gas in the outer tube 804 enters between the support shell 101 and the flexible sleeve 102 through the vent 805, and the flexible sleeve 102 expands, so that the flexible sleeve 102 and the electrode sheet 103 on the flexible sleeve 102 are close to the human body, preventing the electrode sheet 103 from not being able to be close to the human body and causing the pulse to fail to achieve the desired stimulation effect; Furthermore, when the flexible sleeve 102 is squeezed by a certain pressure of the human body, the gas pressure inside the flexible sleeve 102 increases, so that the gas in the flexible sleeve 102 can flow from the connecting pipe 807 and the pressure relief valve 806 into the outer tube 804 at the lower end of the slider 803, thereby preventing the pressure in the flexible sleeve 102 from being too high, causing the flexible sleeve 102 to squeeze the human body too much and causing discomfort to the human body.

[0031] Embodiment 3 During treatment, since the electrode probe needs to be placed in the vagina at a position of about 4 cm as the best position, during the treatment process, when the electrode sheet 103 of the electrode probe stimulates the pelvic floor muscles, the contraction of the pelvic floor muscles will cause the electrode probe to move to a certain extent. After the electrode probe moves, it will slip out, or the electrode sheet 103 of the electrode probe will be misaligned with the pelvic floor muscles to a certain extent, resulting in the electrode sheet 103 of the electrode probe The stimulation of the pelvic floor muscles becomes weaker. Embodiment 3 is a further improvement on Embodiment 2.

[0032] The difference from the second embodiment is that please refer to Figure 5 and Figure 7 A plurality of fixed suction cups 9 are equidistantly arranged on both sides of the limiting plate 2 , and a connecting hole 201 connecting the fixed suction cup 9 and the mounting groove 701 is opened in the limiting plate 2 .

[0033] The working principle of the third embodiment of the present invention is as follows: See also Figure 1-Figure 7 After the electrode probe is placed in the vagina, the connector 6 is pulled to electrically connect the connector 6 to the display main system, and then the control switch 301 is pressed to turn on the current in the electromagnetic ring 702, and the electromagnetic ring 702 pushes the permanent magnetic ring 704 and the limit column 705 to move toward the baffle 404, and fixes the baffle 404 and its connection structure. In the process of the permanent magnetic ring 704 moving toward the baffle 404, a negative pressure is generated between the permanent magnetic ring 704 and the electromagnetic ring 702, and the negative pressure is transmitted to the fixed suction cup 9 through the connecting hole 201, so that the fixed suction cup 9 adsorbs the human skin, thereby fixing the electrode probe to prevent the electrode sheet 103 of the electrode probe from being squeezed out of the human body due to the contraction of the pelvic floor muscles when the electrode sheet 103 of the electrode probe stimulates the pelvic floor muscles.
