TECHNICAL FIELD

[0001] The present application relates to the technical field of pelvic floor electrical stimulator, and particularly relates to a portable pelvic floor electrical stimulator and a use method thereof. BACKGROUND

[0002] The incidence of pelvic floor dysfunction is high, especially in patients with anorectal surgery, 50% of whom have different degrees of anal overflow, defecation difficulty, fecal incontinence, rectal prolapse and other problems. These problems seriously endanger the physical and mental health of patients. Pelvic floor electrical stimulation biofeedback is the main non-surgical treatment for anorectal functional disorders, which has been recommended in many foreign guidelines. Through biofeedback electrical stimulation treatment, the subtle pelvic floor muscle biological signals can be converted into visual and auditory signals to feedback to the patient, guiding the patient to gradually restore the functional state of the pelvic floor muscles through scientific training. The development history of portable pelvic floor magnetic field stimulator as an important device for the auxiliary treatment of pelvic floor dysfunction can be traced back to the end of the 20th century. Initially, the device was mainly used in the field of clinical medicine, stimulating the pelvic floor muscles through electromagnetic fields to help patients improve pelvic floor muscle strength.

[0003] In the prior art, the portable pelvic floor stimulator generally has the characteristics of light weight and small size. When used by patients with large body types or the elderly, patients with large body types may cause the device to sway and tilt due to poor center of gravity, and the elderly may have difficulty maintaining a fixed posture due to decreased muscle strength, joint stiffness or weakened balance, leading to device tilting. Tilting may cause the electrode position to shift, stimulating non-target areas and causing discomfort or pain in patients. Therefore, a portable pelvic floor electrical stimulator and a use method thereof are needed. SUMMARY

[0004] The purpose of the present application is to solve the shortcomings in the prior art that portable pelvic floor stimulators generally have the characteristics of light weight and small size, and when used by patients with large body types or the elderly, patients with large body types may cause the device to sway and tilt due to poor center of gravity, and the elderly may have difficulty maintaining a fixed posture due to decreased muscle strength, joint stiffness or weakened balance, leading to device tilting. Tilting may cause the electrode position to shift, stimulating non-target areas and causing discomfort or pain in patients. Therefore, a portable pelvic floor electrical stimulator and a use method thereof are needed.

[0005] To achieve the above purpose, the present application adopts the following technical solutions: A portable pelvic floor electrical stimulator includes a portable protective case and a side panel. A support linkage mechanism is provided on the outside of the side panel. The support linkage mechanism includes a drive motor located outside the side panel. A transmission rod is provided at the output end of the drive motor. A gear is fixedly connected to the side of the transmission rod away from the drive motor. A rack plate is meshed with the side of the gear. A pelvic floor electrical stimulator assembly is fixedly connected to the side of the rack plate away from the gear. A first bevel gear is driven and connected below the transmission rod. A second bevel gear is meshed with the side of the first bevel gear. A threaded rod is fixedly connected above the second bevel gear. The threaded rod is threaded on the side away from the second bevel gear. A connecting plate is connected, and a frame plate is fixedly connected to the side of the connecting plate. A suction cup support rod is fixedly connected to the bottom of the frame plate. Multiple sets of suction cup support rods are arranged linearly and evenly. The drive motor drives the gear to rotate through the transmission rod. The gear drives the pelvic floor electrical stimulator assembly to rise through the rack plate. The transmission rod drives the second bevel gear to rotate through the first bevel gear. The second bevel gear drives the connecting plate to descend through the threaded rod. The connecting plate drives the multiple sets of suction cup support rods to descend through the frame plate. When the pelvic floor electrical stimulator assembly rises for use, it drives the multiple sets of suction cup support rods to provide multi-point support to ensure the stability of the device and prevent tilting.

[0006] The suction cup support rod consists of a load-bearing rod and a suction cup, and the suction cup and the load-bearing rod are rotatably connected to each other, making it suitable for different ground surfaces.

[0007] The above technical solution further includes: The portable protective case is fixedly connected to the side panel. A rack and pinion drive belt is connected to the lower part of the drive rod. The rack and pinion drive belt is fixedly connected to the first bevel gear. The connecting plate is slidably connected to the portable protective case. The threaded rod is rotatably connected to the portable protective case. The suction cup support rod is inclined below the frame plate.

[0008] The portable protective case is rotatably connected to a spring-loaded door on the side near the suction cup support rod.

[0009] The rack and pinion drive belt is rotatably connected to a support plate, and the support plate is fixedly connected to the portable protective case.

[0010] A grooved plate is fixedly connected to the side of the pelvic floor electrical stimulator assembly away from the rack plate. The grooved plate is fixedly connected to the portable protective case, and the grooved plate is slidably connected to the frame plate.

[0011] An airbag assembly is disposed above the pelvic floor electrical stimulator assembly, and an electrode pad assembly is disposed on the side of the pelvic floor electrical stimulator assembly near the airbag assembly.

[0012] The portable protective case is rotatably connected to the top of a cover plate, and a handle is fixedly connected to the top of the cover plate.

[0013] The cover plate is rotatably connected to a buckle on the side away from the handle, the portable protective case is provided with a corresponding slot on the side near the buckle, and the portable protective case is provided with an operation display screen on the side near the buckle.

[0014] The control display screen can control the internal components of the device and display the instrument's operating status and various information.

[0015] A telescopic support rod is fixedly connected to the lower part of the pelvic floor electrical stimulator assembly, and the telescopic support rod is fixedly connected to the portable protective case.

[0016] A method for using a portable pelvic floor electrical stimulator includes the following steps: Step 1: When the patient needs to use the device, the support linkage mechanism on the outside of the side plate is activated, and the drive motor in the support linkage mechanism starts to run. When the drive motor runs, it controls the transmission rod to rotate. Step 2: When the transmission rod rotates, it drives the gear to rotate. The gear drives the rack plate to rise through the meshing connection. When the rack plate rises, it drives the pelvic floor electrical stimulator assembly to rise outside the portable protective case for the patient to use. Step 3: As the transmission rod rotates, it drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate through a meshing connection. The second bevel gear drives the threaded rod above to rotate. The threaded rod drives the connecting plate to descend through a threaded connection with the connecting plate. The connecting plate drives the frame plate to descend. The frame plate drives multiple sets of suction cup support rods to descend, and the multiple sets of suction cup support rods extend outward from the portable protective case. Step 4: As the pelvic floor electrical stimulator assembly rises, multiple sets of suction cup support rods simultaneously descend, providing stable support for the device from multiple points and preventing the device from tilting.

[0017] The present invention has the following beneficial effects: 1. In this invention, the drive motor drives the transmission rod to rotate, which in turn causes the gear to engage with the rack plate, thereby achieving a smooth rise of the pelvic floor electrical stimulation device assembly. At the same time, the transmission rod also drives the threaded rod to rotate through the bevel gear transmission system, which drives the connecting plate, frame plate and multiple sets of suction cup support rods to descend, forming a multi-point support structure. This effectively prevents the device from tilting and provides multi-point support for the device, effectively preventing the device from tilting during use. This also prevents tilting problems that may be encountered by special groups such as larger or elderly patients, ensuring the stability and safety of treatment. 2. In this invention, the device adopts multiple safety protection measures. The spring-loaded door design prevents the suction cup support rod from extending when not in use, ensuring the safety of the device during carrying and storage. The airbag assembly set on the top of the device can change size by inflating gas, relieving the fatigue of patients sitting for long periods during treatment and improving the patient's comfort. 3. In this invention, the device is driven by a linkage mechanism, and the lifting and lowering of the device and the expansion and contraction of the support mechanism can be controlled by manipulating the display screen. The operation is simple and convenient, and it is suitable for all types of patients. The portable protective case design makes the device easy to carry and store, and convenient for patients to use at home or when they go out. Attached Figure Description
