Pelvic floor muscle treatment equipment

Technical Field

The present invention relates to a neuromuscular electrical stimulation apparatus for treating female urinary incontinence symptoms, in particular pelvic floor muscle treatment devices of improved fit.

Background

Existing neuromuscular electrical stimulation is widely used to assist people with motor dysfunction in performing muscle contraction movements. In treatment, motor nerve fibers are electrically stimulated by means of a percutaneously applied current pulse to cause contraction of the neuromuscular.

It has been ascertained that female urinary incontinence is caused by the inability of the patient to properly constrict the external urinary sphincter, and treatment has been developed in such a way that neuromuscular stimulation of dysfunctional muscles by vaginal or anal electrodes effectively prevents the occurrence of undesirable urination behavior.

By using such electrodes, the patient may be self-guided, actively or automatically preventing the flow of urine. A more important application of pelvic floor stimulation is the exercise and conditioning of the pelvic floor muscles that support the bladder, vagina, urethra and other organs. The muscles that women become relaxed or stretched during childbirth or natural aging can be strengthened and tightened to properly support the above-mentioned body structures, thereby significantly affecting the patient's ability to remain incontinent.

Electrical stimulators for controlling urinary incontinence typically include a cylindrical vaginal plug. The wiring harness extends from the plug to a controller or stimulator that generates stimulation signals. Cylindrical vaginal electrodes cause compression of the blood vessels supplying the contracting pelvic muscles, which results in discomfort for the patient.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The pelvic floor muscle treatment apparatus of some embodiments of the present invention is described below with reference to fig. 1 and 2.

The pelvic floor muscle treatment device in this embodiment is an electrical neuromuscular stimulation treatment device. Including handheld portion 1 and electrode region 2, its characterized in that, electrode region 2 includes: the outer surface of the non-conductive body 23 is provided with a plurality of conductive areas, the conductive areas and the non-conductive areas are arranged at intervals, the conductive areas comprise conductive rings 3, the outer peripheral surface of each conductive ring 3 is provided with a plurality of protrusions 31, the non-conductive body 23 is cylindrical, an arc-shaped concave part 21 is arranged in the middle of the side surface, and a wiring cavity 24 is arranged in the non-conductive body 23 along the axis of the non-conductive body; the top end 22 is arranged at one end of the non-conductive main body 23 far away from the handheld part 1, the top end 22 is in a frustum shape with a smooth head, and the larger diameter end of the top end 22 is matched with the non-conductive main body 23 and seals the wiring cavity 24; the terminal, terminal block 33 of the terminal is located in the conductive ring 3, terminal head 34 of the terminal extends into the routing cavity 24 and is connected to the power supply conductor, and the conductive area is electrically coupled to the controller by a lead wire (not shown) included in the power supply conductor.

As shown in fig. 1. The electrode area 2 has the shape of an arc-shaped recess 21, the outer surface tapering radially in the arc-shaped recess 21. In addition, the tip 22 is frustoconical in shape with a smooth head that facilitates atraumatic insertion of the electrode zone 2 within the vagina. When the electrode regions 2 are located within the vagina near the dysfunctional pelvic muscles, current from the controller is delivered to the conductive regions. This current causes the pelvic muscles to contract, causing the vaginal wall to press in an uneven manner against the electrode regions 2, conforming to the shape of the arcuate recesses 21. The arc-shaped concave part 21 of the electrode area 2 is not only adapted to the shape of the vagina during contraction to provide protection for the delicate vaginal wall as much as possible, but also helps to keep the electrode area 2 at the required position and is not easy to move out of the treatment area.

In terms of materials, the conductive region may be formed of carbon-supported silicone rubber, and the non-conductive body is formed of non-conductive polymer, which are already known in the art, and this embodiment is only to use the above materials and not to modify them.

Preferably, the controller provides different electrical current stimuli to the different conductive zones at different intensities, e.g., providing a first channel pulse signal at a frequency between about 5Hz and about 20Hz in zone one; a second channel pulse signal having a frequency between about 30Hz and about 100Hz is provided in region two. Thereby making different signals dedicated to stimulating different reflex pathways. Thus, the multiple stimulation intensities of the pelvic floor muscle treatment device provide a condition that is suitable for urinary incontinence caused by different kinds of muscle relaxation.

Because the conductive ring 3 can be an elastic region formed by carbon-loaded silicone rubber, the thickness of the conductive ring 3 is increased as much as possible in the embodiment for better comfort when inserting the device, so that the protrusions 31 on the conductive ring 3 can be elastically pressed into the conductive ring 3 as much as possible when being pressed. But this clearly reduces the available diameter of the routing cavity, and for the sake of routing convenience, the center of the larger diameter end of the top end 22 is provided with a boss 25 outwards, and the end of the non-conductive body 23 away from the hand-held part 1 is provided with a sunken groove, and the boss 25 is adapted to the sunken groove. When installing the power supply wire at the terminal head like this, walk the line chamber and be the open through chamber in both ends, easily wiring operation, after the operation reuse top 22 seal walk the line chamber can, moreover, the space that boss 25 and heavy groove structure occupy is little, nevertheless combines the effect to surely reach the requirement of this embodiment, and interference fit can not make top 22 leave over in the vagina.

Preferably, the conductive ring 3 is further provided with a pressure sensor capable of detecting an applied pressure value averaged over the measurement area; there is also provided an electromyographic response sensor, which is a sensor capable of measuring an electrical signal produced by a muscle relative to a reference sensor.

It is well known that electrodes are placed along the vaginal wall in a position to apply electrical stimulation therapy for muscle stimulation. The present embodiment adds to the conductive ring 3 tactile and electromyographic sensors that register the tactile response from the vaginal wall, which sensors have been used in other muscle stimulation treatments.

The conductive ring 3 is formed of carbon-loaded silicone rubber so that pressure sensors for sensing tactile response and electromyographic response sensors may be injection molded together as a unit when molded, preferably the pressure sensors and electromyographic response sensors are evenly arranged circumferentially along the conductive ring 3, and the pressure sensors and electromyographic response sensor arrays may be configured to record signals during contraction of pelvic floor muscles and resting muscles. Comparison of the measured pressure values at muscle relaxation can yield data on the muscle tone, which can be considered an important characteristic of the muscle condition.

Haptic and electromyographic signal acquisition may be synchronized in time. The electromyographic response sensor and the pressure sensor have the same circumferential spatial position relative to the conductive ring 3, at a selected position relative to the reference electrode, the location of, for example, electrical stimulation is located onto the vaginal wall. Electromyographic response sensors may also be used as stimulation electrodes relative to reference electrodes, and in embodiments, electrical stimulation pulses relative to at least one reference electrode may be applied to the vaginal wall at one or more selected locations within the vagina, or may be placed on the skin surface near the bladder or between the vagina and anus.

In order to accurately register the tactile and electromyographic responses, the electrode regions 2 must remain in position without any displacement. During treatment, the vaginal wall is pressed in an uneven manner into the curved recesses 21 of the electrode areas 2, and the patient can be relieved of the physician's instructions to follow specific instructions for a given time or voluntary (coughing) muscle contraction and specific manipulations (e.g. limb motor completion).
