Description

A new type of probe for pelvic floor muscle rehabilitation therapy instrument and its application method

technical field

The invention relates to a novel probe used in a pelvic floor muscle rehabilitation treatment instrument and a method of use thereof, in particular to a novel probe capable of simultaneously collecting myoelectricity and pressure signals and electrically stimulating muscles and a method of use thereof.

Background technique

The current non-surgical treatment for pelvic floor muscle rehabilitation is mainly to perform pelvic floor muscle contraction exercise by the patient himself, supplemented by external electrical stimulation, and at the same time convert the information of muscle activity into auditory and visual signals through the collected electromyogram and pressure curve Give feedback to the patient, guide the patient to perform correct and autonomous pelvic floor muscle training, and form conditioned reflexes.

At present, there are two kinds of probes for the well-known pelvic floor muscle rehabilitation treatment instrument, one is the myoelectric stimulation and collection probe, which acts on the pelvic floor muscles with the electric stimulation of the external treatment instrument through metal electrodes and collects the myoelectric signal. For example, the surface of the probe described in the patent No. "CN2848126Y" and titled "A Vaginal and Anal Probe" in 2006 is equipped with a number of contact electrodes, which are ring-shaped or sheet-shaped, and can pass in stimulation current and feedback. EMG signal transmission.

The other is the pressure acquisition probe, which is mainly an air bag. When the pelvic floor muscles contract, the muscles exert a certain pressure on the air bag, so the internal pressure of the air bag changes. From the force balance, the pressure of the muscle contraction is the same as the pressure of the air bag. The generated external pressure is equal in magnitude, and the probe collects the pressure signal into the therapeutic apparatus by detecting the pressure of the muscle contraction or the pressure of the air bag. The practicability of this kind of probe is relatively poor, and there is an inflation process before each use, which is troublesome, and the temperature also affects the pressure of the gas, so the test result is inaccurate. For example, the probe described in the 2008 patent No. "CN101146478A" entitled "A Device for Examining and Treating Urinary Incontinence and Exercising Female Vaginal Muscle Biofeedback" is an inflatable air bag made of rubber, etc., used When the muscle relaxes, the inflator inflates the airbag, and the pressure sensor on the surface of the airbag senses the pressure of the muscle to control the time to stop inflating. After stopping the inflation, the muscle contracts, and the pressure sensor can measure the pressure during contraction. Another example is the patent No. "CN103622710A" and the 2014 patent titled "A Vaginal Contraction Rehabilitation Treatment Equipment". Air pressure to control the time to stop inflation and the pressure change when the muscles contract.

The two existing probes on the market cannot combine the function of myoelectric stimulation and acquisition with the function of pressure acquisition. As a result, the current pelvic floor muscle rehabilitation therapy instrument can only feed back one of the electromyogram or pressure curve to the patient. The patient cannot get the information of muscle synthesis, and the effect of the therapeutic instrument to guide the patient to perform pelvic floor muscle training will be greatly reduced.

Therefore, in order to greatly improve the therapeutic effect of pelvic floor rehabilitation, it is necessary to find a way to realize the functions of myoelectric stimulation and acquisition and pressure acquisition on the same probe, so as to ensure that patients can receive comprehensive information of electromyography and pressure curves at the same time , The therapeutic instrument can guide patients to perform more correct pelvic floor muscle training.

After reviewing related patents, we found that the carrier described in a 1990 patent titled "Method and Apparatus for Mounting a Body Cavity Electrode to a Patient" with patent number "1042084" can also achieve electrical stimulation and acquisition as well as pressure acquisition , which achieves electrical stimulation and myoelectric collection through a ring-shaped metal electrode, and collects pressure through an expandable hollow ring injected with fluid next to the electrode. This kind of hollow ring injected with fluid has a small contact area with the skin, and the deformation caused by muscle contraction is small, the pressure signal collected is not accurate, and the manufacturing process is relatively complicated, and there is a risk of fluid leakage. Our solution is to achieve electrical stimulation and myoelectric collection through a loose and soft elliptical conductive film, which does not harm the skin, and collects pressure through a spring connected to the film. In the solution, the two ends of the long axis of the elliptical section of the cylinder carrier The protruding structure makes it more sensitive to feel the pressure, the spring can produce more accurate deformation, and obtain a more accurate pressure signal, and the manufacturing process is simple.

Further, the film material can be a conductive film, which meets biocompatibility and can be placed in the body, and the elastic material can be one or more springs.

Electrical stimulation is transmitted to the muscles through the first channel connected to the patch (this first channel is time-division multiplexed and also used to transmit the myoelectric signal) and the patch to the muscles, and the muscles receive stimulation. (b) Acquisition of pressure signals: self-contracting muscles through the feedback of the electromyography and pressure maps of the in vitro equipment: pressure is generated on the film at both ends of the long axis of the elliptical section of the cylinder carrier. The protruding structure at both ends makes it sensitive to force, which can accurately feel the pressure and generate a pressure signal. The middle part of the film is concave, and the elastic parts connected to the film are deformed, and the pressure signal is transmitted to the pressure sensor. The pressure sensor transmits the pressure signal It is converted into an electrical signal, and the pressure signal is transmitted to the external device through the second channel connected to it. (c) EMG signal acquisition: the oval-shaped film on both sides of the carrier senses the EMG signal and transmits the signal through the first channel connected to the film (this first channel is time-division multiplexed and is also used to transmit electrical stimulation into the body). to in vitro equipment.

According to the novel probe of the pelvic floor muscle rehabilitation treatment instrument implemented in the present invention, the pressure generated by the muscles can be sensitively felt due to the protruding structure at both ends of the long axis of the elliptical cross-section of the carrier cylinder when the muscles contract, thereby making the film concave, The elastic component produces more accurate deformation, so that a more accurate pressure signal can be obtained through the pressure sensor.

According to the novel probe of the pelvic floor muscle rehabilitation treatment instrument implemented in the present invention, the electric stimulation can be transmitted to the oval film through the metal conductivity of the elastic component and the myoelectric signal is transmitted to the external equipment, and the pressure can be transferred by the elasticity of the elastic component. Transmitted to the outside of the body through a pressure sensor. In this way, the three functions of myoelectric stimulation, myoelectric acquisition and pressure acquisition are realized on one probe at the same time, which not only facilitates the use of patients, but also makes patients more aware of their physical state, which is more conducive to the rehabilitation of patients.
