Problems solved by technology

Now NEMS has been used many times for the recovery of Sn with generally positive but mixed results
[0007] However, most of the currently used electrical stimulators are open-loop stimulation without feedback links. The common method for selecting the stimulation mode is to use clinical or experimental experience, and the treatment always uses this stimulation mode, without considering whether the st

Embodiment 1

[0058] Example 1: Electrical stimulation therapy device capable of intelligently adjusting myoelectric threshold

[0059] Myoelectric signal acquisition probe. It includes a myoelectric detection electrode, and the myoelectric detection electrode can be an electrode known in the prior art in the field of medical equipment, and generally includes an electrode body and an electrode sleeve. The myoelectric signal acquisition probe can communicate with the myoelectric signal amplification processing unit by wire or wirelessly. The shape and size of the EMG signal acquisition probe are as follows: figure 2 or image 3 shown.

[0060] Myoelectric signal amplification processing unit. It mainly includes four modules: EMG signal receiving module, EMG signal amplifying module, analog signal and digital signal conversion module, and digital signal transmission module. The myoelectric signal receiving module receives the myoelectric signal measured by the myoelectric signal acquisi...

Embodiment 2

[0064] Embodiment 2: Operation method of electrical stimulation therapy device

[0065] 1. Obtain the initial myoelectric potential threshold of the pelvic floor-related muscle groups:

[0066] 1. Test the myoelectricity of the pelvic floor muscles in the resting stage: under the condition that the relevant muscle groups and nerve plexus of the pelvic floor are completely relaxed, continuously test the average myoelectricity value for 60 seconds.

[0067] 2. Test the initial threshold of the second type of muscle fiber: 60 seconds after the rest period; then do the first rapid contraction for 2.5 seconds, rapid relaxation for 2.5 seconds, and relaxation for 10 seconds. The second fast contraction is 2.5S, rapid relaxation is 2.5S, and relaxation is 10S. The third is to contract rapidly for 2.5S, relax rapidly for 2.5S, and relax for 10S. The fourth is to contract quickly for 2.5S, relax quickly for 2.5S, and relax for 10S. The fifth is to contract quickly for 2.5S, relax qu...

Embodiment 3

[0076] Example 3 Clinical Application of an Electrical Stimulation Therapy Device That Can Intelligently Adjust Myopotential Threshold

[0077] According to the "Guidelines for the Diagnosis and Treatment of Urological Diseases in China", 50 cases of urinary incontinence patients with mild to moderate female ages between 35 and 55 years old and a course of disease between 0.5 and 15 years were collected from the hospital. According to the following criteria, 42 eligible subjects were screened: no clear abnormalities of the genitourinary system were found in the physical examination, no obvious abnormalities were found in the urine routine or culture, and no organic lesions were found in the ultrasound examination of the genitourinary system. 42 patients were randomly divided into control group (20 cases) and treatment group (22 cases).

[0078] The control group was treated according to the conventional method of low-frequency electrical stimulation of pelvic floor muscles in ...

Abstract

The invention provides a method of controlling an output current intensity and an electric stimulation therapeutic instrument used for controlling the output current intensity through the method. The control method comprises the following steps of testing a pelvic-floor-muscle front resting stage muscle potential and an initial muscle potential threshold of a pelvic floor correlation muscle group; and according to the tested muscle potential threshold, adjusting a system threshold and outputting a corresponding electric stimulation signal. By using the method and the electric stimulation therapeutic instrument, through biological feedback training, according to a specific condition of a subject, a system threshold is automatically adjusted.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a method for controlling output current intensity, an electrical stimulation therapeutic apparatus capable of intelligently adjusting a threshold, and the use of the method and the electrical stimulation therapeutic apparatus in treating and alleviating urinary incontinence-related diseases. Background technique [0002] Urinary incontinence affects millions of people, causing discomfort and embarrassment, sometimes to the point of social isolation. In the United States, recent studies indicate that 25 million of them (approximately 85% of whom are women) are affected by bladder control problems. Urinary incontinence also occurs in children and young adults, but most of those affected are those over middle age. [0003] There are several major forms of urinary incontinence, including stress incontinence, stress incontinence, overflow incontinence, and reflex incontinen...
