Description

Technical Field

[0001] The present invention belongs to the field of neuromuscular technology, and specifically relates to a neuromuscular electrical stimulation device and a method of use. Background Art

[0002] A neuromuscular electrical stimulation device is a medical device that uses specific electric current pulses to stimulate nerve and muscle tissue. It is usually composed of a host, electrodes, wires, etc. The host generates electrical stimulation signals with different parameters (such as frequency, intensity, pulse width, etc.), which are transmitted to the electrodes through wires. The electrodes transmit these signals to the skin surface, thereby acting on the nerves and muscles.

[0003] When using a neuromuscular electrical stimulation device, you should first determine the nerves and muscles that need to be stimulated based on the purpose of treatment, then stick the electrodes on the selected parts, making sure that the electrodes are in close contact with the skin without wrinkles or bubbles. At the same time, keep an appropriate distance between the electrodes to ensure that the current can evenly stimulate the target area. After confirming that the electrodes are placed correctly, start the electrical stimulation device and begin treatment.

[0004] However, the electrode patch can be repeatedly applied and removed about 10 times, but the stickiness will decrease with the number of uses. After multiple uses, the adhesive on the electrode patch may lose some of its stickiness, making it difficult to stick firmly to the skin, which can easily cause the device to fall off. In addition, if there are impurities such as oil, sweat, and dust on the skin surface, the adhesion between the electrode patch and the skin will be reduced. During the treatment process, physical activity or sweating may also cause the electrode patch to gradually loosen and eventually fall off. Frequent falling of the electrode patch will lead to interruption of electrical stimulation, making it impossible for the nerves and muscles to continue to receive stable stimulation, which will disrupt the rhythm and continuity of the treatment and reduce the treatment effect.
