Electrical stimulator

Abstract

To provide an electrical stimulator that allows defective electrical connections to be detected readily. This electrical stimulator 1 comprises an electrode group 10 comprising three or more electrodes, and a drive means 20 for energizing the electrode group 10. The drive means 20 is constituted in such a manner as to assign a first polarity to one electrode among the electrode group 10 and a second polarity to the remaining plurality of electrodes, and to energize the electrode group 10 by sequentially switching the electrode having the first polarity. In addition, this electrical stimulator 1 comprises a defective connection detection means 30 that detects a defect in the electrical connection by detecting whether or not electrical stimuli have been applied to the user when the electrode group 10 has been energized.

Description

technical field

[0001] The present invention relates to an electrical stimulation device for providing electrical stimulation to a body using an electrode set having more than three electrodes. Background technique

[0002] In recent years, electrical stimulation devices have been known that provide electrical stimulation to the body by contacting electrodes to predetermined positions of the body to perform muscle training and the like. Such electrical stimulation devices include, for example, devices that supply energy to specific pairs of electrodes and provide electrical stimulation between these electrodes. For example, a device is described in Patent Document 1, which is provided with electrode segments A1 and A2 adapted to the lower waist of the patient's body, and electrodes B and C respectively adapted to the flanks on the opposite side of the patient's body, and alternately provided on the electrode segments A1 and A2. A first set of muscle stimulating current puls...
