Abstract

A muscle electrostimulation device has a main body having a contact surface fitted around an abdomen. The contact surface extends in an X direction encircling the abdomen and in a Y direction perpendicular to the X direction. The main body includes: a front part having a front electrode unit adapted to cause an electric current in the X direction in an abdominal rectus muscle; and a pair of extensions extending from respective sides of the front part in the X direction and having side electrode units adapted to cause an electric current in the X direction to flow in an oblique abdominal muscle. Front recesses that recede in the Y direction are provided at positions in side portions of the front part along the Y direction that bisect the front part in the X direction.

Claims

1. A muscle electrostimulation device comprising:

a main body having a contact surface fitted around an abdomen, wherein

the contact surface extends in an X direction encircling the abdomen and in a Y direction perpendicular to the X direction,

the main body including;

a front part having a front electrode unit adapted to cause an electric current in the X direction in an abdominal rectus muscle; and

a pair of extensions extending from respective sides of the front part in the X direction and having side electrode units adapted to cause an electric current in the X direction to flow in an oblique abdominal muscle, wherein

front recesses that recede in the Y direction are provided at positions in side portions of the front part along the Y direction that bisect the front part in the X direction.

3. The muscle electrostimulation device according to claim 1, wherein

boundary recesses that recede in the Y direction are provided on respective sides of the main body along the Y direction at respective boundaries between the front part and the pair of extensions.

4. The muscle electrostimulation device according to claims 1, wherein

the main body includes a first base member, a second base member, and a cover member,

the first base member has an opening that exposes the front electrode unit and the side electrode units,

the second base member is provided with the front electrode unit and the side electrode units, and

the cover member is built on a side of the second base member opposite to the first base member and covers the front part and the pair of extensions so as to integrate the front part and the pair of extensions.

5. The muscle electrostimulation device according to claim 4, wherein

the cover member has an edge cover portion that covers outer edges of the first base member and the second base member.

2. A muscle electrostimulation device comprising:

a main body having a contact surface fitted around an abdomen, wherein

the contact surface extends in an X direction encircling the abdomen and in a Y direction perpendicular to the X direction,

the main body including;

a front part having a front electrode unit adapted to cause an electric current in the X direction in an abdominal rectus muscle; and

a pair of extensions extending from respective sides of the front part in the X direction and having side electrode units adapted to cause an electric current in the X direction to flow in an oblique abdominal muscle, wherein

a dimension of the pair of extensions in the Y direction is configured to be smaller than a dimension of the front part in the Y direction.

6. A muscle electrostimulation device comprising:

a main body having a contact surface fitted around an abdomen, wherein

the contact surface extends in an X direction encircling the abdomen,

the main body including;

a front part having a front electrode unit adapted to cause an electric current in the X direction in an abdominal rectus muscle; and

a pair of extensions extending from respective sides of the front part in the X direction and having side electrode units adapted to cause an electric current in the X direction to flow in an oblique abdominal muscle, wherein

the main body is provided with a control unit that supplies a voltage to the front electrode unit the pair of side electrode units, and

the control unit is configured to switch between an independent control mode for controlling supplied voltages independently and a concurrent control mode for controlling the supplied voltages concurrently.
