Abstract

An optical treatment apparatus includes: a power source unit; a light irradiation module, that irradiates an affected part with light; a spacer that is positioned between the light irradiation module and the affected part; a fixing material that applies pressure to the light irradiation module and fixes the light irradiation module at an installation position; and a shielding material that covers the light irradiation module, in which, in a case where the pressure applied by the fixing material becomes lower than predetermined pressure, supply of current is stopped.

First claim

The invention claimed is:

1. An optical treatment apparatus comprising:
a power source unit;
a light irradiation module that irradiates a target with light when current is supplied from the power source unit;
a transparent spacer that is positioned between the light irradiation module and the target;
a fixing material that applies predetermined pressure so as to press the light irradiation module against the transparent spacer and fixes the light irradiation module at an installation position;
a light shielding unit that is provided between the light irradiation module and the fixing material and covers the light irradiation module;
at least one pair of electrodes connected to the power source unit and provided on a surface of the light irradiation module, which is on a side of the light shielding unit; and
a conductive unit that is provided at a position facing the at least one pair of electrodes on a surface of the light shielding unit, which is on a side of the light irradiation module, wherein
in a case where the power source unit detects that the at least one pair of electrodes is nonconductive, the power source unit stops the supply of the current to the light irradiation module.

2. The optical treatment apparatus according to claim 1 , wherein
the light irradiation module includes a temperature sensor, and
in a case where the temperature sensor detects temperature higher than predetermined temperature, the supply of the current to the light irradiation module is stopped.

3. The optical treatment apparatus according to claim 1 , wherein, in a state where the light irradiation module is fixed by the fixing material, the light shielding unit covers a whole of the transparent spacer and a minimum distance from an end of the transparent spacer to an end of the shielding unit is at least 5 mm or more.

4. The optical treatment apparatus according to claim 1 , wherein the light shielding unit covers the transparent spacer and turns below the transparent spacer at an entire periphery of the transparent spacer, and at a bottom of the transparent spacer a minimum distance between an end of the light shielding unit and an edge of the transparent spacer is at least 2.0 mm or more.

5. An optical treatment apparatus comprising:
a power source unit;
a light irradiation module that irradiates a target with light when current is supplied from the power source unit;
a transparent spacer that is positioned between the light irradiation module and the target;
a fixing material that applies predetermined pressure so as to press the light irradiation module against the transparent spacer and fixes the light irradiation module at an installation position; and
a light shielding unit that is provided between the light irradiation module and the fixing material and covers the light irradiation module, wherein
the light irradiation module has a plurality of light emitting elements uniformly arranged on a flexible substrate and a pressure sensor connected to the power source unit,
an area of the transparent spacer is equal to or greater than an area of the light irradiation module, and
in a case where the pressure sensor senses that pressure applied by the fixing material becomes lower than the predetermined pressure, the power source unit stops the supply of the current, and
in a case where existence of the light shielding unit is not detected, the supply of the current is stopped.

6. The optical treatment apparatus according to claim 5 , further comprising a sensor, wherein the power source unit stops the supply of the current in response to a signal from the sensor.

7. The optical treatment apparatus according to claim 5 , further comprising a current switch between the light irradiation module and the power source unit, wherein, when the current switch is opened, the supply of the current is stopped.

8. The optical treatment apparatus according to claim 5 , wherein
the light irradiation module includes a temperature sensor,
the temperature sensor measures temperature of the light irradiation module, and
in a case where the temperature sensor detects temperature higher than predetermined temperature, the supply of the current to the light irradiation module is stopped.

9. The optical treatment apparatus according to claim 5 , wherein, in a state where the light irradiation module is fixed by the fixing material, the light shielding unit covers an whole of the transparent spacer and a minimum distance from an end of the transparent spacer to an end of the shielding unit is at least 5 mm or more.

10. The optical treatment apparatus according to claim 5 , wherein the light shielding unit covers the transparent spacer and turns below the transparent spacer at entire periphery of the transparent spacer, and at a bottom of the transparent spacer a minimum distance between an end of the light shielding unit and an edge of the transparent spacer is at least by 2.0 mm or more.

11. An optical treatment apparatus comprising:
a power source unit;
a light irradiation module that irradiates a target with light when current is supplied from the power source unit;

in a case where pressure applied by the fixing material becomes lower than the predetermined pressure, the current switch opens to stop the supply of the current,
the current switch includes an upper electrode and a lower electrode, and
the upper electrode is provided on a surface of the fixing material, which is on a side of the target, and the lower electrode is provided at a position facing the upper electrode on a surface of the light shielding unit, which is on a side of the fixing material, or around the target.

12. An optical treatment apparatus comprising:
a power source unit;
a light irradiation module that irradiates a target with light when current is supplied from the power source unit;
a transparent spacer that is positioned between the light irradiation module and the target;
a fixing material that fixes the light irradiation module and the transparent spacer to be on the target; and
a light shielding unit that covers the light irradiation module and the transparent spacer, wherein
