## Abstract

There is disclosed an ultrasonic probe, and more particularly, an ultrasonic probe configured to visually provide a change based on an ultraviolet (UV) response during UV disinfection. The ultrasonic probe according to one aspect of the present disclosure is provided such that a coated layer formed of a UV-sensitive material is provided on a surface of the ultrasonic probe, and the UV-sensitive material provided in the coated layer is discolored.

## Claims

### Claim 1

An ultrasonic probe comprising a coated layer formed on a surface thereof and formed of an ultraviolet (UV)-sensitive material having a property of light discoloration,
wherein the UV-sensitive material provided in the coated layer is discolored during UV irradiation.

### Claim 2 (depends on 1)

The ultrasonic probe of claim 1, wherein the coated layer is coated with a pigment in which a powder type material having the property of light discoloration and at least one of an organic solvent and a water-soluble solution are mixed.

### Claim 3 (depends on 1)

The ultrasonic probe of claim 1, wherein the coated layer is formed on at least a part of a surface of the ultrasonic probe.

### Claim 4 (depends on 1)

The ultrasonic probe of claim 1, further comprising:
a case configured to accommodate a transducer module; and
a lens installed at one end of the case,
wherein the coated layer is formed on at least one of the case and the lens.

### Claim 5 (depends on 4)

The ultrasonic probe of claim 4, further comprising a strain reliever provided at the other end of the case, wherein the coated layer is formed on the strain reliever.

### Claim 6 (depends on 1)

The ultrasonic probe of claim 1, wherein the UV-sensitive material having the property of light discoloration includes a UV-sensitive material having the property of light discoloration including at least one selected from the group consisting of a fulgide-based molecule, a diarylethene-based molecule, an azobenzene-based molecule, a spirooxazine-based molecule, and a spiropyran-based molecule.

### Claim 7 (depends on 6)

The ultrasonic probe of claim 6, wherein the diarylethene-based molecule includes at least one selected from the group consisting of thiophene perfluoropentane, benzothiophene perfluoropentane, benzothiophene maleicanhydride, benzothiophene cyanoethene, a benzothiophene perfluoropentane derivative, a benzothiophene sulfone perfluoropetene derivative, a benzothiophene perfluoropetene polymer, and a benzothiophene sulfone perfluoropetene polymer.
