Abstract

Provided is a detection tool that detects a temperature of air. The detection tool includes a detection section that detects a temperature of air released from an air turbine handpiece, and a main body that includes a surface. The detection section is provided on the surface to allow the air turbine handpiece to be brought close to the detection section.

First claim

What is claimed is:

1. A detection tool, comprising:
a detection sensor configured to detect a temperature of air released from an air turbine handpiece; and
a main body that includes a surface, the detection sensor being disposed on the surface to allow the air turbine handpiece to be brought close to the detection sensor,
wherein the air turbine handpiece includes a head and a cutting tool attached to the head, the air turbine handpiece is configured to rotate the cutting tool by a driving force generated by air, the detection sensor includes a thermo-sensitive material which changes color in response to a temperature change, and the thermo-sensitive material changes color when detecting air having a temperature of about 40° C. or more.

2. The detection tool according to claim 1 , wherein
once the color of the thermo-sensitive material is changed, the thermo-sensitive material does not return to an original color.

3. The detection tool according to claim 1 , wherein
the main body includes a region describing the content of color changes of the thermo-sensitive material.

4. The detection tool according to claim 1 , wherein
the detection sensor has a shape serving as a target onto which the air released from the air turbine handpiece is blown.

5. The detection tool according to claim 4 , wherein
the detection sensor has a size equal to or greater than a size of a head of the air turbine handpiece.

6. The detection tool according to claim 1 , wherein
the main body includes a region describing a detection process for detecting the temperature of air released from the air turbine handpiece by using the detection sensor,
the detection process including driving the air turbine handpiece to operate for a predetermined time and bringing the air turbine handpiece close to the detection sensor within a predetermined distance.

7. The detection tool according to claim 6 , wherein
the detection process includes bringing a head of the air turbine handpiece close to the detection sensor within the predetermined distance.

8. The detection tool according to claim 6 , wherein
the predetermined time is two seconds or more.

9. The detection tool according to claim 6 , wherein
the predetermined distance between the detection sensor and the air turbine handpiece is 1 mm to 10 mm.

10. A detection method, comprising:
detecting, with a detection sensor on a main body, a temperature of air released from an air turbine handpiece, the main body including a surface on which the detection sensor is disposed to allow the air turbine handpiece to be brought close to the detection sensor; and
changing a color on the detection sensor on the main body in response to the detected temperature of the air released from the air turbine handpiece being above a predetermined threshold,
wherein the air turbine handpiece includes a head and a cutting tool attached to the head, the air turbine handpiece is configured to rotate the cutting tool by a driving force generated by air, the detection sensor includes a thermo-sensitive material which changes color in response to a temperature change, and the thermo-sensitive material changes color when detecting air having a temperature of about 40° C. or more.
