[0031] Example 1

[0032] Please refer to Figure 1-4The pruritus grading ruler, used in the field of pruritus assessment, mainly consists of: 1. the ruler body; 2. multiple touch areas; 3. an area for posting pruritus grades and symptom descriptions; 4. a U-shaped indicator rod; and 5. detachable fasteners.

[0033] The ruler body 1, as the main body of the measuring ruler, has multiple touch areas 2 arranged sequentially on the upper edge of its surface. These touch areas 2 are used to simulate different degrees of itching, allowing users to feel and judge their own degree of itching by touching these areas. The lower edge of the ruler body 1 has an itching level and symptom description posting area 3 corresponding to the touch areas 2. This area can be used to post the corresponding itching level and symptom description for users to refer to.

[0034] To more accurately indicate the current level of itching, a U-shaped indicator rod 4 is also provided on the ruler body 1. Both ends of the U-shaped indicator rod 4 are slidably installed in the grooves 5 on both sides of the ruler body 1, so that the U-shaped indicator rod 4 can slide left and right along the grooves 5 to indicate the current level of itching. The outer wall of the U-shaped indicator rod 4 is also provided with anti-slip marks 11 to prevent hand slippage. These anti-slip marks 11 can increase the roughness of the surface of the U-shaped indicator rod 4, improve the user's feel, and prevent hand slippage during use.

[0035] To facilitate fixing the ruler 1 in the usage position, the ruler 1 is also provided with a detachable fixing component. In this embodiment, the detachable fixing component includes two manual suction cups 6 set at both ends of the ruler 1. A connecting piece 7 is fixedly set on the top of the manual suction cup 6. The ruler 1 can be easily adsorbed onto a smooth surface, such as a desktop or wall, by means of the manual suction cup 6.

[0036] Mounting brackets 8 are fixedly installed at both ends of the ruler body 1. The top of the connecting piece 7 can be inserted into the mounting bracket 8.
