[0002] Before injecting drugs such as mycin, tetanus antitoxin, cephalosporin, antivenom, tuberculin, etc., a skin test is required to determine whether the patient is allergic to the drug;

[0003] The judgment method is to observe whether the skin mound appears red, swollen, or flushed, and at the same time judge based on whether the diameter of the skin mound is within the allergy diameter range. The existing judgment of the diameter of the skin mound is mainly based on naked eye observation or measurement with a tape measure. The tape measure measurement often cannot accurately align the diameter of the skin mound, resulting in errors in the measurement value. Naked eye observation only relies on experience to judge the diameter of the skin mound, and cannot accurately obtain the value of the skin mound diameter, which makes the skin test prone to errors. Therefore, a standardized skin test measuring ruler is proposed to solve the above problems. Utility Model Content

[0022] It is worth noting that: the inner side of the fixed measuring claw 2 is aligned with the zero scale of the standard comparison ruler 6, and the pointer 7 is aligned with the inner side of the movable measuring claw 3;

[0023] It should be noted that: by placing the skin mound to be tested between the fixed measuring claw 2 and the mobile measuring claw 3, and then pressing the protrusion 5, the L-shaped slide plate 4 drives the mobile detection claw to move, so that the fixed measuring claw 2 and the mobile measuring claw 3 are in contact with the edge of the skin mound to be tested, so that the diameter of the skin mound can be measured, and by comparing with the standard comparison ruler 6 at the same time, it can be accurately determined whether the skin mound to be tested has allergic phenomena.

[0024] The interior of the standard comparison ruler 6 is filled with magnets, and the magnets and the inner wall of the card slot 102 are magnetically attracted to each other;
