If there is a risk of tetanus infection from an open wound, prophylaxis should be initiated promptly.

[0003] An intradermal test is required before tetanus antitoxin injection to prevent an allergic reaction. After performing a skin test, medical staff need to observe the redness on the patient's skin to determine whether the patient is allergic. However, some patients experience irregular redness, similar skin color, or a size that falls between an allergic and non-allergic reaction. This makes it difficult for medical staff to intuitively determine the redness.

[0016] Beneficial effects:

[0017] The utility model provides a tetanus skin test result interpretation ruler. When the skin test on the patient's skin is difficult to directly observe, the medical staff holds the interpretation ruler main body and places the secondary ruler on the patient's skin. The red blush is located in the second through-slot. Because the rectangular through-slot corresponds to the second through-slot and the width of the second through-slot is smaller than the rectangular through-slot, the red blush in the second through-slot can be observed from above the rectangular through-slot. The medical staff first slides the convex lens in the rectangular through-slot, slides the convex lens to one side of the red blush, and simultaneously observes the red blush edge and the scale number on the secondary ruler. Then, the convex lens is moved to the other side of the red blush, and the medical staff observes the other side of the red blush and the scale number on the secondary ruler. By subtracting the two scale numbers, the size of the red blush on the patient's skin test can be calculated, thereby determining whether the patient is allergic. The device is simple to use, simple in structure, and inexpensive to manufacture. It can help medical staff accurately judge the red blush, avoid allergic reactions in patients undergoing tetanus injections, and avoid unnecessary medical accidents. It improves efficiency and reduces the rate of misjudgment.

[0027] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the embodiments described are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this utility model.

[0028] Meanwhile, in the embodiments of this specification, when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component.

[0029] See also Figure 1-3This embodiment provides a tetanus skin test result interpretation ruler, which includes a ruler body 1, having a rectangular through-slot 11 defined along the ruler body, and a convex lens 12 secured within the rectangular through-slot 11 and slidable along the length of the ruler body within the rectangular through-slot 11; a secondary ruler 2, which is spaced apart and mounted below the ruler body 1 so that the focal point of the convex lens 12 is located on the secondary ruler 2, and a second through-slot 21 defined on the secondary ruler 2 opposite the rectangular through-slot 11. A scale is marked along the second through-slot 21 on a side of the secondary ruler 2 facing the ruler body 1.

[0030] Specifically, when the skin test on the patient's skin is difficult to observe directly, the medical staff holds the reading ruler body 1 and places the secondary ruler 2 on the patient's skin. The red blush is located in the second through-slot 21. Because the rectangular through-slot 11 corresponds to the second through-slot 21 and the width of the second through-slot 21 is smaller than that of the rectangular through-slot 11, the red blush in the second through-slot 21 can be observed from above the rectangular through-slot 11. The medical staff first slides the convex lens 12 in the rectangular through-slot 11, slides the convex lens 12 to one side of the red blush, and simultaneously observes the red blush edge and the scale number on the secondary ruler 2. Then, the convex lens 12 is slid to the other side of the red blush, and the medical staff observes the other side of the red blush and the scale number on the secondary ruler 2. By subtracting the two scale numbers, the size of the red blush on the patient's skin test can be calculated, thereby determining whether the patient is allergic. The device is simple to use, simple in structure, and inexpensive to manufacture, but it can help medical staff accurately judge the red blush, avoid allergic reactions in patients undergoing tetanus injections, and avoid unnecessary medical accidents, thereby improving efficiency and reducing the rate of misjudgment.

[0031] In some possible implementations, the length of the ruler body 1 is not less than 20 cm, the length of the rectangular through slot 11 is not greater than half the length of the ruler body 1 , and the rectangular through slot 11 is located on one side of the midpoint of the length direction of the ruler body 1 .

[0032] Specifically, the 20 cm reading ruler main body 1 is easy to use. The patient holds one end of the reading ruler main body 1 and can place the other side of the secondary ruler 2 close to the patient's skin. The position of the rectangular through-slot 11 limits the position of the secondary ruler 2. Generally, a positive diagnosis can be made when the patient's blush exceeds 4 cm. The length of the rectangular through-slot 11 does not need to be too long. A moderate length is more convenient to use and does not appear cumbersome.

[0033] In some possible embodiments, two card slots 13 are provided on the two long sides of the rectangular through slot 11, and a mirror holder 14 is installed on the outer ring of the convex lens 12. Card strips 15 adapted to the two card slots 13 are provided on both sides of the mirror holder 14 in contact with the rectangular through slot 11. The two card strips 15 are clamped in the two card slots 13, and the convex lens 12 is clamped in the rectangular through slot 11 through the mirror holder 14.

[0034] Specifically, two card slots 13 are provided on the two long sides of the rectangular through-slot 11, i.e., the main body 1 of the ruler. The card strips 15 on both sides of the mirror holder 14 of the convex lens 12 can be snapped into the two card slots 13. The mirror holder 14 can slide in the card slots 13 to change the position of the convex lens 12. The mirror holder 14 protects the convex lens 12 from wear and tear, and makes sliding smoother and more convenient.

[0035] In some possible implementations, the length of the secondary ruler 2 is not less than the length of the rectangular through slot 11 , and the two long sides of the secondary ruler 2 are installed below the reading ruler body 1 with two transparent side walls 22 spaced apart.

[0036] Specifically, the length of the secondary ruler 2 needs to be greater than the length of the rectangular through slot 11. The secondary ruler 2 and the reading ruler body 1 are connected by a transparent side wall 22. The transparent side wall allows light to pass through, so that medical staff can see the blush and scale more clearly.

[0037] In some possible implementations, a support plate 16 is mounted on the mirror support 14. A rubber layer is provided on the bottom surface of the secondary ruler 2.

[0038] Specifically, when medical staff need to drag the convex lens 12, it is more convenient to drag the support plate 16 on the mirror holder 14, and the hands do not need to touch the convex lens 12, so the mirror surface of the convex lens 12 will not be dirty. The bottom surface of the secondary ruler 2 needs to be in close contact with the patient's skin, and a rubber layer is provided on its bottom surface to avoid causing indentations on the patient's skin.

[0039] In some possible implementations, a circular plane mirror 3 is installed on the half of the ruler body 1 away from the secondary ruler 2 , and a plurality of concentric circles are marked on the circular plane mirror 3 .

[0040] Specifically, when the patient's skin color is significantly different from the blush color and is easy to judge, the circular plane mirror 3 on the other side of the reading ruler body 1 is aimed at the patient's skin blush. The blush is exposed in the circular plane mirror 3. The concentric circles in the circular plane mirror 3 can be circles with diameters of 2 cm or 3 cm. The allergy is judged based on whether the size of the blush displayed in the circular plane mirror 3 is larger than the concentric circles of each diameter, which makes the operation simpler.

[0041] In some possible embodiments, the secondary ruler 2 is marked with scale along both sides of the length of the second through slot 21. The second through slot 21 is 8 cm long, and the scale marks on the second through slot 21 are 8 cm. The smallest scale mark on the second through slot 21 is 0.1 cm. Both the ruler body 1 and the secondary ruler 2 are made of transparent plastic.

[0042] Specifically, scales are marked on both sides of the second through-slot 21, making it easier for medical personnel to measure the size of the blush. In a skin test, a blush greater than 4 cm indicates an allergy. Therefore, the 8 cm length of the second through-slot 21 is sufficient for use. The smallest scale mark on the second through-slot 21 is 0.1 cm, which is more precise. The transparent material is light-transmissive and does not affect the magnification of the blush by the convex lens 11, helping medical personnel see more clearly.
