[0021] The principle and features of the utility model are described below, and the embodiments are only used for explaining the utility model and are not used for limiting the scope of the utility model.

[0022] As Figure 1 shown in the figure, the medical multifunctional ruler of the embodiment comprises a shell 1 with a cavity, a right-angle shaped notch 4 formed by an x measuring edge 2 and a y measuring edge 3 is opened on the side wall of the shell 1, a first opening 5 communicating with the internal cavity of the shell 1 is opened on the outer wall of the shell 1 near the outer end of the x measuring edge 2, and a second opening 6 communicating with the internal cavity of the shell 1 is opened on the outer wall of the shell 1 near the outer end of the y measuring edge 3. Two tape measures, i.e. a tape measure one 10 and a tape measure two 11, are arranged in the shell 1. The structure of the tape measures is the same as that of the soft tape measure of the prior art, the shell thereof is the shell 1, the soft ruler part of the two soft tape measures is wound in the shell, the soft tape measure itself has a button for resetting the wound tape measure, and the button is installed on the shell 1. The outer end of the tape measure one 10 is extended through the first opening 5 and can be extended along the extension line direction of the x measuring edge 2 and has a blocking piece preventing the outer end from being retracted (it is the prior art and will not be described here again). The outer end of the tape measure two 11 is extended through the second opening 6 and can be extended along the extension line direction of the y measuring edge 3, and the outer end of the tape measure two 11 has a blocking piece preventing the outer end from being retracted (it is the prior art and will not be described here again).

[0023] When it is needed to measure a wound stoma, a pressure injury or the like, the vertex angle of the notch 4 (i.e. the intersection point of the x measuring edge 2 and the y measuring edge 3) is placed at the corner of the target to be measured, and the outer ends of the tape measure one 10 and the tape measure two 11 are respectively drawn out, so that the two-dimensional size of the target to be measured, i.e. the length and the width, can be measured. The overall structure is simple, the operation is simple, and the ruler is easy to carry.

[0024] In addition, the outer edge of the main body part of the shell 1 outside the notch 4 is designed in an arc shape, the overall shape is more round, and the ruler is easier to carry.

[0025] In the above embodiment, the measured x direction size = the length of the x measuring edge 2 + the reading of the tape measure one 10 (with the 0 scale as the measurement reference of the conventional tape measure); and the measured y direction size = the length of the y measuring edge 3 + the reading of the tape measure two 11 (with the 0 scale as the measurement reference of the conventional tape measure).

[0026] In order to more intuitively and quickly obtain the measured two-dimensional size, in a preferred embodiment of the utility model, the length of the x measuring edge 2 is a, and the measurement scale of the tape measure one 10 starts from a, for example Figure 1 as shown in the figure, the length of the x measuring edge 2 is 2cm, and the tape measure one 10 takes 2cm as the starting scale of the measurement scale, instead of the starting scale of the 0 scale of the prior art. Similarly, the length of the y measuring edge 3 is b, and the measurement starting value of the tape measure two 11 is b, for example Figure 1As shown, the length of the y measuring edge 3 is 2 cm, and the tape 2 11 takes 2 cm as the starting scale of the measuring mark, instead of taking 0 as the starting scale in the prior art. Thus, the two-tape scale reading can directly obtain the measured two-dimensional size. In addition, the back scale of the two tapes can be designed to still take 0 as the starting scale, so as to measure the arm circumference, leg circumference and the like.

[0027] On the basis of the above-mentioned embodiments, a preferred embodiment of the utility model further includes a measuring rope 8 wound in the shell 1, which has the same principle as the soft tape in the prior art, and the shell is the shell 1, and the difference is that the wound rope replaces the soft ruler part in the soft tape, and the shell 1 has a button outside for retracting the measuring rope 8; the shell 1 has a third opening 7 corresponding to the measuring rope 8 on the outer wall, and the outer end of the measuring rope 8 extends out of the third opening 7. The outer end of the measuring rope 8 is provided with a pull buckle (81) for keeping the outer end of the measuring rope 8 on the outside of the shell 1. The shell 1 is further provided with a scale line 12 along the outer edge of the outer wall, and the starting point of the scale line is located at the third opening 7. Its role is that the stretched measuring rope 8 can be used to measure irregular-shaped objects, such as the length of irregular pipes, irregular wounds and the like. The method is to take the circumference of the irregular pipe as an example, first pull out the measuring rope 8 to measure the circumference of the pipe, and then measure the length of the rope close to the scale line 12 to obtain the measured size.

[0028] On the basis of the above-mentioned embodiments, a preferred embodiment of the utility model further includes a pupil size contrast sample 9 for contrasting the size of the patient's pupil. In an embodiment, the pupil size contrast sample 9 is arranged on the shell 1, specifically a plurality of black circular patterns, as shown in Figure 1 In another embodiment, the pupil size contrast sample 9 is arranged on any tape, specifically on the back of the tape, for example, on the back of the second tape, as shown in Figure 2 On the opposite side of the numerical scale mark line, a series of black semicircles (the diameter is close to the edge of the tape main body) with increasing radius are arranged along the edge, which is more convenient for comparison and measurement. For the above-mentioned black circles or black semicircles, the pupil size contrast sample 9 is arranged in multiple, and arranged in order from large to small, and the diameters are designed as 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm (the size of the black circle or semicircle is based on the fact that the human pupil fluctuates between 1-8 mm, and the record is accurate to 0.5 mm).
