Problems solved by technology

[0003] First, the measured wound area is not accurate. In order to prevent contamination of the wound, the paper ruler cannot touch the wound, so the error is large
[0004] Second, due to the complex light in the medical environment, the color of the wound photos taken is easy to be distorted. Since the colors of different stages of wound healing are slightly different, distorted photos can easily lead to misjudgment of the wound healing status
[0005] 3. It is difficult to quantitatively judge whether the color of the photo is real
[0006] Fourth, ordinary rulers have a maximum scale, if the wound area is large, it cannot be measured

Embodiment 1

[0033] Such as figure 1 , figure 2 As shown, the multifunctional wound measuring ruler is a rectangular ruler 1, the scale 2 is marked on both long sides of the front of the ruler 1, one of the short sides of the front of the ruler 1 is a marking area 6, and the ruler 1 between the upper and lower rows of scale 2 The front area is respectively a standard color block 4 and an information column 5, and the ruler 1 has a paper slot 3 on the back.

[0034] Compared with ordinary rulers, this multi-functional wound measuring ruler provides more reference information for wound photos in the standard color block 4 and the information bar 5 area, and can be used alone or in combination through the paper slot 3, which can be directly and roughly The measured wound area can also accurately calculate the wound area in the later stage, and can also provide an important basis for the later processing of wound photos.

[0035] This measurement method can be widely used in the field of ta...

Embodiment 2

[0037] Ruler 1 is 17.8cm long and 2.8cm wide. On the left side of ruler 1 is a marking area 6 with a length and width of 2.8cm. On the right side of marking area 6, there is a scale 2 with a length of 15cm at the top and bottom of ruler 1, which is adjacent to the marking area. The 6 side is the 0 scale, and the right side of the ruler 1 is the 15 scale.

[0038] There are two paper slots 3 on the back of the ruler 1. The first slot is located at the left end of the ruler 0 scale, which is the back of the marking area 6. The direction of the first slot is perpendicular to the horizontal direction of the ruler, and is used for measuring common wounds. , directly insert another multifunctional wound measuring ruler into the slot to form a square, and directly measure the length and width of the wound, see image 3 . The second slot is located at the end of the largest scale of the ruler, and the direction of the socket is parallel to the horizontal direction of the ruler. I...

Embodiment 3

[0042] A digital photo is essentially composed of a matrix of pixels. Each pixel has a certain color that can be represented by an RGB value. In this way, as long as you know the area of ​​the object corresponding to the number of unit pixels, and then know the number of pixels occupied by the wound, you can calculate the area of ​​the wound.

[0043] The wound area measuring method of multifunctional wound measuring ruler of the present invention comprises the following steps:

[0044] a. Place ruler 1 next to the wound, and use a digital camera to take pictures;

[0045] b. Open the wound picture through the picture processing tool;

[0046] c. Select any standard color block 4, the number of pixels can be obtained, assume the number of pixels as x, the side length of the square standard color block is a, and then select the wound to be measured, and obtain the number of pixels again , we assume y, then the final area of ​​the wound is:

[0047] Z=y*(a*a) / x.

Abstract

The invention relates to a multi-functional cut measurement rule and a measurement method of the multi-functional cut measurement rule. The measurement rule at least comprises a rectangular rule (1), and is characterized in that two long edges at the front of the rule (1) are provided with scales (2), one short edge at the front of the rule (1) is a marking area (6), the front areas of the rule (1) between the scales (2) in the upper row and the scales (2) in the lower row include a standard color lump (4) and an information bar (5), and the back of the rule (1) is provided with a paper insertion groove (3). The measurement rule can be separately used and alternatively each two measurement rules can be combined for use. The measurement rule is easy to produce and low in cost; areas can be visually measured when a common cut is measured; on the condition that the areas of the cut is large or requirements for the areas of the cut are high, the areas of the cut can be obtained through calculation; and the color of the cut can be recovered through picture processing in a later stage and accordingly a precise reference is provided for medical staff.

Description

technical field [0001] The invention relates to the technical field of clinical wound assessment, in particular to a multifunctional wound measuring ruler for clinical wound assessment and a measuring method thereof. Background technique [0002] Clinical wound photos are an important basis for evaluating wounds. As a visual comparison of the wound area, many clinical medical staff will put a paper ruler next to the wound for comparison to calculate the wound area when taking pictures of the wound. But its disadvantages are: [0003] First, the measured wound area is inaccurate. In order to prevent contamination of the wound, the paper ruler cannot touch the wound, so the error is relatively large. [0004] Second, due to the complex light in the medical environment, the color of the wound photos taken is easy to be distorted. Since the colors of different stages of wound healing are slightly different, distorted photos can easily lead to misjudgment of the wound healing. ...
