Description

Technical Field

[0001] The present invention relates to medical devices, and specifically to a method for measuring the area of subcutaneous fat hyperplasia with multiple functions for medical use. Background Art

[0002] At present, after most patients inject insulin multiple times, it will cause subcutaneous fat tissue hyperplasia in the patients, resulting in a significant reduction in the absorption rate of insulin when the patients inject insulin subsequently, thus causing damage to the patients' bodies and increasing the patients' financial investment. The subcutaneous tissue is prone to hyperplasia, and the shapes of the subcutaneous tissue hyperplasia are mostly irregular. In current hospitals, generally, medical staff rely on conventional rulers to measure the subcutaneous tissue hyperplasia area as a regular figure and calculate the area. Calculated in this way, the error between the area and the actual value is very large, which is not conducive to the statistics of medical staff. Summary of the Invention

[0003] The technical problem to be solved by the present invention is, aiming at the above-mentioned shortcomings of the prior art, to propose a method for measuring the area of subcutaneous fat hyperplasia with multiple functions for medical use. The present invention can divide the subcutaneous tissue hyperplasia area of the patient into multiple small blocks and then measure the area of each small block. It is convenient to operate, safe and reliable, simple in structure, low in cost, convenient to measure and easy to calculate.

[0004] To solve the above technical problem, the technical solution of the present invention is realized in the following way: A measuring ruler includes an outer fixing ring, an inner fixing ring, multiple connecting rods and multiple sliders. One end of each connecting rod along the length direction is connected to the inner fixing ring, and the multiple connecting rods are evenly spaced along the circumferential direction. The outer fixing ring is connected to the other end of each connecting rod. The multiple sliders are respectively slidably arranged on the multiple connecting rods, and two sliders are arranged on each connecting rod;

[0005] A through groove is arranged at one end of each connecting rod along the length direction. Scales are arranged on the outer surface of each connecting rod at positions corresponding to both sides of the through groove. From the end of the connecting rod connected to the inner fixing ring to the end of the connecting rod connected to the outer fixing ring, the values of the scales on the connecting rod increase from small to large, and the graduation value of the scale is 1 mm;

[0006] A limit set screw for fixing the slider on the connecting rod is arranged on each slider.

[0007] According to the technical solution of the present invention, the subcutaneous hyperplasia area measuring ruler is set, which can be set to fit the skin hyperplasia area of the patient, and the sliders are slid so that each slider corresponds to the edge of the skin hyperplasia area of the patient, dividing the skin hyperplasia area of the patient into multiple fan-shaped or triangular areas, and calculating the area of each fan-shaped or triangular area through the scale values set on the connecting rod, and then adding up the areas of each fan-shaped or triangular area to obtain the area of the skin hyperplasia area of the patient, reducing the error and increasing the accuracy of the data.

[0008] In the technical solution of the present invention, a through groove is provided on the connecting rod, and the hyperplastic area of the patient's skin can be marked through the sliding groove.

[0009] The further limited technical solution of the present invention is:

[0010] On the upper surface of each connecting rod, trapezoidal track bosses are formed upward along both side edges, and sliding grooves are provided at both ends of each connecting rod along the length direction of the connecting rod; the trapezoidal track bosses are provided to facilitate the sliding of the slider.

[0011] A plurality of sliders are all made of transparent PVC plastic. Each slider is provided with a limiting boss that slidably cooperates with the trapezoidal track boss, and each slider is also provided with a sliding boss that slidably cooperates with the sliding groove. The sliding boss on the slider is embedded in the sliding groove of the connecting rod, and the limiting boss on the slider slidably cooperates with the trapezoidal track boss on the connecting rod; through the cooperation of the trapezoidal track boss and the limiting boss, and the cooperation of the sliding groove and the sliding boss, the slider always slides along the connecting rod, with a simple structure, cost saving, and convenient operation.

[0012] The through groove and the sliding groove on each connecting rod penetrate through one end of the connecting rod connected to the inner fixing ring, which is convenient for installing the slider on the connecting rod, simplifies the structure, and saves costs.

[0013] Both the outer fixing ring and the inner fixing ring are made of transparent PVC plastic; the overall weight is reduced and the cost is saved.

[0014] The present invention also discloses a method for using the device, including the following steps:

[0015] Step 1: Preparation:

[0016] Medical staff set the device to fit the subcutaneous fat hyperplastic area of the patient, and the inner fixing ring is at the visual center of the subcutaneous hyperplastic area of the patient. Loosen all the limiting set screws so that all the sliders can slide freely. Define the figure formed by the cooperation of two adjacent sliders on each two adjacent connecting rods and close to each other as a sub-block of the subcutaneous hyperplastic area of the patient, and the sum of the areas of all sub-blocks is the total area of the subcutaneous hyperplastic area of the patient;

[0017] Step 2: Measurement:

[0018] Medical staff slide each slider so that each slider is at the edge of the subcutaneous hyperplastic area of the patient, tighten all the limiting set screws to fix all the sliders, and then medical staff record the scale values of each slider on the corresponding connecting rod;

[0019] Step 3: Judgment and calculation:

[0020] Define the number of connecting rods as x. If the absolute value of the difference in the scale values on the connecting rods corresponding to the two sliders of a certain sub-block is greater than or equal to 0 mm and less than or equal to 3 mm, then regard this sub-block as a sector. Define the radius of the sector sub-block as r. Then the middle value of the scale values on the connecting rod 3 corresponding to the two sliders of this sub-block is the radius r of this sector sub-block. The calculation formula for the area s of the current sub-block is: s = (π × r²) / x;

[0021] If the absolute value of the difference in the scale values on the connecting rods corresponding to the two sliders of a certain sub-block is greater than 3 mm, then regard this sub-block as a triangle. Define the two side lengths of the triangle sub-block as i and m. Take the larger scale value as the base i of the triangle and the smaller scale value as the hypotenuse m of the triangle. Then the calculation formula for the area s of the current sub-block is: s = m × Sin(2π / x) × i × (1 / 2).

[0022] The beneficial effects of the present invention are as follows: Through the technical solution of the present invention, the subcutaneous hyperplasia area measuring ruler is set, which can be set to fit the skin hyperplasia area of the patient. By sliding the sliders, each slider corresponds to the edge of the skin hyperplasia area of the patient, dividing the skin hyperplasia area of the patient into multiple fan-shaped or triangular areas, and calculating the area of each fan-shaped or triangular area through the scale values set on the connecting rods, and then adding up the areas of each fan-shaped or triangular area, the area of the skin hyperplasia area of the patient can be obtained, reducing errors and increasing the accuracy of the data; a through groove is provided on the connecting rod, and the skin hyperplasia area of the patient can be marked through the sliding groove.

[0031] Embodiment 1

[0032] As Figure 1 shown, a method for measuring the area of medical multifunctional subcutaneous fat hyperplasia includes an outer fixing ring 1, an inner fixing ring 2, multiple connecting rods 3 and multiple sliders 4. One end of each connecting rod 3 along the length direction is connected to the inner fixing ring 2. Each connecting rod 3 is embedded in the inner fixing ring 2, and the multiple connecting rods 3 are evenly spaced along the circumferential direction. The outer fixing ring 1 is connected to the other end of each connecting rod 3 by bolts. The inner fixing ring 2 is arranged in a fitting manner corresponding to the visual center position of the skin hyperplasia area of the patient. The multiple sliders 4 are respectively slidably arranged on the multiple connecting rods 3, and two sliders 4 are arranged on each connecting rod 3. Preferably, 12 connecting rods 3 are arranged, and preferably 24 sliders 4 are arranged. Slide the sliders 4 so that each slider 4 is on the side line of the skin hyperplasia area of the patient. Define the sector or triangle formed by the cooperation of two adjacent and mutually close sliders 4 on each two adjacent connecting rods 3 as a sub-block of the patient's subcutaneous hyperplasia area. The sum of the areas of all sub-blocks is the total area of the patient's subcutaneous hyperplasia area.

[0033] One end of each connecting rod 3 is provided with a through groove 3a along the length direction. Through the through groove 3a, markings can be made on the patient's skin surface at the marked area of the patient's skin hyperplasia region; on the outer surface of each connecting rod 3, scales are provided at positions corresponding to both sides of the through groove 3a. From the end where the connecting rod 3 is connected to the inner fixing ring 2 to the end where the connecting rod 3 is connected to the outer fixing ring 1, the values of the scales on the connecting rod 3 increase from small to large, and the graduation value of the scale is 1 mm, providing data for calculating the area of the sub-blocks. The scale value corresponding to the slider 4 on the connecting rod 3 is the radius r of the fan-shaped sub-block or the two side lengths i, m of the triangular sub-block;

[0034] A limit set screw 4c for fixing the slider 4 on the connecting rod 3 is provided on each slider 4. Tighten the limit set screw 4c to fix the position of the slider 4.

[0035] As Figure 3 shown, on the upper surface of each connecting rod 3, trapezoidal track bosses 3b are formed upward along both side edges, and on both ends of each connecting rod 3, chutes 3c are provided along the length direction of the connecting rod 3;

[0036] As Figure 3 shown, multiple sliders 4 are all made of transparent PVC plastic. Each slider 4 is provided with a limit boss 4a that slidably cooperates with the trapezoidal track boss 3b, and each slider 4 is also provided with a sliding boss 4b that slidably cooperates with the chute 3c. The sliding boss 4b on the slider 4 is embedded in the chute 3c of the connecting rod 3, and the limit boss 4a on the slider 4 slidably cooperates with the trapezoidal track boss 3b on the connecting rod 3. Through the cooperation of the trapezoidal track boss 3b and the limit boss 4a, and the cooperation of the chute 3c and the sliding boss 4b, the slider 4 always slides along the connecting rod 3.

[0037] The through groove 3a and the chute 3c on each connecting rod 3 penetrate through the end where the connecting rod 3 is connected to the inner fixing ring 2, facilitating the installation of the slider 4 onto the connecting rod 3.

[0038] The outer fixing ring 1 and the inner fixing ring 2 are both made of transparent PVC plastic.

[0039] The usage method of this device includes the following steps:

[0040] Step 1: Preparation:

[0041] Medical staff set this device to fit the subcutaneous fat hyperplasia region of the patient, and the inner fixing ring 2 is at the visual center position of the patient's subcutaneous hyperplasia region. Loosen all the limit set screws 4c so that all the sliders 4 can slide freely. Define the figure formed by the cooperation of two adjacent sliders 4 on each two adjacent connecting rods 3 as a sub-block of the patient's subcutaneous hyperplasia region. The sum of the areas of all the sub-blocks is the total area of the patient's subcutaneous hyperplasia region;

[0042] Step 2: Measurement:

[0043] Medical staff slide each slider 4 so that each slider 4 is at the edge of the subcutaneous hyperplastic area of the patient, tighten all the limit set screws 4c to fix all the sliders 4, and then the medical staff record the scale values of each slider 4 on the corresponding connecting rod 3;

[0044] Step 3: Judge and calculate:

[0045] Define the number of connecting rods 3 as x. If the absolute value of the difference between the scale values of the connecting rods 3 corresponding to the two sliders 4 of a certain sub-block is greater than or equal to 0 mm and less than or equal to 3 mm, then regard this sub-block as a sector. Define the radius of the sector sub-block as r. Then the middle value of the scale values of the connecting rods 3 corresponding to the two sliders 4 of this sub-block is the radius r of this sector sub-block. The calculation formula for the area s of the current sub-block is: s = (π×r²) / x;

[0046] If the absolute value of the difference between the scale values of the connecting rods 3 corresponding to the two sliders 4 of a certain sub-block is greater than 3 mm, then regard this sub-block as a triangle. Define the two side lengths of the triangle sub-block as i and m. Take the larger scale value as the base i of the triangle and the smaller scale value as the hypotenuse m of the triangle. Then the calculation formula for the area s of the current sub-block is: s = m×Sin(2π / x)×i×(1 / 2).

[0047] The usage process of this embodiment is as follows:

[0048] When it is necessary to measure the area of the subcutaneous hyperplastic area of the patient, the medical staff set the body of this embodiment against the subcutaneous hyperplastic area of the patient, and the inner fixing ring 2 is at the visual center position of the subcutaneous hyperplastic area of the patient. Loosen all the limit set screws 4c to make all the sliders 4 slide freely. Slide each slider 4 so that each slider 4 is at the edge of the subcutaneous hyperplastic area of the patient, tighten all the limit set screws 4c to fix all the sliders 4, and then the medical staff record the scale values of each slider 4 on the corresponding connecting rod 3 and calculate the area of each sub-block;

[0049] The calculation process of the sub-block area is as follows:

[0050] The medical staff observe the scale values of the connecting rods 3 corresponding to the two sliders 4 at both ends of each elastic band 5. If the absolute value of the difference between the scale values of the connecting rods 3 corresponding to the two sliders 4 of a certain sub-block is greater than 0 mm and less than 3 mm, then regard this sub-block as a sector. Then the middle value of the scale values of the connecting rods 3 corresponding to the two sliders 4 of this sub-block is the radius r of this sector sub-block. The calculation formula for the area s of the current sub-block is: s = (π×r²) / x;

[0051] If the absolute value of the difference between the scale values on the connecting rods 3 corresponding to the two sliders 4 of a certain sub-block is greater than 3 mm, then this sub-block is regarded as a triangle, with the larger scale value as the base i of the triangle and the smaller scale value as the hypotenuse m of the triangle. The calculation formula for the area s of the current sub-block is: s = m × Sin(2π / x) × i × (1 / 2).

[0052] Then add up the area values of each sub-block, and the obtained value is the total area of the subcutaneous hyperplasia region of the patient.

[0053] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
