Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a movable measuring ruler for quantifying vulvar lymphedema in patients with gynecological malignant tumors. Background Art

[0002] Gynecological malignancies seriously endanger women's health and survival. Lymphedema is a serious complication of surgical treatment. Previous studies have shown that the incidence of perineal lymphedema is highest in patients after cervical cancer surgery within six months. Severe vulvar edema not only affects the patient's walking, but also causes serious harm to the patient's urination function.

[0003] Currently, domestic and international guidelines recommend the use of conservative treatment for vulvar lymphedema. In previous conservative treatments, the degree of swelling of vulvar lymphedema is generally evaluated based on subjective assessments such as the softness, texture, and fibrosis of the vulvar skin. Existing tumor measuring rulers, such as those shown in Chinese application No. 201720391573.0: A measuring ruler for subcutaneous tumors, are provided with a first measuring part and a second measuring part that cooperate with each other, allowing tumor measurement to be performed using the principle of a vernier caliper.

[0004] The existing technology has the following problems: since the shape of tumor tissue is mostly circular or elliptical, the coordination between the first measuring part and the second measuring part in the above application is actually a direct measurement of the tumor using a ruler, which will produce a large deviation and make it difficult to accurately evaluate the treatment effect of vulvar lymphedema, so there is room for improvement. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the present invention provides a movable measuring ruler for quantifying vulvar lymphedema in patients with gynecological malignancies, so as to solve the technical problem that existing tumor measuring rulers use a straight ruler to measure tumors and are difficult to accurately assess tumor size.

[0006] The utility model is achieved through the following technical solutions:

[0007] A movable measuring ruler for quantifying vulvar lymphedema in patients with gynecological malignancies includes a main ruler and a slider. The main ruler is a flat rectangular parallelepiped with a first scale line provided on one side of the main ruler. The slider includes a first measuring portion, which is arc-shaped. The first scale line is used to indicate the reading of the first measuring portion.

[0008] Preferably, a rectangular scale window is provided on the main scale, the slider further includes a second measuring portion, the second measuring portion is linear, and the scale window is respectively provided with a second scale line and a third scale line on both sides along the length direction of the main scale, and the second scale line and the third scale line are both used to indicate the reading of the second measuring portion.

[0028] See also Figure 1-Figure 2A movable measuring ruler for quantifying vulvar lymphedema in patients with gynecological malignant tumors includes a main ruler 1 and a slider 2. The main ruler 1 is a flat rectangular parallelepiped. A first scale line 3 is set on one side of the main ruler 1. The slider 2 includes a first measuring part 21. The first measuring part 21 is arc-shaped. The first scale line 3 is used to indicate the reading of the first measuring part 21.

[0029] During use, the main ruler 1 is placed flat on the patient's vulva to be measured. The starting scale is aligned with the starting point of vulvar lymphedema, and the slider 2 is gently pushed until the maximum range of the edema area is reached. The value indicated by the slider 2 on the first scale line 3 is read; this value is the range of vulvar lymphedema. The main ruler 1 also measures the inter-iliac crest diameter (the distance between the outer edges of the anterior superior iliac crests on both sides) to determine the length of the patient's mons pubis, and the curved movable scale can help measure the width of the labia majora swelling. The curved structure of the first measuring section 21 quantitatively measures the difference in swelling between the two sides of the patient's labia majora, allowing the specific degree of vulvar lymphedema reduction to be determined after treatment. By comparing the before-and-after measurement data, the treatment effect of the patient's vulvar lymphedema can be quantitatively, accurately, and objectively evaluated.

[0030] In addition, due to the simple structure and low production cost of the measuring ruler, the procurement cost of medical institutions can be reduced, the coverage rate of the measuring ruler can be increased, and more medical institutions can use this measuring ruler for auxiliary diagnosis of patients; medical staff can operate this measuring ruler skillfully after simple training, which improves work efficiency, reduces operating errors, and is very convenient for monitoring patients in daily work; patients can also measure their lymphedema by themselves after simple training, and can measure their bodies by themselves while at home, which enhances patients' understanding and monitoring of their own condition, makes it easier for patients to understand the extent of their own disease, and improves patients' initiative and participation in treatment.

[0031] Preferably, the measuring ruler uses waterproof material, which can effectively prevent moisture from invading the interior of the measuring ruler, avoid the influence of moisture on the measuring ruler, and protect the measuring instrument from damage; the waterproof material can protect the structural stability of the measuring ruler, ensure that the measurement accuracy is not affected by external moisture, and improve the accuracy and reliability of the measurement; frequent contact with moisture may cause damage and aging of the measuring ruler. Choosing waterproof material can extend the service life of the measuring ruler and reduce maintenance and replacement costs.

[0032] To provide more measurement options and enhance the practicality and application value of the measuring ruler, in one embodiment, a rectangular scale window 4 is provided on the main ruler 1, and the slider 2 also includes a second measuring portion 22. The second measuring portion 22 is linear, and the scale window 4 is provided with second and third scale lines 5 and 6 on either side of the main ruler 1 along its length. The second and third scale lines 5 and 6 are used to indicate the reading on the second measuring portion 22. By designing the second measuring portion 22 and the rectangular scale window 4 on the measuring ruler, the measuring ruler can be used not only to measure the travel distance of vulvar lymphedema but also to measure the height of the swelling of the labia majora. This achieves a multifunctional measurement function, facilitating medical personnel's measurement needs in different situations. The multifunctional measurement design provides medical personnel with more measurement options, making the measuring ruler more flexible and diverse in clinical application, adapting to the measurement needs of different areas, and enhancing its practicality and application value.

[0033] In order to ensure the stability of the slider 2, in one embodiment, a limiting portion 7 is provided on the main scale 1, and the limiting portion 7 is used to prevent the slider 2 from falling off the main scale 1. By fixing the position of the slider 2 on the main scale 1 by the limiting portion 7, the stability of the slider 2 can be ensured, and the movement or shaking of the slider 2 during the measurement process can be avoided, resulting in inaccurate data; the design of the limiting portion 7 makes the measuring ruler easier to operate and more stable, thereby improving the user experience. During the measurement process, the user does not need to worry about the slider 2 falling off or being unstable, and can focus on the measurement operation, reducing operational errors and measurement inconveniences, and improving the convenience and efficiency of use. At the same time, the setting of the limiting block at the starting position of the first scale line 3 makes it convenient to align the measurement starting position with the scale line starting position during the measurement process, thereby improving the accuracy of the measurement.

[0034] To make the overall structure of the main ruler 1 more compact and concise, while also making it easier for medical personnel and patients to read during use, in one embodiment, the main ruler 1 includes a first measuring surface 11 and a second measuring surface 12. The first scale lines 3 are provided on the first measuring surface 11, and the second scale lines 5 and the third scale lines 6 are provided on the second measuring surface 12. The first scale lines 3 are provided solely on the first measuring surface 11, so that the first scale lines 3 fully cover the first measuring surface 11, ensuring full utilization of the space on the first measuring surface 11. This allows the first scale lines 3 to have a larger measurement range for main rulers 1 of the same specifications, meeting a wider range of measurement needs. The rational layout of the scale lines ensures clear distinctions between the scale lines, making it easier for medical personnel and patients to read during use. Furthermore, the overall structure of the main ruler 1 is made more compact and concise, making it easier for medical personnel and patients to carry the measuring ruler.

[0037] In order to help medical staff accurately measure and monitor swelling, in one embodiment, the range of the second scale line 5 is 5-50mm. The second scale line 5 is used to horizontally measure the width of the swelling of the labia majora of the vulva. The width of the swelling of the labia majora of the vulva is one of the important indicators of vulvar lymphedema in patients with malignant tumors. The range of the second scale line 5 is 5-50mm, which can help medical staff accurately measure and monitor swelling. By regularly measuring the width of the swelling of the labia majora of the vulva, changes in the degree of swelling can be understood, and abnormal conditions can be discovered and handled in a timely manner; by measuring the width of the swelling of the labia majora of the vulva, the medical team can evaluate the treatment effect. As the treatment progresses, the swelling width may improve or worsen. By comparing the measurement results at different time points, it can be determined whether the treatment effect is effective and the treatment plan can be adjusted in a timely manner.

[0038] In order to more comprehensively and accurately assess the swelling and help medical staff better understand the patient's condition, in one embodiment, the range of the third scale line 6 is 15-60mm. The third scale line 6 is used to horizontally measure the swelling height of the labia majora of the vulva. The comprehensive swelling of the labia majora of the vulva includes not only the width but also the height. The range of the third scale line 6 is 15-60mm and is used to measure the vertical swelling height of the labia majora of the vulva. By measuring the swelling height, the swelling can be more comprehensively and accurately assessed, helping medical staff better understand the patient's condition. The swelling height of the labia majora of the vulva may change over time or during the treatment process. By measuring the swelling height and recording the data, the changing trend of the swelling can be effectively tracked, abnormal conditions or treatment effects can be discovered in a timely manner, and the treatment plan can be adjusted.
