Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a novel measuring tool. Background Technology
[0002] Breast cancer has become the most common malignant tumor worldwide, seriously endangering the physical and mental health of many women. The incidence of limb dysfunction and / or lymphedema on the affected side after breast cancer surgery is as high as 15-54%, which seriously affects the quality of life of breast cancer patients during the recovery period. Long-term severe lymphedema may also lead to lymphatic vessel-related malignancies. Early detection is the key to the prevention and treatment of lymphedema, because stage 0-1 lymphedema is still reversible, while stage 2-3 lymphedema is extremely difficult to treat. However, the symptoms of stage 0-1 lymphedema are not obvious, and patients do not feel changes, so it is difficult to detect. By the time patients notice changes in edema in their arms, it has often progressed to stage 2 or higher lymphedema. Clinically, for rapid identification and judgment, upper limb circumference measurement is often used to quickly determine the severity of edema. It is necessary to measure the circumference of the healthy limb and compare it with that of the affected limb to determine whether lymphedema has occurred. Currently, the method for measuring lymphedema is the equal volume fluid measurement method, which requires large equipment. In addition, some patients have PICC lines in their arms, making it difficult for them to take measurements. There are also simple measuring rulers, which require assistance to take repeated measurements at multiple points on the arm. Most breast cancer patients are middle-aged or elderly. In addition, the high incidence of lymphedema is within 5 years after breast cancer surgery. By this time, the patient's treatment cycle has ended, and without the guidance of medical staff, it is even more difficult to observe changes in arm swelling. Therefore, we have introduced a new type of measurement tool. Utility Model Content
[0003] The main objective of this invention is to provide a novel measuring tool that can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A novel measuring tool includes a connecting strip 1, with a sliding groove 2 inside the connecting strip 1 and a connecting groove 3 at the front end of the connecting strip 1. Three adjustment mechanisms 4 are slidably connected in the sliding groove 2, and a measuring mechanism 5 is fixedly connected to the front end of each of the three adjustment mechanisms 4. A scale bar 6 is provided at the rear of the upper end of the connecting strip 1. L-shaped fixing strips 7 are fixedly connected to the left and right ends of the connecting strip 1, and Velcro straps 8 are fixedly connected to the front ends of the two L-shaped fixing strips 7.
[0029] In this embodiment, the measuring mechanism 5 includes a connecting cylinder 51, with a movable groove 52 inside the connecting cylinder 51. Four damping grooves 53 are formed on the inner wall of the movable groove 52. A spring 54 is fixedly connected to the rear wall of the movable groove 52. A movable block 55 is fixedly connected to the front end of the spring 54. Four damping blocks 56 are fixedly connected to the outer surface of the movable block 55. A movable rod 57 is fixedly connected to the front end of the movable block 55. A loop 58 is fixedly connected to the front end of the movable rod 57. A measuring ruler 59 is inserted and connected inside the loop 58. The outer surface of the movable block 55 is movably connected to the inner wall of the movable groove 52. The four damping blocks 56 are slidably connected to the four damping grooves 53 respectively. The movable rod 57 is inserted and movably connected to the movable groove 52.
[0030] The above scheme allows the measuring ruler 59 to be pressed tightly against the patient's arm skin by the force of the spring 54 inside the connecting cylinder 51, and the circumference can be measured along the true contour of the arm using the measuring ruler 59.
[0031] In this embodiment, the adjustment mechanism 4 includes a connecting block 41, a connecting post 42 fixedly connected to the middle of the rear end of the connecting block 41, a slider 43 fixedly connected to the rear end of the connecting post 42, an L-shaped fixing block 44 fixedly connected to the upper end of the connecting block 41, a locking screw 45 threadedly connected to the upper end of the L-shaped fixing block 44, a pointer bar 46 fixedly connected to the rear end of the L-shaped fixing block 44, a connecting cylinder 51 fixedly connected to the front end of the connecting block 41, a slider 43 slidably connected to the slide groove 2, a connecting post 42 inserted into the connecting groove 3, and the end of the locking screw 45 tightly fitted to the connecting bar 1.
[0032] The above scheme allows for more precise measurement by having the slider 43 slide inside the groove 2 and the pointer bar 46 correspond to the scale bar 6 to control the sliding distance. The locking screw 45 is used to lock the position, making it easier to find suitable measurement points.
[0033] It should be noted that this utility model is a novel measuring tool. During use, two Velcro straps 8 are used to securely fix the entire measuring device to the patient's arm, ensuring that the connecting strip 1 is located on the side of the arm. At this time, the slider 43 can slide flexibly inside the connecting strip 1, driving the pointer strip 46 to align with the scale strip 6, thereby achieving precise control of the sliding distance. Once a suitable measuring position is found, the locking screw 45 will play its role, locking the slider 43, thus ensuring the accuracy of the measuring point. Considering the natural curve shape of the patient's arm, the spring 54 built into the connecting cylinder 51 provides just the right amount of elasticity, allowing the measuring ruler 59 to fit closely to the skin surface of the arm. In this way, the measuring ruler 59 can measure the circumference along the true contour of the arm, improving the accuracy of the measurement. In addition, the tool is equipped with three measuring mechanisms 5, which can simultaneously acquire data from three different measuring points. This not only facilitates the observation of changes in the swelling of the patient's arm but also simplifies the operation process, allowing one person to complete all the measurement work. In this way, other medical staff can use their valuable time to serve more patients, improving work efficiency.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
