[0023] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative work shall fall within the protection scope of the utility model.

[0024] Refer to Figure 1 、 Figure 3 、 Figure 4, An embodiment provided by the present utility model: a movable upper limb arm circumference positioning measuring instrument, including an upper limb scale 1. The upper limb scale 1 is in a long strip shape as a whole, similar to a ruler in shape, and is made of lightweight and strong aluminum alloy material, making the upper limb scale 1 convenient to operate and carry, and ensuring stability during the measurement process. A wrist fixing band 4 is fixedly connected inside the upper limb scale 1. The wrist fixing band 4 is a flat strip-shaped structure, made of soft, elastic and skin-friendly nylon material. An armpit fixing band 12 is fixedly connected inside the upper limb scale 1. The armpit fixing band 12 is also a strip-shaped structure, wider than the wrist fixing band 4, and its material is breathable and wear-resistant cotton material. A sliding measurement component is slidably connected to the outside of the upper limb scale 1. The measurement component can freely slide along the long side direction of the upper limb scale 1, and its sliding track is a straight line, and the sliding process is stable and smooth to ensure accurate measurement at different positions;

[0025] The measurement component fixedly connected includes a movable positioning bottom plate 7. The movable positioning bottom plate 7 is a rectangular thin plate-shaped structure, made of engineering plastic with a certain strength. The inside of the movable positioning bottom plate 7 is slidably connected to the outside of the upper limb scale 1. A fixing hole 8 is provided inside the movable positioning bottom plate 7. The fixing hole 8 is a circular hole-shaped structure with a suitable diameter, which can be used to insert a positioning pin. Two measurement positioning lines 9 are provided on the outside of the movable positioning bottom plate 7. A plurality of measurement soft rulers 10 are fixedly connected to the bottom of the measurement component. The measurement soft rulers 10 are long strip-shaped soft materials, usually made of soft, elastic and clearly marked polyvinyl chloride material, for measuring around the upper limb, and the measurement soft rulers 10 can bend along with the shape of the upper limb to fit the contour of the upper limb for accurate measurement. A plurality of marking lines 11 are provided on the outside of the measurement soft rulers 10. The marking lines 11 are short straight-line marks, printed with clear and wear-resistant ink;

[0026] Refer to Figure 2 , Figure 4, there are multiple scale lines 2 on the outside of the upper limb ruler 1. The scale lines 2 are thin linear marks printed with fade-resistant ink. There are two wrist transverse crease positioning lines 3 on the outside of the upper limb ruler 1. The wrist transverse crease positioning lines 3 are horizontal linear marks, also printed with ink, which are used to assist in positioning the position of the wrist transverse crease during measurement so as to determine the starting point of measurement. There is a fixing magic tape one 5 fixedly connected to the outside of the wrist fixing strap 4. The fixing magic tape one 5 is the hook surface part in the common magic tape structure, composed of small plastic hook-shaped structures, and its color is coordinated with the wrist fixing strap 4. Its main function is to cooperate with the fixing magic tape two 6 to realize the fixing function of the wrist fixing strap 4. There is a fixing magic tape two 6 fixedly connected to the outside of the wrist fixing strap 4. The fixing magic tape two 6 is the hair surface part in the magic tape structure, composed of a soft fiber structure. The outside of the armpit fixing strap 12 is fixedly connected to the outside of the fixing magic tape one 5, and the outside of the armpit fixing strap 12 is fixedly connected to the outside of the fixing magic tape two 6.

[0027] Working principle: First, the operator places the upper limb ruler 1 on the surface of the upper limb and firmly fixes it through the wrist fixing strap 4 and the armpit fixing strap 12 to ensure the stability of the device during measurement. The fixing straps are made of soft and elastic materials, which can comfortably fit the skin and avoid discomfort to the user.

[0028] Next, the operator adjusts the measuring component as needed. This component can freely slide in the long side direction of the upper limb ruler 1 to ensure a smooth measurement process. There are multiple measuring flexible rulers 10 connected to the bottom of the measuring component. These flexible rulers are made of soft polyvinyl chloride material and can flexibly bend to adapt to the shape of the upper limb, so as to achieve accurate circumferential measurement. During the measurement process, the operator can assist in positioning through the scale lines 2 and the wrist transverse crease positioning lines 3 on the upper limb ruler 1 to ensure that the starting point of measurement is accurate. The multiple marking lines 11 on the measuring flexible ruler 10 provide clear measurement references for the operator to read data conveniently. After the measurement is completed, the measuring component can be easily slid to a new position for repeated measurement, and the whole process is efficient and easy to operate. Through this series of steps, this measuring instrument can achieve rapid and accurate measurement of the upper limb circumference and meet the needs of clinical and research.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
