[0002] Waist circumference is one of the important reference indicators for observing the treatment effect of obesity, diastasis recti, and weight management patients. According to the "Guidelines for Primary Care Diagnosis and Treatment of Obesity (2024)": Waist circumference is used to diagnose central obesity: measuring waist circumference can diagnose central obesity and peripheral obesity; waist circumference measurement method: the subject stands with relaxed shoulders and abdomen, breathing steadily, feet 35-30cm apart, and uses a tape measure to measure around the abdomen at the midpoint of the line connecting the anterior superior iliac spine and the lower edge of the 12th rib on the mid-axillary line.

[0003] Measure the body circumference at the horizontal position of the midpoint of the line connecting the lower edge of the costal arch and the iliac crest.

[0004] In existing technologies, a soft measuring tape is usually used to measure waist circumference. However, during the measurement process, not only is it difficult to quickly determine the measurement position, resulting in inaccurate position and affecting measurement efficiency, but the soft measuring tape can also shift vertically, leading to inaccurate measurement values.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-4A waist circumference measuring device includes a measuring tape 2 and a connecting piece 1, preferably made of medical-grade plastic. The connecting piece 1 has a positioning hole 101 corresponding to the navel, the diameter of which is larger than that of an adult's navel. One end of the measuring tape 2 is detachably connected to one side of the connecting piece 1. Preferably, one end of the measuring tape 2 is fixed to the connecting piece 1 with a screw, ensuring reliable fixation, easy assembly and disassembly, and convenient replacement of the measuring tape 2, thus improving usability. The vertical distance between the axis of the measuring tape 2 and the positioning hole 101 is 1 cm, meaning that the distance between the center point of the measuring tape 2 and the positioning hole 101 in a frontal projection is 1 cm. Preferably, the measuring tape 2 is positioned above the positioning hole 101, allowing for quick positioning of the connecting piece 1 and improving measurement speed. Two sets of binding parts for fixing the connecting piece 1 to the abdomen of the person being measured are fixedly installed at the bottom and top of the connecting piece 1, respectively. At least one positioning plate 4 is slidably arranged between the two sets of binding parts. Preferably, two positioning plates 4 are provided, located on both sides of the connecting piece 1. During use, the two positioning plates 4 can be positioned at the mid-axillary line on both sides of the person being measured, which improves the limiting and guiding effect on the measuring tape 2. Positioning grooves 402 are provided on the positioning plates 4, which are open and facing outwards, facilitating the insertion of the measuring tape 2 through the positioning grooves 402. The other end of the measuring tape 2 is also inserted through the positioning grooves 402. During use, the connecting piece 1 is placed on the abdomen of the person being measured, allowing the measuring tape 2 to be positioned... Position hole 101 is located at the navel of the person being measured. Then, the connecting piece 1 is tied to the abdomen of the person being measured through the binding part. At this time, the positions of the two positioning plates 4 are adjusted so that they are located on both sides of the person being measured. Then, the free end of the measuring tape 2 is wrapped around the body circumference of the person being measured and passes through the positioning groove 402 in sequence. At this time, the free end of the measuring tape 2 is pulled around the body circumference of the person being measured to the joint end of the measuring tape 2 and the connecting piece 1, which is the measurement starting line. The reading on the measuring tape 2 can be read, and the waist circumference of the person being measured can be measured.

[0028] In use, by fixing one end of the measuring tape 2 to the connecting piece 1, and the positioning hole 101 corresponding to the navel is opened on the connecting piece 1, the measurement position can be quickly and accurately determined. In addition, a fixing strap 3 is set on the connecting piece 1, and a positioning plate 4 is slidably set between the upper and lower sets of fixing straps 3. A positioning groove 402 for limiting the measuring tape 2 is opened on the positioning plate 4, which can reduce the occurrence of the measuring tape 2 tilting up and down and improve the measurement accuracy.

[0029] Reference Figures 1-3Here, we design the binding part as two fixing straps 3. A limiting groove 102 is opened in the connecting piece 1. A fixing plate 301 is raised and lowered in the limiting groove 102. The two fixing straps 3 are fixed at both ends of the fixing plate 301 respectively. The free ends of the two fixing straps 3 are connected by Velcro. In use, by fixing two sets of fixing straps 3 distributed vertically on the connecting piece 1, the body circumference below and above the navel of the person being measured can be bound separately. This is not only suitable for people of different body types, but also increases the fixing effect of the connecting piece 1 and improves the user experience.

[0030] Reference Figure 4 A limiting block 302 is fixedly installed on a section of the fixing plate 301 located within the limiting groove 102. The width of the limiting block 302 is greater than the width of the fixing plate 301. During use, this prevents the limiting block 302 from being pulled out of the limiting groove 102, thus affecting normal use. Multiple sets of equidistant slots 103 are provided on the inner wall of the limiting groove 102. There are two to twenty sets of slots 103, preferably nine sets, and these nine sets are arranged vertically. An arc-shaped elastic sheet 303 is fixedly installed on the end face of the limiting block 302 near the slot 103. The top of the elastic piece 303 engages with the slot 103 at the current position. During use, a limiting block 302 is fixedly installed on the fixed plate 301, and a slot 103 is provided on the limiting groove 102. An elastic piece 303 is fixedly installed on the limiting block 302. By pushing the fixed plate 301 up and down along the limiting groove 102, the position of the fixing band 3 can be adjusted. After the adjustment is completed, the elastic piece 303 engages with the slot 103 at the current position, which can reduce the phenomenon of the fixed plate 301 automatically sliding up and down and improve the use effect.

[0031] In addition, a scale line extending along the height direction is fixedly provided on the outer end face of the limiting groove 102. During use, by fixing the scale line on the outer end face of the limiting groove 102, the position of the fixing plate 301 can be precisely adjusted, thereby improving the performance.

[0032] Reference Figures 1-3 Slide grooves 401 are provided at both ends of the positioning plate 4. The two sets of fixing straps 3 are slidably set in the corresponding slide grooves 401. In use, by providing slide grooves 401 on the positioning plate 4, it is convenient to adjust the position of the positioning plate 4 relative to the connecting piece 1, thereby improving the use effect.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
