DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the drawings. Among them, the drawings form a part of the present utility model and are used together with the embodiments of the present utility model to explain the principle of the present utility model, rather than to limit the scope of the present utility model.

[0031] Embodiment 1

[0032] A specific embodiment of the present utility model, such as Figure 1 、 Figure 2As shown in the figure, the utility model provides a leg circumference measuring tool, which includes a positioning member 1, a measuring member 2 and a supporting member 3. The positioning member 1 can locate the midpoint of the patella and the positions 15 cm above and 10 cm below the midpoint of the patella, so that the measuring member 2 can accurately locate at the leg measurement position. The supporting member 3 can support the patient's leg, making the leg measurement part suspended above the bed surface. When measuring the leg circumference of bedridden, paralyzed and people with muscle strength below grade V, using the leg circumference measuring tool of this embodiment, a nurse can conveniently and standardly complete the measurement alone without the help of others, which is accurate and labor-saving.

[0033] Specifically, the positioning member 1 includes a first positioning member 11 and a second positioning member 12. The first positioning member 11 is used to locate the position in front of the leg, including a patella positioning part 111 and a first limiting band 112. The patella positioning part 111 is used to locate the center point of the patella, and the first limiting band 112 is used to locate the leg measurement positions 15 cm above and 10 cm below the midpoint of the patella. The patella positioning part 111 is a sheet body with a hollow structure, and a positioning ring 1111 is provided at the center of the sheet body. When the positioning ring 1111 is at the midpoint of the patella, the sheet body with a hollow structure can fit on the knee surfaces of different sizes and shapes, so that the positioning ring 1111 is stably located at the midpoint of the patella and is not easy to shift, so as to ensure the accuracy of the next test point positioning. Preferably, the hollow structure of the patella positioning part is composed of more than 1 ring body. The ring body is located outside the positioning ring 1111 and is concentric with the center of the positioning ring 1111. The diameters of the positioning ring 1111 and the multiple ring bodies increase in sequence, forming a sheet body with a target ring-shaped hollow structure, so that the patella positioning part 111 can easily and flexibly fit on the patella surface of the knee part, realizing a stable positioning of the midpoint of the patella.

[0034] In order to accurately locate the leg measurement positions 15 cm above and 10 cm below the midpoint of the patella, the positioning ring 1111 is arranged on the first limiting band 112. The distances from the center of the positioning ring 1111 to both ends of the first limiting band 112 are 15 cm and 10 cm respectively; both ends of the first limiting band 112 are connected to two measuring rulers 21, and the two measuring rulers 21 are perpendicular to the first limiting band 112. When the positioning ring 1111 completes the positioning of the midpoint of the patella, by straightening the first limiting band 112, the two measuring rulers 21 can be accurately positioned at the positions 15 cm above and 10 cm below the midpoint of the patella, and the leg circumference measurement of the two positions can be conveniently and quickly completed at one time.

[0035] Considering that it is easy for the measuring ruler 21 to deviate from the center line of the leg during the measurement around the leg, which affects the measurement accuracy, the leg circumference measuring tool of this embodiment is also provided with a second positioning member 12. The second positioning member 12 includes a popliteal fossa positioning portion 121 and a second limiting band 122. The second limiting band 122 includes a limiting section 1221. The limiting section 1221 is arranged parallel to the first limiting band 11 and has the same length. The two ends of the limiting section 1221 are also respectively connected to the two measuring rulers. The popliteal fossa positioning portion 121 is located on the limiting section 1221. The position of the popliteal fossa positioning portion 121 on the limiting section 1221 corresponds to the position of the positioning ring 1111 on the first limiting band 112. Thus, the distances between the two measuring rulers are also 10 cm and 15 cm respectively. The two measuring rulers 21 can also perform two-point positioning by straightening the limiting section 1221, thereby preventing the measuring ruler 21 from deviating during the measurement around the leg and ensuring the accuracy of the measured value. Preferably, the popliteal fossa positioning portion 121 is a semi-elliptical spherical shell, and the concave surface of the shell is located on the scale side of the measuring ruler 21 to facilitate positioning by fitting the popliteal fossa through finger touch.

[0036] Since the leg circumferences of patients are different, in order to enable the positioning ring 1111 and the popliteal fossa positioning portion 121 to always accurately position at the midpoint of the patella and the popliteal fossa respectively, and the measuring ruler 21 between the first limiting band 112 and the limiting section 1221 does not bend or fold, the distance between the two ends of the first limiting band 112 and the limiting section 1221 on the same measuring ruler 21 is adjustable. Preferably, sliding sleeves 1121 are provided at both ends of the first limiting band 112, and the two measuring rulers 21 are respectively inserted into the two sliding sleeves 1121.

[0037] In order to facilitate the measurement of patients who cannot lift their lower limbs by themselves, the leg circumference measuring tool of this embodiment is specifically provided with a support member 3. The support member 3 includes a first support pad 31 and a second support pad 32. The first support pad 31 and the second support pad 32 are respectively fixed at both ends of the second positioning member 12, and can lift the lower limb of the patient, making the measurement areas on both sides of the popliteal fossa suspended, so as to facilitate the measurement operation and obtain accurate leg circumference data. Among them, the first support pad 31 is located on the side where the distance between the popliteal fossa positioning portion 121 and the measuring ruler 21 is 10 cm, and is used to support the lower leg. The second support pad 32 is located on the side where the distance between the popliteal fossa positioning portion 121 and the measuring ruler 21 is 15 cm, and is used to support the thigh.

[0038] Optionally, the first support pad 31 and the second support pad 32 are arc-shaped soft pads. The opposite sides of the two arc-shaped soft pads are higher, so as to suspend the leg between them from the bed surface. The other sides of the two arc-shaped soft pads have slopes, so as to provide a large-area stable support for the leg and improve the comfort of the patient's leg.

[0039] The usage method of the leg circumference measuring tool in this embodiment is as follows: First, unfold the measuring tool, make the graduated side of the measuring ruler 21 fit with the bed surface, lift the lower leg and place the first support pad 31 under the lower leg, then place the second support pad 32 under the thigh. Hold the concave surface of the popliteal fossa positioning part 121 with fingers and make the popliteal fossa positioning part 121 fit with the popliteal fossa. At the same time, place the patella positioning part 111 on the knee, and place the positioning ring 1111 at the midpoint of the patella to complete the positioning of the midpoint of the patella and the popliteal fossa. Then, push the first support pad 31 and the second support pad 32 to both sides respectively until the second limiting band 122 is straightened, so that the two measuring rulers 21 are respectively positioned at the measuring positions 15 cm above and 10 cm below the midpoint of the patella, and at the same time make the part of the leg to be measured hang in the air and leave the bed surface. Then, measure around the leg with the two measuring rulers 21 in turn. When measuring, pay attention to adjusting the position of the sliding sleeve 1121 on the measuring ruler 21 to ensure that the two measuring rulers 21 between the first limiting band 112 and the second limiting band 122 are fully stretched. Finally, record the measurement data to complete the measurement. The whole process is labor-saving and convenient. One person can easily complete the leg circumference measurement of patients with limb paralysis, and the positioning is convenient and accurate, the process is standardized, and the measurement result is accurate and reliable.

[0040] Preferably, the leg circumference measuring tool in this embodiment further includes a binding member 4 for binding the popliteal fossa positioning part 121 and the patella positioning part 111 to the knee. Optionally, the binding member 4 is a strip-shaped band, which is fixedly connected in a cross shape with the second limiting band 122, and the cross point is at the popliteal fossa positioning part 121. Adhesive surface A 41 is arranged on both sides of the binding member 4, and adhesive surface B 1112 is arranged on both sides of the patella positioning part 111. After the patella positioning part 111 and the popliteal fossa positioning part 121 are both positioned, surround the binding member 4 from both sides of the popliteal fossa towards the knee, and after tightening, bond the adhesive surface A 41 and the adhesive surface B 1112 together to make the popliteal fossa positioning part 121 and the patella positioning part 111 achieve a stable positioning effect and improve the measurement accuracy.

[0041] Embodiment 2

[0042] The difference between the leg circumference measuring tool in this embodiment and that in Embodiment 1 is that the sizes of the first support pad 31 and the second support pad 32 are different, and the distances between the first support pad 31 and the second support pad 32 and the two measuring rulers 21 can be adjusted.

[0043] Specifically, as Figure 3 shown, when the first support pad 31 supports the lower leg, if the patient's foot is in a suspended state, it will be very unstable and cause discomfort. The shape of the first support pad 31 in this embodiment is a cuboid soft pad, and the length direction is the length direction of the second limiting band 122, that is, the length of the first support pad 31 is greater than the length of the second support pad 32, so that the first support pad 31 can support the foot while supporting the lower leg, which can not only improve the stability of the support but also increase the comfort of the patient.

[0044] Preferably, the thickness of the first support pad 31 is greater than that of the second support pad 32, so that when the leg is padded up, it is in a natural straight state and the force is evenly distributed.

[0045] Preferably, the second limiting band 122 further includes two adjusting sections 1222. One ends of the two adjusting sections 1222 are respectively connected to the two ends of the limiting section 1221, and the other ends are respectively connected to the first support pad 31 and the second support pad 32.

[0046] By providing two adjusting sections 1222, the distances between the first support pad 31 and the second support pad 32 and the two measuring rulers 21 can be adjusted. For legs of different lengths, the first support pad 31 and the second support pad 32 can be placed at the best support positions, improving the leg support effect, ensuring the safety and stability during the leg circumference measurement process, and guaranteeing the accuracy and reliability of the measurement results.

[0047] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
