Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lower limb circumference measurement technology, specifically relating to a device for measuring the lower limb circumference of a patient. Background Technology
[0002] When medical staff provide nursing care to patients, it is necessary to measure the circumference of the patient's lower limbs. The measurement should be taken 15 centimeters above the patella and 10 centimeters below the patella, with the patella as the center. Multiple measurements are required before the formal measurement to determine the measurement location. In order to ensure that the subsequent measurements coincide with the first measurement location, the measurement location needs to be marked after the first measurement. However, currently, staff need to mark the location with a marker after the measurement and draw circles on the patient's leg circumference, which is inconvenient for the initial measurement and marking.

[0017] Please see Figures 1-4 The present invention provides the following technical solution: a device for measuring the circumference of a patient's lower limb, including a patellar positioning plate 1, an upper extension positioning plate 2 fixedly connected to one side of the patellar positioning plate 1, a lower extension positioning plate 21 fixedly connected to the other side of the patellar positioning plate 1, a transparent positioning plate 3 fixedly connected to the other end of both the upper extension positioning plate 2 and the lower extension positioning plate 21, a measuring scale plate 31 fixedly connected to one side of the transparent positioning plate 3, a soft transparent groove plate 32 fixedly connected to the top of the transparent positioning plate 3, a marking and dyeing cotton strip 33 provided in the soft transparent groove plate 32, and a squeezing strip 34 fixedly connected to the top of the marking and dyeing cotton strip 33.
[0018] In this implementation plan: During the initial measurement of the patient's lower limb circumference, a colored liquid is applied to the lower surface of the marked and dyed cotton strip 33. The staff attaches the patellar positioning piece 1 to the patient's patella and uses the binding positioning strip 11 and Velcro 12 to bind and fix the patellar positioning piece 1 to the patient's knee. During binding, the upper extension positioning plate 2 extends to the patient's thigh, and the lower extension positioning plate 21 extends to the patient's calf, so that one measuring scale piece 31 is positioned approximately 15 cm above the patient's patella, and the other measuring scale piece 31 is positioned approximately 10 cm below the patient's patella. Subsequently, the staff wraps the measuring scale piece 31 around the outside of the patient's lower limb, adjusts the position of the measuring scale piece 31 to be appropriate, observes the scale at the overlapping point of the measuring scale piece 31, and presses the soft transparent groove plate 32 to move the marked and dyed cotton strip 33 and the compression strip 34 to adhere to the patient's skin. The liquid on the surface of the squeezing strip 34 leaves a mark on the patient's skin. When medical staff perform follow-up measurements, the soft transparent groove plate 32 is attached to the initial mark position so that subsequent follow-up measurements are taken at the same position on the patient's lower limb, making the data more consistent and comparable. The soft transparent groove plate 32 is made of transparent material so that staff can align the soft transparent groove plate 32 with the previously left mark through it. With the help of the patellar positioning plate 1, the upper extension positioning plate 2, and the lower extension positioning plate 21, the two transparent positioning plates 3 are positioned so that medical staff can easily wrap the two measuring scale plates 31 around the predetermined position on the patient's lower limb. The soft transparent groove plate 32, the marked cotton strip 33, and the squeezing strip 34 work together to mark the position of the initial measurement, so that medical staff can easily measure and mark the patient's lower limb circumference for the first time.
[0019] The patellar positioning piece 1 is fixedly connected to both sides with binding positioning strips 11, and the other end of the binding positioning strip 11 is fixedly connected with Velcro 12. The two Velcro 12s corresponding to the position can be detachably connected. By setting the binding positioning strips 11 and Velcro 12, the patellar positioning piece 1 can be bound and fixed to the patient's patella. The Velcro 12s on both sides are the female and female Velcros, so that the Velcro 12s on both sides can stick to each other to play a fixing role.
[0020] The patella positioning piece 1 has insertion grooves 13 on both sides, and a limiting groove 14 is provided on the inner wall of the insertion groove 13; by setting the insertion groove 13 and the limiting groove 14, the insertion piece 22 and the limiting block 23 can be provided with connection and movement space.
[0021] Both the upper extension positioning plate 2 and the lower extension positioning plate 21 are fixedly connected to one end of the plate, and the insert plate 22 is inserted into the insert groove 13. By setting the insert plate 22 and the limiting block 23, the patella positioning plate 1 can be connected to the upper extension positioning plate 2 and the lower extension positioning plate 21 in cooperation with the insert groove 13 and the limiting groove 14. The insert plate 22 and the limiting block 23 slide in the insert groove 13 and the limiting groove 14, so that the relative position of the upper extension positioning plate 2 and the lower extension positioning plate 21 can be adjusted, so as to facilitate the measurement of patients with bent thigh and lower leg.
[0022] A limiting block 23 is fixedly connected to the outer wall of the plug-in piece 22, and the limiting block 23 is slidably connected in the limiting groove 14. By setting the limiting block 23 and the limiting groove 14 together, the upper extension positioning plate 2 and the lower extension positioning plate 21 can be limited to prevent the upper extension positioning plate 2 and the lower extension positioning plate 21 from separating from the patella positioning piece 1. A damping pad is set between the limiting block 23 and the limiting groove 14 to facilitate the relative free sliding of the plug-in piece 22 and the patella positioning piece 1.
[0023] A pinching piece 35 is fixedly connected to one side of the transparent positioning piece 3; by setting the pinching piece 35, it is easy for the staff to pinch it, so as to avoid squeezing the soft transparent groove plate 32 and causing the marking and dyeing cotton strip 33 to be marked in the wrong position.
[0024] The working principle and usage process of this utility model are as follows: During the initial measurement of the patient's lower limb circumference, a colored liquid is applied to the lower surface of the marked and dyed cotton strip 33. The worker then attaches the patellar positioning plate 1 to the patient's patella and uses the binding positioning strip 11 and Velcro 12 to bind and fix the patellar positioning plate 1 to the patient's knee. During binding, the upper extension positioning plate 2 extends to the patient's thigh, and the lower extension positioning plate 21 extends to the patient's calf, so that one of the measuring scale plates 31 is positioned approximately 15 centimeters above the patient's patella, and the other measuring scale plate 3... Position 1 is located approximately ten centimeters below the patient's patella. Subsequently, the staff wraps the measuring scale 31 around the outside of the patient's lower limb. After adjusting the position of the measuring scale 31 appropriately, they observe the scale at the point where the measuring scale 31 overlaps. They then press the soft transparent groove plate 32 to move the marked cotton strip 33 and the squeeze strip 34 to adhere to the patient's skin. The liquid on the surface of the squeeze strip 34 leaves a mark on the patient's skin. When the medical staff conducts subsequent follow-up measurements, they attach the soft transparent groove plate 32 to the initial marked position so that subsequent follow-up measurements are taken at the same position on the patient's lower limb.
