Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional and convenient leg circumference measuring tool. Background Technology
[0002] For patients with deep vein thrombosis in the lower extremities, measuring leg circumference is a common clinical method to observe the degree of swelling in the affected limb. The traditional method involves measuring the thigh circumference approximately 15cm above the patella and the calf circumference 10cm below the patella using a tape measure. However, this method has several drawbacks in clinical practice:
[0003] 1. The measurement process requires holding the tape measure by hand, which requires both hands to operate, making it inconvenient to read the measurement and record the values. This can easily lead to errors in the measurement results and may even result in incorrect readings, which in turn can affect subsequent clinical judgment.
[0004] 2. During the measurement process, nursing staff need to draw lines on the patient's patella and upper and lower legs for positioning. The irremovable marking lines seriously affect the patient's physical appearance and reduce the patient's medical experience.
[0005] 3. During the measurement process, nursing staff need to position the body, expose the lower limbs, locate and mark the knees and upper and lower legs separately, and measure the circumference of the upper and lower legs separately with a soft measuring tape. The above operation steps are cumbersome and time-consuming, which increases the workload of medical staff.
[0006] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0007] The purpose of this invention is to provide a multifunctional and convenient leg circumference measuring tool. This multifunctional and convenient leg circumference measuring tool improves the positioning effect and clinical work efficiency by utilizing its own structure, and improves the measurement accuracy by utilizing the magnetic attraction principle.
[0008] This utility model provides a multifunctional and convenient leg circumference measuring tool, including a central positioning plate, a silicone positioning anti-slip plate, an upper leg circumference connecting strap, a lower leg circumference connecting strap, an upper leg circumference measuring tape, and a lower leg circumference measuring tape. The central positioning plate is circular, and the silicone positioning anti-slip plate is connected to the bottom of the central positioning plate. The silicone positioning anti-slip plate is annular. The upper leg circumference connecting strap and the lower leg circumference connecting strap are detachably connected to the upper and lower ends of the central positioning plate, respectively. The upper leg circumference measuring tape is rotatably connected to the other end of the upper leg circumference connecting strap, and the lower leg circumference measuring tape is rotatably connected to the other end of the lower leg circumference connecting strap.
[0009] Using the above technical solution, the silicone positioning anti-slip pad is placed on the patient's patella during use. The thigh circumference is measured by wrapping the upper leg circumference measuring tape around the patient's thigh, and the lower leg circumference is measured by wrapping the lower leg circumference measuring tape around the patient's calf. The design of the upper and lower leg circumference connecting straps being detachably connected to the central positioning pad allows the lower leg circumference connecting strap and lower leg circumference measuring tape to be removed as needed, and the upper leg circumference connecting strap and upper leg circumference measuring tape to be used alone. This is suitable for patients who have undergone lower leg amputation or lower limb surgical bandaging, where it is inconvenient to measure the lower leg circumference. The silicone positioning anti-slip pad adheres tightly to the patient's skin, preventing the leg circumference measuring instrument from moving during the measurement process, improving the positioning effect, and further improving the measurement accuracy.
[0010] Furthermore, the multifunctional portable leg circumference measuring tool also includes a connecting buckle, which includes a male buckle and a female buckle. The male buckle is connected to both the upper and lower ends of the central positioning piece, and the female buckle is connected to the ends of the upper leg circumference connecting strip and the lower leg circumference connecting strip. The female buckle is pressed onto the male buckle.
[0011] Furthermore, the multifunctional portable leg circumference measuring tool also includes a soft iron sheet and a magnetic head. The soft iron sheet is elongated. The soft iron sheet is connected to both the upper leg circumference measuring tape and the lower leg circumference measuring tape, and the magnetic head is connected to the other end of both the upper leg circumference measuring tape and the lower leg circumference measuring tape.
[0012] Furthermore, scale lines are provided on the upper leg connecting strip and the lower leg connecting strip.
[0013] Furthermore, the width of the upper leg connecting band is greater than the width of the lower leg connecting band.
[0014] Furthermore, both the upper leg band and the lower leg band have an anti-slip coating on their undersides.
[0015] Furthermore, the width of the upper leg circumference measuring tape is greater than the width of the lower leg circumference measuring tape.
[0016] Furthermore, the multi-functional portable leg circumference measuring tool is available in three sizes: large, medium, and small.
[0017] This utility model discloses a multifunctional and convenient leg circumference measuring tool. During use, a silicone positioning anti-slip plate is placed on the patient's patella. Using the positioning marks of the upper and lower leg circumference connecting straps, the upper leg circumference measuring tape is wrapped around the patient's thigh to measure thigh circumference, and the lower leg circumference measuring tape is wrapped around the patient's calf to measure calf circumference. The design of the upper and lower leg circumference connecting straps being detachably connected to the central positioning plate allows for the removal of the lower leg circumference connecting strap and the lower leg circumference measuring tape as needed, enabling the use of the upper leg circumference connecting strap and the upper leg circumference measuring tape alone. This is particularly useful for patients with lower leg amputations or those whose lower limbs are bandaged during surgery, making lower leg circumference measurement inconvenient. The silicone positioning anti-slip plate prevents the leg circumference measuring instrument from moving during measurement, improving positioning effectiveness and further enhancing measurement accuracy. This utility model features a simple structure, convenient operation, and the ability to simultaneously measure thigh and calf circumferences. It offers integrated and efficient measurement, allowing for multiple repeated measurements to improve accuracy, and boasts high repeatability. It addresses patients' aesthetic concerns and increases patient satisfaction. Attached Figure Description
