Description

Patella positioning leg circumference measuring device

Technical Field

The utility model relates to an auxiliary instrument for medical treatment, in particular to a measuring device for leg circumference measurement.

Background

Venous Thromboembolism (VTE) refers to the condition of plaque formation in the blood of veins, most commonly in the deep veins of the lower extremities, known as deep vein thrombosis. Emboli may fall out of the site where they were generated and enter the blood circulation, a condition known as embolism. VTE has a wide variety of clinical manifestations. Venous thrombosis is generally asymptomatic, with occasional pain and edema of the lower extremities. Some emboli can enter the lungs, resulting in potentially fatal pulmonary embolism. Symptomatic venous thrombosis often results in a series of complications. Chronic venous insufficiency can lead to long-term symptoms. Thus resulting in venous ulcers and alterations of the limb after embolic events, manifested as chronic pain, swelling and skin changes.

Clinically, for such patients, nurses need to measure leg circumferences of the swollen lower limbs every day, judge whether the patient's condition is improved or worsened through the change of the leg circumferences, and take different nursing measures. The nurse commonly uses a tape measure to measure the leg circumference of the patient, and uses the tape measure to measure the thigh circumference with the midpoint of the patella upwards of about 15cm and the shank circumference with the midpoint of the patella downwards of about 10 cm; when the measuring tape is used for measuring, a nurse needs to hold the measuring tape with two hands for operation, the measured leg circumference data and the readings have larger errors, and simultaneously, the recording of the measured data on the opposite sides is inconvenient; in addition, when the leg circumference is measured, the measurement cannot be ensured to be carried out at the same position every time, and the position deviation is caused, so that the measured data is meaningless. The limb circumference measuring instrument capable of being accurately positioned is designed to ensure that each measurement is at the same position, such as Chinese patent publication No. CN214511155U, and the name of the limb circumference measuring instrument is limb circumference measuring instrument, and the limb circumference measuring instrument can ensure that each measurement is at the same position, but has complex structure, heavy weight and complex operation, and is very inconvenient for nurses to measure patients in different rooms back and forth.

Therefore, there is a need for a patella positioning leg circumference measuring device that is simple in structure, convenient to operate and portable.
