Description

Technical Field

[0001] The utility model belongs to the technical field of medical care, and in particular relates to a leg circumference measuring device for VTE patients. Background Art

[0002] Venous thromboembolism (VTE) refers to the formation of blood plaques in veins, most commonly in the deep veins of the lower extremities, known as deep vein thrombosis. Clinically, for such patients, nurses need to measure the leg circumference of their swollen lower extremities every day, and judge whether the patient's condition is improving or worsening by the changes in leg circumference, and then take different nursing measures based on this.

[0003] The conventional measuring tool for measuring the leg circumference of VTE patients is a tape measure. During operation, the thigh circumference is measured at about 15 cm above the upper edge of the patella, and the calf circumference is measured at about 10 cm below the lower edge of the patella. Therefore, medical staff need to measure the 15 cm above the upper edge of the patella and the 10 cm below the lower edge of the patella and mark them every time they measure the leg circumference of the patient. The operation steps are cumbersome and inconvenient for medical staff to operate. To this end, we propose a VTE patient leg circumference measuring device. Utility Model Content

[0013] The utility model of a VTE patient leg circumference measuring device has the following advantages:

[0014] 1. A VTE patient leg circumference measuring device, by setting a sole fixer and a distance measuring component, needs to mark the 15cm position of the upper edge of the patella and the 10cm position of the lower edge of the patella on the patient's leg when used for the first time, then use a strap to fix the sole fixer to the sole of the patient's foot, and then use a first tape measure to measure the distance from the slider to the marked 10cm position of the lower edge of the patella and the distance from the slider to the marked 15cm position of the upper edge of the patella, and record the sizes. Compared with the prior art, the device is better in measuring the distance of the slider with the first tape measure. After measuring the distance from the block to the marked 10cm position of the lower edge of the patella and the distance from the slider to the marked 15cm position of the upper edge of the patella, and recording them, the medical staff can directly use the sole of the patient as the reference when measuring next time, and then pull the first tape measure to initially record the distance from the slider to the marked 10cm position of the lower edge of the patella and the distance from the slider to the marked 15cm position of the upper edge of the patella, so as to quickly determine the measurement position, which changes the defect of cumbersome operation steps of using traditional tape measures and facilitates the use of medical staff.

[0015] 2. A VTE patient leg circumference measuring device is provided with a circumferential measuring component. Pulling the second tape measure can drive the second winding roller and the driving shaft to rotate forward, and the driving shaft can drive the clockwork spring to contract. When the second tape measure is wrapped around the patient's leg, the insert block can be inserted into the slot, so that the insert block can be limited. After that, the clockwork spring can use the reset force to drive the driving shaft and the second winding roller to reverse and rewind the second tape measure. The second tape measure is rewound by the reset force of the clockwork spring, so that the second tape measure has a certain tightening force to adhere to the patient's skin, avoiding the error of different medical staff tightening the second tape measure excessively during manual measurement, causing excessive concavity of the skin and affecting the measurement.
