Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a human lower limb circumference measuring device for venous thrombosis detection. Background Art

[0002] Lower extremity venous thrombosis is a common peripheral vascular disease. Venous valve insufficiency and concurrent pulmonary embolism caused by lower extremity venous thrombosis are a major risk to the patient's life safety. This disease has always been highly valued in clinical practice. Early detection and early treatment are important measures to ensure the patient's life safety. The typical clinical manifestation of lower extremity deep vein thrombosis is often swelling and pain in one lower limb (most common in the left lower limb). However, there may be no obvious symptoms in the early stage of thrombosis, which is one of the reasons why venous thrombosis is easily overlooked. The measurement of the circumference of the lower limb can timely detect the swelling of the patient's lower limb. In the current commonly used lower limb circumference measurement method in clinical practice, first determine the position of the upper and lower edges of the patella, then use a tape measure to measure 15cm of the upper edge of the patella and 10cm of the lower edge of the patella and mark them, and finally measure the circumference of the lower limb;

[0003] In the prior art, a patent with authorization publication number CN214104412U discloses a device for measuring the circumference of human lower limbs, which uses a first rectangular fabric and a second rectangular fabric as positioning parts. However, people's lower limbs are of different thicknesses, and the rectangular fabric is a flexible structure. When it is used to enclose the lower limbs, its measurement position changes, resulting in measurement errors. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model.

[0018] Please refer to Figures 1-3The present embodiment provides a technical solution: a human lower limb circumference measuring device for venous thrombosis detection, comprising an elastic Velcro strap 1, a positioning hole 3 is opened in the middle of the elastic Velcro strap 1, two groups of positioning components 4 are installed on the side of the elastic Velcro strap 1 corresponding to the position of the positioning hole 3, a connecting seat 6 is fixed to the end of the positioning component 4, a resistance component 5 is provided on the connecting seat 6, and a measuring ruler 2 is connected to the end of the resistance component 5. When the positioning component 4 is placed horizontally, the distances from the ends of the two groups of measuring rulers 2 to the left tangent position of the positioning hole 3 and the distances from the right tangent position are 15 cm and 10 cm respectively. The measuring ruler 2 is a tape measure. The elastic Velcro strap 1 is used to surround the patient's lower limbs and restrain and fix the patient's lower limbs so that the patient's patella is located in the positioning hole 3.

[0019] The positioning assembly 4 includes an ear seat 41, a rotating shaft 42 and a positioning rod 43. There are two groups of ear seats 41. The two groups of ear seats 41 are arranged at positions corresponding to the positioning holes 3 on the elastic Velcro strap 1. The end of the positioning rod 43 is rotatably connected to the ear seat 41 through the rotating shaft 42. The connecting seat 6 is fixed to the other end of the positioning rod 43. The rotating shaft 42 is a damping rotating shaft. The positioning assembly 4 also includes a level ruler 44. The level ruler 44 is installed on the back of the positioning rod 43. During measurement, the patient's legs are in a horizontal position and the measuring part is unobstructed. Then, the level of the positioning rod 43 is adjusted by the level ruler 44. The positioning rod 43 rotates relative to the ear seat 41 through the rotating shaft 42 to adjust its level. During measurement, the positioning piece remains in a horizontal state, avoiding changes in the measuring position due to differences in the thickness of a person's lower limbs when the enclosure is positioned by a rectangular fabric, thereby ensuring the accuracy of the measurement.

[0020] The interference assembly 5 includes a handle 51, a movable rod 52 and an interference block 53. The movable rod 52 is movably connected to the connecting seat 6 up and down. The handle 51 is fixed to the top of the movable rod 52, and the interference block 53 is fixed to the bottom of the movable rod 52. The end of the measuring ruler 2 is set on the interference block 53. When the positioning rod 43 is adjusted to a horizontal position, the movable rod 52 is pushed to move by the handle 51, and the movable rod 52 makes the end of the measuring ruler 2 contact the patient's leg through the interference block 53. Then, the circumference of the patient's leg is measured by the measuring ruler 2, thereby avoiding measurement errors.

[0021] The resistance block 53 is a silicone block, which is convenient for flexible contact with the patient's legs.

[0022] The working principle of a lower limb circumference measuring device for venous thrombosis detection provided by the present utility model is as follows: The elastic magic tape 1 is surrounded around the patient's lower limb to bind and fix the patient's lower limb, so that the patient's patella is located in the positioning hole 3. During measurement, the patient's leg is placed horizontally, and the measurement part is unobstructed. Then, the spirit level 44 is used to adjust the levelness of the positioning rod 43. The positioning rod 43 rotates relative to the ear seat 41 through the rotating shaft 42, so as to adjust its levelness. When the positioning rod 43 is adjusted to the horizontal position, the movable rod 52 is pushed by the handle 51 to move. The movable rod 52 makes the end of the measuring ruler 2 abut against the patient's leg through the abutting block 53. Then, the circumference of the patient's leg is measured by the measuring ruler 2.
