Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a portable rapid leg circumference measurement device. Background Technology

[0002] Leg circumference measurement is suitable for assessing deep vein thrombosis in the lower extremities, orthopedic trauma and postoperative swelling of the lower extremities, and preoperative and postoperative swelling assessment of lower extremity vascular diseases. It is usually measured at a fixed position above and below the knee. To facilitate the measurement, a rapid leg circumference measurement device is needed.

[0003] However, existing rapid leg circumference measurement devices have the following drawbacks:

[0004] (1) Existing leg circumference rapid measurement devices have weak portability. Traditional leg circumference rapid measurement devices occupy a lot of space and are inconvenient to carry, resulting in limitations and difficulties in portability.

[0005] (2) Existing leg circumference rapid measurement devices have a weak function in improving measurement accuracy. Traditional leg circumference rapid measurement devices require manual holding of one end of the measuring ruler for measurement, which is a troublesome process. The measuring ruler is also prone to tilting after it is in contact with the leg, which can easily lead to inaccurate measurement values. Utility Model Content

[0006] The purpose of this invention is to provide a portable, rapid leg circumference measuring device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable leg circumference rapid measuring device, comprising a box body, a fixing block fixedly connected to the outer surface of the box body, a hinge shaft provided on the inner side wall of the fixing block, an arc-shaped rod hinged to the outer surface of the hinge shaft, an extension block fixedly connected to one end of the arc-shaped rod, a rectangular locking block fixedly connected to the side of the extension block, a connecting plate provided on the outer surface of the rectangular locking block, a measuring ruler provided inside the box body, a limit slider fixedly connected to one end of the measuring ruler, a connecting block fixedly connected to the side of the box body away from the connecting plate, and a limit groove formed on one side of the connecting block.

[0008] Optionally, the inner sidewall of the connecting plate is provided with a rectangular slot, and the rectangular block fits into the rectangular slot. When the rectangular block is inserted into the rectangular slot, the rectangular slot limits the rectangular block, so that the position of the rectangular block is stabilized inside the rectangular slot, thereby stabilizing the position of the arc rod and connecting the arc rod with the connecting plate.

[0009] Optionally, a connecting groove is provided on one side of the surface of the box body, and the connecting plate is connected to the connecting groove. The connecting groove connects and fixes the connecting plate to the box body, so that the position of the connecting plate is fixed at this time.

[0010] Optionally, a fixing groove is provided on the outer surface of the box body, and an anti-slip pad is fixedly connected inside the fixing groove. The fixing groove connects the anti-slip pad to the box body. The anti-slip pad has anti-slip properties, and the connection with the box body can reduce the possibility of the device slipping from the hand when holding the device.

[0011] Optionally, a rectangular groove is provided on the side of the box body near the connecting block. A protective pad is fixedly connected inside the rectangular groove. The rectangular groove connects the protective pad to the box body. The protective pad is made of a relatively soft material, which can reduce friction when the patient's leg is in contact with the box body.

[0012] Optionally, the measuring ruler has a total length of one meter and is made of a combination of silicone and nylon. The combination of silicone and nylon is soft and durable, has good elasticity and resilience, and is easy to clean and disinfect. It is suitable for one person to use and disinfect once, reducing the risk of cross-infection.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This portable leg circumference rapid measurement device, through the arrangement of a fixed block, hinge shaft, arc rod, extension block, rectangular locking block, and connecting plate, allows for easy operation. When the arc rod is rotated, the hinge shaft limits its movement, while the fixed block supports it. When the arc rod reaches a certain position, the extension block enters the connecting plate, at which point the rectangular locking block engages with a slot within the connecting plate, fixing the arc rod in place and sealing both sides. This facilitates handheld and hanging of the device. The device is compact and convenient, achieving portability and avoiding the limitations of traditional leg circumference rapid measurement devices that occupy significant space and are inconvenient to carry.

[0015] 2. This portable leg circumference rapid measurement device, through the setting of a measuring ruler, a limiting slider, a connecting block, and a limiting groove, allows for easy use. When the measuring ruler is pulled around the leg once, the limiting slider is slid into the limiting groove. Simultaneously, the limiting groove limits the limiting slider. When the limiting slider and the limiting groove are fully engaged, the measuring ruler is released, allowing for a direct observation of the measurement value and a quick understanding of one's leg circumference. Furthermore, the measuring ruler will not loosen or slip during measurement, thus improving measurement accuracy. This avoids the inconvenience of traditional leg circumference rapid measurement devices, which require manual holding of one end of the measuring ruler, and the tendency for the measuring ruler to tilt after being engaged with the leg, leading to inaccurate measurements.
