Description

Portable thrombus risk assessment ruler

Technical Field

The utility model relates to the field of medical technology, concretely relates to portable thrombus risk assessment chi.

Background

Deep vein thrombosis refers to abnormal coagulation of blood in deep veins, and belongs to the disease of venous reflux disorder of lower limbs. After thrombosis, most of the thrombus can spread to the deep trunk of the vein of the whole limb except for a few parts which can be ablated or limited to the occurrence positions, and most of the thrombus can evolve into thrombosis sequelae if the thrombus cannot be diagnosed and treated in time.

Clinically, the risk assessment of deep vein thrombosis often requires the measurement and recording of corresponding data. The circumference of the lower limb venous thrombus is measured by using measuring scales, which generally comprise an upper measuring scale, a lower measuring scale and a telescopic scale. When measuring, the upper measuring ruler is used for measuring the periphery of the thigh, the lower measuring ruler is used for measuring the periphery of the shank, and then the distance between the thigh and the shank is read through the telescopic ruler. In addition, during measurement, attention needs to be paid to fully exposing a measured part, the measured part is consistent with a placed body position, measurement needs to be objective, and result errors caused by interference of subjective factors are avoided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The portable thrombus risk assessment ruler shown in fig. 1-3 comprises a graduated scale 1, wherein a limiting clamp 2 is arranged in the middle of the graduated scale 1, the limiting clamp 2 is correspondingly hinged to two sides of the graduated scale 1, a return spring 21 is arranged at the hinged joint of the limiting clamp 2 and the graduated scale 1, sliding seats 3 are arranged on two sides of the graduated scale 1, the sliding seats 3 are slidably sleeved on the graduated scale 1, a limiting groove 11 is formed in the connecting side wall of the graduated scale 1 and the sliding seats 3, a plurality of clamping grooves 12 are formed in the limiting groove 11, an elastic clamp 31 is fixedly arranged at the joint of the sliding seats 3 and the graduated scale 1, the elastic clamp 31 extends into the limiting groove 11, the elastic clamp 31 is clamped with the clamping grooves 12, a rubber tape 4 is arranged on the sliding seats 3, the rubber tape 4 is wound on a rotating shaft 41, and the rotating shaft 41 is fixed on the sliding seats 3 through a bearing seat 42.

The first embodiment:

preferably, scale markings 13 are provided on the outside of the scale 1.

Furthermore, an indicator 32 is fixed on the slide base 3, and the indicator 32 is correspondingly matched with the scale mark 13.
