7 results about "Lower extremity veins" patented technology

This invention discloses a non-invasive real-time monitoring and intervention system for preventing and treating lower extremity deep vein thrombosis (DVT). It is characterized by comprising an impedance monitoring module, a microcurrent stimulation module, and a data analysis and display module. The impedance monitoring module is connected to the data analysis and display module and includes an impedance measurement circuit and a ring-shaped flexible electrode patch. The ring-shaped flexible electrode patch employs a ring-shaped multi-electrode array composed of multiple sets of electrodes, with current injected into the distal electrodes and voltage difference detected at the proximal electrodes. The impedance monitoring module measures changes in lower extremity impedance through the ring-shaped multi-electrode array. The microcurrent stimulation module is connected to the data analysis and display module and uses a constant current source output. The data analysis and display module includes a main controller and a display. The main controller combines a machine learning model to predict DVT risk, achieving closed-loop control. This invention exhibits good stability, achieving non-invasive, real-time, continuous monitoring and active intervention, overcoming the shortcomings of existing monitoring and prevention technologies.

The utility model relates to medical measuring instrument technical field, and disclose a kind of lower limb venous thrombosis leg circumference measuring scale, including frame, the both ends of frame are fixedly connected with magic band, the inside fixed connection of frame has two long poles, the surface sliding connection of long pole has three sliding plates, two The inside fixed connection of sliding plate has slide bar, the surface sliding connection of slide bar has sliding block, the surface sliding connection of sliding plate has casing.This lower limb venous thrombosis leg circumference measuring scale, by setting the sliding rule to the both ends of patella center point, so that the patella center line is obtained after marking pen, two sliding rules can be respectively aligned with the upper and lower measurement area position of patella, guarantee the accuracy of the measurement position of sliding rule compared with the midpoint line of patella, more conducive to the measurement of patient venous thrombosis leg circumference in clinical application.

The application relates to a traditional Chinese medicine composition for treating varicose veins of lower limbs and application thereof, and belongs to the technical field of traditional Chinese medicines. The application provides a traditional Chinese medicine composition for treating varicose veins of lower limbs, which is composed of 30-60 parts of radix paeoniae alba, 6-40 parts of prepared licorice, 3-12 parts of prepared aconite, 15-30 parts of chuanxiong rhizome and 20-30 parts of eucommia ulmoides, and has the effects of strengthening suction, promoting reflux, balancing suction and pushing, activating blood and resolving stasis, fixing pulse and repairing, relaxing varicose veins and preventing thrombus, so that the application can treat both symptoms and root causes and can be prepared into a pharmaceutically acceptable oral dosage form.

This utility model relates to a tool for measuring leg circumference, belonging to the field of medical auxiliary device technology. It includes a flexible measuring tape, and further includes a primary positioning ruler and a secondary positioning ruler that are slidably connected. The bottom of the secondary positioning ruler has a fixed piece and a movable piece slidably connected thereto. A flexible measuring tape is located on one side of the primary positioning ruler, and one end of the flexible tape is slidably connected to the primary positioning ruler. The secondary positioning ruler has an I-shaped structure, and a vertical through-type groove that cooperates with the secondary positioning ruler is opened at the center of the primary positioning ruler. The tool for measuring leg circumference provided by this utility model, through the cooperation of the primary positioning ruler, secondary positioning ruler, fixed piece, movable piece, and flexible measuring tape, can quickly and accurately locate the position 15cm above and 10cm below the midpoint of the patella for leg circumference measurement, comprehensively improving the convenience of leg circumference measurement when monitoring the treatment effect of lower extremity deep vein thrombosis.

This application relates to the technical field of medical devices, and in particular to a multimodal collaborative lower limb ankle pump motion assistive device, which includes a main controller, a foot drive module composed of bilinear push rods and universal ball joints, a calf gradient pressurization module with a multi-chamber airbag, and a carbon fiber support structure. This application achieves precise timing coordination of mechanical drive and pneumatic pressurization through the main controller. During plantar flexion, sequential pressurization is applied to the calf muscle group from distal to proximal, and pressure is simultaneously released during dorsiflexion, thus highly simulating the physiological muscle pump effect. The device supports multiple movement modes such as dorsiflexion, plantar flexion, and compound circumduction, and integrates pressure, angle, and hemodynamic monitoring units to achieve closed-loop feedback control and risk warning. This application can significantly improve the efficiency of lower limb venous blood return, effectively prevent deep vein thrombosis, reduce the workload of medical staff, and is suitable for various scenarios such as ICU critical care, postoperative rehabilitation, and long-distance travel.
