This application discloses a method and system for microvascular anastomosis modeling and effect prediction in assisted spermatic cord anastomosis, relating to the field of data processing technology. The method includes: extracting the pampiniform plexus topology and varicose vein segments from a three-dimensional vascular tree model of the spermatic veins constructed based on spermatic cord vessel images; determining candidate diversion inlet locations based on the spatial adjacency relationship between the obstructed reflux nodes identified by the varicose vein segments and the pampiniform plexus topology; spatially registering the contour of the inferior epigastric vein segmented from the superficial vein images of the inguinal region with the candidate diversion inlet locations to generate a diversion anastomosis path planning map; constructing the geometric configuration of the end-to-side anastomosis and performing hemodynamic simulation to generate a wall shear stress distribution field, assess the thrombosis tendency of the end-to-side anastomosis, and generate a postoperative patency rate prediction value. This application can predict the risk of thrombosis preoperatively through hemodynamic simulation, providing a reliable basis for surgical planning and effectively improving the success rate of the surgery.

The present invention relates to an orthosis for compressing superficial veins (SV) in the lumbar spine region. More specifically, the purpose of the present invention is to alleviate lower back pain or immediately improve the symptoms thereof by gently and evenly pressing SVs in the skin of the lumbar spine region, in order to treat or alleviate lower back pain due to an insufficiency of SVs distributed over the lumbar spine connection. A rectangular orthosis main body (100), which is made of memory foam having a hardness of 1 to 5 or an inflatable member, has a shape corresponding to the musculoskeletal shape of the lumbar spine region, and gently and evenly presses the skin over the SVs, includes a lumbar vertebrae region (10), a lumbar spine connection (20), and a sacral region (30), which are integrally formed.

This invention provides a control method, apparatus, and computer-readable storage medium for a blood purification device. The method includes: responding to a connection between an extracorporeal circulation tubing connected to the blood purification device and a user's peripheral superficial vein, acquiring a first diameter of the peripheral superficial vein when the flow velocity of the blood driving unit in the blood purification device is zero; increasing the flow velocity of the blood driving unit every first preset time interval and acquiring a first real-time flow velocity of the extracorporeal circulation tubing until the diameter deviation between a second diameter of the peripheral superficial vein at the first real-time flow velocity and the first diameter does not meet a first safety condition; determining a target flow velocity based on multiple acquired first real-time flow velocities, wherein the diameter deviation between the diameter of the peripheral superficial vein at the target flow velocity and the first diameter meets the first safety condition; and controlling the blood driving unit to operate at the target flow velocity. The technical solution of this invention improves the safety of blood purification for users.
