In-vitro simulation device for vascular intervention embolism treatment

Abstract

The invention belongs to the technical field of medical test instruments and particularly relates to an in-vitro simulation device for vascular intervention embolism treatment. The device comprises apulse pump, an organ artery module, a basic blood vessel module and a supporting structure, wherein the pulsation pump is used for supplying blood to the simulated heart pulsation; the organ artery module comprises a renal artery module, a hepatic artery module and a splenic artery module which are respectively used for simulating renal artery embolism, hepatic artery embolism and splenic artery embolism; the basic blood vessel module is used for simulating a basic blood vessel passage for the interventional catheter to enter the body; and the supporting structure is used for supporting and fixing the modules and maintaining the shape of blood vessels. The device is high in blood vessel reduction degree, can be modified according to the specific illness state, is transparent and visual, and can accurately simulate the embolism part and the embolism process.

Description

technical field [0001] The invention belongs to the technical field of medical testing instruments, and in particular relates to an in vitro simulation device for vascular interventional embolization therapy. Background technique [0002] Vascular interventional embolization has been widely used in the treatment of internal bleeding, tumor treatment, surgical resection and other fields. The technology uses a catheter to deliver an embolic agent to block blood flow in a target vessel, and the entire process is guided by real-time imaging. The key to the embolization process is whether the embolic agent is accurately and properly injected into the target blood vessel. Therefore, doctors need to slowly complete the embolism injection under X-ray fluoroscopy. This process takes up most of the operation time and will cause a lot of radiation damage to interventional doctors, which cannot be completely avoided even if they wear lead clothing. Reducing radiation damage is an urge...

Chinese utility model patent CN 207718689 U proposes an in vitro interventional embolization therapy simulation system, which simulates tiny blood vessels through a microfluidic chip, and then expresses the embolism situation. Performance testing of embolic agents

Chinese invention patent CN111816043A proposes a vascular interventional surgery simulator. Although it reproduces the shape and shape of real blood vessels relatively completely, it only contains information about major blood vessels with large diameters. , the embolism mainly occurs in the capillaries of the focal organ, so it can only simulate the process of the guide wire catheter entering the body, and it is difficult to simulate the embolization process
