Embodiment Construction

[0022] The technical solution of the present invention will be further introduced below in conjunction with specific implementation methods and accompanying drawings.

[0023] This specific embodiment discloses a simulation experiment device based on DSA subtraction technology, which includes a support body, thin tubes for simulating human blood vessels and auxiliary pushing equipment.

[0024] The support body is a cube of 30cm*30cm*30cm, the material is plexiglass, and the inside is hollow. There is a round opening with a cover on the top of the support body. There is a hole on each of the two opposite corners of the support body. The hole can be For thin tubes to pass through, the support body is used to simulate different fat and thin human bodies by injecting different amounts of water.

[0025] Thin tubes are used to simulate human blood vessels. They are relatively soft in texture and must have clinical effects similar to blood vessels in DSA subtraction technology. Sp...

Abstract

The invention discloses a simulation experiment device based on a DSA subtraction technique. The device comprises a supporting body, a fine tube for simulating the human body blood vessel, and auxiliary pushing equipment. The supporting body is used for simulating human bodies of different weights by injecting water of different quantities, the fine tube penetrates through the supporting body, and the auxiliary pushing equipment is used for injecting water or a medical contrast agent into the fine tube. The invention further discloses a simulation experiment method based on the DSA subtraction technique. The clinical effect of DSA subtraction can be effectively simulated, and the simulation experiment device and method are low in cost, safe and easy to use.

Description

technical field [0001] The invention relates to a simulation experiment device and method, in particular to a simulation experiment device and method based on DSA subtraction technology. Background technique [0002] Digital subtraction angiography (DSA) is a digital imaging subtraction technique combined with X-ray angiography and modern computer technology applied in clinical medicine after CT, which has great advantages in diagnosing diseases and interventional radiology and great clinical value. In the actual development and application, it is necessary to simulate the real angiography process through the experimental device to verify the effectiveness of the development. However, there is no device in the prior art that can effectively simulate a real angiographic procedure. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a simulation experiment device and method based on DSA subtraction technology capa...
