Clinical contrast injection device for cardiovascular medicine and injection method

Abstract

The invention discloses a clinical radiography injection device and method for the cardiovascular medicine department and particularly relates to the technical field of medical instruments, the clinical radiography injection device comprises a first connecting cylinder and a second connecting cylinder, a needle seat is arranged on the front face of the second connecting cylinder, and a pillow is arranged on the front face of the needle seat; the inner wall of the first connecting cylinder is in lap joint with the outer surface of the piston push plate. By arranging a threaded piston rod, a control plate, a first gear, a second gear, a lead screw, a filter plate and a heating stirring rod, a threaded cylinder drives the lead screw and the filter plate to move forwards, and after the filter plate makes contact with a needle base, a piston push plate directly extrudes a contrast agent to penetrate through the filter plate to enter a human body; the filter plate can filter rubber particles possibly existing in the contrast agent, the situation that the rubber particles enter the human body is avoided, meanwhile, the heating stirring rod stirs, disperses and heats the contrast agent before injection of the contrast agent, smooth injection of the contrast agent is guaranteed, and meanwhile the comfort of the contrast agent entering the human body during injection is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical appliances, more specifically, the invention relates to a clinical contrast injection device and injection method for cardiovascular medicine. Background technique [0002] Contrast agent, as the name suggests, also known as contrast agent, is a chemical product that is injected or taken into human tissues and organs to enhance the effect of image observation. The density of these products is generally higher or lower than that of the surrounding tissue, and the resulting contrast is displayed with certain devices, such as iodine preparations and barium sulfate commonly used in X-ray observation, which are specially provided for the development of lesions. [0003] Contrast agents can increase the difference between normal and abnormal tissues, so they can assist doctors in detecting abnormal morphology and functional damage of human organs. And enable doctors to discover and identify some early,...

Problems solved by technology

[0007] The contrast agent is mostly stored in the contrast agent container. When the injection device extracts the contrast agent from the contrast agent container, since the contrast agent container is sealed with a rubber cover, rubber particles may fall off when the needle of the injection device punctures the rubber cover. As the contrast agent enters the injection device, rubber particles may enter the patient's body and cause harm to the human body. At the same time, the viscosity of the contrast agent may increase due to the low temperature inside the injection device, which may affect the smooth injection of the contrast agent. Therefore, a psychological Clinical contrast injection device and injection method used in Department of Vascular Medicine to solve the above problems
