Problems solved by technology

[0003] After the existing contrast agent is poured into the syringe, the suspension of the contrast agent will precipitate during the injection of the contrast agent, which makes the contrast effect unsatisfactory. Injury to the body and additional pain to the patient when the flow rate of the contrast medium is high

Embodiment approach

[0038] In order to better demonstrate the implementation process of the contrast medium injection device for cardiovascular angiographic examination in the Department of Cardiovascular Medicine, this embodiment now proposes an implementation method for the contrast medium injection device for cardiovascular angiographic examination in the Department of Cardiovascular Medicine, including the following steps:

[0039] Step 1: Input the contrast agent into the agent storage tank 141 through the agent inlet valve tube 1421, and at the same time press the air bag 1412 back and forth, and use the air input from the air bag 1412 to the agent storage tank 141 to drive the stirring blade 14111 to rotate, and the contrast agent to stir;

[0040] Step 2: After pressing the airbag 1412 for a period of time, pull the pull ring 14321 outward and simultaneously drive the liquid blocking disc 14322 to move outward, and at the same time, the contrast medium in the storage tank 141 flows into th...

Abstract

The invention discloses a contrast agent injection device for cardiovascular angiography examination in the cardiovascular medicine department and further discloses an implementation method of the contrast agent injection device for cardiovascular angiography examination in the cardiovascular medicine department. The contrast agent injection device comprises a contrast agent injection mechanism and a sleeve disc hydraulic driving mechanism, wherein the sleeve disc hydraulic driving mechanism is connected to the outer side of the bottom end of the contrast agent injection mechanism in a sleeving mode. According to the contrast agent injection device, before a contrast agent in an agent storage tank is input into an inner tube, a pressing air bag can be pressed in a reciprocating mode, air is input into the agent storage tank through the pressing air bag, air turbulence is caused, a rotating shaft is driven to rotate by utilizing the air flow generated by the air turbulence, the contrast agent is continuously stirred through stirring blades connected to the upper end of the rotating shaft, so that the contrast agent is prevented from precipitating and forming small blocks; and meanwhile, the contrast agent is transferred into the inner tube, so that the contrast agent can be conveniently injected subsequently, and meanwhile, the amount of the contrast agent entering the inner tube can be conveniently controlled through the length of a liquid blocking circular plate which is pulled out.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a contrast agent injecting device for cardiovascular angiographic examination in the department of cardiovascular medicine and an implementation method thereof. Background technique [0002] Contrast agents are chemicals that are injected or administered into human tissues or organs to enhance image viewing. These articles are denser or lower than the surrounding tissue, creating a contrast that displays images with certain devices. Because many tissue structures of the human body are not visible on X-ray films, they can only be displayed in depth by using contrast agents. Some X-ray examination techniques, such as angiography, cannot be performed without contrast agents. Although a contrast medium is not always necessary for some techniques, its use will help the doctor to make a more reliable diagnosis for you by making the diagnostic image clearer. At present, the mo...
