Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a contrast agent injection device.
Background
Contrast agents are chemicals that are injected or administered into human tissues or organs in order to enhance the visual effect. These articles are denser or less dense than the surrounding tissue and the contrast produced is imaged with some instruments. Since many tissue structures of the human body are not visualized on an X-ray film, they can only be "darkened" by using contrast agents, some X-ray examination techniques, such as angiography, will not be performed away from the contrast agents. In some techniques (e.g., CT), although contrast agents are not always necessary, the use of contrast agents can make diagnostic images more sharp, thereby helping physicians make more reliable diagnoses for you.
When a patient has a cardiovascular disease, the position and condition of the disease need to be determined, and the current common method for determining the position and condition of the disease is to infuse a contrast medium into the cardiovascular vessel and then determine the position and condition of the cardiovascular vessel through CT contrast scanning. At present, the most commonly used method for infusing contrast medium is to extract contrast medium by a contrast medium syringe, directly or indirectly connect with a contrast catheter and inject the contrast medium, so that the contrast medium is injected into the cardiovascular, and contrast the cardiovascular to determine the lesion position or the lesion condition. However, after the contrast agent is uniformly stirred and poured into the injector, the contrast agent needs suspension liquid to precipitate in the process of interventional injection of the contrast agent, so that the contrast effect is not ideal. If the contrast agent is injected into the human body after being agglomerated, the body may be damaged.
Because the high-pressure injection of the contrast agent has high pressure and high speed, and the blood vessel factors of a patient easily cause the contrast agent to leak out of the blood vessel, if the contrast agent is not timely treated or is not properly treated, a patient has local swelling, pain and blood stasis; the serious patient causes necrosis of the surrounding subcutaneous tissue and even dysfunction, which causes pain to the patient, so that the flow of the contrast agent needs to be controlled.
