Description

technical field [0001] The invention relates to the field of cardiovascular medicine, in particular to a cardiovascular imaging device. Background technique [0002] In the basic operation of the current angiography operation, the catheter is inserted into the patient's blood vessels and corresponding body chambers, and then the contrast agent is injected into the angiography work. The current device used is a syringe, but the viscosity of the contrast agent is extremely high. It is very laborious to inject the push-type syringe. In addition, during the imaging process, the injection work needs to be carried out slowly, otherwise it will cause danger. During the injection, the contrast agent sticks together and cannot be spread out quickly when it enters the corresponding chamber. The time for follow-up inspection is increased, and the current push-and-push injection method has relatively large defects. In addition, when the weather is relatively cold, the degree of adhesio...

Problems solved by technology

[0002] In the basic operation of the current radiography operation, the catheter is inserted into the patient's blood vessels and corresponding body chambers, and then the contrast agent is injected into the radiography work. The device currently used is a syringe, but the viscosity of the contrast agent is extremely high. It is very laborious to inject the push-type syringe. In addition, during the imaging process, the injection work needs to be carried out slowly, otherwise it will cause danger. During the injection, the contrast agent sticks together and cannot be spread out quickly when it enters the corresponding chamber. The time for follow-up inspection is increased, and the current push-and-push injection method has major defects

In addition, when the weather is relatively cold, the degree of adhesion of the contrast agent is increased, and it is more difficult to inject such as in the patient's body.

[0003] Most of the angiography methods currently on the market are manual syringe angiography. Because it is manual injection, because each person's strength is different, the injection flow rate is also different during the injection process. Due to the high density of the contrast agent itself , is a viscous liquid, the injection flow rate is relatively slow, and the entire injection time is also long, and at the same time, the flow rate cannot be maintained at a uniform and stable level; and most of the traditional devices of this type do not have the function of contrast agent heating. It is easy to make patients feel uncomfortable, increase tension, bring inconvenience to the work of medical staff, and is not conducive to internal cleaning after use
