Multifunctional auxiliary device for angiography in cardiovascular medicine department

Abstract

According to a multifunctional auxiliary device for angiography in the cardiovascular medicine department, disclosed by the present invention, firstly, the electric equivalent injection can be achieved by means of an electric push rod, it is guaranteed that a contrast agent is stably and safely injected into the body of a patient, and meanwhile, infrared detection is conducted on the contrast agent by means of an infrared induction light curtain, and therefore medical staff can conveniently master the injection capacity of the contrast agent, and the ensuring accuracy of interventional radiography is guaranteed; secondly, the contrast agent can be placed in a weight detection groove, the contrast agent above can be weighed and detected by means of a weight sensor, medical staff can know the total volume of the contrast agent before intervention, and meanwhile, the contrast agent can be heated by means of a heater to enable the contrast agent to be close to the body temperature of a human body, so that the temperature difference stimulation caused by subsequent injection of the contrast agent into a blood vessel is reduced, and the protection to the patient is improved; finally, air can be injected into a radiography compression belt assembly by operating an electronic air pump, compression hemostasis of the femoral artery puncture position is achieved, and the purpose of convenient nursing of the postoperative patient is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional auxiliary device for angiography in cardiovascular medicine. Background technique [0002] Cardiovascular angiography is to quickly inject contrast agent into the heart cavity or blood vessel through the interventional catheter, so that the heart and blood vessel cavity can be visualized under X-ray irradiation. The development process is photographed, and the blood flow sequence containing the contrast agent and the filling of the heart vessels can be seen from the results of the development, so as to understand the physiological and anatomical changes of the heart and blood vessels. It is a valuable method for diagnosing cardiovascular diseases. Usually, selective right heart angiography, left heart angiography, pulmonary angiography, aortic angiography, coronary angiography and hepatic artery, renal artery, cerebrovascular, celiac artery, Mesenteric ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the high viscosity of the contrast medium, the bolus injection is difficult, so it is not only time-consuming and laborious, but also greatly affects the stability of the bolus injection. At the same time, the medical staff cannot accurately grasp the injection amount of the contrast medium, which affects the Operational Safety and Accuracy

[0005] 2. There is a gap between the temperature of the contrast agent and the body temperature of the patient. When the temperature contrast agent enters the blood vessels of the human body, there will be greater stimulation, which will bring great discomfort to the patient and affect the blood vessels.

[0006] 3. After the intervention, the patient’s femoral artery puncture site lacks adjustable pressure, so it is inconvenient to stop the bleeding, which affects the clinical nursing operation, and there is a risk of bleeding infection
