Embodiment Construction

[0045] see Figure 1 to Figure 5 Shown:

[0046] The device for cadaver-targeted cardiovascular and cerebrovascular imaging provided by the present invention includes a main pipe 1, a connector 2 and an extension tube 3, wherein the main pipe 1 is connected to the extension pipe 3 through the connector 2, and the main pipe 1 is provided with gas passages and Contrast agent channel, the main tube 1 is also covered with a balloon 4, the gas outlet of the gas channel in the main tube 1 is connected with the air bag 4, the contrast medium channel in the main tube 1 is connected with the extension tube 3 through the connector 2, and the contrast agent is passed through the extension tube 4. The tube 3 can be injected into the contrast agent channel in the main pipe 1, and the connecting head 2 is also connected with a gas delivery tube 5, which communicates with the gas channel in the main tube 1 through the connecting head 2, and the gas enters the gas channel through the gas deli...

Abstract

The invention discloses a corpse targeted heart and cerebral vessel radiography device and method.The radiography device comprises a main pipe, a connector and a lengthened pipe, the main pipe is connected with the lengthened pipe through the connector, a gas channel and a contrast agent channel are arranged in the main pipe side by side, and the main pipe is further sleeved with an air bag; and an air outlet of the air channel in the main pipe is communicated with the air bag. The radiography method comprises the following steps: step 1, scanning a corpse; 2, exposing and dissociating the femoral artery; step 3, feeding the guide wire into the femoral artery; 4, leaving the guide wire in the blood vessel; step 5, emptying air; step 6, slowly inserting the tip into the femoral artery; seventhly, the air bag is inflated to the fixed position; 8, repeating the step 7; step 9, emptying the air; step 10, cardiac targeted angiography is carried out; and step 11, performing evaluation. The method has the beneficial effects of preventing the contrast agent from regurgitating, reducing the dosage of the contrast agent, and being low in price and easy to operate.

Description

technical field [0001] The present invention relates to a cardio-cerebrovascular angiography device and method, in particular to a cadaver-targeted cardio-cerebral angiography device and method. Background technique [0002] At present, many relevant institutions have introduced special CT scanners into dissection rooms and carried out related research work. Postmortem computed tomography (PMCT) is more and more widely used in forensic autopsy. Although PMCT images are superior to standard radiography, they still cannot reveal detailed intravascular abnormalities. Therefore, in clinical practice, CT is used as an auxiliary means of patient examination rather than a single diagnostic tool. The rapid development of post-mortem computed tomography angiography (PMCTA) technology has made up for the above shortcomings to a large extent. It can fully present the trajectory and shape of blood vessels by using contrast agents for enhanced scanning. But postmortem angiography is ex...
