Clinical angiograpnic injection device for cardiovascular medicine department and injection method thereof

Abstract

The invention discloses a clinical angiograpnic injection device for a cardiovascular medicine department, the clinical angiograpnic injection device for the cardiovascular medicine department comprises a bottom cavity and a connecting rod fixedly connected to the bottom cavity, wherein the top end of the connecting rod is fixedly connected with a displayer through a cross rod; and a walking part, wherein the walking part comprises a mounting cavity, a supporting rod and walking wheels; circular rings are arranged on the outer surface of the bottom cavity in an annular array mode, the multiple supporting rods are slidably connected into the circular rings respectively, the mounting cavity is fixedly connected to the lower ends of the supporting rods, the walking wheels are rotationally connected into the mounting cavity, and the walking part is used for moving the angiograpnic injection device. When a push rod and a sealing plug fixed to the push rod move downwards, liquid located on the lower side of the sealing plug flows upwards through the through hole in the sealing plug, so that the downward movement of the push rod is buffered, and the piston rod can stably and smoothly move downwards for injection.

Description

technical field [0001] The invention relates to the technical field of cardiovascular medicine, in particular to a clinical imaging injection device and injection method for cardiovascular medicine. Background technique [0002] Contrast agent is a chemical product injected into human tissues or organs to enhance the effect of image observation. Contrast agent is one of the most commonly used drugs in interventional radiology operations. It is mainly used for the display of blood vessels and body cavities. There are various types of contrast agents. Contrast agents used in interventional radiology are mostly iodine-containing preparations. [0003] With the rapid development of medicine, most of the existing clinical contrast injection devices used in cardiovascular medicine use mechanical control to push the injection when injecting patients. Because the mechanically pushed syringe will infuse, the infusion volume will be uneven and the speed will be different. , so that i...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. Most of the existing clinical radiography injection devices for cardiovascular medicine use mechanical control to push the injection when injecting patients. Because the mechanical push syringe will infuse, it will cause infusion. The amount is not smooth and the speed is different, which will affect the physical and mental health of the patient when used, and a clinical contrast injection device and injection method for cardiovascular medicine are proposed.
