Problems solved by technology

[0003]Because the contrast agent has been kept in the container for a long time, after being drawn into the syringe, the contrast agent is relatively viscous, and the piston pushes resistance during injection, which is very difficult. It is difficult to control the contrast agent to enter the human body smoothly, and the safety is low. At the same time, it is difficult for the traditional injector to heat the contrast agent, which leads to the low temperature contrast agent after entering the human body, which is easy to cause discomfort to the patient.

Abstract

The invention discloses a clinical contrast injection device for cardiovascular medicine and an injection method, and relates to the technical field of injectors, the clinical contrast injection device comprises a syringe, an injection needle and a first piston plate, the lower surface of the first piston plate is fixedly connected with a piston rod, the lower surface of the syringe is provided with a first opening allowing the piston rod to penetrate through and be in sliding connection with the piston rod, the inner wall of the syringe is fixedly connected with a heat-conducting pipe, the space between the heat-conducting pipe and the syringe is filled with heat-conducting liquid, the clinical contrast injection device also comprises a heating component used for driving the heat-conduction liquid to circularly flow and rise the temperature and a switching component enabling the piston plate to move while rotating or only moving when the piston rod moves, and the heating component is in transmission connection with the switching component. The clinical contrast injection device has the effects that a contrast agent can be conveniently stirred to be sparse, meanwhile, in the stirring process, the contrast agent can be synchronously heated, and the comfort degree of a patient is improved.

Description

technical field [0001] The invention relates to the field of medical cardiovascular technology, in particular to a clinical imaging injection device and injection method for cardiovascular medicine. Background technique [0002] The contrast agent injectors currently used clinically are similar to ordinary syringes. [0003] Since the contrast agent has been placed in the container for a long time, the contrast agent is relatively viscous after being drawn into the syringe, and the piston pushes resistance during injection. It is difficult to control the contrast agent entering the human body smoothly, and the safety is low. At the same time, it is difficult for the traditional injector to heat up the contrast medium, which leads to the discomfort of the patient after the contrast medium with a low temperature enters the human body. Contents of the invention [0004] The purpose of the present invention is to provide a clinical contrast injection device and injection meth...
