Description

Pump for delivering contrast agent

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a pump for conveying contrast agents.

Background

Contrast agents are chemicals that are injected (or administered) into human tissue or organs to enhance the image viewing effect. These articles have densities above or below the surrounding tissue, and the contrast created displays images with certain instruments. Such as iodine preparation, barium sulfate, etc. commonly used for X-ray observation.

When the current contrast operation is basically operated, a catheter extends into a blood vessel or a corresponding internal cavity of a patient, then contrast agent is injected into the blood vessel or the corresponding internal cavity for contrast operation, the average dosage is 1.28 milliliter per kilogram of body, the currently used device is a needle cylinder, but the viscosity of the contrast agent is higher, the traditional push-push type needle cylinder is quite laborious to inject, the amount of the supplied contrast agent cannot be uniformly and accurately controlled, danger is easy to cause, and the contrast agent needs to be improved.
