Automatic high pressure injection system

Abstract

The invention discloses an automatic high pressure injection system. The automatic high pressure injection system comprises a human-computer interaction module, a data acquisition module, a control module and an injection module; the injection module includes a needle tube storage unit and a needle tube, and the injection module is used for extrude a contrast agent from the needle tube. The needle tube is placed simply and quickly and slides into a storage groove to be stacked, and the needle tube is kept warm; the needle tube is installed simply and rapidly and has the function of storage and heat preservation, and the contrast effect is improved; the needle tube is automatically replaced, and the injection effect is improved; with the automatic replacement of the needle tube, the standardized needle tube can be made into small capacity specification, the injection effect is guaranteed, the contamination or abandonment of the unused contrast agent is reduced, and the utilization rate of the contrast agent is improved; replacement of a catheter and a suction needle is completed, the injection efficiency can be improved, and meanwhile, the safety of injection is improved.

Description

technical field [0001] The invention relates to contrast agent injection equipment, in particular to an automatic high-pressure injection system. Background technique [0002] The basic function of the high-pressure injector is to quickly and accurately inject a sufficient amount of high-concentration X-ray contrast agent into the inspection site through percutaneous puncture into blood vessels or through the original pores of the human body within a certain period of time, so as to diagnose the lesion. Imaging and treatment. [0003] Due to the viscosity of the contrast medium, when the contrast medium is heated to body temperature, its viscosity will be reduced by about half, so it is easier to draw warmed contrast medium (especially high concentration preparations) into the syringe Generally speaking, there are certain differences between long-term storage and temporary storage of contrast media. When in use, because different people use different amounts, the differenc...

AI Technical Summary

Problems solved by technology

During use, due to the difference in the amount used by different people, the difference can reach several times, and it is easy to cause the unused needle tube to be discarded, resulting in a low utilization rate of the contrast medium

At the same time, the existing needle tubes and catheters need to be replaced manually, which is cumbersome and inefficient
