Preparation equipment for cardiovascular imaging examination contrast agent

Abstract

The invention discloses preparation equipment for a cardiovascular imaging examination contrast agent. The preparation equipment comprises a bottom plate. The preparation equipment is characterized inthat two supporting plates are fixed to the upper side of the bottom plate, the upper ends of the two supporting plates are fixedly connected to two ends of the lower side of a cylinder respectively,one end of the upper side of the cylinder is fixedly connected to a feeding barrel, a motor I is fixed to the center of the outer side of an end cover of one end of the cylinder, the output shaft ofthe motor I penetrates through the center of the end cover of one end of the cylinder and is fixedly connected to one end of a lead screw, the other end of the lead screw fixedly penetrates through the center of a disc and is hinged to the center of the end cover of the other end of the cylinder, the lead screw is in threaded connection to a piston, grooves are formed in two sides of the piston, and guide rails are embedded into the two grooves. The invention relates to the field of preparation of the contrast agent, specifically to the preparation equipment for the cardiovascular imaging examination contrast agent. The equipment can be used for heating the contrast agent before being injected and adding and mixing a heart therapeutic drug that needs to be added quickly.

Description

technical field [0001] The present invention relates to the field of contrast medium preparation equipment, in particular, to a contrast medium preparation equipment for cardiovascular imaging examination. Background technique [0002] Contrast agent, a chemical that is injected into human tissues or organs to enhance the viewing effect of images. When hospitals do CT or MRI, they need to inject contrast agents into patients to improve the recognition of human tissue structures, so as to assist doctors in making accurate diagnoses. The most commonly used contrast agent is iopromide. Iopromide is a water-soluble low-osmotic non-ionic contrast agent. It contains 0.769g iopromide per milliliter of aqueous solution. The drug is mainly excreted by the kidneys and is commonly used in cardiovascular angiography drug. When the contrast medium is at normal temperature, it has physical and chemical properties such as high concentration, high osmotic pressure and high viscosity; if t...

AI Technical Summary

Problems solved by technology

The contrast agent is soaked in hot water, and the contrast agent bottle must be dried with a towel before use, which is inconvenient to operate; and there is a possibility of nosocomial infection such as contamination of the contrast agent

The contrast medium has a certain impact on the heart function. Before the contrast medium is injected into the human body, cardiac therapeutic drugs need to be added to the contrast medium according to the patient’s condition to balance the impact of the contrast medium on the heart function. The consistency is high, it is difficult to mix evenly with the added drugs, the contrast agent does not mix evenly with the added drugs, the concentration of the heart treatment drug in the contrast agent is different, and it is very easy to cause danger when it enters the patient's body
