Novel rapid medicine pushing tee joint for enhanced CT and using method of novel rapid medicine pushing tee joint

Abstract

The invention provides a novel rapid medicine pushing tee joint for enhanced CT and a using method of the novel rapid medicine pushing tee joint. The novel rapid medicine pushing tee joint for enhanced CT comprises a 'Y'-shaped three-way tube body, wherein the three-way tube body comprises a main tube, a first branch tube and a second branch tube; one end of the main tube, one end of the first branch tube and one end of the second branch tube communicate with one another; a heparin cap is arranged at the outer end of the main tube; and a sealing head cap and a fixing buckle cap are separately arranged at the outer ends of the first branch tube and the second branch tube. Compared with the traditional tee joint, the novel rapid medicine pushing tee joint for enhanced CT has the characteristics that the flowing directions of the medicine are different, and single liquid enters a human body through different channels. The medicine pushing flow speed of the novel rapid medicine pushing tee joint for enhanced CT is twice greater than that of the traditional single-channel high-pressure injector, and therefore, the circumstance that enhanced CT examination cannot be carried out due to vascular factors is solved. The risk of enhanced CT leakage is reduced on the basis of meeting the requirement of enhanced CT medicine pushing speed; the novel rapid medicine pushing tee joint for enhanced CT is particularly used for radiography during imaging of veins of both lower extremities, and the dosage of drugs for a patient, the radiation dosage and the medical cost can be reduced, and the examination time is shortened. The novel rapid medicine pushing tee joint for enhanced CT belongs to the field of medical equipment.

Description

technical field [0001] The invention relates to a medicine pushing tee and a method for using the same, belonging to the field of medical tools. Background technique [0002] Enhanced CT is also called enhanced CT. It refers to a means to focus on the suspicious parts found on the basis of CT plain scan after intravenous injection of contrast agent, so as to improve the accuracy of diagnosis. Intravenous injection of contrast agent is It is an indispensable link, and generally a single-channel high-pressure syringe is used for bolus injection. However, there are many factors that affect the enhancement effect. The most important factors are the amount of contrast agent, delay time, injection speed, etc. Among them, the controllable factors include contrast agent The amount, delay time, and bolus injection speed sometimes cannot reach the drug injection speed required for enhanced CT due to the limitation of the patient's vascular factors, thus affecting the enhanced CT resul...
