Single-cylinder CT high-pressure injector auxiliary pipeline device, CT high-pressure radiography equipment and using method of CT high-pressure radiography equipment

Abstract

The invention relates to the technical field of medical instruments, in particular to a single-cylinder CT high-pressure injector auxiliary pipeline device, CT high-pressure radiography equipment anda using method of the CT high-pressure radiography equipment, and aims to realize rapid and accurate switching of a contrast agent and normal saline at any time and remarkably reduce excessive use ofthe contrast agent. The auxiliary pipeline device comprises an electromagnetic control device and a double-Y-shaped pipeline system, the electromagnetic control device comprises a base, an electromagnetic push rod assembly and an upper cover, a strip-shaped groove is formed in the middle of the base, and an electromagnetic push rod in the electromagnetic push rod assembly is arranged in the strip-shaped groove; the left end and the right end of the strip-shaped groove are provided with a first pipe groove and a second pipe groove respectively, and the first pipe groove and the second pipe groove are parallel. The double-Y-shaped pipeline system comprises an input end connected with the single-cylinder CT high-pressure injector, an output end connected with the remaining needle, a first infusion tube and a second infusion tube, the input end and the output end are both communicated with the first infusion tube and the second infusion tube, and the first infusion tube and the second infusion tube are correspondingly placed in the first tube groove and the second tube groove.

Description

technical field [0001] The invention relates to the technical field related to medical equipment, in particular to a single-tube CT high-pressure injector auxiliary pipeline device, CT high-pressure imaging equipment and a use method thereof. Background technique [0002] In recent years, with the popularization of high-end CT equipment, CT high-pressure contrast examination has been widely used in clinical blood vessel or organ enhancement examination due to its fast scanning, clear image, convenience and quickness, and has made a significant contribution in the diagnosis of diseases. contribute. In CT contrast examination, in order to obtain an accurate grasp of the enhancement phase and facilitate the diagnosis and treatment of lesions, it is necessary to use high-pressure contrast equipment to inject contrast medium quickly. It will cause extravasation of contrast medium and bring adverse consequences to patients. Therefore, in order to prevent extravasation of contrast...

Problems solved by technology

In CT contrast examination, in order to obtain an accurate grasp of the enhancement phase and facilitate the diagnosis and treatment of lesions, it is necessary to use high-pressure contrast equipment to inject contrast medium quickly. It will cause extravasation of contrast medium and bring adverse consequences to patients. Therefore, in order to prevent extravasation of contrast medium, it is best to try injecting normal saline before injecting contrast medium; It is also necessary to follow up with an appropriate amount of normal saline; ③Due to individual differences, the contrast dose required by each person is different, especially for angiography, generally only 50ml~80ml is needed, but most hospitals currently use contrast medium quantitatively, and injections need to be set in advance dose

At present, the CT high-pressure imaging equipment used at home and abroad still has the following shortcomings: 1. Single-cylinder high-pressure injectors, such as Figure 4, the contrast agent can only be used alone, and normal saline cannot be used, and trial injection cannot be done, which cannot well meet the clinical needs; 2. Even if the double-barreled high-pressure injector can simultaneously Contrast medium and normal saline are used, but the two cannot be switched quickly, and the injection of contrast medium cannot be stopped in time. We can only wait for the set contrast medium to be injected and then inject normal saline, which will cause some patients to inject unnecessary contrast medium. , which may increase the risk of allergic reactions or contrast nephropathy
