Clinical Application Of High Pressure Syringes
May 25, 2017

High Pressure Syringes as medical imaging systems in the auxiliary equipment, with the X-ray machine, quick film machine, image intensifier and artificial contrast agent and the development of the gradual emergence.

A, cardiovascular angiography:

For the head and neck limbs arteries, liver and kidney artery, bronchial artery, iliac artery and vein angiography in the absence of high-pressure syringe, you can manually push the contrast injection, the disadvantage is that the operator to accept more radiation. The heart and aorta and other macrovascular imaging, especially aortic angiography and retrograde arteriography, requiring a short period of time into a large number of contrast agent, was not diluted by blood, get good quality of the film, must rely on High Pressure Syringes The High pressure injection contrast agent flow rate is generally required to reach 15 ~ 25ml / s, and the syringe start switch and X-ray camera device linkage. A high pressure injector can inject a large amount of contrast medium above the rate of blood flow dilution in a short period of time to achieve the desired concentration for development. Therefore, the high-pressure syringe is an indispensable device in cardiovascular angiography, it can ensure that in a very short period of time will focus on the injection of the patient's cardiovascular, high concentration of the test site to fill the better contrast image. High-pressure syringe can also make contrast agent injection, the host exposure of the two coordination, thereby enhancing the accuracy of photography and angiography success rate. It can be remotely controlled, so that all the staff in the photography to leave the radio site, improve the working conditions. It is the invention and development of high-pressure syringes, so that interventional cardiovascular angiography and treatment has made great progress.

B, CT enhanced contrast scan:

The previous manual hand-push CT enhanced scan can not accurately control the contrast agent injection speed, injection dose is not uniform, and need a larger push force, the impact of many factors. Routine injection after the completion of scanning, often caused by the development of arterial phase has been, to strengthen the effect of poor, less than the diagnosis of a variety of lesions. CT enhanced scan using high-pressure syringe is simple, time-saving and effort to reduce the amount of contrast agent; at the same time flow, flow rate and pressure can be set according to the different settings, can be used to scan at two speeds to maintain the concentration of contrast medium, Especially with the multi-slice spiral CT dynamic scan and CT angiography, more to show the characteristics of arteries and lesions, in order to provide a reliable diagnosis of reliable imaging basis. And high-pressure syringes also with automatic heating device, can reduce the occurrence of contrast agent side effects. But because of high pressure injection of liquid flow rate, a short period of time the flow of high blood pressure, heart disease, kidney disease patients with special attention should be appropriate to reduce the pressure and flow rate; and the use of high-pressure syringe injection can not be timely detection and treatment A small number of patients with toxic side effects and contrast agent spill and so on. In any case, the widespread use of high pressure syringes can provide the necessary means for the progress of CT scanning and imaging diagnostic methods.

C, MR Enhanced scan:

The magnetic resonance high pressure injector is designed for use with magnetic resonance imagers and is capable of working in a strong magnetic field environment. Since the osmotic pressure of the magnetic resonance contrast agent is lower than that of the iodine contrast agent, the total amount of contrast agent injection required is also small, so it is safe to enhance with the High Pressure Syringes. Application of magnetic resonance High Pressure Syringes can accurately preset the enhancement site, injection speed, angiography lump sum and delay time. And the application of high-pressure syringes facilitates the realization of fast breath-hold scanning.
