Acist Medical System is the world leader in the production of contrast systems for angiography. It was the company Acist Medical Systems that introduced the concept of "variable flow" into the process of X-ray endovascular interventions, which allowed replacing the manual introduction of contrast in coronary angiography, using an automatic injector. This made coronary angiography much safer and more effective, allowed to reduce the dose of contrast administered and, as a consequence, reduced the likelihood of development of contrast-induced nephropathy.
The company Acist Medical Systems was founded in 1991 and now more than 10 million procedures are performed worldwide with the help of Acist CVi inverters.
Description:
Injector of contrast with CVi technology is a universal, fully automatic contrast system for any operations and angiographic studies - ventriculography, peripheral vascular angiography, coronary angiography, fistulography, etc., as well as angioplasty of the coronary and peripheral arteries.
The essence of the "variable flow" technology is the ability to vary the intensity of the contrast flow in a wide range of values by means of the touch control panel of the mechanical piston, which is in the operator's hand.
Injector of contrast with CVI technology works with a reusable bulb, which is installed once at the beginning of the working day.
The function of automatic bulb filling with contrast allows one large bottle with contrast to be used during many procedures in a row, thereby reducing the contrast waste. Automatic valve switching the supply of contrast and saline by default opens the line of saline, and only after pressing the operator on the remote opens a high pressure line for contrast. For each patient, a sterile disposable kit is used from the high-pressure line for contrast and accessories for its connection.
Clear menu:
- Maximum FLOW - Displays the maximum flow rate (ml / sec) that can be obtained when the hand controller is fully pressed
- Maximum VOLUME - Displays the total amount of contrast limit that can be entered during the procedure
- Maximum PRESSURE - Displays the maximum allowable system pressure (PSI) at the injection time
- RISE TIME - reflects the time to reach the maximum contrast flow rate when the controller button is fully pressed
Benefits:
- The ability to adjust the intensity of the contrast flow with simultaneous visual control makes it possible to obtain a high-quality image with a minimum amount of contrast, sufficient for each specific case. The injectors used up to now allow performing the contrast control program established before the procedure and do not allow reducing the speed and volume of the input contrast directly during the research while achieving sufficient image quality. Thus, there is usually an excessive contrast.
- In addition, the "waste" of contrast is completely absent due to the multiple use of the flask - unused contrast remains in the reusable flask and is used during the following procedure. Using an injector with variable flow technology provides a contrast economy of 10% with angioplasty up to 39% with diagnostic catheterization. In addition to the direct and significant economic effect of reducing costs for the purchase of contrast agents, it is important to reduce the risk of contrast-induced nephropathies (CIN) and other complications directly related to the volume of the contrast procedure being introduced on time.
- Due to the need to install the system only once a day, and using a reusable flask in combination with a disposable sterile set of trunks and other accessories, the preparation time for the procedure is reduced by 50%, and the time for fluoroscopy is reduced by 25%.
- The use of a contrast injector with CVI flow technology instead of manual syringe injection allows the use of smaller diameter angiographic catheters (4 Fr) without compromising image quality and more extensive use of transradial access not only for diagnostic studies but also for coronary angioplasty.
- The contrast injector with variable CVi technology reduces radiation exposure by reducing the time of the procedure and the ability to distance itself from the radiation source.
- The contrast injector with CVi variable flow technology is equipped with an invasive pressure sensor that is installed on the brine flow line and allows the measurement of pressure in the coronary sinus during angioplasty.
- The contrast injector with CVI technology is synchronized with all known models of angiographic complexes.
