High pressure injectors are widely used in clinical cardiovascular contrast examinations, CT enhanced contrast scans and MR enhanced scans for examination and treatment. The high pressure injector can ensure that the contrast agent is concentratedly injected into the patient’s cardiovascular system in a short time, filling the examination site with high concentration. , to capture images with better contrast. At the same time, the contrast agent injection, host exposure, and film changer can be coordinated and coordinated, thereby improving the accuracy of photography and the success rate of imaging.
So how to use the high-pressure contrast medium syringe correctly? What is the operation process?
The use of high pressure injectors is a complex task restricted by many factors. The success or failure of contrast imaging is not only related to the settings of common parameters of the high pressure injector, but also related to the choice of contrast agent, patient cooperation and operating experience.
The correct operating and procedures precautions are as follows:
1. Preparation
Before using a high-pressure injector, some preparations need to be done first to ensure a smooth operation.
1. Check whether the appearance of the injector is intact and confirm that there is no damage or air leakage.
2. Check the injector’s pressure gauge to make sure it displays accurately and within the appropriate range.
3. Prepare the required injection solution and ensure that its quality meets the requirements.
4. Check the connecting parts of the injector to ensure they are tight and reliable.
2. Filling the injection solution
1. Place the container of injection solution on the injector holder to ensure that it is stable and will not tip over.
2. Open the lid of the injection container and use sterile cotton balls to clean the liquid outlet part.
3. Insert the injection syringe of the injector into the outlet part of the injection container, making sure that it is inserted firmly and not loosely.
4. Press the pressure release valve on the injector to expel the air inside the syringe until liquid flows out of the injection needle.
5. Close the pressure release valve and keep the pressure inside the injector stable.
3. Set the injection pressure
1. Adjust the pressure regulator on the injector to set the injection pressure to the desired value. Be careful not to exceed the maximum pressure limit of the syringe.
2. Check the indication on the pressure gauge to ensure the injection pressure is set correctly.
4.Inject
1. Insert the syringe injection of the injector into the site to be injected, ensuring that the insertion depth is appropriate.
2. Press the injection button on the injector to start the injection.
3. Observe the flow of the injection solution to ensure that the injection process proceeds smoothly.
4. After the injection is completed, release the injection button and slowly pull out the injection syringe from the injection site.
5. Cleaning and Maintenance
1. After the injection is completed, clean the outer surface of the injector immediately, wipe it with a sterile cotton ball, and ensure that there is no residual injection solution.
2. Remove the syringe from the injector and clean and disinfect it thoroughly.
3. Check all parts of the injector to ensure they are intact.
4. Perform regular maintenance on the injector, including replacing seals, lubricating parts, etc.
6.Precautions
1. When operating high pressure injectors, you must wear appropriate protective equipment, such as gloves, goggles, etc.
2. Be careful when operating to avoid accidentally injuring yourself or others.
3. The scope and limitations of use of injectors should comply with relevant regulations and standards, and should not exceed their design and endurance.
4. If you find any abnormality during use, you should stop using it immediately and seek professional help.
Summarize:
The operation process of a high pressure injector includes steps such as preparation, filling of injection fluid, setting of injection pressure, injection, cleaning and maintenance. During operation, you need to pay attention to safety, accuracy and maintenance points. Only correct operation and maintenance can ensure the normal operation and service life of the high-pressure injector.
