High pressure injector is a medical device mainly used to inject liquid drugs or contrast agents into deep tissues or blood vessels of the human body for the diagnosis or treatment of diseases. High pressure injectors can provide high pressure and precise control of drug flow rate, making them an essential tool in modern medical fields.

The main parts of a high-pressure injector include the injection gun, infusion tube, controller, and injector head. The injection gun is the core component of a high-pressure injector, mainly composed of a piston and an injector head, which can control the flow rate and pressure of liquid drugs through a controller. The infusion tube transports liquid medication from the container to the injection gun. The controller is responsible for controlling the flow and pressure of the high-pressure injector to ensure the accuracy and safety of the injection.

The use of high-pressure injectors requires professional training for medical personnel and strict control of operating procedures. Before use, medical personnel need to inspect the syringe to ensure that the equipment is in normal working condition. When injecting, medical personnel need to choose appropriate syringe heads and flow control parameters, and ensure that the position and depth of the syringe are correct to ensure the safety and effectiveness of the injection.

The use of high-pressure injectors is very extensive, including various medical fields such as cardiovascular imaging, vascular intervention therapy, CT scanning, MRI, etc. Through high-pressure injectors, medical personnel can quickly inject drugs into the patient's body, reducing treatment time and pain, and improving treatment effectiveness.

In summary, a high-pressure injector is a medical device primarily used to inject liquid drugs or contrast agents into deep tissues or blood vessels of the human body for the diagnosis or treatment of diseases. It can provide the function of high pressure and precise control of drug flow rate, and is one of the indispensable tools in the modern medical field. However, due to the high-pressure nature of high-pressure injectors, extra caution is required when using them to avoid accidents.
