High pressure injector is a common medical device widely used in medical fields such as imaging and interventional therapy.

1、 Basic knowledge of high-pressure injectors

A high-pressure injector is a device that can quickly inject contrast agents and other medications into human blood vessels. It usually consists of the syringe body, injection head, drug delivery pipeline, injection chamber, control system, and other parts. High pressure injectors can achieve a high-pressure state during injection to ensure that the medication quickly and evenly enters the human blood vessels in a short period of time, while reducing harm to the patient.

2、 Instructions for using high-pressure injectors

1. Preparation: Before using a high-pressure injector, it is necessary to disinfect it and confirm whether the type and dosage of medication in the injector are correct. Prepare tools such as syringes, infusion sets, disinfectants, etc.

2. Choose injection location: Select the appropriate injection location based on the desired injection site and type.

3. Connect the infusion set: Connect the infusion set to the delivery line of the high-pressure injector.

4. Set injection parameters: Based on the patient's physical condition, type of medication, and injection site, set appropriate injection parameters such as flow rate, injection time, pressure, etc.

5. Start injection: After confirming that the injection parameters are set correctly, start the high-pressure injector to start injection. During the injection process, attention should be paid to observing the patient's reaction. If any abnormal conditions such as allergies occur, the injection should be stopped immediately and corresponding measures should be taken.

3、 Precautions

1. Inspection before use: Before using a high-pressure injector, it is necessary to check whether the injector body and delivery pipeline are damaged or aged to ensure that the instrument is working properly.

2. Caution should be exercised during operation: When operating a high-pressure injector, it is necessary to strictly follow the operating procedures and precautions to avoid unnecessary injury or risk.

3. Disinfection treatment: After use, high-pressure injectors need to be thoroughly disinfected to ensure hygiene and safety for the next use.

4. Storage management: High pressure injectors need to be stored in a dry, ventilated, and non corrosive gas environment to avoid moisture and high temperatures.

The impact of harmful factors such as direct sunlight, while avoiding mixing equipment with other items or being squeezed.

5. Not suitable for: High pressure syringes are not suitable for people with allergies, heart disease, liver and kidney dysfunction, pregnant women, etc. They should be carefully selected and used according to the patient's condition.

6. Emergency preparedness: When using high-pressure injectors, it is necessary to prepare emergency response measures and medication to deal with possible abnormal situations.

4、 Maintenance and upkeep

1. Regular maintenance: High pressure injectors need to be cleaned and maintained regularly to ensure the performance and service life of the equipment.

2. Keep clean: During use, it is necessary to pay attention to maintaining the cleanliness and hygiene of components such as syringes and infusion sets to avoid risks such as contamination and infection.

3. Preventing damage: When operating a high-pressure injector, it is important to avoid damaging the instrument by collision, compression, etc., and to avoid improper disassembly and repair of the injector during use.

In short, high-pressure injectors are important medical devices that require strict adherence to operating procedures and precautions during use, as well as attention to their storage, management, and maintenance to ensure their safe and effective service to patients.
