1、 Working principle of infusion pump
The infusion pump precisely controls the flow rate of the infusion catheter through an internal mechanical or electronic system, thereby achieving precise adjustment of the infusion speed. It can automatically adjust the infusion speed according to the doctor's settings, ensuring that medication or nutrient solution enters the patient's body at a constant speed.
2、 Clinical application of infusion pump
The use of vasopressors: The use of vasopressors is crucial in patients with shock or hypotension. The infusion pump can accurately control the infusion speed of pressure boosting drugs, ensuring that the concentration of drugs in the body remains stable, thereby effectively raising blood pressure.
Application of antiarrhythmic drugs: For patients with arrhythmia, infusion pumps can accurately control the infusion speed and dosage of antiarrhythmic drugs, avoiding side effects caused by drug overdose or insufficiency.
Intravenous infusion for infants and young children: Due to their light weight and small blood volume, infants and young children have stricter requirements for infusion speed and dosage. The infusion pump can accurately control the infusion speed, ensuring that infants and young children will not experience adverse reactions during the infusion process.
Intravenous anesthesia: During surgery, the infusion speed and dosage of intravenous anesthesia drugs are crucial for surgical outcomes and patient safety. The infusion pump can accurately control the infusion speed of anesthetic drugs, ensuring that patients maintain a stable anesthesia state during the surgical process.
3、 Precautions for clinical operation of infusion pumps
Drug preparation: Before infusion, the medication should be prepared in the dispensing room according to the doctor's prescription, and the quality of the solution should be checked for deterioration, discoloration, turbidity, as well as loose bottle mouth and expiration date.
Aseptic operation: During the infusion process, the principle of aseptic operation should be strictly followed to avoid infection.
Adjust infusion speed: Adjust the infusion speed and volume on the infusion pump according to the doctor's instructions.
Observing patient reactions: During the infusion process, the patient's reactions should be closely monitored, and any abnormalities should be promptly addressed.
Record infusion information: Detailed records should be kept of the medication, liquid volume, infusion speed, and reasons for infusion pump alarms on the infusion pump, in order to take appropriate treatment measures in a timely manner.
