An infusion set is a device commonly used in the medical field to administer fluids to patients. It safely and accurately delivers drugs or solutions into the patient’s body, helping them recover. Currently, there are numerous different types of infusion sets available on the market, and among them, the most common ones include three types: disposable infusion sets, light-protective infusion sets, and precision infusion sets. Today, we will briefly introduce the components and application scenarios of these three types of syringes.
[Conventional Disposable Infusion Set]
The conventional disposable infusion set is put into use after undergoing aseptic treatment. It establishes a connection channel between the vein and the liquid medication， and is a common disposable medical consumable.
Composition： Generally， it consists of a venous needle， a protective cap， an infusion hose， a drug liquid filter， a flow rate regulator， a drip cup， a bottle cap piercing device， an air filter for the intake tube， and is connected together.
Operation method： Before use， medical staff should check the disposable infusion set as required， such as the expiration date of disinfection for the infusion set and whether the packaging is leaking or otherwise abnormal. Take out the infusion set， hang the infusion bottle with the conical connector part on the infusion rod， drain to the lower end of the infusion tube， close the regulator， then insert the venous needle into the disinfected vein. After fixation， loosen the tourniquet， and adjust the flow rate.
[Light-Resistant Infusion Set]
During the infusion process， due to the different properties of the drugs， there are different requirements. For example， some anti-tumor drugs， antihypertensive sodium nitroprusside， some vasodilator drugs， some water-soluble vitamins， some anti-infective fluoroquinolone drugs， etc.， these drugs are more susceptible to light and require light-resistant infusion. To ensure that patients receive better treatment and avoid adverse reactions caused by drug deterioration， some drugs need to use light-resistant infusion sets.
[Precision Infusion Set]
A mechanical device that can precisely control the infusion speed， which can accurately control the continuous outflow of the liquid volume within a range of up to 300ml/h (1-70 drops/minute) and can adjust the flow rate arbitrarily. It is suitable for the drip infusion of advanced ward nutritional solutions and the intravenous drip of some special drugs. Clinically， it is convenient for precise control of the infusion flow rate to meet the requirements of patients for the accuracy and stability of the infusion flow rate， and the filter of the precision infusion set has a better filtering effect on impurities in the drug liquid， reducing the harm of the infusion set to the human body. Conclusion:
The above is a brief introduction to common infusion devices. Different types of infusion devices have their own advantages in different application scenarios. During use, medical staff should pay attention to disinfection and operational standards to ensure the safety of patients and the effectiveness of treatment.
