Understanding the matters related to infusion sets can make infusion more reassuring
1、 What is an infusion set?
Infusion set is a common medical device product that has undergone aseptic treatment and is used to establish a channel between veins and medication for intravenous infusion. Generally, it consists of eight parts connected by intravenous or injection needles, needle caps, infusion hoses, liquid filters, flow rate regulators, drip pots, bottle stopper punctures, air filters, etc. Some infusion sets also have injection parts, medication ports, etc.
2、 What are the common types of infusion sets?
With the development of medical technology, infusion sets have evolved from single ordinary disposable infusion sets to various types such as precision filtration infusion sets, non PVC material infusion sets, flow setting fine-tuning infusion sets, hanging bottle infusion sets (bag infusion sets), burette infusion sets, and light shielded infusion sets. Here are several common types of infusion sets.
（1） Ordinary disposable infusion set and precision filtration infusion set
The ordinary infusion set is the earliest disposable infusion set used in China, which is cheap and widely used. The material used is fiber filter membrane, with a pore size of about 15 μ m. The disadvantage is that the pore size is large, the filtration efficiency is low, and the fiber filter membrane will fall off and form insoluble particles when exposed to acidic or alkaline drugs, which may enter the patient's body and lead to capillary blockage and infusion reactions. Therefore, when using strong acid and strong alkaline drugs in clinical practice, ordinary infusion sets should be avoided as much as possible.
Precision filtration infusion set is an infusion set capable of filtering particles with a diameter of 5 μ m or smaller. It has the advantages of high filtration accuracy and does not produce foreign objects falling off. It can effectively filter particles, reduce local irritation, and prevent the occurrence of phlebitis. The selected filter membrane is a nuclear pore membrane, which has a double-layer filtration medium, strong pollutant holding capacity, regular filter pores, and low drug adsorption properties. Suitable for pediatric patients, elderly patients, cancer patients, cardiovascular disease patients, critically ill patients, and patients who require long-term intravenous infusion.
（2） Fine tuning infusion set and burette infusion set
Fine tuning infusion set: commonly known as disposable micro setting fine tuning infusion set, this product is a specially designed infusion set for regulating the flow rate of medication. Using a regulator to control precise flow, fully utilizing the effectiveness of the medication, and reducing adverse reactions caused by excessive infusion to the human body.
Burette infusion set: The product consists of a bottle stopper puncture device protective cover, a bottle stopper puncture device, an injection part, a graduated burette, a shut-off valve, a dropper, a liquid filter, an air filter, a pipeline, a flow regulator, and other optional components. Suitable for pediatric infusion and situations where precise control of infusion dosage is required.
（3） Hanging bottle and bag infusion sets
Hanging bottle and bag infusion sets are used for intravenous infusion of medication in patients who require high-dose dispensing, with the main purpose of separating and infusing. Specifications and models: 100ml, 150ml, 200ml, 250ml, 300ml, 350ml, 400ml.
（4） Light shielded infusion set
The light shielding infusion set is made of medical light shielding materials. Due to the unique chemical structure of some drugs in clinical practice, complex reactions such as ring splitting, rearrangement, hydrolysis, polymerization, and oxidative isomerization can occur during the infusion process under the influence of light, resulting in drug discoloration, precipitation, decreased drug potency, and even the production of toxic substances, posing a threat to human health. Therefore, these drugs need to be protected from light during the input process and use light shielded infusion devices.
3、 What are the precautions for using infusion sets?
(1) Can only be used for gravity infusion.
(2) When the product fails or the packaging is damaged, it is strictly prohibited to use it.
(3) Disposable, ready to use upon opening, destroyed after use.
(4) 20 drops of distilled water are equivalent to 1ml ± 0.1ml.
(5) The suitable operating temperature is 10-40 ℃.
(6) The storage and transportation of products should pay attention to moisture resistance, heat resistance, sun protection, pressure resistance, etc.
4、 How to use infusion sets correctly?
(1) Before use, the packaging should be checked for any damage and the protective sheath should not come off, otherwise it is not allowed to be used.
(2) Close the flow regulator, remove the sheath of the puncture device, insert the puncture device into the infusion bottle, open the air inlet cap (or insert the air inlet needle).
(3) Hang the infusion bottle upside down and squeeze the dropper by hand until the medicine enters about 1/2 of the dropper.
(4) Release the flow regulator, place the liquid filter horizontally, exhaust the air, and you can start infusion.
(5) Before use, tighten the infusion needle connector to prevent leakage.
(6) The infusion operation should be carried out and monitored by professional nursing personnel.
5、 What are the common adverse events of infusion sets?
During the use of infusion sets, adverse events such as rupture, leakage, blockage, foreign objects, needle cap detachment, chills, and fever may occur due to product quality issues or insoluble particles.
6、 How to report adverse events of medical devices?
Medical device operating enterprises and users who discover or become aware of suspicious adverse events of medical devices shall promptly inform the registrant (filer) and report them through the National Medical Device Adverse Event Monitoring Information System. If an individual discovers adverse events of medical devices that cause or may cause serious injury or death, they can report to the drug adverse reaction monitoring agency in their jurisdiction.
