An infusion set is a commonly used medical device, which is an infusion tool for injecting a large dose of injection into the body by intravenous drip. With the development of medical technology, the current infusion tools have developed from a single ordinary infusion set to a variety of products such as precision filter infusion sets, non-PVC material infusion sets, micro-dose adjustable infusion sets, and light-proof infusion sets. With the emergence of different functional infusion sets, the clinical problem of how to choose a suitable infusion set to ensure the safety of medication is faced.

The difference between the single-use precision filter infusion set and the ordinary infusion set is that the material and pore size of the filter membrane of the infusion set are different. Ordinary infusion set is a disposable infusion set used earlier in our country. It is cheap and widely used. It uses a fiber filter membrane with a pore size of 15 microns. The fibrous membrane will fall off after encountering strong acid and strong alkaline drugs, and the pore size will become larger, causing most of the particles to enter the patient's body, resulting in vascular blockage, phlebitis, allergic reactions and adverse infusion reactions. Therefore, strong acid is used clinically. , When using strong alkaline drugs, try not to choose ordinary infusion sets, such as when using ciprofloxacin, Nimotong and other drugs.

Light-proof infusion set and drugs

The light-proof infusion set is made of medical light-proof material. Due to the particularity of the chemical structure of some drugs in clinical practice, complex reactions such as ring splitting, rearrangement, hydrolysis, polymerization, oxidation and isomerization may occur under the influence of light during the instillation process, resulting in discoloration and precipitation of the drug. The titer decreases, and even toxic substances are produced, which brings harm to human health. Therefore, these drugs should be protected from light during the infusion process, and a light-proof infusion set should be used. For example, if sodium nitroprusside is not protected from light during the infusion, it will decompose by 13.5% within 10 minutes, and the drug will change color; other drugs that need to use a light-protected infusion set include fleroxacin, pefloxacin mesylate, cisplatin Platinum, Oxaliplatin, etc.

Microdosing Sets and Drugs

The function of the micro-dose infusion set is to adjust the infusion rate, and the adjustment range is 5-250ml/h, which can meet various clinical needs. In clinical practice, some drugs such as fluorouracil, vindesine sulfate, homoharringtonine, paclitaxel liposome, etc. can be used with transverse velocity infusion set to reduce the flow rate error caused by the change of liquid level and the change of patient's position. , Correctly implement the doctor's orders, so that the patient can get effective treatment, and reduce the workload of nurses constantly adjusting the flow rate of the liquid medicine.

To sum up, in clinical practice, infusion sets with different functions must be correctly selected according to the properties of drugs, so as to prevent the damage of insoluble particles to the blood vessels of patients, reduce the occurrence of drug-induced allergic reactions, reduce the adsorption of drugs, and avoid plasticizers and heat. The potential harm caused by stabilizers to the health of patients ensures the safety and effectiveness of clinical medication.
