TPE infusion set
TPE infusion set is mainly made of TPE material. TPE does not contain DEHP and does not adsorb drugs.
TPE material is completely non-toxic as there is no use of any chemical additives or plasticizers.
TPE is a non-polar material that does not adsorb drugs, ensuring the accuracy and therapeutic effect of medication.
Advantages of TPE infusion sets:
TPE infusion sets do not contain any small molecule compounds or additives that may pose potential hazards to the patient’s health or add new pathogenic risks during the treatment process.
TPE infusion set scope of use–
Sensitive populations such as newborns, infants, and young children;
Men before youth, pregnant and lactating women;
Severely ill patients, postoperative patients, elderly patients, tumor patients, hematological patients, long-term infusion patients.
