Abstract

The invention discloses a medical AMTPS material, a medical device and a preparation method, which include raw materials in the following weight ratio: 50-80 parts by weight of styrene-butadiene-styrene block copolymer SEBS, reinforced resin polypropylene PP 25-50 parts by weight, 0.05-0.3 parts by weight of green composite antioxidant ECLL, 0.05-0.2 parts by weight of slip agent, 0.005-0.02 parts by weight of anti-sticking agent or reinforcing agent, and 0.002-0.02 parts by weight of antibacterial agent. This application does not add plasticizer DEHP, avoids the harm of metal ions to patients, is safe and non-toxic, has no adsorption to drugs, and ensures the efficacy of drugs and other advantages. At the same time, incineration will not produce carcinogenic dioxin gas, and the performance of syringes and infusion tubes can meet the current standards for the use of medical infusion tubes. The risk of bacterial contamination of syringes and infusion tubes during transportation, storage and use ensures the safety of patients.

Description

technical field

[0001] The invention belongs to the field of medical devices, in particular to a medical AMTPS material, a medical device and a preparation method. Background technique

[0002] Polyvinyl chloride (PVC) infusion tube has the advantages of unbreakable, high transparency, no kink in normal use and good mechanical properties. For a long time, medical infusion tubes all adopt polyvinyl chloride resin (PVC) to produce at home and abroad. However, due to the relatively hard PVC material, in order to ensure the flexibility and resilience of the infusion set during the production process, it is necessary to add a plasticizer, generally DEHP (that is, dioctyl phthalate, the addition amount is about 35%-40%) ), stabilizer: heavy metal compounds containing Ca, Zn, Ba and other elements. During the infusion process, DEHP and heavy metal ions in the PVC infusion tube will be released into the liquid medicine, which will significantly increase the insoluble particles in ...
