Embodiment 11

[0051] A medical AMTPS material, comprising the following raw materials in weight ratio: 70 parts by weight of styrene-butadiene-styrene block copolymer SEBS, 30 parts by weight of reinforced resin polypropylene PP, 0.055 parts by weight of green composite antioxidant ECLL , 0.1 parts by weight of slip agent, 0.01 parts by weight of anti-tack agent, and 0.005 parts by weight of antibacterial agent.

[0052] In this embodiment, the styrene-butadiene-styrene block copolymer is a hydrogenated styrene-butadiene-styrene block copolymer. The reinforced resin polypropylene PP includes isotactic polypropylene, syndiotactic polypropylene and random polypropylene.

[0053] The preparation method of the green compound antioxidant ECLL is as follows: uniformly mixing vitamin E, vitamin C, lecithin, chlorogenic acid, and isopropyl myristate in a pulverized oatmeal. Vitamin E: Vitamin C: Lecithin: Chlorogenic Acid: Isopropyl Myristate = 2:0.2:2:1:1.

[0054] The slip agent includes erucam...

Embodiment 12

[0065] A kind of medical AMTPS antibacterial material, same as embodiment 1.1, difference is, comprise the raw material of following weight ratio: styrene-butadiene-styrene block copolymer SEBS 66 weight parts, reinforced resin polypropylene PP 34 weight 0.105 parts by weight of green composite antioxidant ECLL, 0.1 parts by weight of slip agent, 0.01 parts by weight of antisticking agent, and 0.008 parts by weight of antibacterial agent. The antibacterial agent is chlorogenic acid.

Embodiment 13

[0067] A kind of medical AMTPS antibacterial material, identical with embodiment 1.1, difference is, styrene-butadiene-styrene block copolymer SEBS 62 weight parts, reinforced resin polypropylene PP 38 weight parts, green composite antioxidant ECLL 0.2 parts by weight, 0.1 parts by weight of slip agent, 0.01 parts by weight of anti-sticking agent, and 0.01 parts by weight of antibacterial agent. The antibacterial agent is an equal proportion mixture of octenidine and chlorogenic acid.

Abstract

The invention discloses a medical AMTPS material, a medical instrument and a preparation method. The medical AMTPS material comprises, by weight, 50-80 parts of styrene-butadiene-styrene segmented copolymer, 25-50 parts of reinforced resin polypropylene PP, 0.05-0.3 part of green composite antioxidant ECLL, 0.05-0.2 part of slipping agent, 0.005-0.2 part of anti-adherent or enhancer and 0.002-0.02part of antibacterial agent. A plasticizer DEHP is not added, so that damage to a patient caused by metal ions is avoided, and the medical AMTPS material is safe, nontoxic, free of drug adsorption and capable of ensuring drug treatment effect. Carcinogenic dioxin gas is not generated during burning, and performance of an injector and an infusion tube can meet using standards existing medical infusion tubes; by adding the composite antioxidant and the antibacterial agent, the medical AMTPS material has an antibacterial function, risk that the injector and the infusion tube are polluted by bacteria in the process of transportation and storage can be prevented, and safety of the patient is ensured.

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 ...
