Embodiment 1

[0029] figure 1 Shown is a preferred embodiment of the safe composite light-proof medical tubing of the present invention. According to this embodiment, the medical tubing has a two-layer structure: an outer layer 1 not in contact with the medical solution and an inner layer 3 in contact with the medical solution. Wherein, the outer layer 1 and the inner layer 3 are respectively made of different materials.

[0030] Among them, the inner layer 3 in contact with the liquid medicine is made of thermoplastic polyurethane elastomer (TPU) or polytetrafluoroethylene (PTFE) or polyethylene (PE) or polypropylene (PP) or polyester (PET), the thickness Between 0.03mm-0.8mm.

[0031] Preferably, the inner layer 3 of the medical tubing is made of TPU, because TPU has high wear resistance, wide hardness range, good elasticity, high mechanical strength, outstanding cold resistance, good processing performance, oil resistance, water resistance, mold resistance and recycling Good, convenie...

Embodiment 2

[0040] figure 2 Shown is a preferred embodiment of the safe composite light-proof medical tubing of the present invention. According to this embodiment, the medical tubing has a three-layer structure: an inner layer 3 that is in contact with the medical solution, an outer layer 1 that is not in contact with the medical solution, and a middle layer between the inner layer 3 and the outer layer 1 that supports the entire tube. Layer 2, wherein the materials used in adjacent pipe layers are different, that is, the materials used in the outer layer 1 and the middle support layer 2 are different, and the materials used in the middle support layer 2 and the inner layer 3 are different.

[0041] Among them, the inner layer 3 in contact with the liquid medicine is made of thermoplastic polyurethane elastomer (TPU) or polytetrafluoroethylene (PTFE) or polyethylene (PE) or polypropylene (PP) or polyester (PET), with a thickness of between Between 0.03mm-0.8mm. Preferably, the inner l...

Abstract

The invention belongs to the field of medical apparatuses, in particular to a safe composite lucifugal medical tube and a manufacturing method thereof. The safe composite lucifugal medical tube comprises two or more tube layers, wherein the adjacent tube layers are made of different materials; an inner material in contact with medicinal liquid is thermoplastic polyurethane elastomer, polytetrafluoroethylene, polyethylene, polypropylene or polyester; an outer material which makes no contact with the medicinal liquid is polyvinyl chloride, thermoplastic polyurethane elastomer, polytetrafluoroethylene, polyethylene, polypropylene or polyester; a colorant is added into the outer material. The inner layer of the safe composite lucifugal medical tube is made of a non-PVC medical polymer material, so that in the infusion process, DEHP precipitation is avoided and the safety of the safe composite lucifugal medical tube is improved; the outer layer of the safe composite lucifugal medical tube is made of a medical polymer material added with the colorant, so that the safe composite lucifugal medical tube is lucifugal in the infusion process, and the lucifugal colorant makes no contact with the medicinal liquid.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a safe composite light-proof medical pipe and a manufacturing method thereof. Background technique [0002] Some clinical drugs need to be protected from light during the infusion process, otherwise photochemical degradation, photosensitivity reactions, phototoxicity, etc. will occur. These photochemical reactions reduce the due value of the drug and even cause problems such as side effects. Such as nitroprusside, nitroglycerin, vitamin B 2 , Sandonian, codeine, etc. In clinical practice, in order to ensure the safety and reliability of its treatment, these drugs that are chemically unstable, deteriorate, change color when exposed to light, and even cause photosensitivity reactions, phototoxicity, etc., need to be protected from light during the infusion process. its therapeutic effect. [0003] Traditional light-proof medical pipes usually use medical polyvinyl chloride (PVC) p...
