Abstract

The invention discloses a disposable degradable PPC (polypropylene carbonate) modified medical material. The medical carbon dioxide composite material comprises the following components in parts by weight: 20-70 parts of a medical carbon dioxide copolymer, 10-30 parts of polylactic acid, 40-50 parts of poly adipic acid / terephthalic acid succinic acid, 5-10 parts of an antibacterial modifier, 1-5 parts of a flame retardant, 1-5 parts of an anti-aging agent, 2-8 parts of a tackifier, 3-5 parts of a plasticizer and 1-3 parts of an end-capping reagent, the invention also discloses a preparation method and application of the medical material, and the disposable degradable PPC modified medical material disclosed by the invention has wide application prospects in the aspect of manufacturing disposable medical consumables, including degradable disposable throat swabs, samplers, disposable syringes, disposable infusion apparatuses, blood transfusion apparatuses, blood bags, urethral catheters, drainage tubes and the like. And disposable surgical instruments such as a needle holder, tweezers, a surgical knife handle and some special fixing devices in an operation.

Description

technical field [0001] The application relates to the field of medical devices, in particular to a disposable degradable PPC modified medical material and a preparation method and application thereof. Background technique [0002] With the rapid development of my country's economy, the continuous improvement of medical level, and the continuous expansion of medical services, the clinical application of disposable non-degradable medical supplies has led to an increasing number of medical solid wastes. The main treatment method is incineration, causing serious secondary pollution to the environment. . [0003] In recent years, an emerging material, namely carbon dioxide copolymer (hereinafter referred to as PPC), has emerged. Since its inception, PPC has attracted much attention because it can efficiently utilize carbon dioxide and solve the "white pollution" problem of plastics. In addition to its good barrier properties, oxygen barrier properties, and complete biodegradabili...
