Environmentally-friendly degradable disposable medical apparatus base material and manufacture method thereof

Abstract

The invention discloses an environmentally-friendly degradable disposable medical apparatus base material and a manufacture method thereof. The environmentally-friendly degradative disposable medical apparatus base material is characterized in that the degradable macromolecule main ingredient comprises 100 parts of polylactic acid base material with a molecular weight of 2000 000 and 2-5 parts of ethylene bis stearamide. The degradable base material can be used for manufacturing the disposable medical apparatuses, such as a disposable cervical dilator, a disposable uterine probe, a disposable uterine curet, a disposable vaginal dilator, a disposable intrauterine device extractor, a disposable oviduct ligating hook and plate, a disposable cervical biopsy sampler, a disposable umbilical cord clamp, a disposable tongue depressor, a disposable instrumenta cibaria mordentia, a disposable cuffed oropharyngeal airway, a disposable anaesthetic laryngoscope, a disposable rhinoscope, a disposable ear mirror, a disposable anoscope, a disposable rectum, sigmoid flexure biopsy forceps, a disposable nasopharynx biopsy forceps, a disposable syringe pipe, a disposable surgical knife handle, and a disposable oral cavity impression tray. The used disposable medical apparatus should not be burnt and can be completely degraded through the compost treatment, so that the purposes of the environmental protection and energy conservation, the aims of environment pollution avoidance, safety and health and the mankind benefit can be reached.

Description

technical field [0001] The invention relates to the field of environmentally friendly degradable medical devices, in particular to an environmentally friendly degradable disposable medical device substrate and a manufacturing method. Background technique [0002] So far, the substrates of disposable medical devices used at home and abroad are almost all made of petroleum-based non-degradable plastics such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), ABS, and AS. However, through decades of clinical practice, it has been proved that disposable medical devices made of petroleum-based plastics do have many problems, especially the waste after use that needs to be incinerated. Now everyone knows that a large amount of black smoke generated when plastics are incinerated pollutes the environment At the same time, it will release "dioxin" and other toxic and carcinogenic substances suspended in the air. "Dioxin" is very toxic, 900 times that of arsenic. It is...

Problems solved by technology

But judging from our current research and practice, not all disposable medical device base materials made of petroleum-based plastics can be made of degradable materials, but some of them, and so far, there is no research on environmental protection by the present invention at home and abroad.
