Abstract

The present invention provides a degradable material for otoscope and a preparation method thereof. The degradable otoscope is composed of a degradable polymer main ingredient of a degradable substrate and an enhancer. The injection molding process includes that: a feed inlet is of 150-165 DEG C, a compression section is of 155-165 DEG C, a metering section is of 160-175 DEG C, a nozzle is of 165-175 DEG C; the mold temperature is 20-35 DEG C; the injection pressure is of 50-80 MPa; the injection time is 36-39 seconds; the dwell time is 0 sec; and the screw speed is 180 r / min. The degradable otoscope is up to the requirements of clinical use in performances, and can completely replace ABS plastic disposable otoscope. The waste otoscope cannot pollute the environment by burning, and can completely degrade in the natural environment by landfill to achieve purposes of low-carbon, environmental protection, and energy saving.

Description

technical field [0001] The invention belongs to the field of degradable disposable medical devices, in particular to a degradable material for an otoscope and a preparation method thereof. Background technique [0002] At present, most disposable otoscopes are made of polyvinyl chloride, ABS and other materials. After use, the discarded otoscopes cannot be degraded in the natural environment and become medical waste. The current practice is to use centralized incineration. This method not only It violates the principle of sustainable development of resources, and when plastic is incinerated, it will produce a large amount of toxic black smoke, hydrogen chloride gas and strong carcinogenic dioxin, which seriously pollutes the environment and damages the health and life of humans, animals and plants. And with the otoscope that metal such as stainless steel etc. are made, repeated use easily causes cross-infection of disease, and use patient and doctor all can feel the defects ...
