Embodiment 1

[0030] Example 1 The degradable anoscope is composed of an outer cylinder and an inner core, both of which are prepared from degradable polymer main materials, reinforcing agents and lubricants of the degradable base material, and the injection molding method is as follows:

[0031] The first step, vacuum drying: vacuum-dry the degradable substrate pellets of Formula 1 or Formula 2 at 50°C for 5 hours, and set aside;

[0032] The second step, injection molding: add the dried degradable substrate pellets of formula 1 or formula 2 to an injection molding machine for injection molding.

[0033] The barrel temperature is set as follows: feed inlet 155°C, compression section 165°C, metering section 170°C, nozzle 165°C;

[0034] Mold temperature: 25°C;

[0035] The injection pressure is: the first section is 75pa, the second section is 80Mpa, and the third section is 50Mpa;

[0036] Injection time: 39 seconds;

[0037] The holding time is: 0 seconds;

[0038] The screw speed is:...

Abstract

The present invention provides a degradable material for an anoscope and a preparation method thereof. The degradable anoscope is composed of an outer cylinder and an inner core. The outer cylinder and the inner core are both composed of a degradable polymer ingredient of a degradable substrate, an enhancer and a lubricant. 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 50-80 Mpa; the injection molding time is 36-39 seconds; the dwell time is 0 seconds; and the screw speed is 180 r / min. The degradable anoscope can completely replace the disposable anoscope made of polystyrene, modified polystyrene and other plastics. The waste anoscope 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 anoscope and a preparation method. Background technique [0002] At present, most of the disposable anoscopes are made of benzene, modified benzene and other materials. After use, the discarded anoscopes 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 anoscope 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...
