Embodiment 1

[0032] Example 1 Injection molding method of degradable disposable mouthpiece:

[0033] The first step, vacuum drying: the degradable substrate pellets of formula 1, formula 2 or formula 3 are vacuum-dried at 50° C. for 3.30 hours before use.

[0034] The second step, injection molding: add the dried degradable substrate pellets of formula 1, formula 2 or formula 3 to an injection molding machine for injection molding.

[0035] The barrel temperature is set to: 150°C for the feed port, 160°C for the compression section, 170°C for the metering section, and 165°C for the nozzle;

[0036] The mold temperature is: 25℃;

[0037] The injection pressure is: 75pa for the first section, 80Mpa for the second section, and 50Mpa for the third section;

[0038] Injection time: 40 seconds;

[0039] Holding time: 0 seconds;

[0040] The screw speed is: 180 rpm.

[0041] A degradable disposable mouthpiece using the degradable base material of formula 1, formula 2 or formula 3 is obtained...

Abstract

The present invention provides a degradable disposable mouthpiece and a preparation method. The degradable disposable mouthpiece is prepared by 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 of 160-185 DEG C, a metering section of 165-175 DEG C, a nozzle is of 160-170 DEG C, the mold temperature is 20-30 DEG C, the injection pressure is 45-90 Mpa, the injection time is 38-41 seconds, the dwell time is 0 sec, and the screw speed is 180 rpm. The performances of the degradable disposable mouthpiece are in line with the requirements of medical apparatus and instruments. The degradable disposable mouthpiece can completely degrade by landfill in the natural environment after being used without burning to achieve low-carbon, energy-saving, and environmental protective purposes.

Description

technical field [0001] The invention relates to the field of disposable medical instruments, in particular to a degradable disposable mouthpiece and a preparation method. Background technique [0002] Clinically, when performing gastroscopy or gastric lavage, instruments such as gastroscope and gastric lavage need to be inserted into the patient's esophagus. These very hard instruments enter and exit the cavity or bite consciously or unconsciously when the patient feels pain, which is easy to cause damage to the teeth. damage, in order to protect the patient's teeth, so someone invented a "disposable mouth bite device", searched domestic patents, there is a "a kind of mouth guard mouth device" with a utility model patent number of 200720091217.3, but for a long time, the "mouth bite device" They are all made of plastic materials, and the mouthpieces after use need to be disposed of by centralized incineration. When plastic is incinerated, a large amount of black smoke will b...
