Degradable material and preparation method for anesthesia laryngoscope

Abstract

The present invention provides a degradable material for anesthesia laryngoscope and a preparation method. The anesthesia laryngoscope 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 150-165 DEG C, a compression segment is of 160-165 DEG C, a metering section is of 165-175 DEG C, a nozzle is of 165-175 DEG C, the mold temperature is 20-35 DEG C, the injection pressure is 45-100 MPa, the injection time is 51-56 seconds, the dwell time is 0 sec, the screw speed is 180 rpm. The performance of the obtained anesthesia laryngoscope is in line with requirements of the national industry standard YY0499-2004 anesthesia laryngoscope general technical conditions. The used anesthesia laryngoscope can completely degrade by landfilling in the natural environment without burning to achieve low-carbon, energy-saving and environmental protection purposes.

Description

technical field [0001] The invention belongs to the field of environment-friendly, energy-saving and degradable disposable medical devices, in particular to a degradable material for anesthesia laryngoscope and a manufacturing method. Background technique [0002] "Anesthesia laryngoscope" for insertion into the throat for anesthesia or rescue of suffocation is an essential medical device in the hospital operating room. Currently, the "anesthesia laryngoscope" used in the hospital is made of stainless steel and the other is ABS. And other plastic products, the defect of the former is that it is expensive, and it is easy to cause cross-infection of iatrogenic diseases after repeated use; the latter needs to be recycled after being discarded and then incinerated. First, it pollutes the environment, but it is very wasteful, and third, it is poisonous gas Damage to human health, etc. Therefore, the research and development of degradable materials and manufacturing methods for an...

[0002] "Anesthesia laryngoscope" for insertion into the throat for anesthesia or rescue of suffocation is an essential medical device in the hospital operating room. Currently, the "anesthesia laryngoscope" used in the hospital is made of stainless steel and the other is ABS. And other plastic products, the defect of the former is that it is expensive, and it is easy to cause cross-infection of iatrogenic diseases after repeated use; the latter needs to be recycled after being discarded and then incinerated. First, it pollutes the environment, but it is very wasteful, and third, it is poisonous gas Damage to human health, etc. Therefore, the research and development of degradable materials and manufacturing methods for anesthesia laryngoscopes can not only completely avoid incineration after use, but also avoid environmental pollution and protect human health. It is both environmentally friendly and energy-saving

But so far, there is no research and report on degradable materials and preparation methods for anesthesia laryngoscope at home and abroad.
