3D printing medical mask

Abstract

The invention discloses a 3D printing medical mask, which comprises a face side contacting with a face and an instrument side contacting with an instrument. The face side is characterized by obtaining personalized data for three-dimensional reconstruction through face scanning, and generating a face-shape-fit face side 3D data file; the instrument side is characterized by carrying out scanning on a conventional mask to obtain data for three-dimensional reconstruction, or carrying out correction according to clinical requirements to obtain a 3D data file; by jointing the 3D data files of the face side and the instrument side, a 3D printing mask digital file is formed; and finally, a personalized 3D printing medical mask is generated through printing of a 3D printer. The 3D printing medical mask subverts a conventional mask making method, is fit to the face shape of a person, solves the problem of side leakage of the air, can be more effectively applied to the breathing machine and cardiopulmonary exercise test of a patient, can be fit to the face shape of an animal in a personalized manner, and can be applied to respiratory disease treatment and of the animal and clinic animal experiment.

Description

technical field [0001] The invention relates to the technical field of medical masks, in particular to a 3D printed medical mask. Background technique [0002] 3D printing is based on digital model files. First, it is modeled by computer modeling software, and then the built three-dimensional model is "divided" into layer-by-layer sections, and the printer is instructed to use powdered metal or plastic and other bondable materials. The technology of constructing objects by printing layer by layer. Commonly used materials are plastic, nylon, photosensitive resin, gypsum, titanium alloy, rubber and other materials. Currently commonly used printing methods include fused deposition modeling technology, selective laser sintering technology, multi-nozzle molding technology and three-dimensional printing. [0003] In 1986, Charles Hull developed the first commercial 3D printing machine, and the technology has been in development for nearly 30 years. It was first used to make mod...

Problems solved by technology

[0005] At present, the respiratory masks provided clinically are often prefabricated and divided into three types: large, medium and small. However, due to the different shapes of people's faces, the masks often cannot completely cover the face, so patients often have air leakage during breathing. Phenomenon

[0006] 1) In the application of the ventilator, oxygen leakage will occur, and the patient cannot effectively inhale oxygen

Due to air side leakage, the airway pressure of the ventilator cannot be effectively adjusted, which will affect the parameter adjustment of the ventilator, and then affect the therapeutic effect of the ventilator on patients

[0007] 2) In the cardiopulmonary exercise load test, due to air side leakage, the outside air enters the airway, which affects the concentration of oxygen and carbon dioxide in the airway, thus affecting the results of the exercise load test

[0008] Animals such as dogs and rabbits do not have special breathing masks, so it is difficult to carry out corresponding treatments and experiments
