Oral mucositis is an inflammation that affects the mucosa in the mouth. It often affects patients undergoing chemotherapy for cancer. The risk of inflammation can be reduced by cooling the mouth. In this project, ten different mouthpieces for cryotherapy of the oral cavity with air as cooling medium have been modeled in the SolidWorks. Flow simulations have been made on the different mouthpieces to investigate how the air is distributed in the models. The goal of the simulations is that the outflow of air should not differ more than 10 % between the largest and the smallest flow. With the results, the mouthpieces could be fine-tuned. Flow simulation on the ten prototypes gave varying results, some have a good distribution of air between the holes. Some, however, do not evenly spread the air and it flows much less air through certain holes. Three prototypes were printed in hard plastic at an early stage to see how they fit the mouth. At the end of the project, a total of seven models were printed by TADA medical's partner in a softer plastic. Several models then showed some points that need to be considered when designing nozzles. A handful of the models have been tested with the cooling device and the flow has been examined with a heating camera. The other prototypes have not been 3D-printed, so there is nothing about their convenience. To get better results, more advanced simulation requires the environment of the oral cavity with the exact dimensions.
