This document outlines the specifications for the Triton-Mask developed at UC San Diego as a possible solution for PPE shortage during the COVID-19 pandemic. The Triton-Mask is an Emergency-Use Mask with a high-grade filtration and fit, comparable to standard N-95 respirators.
This product is a surgical mask. Materials that contact the body are polypropylene Halyard Sterilization Wrap, polypropylene Medline Sterilization Wrap, and elastic bands. This surgical mask meets Class I or Class II flammability requirements per 16 CFR 1610. Use this surgical mask with appropriate personal protective equipment per your institution’s standards. This product meets fluid resistance testing consistent with standard ASTM F1862 Standard Test Method for Resistance of Medical Face Masks to Penetration by Synthetic Blood.
This device has not been tested or qualified for any of the following uses: to prevent or reduce infection or related uses; for antimicrobial or antiviral protection; for radiation protection. It does not provide particulate filtration. Nor has this device been approved by any local, state, or federal agency, including the FDA. This device has not been disinfected or cleaned. Non-sterile.
The Regents of the University of California makes no claims regarding the safety and efficacy of this product. This product is delivered without warranty of any kind, express or implied, including without limitation any warranty of title, merchantability, or fitness for a particular purpose. Use it at your own risk.
We and others have identified readily available material that filters 99% of particulates according to our tests and manufacturing specifications. We designed a respirator that provides 0.01% particulate penetration during normal breathing which can be deployed for public use, however, in order to enable scaling up future production and distribution more resources are needed.
Our overall goal is to empower anyone in need in California and beyond to readily access quality respirators that enable protection from the Coronavirus. We want the general population to be able to produce, or locally obtain, face masks with filtration and fit as close as possible to the protection warranted by current standards such as the N95 respirators. To provide generalizable access across populations with varying access to tools and materials, we aim to create a number of designs for DIY respirators that can be produced easily and with various local resources such as small-scale 3D printing facilities, easy-to-find filtration material, sewing, casting and other techniques.
We have received positive feedback to continue making these DIY respirators from top leadership within various departments in the UC San Diego Health Systems such as Surgery, the Emergency Department, and Infectious Diseases. Building off the success we have had with this respirators design, we are also working on optimizing the mask shape to universally seal on all individuals’ faces and provide the seal needed for medical-grade protection. The hope here is to also alleviate the stress on resources available for healthcare workers.
