N95 Decontamination for Reuse through Convective Heating

The current COVID pandemic has resulted in personal protective equipment shortages. Scaling up to new demand takes manufacturing development time demanding for DIY methods for N95 decontamination. We report a dry heat design solution that can be used to deactivate COVID-19 in N95 face masks enabling mask reuse.


Operation Ventilation: A Ventilator Training Web Application

Hospitals need to train HCPs for ventilator operation to increase the number of available trained personnel and the capacity of ventilator care. We built a mobile-accessible web app where HCPs can learn to operate the 7 different models of mechanical ventilators and change the 5 main settings on each model.

mPAPR: an AdHoc Solution to PPE Shortage Using Compressed Medical Air

Healthcare providers are running out of PPE. To help conserve traditional PPE, we propose the usage of PAPR masks and hoods connected via air hoses to hospital pressurized air wall supplies in ICUs and operating rooms. This form of PPE would be inexpensive, reusable, and easily scalable.

CovidSMS was created by a group of Stanford and Johns Hopkins students who identified a need for streamlined local communication as a result of the COVID-19 crisis. The platform provides an accessible method for community members to stay up-to-date with local information and for city officials to share updates, ask questions, and collect community feedback. We have currently partnered with San Marino, CA, and we are seeking out new cities whose communities may benefit from CovidSMS.

Handless - Opening doors one foot at the time

Viruses survive for hours on surfaces, where it can then be transferred and infect anyone by touch. Our goal is to reduce sources of contamination and slow down the spread of viruses with Handless; a modular door handle attachment that enables users to unlatch and open doors by using one foot.

Healthcare workers are battling COVID-19 on the front lines. As nurse practitioners we recognize the need to provide recommendations for a decontamination routine. “S.C.R.U.B.S,” a documentation guide communicates a process to prevent transmission and relieve anxiety among health-care workers.

Our alternative to in-person lines for grocery stores to reduce social crowding is a mobile app that allows users to wait in a mobile line in the comfort of their homes and avoid unnecessary infection risks from crowded lines. Additional functionality lets users schedule times to go to the store, allowing them to bypass the queue.

Though social distancing is shown to reduce viral transmission, people continue to meet in high densities for essential services. We developed an app to alleviate this concern in grocery stores by compiling data on real-time store traffic, max capacities and item inventory, protecting the health and satisfaction of both customers and employees.
