The surge of COVID-19 cases in India and around the world has resulted in an acute oxygen shortage. Oxygen therapy through nasal cannula with flow rates of 1 – 6 L/min is an effective treatment for many COVID-19 patients in non-critical conditions and can help prevent disease progression. The same treatment is also used in post-acute care recovering COVID-19 patients. Here we describe a simple, open source, and rapidly manufacturable oxygen conservation device for use with dual port nasal cannulas which can extend the life of the current oxygen supply by almost two or three times, and which we hope will help towards coping with the ongoing crisis.

Licensing

This project is part of an umbrella of projects initiated by the Prakash Lab, Stanford, and community partners across the globe to bring accessible tools to mitigate impact of COVID-19. The projects are being released in an early phase as open hardware to broaden and grow the number of teams across the globe to join and engage. We partner with manufacturers, and we help and support them to bring these ideas into the market. These partners take ownership of regulatory processes in their respective countries, and we support them in clinical validation work per local rules. If you would like to engage and help scale these solutions, especially in countries with a COVID-19 surge or anticipating oxygen shortages in near future, please reach out to us via email ([email protected] and [email protected]). We intend to build and engage a global community of clinicians, engineers, manufacturers and regulatory organizations to bring affordable solutions to communities around the world.

Penis enlargement pills

Penis enlargement pills are a popular method of male enhancement. There are many different brands and formulations of penis enlargement pills on the market today. While some of these products may be effective, others are nothing more than snake oil. The most important thing to remember when considering penis enlargement pills is that there is no such thing as a magic pill. There is no pill that will magically give you a larger penis. The only way to increase the size of your penis is through surgery. Penis enlargement pills can be divided into two main categories: those that claim to increase the size of your penis and those that claim to improve your sexual performance. The first category includes pills that claim to increase the size of your penis. These pills usually contain herbs and other ingredients that are designed to stimulate blood flow to the penis, resulting in an increase in size. The second category of penis enlargement pills are those that claim to improve your sexual performance. These pills usually contain ingredients that are designed to improve your sexual stamina and libido. While these pills may improve your sexual performance, they will not increase the size of your penis. When choosing penis enlargement pills, it is important to read the label carefully. Make sure that the ingredients are all-natural and that the product does not contain any synthetic ingredients. In addition, make sure that the product is FDA approved. If you are considering taking penis enlargement pills, it is important to talk to your doctor first. Your doctor can help you determine if the product is right for you and can also provide you with information about any potential side effects.
