Heritage Students Win First Place in UC Berkeley Bioengineering Honor Society Competition | Features

Working in groups of four to five, high school students explore and investigate bioengineering, allowing students to tackle a health problem and solution in a seven-week competition.

The team won with their presentation of a new jet injection system, which is intended to help solve the problems of people who use needles frequently, but who have medical problems.

“For people who now have to use needles on a daily basis, this new system is a game-changer,” Heritage High School teacher Alexandria Dorsaneo said in an email. “When they bring this to market, we won’t need to use needles for injections anymore.”

“BioEHSC offers students the opportunity to immerse themselves in a new field of study,” Dorsaneo said. “For much of the team, bioengineering was not on our radar before the competition. We were able to get a glimpse of how advancements in technology affect our medical abilities. learned to work as a team, respecting the schedules of our teammates, and all while being pressed for time.”

World health organizations confirm how the problem of reusing needle injection equipment and accidental needlestick injuries contribute to a variety of blood-borne viruses, such as HIV and HBV. The World Health Organization has confirmed that 16 billion injections using reused needles contribute to 40% of infections.

“We wanted to tackle an important current issue regarding blood-borne diseases,” Dorsaneo said. “We have been motivated by the COVID pandemic to help solve one of the biggest problems when it comes to vaccines.”

Heritage’s new jet injection system includes a needleless disposable injection cartridge; sealed during manufacturing processes to reduce needle contamination, as well as surface-to-surface transmission by ejecting cartridges after each use into a biohazard container. The system features a two-part cartridge with compressible and incompressible fluid jets to create a reservoir in the skin to allow all medications to be ejected quickly and efficiently depending on the force used.

“What made our presentation unique was the integration of Computer Aid Design. Not only did we show schematics, but we also presented simulations to the judges. By giving a visual presentation, we communicated the idea better than other teams,” Dorsaneo said.

The Heritage A team won 1st place in the video contest at the 9th Annual BioEHSC™!

We also got an honorable mention in the medical category.

“The future of medical practices, or the extent of humanity’s capabilities in any field, depends on the technology we produce to address our problems,” Dorsaneo said. “The future rests on the youth to continue to revolutionize technology to propel humanity forward.”

The UC Berkeley Bioengineering Honors Society hosts the competition each spring, along with mentorship and guidance from members of the bioengineering program. After seven weeks of student preparation, candidates present their problem, proposed solution, and analysis of potential concerns to panels of professors, industry professionals, and graduate students at a final research symposium. .
