Stirring Cannula

Antibiotic infusions are being prescribed more frequently during the COVID-19 pandemic. My idea is to improve the process for the preparation of antibiotic infusions so more time may be spent on patient care.


Today, these infusions are often in the form of a powder that must be dissolved in solvents. I suggest the creation of a sterile bar that can be inserted into the solution in efforts to mix it safely and quickly.


I developed a mechanism in the transfer cannula that allows the sterile stirring bar to drop into the solution without coming into contact with the outside environment.


I noticed during my rotation in gerontology and vascular surgery that nursing teams frequently had difficulties dissolving the powder into the solvent. This is made even more challenging because antibiotics are not to be shaken so to avoid small air bubbles.


In alleviating and easing the process of mixing antibiotic infusions, nursing teams can spend valuable time on caring for patients instead. There are many older people who are in the COVID-19risk group, and they are particularly prone to infections, especially since they have a higher chance of having a weakened immune system. I hope my idea improves the care process by allowing more time for interpersonal care for at-risk patients during these challenging times.
