We illustrate SLA 3d-printing printing methods to produce COVID-19 nasopharyngeal testing swabs, proving that they can be produced in a manner that is safe and clean for the users. 3D printing is an effective and efficient tool that can be used for a wide variety of applications, especially for a quick turn around in response to a shortage, and specifically for this application, this method was created in response to the swab shortage in early summer 2020.
Medical device companies that aim to sell catheters with pressure sensing elements need a way to test their systems during the design phase. An example of one of these products is an Intra-aortic Balloon Pump (IABP) which provides mechanical pumping assistance to a patient experiencing cardiogenic shock.
To test these devices, companies will place the assembly in controlled pressure chamber to examine the response to pressure changes. However, commercially available systems are cost prohibitive.
To solve this problem, a custom, low-cost, pneumatic catheter test chamber was designed and built to provide a benchtop platform for experimentation.
In order to control the chamber pressure, the electromechanical system utilizes feedback control and solenoid valves controlled by an Arduino microcontroller. Since pneumatic systems exhibit nonlinear behavior, a novel control method was used to implement proportional-integral control and simulate the pressure profile experienced in the human body.
Extended reality tools have been theorized to revolutionize medicine. Many tools on the market today fail to provide value in a clinical setting. Extended reality tools must emulate existing clinical workflows to add value to a doctor’s process. A framework is created to capture the clinical workflow by defining user tasks, graphical user interface functionalities and backend software functionalities. Two extended reality tool designs are presented based on the workflow captured in the framework. The first extended reality tool is designed for communication and collaboration, while the second tool is designed with a full immersive experience.
Outcomes for cardiac arrest (CA) are currently poor, even when CA is experienced in hospital. While the gold standard for treatment is extracorporeal membrane oxygenation (ECMO), cardiopulmonary resuscitation (CPR) is most often used to treat cardiac arrest. We propose a fundamental change in ECMO technology to increase access by reducing the amount of highly trained personnel required to perform this treatment. Additionally, we propose a design in which ECMO functionality is combined with functionality of an intra-aortic balloon pump (IABP) in order to further reduce cardiac workload in cases of cardiac arrest and cardiogenic shock.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
