Auto Adjustable Flow Regulator, Ethan Hemmerlin, Jack Dooley
Auto Adjustable Flow Regulator, Ethan Hemmerlin, Jack Dooley
Biomedical Engineering
The Auto-Adjustable Oxygen Flowmeter device is to be used in conjunction with an oxygen source or reservoir, as well as a low-flow nasal cannula apparatus. The device is applicable for patients requiring an oxygen flow rate of 0-6 L/min. Further, the device works to maintain a healthy blood-oxygen concentration of 90-94% for typical patients, as well as an 88-92% range for COPD patients who are chronic CO2 retainers. A reflective pulse oximeter will record the SpO2 concentration of the patient. The outputted SpO2 concentration will be transmitted to an internal processing PCB from which it will interact with the oxygen …

Insole Fall Prevention Device, Nick M. Hughes, Andrew M. Slaboda
Biomedical Engineering
Falls among the aging population occur every single day, with 1 in every 5 resulting in some injury and 300,000 hospitalized every year with a hip fracture [1]. The most popular and effective way to mitigate these falls is through physical therapist intervention. However, with the increased popularity in telerehab, many patients at risk for falls cannot accurately convey their gait tendencies to their physical therapists from the comfort of their home or while not in direct contact with the PT. A device like an insole, implanted with force sensors, which measures different parts of a patient’s foot, could convey …
Smart Motor Syringe System, Conard Chan, Jenny Chiao
Smart Motor Syringe System, Conard Chan, Jenny Chiao
Electrical Engineering
Syringe pumps are widely used in many research applications especially in the applications that need precise control. Today most medical research utilizes syringes to control the fluid being pumped to the experiment objects. In most cases microscopic or nano-scopic motion control is required to acquire optimal results, such application includes purification of DNA/RNA from contaminants[1]. The high precision required to control the syringe pump makes it difficult to perform manually. This paper focuses on the design of an intelligent syringe pump motor control system to achieve reliable and precise control for biomedical experiments. This project improves medical research quality with …
On-Demand Label Production, Robert A. Zimmerman
On-Demand Label Production, Robert A. Zimmerman
Master's Theses
The production and approval process for the various labels used in clinical trials wastes significant time and resources through the need to outsource label production or rely on large reams of pre-cut label stock for each revision throughout the process. An in-house, on-demand label printing and cutting system is a potential remedy to this waste. Previous work by Cheadle et al. resulted in a functional electomechanical prototype of the label cutting aspect of this research, capable of rudimentary linear cuts. In this continued research, emphasis was placed on improved label cutting capabilities and creating PC control software for label design. …

Hands-Free Ultrasound Transducer Attachment, Christina Harrison, Glenn Farina, Harshveer Dhaliwal
Biomedical Engineering
This document describes a background on current ultrasound technologies and the troubles that have inspired the need for a hands-free ultrasound transducer device, as well as the regulatory requirements, like patents and standard codes, for the intended invention. It also explains the Stage Gate Review process used to project plan the design of the device, a description of the final design and how it was developed, and the IQ/OQ/PQ. The objectives necessary to design this device, in order to meet all the requirements of the sponsor, are also summarized here. The design process including manufacturing instructions, prototype evolution, and the …
