Precise Dispensing Technology Using Electroformed Tubes for Micro-Volume Blood Diagnosis
Precise dispensing of droplets is a crucial step for acquiring reliable blood diagnostic results. When the source sample volume is limited, the need for precise dispensing of submicroliter and nanoliter quantities is especially important. In this work, we developed a positive-displacement high-precision dispensing technique using a nickel electroformed tube with an inner diameter accuracy of 5 μm or less.
A Handheld, Colorimetric Optoelectronic Dynamics Analyzer (CODA) for Measuring Total Ammonia of Biological Samples
This work introduces a wireless, solid-state, portable, and automated device capable of semi-continuously measuring the total ammonia (ammonia (NH3) and ammonium (NH4 + )) levels of fluids, including biological samples. This device reliably measures the total ammonia of biological samples (e.g., urine) faster than current ammonia quantification techniques.
Correlated Regression Feature Learning for Automated Right Ventricle Segmentation
Accurate segmentation of right ventricle (RV) from cardiac magnetic resonance (MR) images can help doctor to robustly quantify the clinical indices including ejection fraction. In this paper, we develop one regression convolutional neural network (RegressionCNN) that a holistic regression model is incorporated with convolutional neural network (CNN) to determine boundary points’ coordinates of RV directly and simultaneously.
Design of a Precision Medication Dispenser: preventing overdose by increasing accuracy and precision of dosage
Liquid medication overdose in pediatric patients results in over 70000 visits to the emergency room yearly in the USA. Various studies have demonstrated that the root cause of this high incidence is due to user and device error in dose measurement. The standard measuring cup and syringe suffer from the challenge of accurately measuring and dispensing viscous liquids, which comprise the majority of children’s medication formulations.
Reduction of Prolonged Excessive Pressure in Seated Persons with Paraplegia Using Wireless Lingual Tactile Feedback: A Randomized Controlled Trial
Pressure ulcers (PU) are known to be a high-cost disease with a risk of severe morbidity. This paper evaluates a new clinical strategy based on an innovative medical device [Tongue Display Unit (TDU)] that implements perceptive supplementation in order to reduce prolonged excessive pressure, recognized as one of the main causes of PU. A randomized, controlled, and parallel-group trial was carried out with 12 subjects with spinal cord injuries (SCI).
A Novel Cardiac Auscultation Monitoring System Based on Wireless Sensing for Healthcare
Part of the Special Issue Advanced Internet of Things in a Personalized Healthcare System: Validation, Analysis and Utilization
Heart sounds deliver vital physiological and pathological evidence about health. Wireless cardiac auscultation offers continuous cardiac monitoring of an individual without 24*7 manual healthcare care services.
