Needle-free Anemia Test

Needle-free Anemia Test A recent TEDTalk tells a tale of perseverance and engineering know-how that resulted in a low-cost, non-invasive device for anemia diagnosis. Witness to preventable anemia-related death in his native India, one engineer enlisted the expertise of colleagues to devise a simple diagnostic for point-of-care application. The monitor had to be portable for usability by community health workers and to function without needle pricks to assure patient compliance. After 32 attempts, the battery-operated ToucHB for hemoglobin, oxygen saturation, and heart rate measurement was designed, operating on the optical principle of photoplethysmography.

Spiders Inspire Biomedical BOAS

Spiders Inspire Biomedical BOAS The beads-on-a-string (BOAS) structure used by orb-weaving spiders to build webs inspired University of Akron, OH, engineers to fabricate similar microthreads for medical use. Glue coats the biocompatible material, forming beads which provide adhesive properties and an agent for embedding medication. Video explains how the synthetic silk fills a need identified at a wound clinic.

Kinematic System Produces New Valves

Kinematic System Produces New Valves Defective venous valves can now be replaced with a polycarbonate-urethane implant designed in Germany. The prosthesis was developed in concert with an automated production scheme featuring a 3D droplet dispensing tool. Polymer is deposited one droplet at a time onto implant molds to achieve very thin layers with exacting precision.

3D Circuitry and Two-shot Molding

3D Circuitry and Two-shot Molding Meet electronic device design miniaturization and flexibility challenges with technology that combines Molded Interconnect Device/Laser Direct Structuring antenna capabilities. Medical Product Manufacturing News reports that both two-shot molding and a 3-axis laser are used to produce integrated fine-pitch 3D circuitry with shielding in a single molded device for high-density medical devices.

Micropower for Cardiac Monitor

Micropower for Cardiac Monitor Opportunity for designing low power heart rate monitors lies in micropower integrated circuit (IC) components. By operating on low voltage and current, these ICs conserve battery power. Some design guidelines offered cover circuitry of heart rate monitor front ends, including signal processing in the microconverter, lead off detection, and passive-component sizing.

Fast Track for Radiation-free Scanner

Fast Track for Radiation-free Scanner Non-load bearing components for a prototype imager that scans a radiation-free tracer injected into the bloodstream are being assembled with 3D printer technology. University of California (Berkeley) researchers cite cost and time savings with this approach. Detection of iron oxide nanoparticles by X-space Magnetic Particle Imaging currently enables real-time angiography of small animals.

Electron Ptychography Loses the Lens

Electron Ptychography Loses the Lens Computers replace lenses in the electron microscopy technique advanced at University of Sheffield, UK. Higher resolution images are realized without the limits imposed by electron lenses and without the need to stain cells. Electron ptychography generates images by reconstructing scattered electron waves after they pass through a sample.

oPAD: Cheap Sensor Joins the Fold

oPAD: Cheap Sensor Joins the Fold Similar to a paper-based pregnancy test and suggestive of origami, a 3D microfluidic sensor costing pennies can test for malaria and HIV. Hydrophobic material applied to folded chromatography paper guides introduced blood or saliva to embedded test reagents, which will change color or fluoresce. The origami Paper Analytical Device (oPAD) is an innovation from the University of Texas (Austin).

Learning to Inhale

Learning to Inhale Statistics show that most asthma sufferers in the U.S. and UK do not use their inhalers effectively, leading to avoidable hospital admissions. Cambridge Consultants seeks to change this trend with a training device demonstrated in trials to more than double correct inhaler use rates. Medgadget hosts a video showing the merits of the interactive wireless training system.
