Paperfuge: An ultra-low cost, hand-powered centrifuge inspired by the mechanics of a whirligig toy

Sample preparation, including separation of plasma from whole blood or isolation of parasites, is an unmet challenge in many point of care (POC) diagnostics and requires centrifugation as the first key step. From the context of global health applications, commercial centrifuges are expensive, bulky and electricity-powered, leading to a critical bottle-neck in the development of decentralized, e...

A Hand-Powered, Portable, Low-Cost Centrifuge for Diagnosing Anemia in Low-Resource Settings

This report describes the development of a hand-powered centrifuge to determine hematocrit values in low-resource settings. A hand-powered centrifuge was constructed by using a salad spinner. Hematocrit values were measured by using the hand-powered device, and results were compared with those of a benchtop centrifuge. The packed cell volume (PCV) measured with the hand-powered device correlate...

A wrist-powered hand prosthesis.

This paper describes a prosthesis for patients who have had a partial amputation of the hand, or who have congenital absence of all or part of the hand. The prosthesis incorporates a new concept whereby the grip is operated by flexion and extension of the wrist. A covering for the prosthesis has been developed using a silicone polymer which produces a lifelike flexible glove. Thirteen patients ...

Computational Fluid Dynamics Ventilation Study for the Human Powered Centrifuge at the International Space Station

The Human Powered Centrifuge (HPC) is a facility that is planned to be installed on board the International Space Station (ISS) to enable crew exercises under the artificial gravity conditions. The HPC equipment includes a “bicycle” for long-term exercises of a crewmember that provides power for rotation of HPC at a speed of 30 rpm. The crewmember exercising vigorously on the centrifuge generat...

Individualizing goals for users of externally powered partial hand prostheses.

Based on recent advances in prosthetic technology available for individuals with partial hand loss or deficiency, research is needed to best ensure the acceptance of these devices. Additionally, this population is subjected to higher risks of overuse syndromes. With improved technological advances in prosthetic devices, clients can engage in more complex activities with less compensation. The p...
