Portable Resource-Independent Blood-Plasma Separator

Area of Science:

• Biomedical Engineering
• Medical Devices
• Hematology

Background:

• Centrifuges are standard for lab blood processing but impractical for field use due to power, size, and complexity.
• Limited field-deployable solutions hinder remote blood sample collection in human and veterinary medicine.
• A resource-independent method for efficient blood-plasma separation is needed for mobile practitioners.

Purpose of the Study:

• To develop a portable, resource-independent device for efficient blood-plasma separation.
• To introduce the High Efficiency Rapid Magnetic Erythrocyte Separator (H.E.R.M.E.S) sleeve for field sample processing.
• To demonstrate the efficacy of magnetic bead-based separation in a novel sleeve format.

Main Methods:

• Development of the H.E.R.M.E.S sleeve utilizing a magnetic bead-based separation assay.
• Employing a unique mixing scheme for efficient erythrocyte separation from plasma.
• Testing the sleeve with human blood samples up to 1 mL volume.

Main Results:

• The H.E.R.M.E.S sleeve achieved highly efficient erythrocyte-plasma separation.
• The device demonstrated ease of use and complete resource independence.
• Performance was validated against conventional end-over-end mixing techniques.

Conclusions:

• The H.E.R.M.E.S sleeve presents a viable, resource-independent alternative to centrifuges for field blood sample processing.
• This technology can significantly improve remote blood collection capabilities for mobile medical practitioners.
• The magnetic bead-based approach offers a scalable solution for efficient plasma separation in diverse settings.
