SPLIT PISTON METERING PUMP - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240024568 titled 'SPLIT PISTON METERING PUMP

Simplified Explanation

The abstract of the patent application describes a micropump that utilizes axially oriented pistons to create a pump volume. By moving the pistons axially within a pump housing, a specific amount of fluid is drawn from a reservoir port into the pump volume. This fluid is then delivered to a cannula port when the space is collapsed. The pistons have radially situated seals that work together with the axial movement to open and close the cannula port and the reservoir port at different positions of the piston stroke.

  • The micropump uses axially oriented pistons to define a pump volume.
  • Translating the pistons axially with respect to each other draws a metered amount of fluid into the pump volume from a reservoir port.
  • The fluid is delivered to a cannula port when the space is collapsed.
  • Radially situated seals on the pistons close off and open the cannula port and the reservoir port at different positions of the piston stroke.

Potential Applications:

  • Medical devices requiring precise fluid delivery, such as insulin pumps or drug infusion systems.
  • Laboratory equipment for controlled fluid handling and analysis.
  • Microfluidic systems for research and development purposes.

Problems Solved by this Technology:

  • Accurate and controlled delivery of fluids in small volumes.
  • Elimination of leakage and backflow in microfluidic systems.
  • Efficient and reliable fluid handling in medical devices.

Benefits of this Technology:

  • Precise and controlled fluid delivery.
  • Compact and portable design suitable for miniaturized devices.
  • Reduced risk of contamination and infection due to sealed system.
  • Improved efficiency and accuracy in fluid handling processes.


Original Abstract Submitted

a micropump according to the invention uses axially oriented pistons to define a pump volume. translating the pistons axially with respect to each other within a pump housing draws a metered amount of fluid into the pump volume from a reservoir port for delivery to a cannula port when the space is collapsed. radially situated seals on the pistons cooperate with the axial movement to close off and open the cannula port and the reservoir port respectively at different positions of the piston stroke.
