Peristaltic pump for fluid handling in bioanalytical applications
The patent US12011716B2 describes a peristaltic pump designed for precise fluid transport, featuring a unique cartridge structure. The cartridge includes a base layer with channels that have a triangular cross-section, allowing for effective fluid movement. The channels are complemented by a surface layer made of elastomer, which seals the channel openings. The pump operates through a roller mechanism connected to a crank-and-rocker system, which is further linked to a roller arm and a hinge equipped with a spring. This design enables the pump to transport fluids with varying resolutions, specifically targeting flow rates of 1 to 1000 microliters per pump cycle.
Additionally, the patent outlines the versatility of the peristaltic pump, indicating its suitability for sample preparation in various applications, including analysis, sequencing, and identification of biological materials such as nucleic acids, peptides, proteins, tissues, blood, and secretions. The pump's design allows for the use of interchangeable cartridges, enhancing its functionality. The roller's interaction with the cartridge occurs at a non-wetted portion, ensuring minimal contamination. The pump is also engineered to achieve specific stroke lengths, ranging from 10 mm to 20 mm, further optimizing its performance for precise fluid handling in laboratory settings.
