Device for isolating platelet rich plasma from tissue samples
The patent US12053779B2 describes a device designed for isolating platelet-rich plasma from liquid tissue samples. The device features a container that defines a chamber with a first and second closed end, an inlet opening for introducing the liquid tissue sample, and an outlet opening located at the first closed end. An outlet tube extends from the outlet opening towards the second closed end, and this tube is equipped with multiple hollow spindles that have withdrawal openings positioned within the chamber. These spindles facilitate the extraction of plasma by allowing fluid to flow from the outlet opening to the withdrawal openings, which are strategically spaced within the chamber. The design also includes a hub connected to the outlet tube and a vent tube extending from the chamber, enhancing the functionality of the device.
In addition to the device, the patent outlines a method for isolating platelet-rich plasma. This method involves adding a liquid tissue sample combined with a polymer composition, such as polyethylene glycol, into the container. The mixture separates into two distinct layers: the upper layer containing plasma and the lower layer comprising red blood cells. The plasma layer is then withdrawn through the outlet opening, effectively isolating the desired platelet-rich plasma. The claims emphasize the device's capacity to handle samples with a volume of less than 40 ml, making it suitable for various applications in medical and laboratory settings.
