Abstract:
1. A device for separating platelets from a fluid suspension, comprising: a mixing chamber for containing a fluid suspension having platelets suspended therein and an aggregating agent combinable therewith to form platelet aggregates and residual fluid components; a filter configured for fluid communication with the mixing chamber and being configured to collect platelet aggregates and allow residual fluid components to pass there through; a manually operable mixing structure operable to at least partially mix components of the fluid suspension, said mixing structure comprising i) a mixing bar at least partially contained within the mixing chamber or ii) an internal geometry of the mixing chamber operable to induce mixing of the fluid suspension in response to movement thereof; a platelet aggregate collection system associated with the filter and being operable for collection, removal, and application of platelets to a wound or therapy site; and a retention member operably positioned to prevent egress from the mixing chamber during mixing, and removable or switchable to facilitate flow of platelet aggregates and residual fluid components from the mixing chamber to the filter for filtering.
