  • Patent number: 11083841
    Abstract: Needle protector assemblies including needle assemblies and needle protectors for housing used blood collection needles are disclosed. The needle protectors are single-piece protectors that include an open distal end for receiving a needle hub (with a needle mounted thereon). A retaining member locks the needle hub when the needle hub is substantially retracted. A stop engages the needle hub in a fully retracted position such that a needle post is completely contained within an interior chamber of the needle protectors. A viewing slot in the needle protectors is provided.

  • Patent number: 8999161
    Abstract: A plasma filter is provided for separating aggregates and targeted blood cell species from plasma comprising a filter housing with an inlet and an outlet and an internal flow path between the inlet and outlet. A filter media is disposed in the flowpath between the inlet and the outlet for filtering plasma that passes therethrough. The filter media comprises a filter configured to substantially remove targeted blood cell types from the plasma and a prefilter upstream of the filter, the prefilter having at least one reinforcement layer.
