Abstract:
A sampling apparatus is disclosed that includes a sample container and a sample device receiver in communication with tubing connected to the container. The receiver being adapted to receive a sampling device for withdrawing a fluid sample from the tubing and may be directly attached to a connector located between segments of the tubing.
Abstract:
A method for controlling the flow of liquid through a flexible tube in a blood collection set is provided. The set includes a venipuncture needle (12), a tube (14) for receiving blood and which provides branches to a blood collection container (18) and to a sampling pouch (20), a first flow control clamp (22) and an irreversibly closable flow control clamp (30) on the two branches. The method allows blood to flow from the tube (14) to the sampling pouch (20), irreversibly closing the flow control clamp (30) on the branch to the sampling pouch (20) whereby that flow-path is irreversibly closed and thereafter allowing blood to flow from the tube (14) to the collection (18) container via the other branch. The irreversibly closable flow control clamp (30) includes a flexible body (34) apertures (40, 44) and having two legs (36, 38) moveable between a spaced apart and a closed position, a tube contacting member (48) for clamping a tube passing through the apertures when the legs are in the closed position.
Abstract:
Methods and apparatus for collecting blood samples in vacuum sample tubes are disclosed. The samples, including the initial blood sample, are substantially free of excess air. Disclosed is also a biological fluid sampling system (18) comprising: a plastic container (42) including an interior chamber (54); a sample access site (68) external to and spaced from said container by y preselected distance; an internal flow path (43) communicating with said access site and extending substantially into said interior chamber, said internal flow path providing the only path for blood flow into and from said chamber.
Abstract:
A holder (68) for receiving a sampling tube (70) of a blood sampling system is disclosed. The holder (68) has an interior pocket (81) which can be conformed from a closed position to an open position for receiving the sampling tube (70).
Abstract:
Systems and methods treat plasma by separating targeted blood cell species such as red blood cells and platelets from the plasma by filtration through hydrophilic polyvinylidene fluoride (PVDF) membranes.
Abstract:
Needle protectors (40) for housing used blood collection needles are disclosed. The needle protectors are single-piece protectors that include an open distal end (44) for receiving a needle hub (20) (with needle mounted thereon). A retaining member (60) locks the hub when the needle hub is fully retracted. A viewing slot (62) in one of the walls of the needle protector is provided.
Abstract:
Systems and methods collect leukocyte reduced blood components, including plasma that is free or virtually free of cellular blood species, such as red blood cells, platelets, and leukocytes.
Abstract:
Needle protectors for retaining needles (12) are disclosed. The needle protector (40) includes a housing (42) with an opening (50, 48) at each of a proximal (46) and distal end (44). The needle protector (40) may include a portion that is depressable to a substantially fixed position over the needle (12) retracted within the housing (42).
Abstract:
This invention is a container (46) for housing body fluids. The container comprises a body defined by flexible walls having an interior for housing the body fluid. An elongated tube (44) extends from the body for housing a fluid to be added to the body fluid. The tube includes means (18, 32) (see Fig.1) for allowing selective fluid flow from the interior of the tube to the interior of the body allowing the fluid to be added to the body fluid. Additionally, the means for allowing selective fluid flow allows the body fluid to be expressed from the body of the container into the elongated tube. The present invention also provides a method for storing and treating blood.
Abstract:
A steam sterilizable unit for inactivating pathogens in a body fluid is provided including a plastic structure for housing a therapeutically effective amount of a methylene blue solution. The plastic structure preferably includes at least an inner layer constructed from a non-PVC plastic. Preferably, the methylene blue solution has a pH of less than 7.0 and preferably less than or equal to approximately 6.3.
