  • Patent number: 7618407
    Abstract: The invention includes a bag system for collecting a biological fluid, in particular blood. The system includes a device for collecting the fluid which is in fluid communication with at least one fluid collection bag, and a device for sampling the fluid to be collected which includes at least one sampling receptacle. The sampling device includes a device for transferring the fluid from the bag system into the sampling receptacle or receptacles, in which the transfer device is provided with a device for associating the receptacle or receptacles. The transfer device may be arranged to allow the support of the receptacle or receptacles in a standby position, the guidance of the receptacle or receptacles to a transfer position and, after transfer, the dissociation of the receptacle or receptacles from the bag system.

  • Patent number: 5832948
    Abstract: The liquid transfer system includes a liquid supply tank and at least two pressurizable liquid holding vessels. The liquid holding vessels are placed beneath the supply tank, and a liquid supply line connects the supply tank to each vessel. The liquid supply line is operated as a siphon from the tank to each vessel, in order to move liquid from the tank to each vessel. Each vessel is alternately filled and pressurized to dispense liquid from the vessel, such that one vessel is being filled while the other is dispensing liquid, and a constant controllable liquid output flow is achieved. A preferred embodiment includes a liquid recycling line to recycle or constantly move the liquid within the system to achieve thorough mixing, and an in-line filter to improve liquid purity.
