Japanese Patent JP2003515421
Kind Code:
A
Abstract:
A constant speed fluid sample collection system for use with a catheter, needle, or the like in communication with a patient's vein is useful to extract a blood sample. The system uses a constant force system to not disrupt the components of the fluid, such as platelets found in blood. The system includes a syringe device and moves a plunger at a constant velocity. The device includes a housing, a piston rod movably mounted within the housing, and a brake mechanism for controlling the movement of the piston with respect to a syringe positioned within the housing. The plunger retracts into the drive device as it is being withdrawn.
