Abstract: Apparatus for removing fluid from the body of a patient, such as in paracentesis and thoracentesis. Fluid may be withdrawn via a retractable needle assembly, including a sharp introducing needle and a retractile blunt needle. The needle assembly is housed in a housing having a chamber with two oriented grommets that prevent fluid flow through the chamber (other than through the needle assembly) both when the needle assembly is inserted through the chamber and when it is withdrawn. A beam spring blocks the chamber after the needle assembly is withdrawn so that the device cannot be reused.

Abstract: An apparatus for managing and controlling fluid flow through a plurality of fluid conduits includes a chassis, a plurality of conduit occluders mounted in the chassis, each occluder for association with at least one of the plurality of fluid conduits and each being selectively actuatable between an open position permitting fluid flow through a respective fluid conduit and a closed position obstructing conduit fluid flow. A single actuator is mounted in the chassis, the actuator for adjusting the plurality of occluders between the open and closed positions. A roller cage is also mounted in the chassis for mechanically interconnecting the actuator to the plurality of conduit occluders so that the single actuator is mechanically capable of maintaining one of the plurality occluders in the closed position while maintaining another of the plurality of occluders in the open position.

Abstract: A method and apparatus for removing fluid from the body of a patient, such as in paracentesis and thoracentesis, is provided. Fluid may be withdrawn via a needle assembly including a sharp introducing needle and a retractile blunt needle. The needle assembly may be withdrawn after the introduction of a drainage catheter, and a valve with multiple sealing points prevents body fluids from leaking from the device through the needle space and prevents communication between the atmosphere and the patient through the needle space. A second drainage port may be used after the needle is withdrawn.
