External ventricular drainage assembly.

摘要

An external ventricular drainage assembly (10) includes a ventricular drainage catheter (14) which can be placed in the ventricles of a patient's brain and which is connected to a suture tab (18) for securing the catheter to the patient and for preventing relative movement between the catheter and patient. A valve (22) is connected to the catheter for selectively opening and closing the external ventricular drainage assembly to fluid flow. An adapter (30) is connected to the valve for providing access to the fluid flow path within the assembly. A one-way valve (34) is connected to the adapter. A first length of flexible tubing (36) is connected to the one-way valve and is joined through a connector (40) to a second length of flexible tubing (42). A collection reservoir (46) is connected to the second length of flexible tubing and includes an entry (50) and outlet port (52). A drip chamber (48) is positioned between the second length of flexible tubing and the collection reservoir.
