External ventricular drainage assembly

摘要

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