Abstract
Apparatus for sampling and measuring the pressure of spinal fluid including, a valve, a spinal needle, a manometer and a receptacle. The valve includes a housing having an elongated chamber and a hollow stem extending outwardly from the housing and communicating with the chamber, and the needle is removably connected to the stem and communicates with the stem channel and the chamber. The valve has double-ended plug means biased against both ends of the chamber in sealing engagement to prevent the escape of fluid from the chamber. The manometer is removably connected to an end of the housing and has a hollow stem to retract one end of the plug means in the chamber to establish fluid communication between the chamber and manometer. The receptacle is removably attached to an end of the housing and has a hollow stem to retract one end of the plug means in the chamber to establish fluid communication between the chamber and the inside of the receptacle.
