Intracranial pressure regulating system
First Claim
1. Apparatus for diagnosing, monitoring, and treating elevated fluid pressure within an anatomical structure comprising,a manifold plate, means for mounting said plate on a support so that it can be vertically adjusted whereby its height can be raised and lowered to precisely position said plate at a level chosen by the physician directly relating to anatomical structure within the patient'"'"'s body,primary and secondary stopcocks each having first, second, and third ports and mounted on said manifold plate,the first port of said secondary stopcock being connected to the first port of said primary stopcock,a calibrated manometer tube having one end connected to the second port of said secondary stopcock,a fluid collector connected to the third port of said secondary stopcock and, when in operation, normally disposed below said secondary stopcock,an automatic pressure regulator comprising an elongated tubing having first and second ends, said tubing having the first end connected to the second port of said primary stopcock, and the second end connected to said fluid collector,means for adjustably mounting a portion of said elongated tubing intermediate its first and second ends onto said manometer tube to predetermine its vertical height along the length of said manometer tube,a pressure tube having first and second ends, the first end of said pressure tube being connected to the third port of said primary stopcock,an adapter means for connecting a catheter or sub-arachnoid screw or other neurosurgical appliance to the second end of said pressure tube,whereby, in operation, said manifold plate can be mounted on a support and vertically adjusted to precisely position it at a selected position with respect to the patient'"'"'s body, and said manometer tube is vertically extending, said fluid from the patient passing into said pressure tube being maintained at a pressure no greater than that indicated by the position of the intermediate portion of said elongated tubing on sald manometer tube.

Abstract
Apparatus for monitoring and regulating intracranial pressure. Primary components are a manometer tube connected to a fluid collector, a transducer for dynamic electronic monitoring, and an automatic regulator. These components are interconnected by tubing and three main stopcocks which permit multiple procedures to be performed. A fourth stopcock, syringe and appropriate connections permit the system to be connected to a dedicated source of sterile liquid.
