Abstract
Abstract We present a simple apparatus for the intraspinal and intracisternal injection of air or other gases for the purpose of filling the cerebral ventricles and subarachnoid spaces. This apparatus has the advantage that its component parts are readily available in any laboratory and are easily assembled. It consists of two 125 cc. separatory funnels with the necessary rubber and glass connections shown in figure 1. Only one of the funnels need be graduated. A volume of 125 cc. has been found sufficient for the usual ventriculography. The entire apparatus may be sterilized by boiling and filled with sterile water or bichloride solution. Care must be taken that the connections between the lower funnel and the lumbar puncture needle are tight. The amount of pressure applied to the air under injection can be regulated by varying the distance between the two water levels in the funnels. The rate of flow of
