SPINAL NEEDLE INCLUDING A CHAMBER FOR IDENTIFYING CEREBROSPINAL FLUID.

摘要

The invention relates to a spinal needle for analgesia and spinal and epidural anaesthesia. The needle is formed by three main elements, namely: a holding member which allows the user to hold the needle with the fingers, a chamber which receives a quantity of cerebrospinal fluid (CSF), and a cannula which is in fluid communication with the chamber and which is joined to the holding member. The chamber is preferably transparent so that the presence of CSF in the needle can be easily detected. In a preferred embodiment of the invention, the chamber includes a base which fully supports the needle. The holding member and the chamber include tactile markings with the same orientation as the tip of the cannula, indicating the direction in which the anaesthetic will be administered.
