SIZE: #4 1/2-#7(26G-22G) L80-150 mm;
USE: Used in subarachnoid puncture for spinal anesthesia;

1. Specially designed needlepoint shape causes no trauma of spinal dura mater, and automatically closes the puncture port after withdrawal of the needle to reduce the leak of cerebrospinal fluid, with the occurrence of PDPH evidently declined.
2. Proper shape and position of the side hole maintains adequate flow and reduces imperfect retardations as well.
