A device for withdrawing or injecting a fluid

摘要

A device for withdrawing or injecting a fluid has a handle adapted to facilitate grasping thereof, and an elongate penetrating element coupled to the handle and having a proximal inlet port and a distal piercing tip for penetrating into tissue and bone. The device is particularly effective in that the configuration of the handle and the elongate penetrating element allows a person to grasp and manipulate the handle while accessing the inlet port to aspirate fluid through it. The device is also effective to facilitate penetrating of the device into bone due to the configuration of the distal penetrating tip. The device is particularly suitable for use as a bone marrow aspiration device.
