摘要： A cannula insertion device is disclosed. The device includes a needle carriage, a rail device on which the needle carriage is slidable, a yoke having a channel, a linkage connected to the needle carriage and extending into the channel, a torsion spring with one end connected to the linkage, and locking device for locking the torsion spring in tension and maintaining the needle carriage and the linkage in a locked position prior to activation. Upon release of the locking device, the tension of the torsion spring is released, which causes the linkage to move in the channel and slide the needle carriage along the rail device. A catheter carriage may also be provided for actuation by the linkage.
