The invention discloses a nursing device, in particular to a transfusion venting device. The invention provides the transfusion venting device capable of protecting a transfusion tube from overlapping winding. The transfusion venting device comprises a venting rod, wherein the venting rod is provided with a spiral transfusion tube placement groove. Since the venting rod is provided with the spiral transfusion tube placement groove, the transfusion tube can be wound on the venting rod according to a set spiral, the transfusion tube can be protected from overlapping winding in a venting rod sliding process, the use convenience of nurses is improved, and the transfusion tube can be prevented from being damaged. The inner wall of the transfusion tube placement groove also can be provided with a ball or a bulge, so that the transfusion tube generates slight vibration when the transfusion tube placement groove slides so as to be more favorable for discharging bubbles. The venting rod also can be operated by a grip, and the venting rod can more easily upwards move relative to the transfusion tube since the rotation, which is relative to the grip, of the venting rod is adopted.
