The present invention relates to the technical field of medical devices, and specifically to a fixing device suitable for ECMO treatment pipelines, including a pair of
blood vessel binding groups attached to the
thigh, a
blood vessel fixing group fixed to the bedside and used to support the
blood vessel binding group, and a return blood vessel fixing group arranged on the
head and neck. By adjusting the position of the card frame on the positioning tube, the tube binding pad, the splint and the positioning tube form an effect of clamping the
thigh; then the blood vessel fixing group is fixed to the bedside
bed bar, and the tube binding pad is limited by the pad support rod; when the
thigh needs to move, just unplug the pressure rod to lift the leg; by pressing the
chin pad against the
chin, wearing the headband on the top of the head, and then positioning the
jugular vein return blood vessel on the side of the neck on the tube sleeve, the
jugular vein return blood vessel and the neck clamp form an integral state, which will be synchronized with the deflection of the neck to avoid loosening of the connecting
pipe.
