This invention provides a bed sheet changing device for bone marrow aspiration patients, comprising a bed frame, a drive mechanism, and a lifting mechanism. The bed frame has an internal cavity, and a strip-shaped groove is formed at the top of the bed frame. A support belt is positioned at the top of the strip-shaped groove, and rods are positioned on both sides of the support belt. The two rods can respectively roll up both sides of the support belt to the underside of the support belt. Moving blocks are slidably installed on both sides of the support belt within the cavity. Each of the two moving blocks has a bearing plate on its top, and the two bearing plates are connected to their adjacent rods through connecting parts. The drive mechanism is used to drive the two moving blocks to move closer to or away from each other. The lifting mechanism is used to lift the support belt above the bed frame. This invention utilizes the drive mechanism in combination with the lifting mechanism to simultaneously raise or lower the support belt when unfolding or retracting it. This facilitates quick bed sheet changing for medical staff, eliminating the need for the patient to get out of bed, effectively reducing patient discomfort and the workload of medical staff.
