[0006] 3. The walker is equipped with an IV stand, but the existing IV stand is not height adjustable and does not have a device for placing an IV pump or syringe pump;

[0007] 4. Some patients have abdominal drainage tubes, urinary catheters, etc. If they are fixed to their clothes and pants when they get out of bed, they are prone to falling down and affecting the patient's walking if there is a lot of drainage fluid. There is also a risk that the catheter may slip out accidentally. Existing walkers do not have a device for suspending drainage bags.

[0008] 5. Existing walkers lack safety devices, and patients may fall backward when they are too weak to get out of bed;
