Where can I buy a medical nursing bed in Beijing? Is the price of a medical nursing bed cheap?

I bought a nursing bed in a medical device company of Konka era in Beijing, and I felt that the nursing bed they sold at home was quite affordable and the service attitude was quite good. They have many nursing beds, some like those in hospitals, some are made of wood, and some can be turned over to sit. What we bought were wood, foot pads, guardrails and infusion racks, and their waiters were very enthusiastic and professional.
