In the hospital, we can often see all kinds of symbols, which are usually used to indicate the direction, explain the purpose of the ward or department, and remind patients or medical staff to pay attention to matters. For example, a green cross represents a medical institution, a red +U sign represents an emergency, and a blue "P" sign is a hospital parking lot. These signs have played a very important role in the hospital, effectively improving the management level and medical service efficiency of the hospital.

There are many symbols in the hospital, besides those mentioned just now, there are many more. For example, the red letter "H" stands for operating room, the yellow letter "ICU" stands for intensive care unit, and the purple letter "D" stands for pharmacy. The function of these signs is to separate the services and facilities of the hospital, provide convenience and guidance for patients and medical staff, and make us more convenient to understand the internal structure and service purpose of the hospital.

The symbols in the hospital help us to identify and use medical facilities, but we also need to pay attention to some usage details. For example, patients should pay attention to the meanings of different symbols in the hospital and go to the corresponding departments or wards correctly to avoid getting lost or other problems. At the same time, medical staff also need to provide correct medical services according to the meaning of various signs to ensure the safety and health of patients. In daily use, we also need to pay attention to the maintenance and update of these symbols to ensure the normal use and effective play of hospital symbols.
