Mental hospitals are basically the same as general hospitals in organizational structure and subject classification, but they have special requirements for architectural design because of patients' mental disorders. The outpatient department is divided into manic department and general department. Patients in Manic Department account for about 10 ~ 15% of mental patients, and the consulting room should be slightly larger and set up separately. The general department includes patients with neurosis, and the consultation room can be the same as the general consultation room. Pediatric psychiatry should be separated from adults. The above consultation room should have a channel separate from the registration entrance. Wards are divided into quiet wards and protective wards. A quiet ward can be equipped with a large ward. The patient's condition is relatively stable and he can take care of himself in his daily life. Each room has a maximum of 10 people, and the area is larger than that of a general large ward. The protection ward is a small ward, manic, just admitted to the hospital, or used by other diseases or pregnant women. There are about 1 ~ 4 people in each room. Building treatment should be conducive to guardianship management and prevention of suicide or personal injury accidents.
The outpatient and inpatient parts of the cancer hospital are similar to those of the general hospital, but the difference is that there are special radiation medical facilities. Choose the base as far away from the city center as possible with beautiful natural environment (Figure 5). Radiological medical facilities, in addition to X-ray facilities, mainly include high-pressure treatment room, internal irradiation (intracavity) treatment room and isotope diagnosis, treatment and test. For the architectural design of these medical departments, it is necessary to properly deal with the protection of X-rays and γ-rays, as well as the pollution and harm of radioactive isotopes, so as to limit the radiation received by medical personnel and patients engaged in radiation work within the allowable dose. In the general layout, all radiotherapy rooms should be arranged centrally, which is convenient for protection management and centralized treatment of radioactive wastewater and waste. Ultra-high pressure treatment room (including accelerator, cobalt and deep X-ray therapy) should mainly solve the radiation protection problem. The radiation in the ultra-high pressure treatment room is particularly large, so it is necessary to use a circuitous maze to scatter the radiation many times and then weaken it to a safe dose. The width of the maze should ensure that the largest part of the treatment machine can pass through. After receiving intracavitary irradiation, patients should carry radioactive sources. The treatment bed must be able to automatically enter the transfer ward from the treatment room and automatically turn over and lie on the bed to avoid being directly pushed by medical staff and being injured by radiation. The transfer ward is suitable for single use. The nature of isotope ward is basically the same as that of transfer treatment ward. Because of the short range of isotope X-ray and γ-ray, we can consider setting up a double ward instead of a nurse station, but we should set up a special canteen and toilet for patients. Radiation pollution should be eliminated in the internal irradiation ward, and protective materials should be used for indoor walls and floors.
