With the development of the times, the progress of society, the development of modern medicine and the construction of hospital clean engineering requirements have become higher and higher. In addition to the design and decoration of functional subjects such as operating rooms, various experimental inspection rooms, clean rooms, and sterile rooms, the hospital purification project includes the configuration of professional laboratory furniture such as air showers, transfer windows, and ultra-clean workbenches, as well as air purification technology. , Air-conditioning technology, water purification technology, gas purification technology and other clean technologies. It is a highly systematic project. CEIDI has accumulated a wealth of experience in the process of cooperating with medical institutions for many years. This article takes the clean operating room purification design of a hospital as an example to summarize and summarize the key points of popular science purification engineering decoration and key air-conditioning design points.The key points of clean operating room decoration

1. Operating room wall

(1) The walls of the operating room and the clean corridor are made of anti-rust, scrubbing, acid and alkali, fireproof, sound insulation and heat preservation metal materials (electrolytic metal plate or color steel plate) to make anti-bacterial walls, and the wall connection adopts circular arcs. form.

(2) Color steel plates are used in the clean exterior corridors and other auxiliary rooms, and the thickness of the color steel plates must be implemented in accordance with national standards.

2. Operating room floor

(1) All use anti-static, anti-bacterial, fire-resistant, and wear-resistant pvc coils.

(2) The joints of the coiled materials are all welded by heat welding, smooth and seamless, and are connected with the wall in a circular arc.

3. Ceiling

(1) The ceiling height of the operating room is designed to reach 2800mm, and the material of the operating room (except the debridement room) is the same as the wall.

(2) The design ceiling height of corridors and auxiliary rooms is up to 2800mm, and color steel plate ceilings are adopted.

4. Door

(1) The entrance door of the operation department, the door of the operating room, and the door of the replacement room are all designed with a light-controlled induction electric door. All other doors in the operation department are designed with an electric door.

(2) All door covers are made of stainless steel.

(3) The doors of related auxiliary rooms are manual doors.

(4) The corridor is equipped with anti-collision handrails.

Electrical design requirements for clean operating rooms

1. The power distribution load of each operating room should be no less than 8KVA.

2. The lighting of the operating room is composed of a clean air-sealed lighting lamp panel, which is forbidden to replace ordinary lamp panels, and the lighting is controlled by multiple points.

3. The designed average illuminance of the surgical department should be above 400Lex.

4. The average illuminance of auxiliary rooms and corridors should be above 200Lex.

Design requirements for clean air conditioning in clean operating rooms

1. The clean air-conditioning system should keep the clean operating department under control. It should not only ensure the overall control of the clean operating department but also enable flexible use of the clean operating rooms. The clean operating room should be separated from the auxiliary rooms with a clean air-conditioning system. Design parameters It meets the requirements of the "Standards for the Construction of Hospital Clean Surgery Department".

2. Air distribution

(1) The air supply outlets in the clean operating room should be centrally arranged above the operating table, so that the operating table and surrounding areas are located in the mainstream area formed by clean airflow.

(2) The clean operating room uses aluminum alloy spray ceiling air supply device to supply air, and the size of the air supply device should not be less than one hundred grade 2.4*2.6 and ten thousand grade 1.4*2.6 respectively.

(3) The clean operating room should adopt bilateral lower return air, the height of the upper side of the return air opening should not exceed 0.5 meters above and below the ground, and the lower side of the hole should not be less than 0.1 meters above the ground.

(4) The clean corridor of the aseptic auxiliary room is the upper air supply and the lower return air, and the efficient air supply outlet provides air.

(5) Clean corridors use high-efficiency air supply outlets to supply air, and upper return air.

3. Purification air conditioning unit configuration requirements

(1) The operating room, clean corridors and auxiliary rooms are assembled with imported parts to assemble medical sanitary air-conditioning units with humidifiers and dry steam devices.

(2) One-to-three operating room for 10,000-level operating room

(3) The fresh air system adopts zoned centralized control, and a group of fresh air units is set up.

4. Purification air-conditioning system components and materials

(1) The inner surface and built-in parts of the purification air-conditioning unit should be made of materials resistant to corrosion by disinfectants, and the surface of the material should be smooth and clean.

(2) The internal structure should be easy to clean, and the cleaning wastewater can be discharged smoothly, and it is not easy to form dust and breed bacteria.

(3) The condensate outlet of the surface cooler should have an automatic anti-back suction device and a device that can smoothly discharge the condensate under negative pressure. The condensate pipe cannot be directly connected to the sewer pipe.

(4) Differential pressure gauges should be installed before and after all levels of air filters in the unit, and the measuring connection should be unobstructed and tightly installed.

(5) The materials of the muffler-type muffler components should be corrosion-resistant, non-moisture-absorbing, dust-free, and non-dust-generating, and the fillers are not allowed to use glass fiber and its products.

(6) All levels of filters in the purifying air conditioner should be of primary type, and the final filter should be made of materials that do not absorb moisture and do not grow bacteria. Wooden frame products are not allowed, and the finished product should not have irritating smell.

5. Purification system configuration requirements

(1) Purify the fresh air of the air-conditioning system. The air supply is mandatory and should be controlled by a constant air volume valve.

(2) The purification system is composed of air conditioning unit, constant air volume valve, stainless steel ceiling air supply device, high efficiency filter, muffler, sterilization device, fire damper, galvanized steel duct (including heat preservation), etc.

(3) Each purification system in the operating room is equipped with an electric heating device for the air duct.

6. Design requirements for purifying air-conditioning automatic control system

(1) Each purification system must be equipped with automatic control equipment.

(2) The temperature and humidity sensor is used, and the actuator is matched with the controller to realize constant temperature and humidity control.

(3) The operating room is provided with remote control and temperature and humidity setting devices for the unit.

(4) It should be able to implement process control of the blower, fresh air blower, exhaust fan, surface cooler, filter, fire damper, regulating valve and other equipment in the system.

(5) The automatic control system should include two parts: electric control and weak current control.
