Key points of construction and operation of decoration works: 1 Material requirements for operating room 1) the material properties of the wall of the operating room shall be coordinated with the temperature and humidity of the operating room, which is not easy to crack, flame retardant, easy to clean, collision resistant, moisture-proof and mildew proof..
Therefore, the installation space needs to be planned as a whole.
The action sensitivity of RCD is far from meeting this requirement.
The construction of the new integrated clean operating room includes the operating room enclosure steel frame, the wall top plate installed on the top of the operating room enclosure steel frame, the floor installed on the bottom of the operating room enclosure steel frame and the operating room door installed on one side of the operating room enclosure steel frame; The upper part of the enclosure steel frame of the operating room is provided with a purified air conditioning unit, a shadowless lamp hanging tower base and a medical gas pipeline, the top plate of the wall is provided with a lampshade and an air supply outlet, and the lampshade is located below the shadowless lamp hanging tower base.
On the contrary, its possible misoperation can lead to power interruption and medical accidents.
For example, the normal leakage current of thoracic surgery equipment is only allowed to be 0.01ma, and the fault current in case of ground fault is only allowed to be 0.05ma.
After training, they can be applied to practice soon, quickly improve the production capacity and the success rate of one-time inspection and acceptance, and create benefits for enterprises and hospitals.
Scope of application: it is applicable to the construction of hospital clean operating room, DSA operating room, MRI operating room, ICU, CCU, NICU, central supply room and laminar flow ward.
The reason is that article 2 in 8.3.4 of technical code for building of clean operating Department of hospital (gb50333-2013): the cardiac surgery operating room must be equipped with functional grounding system of isolation transformer.

Innovatively use on-site mapping and computer three-dimensional technology to simulate the spatial layout and coordination of operating room equipment, facilities, wind, water, electricity, gas structural accessories, building structure and decorative hexahedron, so as to ensure the safe working distance, operation and maintenance space of equipment and facilities, and ensure the one-time success rate of installation work.
According to the professional safety spacing, operation and maintenance spacing required by the specification, use the computer three-dimensional technology to simulate the location of equipment and facilities and the direction, plane turning and facade turning of the professional pipelines of air, water, electricity and gas.
Because the capacitive reactance is very large and the capacitive current is very small, there is no danger of electric shock.
When the first grounding fault occurs in the system, the fault current does not directly return to the power supply, but can only return to the power supply through the capacitance of the other two non fault phase conductors to the ground.

Instead of adopting the inappropriate practice of “equipotential grounding”, many professional suppliers in the operating room have technical blind spots here, which is a fuzzy concept that should be clarified in the design and installation of the operating room.
It can not only prevent personal electric shock, electrical fire and explosion, but also make all kinds of electrical systems and medical systems operate normally and play their due role.

According to the plane setting out drawing of the operating room, snap the vertical and horizontal reference lines of the operating room on the ground, following the operating room first, then the auxiliary room and corridor.
The integrated clean operating room of the utility model has the advantages of simple structure and short construction time, greatly improves the construction efficiency and saves time, and the operating room has stable performance, is not prone to failure and saves the maintenance cost.
Scientificity: the construction method is the sublimation and improvement of rich practical experience in the construction of operating room.
RCD is not allowed to be installed in surgical equipment circuits, ICU, CCU and other medical equipment circuits that maintain the patient’s life.
The main characteristics of the method are scientific, advanced, innovative and practical.
1) The equipotential bonding in the operating room connects the metal structural parts, pipes, cable sheath and PE line connected to the electrical equipment shell in the operating room according to IEC standards, and other measures are supplemented as needed to form a quasi equipotential Faraday cage similar to the aircraft fuselage.

The general practice of professional suppliers of ordinary operating rooms is to use it power supply only in class I operating rooms and RCD protection in the power supply circuits of other operating rooms and clean auxiliary rooms.
Only alarm without cutting off the power supply can maintain the uninterrupted power supply and ensure the continuous power supply of important equipment during operation.
It is not necessary to cut off the power supply in case of the first grounding fault, because the it power supply terminal is not grounded by system or through high impedance.
Because the clean operating room has the characteristics of large air volume of air conditioning system, low temperature difference and centralized layout of operating equipment, the space resources in the ceiling and partition wall of the operating room are precious.
advanced: operation room equipotential bonding and IT power supply are the advanced measures to ensure the safety and reliability of the medical system operation.
This practice is unscientific, and there are defects in the specification.
Map the space map in the ceiling and partition wall of the operating room.
The construction method process meets the requirements of technical code for building of hospital clean operating department (gb50333-2013): the construction of clean operating room should pay attention to the two key links of air purification and the safety and reliability of medical system operation.
Construction process flow and operation points: construction process flow: overall construction process of integrated clean operating room construction operation points: on-site mapping, three-dimensional simulation and setting out: 1 The elevation datum line + 1.0m shall be measured on the concrete structure wall column in the installation area of the operating room.
2) The operating room adopts it power supply and it system.
After eliminating the spatial interference with each other, determine the comprehensive layout of professional equipment and pipelines, Guide post-processing, production and installation to improve the success rate of one-time installation.

Cut off the power supply only when the second grounding fault turns into phase to phase short circuit.
The tools and technologies used in the practical construction method process are easy to master in engineering design and construction.

The potential of the Faraday cage is used as the reference potential, and the equipotential bonding is used to replace the earth, To achieve electrical safety and anti-interference level close to aircraft electrical devices.
Setting out shall follow the principle of room outline first and then details.
The allowable deviation of setting out is that the length and width error of the operating room is controlled within 2mm and the diagonal error is controlled within 4mm.
