Three overlapping lead doors , designed for composite operating rooms, typically refer to a combination of three doors used to meet the highest levels of air cleanliness, radiation protection, and operational isolation requirements. This design is commonly used in advanced composite operating rooms for hybrid surgeries, such as combining open surgery with interventional therapy.
Parameter | Details |
Structural Characteristics | The door body consists of three independent door panels (usually left, middle, and right), which are opened by overlapping sliding and sliding |
Protection equivalent | 3mmPb , 5mmPb , 8mmPb , 10mmPb , etc. (customizable) |
Operating speed | approximately 10-15cm/s (adjustable) |
Key advantages | Space saving: Compared to traditional single leaf large lead doors, it occupies less channel space when opened |
| Main application scenarios | 1. Radiology department of the hospital (CT room, DR room, interventional operating room, radiotherapy center) 2. Industrial non-destructive testing room 3. Nuclear power plants and facilities 4. Research laboratories (such as synchrotron radiation sources, nuclear physics laboratories) |
The core purpose and characteristics of the three overlapping lead doors are:
1.Partition isolation:
Divide the operating room into different clean or functional areas (such as the surgical core area, equipment area, and waste channel), and achieve directional flow of personnel and items through three doors to prevent cross contamination.
2.Ensure pressure difference:
Maintain a stable air pressure gradient between different areas through the opening and closing sequence of doors and sealing design (such as positive pressure in the operating room), ensuring that airflow always flows from the clean area to the relatively unclean area.
3.Radiation protection:
If there are fixed large radiation equipment such as DSA (Digital Subtraction Angiography) in the operating room, thick protective doors (usually lead doors) are necessary to shield X-rays and protect the safety of outdoor personnel.
4.Process optimization:
Design a reasonable door opening direction and linkage mechanism (such as interlocking function to prevent two doors from opening at the same time) to optimize the entry and exit paths of medical staff, patients, and equipment, and improve efficiency and safety.
A typical design of a triple layered lead door may include:
1.Patient/personnel entrance door: connecting corridor or preparation area.
2.Intermediate isolation door: forms a buffer zone.
3.Protective door in the core area of the operating room: equipped with radiation protection and the highest sealing performance.
The specific design (such as door material, opening method, interlock logic) needs to be strictly planned according to the actual level standards, equipment configuration, and hospital processes of the operating room.
