Description

Technical Field

[0001] The invention relates to the technical field of airtight escape doors, in particular to an airtight escape door for a medical operating room. Background Art

[0002] As a professional and vital medical service institution, the core mission of a hospital is to provide comprehensive and multi-level medical services to the general public, covering everything from basic disease diagnosis and treatment to complex and highly specialized medical interventions. In the complex system of the modern medical environment, the operating room is undoubtedly a special area with strict requirements on environmental conditions. The success of the operation and the life safety of the patient depend to a large extent on the precise control of the operating room environment. In order to ensure that the operation can proceed smoothly, the air quality in the operating room must be strictly controlled to prevent dust, microorganisms and other pollutants from causing infection risks to the surgical wound and minimize the possibility of surgical infection. Therefore, the operating room door, as the core component that isolates the operating room from the outside environment, is of self-evident importance. It not only needs to have excellent sealing performance, effectively blocking the invasion of various external pollutants, and ensuring that the clean environment inside the operating room is not disturbed by the outside world; it should also meet the functional requirements of convenience so that medical staff can quickly and efficiently enter and exit the operating room, while also ensuring that medical equipment The equipment can be smoothly transported and transferred, and the progress and efficiency of the operation will not be affected by the limitation of the door. In such a public building facility situation, the airtight escape door of the operating room has become an indispensable key safety facility for the hospital. Its core design purpose is to be able to open quickly in response to emergencies, thereby opening up an unobstructed escape channel for people in dangerous environments, so that they can quickly evacuate the building in the shortest time, away from potential dangerous areas, and maximize the safety of people's lives. Not only that, the airtight escape door also plays an extremely important role in isolation and protection in the medical environment. When facing some highly contagious disease outbreaks or specific infection risk areas, it can effectively isolate and close the source of infection area, prevent pathogens from spreading to other areas of the hospital through air, personnel flow and other channels, thereby effectively protecting the health and life safety of other patients, medical staff and visitors. This is particularly critical and important for special places such as hospitals with dense personnel, high mobility and the need to fully protect the safety of many people;

[0003] However, the airtight doors commonly used in hospitals currently have certain limitations. Most airtight door designs lack an independent swing door structure. This single door body design exposes many disadvantages during actual use. For example, once a power outage occurs, the airtight door that relies on electricity may be unable to open normally; in sudden disaster scenarios such as fire and earthquake, due to the influence of factors such as power supply interruption and building structure deformation, the automatic opening device of the airtight door is often difficult to work normally, which is not conducive to quickly opening the door body for personnel evacuation; in addition, if the power source of the sliding door body is damaged due to a fault and the automatic opening function cannot be realized, it will greatly reduce the success rate of personnel escape, and may even prevent personnel from escaping from the dangerous area in a timely and safe manner, thus causing serious safety accidents and posing a huge threat to the safety of life and property of hospital personnel.
