Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an operating room air environment monitoring device. Background Art

[0002] Air environment monitoring in the operating room is an important step to ensure a clean and safe operating room environment. This monitoring involves many aspects, including but not limited to: 1. Air quality testing: This is the basis for monitoring the air environment in the operating room. Air quality testing can assess the concentration of pollutants such as microorganisms, dust, and odors in the air to confirm whether the air quality in the operating room meets the cleanliness requirements. Common testing indicators include the concentration of bacteria and fungi in the air. 2. Surface cleanliness testing: The cleanliness of various surfaces in the operating room is also an important monitoring content. This can ensure that the sterile operating area is not contaminated. Common testing methods include irradiating with ultraviolet light after applying reagents on the surface to observe whether there is light. 3. Air flow testing: The direction and speed of air flow in the operating room are crucial to maintaining a clean environment. Through testing, it can be ensured that clean air flows from clean areas to contaminated areas to meet design requirements. Common testing methods include smoke testing and particle counter testing. 4. Noise testing: The noise level in the operating room is also a factor that needs attention. Maintaining a quiet environment during surgery helps avoid disturbing medical staff and patients. 5. Temperature and humidity testing: The temperature and humidity in the operating room are also important monitoring indicators. Appropriate temperature and humidity can ensure the comfort and stability of the surgical environment. Common testing indicators include temperature, relative humidity and dew point temperature.

[0003] Most of the air quality detection in the operating room is achieved by using an air quality detector, but the existing air quality detectors used in the operating room still have the following shortcomings: they are either handheld, which requires medical staff to frequently hold the detector to perform air detection, or desktop, which is placed on the desktop for air detection. No matter which of the above, it cannot be installed next to the operating bed, and it is not convenient for medical staff to check the air environment data inside the operating room in real time next to the bed (or during surgery).

[0004] Therefore, it is necessary to design an operating room air environment monitoring device that can be installed next to the operating bed to solve the above-mentioned problems. Utility Model Content
