Description

Technical Field

[0001] The invention relates to a disinfection device for an imaging room, and in particular to an imaging room disinfection system and method. Background Art

[0002] Radiology is an important auxiliary examination department in hospitals. In modern hospital construction, radiology is a department that integrates examination, diagnosis and treatment. Many diseases in various clinical departments must be examined by radiology equipment to achieve clear diagnosis and auxiliary diagnosis. Radiology equipment generally includes ordinary X-ray machines, computer X-ray systems (CR), direct digital X-ray systems (DR), computer tomography (CT), magnetic resonance imaging (MRI), digital subtraction angiography systems (DSA), etc.

[0003] The imaging room is generally the main area for examination. At present, the imaging diagnostic equipment such as CT and DR in various hospitals plays a pivotal role in the prevention and control of tuberculosis and is an essential equipment for routine examinations. Patients with various diseases seriously pollute the imaging room (radiology equipment room) during the entire imaging scanning process. There are also some patients with infectious diseases who spread bacteria and viruses through the mouth, causing the air to be polluted to a certain extent. Patients who come to the imaging diagnosis center for treatment after the initial diagnosis by the doctor carry various bacteria and viruses. Therefore, the space inside the CT imaging room needs to be disinfected and sterilized. If it is not disinfected and sterilized in real time, it is bound to cause secondary contamination to normal patients undergoing normal imaging examinations, increasing the infection rate of unconfirmed cases. Therefore, it is very necessary to strictly disinfect the imaging room and the equipment after use.

[0004] At present, the disinfection of air and equipment in some imaging rooms has attracted the attention and concern of many professional companies in the world. The famous GPS (GE, PHLIPS, SIEMENS) has issued documents for the disinfection of imaging rooms for execution. However, many hospitals in China have not paid enough attention to this issue. The disinfection method used for imaging examination equipment is still mainly manual, which is basically arranged before and after get off work. There is a lack of special disinfection equipment, so the speed is slow and the effect is poor. The solution involved in the examination of such patients urgently needs a special equipment for rapid disinfection. Moreover, the existing disinfection equipment or disinfection system for imaging rooms cannot realize the disinfection operation according to the situation of the imaging room, resulting in poor disinfection quality of the imaging room and the inability to accurately and precisely disinfect.
