Abstract:
Ventilators are currently the most commonly used auxiliary mechanical ventilation equipment in clinical practice, and play an important role in the treatment of hypoxemia. Ventilator-associated pneumonia (VAP) is a special type of pulmonary parenchymal inflammation of nosocomial infection in patients with mechanical ventilation, which leads the increase of mortality and affects the prognosis of patients. The non-standard management of ventilator pipeline joints and the aerosol formed by bacterial condensate splashed from ventilator pipeline pollute the air, resulting in cross infection, which are the important reasons for VAP. The existing ventilator pipeline joint cap can achieve the effect of preventing pollution, but the clinical application compliance is not high. Based on the above factors, teachers, students and medical staff of the School of Public Health and Management, Guangxi University of Chinese Medicine and other units have designed a device for preventing pollution and air pollution of the ventilator pipeline joint, and obtained the national utility model patent of China (ZL 2020 2 1361981.X). The device is composed of a model lung, a mask body, a suspension part and a beam mouth part, etc. The use method is simple, and can be applied to the pollution avoidance of invasive ventilator and non-invasive ventilator pipeline joints, to reduce the occurrence of VAP in patients and the occupational exposure of medical staff.
