MCREAT has 16 years' experience in manufacturing medical intubation products. In terms of product technology and production, it is very mature and perfect. Since the World Anesthesia Conference in Amsterdam in 2019, I have talked with a German expert about the future direction of intubation-visualization of all intubation products is the future. Since 2020, the company has developed a series of products such as visual double-lumen bronchial intubation, visual laryngeal mask airway and visual obturator. In the future, the company's goal is to visualize all the inserted catheters (inserted into the body) in urology, gynecology, gastroenterology, etc. At present, the fiberscope and endoscope, which are expensive in hospitals, are made into disposable products. Avoid complete cross-infection, easy to use, protect doctors and patients.
