Description

Endoscope for severe medical department

Technical Field

The utility model belongs to the field of medical instruments for ICU, and particularly relates to an endoscope for severe medical department.

Background

The diagnosis and treatment tools of gastrointestinal diseases in the critical medical department are very limited, and diagnosis and treatment are often carried out by relying on special doctors in the gastroenterology department and general surgery department. But with poor timeliness, especially in emergency situations, can lead to loss of valuable diagnostic opportunities for the patient. The nasogastric gastroscope is an endoscope which enters the upper digestive tract of a patient through the nose of the patient to diagnose and treat gastrointestinal diseases, but the operation method of the nasogastric gastroscope needs a special digestive endoscope training learning party to master, and has a longer learning curve. The matched equipment of the transnasal gastroscope comprises a trolley, a light source system, an image processing center, a display and the like, is inconvenient to quickly move to the side of a sickbed in the ICU, and is also inconvenient to quickly start operation. Meanwhile, the disinfection equipment of the nasogastric gastroscope is different from the existing bronchoscope disinfection equipment equipped with the ICU, and the disinfection work is difficult to be finished in situ. Nasogastric gastroscopes are expensive to manufacture, and are widely used in all ICUs due to the fact that they are several hundred thousand to several hundred thousand different.

In addition, tracheal intubation is an important technique for critical medicine and anesthesia, and difficult airways and tissue damage in the intubation are two problems that have not been addressed at all times. The early commonly used oral tracheal intubation devices were plain laryngoscopes, including reusable metal laryngoscopes and disposable plastic laryngoscopes. With the rapid development of modern video technology, video laryngoscopes are mainly used at present, the use principle of the video laryngoscopes is not essentially different from that of the traditional laryngoscopes, and the video laryngoscopes and the traditional laryngoscopes are not used for fundamentally solving the problems of difficult airway and tissue damage in the intubation process. The soft mirror guiding cannula through the mouth or the nose can well solve the problems.

The trend in the future is that doctors within the critical medical discipline should be able to find and solve most of the fundamental problems in every professional aspect.
