Description

Disposable Diagnostic Endoscope for Diagnosis of Upper Gastrointestinal Bleeding}

The present invention relates to a disposable diagnostic endoscope for diagnosing bleeding in the upper gastrointestinal tract, and more specifically, to a disposable diagnostic endoscope capable of visually confirming the presence and pattern of bleeding in the upper gastrointestinal tract in real time.

If upper gastrointestinal bleeding is suspected in an emergency room, intensive care unit, or hospital room of a semi-general hospital or larger, bleeding is determined by looking at the color of the saline water confirmed through gastric lavage through a Levin tube. It is difficult to accurately diagnose upper gastrointestinal bleeding with this method, and there are limitations in diagnosing duodenal bulb bleeding. Currently, in clinical practice, patients are referred to a gastrointestinal endoscopist after gastric lavage and, if necessary, upper endoscopy is performed.

However, the number of cases requiring hemostasis using an endoscope after gastric lavage is as low as about 16% in clinical practice, so the rate of emergency upper gastrointestinal endoscopy after gastric lavage that is unnecessary is very high. In other words, the accuracy of determining overt bleeding during gastric lavage is low. Inappropriate and excessive performance of emergency endoscopy is causing medical costs, excessive workload for emergency gastrointestinal endoscopy doctors and nurses, and increased fatigue leading to daytime work the next day.

Accordingly, for the purpose of checking for overt upper gastrointestinal bleeding in semi-general hospitals such as emergency rooms, a disposable diagnostic kit is needed that can be connected to the mobile phone of the emergency room medical staff on duty to visually check the presence and pattern of upper gastrointestinal bleeding in real time.

The matters described as the above background art are only for the purpose of improving the understanding of the background of the present invention, and should not be taken as an acknowledgment that they correspond to prior art already known to those skilled in the art.
